I expect I’ll e-mail David Chandler when I get the chance, but in videos Richard Gage seems angry and unpleasant to me, and I think I’d have trouble maintaining the conversation. Chandler, in contrast, seems very calm and rational.
Regarding maths, nothing more complicated than multiplication and division is required, and even those don’t need to be accurate because most of the margins are huge. The main thing is to have paper for sketching the structure, so you can visualise what happened.
Thanks for your kind wishes. Do come and visit some of the sites; the atmosphere of calm, peaceful determination is incredible. The activists are all sorts of people, from science academics to Christians to shamans. There’s free food and hot drinks (voluntary contributions), and public performance of music, art and poetry. Love is the theme of the site I’ll be on, behind Downing Street.
