Physics Experiment Quotes & Sayings

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. — Erwin Schrodinger

Like the very quantum particles we study, we must be comfortable allowing our view of the world to exist in superposition. — Kevin Michel

Historians are not scientists. They cannot (and should not even trying to) establish universal laws of social or political "physics" with reliable predictive powers. Why? Because there is no possibility of repeating the single, multi-millennium experiment that constant to the past. The sample size of human history is one. — Niall Ferguson

In science's pecking order, evolutionary biology lurks somewhere near the bottom, far closer to phrenology than to physics. For evolutionary biology is a historical science, laden with history's inevitable imponderables. We evolutionary biologists cannot generate a Cretaceous Park to observe exactly what killed the dinosaurs; and, unlike "harder" scientists, we usually cannot resolve issues with a simple experiment, such as adding tube A to tube B and noting the color of the mixture. — Jerry A. Coyne

Sommerfeld's fine-structure theory was generally considered to be excellently and unambiguously confirmed by experiment. Because the theory rested on the foundation provided by Bohr, the experiments were also taken as strong support for his theory of atomic structure. — Helge Kragh

If you want to win this argument with Dad, look in chapter two of the first book of the Feynman Lectures on Physics. There's a quote there about how philosophers say a great deal about what science absolutely requires, and it is all wrong, because the only rule in science is that the final arbiter is observation - that you just have to look at the world and report what you see. Um ... off the top of my head I can't think of where to find something about how it's an ideal of science to settle things by experiment instead of arguments - — Eliezer Yudkowsky

There are many examples of old, incorrect theories that stubbornly persisted, sustained only by the prestige of foolish but well-connected scientists ... Many of these theories have been killed off only when some decisive experiment exposed their incorrectness.. Thus the yeoman work in any science, and especially physics, is done by the experimentalist, who must keep the theoreticians honest. — Michio Kaku

I do not think the division of the subject into two parts - into applied mathematics and experimental physics a good one, for natural philosophy without experiment is merely mathematical exercise, while experiment without mathematics will neither sufficiently discipline the mind or sufficiently extend our knowledge in a subject like physics. — Balfour Stewart

Science is not about making predictions or performing experiments. Science is about explaining. — Bill Gaede

To me, what makes physics physics is that experiment is intimately connected to theory. It's one whole. — Lene Hau

The main thesis of mind-physics holds that consciousness and matter are both manifestations of a more primary entity, and that the processes of manifestation exhibit equivalent invariances for both consciousness and matter. When the program for mind-physics is complete the subject-object dichotomy of modal logic, the polarity of concept-percept, and the antagonism between morality and technology will all come to an end. Then the non-repeatable experiment will be understood to be more primary than the traditional repeatable experiment. — Paul Laffoley

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 — Max Born

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. — Robert Andrews Millikan

There is plenty of room left for exact experiment in art, and the gate has been opened for some time. What had been accomplished in music by the end of the eighteenth century has only begun in the fine arts. Mathematics and physics have given us a clue in the form of rules to be strictly observed or departed from, as the case may be. Here salutary discipline is come to grips first of all with the function of forms, and not with form as the final result ... in this way we learn how to look beyond the surface and get to the root of things. — Paul Klee

Quantum physics is quite interesting. All these tiny particles are there as much as they're not there. That to me is very, very interesting. And how our thoughts change the outcome of an experiment, I think that's all quite spiritual. — Jerry Hall

Einstein does not remain attached to the classical principles, and when presented with a problem in physics he quickly envisages all of its possibilities. This leads immediately in his mind to the prediction of new phenomena which may one day be verified by experiment. — Henri Poincare

To doubt that life evolved, even if some of the details described in this book may yet prove wrong, is to doubt the convergence of evidence, from molecules to men, from bacteria to planetary systems. It is to doubt the evidence of biology, and its concordance with physics and chemistry, geology and astronomy. It is to doubt the veracity of experiment and observation, to doubt the testing in reality. It is, in the end, to doubt reality. — Nick Lane

The particles that are the very building blocks of all things, are in all possible locations until observation/measurement causes them to choose a specific position. — Kevin Michel

One of the various theories proposed to explain the negative result of the famous Michelson-Morley experiment with light waves (conceived to measure the absolute space), was based on the ballistic hypothesis, i.e. on postulating that the speed of light predicted by Maxwell's equations was not given as relative to the medium but as relative to the transmitter (firearm). Had that been the case, the experiment negative results would have not caused such perplexity and frustration (as we shall see in forthcoming sections). — Felix Alba-Juez

Geology differs from physics, chemistry, and biology in that the possibilities for experiment are limited. — Reinout Willem Van Bemmelen

The only object of theoretical physics is to calculate results that can be compared with experiment ... it is quite unnecessary that any satisfactory description of the whole course of the phenomena should be given. — Paul Dirac

In microphysics the observer interferes with the experiment in a way that can't be measured and that therefore can't be eliminated. No natural laws can be formulated, saying "such-and-such will happen in every case." All the microphysicist can say is "such-and-such is, according to statistical probability, likely to happen." This naturally represents a tremendous problem for our classical physical thinking. It requires a consideration, in a scientific experiment, of the mental outlook of the participant-observer: It could this be said that scientists can no longer hope to describe any aspects or qualities of outer objects in a completely independent, "objective" manner. — M.L. Von Franz

