Was I Feynman's student? No. Have I ever met him? No. Then why am I so crazy about Feynman?

According to Yuval Ne'eman, Feynman's two great contributions are Feynman diagrams and his parton picture of fast-moving hadrons. They solve many problems in physics. At the same time, he left us some homework problems.

These are challenging problems. I have been worrying about these two problems since 1970 after hearing his talk given at the April meeting of the American Physical Society held at Washington's Shoreham Hotel.
