Nature has a great simplicity and therefore a great beauty
Richard Feynman
Despite my resistance to hyperbole, the LHC belongs to a world that can only be described with superlatives. It is not merely large: the LHC is the biggest machine ever built. It is not merely cold: the 1.9 kelvin (1.9 degrees Celsius above absolute zero) temperature necessary for the LHC’s supercomputing magnets to operate is the coldest extended region that we know of in the universe—even colder than outer space. The magnetic field is not merely big: the superconducting dipole magnets generating a magnetic field more than 100,000 times stronger than the Earth’s are the strongest magnets in industrial production ever made.And the extremes don’t end there. The vacuum inside the proton-containing tubes, a 10 trillionth of an atmosphere, is the most complete vacuum over the largest region ever produced. The energy of the collisions are the highest ever generated on Earth, allowing us to study the interactions that occurred in the early universe the furthest back in time.
Lisa Randall
There was a young lady named Bright,Whose speed was far faster than light;She started one dayIn a relative way,And returned on the previous night.
Arthur Henry Reginald Buller
My idea of an educated person is one who can converse on one subject for more than two minutes.
Robert Andrews Millikan
If instead of arranging the atoms in some definite pattern, again and again repeated, on and on, or even forming little lumps of complexity like the odor of violets, we make an arrangement which is always different from place to place, with different kinds of atoms arranged in many ways, continually changing, not repeating, how much more marvelously is it possible that this thing might behave? Is it possible that that "thing" walking back and forth in front of you, talking to you, is a great glob of these atoms in a very complex arrangement, such that the sheer complexity of it staggers the imagination as to what it can do? When we say we are a pile of atoms, we do not mean we are merely a pile of atoms, because a pile of atoms which is not repeated from one to the other might well have the possibilities which you see before you in the mirror.
Richard Feynman
As to your Newton, I confess I do not understand his void and his gravity; I admit he has demonstrated the movement of the heavenly bodies with more exactitude than his forerunners; but you will admit it is an absurdity to maintain the existence of No
Frederick the Great
Yet if there really were a complete unified theory, it would also presumably determine our actions—so the theory itself would determine the outcome of our search for it! And why should it determine that we come to the right conclusions from the evidence? Might it not equally well determine that we draw the wrong conclusion? Or no conclusion at all?
Stephen Hawking
Is numerical equality (forced by the use of specific physical units) the same as conceptual equality? Of course NOT!
Felix Alba-Juez
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
It is worth noting that a wrong folkoric definition of an Inertial Frame in the Popular Science literature (even in text books) reads that 'it is a frame in uniform motion'. We know very well by now that the idea of motion requires a frame of reference, so that such a definition of an Inertial Frame has no meaning whatsoever, confusing the reader because it tacitly reaffirms the idea of absolute motion -- when the goal of every didactic exposition of Relativity Theory should be precisely the opposite.
Felix Alba-Juez
While Newton seemed to draw off the veil from some of the mysteries of nature, he showed at the same time the imperfections of the mechanical philosophy, so agreeable to the natural vanity and curiosity of men; and thereby restored her ultimate secrets to that obscurity, in which they ever did and ever will remain.
David Hume
Individual events. Events beyond law. Events so numerous and so uncoordinated that, flaunting their freedom from formula, they yet fabricate firm form.
John Archibald Wheeler
And as they drifter up their minds sang with the ecstatic knowledge that either what they were doing was completely and utterly and totally impossible or that physics had a lot of catching up to do.Physics shook its head and, looking the other way, concentrated on keeping the cards going along the Euston Road and out over towards the Westway flyover, on keeping the street lights lit and on making sure that when somebody on Baker Street dropped a cheeseburger it went splat on the ground.
Douglas Adams
As for karma itself, it is apparently only that which binds "jiva" (sentience, life, spirit, etc.) with "ajiva" (the lifeless, material aspect of this world) - perhaps not unlike that which science seeks to bind energy with mass (if I understand either concept correctly). But it is only through asceticism that one might shed his predestined karmic allotment.I suppose this is what I still don't quite understand in any of these shramanic philosophies, though - their end-game. Their "moksha", or "mukti", or "samsara". This oneness/emptiness, liberation/ transcendence of karma/ajiva, of rebirth and ego - of "the self", of life, of everything. How exactly would this state differ from any standard, scientific definition of death? Plain old death. Or, at most, if any experience remains, from what might be more commonly imagined/feared to be death - some dark perpetual existence of paralyzed, semi-conscious nothingness. An incessant dreamless sleep from which one never wakes? They all assure you, of course, that this will be no condition of endless torment, but rather one of "eternal bliss". Inexplicable, incommunicable "bliss", mind you, but "bliss" nonetheless. So many in the realm of science, too, seem to propagate a notion of "bliss" - only here, in this world, with the universe being some great amusement park of non-stop "wonder" and "discovery". Any truly scientific, unbiased examination of their "discoveries", though, only ever seems to reveal a world that simply just "is" - where "wonder" is merely a euphemism for ignorance, and learning is its own reward because, frankly, nothing else ever could be. Still, the scientist seeks to conquer this ignorance, even though his very happiness depends on it - offering only some pale vision of eternal dumbfoundedness, and endless hollow surprises. The shramana, on the other hand, offers total knowledge of this hollowness, all at once - renouncing any form of happiness or pleasure, here, to seek some other ultimate, unknowable "bliss", off in the beyond...
