## philosophy of mathematics

Do we live in a matrix? What does physics tell us about reality? Are reality and information one and the same? Do things only exist if they are perceived? Find out some the answers to these fascinating questions.

How understanding why something is impossible can often lead to deeper understanding, contemplations of philosophy and even new mathematics.

What are mathematical proofs, why do we need them and what can they say about sheep?

Books, brains, computers — information comes in many guises. But what exactly *is* information?

*is*itself a mathematical structure. Does his claim stand up to scrutiny?

Are number, space and time features of the outside world or a result of the brain circuitry we have developed to live in it? Some interesting parallels between modern neuroscience and the mathematics of 19th century mathematician Bernard Riemann.

On the face of it the Universe is a fairly complex place. But could mathematics ultimately lead to a simple description of it? In fact, should simplicity be a defining feature of a "theory of everything"? We ponder the answers.

In this, the second part of this series, we look at a mathematical notion of complexity and wonder whether the Universe is just too complex for our tiny little minds to understand.
