Why Aren't Black Holes Black?

I believe the sub-title for this book is quite fitting. R.M. Hazen and M. Singer aptly describe the major questions facing the physical sciences. This is not, however, a book for initiates of academia. It is written in a very simplistic manner, with a touch of humor intersperced within. I would describe it as a light read on a manner of subjects. If any of the articles arose your curiosity, ample suggestions for further reading are included in the back of the book. All-in-all, it was an enjoyable book suitable for a sunny afternoon read.

This is a wonderful book to read for anyone who enjoys science but doesn't have a science degree. This book explains questions many have pondered and it does it's best to give scientific explinations without making the reader feel as if he/she is inferrior to knowledge because they don't have a degree attached to their name. This book explains it in ways for everyone to understand, that I appreaciate.

Some have suggested that we will see the end of science when physicists eventually develop a grand unified theory. Robert M. Hazen and Maxine Singer disagree, and show that science is likely to be an ever-expanding sphere of inquiry and study far into the future. The book is clear, concise, and easy to read, with a thought-provoking introduction by Stephen Jay Gould. This is a great little book for airline flights, evenings before bedtime, or a sunny afternoon on the back deck.The book is non-technical, without a single equation (though some of us may find this a disadvantage). Subjects include cosmology, dark matter, the fate of the universe, energy, chemistry, symmetry, geology, biology, the origin of life, aging, evolution, genetics, human development, and the search for extraterrestrials. Each section in the book provides a summary discussion of the current state of knowledge. However, it frequently only hints at the big questions in science (though most ca! ! reful readers will be able to surmise them). In this, the book's content is somewhat different from the description given on the cover. Interestingly, the book never discusses why black holes are not black.Generally I found the book technically correct, though often abbreviated (something that would be hard to avoid, given the book's broad scope). Sometimes the abbreviated style leads to explanations that are potentially misleading. For example, the discussion of the second law of thermodynamics (see page 95) is only four paragraphs. In this short space the authors give several examples of the second law at work, concluding with the statement:"The second law defines the direction of events in time. Water flows downhill. Rooms get dusty. Supplies of fossil fuels diminish. We grow older."Given a correct understanding of other circumstances, the first two examples describe the second law. However, in each case we can find counter examples if we ignore the unmen! ! tioned conditions under which the second law applies. Wate! r will run uphill if pushed with an electric pump. Rooms can get less dusty if we clean them. Supplies of fossil fuels may renew over millions of years (and lots of energy from the sun). The problem with the presentation of these examples is that the book does not adequately describe the significance of spontaneous processes and the requirement for closed systems for which the second law applies. The second law of thermodynamics does not preclude open systems becoming more ordered, only that the overall disorder of any closed system must increase with time.The example of growing older is particularly susceptible to misleading conclusions. Aging is a poorly understood process that probably has a significant genetic component. At any rate, our bodies are not closed systems. We continually assimilate energy to drive our metabolic processes in order to stay alive. Consequently, using the aging process as an example of the second law of thermodynamics
