Atomic Physics Quotes

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

Using the word much as it is used in atomic physics to characterize the relationship between experience obtained by different experimental arrangements and visualized only by mutually exclusive ideas, we may truly say that different human cultures are complimentary to each other ... each such culture represents a harmonious balance of traditional conventions by means of which latent potentialities of human life unfold themselves in a way which reveals to us new aspects of its unlimited richness and variety. ~ Niels Bohr

[About the great synthesis of atomic physics in the 1920s]
It was a heroic time. It was not the doing of any one man; it involved the collaboration of scores of scientists from many different lands. But from the first to last the deeply creative, subtle and critical spirit of Niels Bohr guided, restrained, deepened and finally transmuted the enterprise. ~ J. Robert Oppenheimer

The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest lawsof atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience. ~ Willard Van Orman Quine

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

It is remarkable that mind enters into our awareness of nature on two separate levels. At the highest level, the level of human consciousness, our minds are somehow directly aware of the complicated flow of electrical and chemical patterns in our brains. At the lowest level, the level of single atoms and electrons, the mind of an observer is again involved in the description of events. Between lies the level of molecular biology, where mechanical models are adequate and mind appears to be irrelevant. But I, as a physicist, cannot help suspecting that there is a logical connection between the two ways in which mind appears in my universe. I cannot help thinking that our awareness of our own brains has something to do with the process which we call "observation" in atomic physics. That is to say, I think our consciousness is not just a passive epiphenomenon carried along by the chemical events in our brains, but is an active agent forcing the molecular complexes to make choices between one quantum state and another. In other words, mind is already inherent in every electron, and the processes of human consciousness differ only in degree but not in kind from the processes of choice between quantum states which we call "chance" when they are made by electrons. ~ Freeman Dyson

[Regarding mathematics,] there are now few studies more generally recognized, for good reasons or bad, as profitable and praiseworthy. This may be true; indeed it is probable, since the sensational triumphs of Einstein, that stellar astronomy and atomic physics are the only sciences which stand higher in popular estimation. ~ G.H. Hardy

What we can imagine as plausible is a narrow band in the middle of a much broader spectrum of what is actually possible. [O]ur eyes are built to cope with a narrow band of electromagnetic frequencies. [W]e can't see the rays outside the narrow light band, but we can do calculations about them, and we can build instruments to detect them. In the same way, we know that the scales of size and time extend in both directions far outside the realm of what we can visualize. Our minds can't cope with the large distances that astronomy deals in or with the small distances that atomic physics deals in, but we can represent those distances in mathematical symbols. Our minds can't imagine a time span as short as a picosecond, but we can do calculations about picoseconds, and we can build computers that can complete calculations within picoseconds. Our minds can't imagine a timespan as long as a million years, let alone the thousands of millions of years that geologists routinely compute. Just as our eyes can see only that narrow band of electromagnetic frequencies that natural selection equipped our ancestors to see, so our brains are built to cope with narrow bands of sizes and times. Presumably there was no need for our ancestors to cope with sizes and times outside the narrow range of everyday practicality, so our brains never evolved the capacity to imagine them. It is probably significant that our own body size of a few feet is roughly in the middle of the range of sizes we can imag ~ Richard Dawkins

Realizing its fundamental importance in understanding spectral lines, in atomic physics and in the theory of how light and electrons interact, quantum electrodynamics, Pauli and Heisenberg were determined to derive it from quantum theory rather than introducing it from the start. They believed that if they could find a version of quantum electrodynamics capable of producing the fine structure constant, it would not contain the infinities that marred their theories. ~ Arthur I. Miller

Ernest Rutherford's 1908 Nobel Prize in Chemistry wasn't given for the nuclear power station - he wouldn't have survived that long - it was given for showing how interesting atomic physics could be. ~ Andre Geim

Some recent work by E. Fermi and L. Szilárd, which has been communicated to me in manuscript, leads me to expect that the element uranium may be turned into a new and important source of energy in the immediate future. Certain aspects of the situation seem to call for watchfulness and, if necessary, quick action on the part of the Administration. ...

