Where do Mathematical Symbols Come From?

Where do we get our mathematical symbols from? Why is the set of integers called ℤ ? When was the equals sign first used? How about zero? Good notation tends to catch on quickly, whereas bad notation can obscure beautiful theory.

Space Sounds: The Music of the Cosmos

Space today is terrifyingly silent. But it wasn’t always thus: the early universe was filled with a hot plasma in which sound waves could travel. The cosmos was quivering with the aftershocks of the Big Bang.

Networks: The Internet and Beyond

Networks were seen as a rather arcane and dull area in computer science. Then along came the internet, and everything changed for ever.

Computers: A History

Even the most humdrum of electrical devices nowadays contains at least one computer; yet surprisingly few people are aware of their history, their form or function. In this talk we will see that not only is the history of computers rich and diverse, their architecture likewise.

Mathematical Structure in Fiction

Mathematical concepts have often been used to create new structural forms in fiction, as in the works of Raymond Queneau and Jorge Luis Borges.

Cosmic Vision: Fast & Furious

Highly energetic particles from outer space travelling at the speed of light, known as cosmic rays, originate from the sites of extreme particle acceleration in the Universe.

Mathematical Journeys into Fictional Worlds

Literary satire has long used mathematical concepts to reinforce its points.

Cosmic Vision: Unravelling Rainbows

When light is dispersed into its constituent colours, it can become possible to discern rich dynamical information about an evolving system in space, for example cosmic explosions, collisions or accelerations.

An Introduction to Programs

Niklaus Wirth said Algorithms + Data Structures = Programs. But programs are more than that. They are ubiquitous in modern life, but only a tiny minority of the population know how to program.

Neutrino: The Particle that Shouldn’t Exist

In 1930, the great physicist Wolfgang Pauli invented a new particle to save the principle of energy conservation in certain radioactive decays he was studying.
