Quotes About Physics

The first thing to realize about physics ... is its extraordinary indirectness.... For physics is not about the real world, it is about "abstractions" from the real world, and this is what makes it so scientific.... Theoretical physics runs merrily along with these unreal abstractions, but its conclusions are checked, at every possible point, by experiments.

There is no science in this world like physics. Nothing comes close to the precision with which physics enables you to understand the world around you. It's the laws of physics that allow us to say exactly what time the sun is going to rise. What time the eclipse is going to begin. What time the eclipse is going to end.

The usual derivation of the word Metaphysics is not to be sustainedthe science is supposed to take its name from its superiority to physics. The truth is, that Aristotle's treatise on Morals is next in succession to his Book of Physics.

I have tried to read philosophers of all ages and have found many illuminating ideas but no steady progress toward deeper knowledge and understanding. Science, however, gives me the feeling of steady progress: I am convinced that theoretical physics is actual philosophy. It has revolutionized fundamental concepts, e.g., about space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics), and it has taught us new methods of thinking (complementarity) which are applicable far beyond physics.

In case you haven't noticed, they're moving a lot faster. I don't know about the laws of physics on your planet, but where I come from an object moving at subclass speed can't catch up to one running at starclass. But if you know something about turbines, thrusters and engines, quantum or classical physics that I've somehow missed, then please enlighten me. - Caillen Dagan to Desideria Denarii

There are a few societies that show signs of having been very rational about the physics of construction and the physics of real life. Some of the old middle-Eastern societies had downdraft systems over whole cities, and passive, rapid-evaporation ice-making systems. They were rational people using good physical principles to make themselves comfortable without additional sources of energy.

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.

What would it mean if there were a theory that explained everything? And just what does "everything" actually mean, anyway? Would this new theory in physics explain, say the meaning of human poetry? Or how economics work? Or the stages of psychosexual development? Can this new physics explain the currents of ecosystems, or the dynamics of history, or why human wars are so terribly common?

Mathematical physics is in the first place physics and it could not exist without experimental investigations.

I do not think the division of the subject into two parts - into applied mathematics and experimental physics a good one, for natural philosophy without experiment is merely mathematical exercise, while experiment without mathematics will neither sufficiently discipline the mind or sufficiently extend our knowledge in a subject like physics.

Even if we ignore the 'non-theoretical' knowledge which we acquire through experience (such as the knowledge of what something tastes like) and concentrate on theoretical knowledge, there is no good reason to think that physics can literally give the theory of everything. Here I want to be really pedantic. Although everything may be subject to physical law, not everything can be explained or described in physical terms. Physics has literally nothing to say about society, morality and the mind, for example - but of course these are parts of 'everything'.

Instead of physicists teaching physics, physicists should go home and see what physics applies to their home.

Goddard represented a unique combination of visionary dedication and technological brilliance. He studied physics because he needed physics to get to Mars. In reading the notebooks of Robert Goddard, I am struck by how powerful his exploratory and scientific motivations were - and how influental speculative ideas, even erroneous ones, can be on the shaping of the future.

...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.

You want to fall, that's all. You think it can't go on like that. It's as if your life is a perch on the edge of a cliff and going forward seems impossible, not for a lack of will, but a lack of space. The possibility of another day stands in defiance of the laws of physics. And you can't go back. So you want to fall, let go, give up, but you can't. And every breath you take reminds you of that fact. So it goes.

We have to create miracles. A miracle is not the intersession of an external divine agency in violation of the laws of physics. A miracle is simply something that is impossible from an old story but possible from within a new one. It is an expansion of what is possible.

The response to my op-ed by global warming alarmists has been interesting. Former Vice President Al Gore has called me a "denier" and informs us that climate change is "a principle in physics. It's like gravity. It exists." Perhaps he's right. Climate change is like gravity - a naturally occurring phenomenon that existed long before, and will exist long after, any governmental attempts to affect it.

It's amazing to me that not only can we put a probe around Saturn and get images of its moons, but our math and physics are so freaking accurate we can say, "Hey, you know what? On this date at this time if we turn Cassini that way we'll see a moon over 2 million kilometers away pass in front of another one nearly 3 million kilometers away." Every morning, I have a 50/50 chance of finding my keys. That kinda puts things in perspective.

Politics is more difficult than physics.

Ancient wisdom and quantum physicists make unlikely bedfellows: In quantum mechanics the observer determines (or even brings into being) what is observed, and so, too, for the Tiwis, who dissolve the distinction between themselves and the cosmos. In quantum physics, subatomic particles influence each other from a distance, and this tallies with the aboriginal view, in which people, animals, rocks, and trees all weave together in the same interwoven fabric.

