Top 1200 Theoretical Physics Quotes & Sayings - Page 3

The development of physics in the twentieth century already has transformed the consciousness of those involved with it. The study (of modern physics) produces insights into the nature of reality very similar to those produced by the study of eastern philosophy.

The problem of physics is how the actual phenomena, as observed with the help of our sense organs aided by instruments, can be reduced to simple notions which are suited for precise measurement and used of the formulation of quantitative laws. Experiment and Theory in Physics

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.

Physics is often stranger than science fiction, and I think science fiction takes its cues from physics: higher dimensions, wormholes, the warping of space and time, stuff like that.

My degrees are in physics and space physics, and I did well enough in university that I actually started working at the Johnson Space Center in Houston, Texas, as a robotics flight controller right after college.

There are 15 main theories in physics, and we know all of them. If there weren't a finite number of theories, there would not be a point to 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.

But curriculum-wise, I was drawn to the sciences and specifically to physics, and I really enjoyed it and I think for a little while there, I was really thinking my schooling would be in physics, that that was something I loved.

We get the exciting result that the total energy of the universe is zero. Why this should be so is one of the great mysteries - and therefore one of the important questions of physics. After all, what would be the use of studying physics if the mysteries were not the most important things to investigate?

The problem is that modern fundamental physics is so far from you and me. The mathematics has become so much more complicated that you need at least 10 years to understand it. Fundamental physics has advanced so far from the understanding of most people that there is really a big disconnect.

As physics students, we are taught that physicists are smart, that chemists are moderately acceptable, and that biologists are certainly not very intelligent. So I wasn't inclined to take a biology course. But my father insisted, and maybe what he had in mind was that, if there were no jobs in physics, I would end up being a doctor.

In 1948 I entered the Massachusetts Institute of Technology, undecided between studies of chemistry and physics, but my first year convinced me that physics was more interesting to me.

It has long been my personal view that the separation of practical and theoretical work is artificial and injurious. Much of the practical work done in computing, both in software and in hardware design, is unsound and clumsy because the people who do it have not any clear understanding of the fundamental design principles of their work. Most of the abstract mathematical and theoretical work is sterile because it has no point of contact with real computing.

Certainly to me it has been valuable to have to think through the basics of physics in order to present them in a halfway coherent form for a course. That has led me to ideas in research. Even freshman physics leads to thoughts that lead to other thoughts that are stimulating.

My physics teacher, Thomas Miner was particularly gifted. To this day, I remember how he introduced the subject of physics. He told us we were going to learn how to deal with very simple questions such as how a body falls due to the acceleration of gravity.

From a consideration of the immense volume of newly discovered facts in the field of physics, especially atomic physics, in recent years it might well appear to the layman that the main problems were already solved and that only more detailed work was necessary.

Would physics at Geneva be as good as physics at Harvard? I think not. Rome? I think not. In Britain, I don't think there is one place, neither Cambridge nor Oxford, which can compare with Harvard.

The parts of physics that are exact are the parts of physics that are exact. The parts that are inexact are vastly greater. Sensible scientists don't waste their time pushing against doors that endlessly will not give. They are opportunistic and go where they can, but there are pitfalls in that.

In A Brief History Of Time I used the word "God" like Einstein did as a shorthand for the laws of physics. However, this is not what most people mean by God, so I have decided not to use the term. The laws of physics can explain the universe without the need for a God.

So far I have been speaking of theoretical science, which is an attempt to understand the world. Practical science, which is an attempt to change the world, has been important from the first, and has continually increased in importance, until it has almost ousted theoretical science from men's thoughts.

It's physics. Pure physics, I'm falling fast and faster still. So fall with me. Fall down with me. And stay.

The first rule of world-building is available physics, which basically means that if you want it to feel real, it has to follow the same rules as this world, from gravity to how human behaviour works. If you have a fantasy element that doesn't obey the laws of physics, make sure that it has a fantasy explanation.

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.

If I want to understand the laws of physics I have to first believe what I read about physics. I have to have faith in what I read.

Physics is very muddled again at the moment; it is much too hard for me anyway, and I wish I were a movie comedian or something like that and had never heard anything about physics!

The real negotiation is between humans on the one hand and chemistry and physics on the other. And chemistry and physics, unfortunately, don't bargain.

Before the discovery of quantum mechanics, the framework of physics was this: If you tell me how things are now, I can then use the laws of physics to calculate, and hence predict, how things will be later.

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 if life after death is all based within memory: you die, and you don't ascend on a bed of clouds to Jesus, but your brain has a terrain that it can use to propel itself further. It's more of a theoretical afterlife. If that's true, all of these theoretical afterlives of people could potentially interact or network. That space seems way more powerful and exciting than reality. This potential boundlessness is more of what god is to me.

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 .

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.

I think I always wanted to go into physics. What always fascinated me about science was the desire to understand what underlies it all, and I think physics is basically the study of that.

