TITLE: Books that develop interest & critical thinking among high school students
QUESTION [10 upvotes]: I heard about Yakov Perelman and his books. I just finished reading his two volumes of Physics for Entertainment. What a delightful read! What a splendid author. This is the exact book I've been searching for. I can use it to develop interest for science (math & physics) in my students.
His math books:

Mathematics Can Be Fun
Figures for Fun
Arithmetic for entertainment
Geometry for Entertainment
Lively Mathematics
Fun with Maths & Physics

His physics books:

Physics for Entertainment (1913)
Physics Everywhere
Mechanics for entertainment
Astronomy for entertainment
Tricks and Amusements

I want to get all the above books. Because books from author like this cannot be disappointing. But unfortunately not all of them are available. :(
I also read another amazing book How to Solve It: A New Aspect of Mathematical Method by G. Polya. This books actually teaches you how to think. 
In the similar lines if you have any book suggestions (with very practical problems & case studies) for physics & Math (Please don't differentiate between math & physics here. If I can develop interest in one of the subject he'll gain interest in other.) please contribute.

REPLY [2 votes]: As a kid I really enjoyed The Mathematical Tourist by Ivars Peterson (at the time, the 1988 edition).  The best part is that it gave just enough detail (for example, on how to compute a particular type of fractal) to inspire me to implement a computer program of my own to carry out the calculation or simulation.  In this way it really was a good guidebook for my own mathematical/computational explorations.
