Quick joke

What’s the difference between a PhD in math and a large pizza?

A pizza can feed a family of four.

Brain teaser

My friend just finished a job interview and was asked the following question that I thought I’d share with you (it’s a somewhat common puzzle):


You are given 8 balls, 7 of which are the same weight and 1 which is heavier than the rest. Using a balance, what is the minimum number of weightings required to determine which ball is the heavier one?

Mathematicians solve 140-year-old Boltzmann Equation

A couple of University of Pennsylvania mathematicians found solutions to some 140-year-old 7-dimensional equation. I guess solutions were not known to exist for
more than a century despite it being very popular in modeling the behavior
of gases.

The solution was found by Philip Gressman and Robert Strain and published in the Proceedings of the National Academy of Sciences. Strain says:

“We consider it remarkable that this equation, derived by Boltzmann and
Maxwell in 1867 and 1872, grants a fundamental example where a range of
geometric fractional derivatives occur in a physical model of the
natural world… The mathematical techniques needed to
study such phenomena were only developed in the modern era.”

Yay for math!

Math drinking games?

Saw this on Terry Tao’s blog, it’s a drinking game suggested by Mark Schnitzius that can promote mathematical thinking. Mark says:

“I was watching a travel show a while back — they were in Korea, and a group of people were playing a drinking game. The way it worked was, one person was “it”. This person says something like, “ready, set…” then points at one other player and calls out a number (call it x) between 2 and n (where n is the number of people playing). At the same time, everyone else also points at one other player. Then, for whatever number got call out, you jump that many steps from the “it” person, and that person has to drink. So if I call out “two” and point at Joe, and Joe points at Bob, then Bob has to drink.

I think the game is pretty interesting, mathematically, and could easily be adapted to be a game for kids. It’s especially interesting when you relax the x<=n rule. One interesting thing I found: with n=3, if you call x=7, you are guaranteed to stick the player you initially point at, no matter who points to whom.

Some interesting questions to ponder about it:

  1. Without the x<=n rule, what is the smallest number the ‘it’ person can call that guarantees he will not stick himself?
  2. With the x<=n rule in place, what is the safest number to call for any given n, if the other players choose randomly?
  3. If you’re TRYING to lose, what number should you call, both with and without the x<=n rule?
  4. What are the odds of winning or losing, for all the answers above?

Hint for questions 1 and 2: prime numbers come in to play!”

Another silly drinking game is below:

Here is an old music video for Johnathan Coultan’s song Mandelbrot Set (this is by Pisut Wisessing that was made in Film class at the Cornell Summer Animation Workshop). Enjoy!