Mark X.
I studied calculus for the first time, which to me was an amazingly empowering experience which I could really see how you could understand all sorts of things, and I decided that chemistry and biology just had too much memory for me to be interested. Physics was very easy.
Marshall Nicholas Rosenbluth
Cecile was teaching in Berkeley and I was [at Livermore]. He probably had, could have had, some influence on Teller, [for] Teller was quite generous in allowing me one whole semester off to be at Berkeley to work on something and also a semester off at the Institute for Advanced Study. Then I won the Gravity Research Foundation first prize.
Bryce S. DeWitt
I like physics, but I love cartoons.
Stephen Hawking
We all love a good story. We all love a tantalizing mystery. We all love the underdog pressing onward against seemingly insurmountable odds. We all, in one form or another, are trying to make sense of the world around us. And all of these elements lie at the core of modern physics. The story is among the grandest -- the unfolding of the entire universe; the mystery is among the toughest -- finding out how the cosmos came to be; the odds are among the most daunting -- bipeds, newly arrived by cosmic time scales trying to reveal the secrets of the ages; and the quest is among the deepest -- the search for fundamental laws to explain all we see and beyond, from the tiniest particles to the most distant galaxies.
Brian Greene
A physicist, an engineer and a psychologist are called in as consultants to a dairy farm whose production has been below par. Each is given time to inspect the details of the operation before making a report.The first to be called is the engineer, who states: "The size of the stalls for the cattle should be decreased. Efficiency could be improved if the cows were more closely packed, with a net allotment of 275 cubic feet per cow. Also, the diameter of the milking tubes should be increased by 4 percent to allow for a greater average flow rate during the milking periods."The next to report is the psychologist, who proposes:"The inside of the barn should be painted green. This is a more mellow color than brown and should help induce greater milk flow. Also, more trees should be planted in the fields to add diversity to the scenery for the cattle during grazing, to reduce boredom."Finally, the physicist is called upon. He asks for a blackboard and then draws a circle. He begins: "Assume the cow is a sphere....
Lawrence M. Krauss
(On the energy radiated by the Sun)It's four hundred million million million million watts. That is a million times the power consumption of the United States every year, radiated in one second, and we worked that out by using some water, a thermometer, a tin, and an umbrella. And that's why I love physics.
Brian Cox
Until now, I've been writing about "now" as if it were literally an instant of time, but of course human faculties are not infinitely precise. It is simplistic to suppose that physical events and mental events march along exactly in step, with the stream of "actual moments" in the outside world and the stream of conscious awareness of them perfectly synchronized. The cinema industry depends on the phenomenon that what seems to us a movie is really a succession of still pictures, running at twenty-five [sic] frames per second. We don't notice the joins. Evidently the "now" of our conscious awareness stretches over at least 1/25 of a second.In fact, psychologists are convinced it can last a lot longer than that. Take he familiar "tick-tock" of the clock. Well, the clock doesn't go "tick-tock" at all; it goes "tick-tick," every tick producing the same sound. It's just that our consciousness runs two successive ticks into a singe "tick-tock" experience—but only if the duration between ticks is less than about three seconds. A really bug pendulum clock just goes "tock . . . tock . . . tock," whereas a bedside clock chatters away: "ticktockticktock..." Two to three seconds seems to be the duration over which our minds integrate sense data into a unitary experience, a fact reflected in the structure of human music and poetry.
Paul Davies
In the beginning, there was physics. "Physics" describes how matter, energy, space, and time behave and interact with one another. The interplay of these characters in our cosmic drama underlies all biological and chemical phenomena. Hence everything fundamental and familiar to us earthlings begins with, and rests upon, the laws of physics. When we apply these laws to astronomical settings, we deal with physics writ large, which we call astrophysics.