This new phenomenon would also lead to the construction of bombs, and it is conceivable - though much less certain - that extremely powerful bombs of a new type may thus be constructed. A single bomb of this type, carried by boat or exploded in a port, might well destroy the whole port altogether with some of the surrounding territory. However, such bombs might well prove to be too heavy for transportation by air. ~ Albert Einstein

Caroline rose. She studied him for a moment before sitting on his knee.
He wasn't quite sure exactly how it happened. If pressed, he would have asked for three or four hundred pages to write a description of the series of impossibly graceful bendings and movements that ended with her perched there with one hand on his shoulder. He didn't understand - and he was sure that it defied physics - how Caroline could be so light on that tiny patch of his legs, and yet so weighty in the way her presence affected him. Her gaze, for instance, probably clocked in at about fifty or sixty tons, to judge from the effect it was having on him.
He never wanted to move. Never, ever, ever. Let the heat death of the universe come along and he'd be quite happy to still have Caroline Hepworth sitting just like that, on his knee, looking at him without speaking. The tiny light of the shaded lantern was irrelevant. He saw everything, as if it were the brightest of middays.
It was so perfect, so hoped for, that Aubrey knew it couldn't last. He glanced around.
'What are you doing?' Caroline asked very, very softly.
'Looking for whoever is going to interrupt us.'
'That's a pessimistic outlook.'
'Wars, especially, have a habit of ignoring the lives of people.'
'If you follow that through, it suggests living for the moment is best.'
'Live without planning? Without dreams? That sounds rather limited.'
'And that sounds rather like Aubrey. ~ Michael Pryor

There is no morality in the mushroom cloud. The black rain of nuclear ashes will fall alike on the just and the unjust. And then it will be too late to wish that we had done the real work of this atomic age, which is to seek a world that is neither red nor dead. ~ Edward Kennedy

Since the advent of the atomic bomb, the United States has always needed two kinds of enemies. On one level, it has needed a tactical enemy that it can go out and fight in the field in a shooting war. Since 1945, these enemies have been created and appeared as North Korea, North Vietnam, Grenada, El Salvador, Panama, Iraq and now Colombia. On another level, however, the US needs a strategic enemy that will justify outrageous expenditures of capital for strategic weapon systems like ICBMs, Trident submarines and "Star Wars" missile defence systems. ~ Michael Ruppert

[In high school] my interests outside my academic work were debating, tennis, and to a lesser extent, acting. I became intensely interested in astronomy and devoured the popular works of astronomers such as Sir Arthur Eddington and Sir James Jeans, from which I learnt that a knowledge of mathematics and physics was essential to the pursuit of astronomy. This increased my fondness for those subjects. ~ Allan McLeod Cormack

The total number of people who understand relativistic time, even after eighty years since the advent of special relativity, is still much smaller than the number of people who believe in horoscopes. ~ Yuval Ne'eman

His laws changed all of physics and astronomy. His laws made it possible to calculate the mass of the sun and planets. The way it's done is immensely beautiful. If you know the orbital period of any planet, say, Jupiter or the Earth and you know its distance to the Sun; you can calculate the mass of the Sun. Doesn't this sound like magic?

We can carry this one step further - if you know the orbital period of one of Jupiter's bright moons, discovered by Galileo in 1609, and you know the distance between Jupiter and that moon, you can calculate the mass of Jupiter. Therefore, if you know the orbital period of the moon around the Earth (it's 27.32 days), and you know the mean distance between the Earth and the moon (it's about 200,039 miles), then you can calculate to a high degree of accuracy the mass of the Earth.

… But Newton's laws reach far beyond our solar system. They dictate and explain the motion of stars, binary stars, star clusters, galaxies and even clusters of galaxies. And Newton's laws deserve credit for the 20th century discovery of what we call dark matter.

