Physicists From The United States

"[Capra for instance, uses the term "Paradigm" to mean] the totality of thoughts, perceptions, and values that form a particular vision of reality, a vision that is the basis of the way a society organizes itself"

"The term "paradigm," from the Greek paradeigma ("pattern"), was used by Kuhn to denote a conceptual framework shared by a community of scientists and providing them with model problems and solutions"

"While the new physics was developing in the 20th century, the mechanistic Cartesian world view and the principles of Newtonian physics maintained their strong influence on Western scientific thinking, and even today many scientists still hold to the mechanistic paradigm, although physicists themselves have gone beyond it. However, the new conception of the universe that has emerged from modern physics does not mean that Newtonian physics is wrong, or that quantum theory, or relativity theory, is right. Modern science has come to realize that all scientific theories are approximations to the true nature of reality; and that each theory is valid for a certain range of phenomena."

"At the subatomic level, matter does not exist with certainty at definite places, but rather shows "tendencies to exist," and atomic events do not occur with certainty at definite times and in definite ways, but rather show "tendencies to occur.""

"As Eastern thought has begun to interest a significant number of people, and meditation is no longer viewed with ridicule or suspicion, mysticism is being taken seriously even within the scientific community An increasing number of scientists are aware that mystical thought provides a consistent and relevant philosophical back ground to the theories of Contemporary science, a conception of the world in which the scientific discoveries of men and women can be in perfect harmony with their SpirItual aims and religious beliefs."

"In biology the Cartesian view of living organisms as machines, constructed from separate parts, still provides the dominant conceptual framework. Although Descartes' simple mechanistic biology could not be carried very far and had to be modified considerably during the subsequent three hundred years, the belief that all aspects of living organisms can be understood by reducing them to their smallest constituents, and by studying the mechanisms through which these interact, lies at the very basis of most contemporary biological thinking. This passage from a current textbook on modern biology is a clear expression of the reductionist credo: 'One of the acid tests of understanding an object is the ability to put it together from its component parts. Ultimately, molecular biologists will attempt to subject their understanding of cell structure and function to this sort of test by trying to synthesize a cell."

"At the beginning of the last two decades of our century, we find ourselves in a state of profound, world-wide crisis. It is a complex, multi-dimensional crisis whose facets touch every aspect of our lives – our health and livelihood, the quality of our environment and our social relationships, our economy, technology, and politics. It is a crisis of intellectual, moral, and spiritual dimensions; a crisis of a scale and urgency unprecedented in recorded human history. For the first time we have to face the very real threat of extinction of the human race and of all life on this planet."

"What we need, then, is a new 'paradigm' – a new vision of reality; a fundamental change in our thoughts, perceptions, and values. The beginnings of this change, of the shift from the mechanistic to the holistic conception of reality, are already visible in all fields and are likely to dominate the present decade. The various manifestations and implications of this 'paradigm shift' are the subject of this book. The sixties and seventies have generated a whole series of social movements that all seem to go in the same direction, emphasizing different aspects of the new vision of reality. So far, most of these movements still operate separately and have not yet recognized how their intentions interrelate. The purpose of this book is to provide a coherent conceptual framework that will help them recognize the communality of their aims. Once this happens, we can expect the various movements to flow together and form a powerful force for social change. The gravity and global extent of our current crisis indicate that this change is likely to result in a transformation of unprecedented dimensions, a turning point for the planet as a whole."

"Fire made us human, fossil fuels made us modern, but now we need a new fire that make us safe,healthy, and durable. 2006-5-12"

"The markets make a good servant but a bad master, and a worse religion"

"When asked if we have enough time to prevent catastrophe, she'd always say that we have exactly enough time -- starting now"

"Variable but forecastable renewables (wind and solar cells) are very reliable when integrated with each other, existing supplies and demand. For example, three German states were more than 30 percent wind-powered in 2007—and more than 100 percent in some months. Mostly renewable power generally needs less backup than utilities already bought to combat big coal and nuclear plants' intermittence."

