Arthur Compton became my graduate advisor. He was the ideal graduate advisor for me: he came into my research room only once during my graduate career and usually had no idea how I was spending my time.
Luis W. Alvarez
Robert Oppenheimer used to tell of the pioneer mysteries of building reliable Geiger counters that had low background noise. Among his friends, he said, there were two schools of thought. One school firmly held that the final step before one sealed off the Geiger tube was to peel a banana and wave the skin three times, sharply to the left.The other school was equally confident that success would follow if one waved the banana peel twice to the left and then, once, smartly to the right. (My counters were unbelievably bad because I didn't use either of these techniques.)
Luis W. Alvarez
Dirac's equation not only accounted for the spin of the electron and its observed magnetic moment, but also correctly explained the fine structure of the hydrogen atom. If the derivation of the Sommerfeld-like formula for the spectrum of the hydrogen atom was one of the striking successes of the Dirac equation, some of its other features were very troublesome.
Silvan S. Schweber
God is a pure mathematician!' declared British astronomer Sir James Jeans. The physical Universe does seem to be organised around elegant mathematical relationships. And one number above all others has exercised an enduring fascination for physicists: 137.0359991.... It is known as the fine-structure constant and is denoted by the Greek letter alpha (α).
Paul Davies
Joe’s scientific life is defined by these significant near misses… He was Shackleton many times, almost the first: almost the first to see the big bang, almost the first to patent the laser, almost the first to detect gravitational waves. Famous for nearly getting there.
Janna Levin
What are we, in this boundless and glowing world?
Carlo Rovelli
It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy - or in our physics.
Carlo Rovelli
A university student attending lectures on general relativity i the morning and others on quantum mechanics in the afternoon might be forgiven for thinking that his professors are fools, or have neglected to communicate with each other for at least a century.
Carlo Rovelli
There should be no boundary to human endeavor.
Stephen Hawking
Infinity...is used in physics simply as a shorthand for "a very big number.
Victor J. Stenger
Way back in 1831, Michael Faraday, one of the founders of our modern understanding of electromagnetism, was asked by an inquiring politician about the usefulness of this newfangled "electricity" stuff. His apocryphal reply: "I know not, but I wager that one day your government will tax it".
Sean Carroll
The bridge between the electron and the other elementary particles is provided by the fine structure constant. ... An expanded form of the constant leads to equations that define the transformation of electromagnetic energy into electron mass/energy, ...
Malcolm H. Mac Gregor
In his first philosophical lecture on modern physics that Pauli gave in November 1934 to the Zurich Philosophical Society he said that only a formulation of quantum theory would be satisfactory which expresses the relation between the value of [the fine structure constant] and charge conservation in the same complementary was as that between the space-time description and energy-momentum conservation.
Charles P. Enz
The next question was — what makes planets go around the sun? At the time of Kepler some people answered this problem by saying that there were angels behind them beating their wings and pushing the planets around an orbit. As you will see, the answer is not very far from the truth. The only difference is that the angels sit in a different direction and their wings push inward.
Richard Feynman
An idea sparked in the 1960s, a thought experiment, an amusing haiku, is now a thing of metal and glass.
Janna Levin
Quite obviously, a theoretical determination of the numerical value of α would signify great progress in our understanding of fundamental interactions. Many physicists have tried to find it, but without significant success to this day. Richard Feynman, the theory wizard of Caltech in Pasadena, once suggested that every one of his theory colleagues should write on the blackboard in his office: 137 -- how shamefully little we understand!
Harald Fritzsch
Calculate the fine structure constant from first principles.
David J. Griffiths
Here the attention of the research workers is primarily directed to the problem of reconciling the claims of the special relativity theory with those of the quantum theory. The extraordinary advances made in this field by Dirac ... leave open the question whether it will be possible to satisfy the claims of the two theories without at the same time determining the Sommerfeld fine-structure constant.
Werner Heisenberg
We can measure the fine structure constant with very great precision, but so far none of our theories has provided an explanation of its measured value. One of the aims of superstring theory is to predict this quantity precisely. Any theory that could do that would be taken very seriously indeed as a potential 'Theory of Everything'.
John D. Barrow
... it should be remembered that the atomicity of electric charge has already found its expression in the specific numerical value of the fine structure constant, a theoretical understanding of which is still missing today.
Wolfgang Pauli
The laws of physics could be like an onion, with new laws becoming operational as we probe new scales. We simply don't know!
Richard Feynman
We present a series of hypotheses and speculations, leading inescapably to the conclusion that SU(5) is the gauge group of the world — that all elementary particle forces (strong, weak, and electromagnetic) are different manifestations of the same fundamental interaction involving a single coupling strength, the fine-structure constant. Our hypotheses may be wrong and our speculations idle, but the uniqueness and simplicity of our scheme are reasons enough that it be taken seriously.
