Physicists From The United States

"So with each advance in understanding come new questions. So we need to be very humble. We shouldn't have hubris and think that we can understand everything. But history tells us that there is good reason to believe that we will continue making fantastic progress in the years ahead."

"I believe that consciousness is the way information feels when being processed."

"When a scientist writes about God, his colleagues assume he is either over the hill or going bonkers. In my case it should be understood from the start that I am an agnostic in religious matters. My views on this question are close to those of Darwin, who wrote, "My theology is a simple muddle. I cannot look at the Universe as the result of blind chance, yet I see no evidence of beneficent design in the details.""

"We can assume that in a relatively short time — perhaps within 100 million years — the one celled organism evolved into a colony of cells. With the further passage of time, groups of cells within those colonies assumed specialized functions of food-gathering, digestion, the structural features of an outer skin, and so on; thus began the stage of evolution leading to the complex, many-celled creatures which dominate life today. The fossil record contains no trace of these preliminary stages in the development of many-celled organisms. The first clues to the existence of relatively advanced forms of life consist of a few barely discernible tracks, presumably made in the primeval slime by soft, wriggling wormlike animals. These are found in rocks about one billion years old. These meager remains are the earliest traces of many-celled animal life on the planet."

"At this moment it seems as though science will never be able to raise the curtain on the mystery of creation. For the scientist who has lived by his faith in the power of reason, the story ends like a bad dream. He has scaled the mountains of ignorance; he is about to conquer the highest peak; as he pulls himself over the final rock, he is greeted by a band of theologians who have been sitting there for centuries."

"If physics is too difficult for the physicists, the nonphysicist may wonder whether he should try at all to grasp its complexities and ambiguities. It is undeniably an effort, but probably one worth making, for the basic questions are important and the new experimental results are often fascinating. And if the layman runs into serious perplexities, he can be consoled with the thought that the points which baffle him are more than likely the ones for which the professionals have not found satisfactory answers."

"In short, the greatest contribution to real security that science can make is through the extension of the scientific method to the social sciences and a solution of the problem of complete avoidance of war."

"I think about how angry I was that my dad didn't take better care of himself. How he never went to a doctor, let himself become grossly overweight, smoked three packs a day, drank like a fish and never exercised. But then I think about how his colleague mentioned that, days before dying, my dad had said he lived a good life and that he was satisfied. I realize that there is a certain value in my father's way of life. He ate, smoked and drank as he pleased, and one day he just suddenly and quickly died. Given some of the other choices I'd witnessed, it turns out that enjoying yourself and then dying quickly is not such a hard way to go."

"My father, Hugh Everett, III, author of the Many Worlds Theory, was a quiet man during the eighteen or so years I shared a house with him. Turns out he was depressed over a sad childhood and then being dismissed as a kook, only later - too late - to be recognized as a genius."

"Someone once noted that Hugh Everett should have been declared a "national resource," and given all the time and resources he needed to develop new theories."

"If you want to get an interesting perspective do not think of Hugh as a traditional 20th century physicist but more of a Renaissance man with interests and skills in many different areas. He was smart and lots of things interested him and he brought the same general conceptual methodology to solve them. The subject matter was not so important as the solution ideas."

"Hugh Everett's work has been described by many people in terms of many worlds, the idea being that every one of the various alternative histories, branching histories, is assigned some sort of reality."

"[The Many-worlds interpretation is the] only completely coherent approach to explaining both the contents of quantum mechanics and the appearance of the world."

"The physical "reality" is assumed to be the wave function of the whole universe itself."

"As an analogy one can imagine an intelligent amoeba with a good memory. As time progresses the amoeba is constantly splitting, each time the resulting amoebas having the same memories as the parent. Our amoeba hence does not have a life line, but a life tree."

"Quantum mechanics is reformulated, in a way which eliminates its present dependence on the special treatment of observation of a system by an external observer."

