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!

I rather like the fish tank analogy. When placed side by side Space would appear infinite but actually be quite finite. Observation only would be a poor predictor of size as that you would peer into other Universes without ever realizing there existed a barrier or that the other side of the other "Verse" had different properties much like a fish would feel outside of it's Universal tank and in Ours. Just a thought. However,this could also partly explain how particles such as photons could travel and bounce back and forth between as if no barriers existed in the first place.
