About the Author

Leonard Susskind has been the Felix Bloch Professor in theoretical physics at Stanford University since 1978. The author of The Cosmic Landscape, he is a member of the National Academy of Science and the American Academy of Arts and Sciences, and the recipient of numerous prizes including the science writing prize of the American Institute of Physics for his Scientific American article on black holes. He lives in Palo Alto, California.

Reviews

Susskind (theoretical physics, Stanford Univ.) is widely regarded as the father of string theory. He applies the "diverse valleys" of that theory to our understanding of the universe but puts forth the "megaverse," of which our universe is only one small pocket. Susskind reviews a great deal of physics for the reader, from Feynman's diagrams to Einstein's theories of gravity and the cosmological constant to the Standard Model of Physics. While acknowledging the "uniqueness" and "elegance" of much of theoretical physics, Susskind suggests that the ultimate picture of the universe is more like an inelegant Rube Goldberg machine. The "Landscape" Susskind describes "is the space of possibilities-a schematic representation of all possible environments permitted by theory." Several chapters trace the development of string theory, and a final chapter visits the opinions of several contemporary physicists and cosmologists. Lively personal anecdotes from Susskind's career add color to his narrative. Offering an excellent overview of string theory and its potential for uniting "gravity with quantum mechanics," this work is recommended for science collections in academic and larger public libraries.-Garrett Eastman, Rowland Inst. at Harvard Univ.

As modern physics has developed a better understanding of how the universe operates at its most fundamental levels, one thing has become increasingly clear: we're damned lucky to be here at all. The laws of physics are precariously balanced, and were the value of one constant slightly different, life as we know it wouldn't exist. To explain the ridiculous improbability of it all, some physicists have turned to the "Anthropic Principle": the universe seems perfectly tailored to us because if it weren't, we wouldn't be here to observe it. The underlying rationale for this argument involves the "landscape" of potential laws of physics (which, it turns out, aren't so immutable after all), a whole bunch of extra dimensions and lots of particle physics. Luckily, Susskind-the father of string theory-does the job right, guiding readers through the current controversy over the Anthropic Principle. Make no mistake: this is the cutting edge of physics as described by one of the sharpest scientific minds around. While the subtitle is a bit misleading (this isn't about intelligent design in the Kansas Board of Education sense, but actually a controversy at once bigger and less prominent), persistent readers will finish this book understanding and caring about contemporary physics in ways both unexpected and gratifying.
