“Take this neat little equation here. It tells me all the ways an electron can make itself comfortable in or around an atom. That's the logic of it.

And a million other things besides, about the way nature works.” NatureMathematicsPhysicsFine Structure ConstantConstants Of NatureFeynman Book:The Quotable Feynman Source: The Quotable Feynman

In fact,mathematics is, to a large extent, invention of better notations.” ScienceMathematicsMathsNotation Book:The Feynman Lectures on Physics Vol 1 Source: The Feynman Lectures on Physics Vol 1
