Genius In the Shadows

I would like to comment on David Hafemeister's review of Genius in the Shadows: A Biography of Leo Szilard (January 1994).

I have known the author, William Lanouette, for about 20 years. After I read his biography of Szilard, I wrote him to say that it might be misleading. He replied that he had tried to describe how Leo operated and how he sometimes achieved his objectives and often failed to do so.

Hafemeister's review may convey the impression that it was Leo Szilard who proposed how the United States should approach international control of atomic energy after the war ended in 1945. It is true that Leo invented and patented nuclear energy before fission had been discovered, led the allied effort to develop nuclear weapons, and in 1945 inspired the scientists at Chicago to consider what to do with the new technology after the war and to propose that the weapon be demonstrated to Japan rather than be dropped on a city. He was not successful in the latter case. As soon as the war was over he led the effort to block the May Johnson bill for control of nuclear energy because it would have permitted an active military officer to be on the part-time board of directors. As is explained in The New World, the first volume of the official history of the US Atomic Energy Commission, Vannevar Bush was the proponent of this bill which President Truman opposed. Niels Bohr was the thoughtful scientist who proposed what became the Achesson-Lillienthal plan for international control, embodied in and embellished by Bernard Baruch, who presented it to the United Nations in the spring of 1946. In 1943 Bohr tried to sell his proposal to Winston Churchill, who was not impressed. He visited Los Alamos several times in 1945 and I remember his discussing the subject with Robert Oppenheimer and several others at Oppie's house in the evening.

After leading the opposition to the May-Johnson bill, Leo was not much help in preventing the McMahon bill from becoming even more subject to military intervention than the original bill. Leo was not a team worker. I don't remember his ever supporting anyone else's ideas, e.g., the Acheson-Lillienthal proposal. In the fall of 1945, the Atomic scientists formed the National Committee on Atomic Information (NCAI), a voluntary association of about 60 national organizations ranging from the League of Women voters to the American Federation of Labor, to help in educating the public. Early in 1948, the NCAI decided to raise some funds to support our joint office. Harold Oram, the fund raiser, said that we had to have Einstein as a sponsor. To get him, we needed Leo Szilard; so we included them and several other distinguished physicists in the Emergency Committee of Atomic Scientists. The first appeal was enormously successful. As soon as Leo saw how much money had been collected, he persuaded Einstein and the other members of the committee to incorporate and to take charge of the money. He gave some of it to the NCAI. The rest of the money he spent on expensive brain storming sessions to generate ideas for international control. The only result that I remember is the proposal, mentioned by Hafemeister, to guarantee immunity for scientists or others who reported on violations of arms control agreements. It was a good idea, but ahead of its time.

Leo Szilard was a brilliant man. Bill Lanouette, with the assistance of Leo's brother, Bela, describes Leo's roots, modus operandi, accomplishments and failures very well indeed. Leo was a fascinating man, too sure that he was right, sometimes frustrating and often frustrated. It is a great book.

The Physics and Policy of Plutonium Disposition

Alex DeVolpi

Recent studies by the Office of Technology Assessment (1), the National Academy of Sciences (2), and other organizations encourage temporary measures to condition nuclear materials so they are less susceptible to diversion. Adoption of the NAS recommendation for interim--but indefinite--storage of pits and unadulterated plutonium would, I think, postpone irreversible arms reduction. Though surplus plutonium would be kept in secure storage, it would remain in forms that could be reused in weapons.

A shibboleth of some current policy analysis is that all plutonium is "weapons usable." This is a deceptive oversimplification that could result in delaying effective steps to defuse the caliber of weapons-grade plutonium. Moreover, it could provide a rationale to stall further nuclear arms reductions.

Some serious policy implications hinge on the semantics of weapons-usable plutonium. Some of these are outlined below, leading to a recommendation that the American Physical Society (APS) undertake to clarify certain technical issues and standards.

The arms control agenda
Prevailing problems for international arms control and nonproliferation, in order of urgency, are 1) management of existing weapons and fissile-material stocks, 2) deactivation of missiles and weapons, 3) termination of testing and production of nuclear weapons, 4) dismantlement and verification of warheads, 5) safeguarding of fissile materials, 6) demilitarization of uranium and plutonium, and 7) elimination of weapons-usable nuclear materials.

In terms of constructing an international context for these problems, the NAS report provides a thorough review and identification of significant policy choices. However, some conclusions of the Academy's committee are influenced by issues extraneous to the problems of arms control. In particular, the hypothetical threat of diversion is magnified by the same technique used to sustain the Cold War, namely worst-case analysis. In William Arkin's words (3), "proliferation is methadone for Cold Warriors who can no longer get the real thing."

As Thomas Cochran, Nuclear Program Coordinator for the Natural Resources Defense Council, continues to emphasize (4), the "main problem" is the diversion risk of separated fissile materials in Russia, where unstable conditions exist now. Other problems there include military reactors now needed to produce heat and electricity.

Of the 125,000 nuclear weapons manufactured globally, about 50,000 remain in stockpiles. Over 250 tonnes of weapons-grade plutonium and over 2100 tonnes of highly enriched uranium were produced for these weapons. Civilian plutonium stockpiles are even larger, being created at the rate of 1 kg from every tonne of mined uranium.

Is the task of controlling plutonium so intractable that the only solutions are to curtail all reprocessing and shut down all nuclear reactors?

The physics of isotopic depletion
Technical analysis (5) shows that both weapons uranium and plutonium can be degraded by isotopic depletion, that is, replacing fissile isotopes with fertile isotopes. A natural dilutent exists for uranium, and artificial dilutents can be manufactured for plutonium.

The NAS report has a disappointingly imprecise description of the differences between reactor and weapons plutonium. Moreover, their discussion of isotopics does not go beyond reactor-grade plutonium. Higher burnup can further degrade plutonium, even without recycle. Eleven physical effects deleterious to explosive potential occur when the even-isotope fraction of plutonium is increased. The average explosive yield decreases and the statistical uncertainty in yield worsens.

The means have been demonstrated worldwide to demilitarize plutonium by increasing the fraction of its even-isotopes. Advanced reactors are not necessary for this purpose, as operating reactors can demilitarize plutonium sufficiently to exclude its return to existing nuclear warheads. Durable nuclear weapons have been designed, constructed, and tested to satisfy military objectives. If refitted with sub-grade plutonium, precisely machined military weapons cannot be effective, fusion boosting is likely to be less useful, and secondary fusion of multistage thermonuclear weapons would not be properly triggered.

Of fifteen nations known to have produced nuclear weapons or to have embarked on their development, none have chosen anything less than high-quality fissile materials.

Therefore, both fundamental physics and historical experience reinforce the military inadequacy of poor grades of fissile materials. Of course, safeguards need to be maintained and enhanced to deter diversion and production of all fissile materials, civilian and military.

Reference (5) is a 100-page technical review and analysis of plutonium disposition options, containing specific technical data and estimates of explosive yields.

Demilitarization benefits
Plutonium demilitarization will not only buy time, it might avert policy disappointments. Although military and civilian plutonium should not have fundamentally different material controls and accountability (6), they could be treated in two distinct time phases to conform with national security, economic, and technical constraints. Developing a practical methodology for keeping plutonium from being reused in existing warheads should be a major priority.

