Einstein's Relativity and the Quantum Revolution: Modern Physics for Non-Scientists \ Теория относительности Эйнштейна и "квантовая революция": современная физика для непрофессионалов- Страна: США
Год: 1995
Автор: Richard Wolfson \ Ричард Волфсон
Издательство: The Teaching Company
Язык: английский
Жанр: Лекции
Продолжительность: 24 лекции по 30 минут
Описание: Тем, кто готовится обучаться или стажироваться в американских или британских университетах, а также всем образованным людям (не только физикам или математикам, но и экономистам, историкам, теологам и лингвистам), интересующимся не только своей специальностью и английским языком, но также проблемами науки и научного мировоззрения, мы предоставляем ещё одну возможность попрактиковаться в восприятии на слух лекций научного и научно-популярного характера.На сей раз перед нами содержательный, хотя и "научно-популярный" курс проф. Ричарда Вольфсона, посвящённый разъяснению двух концепций, в начале XX века изменивших представления об устройстве мира: " Теория относительности Эйнштейна и "квантовая революция": современная физика для непрофессионалов".Во введении к курсу лекций о том, что, возможно, важнее всего во вселенной, проф. Вольфсон говорит: "Для того, чтобы понимать современную физику не надо быть Эйнштейном."
Теория относительности и квантовая механика изучают основы физического мира, изменяя наши, базирующиеся на "здравом смысле", представления о пространстве и времени, о причине и следствии. Считается, что обе эти теории чрезвычайно сложны. Это правда, но идеи, лежащие в основе как общей и специальной теории относительности, так и квантовой механики, по сути просты и доступны восприятию любого цивилизованного человека. Но с какой стати нам, неспециалистам, интересоваться этими знаменитыми теориями? Дело в том, что теория относительности и квантовая физика не только впечатляющи и прекрасны, они открывают нам врата к пониманию множества вещей, с которыми обычные люди сталкиваются в новостях - от путешествий в пространственно-временном континуме, до "теории струн", чёрных дыр, космических телескопов, ускорителей элементарных частиц и других понятий, находящихся на переднем крае науки. Первое издание аудиокурса было издано в теперь уже далёком 1995 г. В новом издании проф. Вольфсон решил уделить гораздо большее внимание философской интерпретации квантовой механики а также последним экспериментальным работам, подтверждающим обоснованность такой интерпретации. Добавлена заключительная лекция о так называемых "общих теориях всего" и об оценке возможности её создания на основе теории струн. Не пугайтесь незнакомых слов: этот курс лекций адресован не физикам, а профессионалам в любых иных областях человеческой деятельности. Впрочем физикам (изучающим английский язык) этот курс, безусловно, очень понравится. Они не найдут там ни грана вульгаризации, ибо автор - не просто талантливый популяризатор, а признанный физик-теоретик.

