Top 1200 Quantum Physics Quotes & Sayings - Page 20

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.

I do find that Western medicine is more and more open to proving energetic concepts. Why not, because modern physics is 100 percent based on it.

It was at this moment that I wrote my first important paper in theoretical physics. I was 32 years old, 5 years beyond the alleged age of senility for theorists.

My undergraduate degree was in history, and I wish I had been smart enough to really excel at maths, physics, chemistry or biology because... the voyagers and adventurers and real contributors - that's where they come from.

Whether you function as welders or inspectors, the laws of physics are implacable lie-detectors. You may fool men. You will never fool the metal.

No. I had successfully solved the difficulty of finding a description of the electron which was consistent with both relativity and quantum mechanics. Of course, when you solve one difficulty, other new difficulties arise. You then try to sove them. You can never solve all difficulties at once.

My recollection of the higher school certificate, which involved a practical exam in physics, was being confronted with an experiment involving a sort of barometer arrangement, wondering why I couldn't make it work.

There can be no final truth in ethics any more than in physics, until the last man has had his experience and said his say.

When you look at the calculation, it's amazing that every time you try to prove or disprove time travel, you've pushed Einstein's theory to the very limits where quantum effects must dominate. That's telling us that you really need a theory of everything to resolve this question. And the only candidate is string theory.

Consequently he who wishes to attain to human perfection, must therefore first study Logic, next the various branches of Mathematics in their proper order, then Physics, and lastly Metaphysics.

I have always believed that astrophysics should be the extrapolation of laboratory physics, that we must begin from the present universe and work our way backward to progressively more remote and uncertain epochs.

Physics is nothing but the ABC's. Nature is an equation with an unknown, a Hebrew word which is written only with consonants to which reason has to add the dots.

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.

I think my father, who was Chinese, basically felt if we didn't major in science, we would starve on the streets, so we all went into science unquestioningly. I kind of faked my way through physics.

In relativity, movement is continuous, causally determinate and well defined, while in quantum mechanics it is discontinuous, not causally determinate and not well defined.

McMaster had an engineering physics program and... one of the parts of it was lasers and electro-optics and I just said, 'Now doesn't that sound cool. I just got to do that.'

It always seems odd to me that the fundamental laws of physics, when discovered, can appear in so many different forms that are not apparently identical at first, but, with a little mathematical fiddling, you can show the relationship.

Fields make huge progress when they move from stories (e.g Icarus) and authority (e.g 'witch doctor') to evidence/experiment (e.g physics, wind tunnels) and quantitative models (e.g design of modern aircraft).

In the progressive growth of astronomy, physics or mechanical science was developed, and when this had been, to a certain degree, successfully cultivated, it gave birth to the science of chemistry.

The prediction of nuclear winter is drawn not, of course, from any direct experience with the consequences of global nuclear war, but rather from an investigation of the governing physics.

Julian Assange is self-consciously an individual. He thinks in his own way, primarily as a physicist, having studied pure maths and physics at university in Australia where he grew up.

There happen to be a lot of people around who spent an hour on the Internet and think they know a lot of physics, but it doesn't work like that... There's a reason there are graduate schools in these departments.

As Stephen's fame began to take off in a big way, and because he was so immersed in physics, it was becoming more and more difficult to communicate with him.

Bertrand Russell had given a talk on the then new quantum mechanics, of whose wonders he was most appreciative. He spoke hard and earnestly in the New Lecture Hall. And when he was done, Professor Whitehead, who presided, thanked him for his efforts, and not least for 'leaving the vast darkness of the subject unobscured'.

It is now quite lawful for a Catholic woman to avoid pregnancy by a resort to mathematics, though she is still forbidden to resort to physics or chemistry.

I actually think that bass is probably the instrument that has evolved in a quantum leap compared to other instruments. It's the instrument that's evolved the most, especially with how it's perceived. And even how it's played, and how it's viewed from a point of view of commerce, like with the music industry.

In 1955, I got my degree in electrical-mechanical engineering. I realised, however, that my interest was less in practical applications than in the understanding of the underlying theoretical structure, and I decided to learn physics.

I was a very good student. But I didn't have the latitude to study more. I was never allowed to do anything cross-disciplinary. Why can't an engineering student learn physics?

The remarkable feature of physical laws is that they apply everywhere, whether or not you choose to believe in them. After the laws of physics, everything else is opinion.

We have lived in a world where the discoveries of physics and genetics are far more awe-inspiring, as well as infinitely more liberating, than the claims of any religion.

When modern physics exerts itself to establish the world's formula, what occurs thereby is this: the being of entities has resolved itself into the method of the totally calculable.