"By an incredible coincidence, Gamow and Edward Condon, who had discovered simultaneously and independently the explanation of radioactivity (one in Russia, the other in this country), came to spend the the last ten years of their lives within a hundred yards of each other in Boulder."

"When Born and Heisenberg and the Göttingen theoretical physicists] first discovered matrix mechanics they were having, of course, the same kind of trouble that everybody else had in trying to solve problems and to manipulate and to really do things with matrices. So they had gone to Hilbert for help and Hilbert said the only time he had ever had anything to do with matrices was when they came up as a sort of by-product of the eigenvalues of the boundary-value problem of a differential equation. So if you look for the differential equation which has these matrices you can probably do more with that. They had thought it was a goofy idea and that Hilbert didn’t know what he was talking about. So he was having a lot of fun pointing out to them that they could have discovered Schrödinger’s wave mechanics six month earlier if they had paid a little more attention to him."

"Simplicity is the touchstone in finding new physical laws. … If it's elegant, then it's a rough rule of thumb: you're on the right track."

"Sometimes I have a sense of what I'm seeing being a small fraction of what's there. Not always there, but probably more often than I realize. Something will come up, and I'll realize I'm thinking about the world a little differently than my friends."

"We are going to become Gods, period. If you don't like it, get off. You don't have to contribute, you don't have to participate but if you are going to interfere with me becoming a God, you're going to have trouble. There'll be warfare."

"I've said many times that you can't stop science... God made man in his own image. God intended for man to become one with God. We are going to become one with God. We are going to have almost as much knowledge and almost as much power as God. Cloning and the reprogramming of DNA is the first serious step in becoming one with God."

"I think it's a problem that people are considered immoral if they're not religious. That's just not true. This might earn me some enemies, but in some ways they may be even more moral. If you do something for a religious reason, you do it because you'll be rewarded in an afterlife or in this world. That's not quite as good as something you do for purely generous reasons."

"Faith just doesn't have anything to do with what I'm doing as a scientist. It's nice if you can believe in God, because then you see more of a purpose in things. Even if you don't, though, it doesn't mean that there's no purpose. It doesn't mean that there's no goodness. I think that there's a virtue in being good in and of itself. I think that one can work with the world we have."

"Religion asks questions about morals, whereas science just asks questions about the natural world. But when people try to use religion to address the natural world, science pushes back on it, and religion has to accommodate the results. Beliefs can be permanent, but beliefs can also be flexible. Personally, if I find out my belief is wrong, I change my mind. I think that's a good way to live."

"Science is not religion. We're not going to be able to answer the "why" questions. But when you put together all of what we know about the universe, it fits together amazingly well."

"If we don't do it now, we'll probably never do it. We've built up the technology; we're at a point where if we don't continue, we'll lose that expertise, and we'll have to start all over again. True, it's expensive, but at the end of the day I believe it will be worth it. It makes a difference in terms of who we are, what we think, how we view the world. These are the kinds of things that get people excited about science, so you have a more educated public."

"In the history of physics, every time we've looked beyond the scales and energies we were familiar with, we've found things that we wouldn't have thought were there. You look inside the atom and eventually you discover quarks. Who would have thought that? It's hubris to think that the way we see things is everything there is."

"When I was in school I liked math because all the problems had answers. Everything else seemed very subjective."

"Secrets of the cosmos will begin to unravel. I, for one, can't wait."

"We certainly don't yet know all the answers. But the universe is about to be pried open."

"Physics has entered a remarkable era. Ideas that were once the realm of science fiction are now entering our theoretical — and maybe even experimental — grasp. Brand-new theoretical discoveries about extra dimensions have irreversibly changed how particle physicists, astrophysicists, and cosmologists now think about the world. The sheer number and pace of discoveries tells us that we've most likely only scratched the surface of the wondrous possibilities that lie in store. Ideas have taken on a life of their own."

