Quotes About Physics

I began to realize something - to understand the future you have to understand physics. Physics of the last century gave us television, radio, microwaves, gave us the Internet, lasers, transistors, computers - all of that from physics.

Philosophy used to be a field that had content, but then natural philosophy became physics, and physics has only continued to make inroads. Every time theres a leap in physics, it encroaches on these areas that philosophers have carefully sequestered away to themselves, and so then you have this natural resentment on the part of philosophers.

This change in the conception of reality is the most profound and the most fruitful that physics has experienced since the time of Newton. Refering to James Clerk Maxwell's contributions to physics.

A sound Physics of the Earth should include all the primary considerations of the earth's atmosphere, of the characteristics and continual changes of the earth's external crust, and finally of the origin and development of living organisms. These considerations naturally divide the physics of the earth into three essential parts, the first being a theory of the atmosphere, or Meteorology, the second, a theory of the earth's external crust, or Hydrogeology, and the third, a theory of living organisms, or Biology.

It's becoming clear that in a sense the cosmos provides the only laboratory where sufficiently extreme conditions are ever achieved to test new ideas on particle physics. The energies in the Big Bang were far higher than we can ever achieve on Earth. So by looking at evidence for the Big Bang, and by studying things like neutron stars, we are in effect learning something about fundamental physics.

I regard physics as that subset of magic that works fairly reliably. I regard magick, in the traditional sense, as a kind of physics that we strive to understand and render more reliable. So it all comes down to the same thing, a quest to understand and manipulate the world with a self-consistent and coherent theory .

Eugene Wigner wrote a famous essay on the unreasonable effectiveness of mathematics in natural sciences. He meant physics, of course. There is only one thing which is more unreasonable than the unreasonable effectiveness of mathematics in physics, and this is the unreasonable ineffectiveness of mathematics in biology.

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?

I gained a first class degree in Physics at Imperial College London in 1968 and did research in solid state physics, but did not pursue meteorology matters until gaining an M.Sc. in astrophysics from Queen Mary College London in 1981, after which I investigated and attempted to construct theories of solar activity.

I was a terrible high school student outside of the fact that I did well in physics, but there's a big difference between being good at physics and being a physicist, so I jettisoned that very quickly.

A consistent pursuit of classical physics forces a transformation in the very heart of that physics.

One of the most beautiful papers in physics that I know of is yours in the American Journal of Physics.

Science seems to be at war with itself.... Naive realism leads to physics, and physics, if true, shows naive realism to be false. Therefore naive realism, if true, is false; therefore it is false.

This book is about physics and its about physics and its relationship with mathematics and how they seem to be intimately related and to what extent can you explore this relationship and trust it.

The fact that the laws of physics don't change as if you move in time has physical implications that there's this thing called energy and energy is conserved, and the same thing - and the fact that the laws of physics don't change of you move back and forth in different directions in space implies that there is something called momentum and momentum is conserve and doesn't change as you evolve in time.

Scientific realism in classical (i.e. pre-quantum) physics has remained compatible with the naive realism of everyday thinking on the whole; whereas it has proven impossible to find any consistent way to visualize the world underlying quantum theory in terms of our pictures in the everyday world. The general conclusion is that in quantum theory naive realism, although necessary at the level of observations, fails at the microscopic level.

If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them.

My personal background is actually very unusual for the kind of career I chose. I didn’t meet anyone who had ever done physics in my life. I grew up in the Himalayan forests. My father was a forest conservator, which meant that if I wasn’t in school I was in the forests with him. That has been very largely responsible for my ecological inclinations.

Our job in physics is to see things simply, to understand a great many complicated phenomena in a unified way, in terms of a few simple principles.

Science Fiction is not just about the future of space ships travelling to other planets, it is fiction based on science and I am using science as my basis for my fiction, but it's the science of prehistory - palaeontology and archaeology - rather than astronomy or physics.

Charting is a little like surfing. You dont have to know a lot about the physics of tides, resonance, and fluid dynamics in order to catch a good wave. You just have to be able to sense when its happening and then have the drive to act at the right time.

The fundamental concept in social science is Power, in the same sense in which Energy is the fundamental concept in physics.

The task of asking nonliving matter to speak and the responsibility for interpreting its reply is that of physics.

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.

Our civil rights have no dependence upon our religious opinions more than our opinions in physics or geometry.

Brian and I were both science students. You know science sort of math and physics side, you know.

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

I'm a fan of the simulation theory. I tend to think that most of our existence, if not all of it, is part of a hologram created by some type of other life form, or some type of other artificial intelligence. Now, it may be impossible for us to ever know that, but a bunch of recent studies in string theory physics have proved that.

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.

There may be organic life out there, or maybe machines created by long-dead civilizations, but any signals, even if they are difficult to decode, would tell us that the concepts of logic and physics are not limited to the hardware in human skulls, and will transform our view of the universe.

He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one. Mathematics should be mixed not only with physics but with ethics; that is mixed mathematics. The fact which interests us most is the life of the naturalist. The purest science is still biographical.

The universe is the externisation of the soul. Wherever the life is, that bursts into appearance around it. Our science is sensual, and therefore superficial. The earth, and the heavenly bodies, physics, and chemistry, we sensually treat, as if they were self-existent; but these are the retinue of that Being we have.

It is impossible to trap modern physics into predicting anything with perfect determinism because it deals with probabilities from the outset.

Nevertheless, if I have at times been able to make original contributions in the accelerator field, I cannot help feeling that to a certain extent my slightly amateur approach in physics, combined with much practical experience, was an asset.

I never went into physics or the astronaut corps to become a role model. But after my first flight, it became clear to me that I was one. And I began to understand the importance of that to people. Young girls need to see role models in whatever careers they may choose, just so they can picture themselves doing those jobs someday. You can't be what you can't see.

Without us here to witness, the universe is just pointless physics unfolding.

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.

Cambridge was the place for someone from the Colonies or the Dominions to go on to, and it was to the Cavendish Laboratory that one went to do physics.

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.

No inanimate object is ever fully determined by the laws of physics and chemistry.

Every force field is simultaneously a field of information because even physics now acknowledges that an atom is not only a hierarchy of different states of energy, or different states of force fields.

Politicians think that if matters look difficult, compromise is a good approach. Unfortunately, nature and the laws of physics cannot compromise - they are what they are.

Memories are not recycled like atoms and particles in quantum physics; they can be lost forever.

[There are, in us] possibilities that take our breath away, and show a world wider than either physics or philistine ethics can imagine. Here is a world in which all is well, in spite of certain forms of death, death of hope, death of strength, death of responsibility, of fear and wrong, death of everything that paganism, naturalism and legalism pin their trust on.

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 think the writing of literature should give pleasure. What else should it be about? It is not nuclear physics. It actually has to give pleasure or it is worth nothing.

My latter schooldays and my university days were during the war, when science - physics, in particular - was a very important and glamorous subject. A lot of us felt that if we couldn't get into science, we might try engineering or medicine.
