I found the lead-in fascinating, the "search of fundamental laws". I have to admit that the first paragraph wasn't about that directly, but I also found it intriguing ("allergic to food", heh) - probably because I identify with the absent-minded professor portrayed (or would like to).

The "lead" of a story is partly a matter of perspective. Eg. did Einstein reveal a deeper view of reality, or facilitate nuclear weapons, or help end a war, or prove everyone wrong, or get away with crazy hair? The "lead" depends on the reader.