Neil deGrasse Tyson
Programmed by quanta, physics gave rise first to chemistry and then to life; programmed by mutations and recombination, life gave rise to Shakespeare; programmed by experience and imagination, Shakespeare gave rise to Hamlet.
Seth Lloyd
THE QUESTION IS, OF COURSE, IS IT GOING TO BE POSSIBLE TO AMALGAMATE EVERYTHING,AND MERELY DISCOVER THAT THIS WORLD REPRESENTS DIFFERENT ASPECTS OF ONE THING?
Richard Feynman
CURIOSITY DEMANDS THAT WE ASK QUESTIONS,THAT WE TRY TO PUT THINGS TOGETHER AND TRY TO UNDERSTAND THIS MULTITUDE OF ASPECTSAS PERHAPS RESULTING FROM THE ACTION OF A RELATIVELY SMALL NUMBER OF ELEMENTALTHINGS AND FORCES ACTING IN AN INFINITE VARIETY OF COMBINATIONS
Richard Feynman
Physics admits of a lovely unification, not just at the level of fundamental forces, but when considering its extent and implications. Classifications like "optics" or "thermodynamics" are just straitjackets, preventing physicists from seeing countless intersections.
Ted Chiang
Perhaps there are many "nows" of varying duration, depending on just what it is we are doing. We must face up to the fact that, at least in the case of humans, the subject experiencing subjective time is not a perfect, structureless observer, but a complex, multilayered, multifaceted psyche. Different levels of our consciousness may experience time in quite different ways. This is evidently the case in terms of response time. You have probably had the slightly unnerving experience of jumping at the sound of a telephone a moment or two before you actually hear it ring. The shrill noise induces a reflex response through the nervous system much faster than the time it takes to create the conscious experience of the sound.It is fashionable to attribute certain qualities, such as speech ability, to the left side of the brain, whereas others, such as musical appreciation, belong to processes occurring on the right side. But why should both hemispheres experience a common time? And why should the subconscious use the same mental clock as the conscious?
Paul Davies
No non-poetic account of reality can be complete.
John Myhill
We have sought for firm ground and found none. The deeper we penetrate, the more restless becomes the universe; all is rushing about and vibrating in a wild dance.
Max Born
Radar is too long in the tooth for fine detail.
Peter Watts
In some sense, gravity does not exist; what moves the planets and the stars is the distortion of space and time.
Michio Kaku
After that cancellation [of the Superconducting Super Collider in Texas, after $2 billion had been spent on it], we physicists learned that we have to sing for our supper. ... The Cold War is over. You can't simply say “Russia!” to Congress, and they whip out their checkbook and say, “How much?” We have to tell the people why this atom-smasher is going to benefit their lives.
Michio Kaku
If antimatter and matter make contact, both are destroyedinstantly. Physicists call the process ‘annihilation.
Dan Brown
The great object is to find the theory of the matter [of X-rays] before anyone else, for nearly every professor in Europe is now on the warpath.
Ernest Rutherford
After the discovery of spectral analysis no one trained in physics could doubt the problem of the atom would be solved when physicists had learned to understand the language of spectra. So manifold was the enormous amount of material that has been accumulated in sixty years of spectroscopic research that it seemed at first beyond the possibility of disentanglement. An almost greater enlightenment has resulted from the seven years of Röntgen spectroscopy, inasmuch as it has attacked the problem of the atom at its very root, and illuminates the interior. What we are nowadays hearing of the language of spectra is a true 'music of the spheres' in order and harmony that becomes ever more perfect in spite of the manifold variety. The theory of spectral lines will bear the name of Bohr for all time. But yet another name will be permanently associated with it, that of Planck. All integral laws of spectral lines and of atomic theory spring originally from the quantum theory. It is the mysterious organon on which Nature plays her music of the spectra, and according to the rhythm of which she regulates the structure of the atoms and nuclei.
Arnold Sommerfeld
There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.
William Thomson
The standard cosmological theory--an expanding universe--does not really solve the problem of God. It simply makes it more problematical. Once the creator-creation model is discarded as primitive mythology, we still have not touched the ancient conundrum, ex nihilo nihil fit: nothing comes from nothing, and the "axiom" that "Nothing is unstable' rivals in scholastic absurdity anything Aquinas may have said eight hundred years ago and can only be postulated given the reality of something, whereby it becomes a self-evident and unarguable tautology.
R. Joseph Hoffmann
Surely, the gods' judgment is certain. But as for us, we must be satisfied to 'come close' to those things, for we are men, who speak according to what is likely, and whose lectures resemble fables.
