A Brief History of Time by Hawking

  • Nov 19, 2003
The author ponders some very deep questions in theoretical and
practical physics and the universe. He covers space, time,
the expanding universe, uncertainty, black holes and a unifying
theory of physics and all matter. Einstein first postulated that
matter could neither be created nor destroyed. Ptolemy's model
predicts positioning of heavenly bodies. Galileo proved that
each body increased speed at the same weight despite it's own
weight except for a feather which fell slower due to air
resistance. The author explained that it takes 8 minutes for
light to reach the earth from the sun. In fact, this distance
is an important portal in the quantification and measurement
of time. Without light and distance, the measurement of time
would be difficult and perhaps impossible. The author explained
that the expanding universe slows down and stops.
Chandrasekhar calculated that a cold star would not be able
to support itself against its own gravity. This work is
excellent for science enthusiasts. It would be perfect for a
student class project in science.

Universally hailed as the greatest theoretical physicist since Einstein, Dr. Hawking serves as both an intellectual and physical inspiration. His disability - Lou Gehrig's disease- serves to make his every endeavor a slow and tedious affair, and yet his professional output remains very high, both in quality and quantity. This book is no exception.   Written at the level of the layperson, it is clear, concise, and through. As the title suggests, he begins with the origin of the universe …

. . .to the science of cosmology. Please note that I don't fault the depth of the book at all, Dr. Hawking has done his best to remove the mathematics and esoteric theorizing. Nevertheless, unless the reader has a prior basic knowledge of astronomy or cosmology, it's easy to get lost.Dr. Hawking is arguably one of the three greatest physicists of the last 500 years (Newton and Einstein being the others). In this book, he has skillfully attempted to bridge the gap between the world of the highly …

About this book


Stephen Hawking, one of the most brilliant theoretical physicists in history, wrote the modern classicA Brief History of Timeto help nonscientists understand the questions being asked by scientists today: Where did the universe come from? How and why did it begin? Will it come to an end, and if so, how? Hawking attempts to reveal these questions (and where we're looking for answers) using a minimum of technical jargon. Among the topics gracefully covered are gravity, black holes, the Big Bang, the nature of time, and physicists' search for a grand unifying theory. This isdeepscience; these concepts are so vast (or so tiny) as to cause vertigo while reading, and one can't help but marvel at Hawking's ability to synthesize this difficult subject for people not used to thinking about things like alternate dimensions. The journey is certainly worth taking, for, as Hawking says, the reward of understanding the universe may be a glimpse of "the mind of God."--Therese Littleton--This text refers to theHardcoveredition.