His laws are beautiful. Breathtakingly simple and incredibly powerful at the same time. They explain so much and the range of phenomena they clarify is mind boggling. By bringing together the physics of motion, of interaction between objects and of planetary movements, Newton brought a new kind of order to astronomical measurements, showing how, what had been a jumble of con ~ Walter Lewin

They told me that, as a woman, I'd never get into graduate school in physics, so they got me a job as a secretary at the College of Physicians and Surgeons and promised that, if I were a good girl, I would take courses there. ~ Rosalyn Sussman Yalow

The Heart of Gold fled on silently through the night of space, now on conventional photon drive. Its crew of four were ill as ease knowing that they had been brought together not of their own volition or by simple coincidence, but by some curious perversion of physics- as if relationships between people were susceptible to the same laws that governed the relationships between atoms and molecules ~ Douglas Adams

Even a good, inveterate atheist like physicist Richard Feynman once said of the fine structure constant, "All good theoretical physicists put this number up on their wall and worry about it…. It's one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man. You might say the 'hand of God' wrote that number, and we don't know how He pushed His pencil. ~ Sam Kean

There is beauty in space, and it is orderly. There is no weather, and there is regularity. It is predictable. Just look at our little Explorer; you can set your clock by it-literally; it is more accurate than your clock. Everything in space obeys the laws of physics. If you know these laws, and obey them, space will treat you kindly. ~ Wernher Von Braun

Pragmatism , in trying to turn experimental physics into a prototype of all science and to model all spheres of intellectual life after the techniques of the laboratory, is the counterpart of modern industrialism, for which the factory is the prototype of human existence, and which models all branches of culture after production on the conveyor belt. ~ Max Horkheimer

The next grand extensions of mathematical physics will, in all likelihood, be furnished by quaternions. ~ Peter Tait

The advantage of a quantum walk over a classical random walk can be appreciated by returning to our slow-moving drunk and imagining that the bar he leaves has sprung a leak and that water is pouring out of its door. ~ Jim Al-Khalili

I suppose my interest in looking for life elsewhere in the universe really dates back to my teens. What teenager doesn't look up at the sky at night and think am I alone in the universe? Well most people get over it, but I never did and though I made a career more in physics and cosmology than astrobiology I've always had a soft spot for the subject of life because it does seem so mysterious. ~ Paul Davies

In the world of the very small, where particle and wave aspects of reality are equally significant, things do not behave in any way that we can understand from our experience of the everyday world ... all pictures are false, and there is no physical analogy we can make to understand what goes on inside atoms. Atoms behave like atoms, nothing else. ~ John Gribbin

While at Chicago my interest in the new field of particle physics was stimulated by a course given by Gell- Mann, who was developing his ideas about Strangeness at the time. ~ James Cronin

No, no, no, no physics over breakfast! ~ Karen Marie Moning

Man's awesome scientific advances into the infinitude of space as well as the infinitude of sub-atomic particles seems most likely to lead to the total destruction of our world unless we can make great advances in understanding and dealing with interpersonal and inter-group tensions. I ~ Carl R. Rogers

Physics is the belief that a simple and consistent description of nature is possible. ~ Niels Bohr

The existence of matter and energy in the universe did not require the violation of energy conservation at the assumed creation. In fact, the data strongly support the hypothesis that no such miracle occurred. If we regard such a miracle as predicted by the creator hypothesis, then the prediction is not confirmed. ~ Victor J. Stenger

To be honest, what I struggled with in my degree is what's so helpful when it comes to social media in that I lack focus. I'll start reading about evolutionary biology and end up on quantum physics. While that makes writing your dissertation very difficult, for a page like IFLS, that's amazing because I get a wide range of everything. ~ Elise Andrew

Basically, I wasn't properly socialized, so it made sense to do physics. ~ Lisa Randall

So the bottom line is that if you believe in an external reality independent of humans, then you must also believe that our physical reality is a mathematical structure. Nothing else has a baggage-free description. In other words, we all live in a gigantic mathematical object-one that's more elaborate than a dodecahedron, and probably also more complex than objects with intimidating names such as Calabi-Yau manifolds, tensor bundles and Hilbert spaces, which appear in today's most advanced physics theories. Everything in our world is purely mathematical-including you. ~ Max Tegmark

