Physics Quotes

Ultimately, my Ph.D. is in mathematical physics, focusing on quantum field theory and curved space-time, and I worked with Stephen Hawking.

The one thing we can't really train for is weightlessness, real weightlessness. It's a ton of fun. It's pure Newtonian physics. You push in one direction, you go in the opposite direction with an equal force.

I was not going to be an actor. I was an engineer in physics. That's what I did: I graduated with a physics degree, and I had become a little bit distressed that I'd have to work for somebody - anybody! And I thought, "I'm not going to make a mark on anything. If I can't express myself, then I don't know what the heck I'm going to do with this life." I think it was just one of those germs that said, "No, no, no, you've got to say things. You've got to tell people things. You've got to express your opinion in this life, because that's how you started."

What is it possible to do well, in physics particularly, if things are not reduced to degrees and measures?

To understand that, we have to begin to imagine what a universe would be like if there wasn't anything in it called Mind. If that was the case, according to quantum physics now, then every possibility would also come into existence as every other possibility.

I enjoyed mathematics from a very young age. At the beginning of college, I had this illusion, which was kind of silly in retrospect, that if I just understood math and physics and philosophy, I could figure out everything else from first principles.

Basically, I wasn't properly socialized, so it made sense to do physics.

Quantum physics thus reveals a basic oneness of the universe.

Nothing is done. Everything in the world remains to be done or done over. The greatest picture is not yet painted, the greatest play isn't written, the greatest poem is unsung. There isn't in all the world a perfect railroad, nor a good government, nor a sound law. Physics, mathematics, and especially the most advanced and exact of the sciences are being fundamentally revised. . . Psychology, economics, and sociology are awaiting a Darwin, whose work in turn is awaiting an Einstein.

As a scholarly discipline, economics has always suffered from physics envy.

One man may have some special knowledge at first-hand about the character of a river or a spring, who otherwise knows only what everyone else knows. Yet to give currency to this shred of information, he will undertake to write on the whole science of physics. From this fault many great troubles spring.

While there is such a thing as correctness in ethics, in interpretation, in mathematics, the way to understand that is not by trying to model it on the ways in which we get things right in physics.

Quantum physics presents a new and exciting worldview that challenges old concepts, such as deterministic trajectories of motion and causal continuity. If initial conditions do not forever determine an object's motion, if instead, every time we observe, there is a new beginning, then the world is creative at the base level.

All the quantum physics experiments have occurred chiefly on the atomic scale and we are taught to believe that nature's laws are consistent.

We shouldn't be surprised that conditions in the universe are suitable for life, but this is not evidence that the universe was designed to allow for life. We could call order by the name of God, but it would be an impersonal God. There's not much personal about the laws of physics.

There are many hypotheses in physics of almost comparable brillance and elegance that have been rejected because they did not survive such a confrontation with experiment. In my view, the human condition would be greatly improved if such confrontations and willingness to reject hypotheses were a regular part of our social, political, economic, religious and cultural lives.

We have a closed circle of consistency here: the laws of physics produce complex systems, and these complex systems lead to consciousness, which then produces mathematics, which can then encode in a succinct and inspiring way the very underlying laws of physics that gave rise to it.

The primary consequence of the computational nature of the universe is that the universe naturally generates complex systems, such as life. Although the basic laws of physics are comparatively simple in form, they give rise, because they are computationally universal, to systems of enormous complexity.

Physics is becoming so unbelievably complex that it is taking longer and longer to train a physicist. It is taking so long, in fact, to train a physicist to the place where he understands the nature of physical problems that he is already too old to solve them.

Experimental high energy physics research is a group effort. I have been very fortunate to have had outstanding students and colleagues who have made invaluable contributions to the research with which I have been associated.

Science is the attempt to make the chaotic diversity of our sense-experience correspond to a logically uniform system of thought.

Quantum physics has found that there is no empty space in the human cell, but it is a teeming, electric-magnet ic field of possibility or potential

Understanding how DNA transmits all it knows about cancer, physics, dreaming and love will keep man searching for some time.

There is no true understanding of Biology without Chemistry. And there's no true understanding of Chemistry without Physics.

The ultimate aim of the modern movement in biology is in fact to explain all biology in terms of physics and chemistry.

Physics investigates the essential nature of the world, and biology describes a local bump. Psychology, human psychology, describes a bump on the bump.

And the actual achievements of biology are explanations in terms of mechanisms founded on physics and chemistry, which is not the same thing as explanations in terms of physics and chemistry.