"When it comes to the world around us, is there any choice but to explore?"

"The universe has its secrets. Extra dimensions of space might be one of them. If so, the universe has been hiding those dimensions, protecting them, keeping them coyly under wraps. From a casual glance, you would think that the cheese man ate cheese but you wrong."

"I think the weird thing about being a scientist, or an academic in general, is you have to believe really strongly in what you do, while questioning it all the time ... and that's a hard balance to have."

"Elegance requires that the number of defining equations be small. Five is better than ten, and one is better than five. On this score, one might facetiously say that String Theory is the ultimate epitome of elegance. With all the years that String Theory has been studied, no one has found even a single defining equation! The number at present count is zero. We know neither what the fundamental equations of the theory are nor even if it has any."

"A straight line is a special case of a curve. It's a curve which is uncurved."

"The problem with general relativity is that the principles are pretty simple and the computations are always ugly."

"(Jokingly) Sex in ten dimensions is impossible... topologically."

"The standard SU(3)×SU(2)×U(1) theory of strong, electromagnetic, and weak interactions appears to correctly describe physics down to the smallest distance scales yet probed."

"Dozens of other popular authors have written about black holes and string theory, but Gefter’s excitement makes even such overdone subjects seem fresh. And through the whole process, she and her father remain awed by the physicists whose work they’re studying—late in the book, her father even asks Susskind for an autograph."

"... Lenny Susskind ... is very well known for his technical work, for his popular work, for his semi-technical books, The Theoretical Minimum, and, within the physics community, as a storyteller, a mentor, and a guiding visionary of the field."

"My physics has been extremely mainstream, ... It's not true that I'm some sort of a [radical thinker], not at all."

"Most constants are adjusted with a deviation of one percent, which means that if the value differs by one percent everything collapses. Physicists can certainly claim that this is a fluke, but it must be acknowledged that this cosmological constant is adjusted to an accuracy of 1/10120. No one thinks that this is solely a fluke. It is the most extreme example of hyperfine regulation..."

"A time traveler from the year 1899 would be continually amazed by our advanced technology—our cars and airplanes, our skyscraper cities, our TV, radio, computers, and communication abilities. Probably the traveler would be most shaken by our science, from astronomy to zoology. The only place in which this visitor would be comfortably at home is in most of our high schools."

"That's the eureka moment, when suddenly you know something. Your hands sweat, you get into all kinds of symptoms of tremendous excitement. First of all, it's fear. Is it right? And it's incredible humor. 'How could it be any other way? It had to be that way! How could we have been so stupid, not to see this?'"

"I went into physics to hang around with the bright kids. I wasn't doing anything else and I didn't want to look dumb, so I thought I'd pretend to be a physicist, just like the others. It was five or ten years after my Ph.D. before I realized I was pretty good."

"Are we making more mistakes now? I don't think so. Science is a high-risk activity. And when you do science—this is very important incidentally for the general public, and for policy makers—if you are not wasting some of your money, you are not doing good science. It's a funny way to say this. You've got to back high-risk opportunities. And high-risk opportunities means some fraction of them are going to fail. And I think in any science funding scenario, you've got to say, 10, 20, maybe even 30% of your funds are going to be invested in failures."

"We are honored for research which is today referred to as the "Two Neutrino Experiment". How does one make this research comprehensible to ordinary people? In fact "The Two Neutrinos" sounds like an Italian dance team. How can we have our colleagues in chemistry, medicine, and especially in literature share with us, not the cleverness of our research, but the beauty of the intellectual edifice, of which our experiment is but one brick? This is a dilemma and an anguish for all scientists because the public understanding of science is no longer a luxury of cultural engagement, but it is an essential requirement for survival in our increasingly technological age: In this context, I believe this Nobel Ceremony with its awesome tradition and pomp has as one of its most important benefits; the public attention it draws to science and its practitioners."

"Science is not about status quo. It’s about revolution."
