How is frequency related to pitch? Hear the music we love emerge from pure mathematical beats.

We talk to Stuart Johnston who uses mathematics to find out how noise pollution in the oceans impacts whales.

Generating electricity without the use of fossil fuels is not just an engineering and industrial challenge, it is also a huge mathematical challenge.

In this podcast author Coralie Colmez shares insights into her novel

*The irrational diary of Clara Valentine*.We talk to early career mathematicians who spent some of their summer holiday solving problems posed by industry — such as how to blend a perfect smoothie!

Firstly, many-worlds interpretation explains the problems of spooky action at a distance and perceived hidden variables perfectly adequately. In fact it is the most popular interpretation these days, not the misleading Copenhagen interpretation.

Secondly, his hypothesis seems to be saying 'either particles and us are non-deterministic' or 'particles and us are deterministic'. This is hardly a profound statement since we are made of particles. Using the phrase free-will seems to be deliberately trying to oversell the theory as something more important than it is. Free will is a very vauge term with many different definitions, so it doesn't serve to use this language other than to sensationalise.
