Who's Driving the Bus? 19Fairly recently, physicists decided that Bohr's description of the atom is wrong. I wondered if they were going to take back his Nobel prize, but then I found out Bohr is dead, and he already spent the money. The really amazing thing is that all the discoveries that were made by using a "wrong" model are still here. The Naugahyde chairs didn't disappear when physicists changed their minds. Physics is usually presented as a very "objective" science, but I notice that physics changes and the world stays the same, so there must be something subjective about physics.
