Ramsey’s theorem predicts a surprising (and useful) consistency in the organization of graphs. Here’s a simple visual proof of how it works. Continue reading

Equiangular lines are an elemental part of geometry. Mathematicians have discovered a tighter limit on the number of such lines that exist in every dimension.

When a German retiree proved a famous long-standing mathematical conjecture, the response was underwhelming. Continue reading

In order to fully understand the quantum world, we may have to develop a new realm of mathematics. Continue reading

Each year, the 14th of March is celebrated by scientifically-minded folks for two good reasons. First, it’s Einstein’s birthday (happy 135th, Albert!). Second, it’s Pi Day, because 3/14 is the closest calendrical approximation we have to the decimal expansion of pi, π =3.1415927…. Continue reading

I LOVE PI. No, not pie. Pi. The number. This crazy number shows up in all sorts of weird places. If you take the square root of the gravitational field (*g *= 9.8 N/kg) you approximately get pi. Place a mass on a spring and let it oscillate? Yup, you get pi. Pi also one of the 5 super numbersin this magical equation: Continue reading
