What Biology can do for Physics
The physicist Stan Ulam once paraphrased Jack Kennedy and said: "Ask not what physics can do for biology, ask what biology can do for physics". This isn't a popular thing to say in the present climate of biotechnology and specifically targeted funding: is it possible that biology can actually teach us "new" physics? I won't succeed, but I will try to give some examples where I believe that biology does have something to give to physics. I am sure in the future this will become more the case, since I believe there are many mysteries in biology that we are far from understanding at a basic level because of a lack of physics understanding.
