The solution of the difficulty is that the two mental pictures which experiment lead us to form - the one of the particles, the other of the waves - are both incomplete and have only the validity of analogies which are accurate only in limiting cases.
The Book of Telling tells of a woman's journey to uncover the secret life of her father and to find herself in the process, an unusual counterpoint between personal history and the history of a young nation. Haunting, powerful, and beautifully written.
The system [of thought] doesn't stay with the difficult problem that produces unpleasant feelings. It's conditioned somehow to move as fast as it can toward more pleasant feelings, without actually facing the thing that's making the unpleasant feeling.
What is the source of all this trouble? I'm saying that the source is basically in thought. Many people would think that such a statement is crazy, because thought is the one thing we have with which to solve our problems. That's part of our tradition.
As for the forces, electromagnetism and gravity we experience in everyday life. But the weak and strong forces are beyond our ordinary experience. So in physics, lots of the basic building blocks take 20th- or perhaps 21st-century equipment to explore.
Should a young scientist working with me come to me after two years of such work and ask me what to do next, I would advise him to get out of science. After two years of work, if a man does not know what to do next, he will never make a real scientist.
If experiments are performed thousands of times at all seasons and in every place without once producing the effects mentioned by your philosophers, poets, and historians, this will mean nothing and we must believe their words rather than our own eyes?
His [Erwin Schrödinger's] private life seemed strange to bourgeois people like ourselves. But all this does not matter. He was a most lovable person, independent, amusing, temperamental, kind and generous, and he had a most perfect and efficient brain.
Some people seek meaning in life through personal gain, through personal relationship, or through personal experiences. However, it seems to me that being blessed with the intellect to divine the ultimate secrets of nature gives meaning enough to life.
By 2100, our destiny is to become like the gods we once worshipped and feared. But our tools will not be magic wands and potions but the science of computers, nanotechnology, artificial intelligence, biotechnology, and most of all, the quantum theory.
A poet once said, "The whole universe is in a glass of wine." We will probably never know in what sense he meant that, for poets do not write to be understood. But it is true that if we look at a glass of wine closely enough we see the entire universe.
In fact, current cosmological observations indicate that the average density of matter and energy in the universe is equal, within measurement errors, to the critical density for which the total energy of the universe was exactly zero at the beginning.
On another level, I want to mention that I have a strong Jewish identity and - over the years - have been involved in several Jewish projects, such as the establishment of a strong program of Judaic Studies at the University of California in San Diego.
Can quantum mechanics represent the fact that an electron finds itself approximately in a given place and that it moves approximately with a given velocity, and can we make these approximations so close that they do not cause experimental difficulties?
The law of right-left symmetry was used in classical physics but was not of any great practical importance there. One reason for this derives from the fact that right-left symmetry is a discrete symmetry, unlike rotational symmetry, which is continuous.
My suggestion is that at each state the proper order of operation of the mind requires an overall grasp of what is generally known, not only in formal logical, mathematical terms, but also intuitively, in images, feelings, poetic usage of language, etc.
The Prophecies of Daniel are all of them related to one another, as if they were but several parts of one general Prophecy, given at several times. The first is the easiest to be understood, and every following Prophecy adds something new to the former.
By his own admission, Carson's remarkable hand-eye coordination allowed him to soar as a surgeon, and he used that success to build a lucrative reputation as a purveyor of advice for young and old. His book for young people is titled 'You Have a Brain.'
What I do is very theoretical. It won't necessarily have implications for anything anyone is doing tomorrow, yet you know that there's a sense of progress in science, and as we understand more, it just turns out that, somehow, the world evolves with us.
I should like to suggest to you that the cause of all the economic troubles is that we have an economic system which tries to maintain an equality of value between two things, which it would be better to recognise from the beginning as of unequal value.
To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature ... If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in.
Many people do not like the idea that time has a beginning, probably because it smacks of divine intervention. (The Catholic Church, on the other hand, seized on the big bang model and in 1951 officially pronounced it to be in accordance with the Bible.
Not to leave planet Earth would be like castaways on a desert island not trying to escape...Sending humans to other planets ... will shape the future of the human race in ways we don't yet understand, and may determine whether we have any future at all.
My writings are an exploration, and I think a lot of writers would tell you this, but in writing, you're not simply putting down things that are already known to you. You're actually discovering in the writing process, you're actually creating knowledge.
I enjoy acting now more than I ever have. I've had lots of difficult times when I was younger, but that was all tied up with thwarted ambition. It's hard being a young actor, because you don't realise until later that it's only ever about doing the work.
I did a film in which Andy Garcia and Michael Keaton both played the leads, 'Desperate Measures,' and interestingly enough it was their biggest payday. The film didn't do well, and it kind of marked their careers. They've done less since. It all changed.
