In the late 18th century knowing the density of the Earth was a crucial, but missing, piece in a puzzle. Not only could that knowledge provide an insight in what was at the centre of the Earth, it could also provide the actual densities of every other body in the solar system – at this […]

You probably think of computers as being made of silicon chips. But in theory, you could also make a computer from billiard balls, streams of water or chains.
The simple question of ‘what time is it?’ started with a stick in the ground and is currently answered by closely observing the inner workings of caesium atoms.
Have you ever struggled to untie a particularly tight knot, battled with the jumbled mess of cables hidden behind your PC, or wondered why your shoelaces won’t stay tied? If so, you’re in good company, as mathematicians have wrestled with knots for over 200 years.
Dinosaurs are the largest animals to ever to walk the Earth. Nothing around on land today can compare to massive creatures like Diplodocus or Tyrannosaurus rex, though the water-dwelling blue whale dwarfs even the biggest prehistoric monster. People who study dinosaurs are called palaeontologists, and their work can sometimes be pretty tough – how do […]
Why is mathematics crucial to the design of the microwave?
The British 50p coin has a rather unusual shape. Like a circle, it has a fixed diameter, but clearly it isn’t as round as a circle. However, it is rounder than a regular heptagon, which has straight sides. So, just how round is it?
Down beneath everything we know lies another world. A world where nothing is forever, nothing is impossible, and nothing is certain.
Ada King, Countess of Lovelace, was the only legitimate child of romantic poet Byron. At 17, her remarkable maths abilities began to show.
Have you ever watched TV programmes like CSI or Bones and wondered how a real crime lab works? Forensic scientists use their knowledge of biology and chemistry to help police solve crimes, but they also need a solid understanding of maths. Investigative techniques such as DNA profiling and fingerprint identification rely on statistics and equations […]
The Large Hadron Collider is an ambitious project which hopes to find the smallest pieces that make up matter and study them.
The famous 20th century scientist Albert Einstein once said, ‘Education is that which remains when one has forgotten everything learned in school’. He meant that learning how to be inquisitive and think for yourself is more important than just memorising facts. That’s how Einstein discovered the theory of relativity – thinking hard about the maths of the universe.
