While the format of the past year and a half will mostly remain unchanged, VAMOS will move to a schedule of seminars every two weeks.  As before up-to-date schedule information as well as a link to register for the Zoom webinar and get the link is available at the VAMOS website.   You can attend the seminars live on Zoom or watch live or asynchronously later on the VAMOS YouTube channel.   The leadership committee would be happy if you would nominate a speaker for the series.

Starting this year there is a new VAMOS leadership committee:

The Quantum Reform of the International System of Units


The International System of Units (SI), the modern metric system, has recently undergone its most revolutionary change since the beginning of the metric system during the French Revolution.  The nature of this revolution is that all of the base units of the SI are now defined by fixing values of natural constants.  The realization of the units is now, both philosophically and practically, strongly quantum and specifically connected to AMO.  This talk will describe why this reform was needed and how it is done.
