Maths in a minute: Correlation versus causation Wet cats don't cause umbrellas and umbrellas don't cause wet cats.

It's been raining outside and the cat came home wet. People are also carrying umbrellas. Which reminds us that #correlation isn't #causation plus.maths.org/content/math... #maths #mathematics #statistics

Intuitive mathematics Can a mathematical object be said to exist if you can't construct it?

#OTD in 1966 mathematician L.E.J. Brouwer passed away. Among other things he developed "intuitionism", an approach to #maths which rejects proofs by contradiction. It's fascinating! Find out more in this article plus.maths.org/content/intu... #philosophy #mathematics

Rob Eastaway: Shakespeare's mathematical life and times In this episode of Maths on the Move we talk to our friend Rob Eastaway about his book Much Ado About Numbers: Shakespeare's mathematical life and times.

But it turns out that there are physical phenomena which possess symmetries that group theory can't describe (for example certain types of phase transition). And it's here that you need to reach for category theory. We'll report more on this soon! #maths #math #physics

Groups: The basics Group theory is the mathematics of symmetry and structure. On this page, find out what a group is and how to think about them.

Symmetries are usually described by an area of #maths called group theory, quick intro here plus.maths.org/content/grou... #maths #physics

That's because the concept of #symmetry lies at the heart of #physics (see for example this article plus.maths.org/content/symm...) #maths #math
