From the transcript of the final debate:
WALLACE: Our national debt, as a share of the economy, our GDP, is now 77 percent. That’s the highest since just after World War II. But the nonpartisan Committee for a Responsible Federal Budget says, Secretary Clinton, under your plan, debt would rise to 86 percent of GDP over the next 10 years. Mr. Trump, under your plan, they say it would rise to 105 percent of GDP over the next 10 years.

There are quite a few movies which suggest that a mathematically-inclined mind makes you prone to depression. In fact, not that many famous mathematicians suffered crippling mental illness, apart from David Hilbert, Georg Cantor, Kurt Gödel, Alan Turing, Isaac Newton, Carl Gauss, Pierre de Fermat, Alexander Grothendieck, John Nash, Paul Erdös, Henri Poincaré, Bernhard Riemann, Joseph-Louis Lagrange, Évariste Galois, Ludwig Boltzmann, Marius Lie, Emil Post, Charles Babbage, Augustin Cauchy, Pierre-Simon Laplace, and Blaise Pascal…

I may not be much of a mathematician, but I have a favorite mathematician: Kurt Gödel.
At the beginning of the 20th Century, Bertrand Russell started an ambitious project. They would begin from basic principles of logic (truth, falsity and sets), and gradually derive the whole of modern mathematics. The work began to be published as a series of volumes named Principia Mathematica. After 379 pages, they’d gotten as far as conclusively proving that 1+1=2, so it looked as if they were well on the way to deriving integers, fractions, and so on.