Описание на английском языке

"It doesn't take an Einstein to understand modern physics," says Professor Richard Wolfson at the outset of this course on what may be the most important subject in the universe.
Relativity and quantum physics touch the very basis of physical reality, altering our commonsense notions of space and time, cause and effect. Both have reputations for complexity. But the basic ideas behind relativity and quantum physics are, in fact, simple and comprehensible by anyone. As Professor Wolfson points out, the essence of relativity can be summed up in a single sentence: The laws of physics are the same for all observers in uniform motion.
The same goes for quantum theory, which is based on the principle that the "stuff " of the universe—matter and energy—is not infinitely divisible but comes in discrete chunks called "quanta."
Profound ... Beautiful ... Relevant
Why should you care about these landmark theories? Because relativity and quantum physics are not only profound and beautiful ideas in their own right, they are also the gateway to understanding many of the latest science stories in the media. These are the stories about time travel, string theory, black holes, space telescopes, particle accelerators, and other cutting-edge developments.
Consider these ideas:
Although Einstein's theory of general relativity dates from 1914, it has not been possible to test certain predictions until recently. The Hubble Space Telescope is providing some of the most striking confirmations of the theory, including certain evidence for the existence of black holes, objects that warp space and time so that not even light can escape. Also, the expansion of the universe predicted by the theory of general relativity is now a known rate.
General relativity also predicts an even weirder phenomenon called "wormholes" that offer shortcuts to remote reaches of time and space.
According to Einstein's theory of special relativity, two twins would age at different rates if one left on a high-speed journey to a distant star and then returned. This experiment has actually been done, not with twins, but with an atomic clock flown around the world. Another fascinating experiment confirming that time slows as speed increases comes from measuring muons at the top and bottom of mountains.
A seemingly absurd consequence of quantum mechanics, called "quantum tunneling," makes it possible for objects to materialize through impenetrable barriers. Quantum tunneling happens all the time on the subatomic scale and plays an important role in electronic devices and the nuclear processes that keep the sun shining.
Some predictions about the expansion of the universe were so odd that Einstein himself tried to rewrite the mathematics in order to eliminate them. When Hubble discovered the expansion of the universe, Einstein called the revisions the biggest mistake he had ever made.
An intriguing thought experiment called "Schrödinger's cat" suggests that a cat in an enclosed box is simultaneously alive and dead under experimental conditions involving quantum phenomena.
From Aristotle to the Theory of Everything
Professor Wolfson begins with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics. Then he outlines the logic that led to Einstein's theory of special relativity, and the simple yet far-reaching insight on which it rests.
With that insight in mind, you move on to consider Einstein's theory of general relativity and its interpretation of gravitation in terms of the curvature of space and time.
Professor Wolfson then shows how inquiry into matter at the atomic and subatomic scales led to quandaries that are resolved—or at least clarified—by quantum mechanics, a vision of physical reality so at odds with our experience that it nearly defies language.
Bringing relativity and quantum mechanics into the same picture leads to hypotheses about the origin, development, and possible futures of the entire universe, and the possibility that physics can produce a "theory of everything" to account for all aspects of the physical world.
Fascinating Incidents and Ideas
Along the way, you'll explore these fascinating incidents and ideas:
In the 1880s, Albert Michelson and Edward Morley conducted an experiment to determine the motion of the Earth relative to the ether, which was a supposedly imponderable substance pervading all of space. You'll learn about their experiment, its shocking result, and the resulting theoretical crisis.
In 1905, a young Swiss patent clerk named Albert Einstein resolved the crisis by discarding the ether concept and asserting the principle of relativity—that the laws of physics are the same for all observers in uniform motion.
Relativity implies that the time order of events can be different in different reference frames. Does this wreak havoc with cause and effect? And why does Einstein assert that nothing can go faster than light?
Shortly after publishing his 1905 paper on special relativity, Einstein realized that his theory required a fundamental equivalence between mass and energy, which he expressed in the equation E=mc2. Among other things, this famous formula means that the energy contained in a single raisin could power a large city for a whole day.
Historically, the path to general relativity followed Einstein's attempt to incorporate gravity into relativity theory, which led to his understanding of gravity not as a force, but as a local manifestation of geometry in curved spacetime.
Quantum theory places severe limits on our ability to observe nature at the atomic scale because it implies that the act of observation necessarily disturbs the thing that is being observed. The result is Werner Heisenberg's famous "uncertainty principle."
Are quarks, the particles that make up protons and neutrons, the truly elementary particles? What are the three fundamental forces that physicists identify as holding particles together? Could they be manifestations of a single, universal force?
A Teaching Legend
On his own Middlebury College campus, Professor Wolfson is a teaching legend with an infectious enthusiasm for his subject and a knack for conveying difficult concepts in a way that fosters true understanding. He is the author of an introductory text on physics, a contributor to the esteemed publication Scientific American, and a specialist in interpreting science for the nonspecialist.
In this course, Professor Wolfson uses extensive illustrations and diagrams to help bring to life the theories and concepts that he discusses. Thus we highly recommend our DVD version, although Professor Wolfson is mindful of our audio students and carefully describes visual materials throughout his lectures.
Professor Richard Wolfson on the Second Edition of Einstein's Relativity:
"The first version of this course was produced in 1995. In this new version, I have chosen to spend more time on the philosophical interpretation of quantum physics, and on recent experiments relevant to that interpretation. I have also added a final lecture on the theory of everything and its possible implementation through string theory. The graphic presentations for the DVD version have also been extensively revised and enhanced. But the goal remains the same: to present the key ideas of modern physics in a way that makes them clear to the interested layperson."

The Teaching Company

The Teaching Company was founded in 1990 by Thomas M. Rollins, former Chief Counsel of the United States Senate Committee on Labor and Human Resources.
Years earlier, as a Harvard Law School student, Rollins had an unforgettable experience that opened his eyes to the extraordinary power of a great lecturer captured on tape.
Rollins was facing an important exam in the Federal Rules of Evidence but was not well prepared. He managed to obtain videotapes of 10 one-hour lectures by a noted authority on the subject, Professor Irving Younger.
"I dreaded what seemed certain to be boring," Rollins says. "I thought that few subjects could be as dull as the Federal Rules of Evidence. But I had no other way out."
Rollins planted himself in front of the TV and played all 10 hours nearly non-stop. The lectures, he says, "were outrageously insightful, funny, and thorough." Watching Professor Younger's lectures was one of Rollins's best experiences as a student.
Rollins made an "A" in the course. And he never forgot the unique power of recorded lectures by a great teacher.
After many years of government service, Rollins founded The Teaching Company in 1990 to ignite people's passion for lifelong learning by offering great courses taught by great professors.
