Find out how a theory from physics has provided tools for solving long-standing problems in number theory. And in turn how number theory helps solve the mystery of black holes.
Entropy is the hero of our story – bringing together physics at every scale.
Tea gone cold? Don't worry, you can cheer yourself up with the theory of thermodynamics.
Is it about energy? Is it about disorder? Or is it about information? It's all three!
In memory of Stephen Hawking we look at the equation he was most proud of.
Fundamental physics says time is symmetric - so why does time move forwards for us in a block universe?
Our messy desk is proof of the second law of thermodynamics...
If I tell you something you already know, then that's not very informative. So perhaps information should be measured in terms of unexpectedness, or surprise?
Computers represent information using bits — that's 0s and 1s. It turns out that Claude Shannon's entropy, a measure of information invented long before computers became mainstream, measures the minimal number of bits you need to encode a piece of information.
