Mathematical models predict how fast a rumour will spread and how many people it's likely to reach.

What would happen if the Sun suddenly exploded? Einstein wondered the same thing, and completely changed our understanding of the Universe.

Mapping the ancestral history of spacetime in an effort to unite quantum mechanics and general relativity.

A model of backward causation in which the future affects the past could help unite quantum mechanics and general relativity – and satisfy a challenge thrown down almost a century ago by Arthur Eddington.

A new model argues the forces between particles in the early universe loosed time’s arrow, creating temporal order from chaos.

Euler may not have cracked this problem completely, but it led to a lot of important work, including on what we today know as sudoku.

This problem about an infinite sum has a surprising answer.

Can you find a path through on this city map that crosses every bridge exactly once? Euler's answer to this problem started off the filed of graph theory.
