The Grand Design

2018-08-06T15:37:00.004-07:00

THE FIRST MAJOR WORK IN NEARLY A DECADE BY ONE OF THE WORLD’S GREAT THINKERS—A MARVELOUSLY CONCISE BOOK WITH NEW ANSWERS TO THE ULTIMATE QUESTIONS OF LIFE When and how did the universe begin? Why are we here? Why is there something rather than nothing? What is the nature of reality? Why are the laws of nature so finely tuned as to allow for the existence of beings like ourselves? And, finally, is the apparent “grand design” of our universe evidence of a benevolent creator who set things in motion—or does science offer another explanation? The most fundamental questions about the origins of the universe and of life itself, once the province of philosophy, now occupy the territory where scientists, philosophers, and theologians meet—if only to disagree. In their new book, Stephen Hawking and Leonard Mlodinow present the most recent scientific thinking about the mysteries of the universe, in nontechnical language marked by both brilliance and simplicity. In The Grand Design they explain that according to quantum theory, the cosmos does not have just a single existence or history, but rather that every possible history of the universe exists simultaneously. When applied to the universe as a whole, this idea calls into question the very notion of cause and effect. But the “top-down” approach to cosmology that Hawking and Mlodinow describe would say that the fact that the past takes no definite form means that we create history by observing it, rather than that history creates us. The authors further explain that we ourselves are the product of quantum fluctuations in the very early universe, and show how quantum theory predicts the “multiverse”—the idea that ours is just one of many universes that appeared spontaneously out of nothing, each with different laws of nature. Along the way Hawking and Mlodinow question the conventional concept of reality, posing a “model-dependent” theory of reality as the best we can hope to find. And they conclude with a riveting assessment of M-theory, an explanation of the laws governing us and our universe that is currently the only viable candidate for a complete “theory of everything.” If confirmed, they write, it will be the unified theory that Einstein was looking for, and the ultimate triumph of human reason. A succinct, startling, and lavishly illustrated guide to discoveries that are altering our understanding and threatening some of our most cherished belief systems, The Grand Design is a book that will inform—and provoke—like no other.

Heisenberg's Quantum Mechanics

2018-08-04T10:21:00.003-07:00

This book provides a detailed account of quantum theory with a much greater emphasis on the Heisenberg equations of motion and the matrix method. No other texts have come close to discuss quantum theory in terms of depth of coverage. The book features a deeper treatment of the fundamental concepts such as the rules of constructing quantum mechanical operators and the classical-quantal correspondence; the exact and approximate methods based on the Heisenberg equations; the determinantal approach to the scattering theory and the LSZ reduction formalism where the latter method is used to obtain the transition matrix. The uncertainty relations for a number of different observables are derived and discussed. A comprehensive chapter on the quantization of systems with nonlocalized interaction is included. Exact solvable models, and approximate techniques for solution of realistic many-body problems are also considered. The book takes a unified look in the final chapter, examining the question of measurement in quantum theory, with an introduction to the Bell's inequalities.

SCIENTISTS JUST DISCOVERED A NEW HUMAN ORGAN, AND IT COULD HAVE HUGE IMPLICATIONS FOR HOW WE TREAT CANCER

2018-08-03T06:02:00.002-07:00

You would think, after thousands of years of study, we’d have nailed down what was going on inside us. But researchers are arguing that they have accidentally discovered an entirely new organ.

The new structure could even help explain where much of the fluid in our body sits, and may even be the source of lymph, the fluid that is essential to the functioning of our immune system. As such this network, or structure, of fluid-filled channels could be playing a significant role in maintaining our health, as well as propagating disease.

It’s not even limited to the obscure parts of us – it is found wrapped around many of our other, more well known, organs. You see, while we thought our lungs, digestive tract, and even our skin were surrounded by tough and dense connective tissue, it turns out that this tissue is in fact riddled with spaces supported through a meshwork of strong connective proteins to prevent them from collapsing, and which freely allow fluid to flow.

PROMISING CANCER “VACCINE” IS SET TO BEGIN HUMAN TRIALS

2018-08-01T05:46:00.000-07:00

An immune system-boosting cancer treatment that recently demonstrated astounding results in mice is now advancing to human testing.

Published less than two months ago in Science Translational Medicine, a study by Stanford University researchers showed that injection of two immune-stimulating agents directly into a tumor caused T-cells to recognize and destroy cancerous cells in both the local tumor as well as a distantly located secondary mass.

Because the combination treatment provokes an immune response and can be easily administered by an injection, the scientists have referred to it as a cancer “vaccine”, although technically speaking it is not a true vaccine.

Normally, T-cells are infective against tumors because the malignant cells within are either too similar to healthy cells to be recognized or the cancerous cells actually excrete chemicals that allow them to go undetected.

By identifying the structure of DNA, the molecule of life, Francis Crick and James Watson revolutionized biochemistry and won themselves a Nobel Prize. At the time, Watson was only twenty-four, a young scientist hungry to make his mark. His uncompromisingly honest account of the heady days of their thrilling sprint against other world-class researchers to solve one of sciences greatest mysteries gives a dazzlingly clear picture of a world of brilliant scientists with great gifts, very human ambitions, and bitter rivalries. With humility unspoiled by false modesty, Watson relates his and Cricks desperate efforts to beat Linus Pauling to the Holy Grail of life sciences, the identification of the basic building block of life. Never has a scientist been so truthful in capturing in words the flavor of his work.
