Alain Prochiantz, a professor in the Morphogenetics Department at the Collège de France, retraces the twists and turns – what he calls “accidents” – in his scientific career. One such “accident,” a major unexpected discovery, has redrawn the theoretical contours of his discipline and paved the way for new therapeutic approaches. Prochiantz speaks here as a scientist, but also as a philosopher of science and as an artist, all of which he feels are mutually complementary pursuits.