One example of a looming policy disappointment is the fissile-material production cutoff. Although agreements have been reached for shutting down three Russian plutonium production reactors, no deadline has been negotiated. Thus, indefinite reactor operation with current fuel and burnup would have the effect of prolonging weapons-grade output and processing. Instead, Russian military reactors could be upgraded in safety and quickly modified to yield low-grade plutonium. Russian resistance to immediate reactor shutdown is primarily based on the need for electricity and heat--lacking deliverable interim alternatives.

Another example related to demilitarization is the "spent-fuel standard" proposed by the NAS: The standard might be a more formidable barrier than credited. Mixing U.S. weapons-grade plutonium with existing spent fuel is likely to give sufficient chemical, radioactive, and isotopic contamination to render it too difficult for reuse in weapons. In fact, if weapons and separated reactor plutonium were blended in equal proportions, the resulting "fuel-grade" mixture might be sufficiently demilitarized without additional reactor burnup.

A consequence of a perceived inability to demilitarize plutonium is the unintended strengthening of the argument that further arms reductions should be delayed. If all plutonium were truly "weapons usable", there would be little incentive to dismantle and demilitarize nuclear weapons.

Elimination of plutonium
Another policy dilemma is emerging over the ultimate disposition of plutonium. If the recommendations in the reports cited above were adopted, a stronger rationale might be created for postponing deep cuts in nuclear arsenals.

The Presidential Nonproliferation and Export Policy Statement of 27 September 1993 establishes an interagency group to review long-term options for plutonium disposition, inviting other nations to participate in the study. The Department of Energy, under special assistant Robert DeGrasse, is organizing its own initiative for "safe, secure, environmentally sound control, storage, and ultimate disposition of surplus fissile materials".

The most realistic options for long-term disposition of U.S. plutonium are storage and fission. For geologic storage, plutonium would be sorted underground as vitrified waste in corrosion-resistant containers. For destruction by fission, either nuclear reactors or accelerators could be used.

Research policy is likely to be more effective if expressed in terms of goals rather than singling out specific means. Some examples regarding vitrification and fission illustrate the stakes involved in prematurely focusing on specific choices.

Vitrification has serious flaws
The most touted form of storage--mixing heavy doses of weapons-grade plutonium into radiologically contaminated vitrified waste--has two afflictions from which it might never be free: the need for perpetual safeguards and the risk of nuclear criticality.

Vitrified weapons plutonium would remain forever recoverable. Chemically re-separating plutonium after vitrification is considered less difficult than deriving cocaine from cocoa leaves (7). The main benefit of radioactive and chemical contamination--without isotopic depletion--is the creation of a rate-limited barrier to quick reconstitution.

The other serious problem with vitrification of plutonium is susceptibility to an uncontrolled nuclear chain reaction. Proposed mixtures of plutonium in borated glass have ranged from 0.1 wt% to more than 4 wt% plutonium in a 1.5 tonne glass log. Because the smaller fraction is considered expensive, consideration has focused on incorporating at least 3 wt%. This amounts to about 45 kg of pure plutonium in a single log; yet much less than 1 kg could become critical if moderated by water. Hampered by the fact that intruding water can readily leach boron differentially, one would have to prove that each log would remain subcritical under foreseeable conditions (7). Both criticality physics and derivative regulatory requirements would stand as serious obstacles to licensing.

These flaws could be fatal for vitrified plutonium, because freedom from these technical concerns might never by provable (8).

Responsibility should not be postponed
Another problem with geologic storage is an extension of the NIMBY (not in my backyard) syndrome, namely NIMT: not in my time: Put it off for future generations. Instead, the national goal should be to eliminate plutonium. Our Cold War generation created the dilemma, and we should not transfer the cost and problems to future generations.

Although recognizing fission as an option for plutonium elimination, the National Academy report proposes that the U.S. limit itself to undefined "conceptual" research for advanced options--foregoing modest development and demonstration of existing, promising ideas. The Academy places the hypothetical risk of reactor-grade material diversion above the contemporary dangers of weapons-grade plutonium.

Because the NAS concludes, "consumption fractions...between 50 and 80 percent...are not sufficient to greatly alter the security risks posed by the [plutonium] remaining in the spent fuel," they advise that "...technologies designed to fission or transmute nearly 100 percent of the plutonium are the only plausible elimination approaches." However, if demilitarization of plutonium at lesser grades were accepted, such extreme burnup measures would be unnecessary.

APS role
As indicated in the foregoing examples, functional definitions can affect policy choices. Toward both interim and ultimate goals, standards need to be formulated for demilitarizing and denaturing weapons-grade plutonium. For this purpose, an independent scientific organization such as the APS could fulfill an important role.

Policy decisions on fissile material disposal options should be based on assessment that have objective criteria. The government will have to establish explicit priorities for environmental impact, cost avoidance, energy recovery, economic subsidies, public risk, nonproliferation concerns, and rearmament peril. A cost-benefit-risk public-policy equation ought to be adopted and its implications understood.

The utility of fissionable materials in the manufacture of nuclear weapons is subject to confusion and obscuration, some rooted in semantics and policy disputes. This is in contrast to the reality that reactor-grade plutonium is yet to be chosen for militarization by any of the acknowledged or suspected nuclear-weapons states.

The semantic issue is centered in part on definitions of nuclear weapons. Those who fear the malevolent use of low-grade nuclear materials stress that a devastating fission explosive can be made with any isotopes of plutonium. This qualitative contention is quite misleading. Policy-makers need to have a more sophisticated understanding of the relative risks and tradeoffs for fissile materials, especially reactor-grade plutonium. Based on the fundamental physics of nuclear reactions, standards for reconstitution of plutonium in existing weapons could be devised.

During its comprehensive treatment of the nuclear fuel cycle in 1978 (9), the APS examined issues related to isotopic denaturing, drawing some qualitative conclusions. Picking up at that point, a limited study could help in developing standards, allowing for information that has been more recently declassified and discovered about domestic and foreign programs.

Until eliminated, international plutonium will need to be cooperatively managed. Meanwhile, research, development, and demonstration could be conducted to benefit sound policy choices. The present administration should not defer action to another generation. Qualified scientists could help in establishing goals and standards for timely and cost-effective plutonium disposition.

Public Briefing on Management and Disposition of Excess Weapons Plutonium

Wolfgang K.H. Panofsky

[In order to provide perspective on the preceding article by Alex DeVolpi, Physics and Society presents here the public briefing by the chairman of the NAS study on the management and disposition of excess weapons plutonium.]

With the end of the Cold War, nuclear arms reductions on an unprecedented scale are underway. If current plans are successfully implemented, tens of thousands of nuclear weapons will be dismantled over the next decade. This represents an historical moment of great hope, but also of danger.