"A widely heralded view holds that nuclear power is experiencing a dramatic worldwide revival and vibrant growth, because it’s competitive, necessary, reliable, secure, and vital for fuel security and climate protection. That’s all false. In fact, nuclear power is continuing its decades-long collapse in the global marketplace because it’s grossly uncompetitive, unneeded, and obsolete—so hopelessly uneconomic that one needn’t debate whether it’s clean and safe; it weakens electric reliability and national security; and it worsens climate change compared with devoting the same money and time to more effective options."

"There are two kinds of micropower. One is co-gen and combined heat and power. That was about two-thirds of the new capacity and three-quarters of the new electricity last year. The rest was distributed or decentralized renewables, which was a $38 billion U.S. global market last year for selling equipment. That's wind, solar, geothermal, small hydro and biomass.... Micropower surpassed nuclear power in worldwide installed capacity in 2002, and surpassed nuclear in electricity generated per year just in the last few months."

"...new nuclear plants are simply unfinanceable in the private capital market, and the technology will continue to die of an incurable attack of market forces—all the faster in competitive markets. This is true not just in the U.S., where the last order was in 1978 and all orders since 1973 were cancelled, but globally."

"If you ask me, it'd be little short of disastrous for us to discover a source of clean, cheap, abundant energy because of what we would do with it."

"Facts are more mundane than fantasies, but a better basis for conclusions."

"People did not always love the mountains. Just a few hundred years ago the high mountains were regarded as horrible, monstrous places filling people with terror and fear. The inhabitants near them were seen as awful demons, subhumans. But this attitude got transformed into just the opposite, especially by Romantic writers and painters in the nineteenth century. Seen by the Romantics, high mountains became places of impossible beauty, where the quality of light and the expansive solitary grandeur of the high peaks opened the heart of the individual. A man climbing a mountain became the image of self-conscious intelligence pitted against the eternal indifference of the forces of nature. Compared to these forces of nature, we are nothing save for the will that moves our limbs. Only that will is truly our own."

"We surely stand at the threshold of a great adventure of the human spirit — a new synthesis of knowledge, a potential integration of art and science, a deeper grasp of human psychology, a deepening of the symbolic representations of our existence and feelings as given in religion and culture, the formation of an international order based on cooperation and nonviolent competition. It seems not too much to hope for these things. The future, as always, belongs to the dreamers."

"Although the idea that the universe has an order that is governed by natural laws that are not immediately apparent to the senses is very ancient, it is only in the last three hundred years that we have discovered a method for uncovering that hidden order — the scientific-experimental method. So powerful is this method that virtually everything scientists know about the natural world comes from it. What they find is that the architecture of the universe is indeed built according to invisible universal rules, what I call the cosmic code — the building code of the Demiurge. Examples of this universal building code are the quantum and relativity theory, the laws of chemical combination and molecular structure, the rules that govern protein synthesis and how organisms are made, to name but a few. Scientists in discovering this code are deciphering the Demiurge's hidden message, the tricks he used in creating the universe. No human mind could have arranged for any message so flawlessly coherent, so strangely imaginative, and sometimes downright bizarre. It must be the work of an Alien Intelligence!"

"Perhaps our thinking exemplifies a selective system. First lots of random scattered ideas compete for survival. Then comes the selection for what works best — one idea dominates, and this is followed by its amplification. Perhaps the moral [...] is that you never learn anything unless you are willing to take a risk and tolerate a little randomness in your life."

"Mountain climbing is an analogue of the research process in theoretical physics. In working on a problem in physics one is never assured of a solution, because there are many false leads and pitfalls. Likewise in climbing there is no certainty of attaining the summit; the route is often unknown, or sometimes one attains a false summit. But the important point is that if you reach the top, the view is enormous. There is no comparison between what you see from just below the summit and what you can see from the top. Similarly with finally solving an important problem in physics the view you get is enormous."

