Maths in a minute
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: The prime number theorem 
A quick look at one of the most important theorems in number theory.
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.