The weapons plutonium problem
The weapons to be dismantled contain 100 tons or more of plutonium and hundreds of tons of highly-enriched uranium. These materials are the essential ingredients of nuclear weapons, and limiting access to them is the primary remaining technical barrier to the spread of nuclear weapons capability in the world today. Managing, securing, and accounting for these materials--when even a grapefruit-sized ball weighing only several kilograms would be enough to make a nuclear bomb--will be a monumental task. Indeed, this is one of the most pressing security challenges facing our country today. Plutonium poses special difficulties, as unlike highly-enriched uranium, it cannot be easily "blended down" to a proliferation-resistant form, and it cannot compete economically in the current market for nuclear fuels.

In the former Soviet Union, this security challenge is further complicated by the enormous political, economic, and social upheavals now underway. The risk remains that Ukraine may still decide to go the nuclear road, a possibility that would deal a devastating blow to arms reduction and nonproliferation. And the risk that weapons-grade materials could be stolen in the former Soviet Union remains all too real. Unless urgent action is taken, any day now we could wake up and read in the morning newspaper that enough material for a dozen bombs really had been stolen. There are many false alarms already.

Faced with this situation, the U.S. National Security Council asked the National Academy of Sciences' Committee on International Security and Arms Control to make recommendations on appropriate policy steps for the management and disposition of excess weapons plutonium. Our report is being released here today. It covers three stages of the process of reductions--dismantlement of nuclear weapons, storage of the resulting fissile materials, and long-term disposition of those materials--as well as a broad transparency regime designed to apply to all nuclear weapons and fissile materials, and therefore to all three of these stages. An additional report providing more detail on the reactor-related options for long-term disposition of plutonium, prepared by a separate panel commissioned by the Committee, will be released in about eight weeks, after peer review. All of the main conclusions of that future report, however, are included in the document we are releasing today.

These excess weapons materials, particularly those in the former Soviet Union, pose a clear and present danger to international security. Reducing that security risk must be the driving force in deciding our policy; exploiting the plutonium's energy value (which is tiny on the scale of global energy needs), or influencing the future of nuclear power, are secondary issues. The steps we recommend are designed to meet three key security objectives:

  • To minimized the risk that either weapons or fissile materials could be obtained by unauthorized parties;
  • To minimize the risk that weapons or fissile materials could be reintroduced into the arsenals from which they came, halting or reversing the arms reduction process;
  • To strengthen the national and international arms control mechanisms and incentives designed to assure continued arms reductions and prevent the spread of nuclear weapons.

Management of this plutonium must also meet high standards of protection for environment, safety, and health.

Four recommendations
Our recommendations fall into four major areas:

First, we recommend a sweeping new agreement under which the United States and Russia would exchange information on their entire stocks of nuclear weapons and fissile materials. This declaratory regime would be coupled with cooperative monitoring to confirm the information exchanged. A verified cutoff of production of fissile materials for weapons, and monitoring of weapons dismantlement would be key parts of this regime. In particular, we conclude that weapons dismantlement can be monitored without compromising sensitive information, and without imposing substantial delays and costs. Such improved openness and accounting, we believe, would strengthen efforts to reduce nuclear arms and stem their spread, reduce the risks that nuclear materials might "go missing," and allow more democratic participation in decision-making. Virtually none of this regime is yet in place, though the Department of Energy's recent declassifications of the amounts of plutonium produced for the U.S. nuclear arsenal is a most welcome first step.

Second, the United states and Russia should pursue a reciprocal regime of secure, internationally monitored storage of fissile material, with the aim of ensuring that the inventory in storage can only be withdrawn for non-weapons purposes. Both nations should explicitly commit a very large fraction of their nuclear materials from dismantled weapons to non-weapons use or disposal under international safeguards. No such international transparency arrangements are yet in place, though President Clinton announced on 27 September 1993 that U.S. excess weapons materials would be placed under safeguards, and President Yeltsin's government has announced its willingness to do the same.

Third, with respect to long-term disposition, we offer not a final answer but a road map for arriving at one: we outline the criteria on which decisions should be based, the reasons for rejecting most of the options that have been proposed, and the questions to be answered before any one of the remaining contenders could be confidently chosen as the preferred approach. We recommend that the United States and Russia pursue long-term disposition options that:

  • minimize the time during which the plutonium is stored in forms readily usable for nuclear weapons;
  • preserve accounting and security during the disposition process, seeking to meet a "stored weapons standard"--that is, maintaining the same high standards of security and accounting applied to stored nuclear weapons;
  • result in a form which meets a "spent fuel standard"--that is, making the weapons plutonium as difficult to recover for weapons use as the larger and growing quantity of plutonium in commercial spent fuel worldwide;
  • meet high standards of protection for environment, safety, and health.

The two most promising alternatives for this purpose are:

  • the spent fuel option, in which the plutonium would be used as fuel in existing or modified nuclear reactors (such as U.S. and Russian light-water reactors, or Canadian CANDU heavy-water reactors), which would consume a fraction of the plutonium and embed the rest in highly radioactive spent fuel similar to that now produced by these reactors; and
  • the vitrification option, in which the plutonium would be mixed with intensely radioactive high-level wastes, which are scheduled to be mixed with molten glass to form huge glass logs for ultimate disposal in an underground repository.

A third option, burial in deep boreholes, has until now been less thoroughly studied than the first two, but could turn out to be comparably attractive.

We have concluded that advanced nuclear reactors should not be specifically developed or built for the mission of transforming weapons plutonium into spent fuel, because that aim can be achieved more rapidly, less expensively, and more surely be using existing or evolutionary reactor types.

Fourth, we recommend using the immediate need to deal with excess weapons materials as an opportunity to set a standard of improved security and accounting that would be applied to all fissile materials world-wide. The excess weapons plutonium is only a small part of the global plutonium stock, which includes many hundreds of tons of plutonium in spent fuel, almost 90 tons of separated civilian plutonium, plutonium in scrap and residues, and other materials. We recommend that the United States pursue new agreements to ensure that all civil fissile materials world-wide are under safeguards, with stringent standards of security and accounting. Most urgently, we must take steps to cooperate with Russia to reduce the real danger that weapons-usable materials might be stolen; the spread of nuclear weapons is perhaps the greatest threat to U.S. and international security today, and this risk of theft is one of the greatest current sources of that threat. We have outlined a series of urgent steps that should be taken. New consideration is also needed of steps to further reduce the long-term proliferation risks of all fissile materials, including plutonium in spent fuel; this global effort should include continued consideration of more proliferation-resistant nuclear fuel cycles, including technical concepts that might offer long-term options for a nearly "plutonium free world."

None of the approaches we have identified can eliminate the dangers posed by these materials. All they can do is to reduce the risks. Even the best of the disposition methods cannot make a significant dent in the stockpiles of excess plutonium for more than a decade. Thus the world is condemned to "baby-sit" this dangerous stockpile for many years to come. We believe the U.S. government should elevate the priority given to these issues. A more systematic interagency approach is needed, with leadership from the top, and new initiatives to cooperate with Russia in addressing these challenges. Precisely because management of this plutonium will be a long and complex endeavor, it is important to begin now.

Symposium: After the Cold War: What Now for Science? A Discussion of Economic Conversion

The following three articles are based on talks given at our Forum's invited symposium held at the March 1993 APS meeting in Seattle, Washington. A fourth article based on this symposium, "An Insider's Perspective: Grappling with Change at TRW" by Jeff Newman, appeared in our previous issue (July 1994). Physics and Society was unable to obtain a copy of the other talk at this symposium, "Government funding for basic research in physics," presented by Melvin Lax, City College of the City University of New York.

