Physics Quotes

“Although I was really interested in physics, I think I wanted to do it because I thought it was really hard. I did theoretical physics.”

“I have a problem with telling jokes about physics. Quite often the audience have no idea what you are talking about and, to be honest, I don't know what I'm talking about either.”

“How can a man be still if he sees such a great wrong being instigated?''It's difficult, but it's necessary,' Professor While insisted. 'Science must go on unhindered, and if we bring politics into our work we will cease to be scientists.''Will we cease being human?' MacGregor demanded with the rudeness of justifying himself. 'Should we hand over our affairs to men we despise?''I suppose that is unanswerable.' Professor White was an deep into it now as MacGregor. 'But when we dabble in politics we suffer what you are suffering now, and it isn't worth it. Is it?''I don't know,' MacGregor said morosely.'Then why destroy yourself?' 'I don't believe a man has much choice any more,' MacGregor said. 'There seems to be some kind of a battle going on for any existence, science and all.''You may be right,' the Professor said. 'We are certainly facing a situation of terrible choice. Only yesterday the physicist chaps back from America brought in a petition to sign against control and secrecy of information and research in nuclear physics. Once they start on this secrecy business there is no telling where it will end. It was bad enough when we were working at Tennessee. We cannot have those ignorant politicians telling us what we must do.''They are already telling us what we must do,' MacGregor argued. 'The military control so much research that the phyusicist are becoming straight-out weapon makers and nothing else.''It's not the physicists' fault...''Then why don't they stop working for the military. Now they are talking about radio-active dust clouds and the biologists are producing concentrates of bacteria for wholesale disease-making. What's the matter with them? Have the Generals got them so scared that they meekly do as they are told?''Weapons are a part of life,' the Professor commented sadly, 'and since the politicians refuse to be peaceful, at least they ask for weapons and give us a chance we would not otherwise have of making enormous strides in costly research.''Perhaps. But don't we care how the products of our research are used?''You are looking for logic where there isn't any,' the Professor said. 'It isn't science which shapes the world, young man.''No sir, but we are part of it.''Really a very small part of it. The ultimate decision on human affairs lies outside science. We may be part of it, but if you are looking for the deciding factor in the shape of existence then I don't know where you'll find it.”

“In a previous life I wrote the software that controlled my physics experiments. That software had to deal with all kinds of possible failures in equipment. That is probably where I learned to rely on multiple safety nets inside and around my systems.”

“It would seem that I, who never could make much sense of physics when I was at school, have now gained a strong sense of Einsteinian space-time. I am free of the nimbyism of now, and feel a strong kinship with both the dead and the unborn.”

“From the point of view of basic physics, the most interesting phenomena are, of course, in the new places, the places where the rules do not work - not the places where they do work! That is the way in which we discover new rules.”

“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.”

“If you understand physics of how a locomotive works, that knowledge is irreplaceable.”

“I'm not a geius guy, even and Albert Einstein isn't and Tesla, nobody is genius. From where you will know what's the IQ for Albert or Tesla in their time there wasn't such test and how such test can show how clever are you in case that the most questions are math, physics and mainly this how this two subjects will show that you are clever or dumb?? I strongly doubt about this if I know the answer sof the test and I fill it right so I must be the world clever man? No, I don't think so - That's bullshit!That I have written 8 books and now I'm working on some other books this doesn't make me clever, the most stuff are just search from the internet and put, the other is thoughts from me. Like thinking on some questions and that's all!”

“Laws of physics don't necessarily apply to real-life political situations.”

“I'm a person who's very interested in science and the universe and quantum physics and astrophysics.”

“Indubitably, magic is one of the subtlest and most difficult of the sciences and arts. There is more opportunity for errors of comprehension, judgment and practice than in any other branch of physics.”

“Keep in mind that if you take a tour through a hospital and look at every machine with on and off switch that is brought into the service of diagnosing the human condition, that machine is based on principles of physics discovered by a physicist in a machine designed by an engineer.”

“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.”

“In string theory, all particles are vibrations on a tiny rubber band; physics is the harmonies on the string; chemistry is the melodies we play on vibrating strings; the universe is a symphony of strings, and the 'Mind of God' is cosmic music resonating in 11-dimensional hyperspace.”

“The human element and human judgment around understanding the physics of machines and the process, and how those come together, I think there's going to be a balance we all need to figure out how to strike.”

“We absolutely must leave room for doubt or there is no progress and there is no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty. People are terrified — how can you live and not know? It is not odd at all. You only think you know, as a matter of fact. And most of your actions are based on incomplete knowledge and you really don't know what it is all about, or what the purpose of the world is, or know a great deal of other things. It is possible to live and not know.”

“To understand this new frontier, I will have to try to master one of the most difficult and counterintuitive theories ever recorded in the annals of science: quantum physics. Listen to those who have spent their lives immersed in this world and you will have a sense of the challenge we face. After making his groundbreaking discoveries in quantum physics, Werner Heisenberg recalled, "I repeated to myself again and again the question: Can nature possibly be so absurd as it seemed to us in these atomic experiments?" Einstein declared after one discovery, "If it is correct it signifies the end of science." Schrödinger was so shocked by the implications of what he'd cooked up that he admitted, "I do not like it and I am sorry I had anything to do with it." Nevertheless, quantum physics is now one of the most powerful and well-tested pieces of science on the books. Nothing has come close to pushing it off its pedestal as one of the great scientific achievements of the last century. So there is nothing to do but to dive headfirst into this uncertain world. Feynman has some good advice for me as I embark on my quest: "I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possibly avoid it, 'But how can it be like that?' because you will get 'down the drain,' into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.”

“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.”

“Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle. String theory does so again because a point particle is replaced by a string, which is more spread out.”
