"...physicists listen for the whispers from other universes"...but mainly to those from our own, January 24, 2010
Customer review from the Amazon Vine™ Program (What's this?)
This outstanding book reports on how cutting edge experimental physics is testing theories about dark energy, dark matter, inflation after the Big Bang, evidence of the Bang itself, multiverses, and the Higgs boson, to name a few. The author has trekked the globe to observe the various telescopes and particle colliders putting to the test the cosmological and quantum theories presently in vogue. Will string theory be verified? Will the graviton be found? Will better evidence confirm whether our universe's geometry is flat, saddle-shaped, or spherical?
To potentially answer such queries, The Edge of Physics: A Journey to Earth's Extremes to Unlock the Secrets of the Universe takes us first to Mount Wilson in California where "[t]he observatory [George] Hale built is called the birthplace of modern observational cosmology." Next, the author, journalist Anil Ananthaswamy, descends into the bowels of the Soudan Mine in Minnesota which now "hosts one of cosmology's most sensitive experiments: the Cryogenic Dark Matter Search (CDMS)." Among the other sites he visits are the Siberian neutrino telescope at Lake Baikal, another neutrino array telescope at the South Pole, an antimatter balloon experiment in Antarctica, and the European CERN Large Hadron Collider (LHC). Still another project isn't lashed to earth somewhere but has been sent out 900,000 miles into space. It's "the Planck satellite, the latest in a small but select group of pathbreaking space probes designed to map the cosmic microwave background." It was launched by the European Space Agency (ESA) in May, 2009. Of course, its scientists remain earthbound to monitor and analyze its anticipated wealth of relayed information.
Ananthaswamy skillfully integrates technical engineering details, clear background about the theories that might be verified and the human element. He interviews many of the people who brave often harsh, unforgiving climates and geography to build, operate, and interpret the minutely sensitive and calibrated instruments and their collected data.
In the epilogue Ananthaswamy journeys to Mount Saraswati in Tibet where the new Hanle Observatory is part of "an international collaboration called COSMOGRAIL (for COSmological MOnitoring of GRAvItational Lenses)." He notes there "I became aware of the deep silence enveloping me....It is abundantly clear, standing in Hanle, as it had been in places like the South Pole, Lake Baikal, Paranal, and the Karoo, that the natural calm of these places is what makes them ideal to cosmology. We need to protect them.... If we pollute them, we will destroy our best chance of deciphering our own beginnings, of understanding ourselves." Finding suitably remote, unspoiled locations on earth constantly becomes more difficult, but as THE EDGE OF PHYSICS so compellingly relates, we can still learn a great deal from telescopes and other instruments deployed here if we don't despoil the remaining wilds where they can be maximally effective.
This is a superb resource for anyone who eager learn about the current state of experimental physics, the technology required to carry out the research, the geography that best sustains various projects, the theories being tested, and the men and women who are on the front lines constantly evaluating, innovating, and stretching the boundaries of our knowledge about the cosmos.

A book that will make you stand up cheer, March 15, 2010
The legendary advertisement that was supposed to have been placed in a London newspaper by Sir Ernest Shackleton reads: MEN WANTED: FOR HAZARDOUS JOURNEY. SMALL WAGES, BITTER COLD, LONG MONTHS OF COMPLETE DARKNESS, CONSTANT DANGER, SAFE RETURN DOUBTFUL. HONOUR AND RECOGNITION IN CASE OF SUCCESS. Whether true or not, it is this spirit that animates the physicists who strive to discover the secrets of our universe at some of the most inhospitable places on Earth, under harrowing conditions that would give pause to the most intrepid explorer. Anil Ananthaswamy follows them and provides us with a window into their world. The result is a fascinating book which frames the tenets of Physics in a manner that is accessible to practically anyone. More importantly, it frames those eternal questions that have piqued the interest of mankind since the development of cognizance: Why are we here? Where did we come from? What lies outside the Universe, are there any other "heres"? The questions themselves awaken a sense of awe, but it is even more interesting to look into the lives of those who did not stop there, but decided to do something about it. From the Fraunhofer lines in stellar spectra to Digital Optical Modules embedded in a cubic kilometer of ice beneath the Earth's South Pole, to the coldest place in the known universe (which, oddly enough, is in a tunnel underneath Geneva), it is heartening to hear the stories of seemingly ordinary people who are striving to do extraordinary things. The result is a stirring, awe-inspiring good read, which has a definite tendency to make you want to stand up and cheer. Luckily for me, this could be accomplished with the minimum of fuss from my favorite armchair.
April 15, 2010: Some reviewers have made a note of the fact that the book does not have any high-quality pictures. To access additional content, pictures, videos and other details can be found at the web site for this book, [..] plus the author's blog on his travels to remote parts of the planet. Check it out!

A Potent Combination, January 17, 2010
Customer review from the Amazon Vine™ Program (What's this?)
For years, physicists have been trying to unify the four (known) fundamental forces of nature: gravity, strong nuclear, weak nuclear and electromagnetic. In this book, the author attempts to tie together work being done in ten different locations across six continents, each of which may provide a piece to the puzzle. Dark matter/energy, the multiverse, string theory and other topics make an appearance; if your goal is to get a deep understanding of any of them, this is not the book for you. However, if the story behind the science, coupled with a history and sense of place plus a gentle introduction to physics involved is your goal, then this is the book you're looking for.
In each chapter, the author details:
- why a particular location was chosen e.g. very little radiation/cosmic rays reach the depth of the Soudan Mine.
- how the instruments at each location are constructed e.g. "drilling" holes at the South Pole with hot water
- what the instruments are doing e.g. detecting neutrinos coming from the center of our galaxy
- why the experiments are important e.g. trying to determine whether our universe is flat or has a negative/positive curvature
In addition, he provides a window into the extraordinary lives of the people building the instruments/running the experiments/analysing the results, people who have devoted years of their lives and/or endure extreme conditions in the pursuit of science. He also sprinkles a number of non-scientific stories and facts about the locations themselves (Lake Baikal has a surprise at the bottom of it courtesy of the Russo-Japanese War) into the mix.
While the chapters can feel a bit long winded and repetitive at times, the book as a whole provides an engaging, enlightening read, a great springboard, should you desire, from which to explore the science, the places and/or the history in more depth.