Failed a physics test," Nick said.
"You know how I solve that problem?" Said his twin. "I don't take physics. ~ Brigid Kemmerer

On Gortician, a promotion was survival. Firings were literal. You were incinerated, and your successor's first job was sweeping your ashes up for Ned's Atomic
Dustbin, Gortician's recycle center. ~ Jason Z. Christie

You might ask why we cannot teach physics by just giving the basic laws on page one and then showing how they work in all possible circumstances, as we do in Euclidean geometry, where we state the axioms and then make all sorts of deductions. (So, ~ Richard Feynman

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 German physicists knew at least so much about the manufacture and construction of atomic bombs that it was clear to them that the manufacture of bombs in Germany could not succeed during the war. For this reason, they were spared the moral decision whether they should make an atomic bomb, and they had only worked on the uranium engine. ~ Werner Heisenberg

The basic science is not physics or mathematics but biology
the study of life. We must learn to think both logically and bio-logically. ~ Edward Abbey

Trying to get a read on Apple Computer is a lot like learning about quantum physics; you can never know Apple's position on a technology, and its direction, simultaneously. ~ Mark Pesce

Some people find importance in the photographs of those titanic mushrooms of atomic poison which are periodically exploded over the world's deserts; I find greater importance in one very small mushroom which mysteriously springs up in the shadow of the tool-shed. ~ Beverley Nichols

All the rare-book dealers regaled me with stories of the trade. They told me that after the war there were too many books and not enough bookshop space, so all the dealers in London BURIED hundreds of old books in the open bomb craters of London streets. Today the buried books would be worth a fortune if they could be recovered, if the new buildings could be torn down and the rebuilt streets torn up. I had a sudden vision of an atomic war destroying everything in the world, except here and there an old book lying where it fell when it was blasted up out of the depths of London. ~ Helene Hanff

Physics does not change the nature of the world it studies, and no science of behavior can change the essential nature of man, even though both sciences yield technologies with a vast power to manipulate the subject matters. ~ Pope Paul VI

Neutrinos, they are very small.
They have no charge and have no mass
And do not interact at all.
The earth is just a silly ball
To them, through which they simply pass,
Like dustmaids down a drafty hall
Or photons through a sheet of glass.
They snub the most exquisite gas,
Ignore the most substantial wall,
Cold shoulder steel and sounding brass,
Insult the stallion in his stall,
And, scorning barriers of class,
Infiltrate you and me. Like tall
And painless guillotines they fall
Down through our heads into the grass.
At night, they enter at Nepal
And pierce the lover and his lass
From underneath the bed - you call
It wonderful; I call it crass. ~ John Updike

Anybody who has done high school physics knows Newton's Third Law. For every action there is an equal and opposite reaction. You push against a wall; it pushes back against you. I love the poetry hidden in these truths, in the many laws we've discovered that underpin the universal fabric. We search for meaning ever hungrier, perhaps even with desperation: the symmetry in the equations freaks us out; for all we know, there is just us on this lonely little marble in the inky void. ~ Sean J Halford

The realization that time can behave like another direction of space means one can get rid of the problem of time having a beginning, in a similar way in which we got rid of the edge of the world.

Suppose the beginning of the universe was like the South Pole of the earth, with degrees of latitude playing the role of time.

As one moves north, the circles of constant latitude, representing the size of the universe, would expand. The universe would start as a point at the South Pole, but the South Pole is much like any other point.

To ask what happened before the beginning of the universe would become a meaningless question, because there is nothing south of the South Pole. ~ Stephen Hawking

There was no room for dust devils in the laws of physics, as least in the rigid form in which they were usually taught. There is a kind of unspoken collusion going on in mainstream science education: you get your competent but bored, insecure and hence stodgy teacher talking to an audience divided between engineering students, who are going to be responsible for making bridges that won't fall down or airplanes that won't suddenly plunge vertically into the ground at six hundred miles an hour, and who by definition get sweaty palms and vindictive attitudes when their teacher suddenly veers off track and begins raving about wild and completely nonintuitive phenomena; and physics students, who derive much of their self-esteem from knowing that they are smarter and morally purer than the engineering students, and who by definition don't want to hear about anything that makes no fucking sense. This collusion results in the professor saying: (something along the lines of) dust is heavier than air, therefore it falls until it hits the ground. That's all there is to know about dust. The engineers love it because they like their issues dead and crucified like butterflies under glass. The physicists love it because they want to think they understand everything. No one asks difficult questions. And outside the windows, the dust devils continue to gambol across the campus. ~ Neal Stephenson

