But don't be misled into thinking this book is just for young people. It's for anyone who thirsts for knowledge and understanding, anyone who realizes that it doesn't require an alien life form to understand physics and math. Gamow discusses some of the great unsolved problems in mathematics (at least two of which - the four-color problem and Fermat's Last Theorem - have been solved since the book was written), the theory of relativity, the usefulness of imaginary numbers (square roots of negatives), geometry of more than three dimensions, and many other topics which most people think are accessible only to those anointed with stratospheric IQ's. But Gamow's writing is so clear and entertaining that you'll come away wondering why EVERYBODY doesn't understand those topics.
A particularly vivid memory I have of the book is Gamow's demonstration that there are different sizes of infinity.

Gamow was one of the greatest of 20th century physicists, and at the same time, a great teacher whose passion for the sheer fun of math and science was communicated in his books, whether explaining the wonders of infinite series, or how to locate a hidden pirate's treasure chest using imaginary numbers. Unlike a lot of modern poipular science writers, Gamow didn't shy away from showing you the math- but he could explain in a way that even an elementary school child could understand.
A wonderful book for the child or adult who isn't afraid to think.
It is of course inevitable, and no fault of the author, that portions have been overcome by events. For example, Fermat's Last Theorem has -- at long last -- been proven. So it is no longer true that (page 31) "no general proof ...has ever been achieved." Also, some of the material on elementary particles and genetics is dated.
To paraphrase Aristotle, nature abhors perfection, and so there are some errors as well. (I find this a bit surprising, since the book was revised in 1961, and I would expect these to have been caught.) For example, the discussion on complex numbers (page 37) contains a number of elementary errors - which however cancel, so the final result is correct! The periodic chart (page 136) shows gallium, indium and thallium as transition elements, whereas they are "main sequence" elements, of the boron-aluminum family. Also, the symbol for gallium is shown as Fa instead of Ga. Gamow's discussion of the drunkard's walk (page 200) has been over-simplified to the point where it is misleading. I mention these details because I think young and inexperienced readers may be unduly confused.

Since he never talks down, never hand-waves, and always goes straight to the essence of a topic, this decades-old book still seems fresh and contemporary. And yes, the dry, slightly pixilated humor still works.
I once met a man who had taken a course from Gamow at the University of Colorado. He said he would never forget the sight of the professor careening around campus in an open convertible -- in the middle of January!
