The Pursuit of Beauty – Yitang Zhang solves a pure-math mystery

What an amazing article from the New Yorker about a fascinating man and a mathematical proof he found. It’s on the long side, but I was completely transfixed reading it.

Nearly 1/4th of Japanese college students missed this elementary school math question – what about you?

The multiple-choice question asked was this:

What can be inferred from a sentence stating that the average height of 100 students is 163.5 cm?

(1) The total height of the 100 students is 16,350 cm.

(2) Students whose height are around 163.5 cm form the largest group among the 100.

(3) The number of students taller or shorter than the average is the same.

What is your answer? And yes, I did get this right.