"Most physicists enjoy the outdoors. They are mushroom gatherers, bird watchers, hikers, amateur mountaineers whose idea of weekend relaxation is to climb a mountain. Several physics summer schools and research centers are located in or near mountainous areas. I have not seen such uniform recreational impulses in other professions, an observation which prompts speculation on the connection between the nature of inquiry in physics and mountain climbing."

"I often dream about falling. Such dreams are commonplace to the ambitious or those who climb mountains. Lately I dreamed I was clutching at the face of a rock but it would not hold. Gravel gave way. I grasped for a shrub, but it pulled loose, and in cold terror I fell into the abyss. Suddenly I realized that my fall was relative; there was no bottom and no end. A feeling of pleasure overcame me. I realized that what I embody, the principle of life, cannot be destroyed. It is written into the cosmic code, the order of the universe. As I continued to fall in the dark void, embraced by the vault of the heavens, I sang to the beauty of the stars and made my peace with the darkness."

"I used to climb mountains in snow and ice, hanging onto the sides of great rocks. I was describing one of my adventures to an older friend once, and when I had finished he asked me, "Why do you want to kill yourself?" I protested. I told him that the rewards I wanted were of sight, of pleasure, of the thrill of pitting my body and my skills against nature. My friend replied, "When you are as old as I am you will see that you are trying to kill yourself.""

"Some years later I spoke to a mentally disturbed young man. Very agitatedly, he described to me how alien beings from outer space had invaded the earth. They were formed of mental substance, lived in human minds, and controlled human beings through the creations of science and technology. Eventually this alien being would have an autonomous existence in the form of giant computers and would no longer require humans–and that would mark its triumph and the end of humanity. Soon he was hospitalized because he was unable to shake off this terrible vision."

"Science is a field which grows continuously with ever expanding frontiers. Further, it is truly international in scope. Any particular advance has been preceded by the contributions of those from many lands who have set firm foundations for further developments. The Nobel awards should be regarded as giving recognition to this general scientific progress as well as to the individuals involved. Further, science is a collaborative effort. The combined results of several people working together is often much more effective than could be that of an individual scientist working alone."

"... I can't work well under the conditions at Bell Labs. Walter and I are looking at a few questions relating to point-contact transistors, but Shockley keeps all the interesting problems for himself."

"On the morning of 1 November 1956 the US physicist John Bardeen dropped the frying-pan of eggs that he was cooking for breakfast, scattering its contents on the kitchen floor. He had just heard that he had won the Nobel Prize for Physics along with William Shockley and Walter Brattain for their invention of the transistor. That evening Bardeen was startled again, this time by a parade of his colleagues from the University of Illinois marching to the door of his home bearing champagne and singing "For He's a Jolly Good Fellow"."

"John Bardeen was an avid golfer and a good one. Whenever possible, he sought out golf courses during research or consulting trips. According to the stories, he was as proud of hitting a "hole in one" as he was to win a second Nobel Prize."

"You can’t imagine how wonderful it is to teach physics at MIT. The physics majors at MIT are there because they want to be there. Their love of physics is infectious...I've likened it to teaching art history in Rome."

"The theory community, myself included - became rather troubled about the particle."

"I feel I may be controversial in this, but I think that wisdom doesn't count for a lot in theoretical physics. It’s not like history and literature, where you accumulate a broader and broader world view. It’s not a question of energy; I have plenty of energy. I just wrote—just finished writing this massive book...I think most theoretical physicists do their best work when they're young, because they see problems fresh for the first time."

"If I were forced to sum up in one sentence what the Copenhagen interpretation says to me, it would be 'Shut up and calculate!'"

"One of the most beautiful papers in physics that I know of is yours in the American Journal of Physics."

"It once made sense to exclude the scientist from scientific explanations of the physical world. This warded off superstitious, animistic, or religious explanations. But without endorsing superstition, animism, or religion, today it makes sense to insist that the scientist should not be excluded from a philosophical understanding of the nature of scientific explanation. Why shouldn't such an understanding involve the explainer, as well as the explained?"

