Two magnitudes whether commensurable or incommensurable, balance at distances reciprocally proportional to the magnitudes.

I am persuaded that this method [for calculating the volume of a sphere] will be of no little service to mathematics. For I foresee that once it is understood and established, it will be used to discover other theorems which have not yet occurred to me, by other mathematicians, now living or yet unborn.

Having been the discoverer of many splendid things, he is said to have asked his friends and relations that, after his death, they should place on his tomb a cylinder enclosing a sphere, writing on it the proportion of the containing solid to that which is contained.

Give me a place to stand, and a lever long enough, and I will move the world.

Eureka! (I have found it!).

Those who claim to discover everything but produce no proofs of the same may be confuted as having actually pretended to discover the impossible.
