Discussions with people about how they envision physics and the world, got us talking about glasses. Here is a small collection of images of glasses sent to me by physicists. Each struck me as a kind of self portrait.
David Herrera Marti and his glasses which he keeps taking on and off
Sania Jevtic and her glasses of many different colours
Andrew Jaffe's glasses and an inflatable model of the cosmic background radiation - or 'big bang' as we 'see' it today
