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: Category theory 
A quick introduction to an abstract concept that's useful in anything from genetics to cosmology.
Maths in a Minute: The wagon wheel effect 
Have you ever noticed the strange phenomenon of wheels appearing to move backwards while the vehicle is moving forwards? Aadit Jain explains why!
Maths in a minute: Semi-supervised machine learning 
Machine learning started with supervised learning and us providing all the training materials, but we are finding ways for algorithms to learn with far fewer resources.
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.
