Answers to questions in various scientific disciplines, e.g., "What are pulsars?", "Is the universe running down?", "What is the difference between a brain and a computer?", and "Why did the dinosaurs die off?".
No one explains science better than Isaac Asimov, to most he was a science fiction writer, but his greatest contribution to the world was in explaining science to others. In this book, he fields a series of 100 science questions and gives detailed answers, even though each is only two pages in length. Some of the questions are:
*) What are imaginary numbers? *) How many particles are there in the universe? *) Why do comets have tails? *) How will the Earth end? *) What is meant by curved space? *) What is the unified field theory? *) What's a breeder reactor? *) What is entropy?
As a source for quick and complete answers to many of the common questions about science, this book is unequaled.
