What does John Nash’s game theory equilibrium concept look like in Rock-Paper-Scissors?

A surprise discovery announced a month ago suggested that the early universe looked very different than previously believed. Initial theories that the discrepancy was due to dark matter have come under fire.

Paradoxically, a small galaxy that seems to contain none of the invisible stuff known as “dark matter” may help prove that it exists.

Using a brain-computer interface, scientists are beginning to learn why learning is hard.

A simple, step-by-step breakdown of two “perfect” math proofs.

Gravitational waves have opened up new ways to test the properties of black holes — and Einstein’s theory of gravity along with them.

For decades, researchers have commonly assumed that higher oxygen levels led to the sudden diversification of animal life 540 million years ago. But one iconoclast argues the opposite: that new animal behaviors raised oxygen levels and remade the environment.

Generations of researchers have pursued his “Langlands program,” which seeks to create a grand unified theory of mathematics.

The mathematicians Günter Ziegler and Martin Aigner have spent the past 20 years collecting some of the most beautiful proofs in mathematics.
