There are limits to how much you can simultaneously squeeze the quantum fuzziness of an electron's position and momentum

Resonant electromagnetic waves, created by lightning flashes, circle the Earth. Wim Hordijk explores the maths and shows how you can keep track with these phenomena.

We take the real numbers for granted, but what are they really?

Take a quick trip to the foundations of probability theory.

Need to find the least common multiple or greatest common divisor of two numbers? A billiard table of the right proportions holds the answers!

Randomness is surprisingly hard to define. Fortunately the mathematical language we use to describe it is beautifully well defined.

The second guiding principle in probability theory is more subtle – universality.