Introduction to the Forum on Economic Conversion

George Reiter

It is a remarkable fact that three years after the disintegration of the Soviet Union, and in a climate of fiscal austerity, a $262 billion dollar "defense" budget, larger than the average budget, in real dollars, during the cold war period, and containing such manifestly pointless and expensive items as B-2 bombers, D-5 missiles, and F-22 fighters, passed the house in 12 minutes. We are told by the president, in his state of union address, to wild applause, that we will not compromise our defenses by any further cuts in that budget. This, even though the enemies the defense department can muster up are so implausible that we must be assured that it is necessary to fight two of them simultaneously and independently in order to conjure up a sufficient threat. Such an overwhelming political consensus is a tribute to the central role that military spending has played in sustaining our economy during a decade and a half of military Keynseanism.

Such spending has had a disastrous effect on the economy. The growth of manufacturing productivity over the last decade in this country has been the slowest of any industrialized nation. While it is difficult to assign causal relationships in such a complex system, it is the case that countries that spend less on the military have higher rates of growth of productivity, and that military Keynseanism is the least effective form of Keynseanism, producing significantly fewer jobs compared to what would have occurred if the money were spent in the civilian economy. It is also common sense that if you have forty percent of your scientists and engineers engaged in projects whose end product is something that you may put in a hole in the ground and hope never to use, you will not be doing as well as if those people were working on doing something new and useful for the civilian society, the spin off argument not-withstanding.

Physicists, whether in universities, national labs or industry, have a direct stake in the question of how the Cold War defense budget is to be reallocated. For those in labs such as Livermore or Los Alamos, or in the defense industries of Southern California, the stake is immediate and obvious. But even those of us in universities with no direct funding from the defense department, have a major interest in the outcome of what has so far been a non-debate.

The transfer of Federal funds to the military has been at the expense of all other federal programs, with the exception of the S&L bailout, and has resulted in direct losses to state budgets, both from having less federal funds, and from having to pick up social programs the federal government was no longer funding. At the same time the general weakening of the economy by the diversion of resources to non-productive use has limited the ability of the state to raise revenue by taxation and exacerbated the social need for services. As a consequence, many states are in financial trouble. Higher education is a significant part of most state budgets, and an area where cuts do not, in the short run, produce major dysfunction and outrage. As a consequence we have seen a widespread attack on university budgets throughout the country. At the same time, universities are being asked to remedy the effects of decades of waste of resources on the productivity of our industrial base by encouraging technology transfers and joint ventures with industrial partners. In fact, such transfers have always occurred, as Silicon Valley and the Golden Triangle attest. There has been no study of the ecology of science that indicates that the present network of interactions between basic science, technological projects, and industry is in any way flawed or ineffective. The pressure does not reflect any deep understanding of the way our society works, but is essentially a political attack. This attack has the effect of shifting the emphasis in universities from scholarship to entrepeneurship, from inquiry based on intellectual curiosity and wonder to an instrumental notion of research, and could succeed in severely damaging the creative core of science in this country.

With the sense that the problem of the conversion of the military economy to a civilian one was both a central issue for society and one in which physicists needed to be involved and to take a stand, we brought together a panel of people who have been fighting this battle for some time. Seymour Melman has for decades been providing intellectual leadership to bring attention and rationality to the problems created by the growth of the military economy. Frank Emspak has been working extensively with people throughout the country who have been developing and implementing practical plans to convert their own workplaces to civilian use. Jeff Newman [Physics and Society, April 1994, p. 4], trained as a physicist, was active in a program at TRW Systems to find ways to produce products for the civilian market. His story illustrates some of the difficulties involved, and affirms Emspak's point on the need for a coordinated societal industrial policy, if we are to succeed in directing our resources back to useful production. More than that may be needed.

The existing structures of our society, as we have witnessed, have sustained the military economy long past the point that any rational argument for its existence could be made. It is worth asking if any interpretation of events can explain the persistence of such a feature. Of course, one could point to the fact that profits in defense industries are twice as high as those in other industries, on average, as sufficient explanation. Putting that fact in a larger context, while recognizing the difficulty of analyzing a system as complex as our society, I find the following interpretation to be the most convincing analysis that I know of.

The polarization of our society that has been going on for two decades, with the great majority of the population experiencing declining real wages, and the financial benefits of increased productivity being experienced by only the top few percent whose incomes have risen dramatically, has meant that the majority of people cannot buy back all that their labor has produced. Productivity is so high now, that the top few percent cannot consume the remainder of what is produced either. There are, after all, just so many Mercedes, houses and shoes that one can put to use. The military economy in this light, is seen as an essential source of waste, allowing profits to be made without the necessity of having to produce goods that would have to be sold to a population that cannot afford them. Our children then pay for the things produces and wasted in the form of taxes to pay off the national debt.

If such an interpretation of the dynamic of our society is substantially correct, we will not be able to convert the military economy to civilian purposes without a fundamental restructuring of our economy as a whole. Conversion will be difficult enough in any case, and it is essential that it be done. I invite you to join in the debate and action required to do it.

Notes on Disarmament

Seymour Melman

The long U.S. Cold War experience included a concentration of government supported R&D funding on military as against "advancement of research" objectives. Thus, for 1989, the percent of total government R&D spending for military purposes was:

U.S. 65.6%
Germany 19.0%
Japan 9.0%

For the same year the percents by each government for "advancement of research" were:

U.S. 3.8%
Germany 20.7%
Japan 13.8%

Similar experiences--all unfavorable to the U.S.--were evident in R&D resources addressed to "energy" and to "industrial development."Similar experiences--all unfavorable to the U.S.--were evident in R&D resources addressed to "energy" and to "industrial development."These and related data are from the National Science Board, The Comparative Strength of U.S. Science and Technology: Strategic Issues, Washington, D.C., 1992. They are, in my view, a powerful justification for attention by the science community to the problems of carrying out a reversal of the long arms race. Disarmament is the name of the process of demilitarization that must be fashioned and set in motion everywhere.

Accordingly, I offer these Notes on Disarmament, based upon my The Demilitarized Society: Conversion and Disarmament, Harvest House, Montreal, 1988.

Disarmament discussions prior to 1962
Disarmament is a process for diminishing the power of war-making institutions by mutual agreement among governments. Mutual agreement on military, political, and economic matters must include, crucially, agreements for the carefully phased and inspected reduction of armed forces, weapons, budgets, military-serving factories, laboratories, bases, and the number of people--civilian and uniformed--under their control.

More than a definition of disarmament is needed at this time. For Americans educated in U.S. high schools and universities from 1963 to 1993 were not informed about the idea of disarmament. If mentioned at all, then it was treated as a visionary ideal at best and, at worst, a device for leaving the U.S.helpless, without weapons in the face of Soviet threat. Most important perhaps, what was wiped out during 1963-1993 was the fact that the U.S. government, in the person of President Kennedy, had formally presented plans for carrying out a reversal of the arms race, and that this had been done in concert with the Soviets. That history was simply withdrawn from public discussion--put down the memory hold after the Orwellian fashion of 1984.