Any schoolboy can do experiments in the physics laboratory to test various scientific hypothesis. But man, because he has only one life to live, cannot conduct experiments to test whether to follow his passion or not. — Milan Kundera

Experiment is the sole judge of scientific "truth." But what is the source of knowledge? Where do the laws that are to be tested come from? Experiment, itself, helps to produce these laws, in the sense that it gives us hints. But also needed is imagination to create from these hints the great generalizations - to guess at the wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we have made the right guess. This imagining process is so difficult that there is a division of labor in physics: there are theoretical physicists who imagine, deduce, and guess at new laws, but do not experiment; and then there are experimental physicists who experiment, imagine, deduce, and guess. — Richard Feynman

The more we delve into quantum mechanics the stranger the world becomes; appreciating this strangeness of the world, whilst still operating in that which you now consider reality, will be the foundation for shifting the current trajectory of your life from ordinary to extraordinary. It is the Tao of mixing this cosmic weirdness with the practical and physical, which will allow you to move, moment by moment, through parallel worlds to achieve your dreams. — Kevin Michel

In the matter of physics, the first lessons should contain nothing but what is experimental and interesting to see. A pretty experiment is in itself often more valuable than twenty formulae extracted from our minds. — Albert Einstein

I'm doing physics because I'm curious about how it works - full speed ahead, damn the torpedoes, don't worry about whether somebody is going to be able to do an experiment next week, just figure it out. — Leonard Susskind

Winfree came from a family in which no one had gone to college. He got started, he would say, by not having proper education. His father, rising from the bottom of the life insurance business to the level of vice president, moved family almost yearly up and down the East Coast, and Winfree attended than a dozen schools before finishing high school. He developed a feeling that the interesting things in the world had to do with biology and mathematics and a companion feeling that no standard combination of the two subjects did justice to what was interesting. So he decided not to take a standard approach. He took a five-year course in engineering physics at Cornell University, learning applied mathematics and a full range of hands-on laboratory styles. Prepared to be hired into military-industrial complex, he got a doctorate in biology, striving to combine experiment with theory in new ways. — James Gleick

It will reward enough for me if, by the publication of the present experiment, I have directed the attention of investigators to this subject, which still promises much for physical optics and appears to open a new field. — Joseph Von Fraunhofer

What we observe is not nature itself but nature exposed to our method of questioning. Our scientific work in physics consists in asking questions about nature in the language that we possess and trying to get an answer from experiment by the means that are at our disposal. — Werner Heisenberg

In modern physics, there is no such thing as "nothing." Even in a perfect vacuum, pairs of virtual particles are constantly being created and destroyed. The existence of these particles is no mathematical fiction. Though they cannot be directly observed, the effects they create are quite real. The assumption that they exist leads to predictions that have been confirmed by experiment to a high degree of accuracy. — Richard Morris

There was, I think, a feeling that the best science was that done in the simplest way. In experimental work, as in mathematics, there was 'style' and a result obtained with simple equipment was more elegant than one obtained with complicated apparatus, just as a mathematical proof derived neatly was better than one involving laborious calculations. Rutherford's first disintegration experiment, and Chadwick's discovery of the neutron had a 'style' that is different from that of experiments made with giant accelerators. — John Ashworth Ratcliffe

Lester Germer was my first supervisor at Bell Labs. He was the Germer of the Davisson and Germer Experiment that is sometimes referred to in introductory texts on physics. — Willard Boyle

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. — Peter Higgs

An idea sparked in the 1960s, a thought experiment, an amusing haiku, is now a thing of metal and glass. — Janna Levin

There are many hypotheses in physics of almost comparable brillance and elegance that have been rejected because they did not survive such a confrontation with experiment. In my view, the human condition would be greatly improved if such confrontations and willingness to reject hypotheses were a regular part of our social, political, economic, religious and cultural lives. — Carl Sagan

Unless the structure of the nucleus has a surprise in store for us, the conclusion seems plain-there is nothing in the whole system if laws of physics that cannot be deduced unambiguously from epistemological considerations. An intelligence, unacquainted with our universe, but acquainted with the system of thought by which the human mind interprets to itself the contents of its sensory experience, and should be able to attain all the knowledge of physics that we have attained by experiment. — Arthur Eddington

Mister Geoffrey, my experiment shows that the dynamo and the bulb are both working properly," I said. "So why won't the radio play?"
"I don't know," he said. "Try connecting them here."
He was pointing toward a socket on the radio labeled "AC," and when I shoved the wires inside, the radio came to life. We shouted with excitement. As I pedaled the bicycle, I could hear the great Billy Kaunda playing his happy music on Radio Two, and that made Geoffrey start to dance.
"Keep pedaling," he said. "That's it, just keep pedaling."
"Hey, I want to dance, too."
"You'll have to wait your turn."
Without realizing it, I'd just discovered the difference between alternating and direct current. Of course, I wouldn't know what this meant until much later.
After a few minutes of pedaling this upside-down bike by hand, my arm grew tired and the radio slowly died. So I began thinking, "What can do the pedaling for us so Geoffrey and I can dance? — William Kamkwamba
