A short history of nearly everything.
It's heavy on the science and math but also includes some history and philosophy. What's great about it is it doesn't just tell you the world is 4 billion years old, it tells you how we know that and goes over the evolution of human thought and how we got to where we are today in each subject. It's also easy to read and the audio book version can be finished in a week of just listening to it during your commute.
Telling someone with no philosophy background to try to read 900 pages of Kant is a recipe for frustration.
