### This Week’s Finds in Mathematical Physics (Week 277)

#### Posted by John Baez

In week277 of This Week’s Finds, find out what’s a million times thinner than paper, stronger than diamond, a better conductor than copper, and absorbs exactly

π α $\sim 3.14159 / 137.035 \sim 2.29254\%$

of the light you shine through it.

It turns out that bilayer graphene is better suited for computers because it creates a significant gap at ambient temperature, that one can tune, thus making it possible to make a transistor.