We were making the first step out of the age of chemistry and physics, and into the age of biology.

If it squirms, it's biology; if it stinks, it's chemistry; if it doesn't work, it's physics; and if you can't understand it, it's mathematics.

The basic science is not physics or mathematics but biology -- the study of life. We must learn to think both logically and bio-logically.

It is easy to make out three areas where scientists will be concentrating their efforts in the coming decades. One is in physics, where leading theorists are striving, with the help of experimentalists, to devise a single mathematical theory that embraces all the basic phenomena of matter and energy. The other two are in biology. Biologists-and the rest of us too-would like to know how the brain works and how a single cell, the fertilized egg cell, develops into an entire organism

A certain kind of methodologically-minded philosopher of science is quick to read off metaphysical conclusions from features of scientific practice. Chemists don't derive their laws from fundamental physics, so reductive physicalism must be false. Biologists refer to natural numbers in some of their explanations, so numbers must exist. I think that this kind of thing makes for bad philosophy.

In some ways I'm a frustrated scientist or mathematician. The amount of times I've thought I'd go back to university and do theoretical physics because I like the big questions, but really I know now that that's not quite me. What's me is to do it in novels.

Mathematics catalogues everything that is not self-contradictory; within that vast inventory, physics is an island of structures rich enough to contain their own beholders.

Economists suffer from a deep psychological disorder that I call 'physics envy'. We wish that 99 percent of economic behavior could be captured by three simple laws of nature. In fact, economists have 99 laws that capture 3 percent of behavior. Economics is a uniquely human endeavor.

But in due course it became evident that not only a physical situation qua physics, but the meaning of that situation to people, was sometimes a factor, through the behavior of people, in the start of a fire.

Physics filled me with awe, put me in touch with a sense of original causes. Physics brought me closer to God. That feeling stayed with me throughout my years in science. Whenever one of my students came to me with a scientific project, I asked only one question, 'Will it bring you nearer to God?'

From all we have learnt about the structure of living matter, we must be prepared to find it working in a manner that cannot be reduced to the ordinary laws of physics. And that not on the ground that there is any 'new force' or what not, directing the behaviour of the single atoms within a living organism, but because the construction is different from anything we have yet tested in the physical laboratory.

A physicist is an atom's way of knowing about atoms.

It is natural that a man should consider the work of his hands or his brain to be useful and important. Therefore nobody will object to an ardent experimentalist boasting of his measurements and rather looking down on the 'paper and ink' physics of his theoretical friend, who on his part is proud of his lofty ideas and despises the dirty fingers of the other. Experiment and Theory in Physics

The fundamental laws necessary for the mathematical treatment of a large part of physics and the whole of chemistry are thus completely known, and the difficulty lies only in the fact that application of these laws leads to equations that are too complex to be solved.

Twentieth-century developments in science support a new animism. Developments in physics have led to a world of energetic events which seem to be self-moving and to behave in unpredictable ways. And recent studies in biology seem to demonstrate that bacteria and macromolecules have elemental forms of perception, memory, choice, and self-motion.

Modern science cannot explain why the laws of physics are exactly balanced for animal life to exist.

A careful analysis of the process of observation in atomic physics has shown that the subatomic particles have no meaning as isolated entities, but can only be understood as interconnections between the preparation of an experiment and the subsequent measurement.

The fact that Science walks forward on two feet, namely theory and experiment, is nowhere better illustrated than in the two fields for slight contributions to which you have done me the great honour of awarding the the Nobel Prize in Physics for the year 1923. Sometimes it is one foot that is put forward first, sometimes the other, but continuous progress is only made by the use of both-by theorizing and then testing, or by finding new relations in the process of experimenting and then bringing the theoretical foot up and pushing it on beyond, and so on in unending alterations.

Not only in geometry, but to a still more astonishing degree in physics, has it become more and more evident that as soon as we have succeeded in unraveling fully the natural laws which govern reality, we find them to be expressible by mathematical relations of surprising simplicity and architectonic perfection. It seems to me to be one of the chief objects of mathematical instruction to develop the faculty of perceiving this simplicity and harmony.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.

In science it often happens that scientists say, "You know that's a really good argument; my position is mistaken..."

Hundreds of years ago, Indian artists created visual images of dancing Shivas in a beautiful series of bronzes. In our time, physicists have used the most advanced technology to portray the patterns of the cosmic dance. The metaphor of the cosmic dance thus unifies ancient mythology, religious art and modern physics.

The physics chip adds a level of reality in games we just haven't been able to get.