While the expansion of Department of Defense budgets dominated the activity of President Kennedy's first year in office, there were also initiatives in other directions. With strong encouragement and support from his science advisor Jerome Wiesner and leading members of the Senate (notably Hubert Humphrey and Joseph Clark), President Kennedy supported legislation establishing an Arms Control and Disarmament Agency in the State Department. To chair the advisory committee of that agency Kennedy appointed John J. McCloy, then recently retired as president of the Chase Bank in New York City. McCloy took this post very seriously, and proceeded to address banking and other business groups from coast to coast arguing the importance of peace and disarmament on economic, moral and political grounds.

During 1961, in order to explore the international disarmament terrain, McCloy engaged in discussions with Valerian Zorin, the Soviet chief UN delegate. Following six meetings in the U.S. and Europe, these men formulated a three-page text comprising a set of criteria, principles to which detailed disarmament plans by the U.S. and Soviet governments should conform. This short text was announced with much fanfare and was unanimously adopted by the UN General Assembly. Thereafter, senior government staffs in both the U.S. and the Soviet Union proceeded to formulate disarmament plans.

President Kennedy announced the U.S. disarmament plan in April 1962. The proposal bore the title "Blueprint for the Peace Race: The U.S. Plan for General and Complete Disarmament in a Peaceful World." The Soviet disarmament plan was formally presented in September 1962.

But the Cuban Missile of October 1962 put an end to serious negotiation on these disarmament proposals. The Soviet high command emerged from that crisis with determination never to be caught again in the same position of gross military inferiority. On the American side, the dominant view in the White House staff was one of exhilaration: they had learned how to play nuclear chicken and win. Thereafter the Cuban Missile Crisis was celebrated as a crowning and model achievement in the wielding of nuclear military power for political effect.

Managing (not reversing) the arms race since 1962
Against this background, arms control strategy for managing (not reversing) the arms race dominated the field. The arms race was to be made into managed, regulated activity, to the exclusion of disarmament. Soon after the Kennedy administration was established in 1961, concerted efforts were launched by departments of the government, by the major private foundations, by principal universities--all to the point of establishing arms control, the regulation of the arms race, as the primary orientation for wielding American military/political power--all this at the side of strategic studies with their classic emphasis on superiority in military/political operations.

The Ford and Rockefeller Foundations, which together have accounted for about 85 percent of international relations research grants at American Universities, set in motion elaborate programs of arms control activities: institutes, seminars, conferences, research grants, journals. The word was out in the universities: graduate students and university faculties could immediately see where money was to be had for graduate work in international affairs. The arms control emphasis by the foundations and the universities was, of course, strongly supported and politically validated by the participation of senior members of the government in arms control and arms control-related activities.

As for disarmament: no research grants from the major foundations; no research grants at all from the U.S. Arms Control and Disarmament Agency; no courses at universities; no doctoral dissertations leading to degrees on disarmament topics; no treatment of disarmament topics in major journals of opinion. For twenty-five years, major publishers did not produce a single book on disarmament authored by an American writer.

But by 1988 the blackout on the idea of reversing the arms began to dissipate. After forty years of arms race and Cold War, parts of the ruling elites of the U.S. and the Soviet Union confronted their internal economic condition and found that grave problems could not be addressed without damping down and reversing the arms race (1). The idea of disarmament could no longer be kept under wraps. The very onset of the U.S. debate on the Intermediate Nuclear Force Treaty set in motion a discussion that called attention to the merits and limitations of this treaty, not only within a narrow compass, but also in light of possible future agreements--as on intercontinental ballistic missiles and with respect to conventional forces. That discussion compelled attention to the merits of formulating an orderly process for carrying out a reversal of the arms race in all its aspects. In order to do that, we will need to address a series of problems that are intrinsic to a disarmament process.

Disarmament problems today
Since 1962 virtually no attention has been given to the problems of designing, negotiating, and implementing a disarmament process in the principle countries of the world. Moreover, since that time the technical, political, and economic problems entailed in reversing the arms race have been complicated by the great enlargement of armed forces, the stockpile of their weapons, the size of their budgets and of supporting manufacturing and scientific establishments. Accordingly, it is vitally important to give fresh attention to the array of problems whose solution is essential for confidence in designing and implementing a disarmament process.

I start from the assumption that mutual assurance for carrying out a disarmament process for common security cannot be achieved on the basis of vaguely defined mutual trust. Thus, reliable inspection methods are needed to verify compliance with the terms of a disarmament process.

In the ordinary conduct of our lives, we rely on compliance with a great array of agreements on codes of behavior whose violation is commonly viewed as unthinkable, even apart from the presence of law-enforcing institutions. A special problem surrounding a disarmament process is that its subject is a network of war-making institutions whose operators have along tradition and extensive training in secrecy, deception, surprise, and evasion--the better to overcome the opponent. These ordinary, thinkable and valued aspects of military institutions, together with the many millions of people who participate in them, tell us that the design and execution of a disarmament process must give elaborate attention to workable and reliable ways of ensuring compliance by the participating states. This will require multiple barriers against successful evasion of the terms of a disarmament agreement. That assessment derives not from a paranoid, unreasonably exaggerated view of armed forces and their supporting organizations, but rather from sober and prudent understanding of quantity and quality of resources that have been made available to secret intelligence and military organizations trained to carry out covert military, political, industrial and research operations on a large scale.

On a recent visit to Los Alamos National Laboratories, I found that scientists in its X-Division--responsible for all aspects of nuclear warhead design--are probably one of the best equipped groups in the world to carry out functions under a demilitarization process. Recall that there are now tens of thousands of nuclear warheads in the nuclear states, and a disarmament process cannot--for obvious reasons--tolerate an accounting error or physical loss of even one whole warhead or component. This imposes unprecedented requirements for inventory reliability.

However, since the physical inspection and control methods cannot offer 100 percent reliability, such conventional methods would have to be supplemented by ways of observing people. That leads me to ask: By what means could scientists observe the professional activities of their colleagues so as to make any effort to evade a disarmament agreement vulnerable to detection?

Such issues were first addressed 35 years ago (in my report on Inspection for Disarmament, Columbia University Press, 1958). It is now timely to address these issues once again.

A Discussion of Economic Conversion

Frank Emspak

Conversion means the redeployment of existing machinery, capital, intellectual and managerial talent from the manufacture, design and sale of military goods to goods and services that supply or support the commercial, non-military sectors of the society. Conversion implies changeover of existing systems. The notion harkens back to the conversion of the WW II production system to producing civilian goods. In that case many of the same factories used for the production of war material were transformed into the production of civilian goods with little delay.

Diversification suggests a less complete redeployment of productive capacity. It implies that an institution primarily dedicated to military work broadens its product line. Diversification can be carried out by expanding the products produced in one place to include non-military goods, or it can be accomplished by acquisition of new plants and sale or abandonment of military facilities. However diversification implies that the firm will maintain some military production.

