One
of Einstein's
greatest inspirations, as he later recalled, occurred during a
flash of insight in 1907: «For an observer falling freely from the roof
of a house there exists — at least in his immediate surroundings — no gravitational field.»
I did this without prior knowledge or checking, not through some
great flash of critical
insight, but because
of a family resemblance that anyone could recognize: «Life
of the Party» is a little too much like «Tammy.»