Howard Georgi & S. L. Glashow
True, the Standard Model does explain a very great deal. Nevertheless it is not yet a proper theory, principally because it does not satisfy the physicists naive faith in elegance and simplicity. It involves some 17 allegedly fundamental particles and the same number of arbitrary and tunable parameters, such as the fine-structure constants, the muon-electron mass ratio and the various mysterious mixing angles.
Sheldon L. Glashow
To calculate 'the' fine structure constant, 1/137, we would need a realistic model of just about everything, and this we do not have. In this talk I want to return to the old question of what it is that determines gauge couplings in general, and try to prepare the ground for a future realistic calculation.
Steven Weinberg
At one point in the story, following a brazen daytime bank robbery, Electro is shown escaping from the authorities by climbing up the side of a building, as easily as Spider-Man . . . we see one observer exclaim, "Look!! That strangely-garbed man is racing up the side of the building!" A second man on the street picks up the narrative: "He's holding on to the iron beams in the building by means of electric rays—using them like a magnet!! Incredible!"There are three feelings inspired by this scene. The first is wonder as to why people rarely use the phrase "strangely-garbed" anymore. The second is nostalgia for the bygone era when pedestrians would routinely narrate events occurring in front of them, providing exposition for any casual bystander. And the third is pleasure at the realization that Electro's climbing this building is actually a physically plausible use of his powers.
James Kakalios
The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve. We should be grateful for it and hope that it will remain valid in future research and that it will extend, for better or for worse, to our pleasure, even though perhaps also to our bafflement, to wide branches of learning.
Eugene Paul Wigner
It can only be our familiarity with soap bubbles from our earliest recollections, causing us to accept their existence as a matter of course, that prevents most of us from being seriously puzzled as to why they can be blown at all.
C. V. (Charles Vernon) Boys
Wolfgang Pauli, in the months before Heisenberg's paper on matrix mechanics pointed the way to a new quantum theory, wrote to a friend, "At the moment physics is again terribly confused. In any case, it is too difficult for me, and I wish I had been a movie comedian or something of the sort and had never heard of physics." That testimony is particularly impressive if contrasted with Pauli's words less than five months later: "Heisenberg's type of mechanics has again given me hope and joy in life. To be sure it does not supply the solution to the riddle, but I believe it is again possible to march forward.
Wolfgang Pauli
The unsolved problems of the physical world now seem even more formidable than those solved in the twentieth century. Though in application it works splendidly, we do not even understand the physical meaning of quantum mechanics, much less how it might be united with general relativity.We don't know why the dimensionless constants (ratios of masses of elementary particles, ratios of strength of gravitational to electric forces, fine structure constant, etc.) have the values they do, unless we appeal to the implausible anthropic principle, which seems like a regression to Aristotelian teleology.
Gerald Holton
The power of the deductive network produced in physics has been illustrated in a delightful article by Victor F. Weisskopf. He begins by taking the magnitudes of six physical constants known by measurement: the mass of the proton, the mass and electric charge of the electron, the light velocity, Newton's gravitational constant, and the quantum of action of Planck. He adds three of four fundamental laws (e.g., de Broglie's relations connecting particle momentum and particle energy with the wavelength and frequency, and the Pauli exclusion principle), and shows that one can then derive a host of different, apparently quite unconnected, facts that happen to be known to us by observation separately ....
Gerald Holton
Since ancient times artists and architects have seen in the golden mean the most aesthetically satisfying geometric ratio.
Stephen M. Barr
The release of atomic power has changed everything except our way of thinking ... the solution to this problem lies in the heart of mankind. If only I had known, I should have become a watchmaker. (1945)
Albert Einstein
How wonderful that we have met with a paradox. Now we have some hope of making progress.
Niels Bohr
Quantum theory provides us with a striking illustration of the fact that we can fully understand a connection though we can only speak of it in images and parables.
Werner Heisenberg
Time and space are finite in extent, but they don't have any boundary or edge. They would be like the surface of the earth, but with two more dimensions.
Stephen Hawking
God abhors a naked singularity.
Stephen Hawking
Physicists like to think that all you have to do is say, these are the conditions, now what happens next?
Richard Feynman
Give me a place to stand, a lever long enough and a fulcrum. and I can move the Earth
Archimedes
Common sense is the collection of prejudices acquired by age eighteen.
Albert Einstein
If you can't explain it to a six year old, you don't understand it yourself.
Albert Einstein
I am not a genius, I am just curious. I ask many questions. and when the answer is simple, then God is answering.
Albert Einstein
Unconditional love. That’s what he wants to give her and what he wants from her. People should give without wanting anything in return. All other giving is selfish. But he is being selfish a little, isn’t he, by wanting her to love him in return? He hopes that she loves him in return. Is it possible for a person to love without wanting love back? Is anything so pure? Or is love, by its nature, a reciprocity, like oceans and clouds, an evaporating of seawater and a replenishing of rain?
Alan Lightman
Il n'est pas certain que tout soit incertain.(Translation: It is not certain that everything is uncertain.)
