Physics for Future Presidents

Why do president know physics? Perhaps then, what exactly is with physics associated with many problems with whom he will have to face? Or because physics today becomes the main science - the science that opens human doors to the future? We stand on the threshold of global warming - so what does it threaten our planet? What is a greenhouse effect? Is it possible to prevent the exhaustion of energy reserves? What is biological terrorism - and how to deal with him?
The President of the Great State has to face these and similar, important for all questions very, very often. How should they answer them? And do there be answers in general? About this writes in his book Richard A. Muller!
