Someone who already knows about the subject and just wants equations he can't see.
There is no story -- at least for the first 30 minutes when I gave up. It's more like a math textbook, and that translates horribly to storytelling, especially for audio, when it requires looking at equations and mentions diagrams we can't see.
I don't know, but this narrator came off as pretentious which didn't help this subject.
These kinds of subjects -- quantum physics, relativity etc. -- can work but you have to tell a story. You can't get into equations and diagrams when you can't see them. For audio, you must tell a compelling story instead of just be a reference book.
Four similar books that know how to tell a story are: The Age of Entanglement, Quantum, Parallel Worlds, The Grand Design.
