Nit-pick: "Theorems that have withstood the test of time are falling, one by one; just ask Fermat and Poincaré." The author means "conjectures", or "open problems" rather than "theorems". Theorems are the end-product of mathematics and do not fall one by one (unless someone finds a mistake in a proof, and a counterexample, which is pretty rare).
