Geometry:
“In our approach to geometry we thought it would be simpler to start with plane geometry; and it was supposed to be very complicated when you get to solid geometry and much more so when you get to spherical. So I gradually began to reverse my field, in order to get the total experience, and decided that spherical was much easier than solid, and the solid easier than the plane, so that everything became much simpler merely if I really started with the totality all the time and dealt-- in spherical geometry-- with the vectors.”
