- Note for the scientists who sat for this project

The comments accompanying theses photos are divided in two parts. The first explains the image, the circumstances of my encounter with this scientist, or can be about an anecdote. The second, written by the scientist in person, describes his work.

If the text attached to your portrait does not include this second paragraph, I would appreciate it very much if you would take ten minutes of your time to briefly describe your work, in a language that any layman can understand. Thank you in advance.