We favor conversion in place. This means that we emphasize maintaining the capital investments, physical plant and above all that organism that represents the sum total of skills, abilities and interactions of a functioning factory or work place. We favor policies that maximize the possibilities of converting existing institutions from military work to productive, profitable non-military work. We would want to use a substantial amount of the existing capital equipment and most of all, the manpower associated with current defense production.

We favor a conversion-in-place strategy over the "close and migrate" strategy, although we recognize that some dislocation will undoubtedly occur especially as remote bases and specialized military support facilities are closed. However the idea that defense workers should be laid off, retrained for jobs that may not exist, migrate to those new jobs, and then become re-employed, does not appear to be a good policy option.

Some of the impediments to a conversion in place strategy
Unlike after WWII there are severe structural barriers to immediate conversion. Among them are:

No markets. After WWII there was the phenomenon of "pent-up demand." In the U.S. there was a hunger and ability to pay for civilian products especially consumer durables such as housing and automobiles. Today these markets are saturated and in addition American producers face extreme competition in these areas.

Export demand. The domestic markets were supplemented by large potential export markets--especially in consumer durables and capital goods. The export market was stimulated by the Marshall plan, but nonetheless contributed to a net need for production. The export markets today are also the scene of extreme competition and our European and Japanese competitors produce many of the same items competitively with American produced goods and services.

Divergence in production methods. After WWII, especially in consumer durables, the changeover from military production to civilian production was relatively simple. This is no longer the case.

Divergence in design methods. Design is the more important and controlling factor--as compared with production. Over the last 50 years a military design culture has grown up. Defense design criteria emphasize performance with cost a secondary factor. In commercial markets, performance, cost, and throughput time must be taken into consideration with special emphasis on cost and throughput time. Simplicity, meaning ease of production, also becomes more important.

All of the above taken together suggest that conversion in place will not be immediate. Even if there are policy decisions to maximize such a strategy, there will be a necessary period of market development, retraining of engineers, and designers (not so much the skilled work force) and product development before full productive employment will be achieved.

Advantages of a conversion in place strategy
A skilled work force. There exists in the defense industry, and especially in the electronic and aircraft industry, the most skilled and technologically literate blue collar work force compared to any industrial sector. The engineering, design and technical work force is also among the most skilled and knowledgeable in the American economy.

Modern facilities. A good proportion of US industrial defense production takes place in highly capitalized and modern facilities. Machinery and communications systems are often new and in some cases "state of the art".

Significant installed capacity. This is a corollary to number two. The machinery and equipment is in place. There is not necessarily a need to write off investment but rather alter or reconfigure. Sometimes we forget that machine tools and a good deal of manufacturing equipment in general is "universal"--specific pieces of equipment can make many parts.

Publicly Owned Assets. Assets that are already government owned could play a special place in developing a conversion program. Government owened but privately operated facilities may be a means to experiment with alternative use committees, democratic development and labor management committees with significant authority. Perhaps as one means of encouraging conversion the firms would only be allowed to hold the contract if they worked with the work force and communities to convert.

The best strategy
What strategy can we pursue that will make the best of existing work force skills and the installed manufacturing and R&D base? In the first place we must convince the defense dependent firms to talk with their work force about the future. The same idea applies to base closures and to government owned but contractor operated facilities. I emphasize the proposition "with." Talking with someone implies back and forth discussion--dialogue. It implies a recognition of the other party.

In the framework of current labor relations we call the above mechanism "Labor-management co-operation". It sounds trite but it is not. Our definition of co-operation goes beyond good will and nice phrases. Serious co-operation in unionized firms would mean negotiations with the work force regarding what is possible to produce in the plant and a strategy to achieve the development and manufacture of new products.

Such co-operation would include, but not be limited to joint design of training and education, inclusive of both the technical and blue collar work force; and restructuring of authority and concomitantly the division of labor so as to involve a segment of the work force in the redesign and transformation of existing production methods to meet those of the new more competitive commercial environment.

An illustrative example
The above system has worked in a variety of places, but I would like to give an example of one plant: the AM General Facility in South Bend Indiana. The factory makes the HUMVEE--the funny looking truck/jeep. It is an off-road vehicle.

Their program started in the summer of 1990 when the union, UAW local 5, insisted that the firm work with them to engage in a "self-directed work project". The object was for a union work team to build an ambulance body and place it on the truck chassis. The ambulance was in part for the military and in part for governmental but not necessarily military use. At any rate we were asked to come in and train the team and work with the company and union to find ways to empower the work force to solve problems. Of course, the management had to let go of some of their authority. The ambulance project was a success and ambulances were built at about 60% of the previous cost and with much higher quality.

That project encouraged the union to insist that the firm do other projects--namely a civilian humvee. To that end the AM General has begun to produce a civilian version. There have been some redesign of the vehicle.

Meanwhile the DoD cut the acquisition of the humvee to almost nothing, which had it gone through would have closed the factory. However during the week of March 8, a substantial portion of the funds were restored based on the fact that over time the factory would not be dependent on the DoD because AM General was in the process of implementing a plan to move out of the military business.

In terms of my earlier definitions, what we see at AM General is product diversification. But we also see a decision to do that product diversification in place enabled by the participation of the work force. In fact the work force has continued to be a major diving force behind improvements in quality, scheduling and changes in production equipment.

Something else in regards to DoD policy also happened at AM General. The Defense Department made it clear that they were willing to restore funds to AM General for continued production of the humvee at that facility because the firm had embarked on a process of diversification.

Principles of Conversion
From all of the above we arrive at some principles for conversion.

The objectives of any conversion plans needs to be to maintain/enhance the productive base of our country. An industrial or economic policy that seeks to enhance our productive base must be founded on a democratic decision-making system.

Thus the first principle that will enable sensible defense conversion must be democratic decision-making. What does democratic decision making mean? Affected communities and work force must be invited into some form of collective decision-making with the owners/operators of the facilities. Included in the scope of those decisions would be: product development--alternative use committees; process redesign--labor-management organizations empowered to make decisions; and content and organization of retraining programs.

A second principle is the concept of sustainable economic development. We want production for use, not for destruction, but we want to produce new products in such a fashion as to enhance the environment, not be more costly to it.

The Green Fuse: An Ecological Odyssey

John Harte

University of California Press, Berkeley, 1993, 156 pages

Physics, physicists are taught to believe, is superb training for many fields of endeavor. Among those who have demonstrated this truth in recent years, John Harte stands near the summit. Trained as a high energy theorist, he has become an ecologist of the highest order.

Almost a quarter century ago Harte and another physicist, Rob Socolow (now a Princeton professor and world leader in energy research), published Patient Earth (Holt Reinhart and Winston, New York, 1971), wherein they illustrated the disastrous impact of human technology on several sensitive ecosystems.

Harte's approach is eclectic and always elegant. He emphasizes common sense and careful matching of technique to problems. In 1985 he published Consider a Spherical Cow: A Course in Environmental Problem Solving (William Kaufman, Los Altos), a collection of worked ecological examples showing how to apply common sense and simple science to the natural world. Spherical Cow shows us that we have enough data in our heads to estimate the number of cobblers in the US, then moves to the rabbit populations in New Mexico on the basis of rabbit road kill observations, and far more. Choose your techniques carefully, Harte enjoins us; make your models no more complex than the question at hand demands. Nor simpler!