An integral approach is based on one basic idea: no human mind can be 100% wrong. Or, we might say, nobody is smart enough to be wrong all the time. And that means, when it comes to deciding which approaches, methodologies, epistemologies, or ways or knowing are "correct," the answer can only be, "All of them." That is, all of the numerous practices or paradigms of human inquiry - including physics, chemistry, hermeneutics, collaborative inquiry, meditation, neuroscience, vision quest, phenomenology, structuralism, subtle energy research, systems theory, shamanic voyaging, chaos theory, developmental psychology - all of those modes of inquiry have an important piece of the overall puzzle of a total existence that includes, among other many things, health and illness, doctors and patients, sickness and healing. ~ Ken Wilber

I never studied science or physics at school, and yet when I read complex books on quantum physics I understood them perfectly because I wanted to understand them. The study of quantum physics helped me to have a deeper understanding of the Secret, on an energetic level, ~ Rhonda Byrne

So we're damned if we do and damned if we don't." She shrugged. "That pretty much sums up quantum physics. ~ James Rollins

Nothing can be rightly known, if God be not known; nor is any study well managed, nor to any great purpose, if God is not studied. We know little of the creature, till we know it as it stands related to the Creator: single letters, and syllables uncomposed, are no better than nonsense. He who overlooketh him who is the 'Alpha and Omega, the beginning and the ending,' and seeth not him in all who is the All of all, doth see nothing at all. All creatures, as such, are broken syllables; they signify nothing as separated from God. Were they separated actually, they would cease to be, and the separation would be annhiliation; and when we separate them in our fancies, we make nothing of them to ourselves. It is one thing to know the creatures as Aristotle, and another thing to know them as a Christian. None but a Christian can read one line of his Physics so as to understand it rightly. It is a high and excellent study, and of greater use than many apprehend; but it is the smallest part of it that Aristotle can teach us. ~ Richard Baxter

The ray of light has to know where it will ultimately end up before it can choose the direction to begin moving in"

"Fermat's principle sounds weird because it describes light's behavior in goal-oriented terms. It sounds like a commandment to a light beam: "Thou shalt minimize or maximize the time taken to reach thy destination. ~ Ted Chiang

You don't get rich from doing physics, but you do get an opportunity to go to all the places the rich would go to if they had the time. ~ Per Bak

Prototypes of inventions that use novel combinations of resonance, magnetism, states of matter, certain geometries or inward swirling motion to unlock the secrets of universal energy have already been built. They provide proof of new or rediscovered principles. In many variations of these inventions, a small input triggers a disproportionately large output of useable power."
"These energy converters don't violate any laws of physics if they simply tap into a previously unrecognized source of power - background space. A flow of energy from that source can continue day and night, whether or not the sun shines or the wind blows. ~ Jeane Manning

General Atomics, the progenitor of General Atomics Aeronautical Systems, started life in 1955 when a major military contractor, General Dynamics, feared that the military hardware market might dry up. It began exploring peacetime uses of atomic energy, but abandoned the effort when cold-war military spending took off. ~ Charles Duhigg

Physics, my friend, is a narrow path drawn across a gulf that the human imagination cannot grasp. It is a set of answers to certain questions that we put to the world, and the world supplies the answers on the condition that we will not then ask it other questions, questions shouted out by common sense. And common sense? It is that which is understood by an intelligence using senses no different from those of a baboon. Such an intelligence wishes to know the world in terms that apply to its terrestrial, biological niche. But the world - outside that niche, that incubator of sapient apes - has properties that one cannot take in hand, see, sniff, gnaw, listen to, and in this way appropriate. ~ Stanislaw Lem
