Letter: Imagine that

Published 30 December 2014

From John Knutson

I thoroughly enjoyed Anil Ananthaswamy’s article on how to think about higher dimensions (13 December 2014, p 32).

I’m not a mathematician, but maybe extra dimensions are like imaginary numbers – not real, but necessary for things to work.