Spherical Cow is pure science. Green Fuse brings in the human dimension. Ecology becomes personal. Harte's use of "fuse" is intentionally ambiguous, referring both to the time bomb we have ignited by overpowering nature, and simultaneously to the linkages of the chain of life. The structure is a series of vignettes based on extensive travels and research. A nitrogen balance study of Southwest Alaska creeks and lakes segues into an explanation of the origin of Arctic haze, how radiocarbon dating shows the carbon is recent, and how haze may be affecting Arctic ice. A few chapters later a detective story of acidification in small lakes in the Colorado Rockies leads to the understanding of salamander population decline. The culprit is an acid pulse driven by an early spring runoff.

Harte shows us the elegant predictive power of simple models in scientific investigations, and why generalization can be risky. The action shifts to Tibet. The primary goal is to measure rain acidity in one of the most remote land locations in the world, but Harte finds time to explore humans and nature, the destructiveness of Chinese communism, and the down-side of synergy. Global warming is a recurring integrative theme, Harte's synecdoche for the panoply of humanity's ecological destruction.

In The Green Fuse John Harte demonstrates that he can not only do ecology, but communicate it too. Always precise, Harte has a sense of language and a taste for specificity that makes his examples come alive. Many of the examples bring in Berkeley graduate students, often appearing in the role of detectives to tease out nature's secrets. Knowing John Harte's personal preference for scientific objectivity, I wondered whether he would go beyond his sense of wonderment to describe his motivations and values. To my delight, he does: "Like many scientists, I feel awkward talking about myths and values because they cannot be analyzed with the tools in our kit bag. Nevertheless the often heard statement that science is value-free is arrant nonsense.

" Harte builds his ethos on the Golden Rule, raised to a higher level in the Kantian sense of the categorical imperative: "Adapt a rule governing how you deal with others as you would have them adopt a rule for dealing with you." To Harte the Golden Rule is broad indeed. It "encompasses people all over the planet, including those that may never see or know us." In his view, "others" includes "future generations that may be affected by our actions." But what have future generations done for us? Harte answers compellingly: "They can give us a reason for treating our ecological home respectfully, so that our lives as well as theirs will be enriched." They can give us "a vision that will plague our remaining days if we act so as to fulfill that vision by continuing to degrade our planet."

The "ecological odyssey" concludes, as it begins, with lines from Dylan Thomas:

"The force that through the green fuse drives the flower Drives my green age; that blasts the roots of trees Is my destroyer."

Though his examples are often discouraging, showing as they do massive adverse global effects of human activities, Harteremains optimistic. We still have time to change our ways--if onlywe have the will. If John Harte's eloquence and good science won't bring us to our senses, it's hard to see what will!

Inventing Accuracy: A Historical Sociology of Nuclear Missile Guidance

Donald MacKenzie

MIT Press, Cambridge MA, 1990

The cold-war superpower competition led to the development and deployment of advanced military technologies. A widely accepted wisdom has been that much of this arms race was driven by technological imperatives. Now that the superpower arms race has collapsed, it is appropriate to review this wisdom: Do technological imperatives really exist, and are they irresistable? We would like to know whether technological pressures might continue to generate arms races, and how we might control such pressures. Donald MacKenzie's Inventing Accuracy analyzes one technological imperative that may, or may not, have led to improving guidance systems for ballistic missiles, hence improving their accuracy.

MacKenzie poses the question in terms of "technological determinism" and "natural trajectories of technological change." Most of his text is devoted to reviewing the history of missile guidance, to see whether there was such determinism and trajectory in the evolution of missile accuracy. He describes several alternative technical approaches to improving missile accuracy, such as radio control, inertial guidance, and stellar guidance, and hediscusses which alternative was chosen and for what reasons. Clearly the accuracy of both ICBMs and SLBMs displays continuous improvements from 1945 on, with important contributions by miniaturization of electronic systems through transistors, integrated circuits, and microchips. But he goes far beyond reporting this progression intechnological capabilities. The strength of his book lies in the many interviews of participants in the development of missile guidance. These interviews allow him to examine the motivations of the technologists working on missile accuracy, such as Charles Stark Draper of MIT, and of the policy makers who decided which technologies to deploy.

The analysis of missile accuracy reveals deviations from technological determinism and natural trajectories; improvements in the accuracy of deployed missiles were not inevitable. It is true that once the U.S. Air Force accepted ICBMs as one of its responsibilities, it was very interested in improving accuracy for tactical or counterforce missions. And so, each generation of ICBMs had seemingly inevitable improvements in accuracy as supplied by Draper's Instrumentation Laboratory at MIT--in fact, the super-accurate guidance system for the MX ICBM existed even before the missile was ever chosen for development. However, the U.S. Navy saw its SLBMs as countervalue weapons, and actively opposed improved CEPs. None-the-less, SLBMs also increased in guidance capability: as their range was increased, new and more accurate guidance systems had to be built just to keep the targeting accuracy constant.

MacKenzie argues that missile guidance technology showed no natural trajectory. Indeed, there was competition between radio, inertial, stellar, and GPS guidance. There was competition between alternative approaches to building gyroscopes: suspension by liquid floatation, self-activated gas bearing, externally pressurized bearings, or electrostatics. Accelerometers could be restrained pendulums, pendulous integrating pendulums, or pulsed integrating pendulums. These technological arguments were often settled more by the force of personalities such as Draper than by technological competitions. Since the accuracy of ballistic missiles could have come through a variety of technological developments, it does indeed seem wrong to speak here of a natural trajectory of technological development.

MacKenzie agrees that the mature technology of inertial guidance shows "the continuous, predictable, apparently inexorable technological change that has so impressed those who have examined the growth of missile accuracy." But he argues that it should be seen "as an institutionalized pattern of predominantly incremental technological change involving, centrally, a self-fulfilling prophecy." He cites the history of ICBMs and SLBMs in detail to make the point that in the development of inertial guidance "changing people's perceptions and gathering resources.was at least as important.as writing equations and drawing blue prints." He argues that institutional controls on technological progressions should be seen as more than "artificial barriers to the natural course of technological change."

MacKenzie's arguments persuade that there has been no technological determinism or natural technological trajectory in the development of missile accuracy. But I believe his history is none-the-less consistent with the concept of technological imperatives. The fact, that improvements in missile accuracy could be achieved through several alternative technologies, does not contradict the argument that the great opportunity to improve missile accuracy (by whichever alternative method) exerted tremendous pressure to develop and deploy that improved accuracy. The fact that this pressure could be resisted in theory, and partially in fact by the U.S. Navy, means there is no determinism, there is no inevitability. But the more"sweet and beautiful" the technology, the harder it is to resist. This is demonstrated by the improvements in accuracy forced on the U.S. Navy for its SLBMs as these increased in range.

I accept that "missile accuracy is [not] a natural and inevitable consequence of technical change." Institutions can resist technological imperatives. But the more "sweet and beautiful" the technology is (as was the case for missile accuracy in the eyes of Draper), the harder it is to resist developing and adopting it. It is true that technologies such as missile accuracy "can be uninvented" in the sense of not deploying them. But this disinvention of a technology is easiest when an even sweeter technology takes its place, e.g., when the terminal guidanceof a warhead reduces the need for inertial guidance. Arms control, or technological restraint, must be an active barrier to those technologies that may not be completely inevitable, but which form a technological imperative.

