Quotes About Physics

It seems that every practitioner of physics has had to wonder at some point why mathematics and physics have come to be so closely entwined. Opinions vary on the answer. ..Bertrand Russell acknowledged..'Physics is mathematical not because we know so much about the physical world, but because we know so little.' ..Mathematics may be indispensable to physics, but it obviously does not constitute physics.

The world of conceptualized ideas is quite wonderful, even when it's - like Aristotle's Physics - an outmoded book. The physics is not true. But the reasoning is dazzling.

It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we say about nature.

In physics, your solution should convince a reasonable person. In math, you have to convince a person who's trying to make trouble. Ultimately, in physics, you're hoping to convince Nature. And I've found Nature to be pretty reasonable.

When asked ... [about] an underlying quantum world, Bohr would answer, 'There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about Nature.'

I still can't figure out what inspired me to do physics. But since I was nine or ten years old, I wanted to be like [Albert] Einstein. He was my hero. I knew no physicists. I knew no scientists. I had nobody around me. And I went to a convent that didn't even have higher mathematics and physics. I taught myself these subjects in order to get into university.

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.

Physics is the science of all the tremendously powerful invisibilities - of magnetism, electricity, gravity, light, sound, cosmic rays. Physics is the science of the mysteries of the universe. How could anyone think it dull?

What appear to be the most valuable aspects of the theoretical physics we have are the mathematical descriptions which enable us to predict events. These equations are, we would argue, the only realities we can be certain of in physics; any other ways we have of thinking about the situation are visual aids or mnemonics which make it easier for beings with our sort of macroscopic experience to use and remember the equations.

People have been talking about multiverses as a philosophical idea for a long time. But the current incarnations in physics, I think, are more indicative of problems with some things going on at the frontier of physics than ideas that are gonna last.

What really matters for me is ... the more active role of the observer in quantum physics ... According to quantum physics the observer has indeed a new relation to the physical events around him in comparison with the classical observer, who is merely a spectator.

The information contained in an English sentence or computer software does not derive from the chemistry of the ink or the physics of magnetism, but from a source extrinsic to physics and chemistry altogether. Indeed, in both cases, the message transcends the properties of the medium. The information in DNA also transcends the properties of its material medium.

The laws of history are as absolute as the laws of physics, and if the probabilities of error are greater, it is only because history does not deal with as many humans as physics does atoms, so that individual variations count for more.

Now these two questions Does there exist a material reality distinct from sensible appearances? and What is the nature of reality? do not have their source in experimental method, which is acquainted only with sensible appearances and can discover nothing beyond them. The resolution of these questions transcends the methods used by physics; it is the object of metaphysics. Therefore, if the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics.

Given that I was interested in physics, I think it was easier for me to do physics in India.

The pace of science forces the pace of technique. Theoretical physics forces atomic energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced -- by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.

Physics as we know it will be over in six months.

...the laws of physics, carefully constructed after thousands of years of experimentation, are nothing but the laws of harmony one can write down for strings and membranes. The laws of chemistry are the melodies that one can play on these strings. the universe is a symphony of strings. And the "Mind of God," which Einstein wrote eloquently about, is cosmic music resonating throughout hyperspace.

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... How vivid is the claret, pressing its existence into the consciousness that watches it! If our small minds, for some convenience, divide this glass of wine, this universe, into parts - physics, biology, geology, astronomy, psychology, and so on - remember that nature does not know it! So let us put it all back together, not forgetting ultimately what it is for. Let it give us one more final pleasure: drink it and forget it all!

Bohm's interpretation of quantum physics indicated that at the subquantum level, the level in which the quantum potential operated, location ceased to exist. All points in space became equal to all other points in space, and it was meaningless to speak of anything as being separate from anything else. Physicists call this property 'nonlocality.'

Sometimes the public says, 'What's in it for Numero Uno? Am I going to get better television reception? Am I going to get better Internet reception?' Well, in some sense, yeah. ... All the wonders of quantum physics were learned basically from looking at atom-smasher technology. ... But let me let you in on a secret: We physicists are not driven to do this because of better color television. ... That's a spin-off. We do this because we want to understand our role and our place in the universe.

