I am a physics nerd, with some 10 articles in educational journals and over 100 articles in more technical journals. My recent research has been in magnetism and spintronics, but on completion of two projects I would like to try to model viral load and infectivity, both within the body and within an enclosed room. I am married, with two adult daughters and two grandchildren. A year ago I had solar panels installed on my roof, and had a six tree mini-orchard planted in my backyard. I waste time, among other things, doing the Sunday NYT crossword puzzle and watching movies. Chernow's book on Grant lies only partially read because it was too depressing to read about how Andrew Johnson sabotaged Reconstruction and thereby encouraged criminal violence against Afro-Americans.
