Quotes & Sayings About Physics Experiments

In physics, opinions don't matter, only demonstrated experiments. The day the fellow succeeds, if ever, he won't need anybody else's opinion. — Neil DeGrasse Tyson

The physicist may be satisfied when he has the mathematical scheme and knows how to use for the interpretation of the experiments. But he has to speak about his results also to non-physicists who will not be satisfied unless some explanation is given in plain language. Even for the physicist the description in plain language will be the criterion of the degree of understanding that has been reached.
Physics and Philosophy — Werner Heisenberg

If physics leads us today to a world view which is essentially mystical, it returns, in a way, to its beginning, 2,500 years ago ... This time, however, it is not only based on intuition, but also on experiments of great precision and sophistication, and on a rigorous and consistent mathematical formalism. — Fritjof Capra

During the time that Landsteiner gave me an education in the field of immunology, I discovered that he and I were thinking about the serologic problem in very different ways. He would ask, What do these experiments force us to believe about the nature of the world? I would ask, What is the most. simple and general picture of the world that we can formulate that is not ruled by these experiments? I realized that medical and biological investigators were not attacking their problems the same way that theoretical physicists do, the way I had been in the habit of doing. — Linus Pauling

Insofar as he makes use of his healthy senses, man himself is the best and most exact scientific instrument possible. The greatest misfortune of modern physics is that its experiments have been set apart from man, as it were, physics refuses to recognize nature in anything not shown by artificial instruments, and even uses this as a measure of its accomplishments. — Johann Wolfgang Von Goethe

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. — Wietse Venema

Classical physics has been superseded by quantum theory: quantum theory is verified by experiments. Experiments must be described in terms of classical physics. — Carl Friedrich Von Weizsacker

When you read about chemistry and physics, you want to do them too. — Robert A. Heinlein

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

I think it's science and physics are just starting to learn from all these experiments. These experiments have been carried out hundreds and hundreds of times in all sorts of ways that no physicist really questions the end point. I think that these experiments are very clearly telling us that consciousness is limitless and the ultimate reality. — Robert Lanza

I remember discussions with Bohr which went through many hours till very late at night and ended almost in despair; and when at the end of the discussion I went alone for a walk in the neighbouring park I repeated to myself again and again the question: Can nature possibly be so absurd as it seemed to us in these atomic experiments? — Werner Heisenberg

There are physicists, and there are string theorists. Of course the string theorists are physicists, but the string theorists in general will not attend lectures on experimental physics. They will not be terribly concerned about the results of experiments. They will talk to one another. — Sheldon Lee Glashow

The dogma of the impossibility of determining the atomic constitution of substances, which until recently was advocated with such fervor by the most able chemists, is beginning to be abandoned and forgotten; and one can predict that the day is not far in the future when a sufficient collection of facts will permit determination of the internal architecture of molecules. A series of experiments directed toward such a goal is the object of this paper. — Wilhelm Korner

When one studies strongly radioactive substances special precautions must be taken if one wishes to be able to take delicate measurements. The various objects used in a chemical laboratory and those used in a chemical laboratory, and those which serve for experiments in physics, become radioactive in a short time and act upon photographic plates through black paper. Dust, the air of the room, and one's clothes all become radioactive. — Marie Curie

Recent scientific experiments in quantum physics have shed enormous light on how this world might function and have confirmed beliefs by early quantum physicists that light is not the fastest moving particle. That information at the quantum level passes instantaneously, and thus is infinitely faster. — Newton Fortuin

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

Einstein's discovery of special relativity involved an intuition based on a decade of intellectual as well as personal experiences.9 The most important and obvious, I think, was his deep understanding and knowledge of theoretical physics. He was also helped by his ability to visualize thought experiments, which had been encouraged by his education in Aarau. Also, there was his grounding in philosophy: from Hume and Mach he had developed a skepticism about things that could not be observed. And this skepticism was enhanced by his innate rebellious tendency to question authority. — Walter Isaacson

In the pursuit of my investigations I was unconsciously led into the border region of physics and physiology. To my amazement, I found boundary lines vanishing, and points of contact emerging, between the realms of the living and the non-living. Inorganic matter was perceived as anything but inert; it was athrill under the action of multitudinous forces. A universal reaction seemed to bring metal, plant and animal under a common law. They all exhibited essentially the same phenomena of fatigue and depression, with possibilities of recovery and of exaltation, as well as the permanent irresponsiveness associated with death. Filled with awe at this stupendous generalization, it was with great hope that I announced my results before the Royal Society - results demonstrated by experiments. — Paramahansa Yogananda

That's absolutely correct and in addition to that life just isn't an accident of the laws of physics. There's a long list of experiments that suggest just the opposite. — Robert Lanza

It is tribute to how far we have come in theoretical physics that it now takes enormous machines and a great deal of money to perform experiments whose results we can not predict. — Stephen Hawking

I tried out various experiments described in treatises on physics and chemistry, and the results were sometimes unexpected. At times, I would be encouraged by a little unhoped-for success; at others, I would be in the deepest despair because of accidents and failures resulting from my inexperience. — Marie Curie

A mathematician is an individual who calls himself a 'physicist' and does 'physics' and physical experiments with abstract concepts. — Bill Gaede

There are relatively few experiments in atomic physics these days that don't involve the use of a laser. — Eric Allin Cornell

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

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. — Udny Yule

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. — Reinout Willem Van Bemmelen

He (Comings) has in the past performed successful energy-converting experiments, creating a ringing resonance by injecting certain frequencies into piezo-electric crystals. When the crystal was in resonance with the plenum of space, the power output rose significantly higher than the input. He concluded that, if allowed politically, such discoveries could guide humankind in building a completely clean energy infrastructure -- resonant technologies that allow us to live in harmony with the universal energy field and the Earth. — Jeane Manning

Erwin Schrodinger has explained how he and his fellow physicists had agreed that they would report their new discoveries and experiments in quantum physics in the language of Newtonian physics. That is, they agreed to discuss and report the non-visual, electronic world in the language of the visual world of Newton. — Marshall McLuhan

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

Laser cooling opened a new route to ultralow temperature physics. Laser cooling experiments, with room temperature vacuum chambers and easy optical access, look very different from cryogenic cells with multi-layer thermal shielding around them. — Wolfgang Ketterle

Chemistry, until my childhood, not that long ago, was regarded as a calculating device. Because you couldn't reduce to physics. So it's just some way of calculating the result of experiments. The Bohr atom was treated that way. — Noam Chomsky

All the quantum physics experiments have occurred chiefly on the atomic scale and we are taught to believe that nature's laws are consistent. — Mitch Horowitz

Through experiments over the past few decades physicists have discovered matter to be completely mutable into other particles or energy and vice-versa and on a subatomic level, matter does not exist with certainty in definite places, but rather shows 'tendencies' to exist. Quantum physics is beginning to realise that the Universe appears to be a dynamic web of interconnected and inseparable energy patterns. If the universe is indeed composed of such a web, there is logically no such thing as a part. This implies we are not separated parts of a whole but rather we are the Whole. — Barbara Brennan

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