Blaise Pascal
Another mistaken notion connected with the law of large numbers is the idea that an event is more or less likely to occur because it has or has not happened recently. The idea that the odds of an event with a fixed probability increase or decrease depending on recent occurrences of the event is called the gambler's fallacy. For example, if Kerrich landed, say, 44 heads in the first 100 tosses, the coin would not develop a bias towards the tails in order to catch up! That's what is at the root of such ideas as "her luck has run out" and "He is due." That does not happen. For what it's worth, a good streak doesn't jinx you, and a bad one, unfortunately , does not mean better luck is in store.
Leonard Mlodinow
If it were possible for a metaphysician to be a golfer, he might perhaps occasionally notice that his ball, instead of moving forward in a vertical plane (like the generality of projectiles, such as brickbats and cricket balls), skewed away gradually to the right. If he did notice it, his methods would naturally lead him to content himself with his caddies's remark-'ye heeled that yin,' or 'Ye jist sliced it.' ... But a scientific man is not to be put off with such flimsy verbiage as that. He must know more. What is 'Heeling', what is 'slicing', and why would either operation (if it could be thoroughly carried out) send a ball as if to cover point, thence to long slip, and finally behind back-stop? These, as Falstaff said, are 'questions to be asked.
Peter Guthrie Tait
The ultimate paradox, of course, is that even though we're all going to die, we've all got to live in the meantime…
Brian Cox
Your theory is crazy, but it's not crazy enough to be true.
Niels Bohr
A question that sometimes drives me hazy: am I or are the others crazy?
Albert Einstein
In no other type of warfare does the advantage lie so heavily with the aggressor." James Franck, The Manhattan Project neatly summarize the atmic bomb.
James Franck
String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.
Edward Witten
We do not belong to this material world that science constructs for us. We are not in it; we are outside. We are only spectators. The reason why we believe that we are in it, that we belong to the picture, is that our bodies are in the picture. Our bodies belong to it. Not only my own body, but those of my friends, also of my dog and cat and horse, and of all the other people and animals. And this is my only means of communicating with them.
Erwin Schrödinger
An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.
Francis Crick
Claims for theoccurrence of miraculous events will have to be evaluated ona case-by-case basis. There can be no general theory to coverthe character of unique events, but the refusal to contemplatethe possibility of revelatory disclosures of an unprecedentedkind would be an unacceptable limitation, imposed arbitrarilyon the horizons of religious thought.
John Polkinghorne
A person functioning exclusively in the Cartesian mode may be free from manifest symptoms but cannot be considered mentally healthy. Such individuals typically lead ego-centred, competitive, goal-oriented lives. Overpreoccupied with their past and their future, they tend to have a limited awarenessof the present and thus a limited ability to derive satisfaction from ordinary activities in everyday life. They concentrate on manipulating the external world and measure their living standard by the quantity of material possessions, while they become ever more alienated from their inner world and unable to appreciate the process of life. For people whose existence is dominated by this mode of experience no level of wealth, power, or fame will bring genuine satisfaction
Fritjof Capra
[Concerning] phosphorescent bodies, and in particular to uranium salts whose phosphorescence has a very brief duration. With the double sulfate of uranium and potassium ... I was able to perform the following experiment: One wraps a Lumière photographic plate with a bromide emulsion in two sheets of very thick black paper, such that the plate does not become clouded upon being exposed to the sun for a day. One places on the sheet of paper, on the outside, a slab of the phosphorescent substance, and one exposes the whole to the sun for several hours. When one then develops the photographic plate, one recognizes that the silhouette of the phosphorescent substance appears in black on the negative. If one places between the phosphorescent substance and the paper a piece of money or a metal screen pierced with a cut-out design, one sees the image of these objects appear on the negative. One can repeat the same experiments placing a thin pane of glass between the phosphorescent substance and the paper, which excludes the possibility of chemical action due to vapors which might emanate from the substance when heated by the sun's rays. One must conclude from these experiments that the phosphorescent substance in question emits rays which pass through the opaque paper and reduces silver
Henri Becquerel
This isn't right. This isn't even wrong.
Wolfgang Pauli
It appears, according to the reported facts, that the electric conflict is not restricted to the conducting wire, but that it has a rather extended sphere of activity around it .. the nature of the circular action is such that movements that it produces take place in directions precisely contrary to the two extremities of a given diameter. Furthermore, it seems that the circular movement, combined with the progressive movement in the direction of the length of the conjunctive wire, should form a mode of action which is exerted as a helix around this wire as an axis.
Hans Christian Ørsted
Never attribute to malice that which can be adequately explained by stupidity, but don't rule out malice.
Albert Einstein
I know that humans are fond of seeing their kind rendered in other media.
Gregory Benford
While it is never safe to affirm that the future of Physical Science has no marvels in store even more astonishing than those of the past, it seems probable that most of the grand underlying principles have been firmly established and that further advances are to be sought chiefly in the rigorous application of these principles to all the phenomena which come under our notice.
Robert S. Mulliken
