Space is three-dimensional ... or is it? When we spoke to
theoretical physicist David Berman in October this year we found
out that in fact, we are all used to living in a curved,
multidimensional universe. And a mathematical argument might
just explain how those higher dimensions are hidden from view.
Kaluza, Klein and their story of a fifth dimension — David
Berman explains the concept of dimension and how a mathematical
idea suggests that we might well live in five of them. The ten
dimensions of string theory — String theory has one very unique
consequence that no other theory of physics before has had: it
predicts the number of dimensions of space-time. David Berman
explains where these other dimensions might be hiding and how we
might observe them. How many dimensions are there? – the podcast
— You can listen to an interview with David Berman as he tells
us how Kaluza, Klein and their fifth dimension might help us
understand the ten dimensions of string theory.