So much of what we said sounded crazy, yet none of it was false... as if two theoretical physicists stood on stage to say that when we travel near lightspeed, we get younger than nontravellers; that a mile of space next to the sun is differnt than a mile of space next to the earth because the sun-mile space is curved more than the the earth-mile. Silly ideas, worth the admission price in smiles, but they're true. Is high-energy physics interesting because it's true or because it's crazy?

There are some countries where there is not an issue with women in physics. Malaysia, for example, has physics departments where 60 per cent of undergraduates are female, and France and Italy are strong, too. It is not about ability but more about what the culture says is appropriate.

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.

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, however, want to become those we are--human beings who are new, unique, incomparable, who give themselves laws, who create themselves. To that end we must become the best learners and discoverers of everything that is lawful and necessary in the world: we must become physicists in order to be able to be creators in this sense--while hitherto all valuations and ideals have been based on ignorance of physics or were constructed so as to contradict it. Therefore: long live physics! And even more so that which compels us to turn to physics--our honesty!

There is not a soul on Earth who can read the deluge of physics publications in its entirety. As a result, it is sad but true that physics has irretrievably fallen apart from a cohesive to a fragmented discipline. ... It was not that long ago that people were complaining about two cultures. If we only had it that good. today.

I read a book called 'The Tao of Physics' by Fritjof Capra that pointed out the parallels between quantum physics and eastern mysticism. I started to feel there was more to reality than conventional science allowed for and some interesting ideas that it hadn't got round to investigating, such as altered states of consciousness.

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

It's interesting to see what's going on with physics these days because they're starting to come out with stuff that sounds remarkably like Buddhism and even more specifically like the ancient Hindu Vedas. Physics isn't necessarily saying the exact same thing but I think eventually it will merge.

According to my views, aiming at quantitative investigations, that is at establishing relations between measurements of phenomena, should take first place in the experimental practice of physics. By measurement to knowledge [door meten tot weten] I should like to write as a motto above the entrance to every physics laboratory.

My high school career was undistinguished except for math and science. However, having barely been admitted to Rice University, I found that I enjoyed the courses and the elation of success and graduated with honors in physics. I did a senior thesis with C.F. Squire, building a regulator for a magnet for use in low-temperature physics.

So, economics should emulate physics' basic ethos, but its search for precision in physics-like formulas is almost always wrong in economics.

It's as if we think the laws of physics are subject to debate and amendment and political contributions can sway the laws of physics.

Mathematics is a part of physics. Physics is an experimental science, a part of natural science. Mathematics is the part of physics where experiments are cheap.

I had an excellent math and physics teacher in high school named T.C. Patel, and in the university, I had truly dedicated professors in both physics and mathematics who gave me a sound foundation with which to pursue graduate studies.

My father worked in high-energy nuclear physics, and my mother was a mycologist and a geneticist. After both parents completed postdoctoral fellowships in San Diego in 1962, my father took a faculty position in the Physics Department at Yale, and so the family moved to New Haven, Connecticut.

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.

I became an atheist because, as a graduate student studying quantum physics, life seemed to be reducible to second-order differential equations. Mathematics, chemistry and physics had it all. And I didn't see any need to go beyond that.

The truth was, there were four partners in our marriage. Stephen and me, motor neurone disease, and physics. If you took out motor neurone disease, you are still left with physics.

As for me, I want to have fun while I'm working. Now not everyone thinks physics is fun, but I do. I think experimental physics is especially fun, because not only do you get to solve puzzles about the universe or on Earth, there are really cool toys in the lab.

A second possible approach to general systems theory is through the arrangement of theoretical systems and constructs in a hierarchy of complexity, roughly corresponding to the complexity of the "individuals" of the various empirical fields... leading towards a "system of systems." [...] I suggest below a possible arrangement of "levels" of theoretical discourse...(vi) [...] the "animal" level, characterized by increased mobility, teleological behavior and self-awareness...

The laws of Congress and the laws of physics have grown increasingly divergent, and the laws of physics are not likely to yield.

I don't have the Big Idea. I don't have the arrogance to even want to have the Big Idea. But I believe the physics of resisting power is as old as the physics of accumulating power. That's what keeps the balance in the universe... the refusal to obey.

I may have made a straight A in physics, but I was panic-struck. Physics made me sick the whole time I learned it.

I thought physics could be done to the glory of God, till I saw there wasn’t any God at all and that physics was more interesting anyway. The Christian religion is a very powerful and convincing mistake, that’s all.

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.

Physics is an organized body of knowledge about nature, and a student of it says that he is learning physics, not nature. Art, like nature, has to be distinguished from the systematic study of it, which is criticism.

Whenever I want to represent or depict the official version, I will refer to them as 'mathematicians' or 'mathematical physicists' or idiots or something like that. There are no physicists in mainstream 'Physics.' From Newton to Einstein to Hawking, they are all just mathematicians as far as Science and Physics are concerned.