We the undersigned, intend to establish an instruction and training institution which differs from the common elementary schools principally in that it will embrace, outside of (in addition to) the general and elementary curriculum, all branches of the classical high school, which are necessary for a true Christian and scientific education, such as: Religion, the Latin, Greek, Hebrew, German, French and English languages; History, Geography, Mathematics, Physics, natural history, Introduction to Philosophy, Music, and Drawing.

Most people have no concept of how an automatic transmission works, yet they know how to drive a car. You don't have to study physics to understand the laws of motion to drive a car. You don't have to understand any of this stuff to use Macintosh.

I do not keep up with the details of particle physics.

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.

We live, I think, in the century of science and, perhaps, even in the century of 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.

The feeling persists that no one can simultaneously be a respectable writer and understand how a refrigerator works, just as no gentleman wears a brown suit in the city. Colleges may be to blame. English majors are encouraged, I know, to hate chemistry and physics, and to be proud because they are not dull and creepy and humorless and war-oriented like the engineers across the quad. And our most impressive critics have commonly been such English majors, and they are squeamish about technology to this very day. So it is natural for them to despise science fiction.

(On the energy radiated by the Sun) It's four hundred million million million million watts. That is a million times the power consumption of the United States every year, radiated in one second, and we worked that out by using some water, a thermometer, a tin, and an umbrella. And that's why I love physics.

The comic edge of Ghostbusters will always be the same. It's still treating the supernatural with a totally mundane sensibility. In the world of ghostbusting, there are certain givens. You're always going to have some new invented technology, some pseudo-science that sounds right because we drop enough familiar terms from physics and engineering, and pseudo-methodology, something that people will think they may have read something about before.

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.

I can't think that it would be terrible of me to say - and it is occasionally true - that I need physics more than friends.

The flaw is the business plan - digging up and burning way more carbon than physics says we can deal with. So, I suppose it's some kind of mid-point between writing them nice letters asking them to stop and figuring out a way to take down the entire system- which I don't have any idea how to do.

Thanks to those pesky laws of physics, when things aren't sustainable, they stop.

The game I play is a very interesting one. It's imagination in a straightjacket, which is this: that it has to agree with the known laws of physics. ... It requires imagination to think of what's possible, and then it requires an analysis back, checking to see whether it fits, whether its allowed, according to what's known, okay?

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.

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.

Politics is far more complicated than physics.

Quantum physics tells us that nothing that is observed is unaffected by the observer. That statement, from science, holds an enormous and powerful insight. It means that everyone sees a different truth because everyone is creating what they see.

Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature with the most generality and the greatest simplicity are very elegant and subtle.

The story of the universe finally comes to an end. For the first time in its life, the universe will be permanent and unchanging. Entropy finally stops increasing because the cosmos cannot get any more disordered. Nothing happens, and it keeps not happening, forever. It's what's known as the heat-death of the universe. An era when the cosmos will remain vast and cold and desolate for the rest of time the arrow of time has simply ceased to exist. It's an inescapable fact of the universe written into the fundamental laws of physics, the entire cosmos will die.

Eight months later, having left Columbia, I was studying physics in a summer program and working in Colorado when I decided to enroll as a graduate student in biophysics.

My travels through physics really are the same urges that make me travel through ecology. They are not really different, except that there is an added dimension of seeing ecological destruction and seeing the very life-support system that makes us survive on this planet being destroyed. That makes me do more than just inquire; it compels me to act and to intervene.

The physicist is like someone who's watching people playing chess and, after watching a few games, he may have worked out what the moves in the game are. But understanding the rules is just a trivial preliminary on the long route from being a novice to being a grand master. So even if we understand all the laws of physics, then exploring their consequences in the everyday world where complex structures can exist is a far more daunting task, and that's an inexhaustible one I'm sure.

I am not a climatologist, but I don't think any of the other witnesses are either. I do work in the related field of atomic, molecular and optical physics. I have spent my professional life studying the interactions of visible and infrared radiation with gases - one of the main physical phenomena behind the greenhouse effect. I have published over 200 papers in peer reviewed scientific journals.

I am now convinced that theoretical physics is actually philosophy.

Psychology, as the behaviorist views it, is a purely objective, experimental branch of natural science which needs introspection as little as do the sciences of chemistry and physics.... The position is taken here that the behavior of man and the behavior of animals must be considered in the same plane.

If I wasn't acting or doing stand-up, I would be in animation. Or if I had the discipline I might studies physics.
