Physics Quotes

Experiments in geology are far more difficult than in physics and chemistry because of the greater size of the objects, commonly outside our laboratories, up to the earth itself, and also because of the fact that the geologic time scale exceeds the human time scale by a million and more times. This difference in time allows only direct observations of the actual geologic processes, the mind having to imagine what could possibly have happened in the past Picture Quote #1

Students using astrophysical textbooks remain essentially ignorant of even the existence of plasma concepts, despite the fact that some of them have been known for half a century. The conclusion is that astrophysics is too important to be left in the hands of astrophysicists who have gotten their main knowledge from these textbooks. Earthbound and space telescope data must be treated by scientists who are familiar with laboratory and magnetospheric physics and circuit theory, and of course with modern plasma theory Picture Quote #1

If the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics Picture Quote #1

The great problem of today is, how to subject all physical phenomena to dynamical laws. With all the experimental devices, and all the mathematical appliances of this generation, the human mind has been baffled in its attempts to construct a universal science of physics Picture Quote #1

The investigation of causal relations between economic phenomena presents many problems of peculiar difficulty, and offers many opportunities for fallacious conclusions. Since the statistician can seldom or never make experiments for himself, he has to accept the data of daily experience, and discuss as best he can the relations of a whole group of changes; he cannot, like the physicist, narrow down the issue to the effect of one variation at a time. The problems of statistics are in this sense far more complex than the problems of physics Picture Quote #1

... while there is such a thing as correctness in ethics, in interpretation, in mathematics, the way to understand that is not by trying to model it on the ways in which we get things right in physics Picture Quote #1

The key to teaching anything is to remember what it was like not to understand that thing. That’s a very hard thing to do. Every time you come to understand something you didn’t understand before, you are transformed. You become a different person from who you were before. The key to teaching someone else to understand that same thing is to remember your former, untransformed self. If you can do that, I think you can teach anything, even physics Picture Quote #1

Now we see evolutionary trends in a variety of areas ranging from atomic and molecular physics through fluid mechanics, chemistry and biology to large scale systems of relevance in environmental and economic sciences Picture Quote #1

The beauty of physics lies in the extent which seemingly complex and unrelated phenomena can be explained and correlated through a high level of abstraction by a set of laws which are amazing in their simplicity Picture Quote #1

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 Picture Quote #1

The determination of the average man is not merely a matter of speculative curiosity; it may be of the most important service to the science of man and the social system. It ought necessarily to precede every other inquiry into social physics, since it is, as it were, the basis. The average man, indeed, is in a nation what the centre of gravity is in a body; it is by having that central point in view that we arrive at the apprehension of all the phenomena of equilibrium and motion Picture Quote #1

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 Picture Quote #1

Physics advances by accepting absurdities. Its history is one of unbelievable ideas proving to be true Picture Quote #1

And within the world that you’ve created, the physics of that world have to remain constant; they can’t be amorphous and changing Picture Quote #1

The physics chip adds a level of reality in games we just haven’t been able to get Picture Quote #1

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 Picture Quote #1

Modern physics had shown that the rhythm of creation and destruction is not only manifest in the turn of the seasons and in the birth and death of living creatures, but is also the very essence of inorganic matter. For modern physicists... Shiva’s dance is the dance of subatomic matter Picture Quote #1

That which is not measurable is not science. That which is not physics is stamp collecting Picture Quote #1

The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation Picture Quote #1

We have a closed circle of consistency here: the laws of physics produce complex systems, and these complex systems lead to consciousness, which then produces mathematics, which can then encode in a succinct and inspiring way the very underlying laws of physics that gave rise to it Picture Quote #1

How can you be a physics major and be shocked when you get pregnant from having sex? Picture Quote #1

When I run, I think about everything: physics, family problems, plans for the weekend. I haven’t made any big discoveries on a run, but it does give me time to think through problems. Some solutions are obvious, but they are only obvious when you are relaxed enough to find them Picture Quote #1

My wish is to construct a system of sociology on the model of celestial mechanics, physics, and chemistry Picture Quote #1

Everyone now agrees that a physics lacking all connection with mathematics... would only be an historical amusement, fitter for entertaining the idle than for occupying the mind of a philosopher Picture Quote #1

By far the most important consequence of the conceptual revolution brought about in physics by relativity and quantum theory lies not in such details as that meter sticks shorten when they move or that simultaneous position and momentum have no meaning, but in the insight that we had not been using our minds properly and that it is important to find out how to do so Picture Quote #1

Computer science is to biology what calculus is to physics. It’s the natural mathematical technique that best maps the character of the subject Picture Quote #1

So far as physics is concerned, time’s arrow is a property of entropy alone Picture Quote #1

In the world of physics we watch a shadowgraph performance of the drama of familiar life. The shadow of my elbow rests on the shadow table as the shadow ink flows over the shadow paper. It is all symbolic, and as a symbol the physicist leaves it... The frank realization that physical science is concerned with a world of shadows is one of the most significant of recent advances Picture Quote #1

The laws of physics... seem to be the product of exceedingly ingenious design... The universe must have a purpose Picture Quote #1

One thing they don’t tell you about doing experimental physics is that sometimes you must work under adverse conditions... like a state of sheer terror Picture Quote #1