Every good laboratory consists of first rate men working in great harmony to insure the progress of science; but down at the end of the hall is an unsociable, wrong-headed fellow working on unprofitable lines, and in his hands lies the hope of discovery.
The trouble is that you won't get the scientists to agree on a course of action. It is almost instinctive in science to accept contrary views, because disagreeing gives you guidance to experimental tests of ideas - your own and those offered by others...
If you ask people why they move to the city, they always give the same reasons. They've come to get a job or follow their friends or to be at the center of a scene. That's why we pay the high rent. Cities are all about the people, not the infrastructure.
I call on all scientists in all countries to cease and desist from work creating, developing, improving and manufacturing further nuclear weapons - and, for that matter, other weapons of potential mass destruction such as chemical and biological weapons.
End of the sixties, Keith Blazey interested me to work on GdAlO3, an antiferromagnet on which he had done optic experiments. This started a fruitful cooperation on magnetic phase diagrams, which eventually brought me into the field of critical phenomena.
The degree and duration of the torment of these degenerate and anti-Christian people, should be no other than would be approved of by those angels who had ever labored for their salvation, and that Lamb who had redeemed them with his most precious blood.
Do not Bodies and Light act mutually upon one another; that is to say, Bodies upon Light in emitting, reflecting, refracting and inflecting it, and Light upon Bodies for heating them, and putting their parts into a vibrating motion wherein heat consists?
The mind of man has perplexed itself with many hard questions. Is space infinite, and in what sense? Is the material world infinite in extent, and are all places within that extent equally full of matter? Do atoms exist or is matter infinitely divisible?
Every existence above a certain rank has its singular points; the higher the rank the more of them. At these points, influences whose physical magnitude is too small to be taken account of by a finite being may produce results of the greatest importance.
The human mind evolved always in the company of the human body, and of the animal body before it was human. The intricate connections of mind and body must exceed our imagination, as from our point of view we are peculiarly prevented from observing them.
Of course, nobody would deny the importance of human beings for theological thinking, but the time span of history that theologians think about is a few thousand years of human culture rather than the fifteen billion years of the history of the universe.
The jury is not in, so we just don't know. But there are very strong indications that wormholes that a human could travel through are forbidden by the laws of physics. That's sad, that's unfortunate, but that's the direction in which things are pointing.
Some people are a little bit afraid about the future because they see all these gadgets and gizmos coming down the pike and they think they're too old to learn all this new stuff. But eventually they begin to realize, 'Hey, some of this stuff is useful.'
Our grandkids will lead the lives of the gods of mythology. Zeus could think and move objects around. We'll have that power. Venus had a perfect, timeless body. We'll have that, too. Pegasus was a flying horse. We'll be able to modify life in the future.
I got a four year scholarship to Harvard, and while I was there they wanted to groom me for work in the Star Wars program designing weapons ignited by hydrogen bombs. I didn't want to do that. I thought about how many scientists had died in World War II.
A physicist visits a colleague and notices a horseshoe hanging on the wall above the entrance. 'Do you really believe that a horseshoe brings luck?' he asks. 'No,' replies the colleague, 'but I've been told that it works even if you don't believe in it.'
All the evidence, experimental and even a little theoretical, seems to indicate that it is the energy content which is involved in gravitation, and therefore, since matter and antimatter both represent positive energies, gravitation makes no distinction.
Nobody, I believe, will deny, that we are to form our judgment of the true nature of the human mind, not from sloth and stupidity of the most degenerate and vilest of men, but from the sentiments and fervent desires of the best and wisest of the species.
So long as the universe had a beginning, we could suppose it had a creator. But if the universe is really completely self-contained, having no boundary or edge, it would have neither beginning nor end: it would simply be. What place, then, for a creator?
But what is the past? Could it be, the firmness of the past is just illusion? Could the past be a kaleidoscope, a pattern of images that shift with each disturbance of a sudden breeze, a laugh, a thought? And if the shift is everywhere, how would we know?
Science for me is very close to art. Scientific discovery is an irrational act. It's an intuition which turns out to be reality at the end of it-and I see no difference between a scientist developing a marvellous discovery and an artist making a painting.
From a scientific point of view, our mission is to seek answers to the fundamental questions about the universe. Many are open - we don't know about dark matter, which accounts for a quarter of the universe's matter, nor do we know why there's antimatter.
...nature seems very conversant with the rules of pure mathematics, as our own mathematicians have formulated them in their studies, out of their own inner consciousness and without drawing to any appreciable extent on their experience of the outer world.
Whatever I've worked on, I've always tried to make my writing personal. I think that's what makes my books somewhat different from what other scientists are doing. You have to tie concepts into everyday life, or they just won't be interesting for readers.
