How To Make An Apple Pie From Scratch is a popular science book about physics. Sounds like a dry read I know but it's one of the most upbeat and fascinating books about science I've ever read. Concepts I never thought I'd be able to grasp were easily explained...sometimes to the point where you're in danger of having an existential crisis when you realise how very fragile the entirety of existence is.

The author works for CERN on one of the experiments at the LHC so he knows his stuff and he's an excellent communicator of ideas without dumbing it all down in the slightest.

If you enjoyed Bill Bryson's 'Short History Of Everything' you'll enjoy this too.