If the laws of physics be for us, who can be against us?!

We're cognizant, curious beings, capable of philosophical thought, nuclear physics, repeating Nerf weapons, global consciousness, Glade air fresheners, and sentient automobiles. But we're assholes first.

When it turned out that he could, Karou dropped to her knees to genuflect. "Gods of math and physics," she intoned, "I accept your gift of this clever fair-haired boy

Don't look at prayer as me asking God to give me something, like some type of cosmic bell captain, look at prayer as my communication with the quantum intelligence, the divine intelligence that we have out there and that is how things are manifested.

My mom studied biology and my dad studied chemistry and some physics and he is a physician, but he had a very strong interest in astronomy and astrophysics and exploration in general.

If you assume continuity, you can open the well-stocked mathematical toolkit of continuous functions and differential equations, the saws and hammers of engineering and physics for the past two centuries (and the foreseeable future).

For her PhD, Maria Goeppert Mayer, a theoretical physicist, came up with the idea of multi-photon physics. That means an atom absorbs two or more photons simultaneously.

Most of what Einstein said and did has no direct impact on what anybody reads in the Bible. Special relativity, his work in quantum mechanics, nobody even knows or cares. Where Einstein really affects the Bible is the fact that general relativity is the organizing principle for the Big Bang.

I look back upon graduate school as being a very happy period in my life. The chance to be thoroughly immersed in physics and to be surrounded by friends pursuing similar goals was a marvelous experience.

Louis Armstrong is quite simply the most important person in American music. He is to 20th century music (I did not say jazz) what Einstein is to physics.

I think we all change each other's paths. I don't know which law idea that is in physics, but I don't think any of us can live without affecting one another.

Today's particle physics describe light as a crumple in space, and we may have deformed space in such a way that they noticed something peculiar - and they had the ability to investigate it.

According to quantum field theory, fields alone are real. They are the substance of the universe and not 'matter'. Matter is simply the momentary manifestation of interacting fields which, intangible and insubstantial as they are, are the only real things in the universe.

String theory?[pause] It closed the conceptual gulp between relativity and quantum mechanics. It postulates that subatomic particles are not points, but strings, about one planck length long. The rate at which strings vibrate can generate the properties of all known particles. Huh? How did I know that?

I find enough mystery in mathematics to satisfy my spiritual needs. I think, for example, that pi is mysterious enough (don't get me started!) without having to worry about God. Or if pi isn't enough, how about fractals? or quantum mechanics?

This is absolutely correct and forms part of the larger concept that top-down causation is a key factor not just in the way the brain works but in broader contexts in biology and even physics.

In physics we have developed models that are extremely accurate across vastly different scales from the sub-atomic to the visible universe. In politics we have bumbled along making the same sort of errors repeatedly.

There is a physics to the world, which non-fiction has a contract to stand in awe of, otherwise it becomes completely self-centered and ego-driven, which is the death of a memoir.

Chemistry has been termed by the physicist as the messy part of physics, but that is no reason why the physicists should be permitted to make a mess of chemistry when they invade it.

We're always, by the way, in fundamental physics, always trying to investigate those things in which we don't understand the conclusions. After we've checked them enough, we're okay.

It is unnecessary to understand electromagnetic theory before wiring a lamp or to study physics in order to repair a pump. We count on our fingers and give no heed to the proliferating implications of the act.

To me music is the sound of nature in process, either the full cacophony, one thread of it, or a deliberate composition. It's both expressive and causal and can organize reality atmosphere like a law of physics.

They're hitting harder now more than ever. The only person who would argue that is someone who has never had a physics class. They're faster and stronger, so the reality is the collisions have to be bigger.

Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.

When you do calculations using quantum mechanics, even when you are calculating something perfectly sensible like the energy of an atomic state, you get an answer that is infinite. This means you are wrong - but how do you deal with that? Is there something wrong with the theory, or something wrong with the way you are doing the calculation?

The fundamental principle of human action, the law, that is to political economy what the law of gravitation is to physics is that men seek to gratify their desires with the least exertion

I entered the Physics Department in 1950, receiving a Master's degree in 1953 and a Ph.D. in 1956. It is difficult to convey the sense of excitement that pervaded the Department at that time.

When the weather changes, nobody believes the laws of physics have changed. Similarly, I don't believe that when the stock market goes into terrible gyrations its rules have changed.

It seems sensible to discard all hope of observing hitherto unobservable quantities, such as the position and period of the electron... Instead it seems more reasonable to try to establish a theoretical quantum mechanics, analogous to classical mechanics, but in which only relations between observable quantities occur.