Proclus
The history of atomism is one of reductionism – the effort to reduce all the operations of nature to a small number of laws governing a small number of primordial objects.
Leon M. Lederman
Einstein's paper on the photoelectric effect was the work for which he ultimately won the Nobel Prize. It was published in 1905, and Einstein has another paper in the very same journal where it appeared - his other paper was the one that formulated the special theory of relativity. That's what it was like to be Einstein in 1905; you publish a groundbreaking paper that helps lay the foundation of quantum mechanics, and for which you later win the Nobel Prize, but it's only the second most important paper that you publish in that issue of the journal.
Sean Carroll
[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
Nature is not embarrassed by difficulties of analysis. She avoids complication only in means. Nature seems to be proposed to do much with little: it is a principle that the development of physics constantly supports by new evidence.
Jean Fresnel
There was yet another disadvantage attaching to the whole of Newton’s physical inquiries, ... the want of an appropriate notation for expressing the conditions of a dynamical problem, and the general principles by which its solution must be obtained. By the labours of LaGrange, the motions of a disturbed planet are reduced with all their complication and variety to a purely mathematical question. It then ceases to be a physical problem; the disturbed and disturbing planet are alike vanished: the ideas of time and force are at an end; the very elements of the orbit have disappeared, or only exist as arbitrary characters in a mathematical formula.
George Boole
In fact, meta- and particle physicists have more in common than one might suppose: both tug, if in slightly different directions, at the knots which hold the cosmos together, both look beyond the immediate world of sense perception into one where cause can only be deduced from effect - a quark is as invisible as an angel; both are confronted by Manichaean polarities - miracles and black magic, cheap energy versus total destruction.
Tim Mackintosh-Smith
In the last four days I have got the (results) given by Tantalum, Chromium, Manganese, Iron , Nickel, Cobalt and Copper ... The chief result is that ... the result for any metal (is) quite easy to guess from the results for the others. This shews that the insides of all the atoms are very much alike, and from these results it will be possible to find out something of what the insides are made up of.
Henry Moseley
It must have appeared almost as improbable to the earlier geologists, that the laws of earthquakes should one day throw light on the origin of mountains, as it must to the first astronomers, that the fall of an apple should assist in explaining the motions of the moon.
Charles Lyell
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
If a problem is clearly stated, it has no further interest to the physicist.
Peter Debye
The human mind is woven into the energy fabric of the universe.John A. Wheeler
Katherine Ramsland
PHYSICS to me.. umm well it's like ENERGY, spreading in all DIMENSION of mind which tends to the TENSION, which FORCES the MOTION to come out.
A.Z. black
Since the beginning of physics, symmetry considerations have provided us with an extremely powerful and useful tool in our effort to understand nature. Gradually they have become the backbone of our theoretical formulation of physical laws.
Tsung-Dao Lee
Physics is the ultimate intellectual adventure, the quest to understand the deepest mysteries of our Universe. Physics doesn’t take something fascinating and make it boring. Rather, it helps us see more clearly, adding to the beauty and wonder of the world around us.
Max Tegmark
Anyone who can relax, clear their mind, and envision being different in some way—such as more successful, funny, healthy, wealthy, or wise—can quantum jump. To initiate a quantum jump requires keeping an open mind that you can experience another reality. It is important that you are able to sincerely desire and feel a connection to another reality, envisioning some way of making a connection with it through a bridge, a door, a window or a handshake.
Cynthia Sue Larson
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 Körner
A mathematician may say anything he pleases, but a physicist must be at least partially sane.
J.Williard Gibbs
Planck...and Bohr...have invented systems containing electrons of which the motion produces no effect upon external charges...[N]ot only [is this] inconsistent with the accepted laws of electromagnetism, but I may add, is logically objectionable, for that state of motion which produces no physical effect whatsoever may better be called a state of rest.
G.N.Lewis
All integral laws of spectral lines and of atomic theory spring originally from the quantum theory. It is the mysterious organon on which Nature plays her music of the spectra, and according to the rhythm of which she regulates the structure of the atoms and nuclei.
Arnold Sommerfeld
Physicists love this number not just because it is dimensionless, but also because it is a combination of three fundamental constants of nature. Why do these constants come together to make the particular number 1/137.036 and not some other number?
John Archibald Wheeler
For [Wolfgang] Pauli the central problem of electrodynamics was the field concept and the existence of an elementary charge which is expressible by the fine-structure constant ... 1/137. This fundamental pure number had greatly fascinated Pauli, .... For Pauli the explanation of the number 137 was the test of a successful field theory, a test which no theory has passed up to now.
Charles P. Enz
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.
