  • Finally, in the first quarter of the nineteenth century, and almost at the same time, a Hungarian and a Russian...Bolyai and Lobachevski...established irrefutably that a proof of Euclid's fifth postulate is impossible.

  • They did this by reasoning that if there were any way to reduce Euclid's postulate to other, surer axioms, another effect would also be noticeable: a reversal of Euclid's postulate would create logical contradictions in the geometry.

  • Thus by his failure to find any contradictions he proves that the fifth postulate is irreducible to simpler axioms.
    Part 3 (53% in)
  • A German named Riemann appeared with another unshakable system of geometry which throws overboard not only Euclid's postulate, but also the first axiom, which states that only one straight line can pass through two points.