A Question For Forum Members: What Should We Do About Our Contributed Paper Sessions?

In addition to its usual invited paper sessions at the April 1994 APS meeting, our Forum sponsored a contributed 10-minute-paper session that covered a range of topics unusually diverse for a single APS session. Attendance was small. Following the papers, we discussed whether or not such a Forum contributed session, in the standard format, should be held at future APS meetings. I write this to extend that discussion to other Forum members; we need your opinions on this matter.

The usual contributed paper session of an APS division is a group of experts gathered to discuss a very specific topic. When we wish to include non-experts in the play, and to give some background, we go to the extended time of an invited talk. A single 10 minute contribution usually represents a small advance or criticism of the subject and is based on a great body of expert knowledge and technique shared between speaker and audience. Listeners who aren't up-to-date in that shared knowledge usually find it hopeless to get anything from a talk. And yet our Forum contributed session ranged over diverse aspects of energy, environment, and arms control, from viewpoints that were phenomenological, theoretical, legal, political, and social.

Although speaker and listeners initially shared very little common information, yet in a mere ten minutes the speakers needed to bring the audience up to the topical front-line of the speaker. Speakers may have been able to share the "flavor" of their work, but certainly not enough insight was provided to provoke listeners' comment and criticism--the "payment" usually wanted for the effort involved in presenting the paper.

What to do? Cancel the sessions? But then we will not even be broadcasting the flavors, be less visible in the APS, and be of no service to those Forum members who seek recognition from their national organization in the face of the denial of professional validity by their home institutions. Keep the session as is? But then we are easily accused of dilettantism by our unsympathetic colleagues--a shelf of "flavors" is not physics! Change the format? Extend the contributions beyond ten minutes each? Make it possible for both background and forefront to be presented? Perhaps the session chair could negotiate a time with each speaker--10 minutes to 30 minutes. I am told that such changes in procedure are up to us--the APS meetings management will allow us considerable leeway. Shall we make use of it?

I invite your responses, either as communications to me or, better yet, as letters or comments to Physics and Society.

Trouble for Physics

Trouble for PhysicsIn its Spring 1994 issue, the journal Academic Questions carried an article entitled "The Natural Sciences: Trouble Ahead? Yes." It is a title that applies with even more force to physics than to the other natural sciences.

Authors Paul Gross and Norman Levitt (1) begin by quoting physicist and science historian Gerald Holton, who is concerned about anti-rationalism in Western society, and particularly with the growth of the academic anti-science "postmodernist" critique. According to Holton, "the argument made is that modern science has misled Western civilization badly. It provided false models such as the primacy of rationality and the search for objective truths... The search for objective truths in science was illusory in the first place, because all truths are only socially constructed fictions...This message, with avatars such as Michele Foucault and Jacques Derrida, has so repelled or bored scientists that hardly any have attempted an answer. At the very least, scientists...should pay more attention, avoid over-reaching in return, speak up against extreme nonsense... We must counter those expressions of the claustrophobia of the spirit; they wrongly assume the human situation requires an either/or choice." Holton writes that "History has shown repeatedly that a disaffection with science and its view of the world can turn into a rage that links up with far more sinister movements."

For Gross and Levitt, the problem lies partly with science education. They note the general science alienation among non-science undergraduates, and they chastise scientists for the fact that "A majority of students...never meet science in even remotely gratifying circumstances," and that "In gauging relativist claims that science is merely the ritualized belief-pattern of one transient culture, or eco-radical claims that science is the serpent of Eden, [students] have little countervailing experience beyond, perhaps, a painful passage-at-arms with freshman calculus or chemistry."

I agree. But I would add that we should too quickly dismiss the radical critiques of science that are surfacing more frequently these days. Scientists have, for example, contributed mightily to the specialization of knowledge that today threatens to tear even physics (itself a subfield) into noncommunicating branches called "particles," "condensed matter," and so forth. Partly because of an inappropriate aping of the scientific style, knowledge itself has fractured into disconnected specialties and the cry of students and others for educational "relevance" has become more than a little justified.

For another example, we have not taken much responsibility for the global threats that have arisen partly from the hands of the scientific and technological community, threats such as nuclear weapons and global warming. Postmodernists and scientists might argue over whether the scientific community is in some sense to blame for such threats, but there can be little argument over the fact that most scientists are doing little to educate their fellow citizens about such matters. Most of us go about our business of research in particles or condensed matter, we teach our narrowly-focused "pure" physics courses to "pure" science students and preferably to "pure" physics students, and we treat nuclear weapons and global warming and such as interesting topics for hallway discussion but hardly fit topics for serious introduction into our own daily work

. And for a third example (the one that Gross and Levitt write about), we ignore the anti-rationalism that is all around us. Although Gross and Levitt discuss primarily the postmodernist form of anti-rationalism, we also must contend with such pseudoscientific beliefs as creationism and astrology, and with emotionally-based religious and political belief systems that are at odds with most of what science stands for. The only long-term solution for such ills is thoughtful and broad science education, yet few of us concern ourselves with science education, preferring instead to fill the pages of The Physical Review with learned articles on particles and condensed matter.

Now, I certainly don't want to knock particle physics or condensed matter physics or any other special tree in the beautiful forest of physics, but I do want to raise the question of whether physics can prosper if so many of its practitioners pay attention only to their own individual tree, at the expense of the forest. At a time when the "unity" meeting of the American Physical Society, namely the April meeting, is failing for lack of interest and being incorporated into the March meeting which thus becomes the single remaining general meeting; at a time when APS retiring president Donald Langenberg's excellent address at the "Unity of Physics Day" gathering at the April meeting garnered a surprisingly (to me at any rate) small turnout; at a time when so few of our public school or college students learn any physics at all: Is it really so surprising that our Superconducting Supercollider collapses for lack of political support, and that many of us find ourselves out a job? A perceptive friend of mine, a physicist, remarked to me a couple of years ago that physics may be in the process of becoming, like Latin and Greek, a dead language. Perhaps so, I said at the time. Nothing I have seen since that time has changed this view.

The remedies are clear, but they are not easy, they will take time, and our research-oriented reward system is not appropriate for the task. My recommendations would include an hour of meaningful science education every school day of grades K through 12, more time and attention devoted by academic scientists to teaching nonscientists, tipping the research-versus-teaching balance away from its current overemphasis on research toward teaching as the first priority, a closer organizational relationship between physics research and physics teaching directed ultimately toward a joining of the APS with the American Association of Physics Teachers, a broader definition of "physics" to include more applied topics and to include neighboring areas of the other sciences and certain philosophical and societal topics such as scientific methodology and global warming, and greater dialogue with our colleagues in the humanities and other fields such as business and law. Briefly, we must humanize physics, and integrate it into the broader culture.

Trouble for physics? The answer will continue to be yes, unless we are open to the challenge of looking within ourselves for the cause of many of our own problems, and up to the task of redefining our view of physics and of the organizational structures that support it.
