As COP28, the 2023 United Nations Climate Change Conference, kicks off we look at how maths can help understand the climate crisis.

How do you create dramatic film out of mathematics? We find out with writer and director Timothy Lanzone.

Mathematics plays a central role in understanding how infectious diseases spread. This collection of articles looks at some basic concepts in epidemiology to help you understand this fascinating and important field, and set you up for further study.

Find out why the formula we use to work out conditional probabilities is true!

- We talk about a play that explores the fascinating mathematical collaboration between the mathematicians GH Hardy and Srinivasa Ramanujan.

1) Starting with arithmetics, whole mathematics must be founded in the continuum of geometry. Even Frege admitted that he had spent his whole life on the wild goose

chase, trying to found it in the discreteness of the Set Theory.

2) let's consider the famous Goedel sentence G: "This sentence is not provable" and the theorem: "G is true but not provable in the theory".

G is neither false,nor true for the simple reason that it is NO statement at all. By the standards of Goedell's own Predicate Logic a statement is a predication,

an assignment of a property to a subject. "Truth/Falsity" qualifies the predication itself and not the subject of predication. A statement "all cars are red" is a valid

predication or statement which may be true or false and by virtue of observations turns out to be false.

Now, G does not assign any property to any subject, thus is not a predication, not a statement at all, a meaningless chain of characters that may not be true or false.