"It is a fundamental quantum doctrine that a measurement does not, in general, reveal a pre-existing value of the measured property. On the contrary, the outcome of a measurement is brought into being by the act of measurement itself, a joint manifestation of the state of the probed system and the probing apparatus. Precisely how the particular result of an individual measurement is brought into being—Heisenberg's "transition from the possible to the actual"—is inherently unknowable. Only the statistical distribution of many such encounters is a proper matter for scientific inquiry."

"Quantum mechanics is the most useful and powerful theory physicists have ever devised. Yet today, nearly 90 years after its formulation, disagreement about the meaning of the theory is stronger than ever. New interpretations appear every year. None ever disappear. … The message from QBism is this: You needn't feel guilty about never getting nervous about this stuff. You were right not to be bothered. But for the sake of intellectual coherence, you had better reexamine what you wrongly may have thought you understood perfectly well about the nature of probability."

"I would like to describe an attitude toward quantum mechanics which, whether or not it clarifies the interpretational problems that continue to plague the subject, at least sets them in a rather different perspective. This point of view alters somewhat the language used to address these issues—a glossary is provided in Appendix C—and it may offer a less perplexing basis for teaching quantum mechanics or explaining it to nonspecialists. It is based on one fundamental insight, perhaps best introduced by an analogy. My complete answer to the late 19th century question "what is electrodynamics trying to tell us" would simply be this:Fields in empty space have physical reality; the medium that supports them does not.Having thus removed the mystery from electrodynamics, let me immediately do the same for quantum mechanics:Correlations have physical reality; that which they correlate does not."

"An extrapolation of its present rate of growth reveals that in the not too distant future Physical Review will fill bookshelves at a speed exceeding that of light. This is not forbidden by general relativity since no information is being conveyed."

"… coincident with the explosive growth of research, the art of writing science suffered a grave setback, and the stultifying convention descended that the best scientific prose should sound like a non-human author addressing a mechanical reader. … We injure ourselves when we fail to make our discipline as clear and vibrant as we can to students - prospective scientists - and to the public who pay the taxes."

"Over the past fifty years or so, scientists have allowed the conventions of expression available to them to become entirely too confining."

"Have the climate models been successful in predicting anything? They, of course, predict substantial global warming. This is not surprising given the expressed belief of some of the model builders in the global warming hypothesis and the many parameters in the model that need to be introduced. However, the models also predict unambiguously that the atmosphere is warming faster than the surface of the earth; but all the available observational data unambiguously shows the opposite! Truth in science is always determined from observational facts. One finds the truth by making a hypothesis and comparing observations with the hypothesis. It is absolutely essential that one should be neutral and not fall in love with the hypothesis. If the facts are contrary to any predictions, then the hypothesis is wrong no matter how appealing. "Truth by Assertion" is not science."

"That Big Science culture in the USA, and similar groups elswhere, tended to have separate, direct access to government and hence to funding sources. It was independent to a great extent of the rest of science, of which it was never a majority component except in funding."

"“We atheists can . . . argue that, with the modern revolution in attitudes toward homosexuals, we have become the only group that may not reveal itself in normal social discourse”."

"My Harvard classmate, Thomas S. Kuhn wrote, some years ago, an influential book about scientific revolutions. Fortunately, many scientific revolutions do not follow his scenario, but the one he focused on, the discovery of quantum mechanics, is well described by his model, which is most valid for a revolution occurring in the central core of a mature science."

"All I can say to the younger theorists is: don’t trust anyone over 45, except maybe me, and I’m not so sure about me.”"

"“Of course I am not religious—I don’t in fact see how any scientist who thinks at all deeply can be so ...”"

"Surely there are more levels of organization between human ethology and DNA than there are between DNA and quantum electrodynamics, and each level can require a whole new conceptual structure."

"... the state of a really big system does not at all have to have the symmetry of the laws which govern it; in fact, it usually has less symmetry."