Mathematics should be mixed not only with physics but with ethics.

Why do cats sleep so much? Perhaps they've been trusted with some major cosmic task, an essential law of physics - such as: if there are less than five million cats sleeping at any one time the world will stop spinning.

Physiology is the science which treats of the properties of organic bodies, animal and vegetable, of the phenomena they present, and of the laws which govern their actions. Inorganic substances are the objects of other sciences, - physics and chemistry.

All of physics is either impossible or trivial. It is impossible until you understand it, and then it becomes trivial.

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

It is odd, but on the infrequent occasions when I have been called upon in a formal place to play the bongo drums, the introducer never seems to find it necessary to mention that I also do theoretical physics.

I quite like the transitions of being an actor, because you get to explore these little pockets of life. So if you're playing a builder you get to know about building, if you're playing a scientist or a physician or something you get to know about physics. And similarly with this world I like exploring their culture, that very sort of upper middle class, addictive... that's part of the reason I love it.

When we form heart-centered beliefs within our bodies, in the language of physics we're creating the electrical and magnetic expression of them as waves of energy, which aren't confined to our hearts or limited by the physical barrier of our skin and bones. So clearly we're speaking to the world around us in each moment of every day through a language that has no words: the belief-waves of our hearts.

Biology is now bigger than physics, as measured by the size of budgets, by the size of the workforce, or by the output of major discoveries; and biology is likely to remain the biggest part of science through the twenty-first century.

Considered as a mere question of physics, (and keeping all moral considerations entirely out of sight,) the appearance of man is a geological phenomenon of vast importance, indirectly modifying the whole surface of the earth, breaking in upon any supposition of zoological continuity, and utterly unaccounted for by what we have any right to call the laws of nature.

One can't prove that God doesn't exist. But science makes God unnecessary. The laws of physics can explain the universe without the need for a creator.

Natural science physics contains in itself synthetical judgments a priori, as principles. ... Space then is a necessary representation a priori, which serves for the foundation of all external intuitions.

If a handful of people look at the making of the film and realize, "Oh, my god!" It was so complicated. It was like doing quantum physics calculations every day while you're telling a joke. It was so insane! So, they can feel my pain.

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

In the 20th century philosophy of time for a great many theorists became part of science because it was time as is studied in physics that became the object of philosophical speculation. That's very different from the way time has normally been understood.

My father was on the faculty in the Chemistry Department of Harvard University; my mother had one year of graduate work in physics before her marriage.

Physics admits of a lovely unification, not just at the level of fundamental forces, but when considering its extent and implications. Classifications like "optics" or "thermodynamics" are just straitjackets, preventing physicists from seeing countless intersections.

As physics is a mental reconstruction of material processes, perhaps a physical reconstruction of psychic processes is possible in nature itself.

The bottom line is that time travel is allowed by the laws of physics.

The more science I studied, the more I saw that physics becomes metaphysics and numbers become imaginary numbers. The farther you go into science, the mushier the ground gets. You start to say, 'Oh, there is an order and a spiritual aspect to science.

There are good reasons why we don't want everyone to learn nuclear physics, medicine or how financial markets work. Our entire modern project has been about delegating power over us to skilled people who want to do the work and be rewarded accordingly.

If you were running a solar company you may be okay - you may be able to keep growing. The question for physics is: Can you grow fast enough to begin to catch up with the damage?

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

Philosophers have not kept up with modern developments in science. Particularly physics.

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.

That which is not measurable is not science. That which is not physics is stamp collecting.

Statistics is, or should be, about scientific investigation and how to do it better, but many statisticians believe it is a branch of mathematics. Now I agree that the physicist, the chemist, the engineer, and the statistician can never know too much mathematics, but their objectives should be better physics, better chemistry, better engineering, and in the case of statistics, better scientific investigation. Whether in any given study this implies more or less mathematics is incidental.
