In the end, I'll always remain a scientist. I do love science; it might well be the greatest of the arts. Searching for truth, demanding of Nature that She is thinkable and comprehensible, demanding of oneself an absolute submission to reality, and all this in a process which creates incredible beauty. Science is a form of art, but the scientist is the hardest of all artists - he alone allows his creations to be discarded not merely as ugly by his fellow human beings, but also as false by reality itself.
