I heard about [Yakov Perelman][1] 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: 1. Mathematics Can Be Fun 2. Figures for Fun 3. Arithmetic for entertainment 4. Geometry for Entertainment 5. Lively Mathematics 6. Fun with Maths & Physics His physics books: 1. Physics for Entertainment (1913) 2. Physics Everywhere 3. Mechanics for entertainment 4. Astronomy for entertainment 5. 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][2]. 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. **Cross Post:** http://math.stackexchange.com/questions/10543/books-that-develop-interest-critical-thinking-among-high-school-students [1]: http://en.wikipedia.org/wiki/Yakov_Perelman#Books [2]: http://www.amazon.com/How-Solve-Mathematical-Princeton-Science/dp/069111966X
