The history of the chemical bond. When discussing the history of chemistry it’s always dangerous to point to the specific origin of an idea, since by its very definition, the scientific process relies upon the gradual refinement of ideas that came before.

Gravity is such a pesky thing. It prevents us from doing all sorts of wonderful things. Such as floating through the air like a balloon, traveling into orbit without paying an ugly cost in delta V, and being morbidly obese but still light on your feet like Baron Vladimir Harkonnen. By the same token, it would also be incredibly useful to be able to create gravity on command.
