Want facts and want them fast? Our *Maths in a minute* series explores key mathematical concepts in just a few words. From symmetry to Euclid's axioms, and from binary numbers to the prosecutor's fallacy, learn some maths without too much effort.

Maths in a minute: Gradient descent algorithms

Whether you're lost on a mountainside, or training a neural network, you can rely on the gradient descent algorithm to show you the way!

Maths in a minute: Machine learning and neural networks

Machine learning makes many daily activities possible, but how does it work?

Maths in a Minute: Simplices – the atoms of topology

If you love triangles as much as we do, we have great news – you can have them in any dimension you want!

Maths in a minute: Artificial neurons

When trying to build an artificial intelligence, it makes sense to mimic the human brain. Artificial neurons do just that.

Maths in a minute: The Wells-Riley model

How do you calculate your risk of catching an airborne disease?

Maths in a Minute: Computational fluid dynamics

The mathematical equations governing fluid flow may have no known solutions, but maths still has the answers!

Maths in a minute: The positive predictive value

When you receive a positive test result for a disease, the chance you actually have it depends on how common the disease is.

Maths in a minute: Cyclic groups

When things go round and round, a cyclic group may be just what you need!

Maths in a minute: Representing groups

Groups occur all over mathematics, so it makes sense to find a common language to talk about them all.

Maths in a minute: Triangular numbers

Triangular numbers: find out what they are and why they are beautiful!
