(via http://danamackenzie.com)

 

On today’s episode of Strongly Connected Components Samuel Hansen rings up the recipient of the 2012 Joint Policy Board for Mathematics Communications Award, Dana Mackenzie. He speaks with the author about stealth mathematics, the generalism he has been allowed by journalism, and why using equations in your articles and books may not be such a bad thing. You can find out more about Dana Mackenzie by visiting his website, and be sure to check out his new book, out this year on Princeton University Press, The Universe in Zero Words.

Do You Know Your Methods of Proof

As a mathematician it is always important to know all the tools in your proof arsenal, and therefore The 36 Methods of Mathematical Proof is an indispensable guide for anyone who does any work in the field. Some of the methods include:

  • Proof by hasty generalization: “Well, it works for 17, so it works for all reals.”
  • Proof by deception: “Now everyone turn their backs…”
  • Proof by supplication: “Oh please, let it be true.”
  • Proof by poor analogy: “Well, it’s just like…”
  • Proof by avoidance: Limit of proof by postponement as it approaches infinity
  • Proof by design: If it’s not true in today’s math, invent a new system in which it is.
  • Proof by authority: “Well, Don Knuth says it’s true, so it must be!”
  • Proof by intuition: “I have this gut feeling.”
