Quotes by Physicists - Page 8

To Nature nothing can be added; from Nature nothing can be taken away; the sum of her energies is constant, and the utmost man can do in the pursuit of physical truth, or in the applications of physical knowledge, is to shift the constituents of the never-varying total. The law of conservation rigidly excludes both creation and annihilation. Waves may change to ripples, and ripples to waves; magnitude may be substituted for number, and number for magnitude; asteroids may aggregate to suns, suns may resolve themselves into florae and faunae, and floras and faunas melt in air: the flux of power is eternally the same. It rolls in music through the ages, and all terrestrial energy—the manifestations of life as well as the display of phenomena—are but the modulations of its rhythm.
John Tyndall
If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.
Nikola Tesla
Details that could throw doubt on your interpretation must be given, if you know them. You must do the best you can—if you know anything at all wrong, or possibly wrong—to explain it. If you make a theory, for example, and advertise it, or put it out, then you must also put down all the facts that disagree with it, as well as those that agree with it. There is also a more subtle problem. When you have put a lot of ideas together to make an elaborate theory, you want to make sure, when explaining what it fits, that those things it fits are not just the things that gave you the idea for the theory; but that the finished theory makes something else come out right, in addition.
Richard Feynman
To the very last, the desire to challenge oneself and understand more. And to the very last: doubt.
Carlo Rovelli

Nicanor Parra
I... a universe of atoms, an atom in the universe.
Richard Feynman
Questions of personal priority, however interesting they may be to the persons concerned, sink into insignificance in the prospect of any gain of deeper insight into the secrets of nature.
William Thomson
There are no secrets about the world of nature. There are secrets about the thoughts and intentions of men.
J. Robert Oppenheimer
I am thankful for all of those who said NO to me. It's because of them I'm doing it myself.
Albert Einstein
A first-rate laboratory is one in which mediocre scientists can produce outstanding work.
P.M.S. Blackett
The scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of very great importance, I think. When a scientist doesn’t know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty damn sure of what the result is going to be, he is still in some doubt. We have found it of paramount importance that in order to progress, we must recognize our ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty — some most unsure, some nearly sure, but none absolutely certain. Now, we scientists are used to this, and we take it for granted that it is perfectly consistent to be unsure, that it is possible to live and not know. But I don’t know whether everyone realizes this is true. Our freedom to doubt was born out of a struggle against authority in the early days of science. It was a very deep and strong struggle: permit us to question — to doubt — to not be sure. I think that it is important that we do not forget this struggle and thus perhaps lose what we have gained.
Richard Feynman
[To] mechanical progress there is apparently no end: for as in the past so in the future, each step in any direction will remove limits and bring in past barriers which have till then blocked the way in other directions; and so what for the time may appear to be a visible or practical limit will turn out to be but a bend in the road.(Opening address to the Mechanical Science Section, Meeting of the British Association, Manchester.)
Osborne Reynolds
We must realize that growth is but an adolescent phase of life which stops when physical maturity is reached. If growth continues in the period of maturity it is called obesity or cancer. Prescribing growth as the cure for the energy crisis has all the logic of prescribing increasing quantities of food as a remedy for obesity.
Albert A. Bartlett
The markets make a good servant but a bad master, and a worse religion.
Amory B. Lovins
It's easy to make money when you have a lot of it.
Max Tegmark
The Pharisees had an ethic of avoidance, and Jesus had an ethic of involvement.
Mark Buchanan
For the place God calls us into isn’t doubt free—how can any place where we walk by faith and not by sight be that? No, the holy wild is where we have driving and haunting doubts, God-hungry doubts that pull us to our knees, force us to the Word, make us wrestle all night and not let go until He blesses us. The holy wild throngs with true skeptics.
Mark Buchanan
God’s definition of going well is unique, distinct, almost eccentric. His definition of wellness is not about health, finances, or job security. It’s not about unfailing protection from the vagaries and dangers of a broken world. It’s not about life being fair. It’s about acceptance.
Mark Buchanan
Laughter—just good bone-shaking, belly-jiggling, light-in-the-head laughter, is a sure sign of health. The only one who hates it is Satan and all his wannabes.
Mark Buchanan
We honestly think that we ourselves and those around us should be proficient with spiritual power, moving and acting with agility and endurance, wisdom and purity, able to conquer long-established habits of sloth and rebelliousness, simply on the basis of our desire and effort and sincerity...We have to train for the spiritual life.
Mark Buchanan
We're all born with curiosity, but at some point, school usually manages to knock that out of us.
Max Tegmark
Interestingly enough, whenever I cite examples from superhero comic books in a lecture, my students never wonder when they will use this information in their "real life". Apparently they all have plans, post-graduation, that involve protecting the City from all threat while wearing spandex. As a law-abiding citizen, this notion fills me with a great sense of security, knowing as I do how many of my scientist colleagues could charitably be termed "mad".
James Kakalios
As a kid I was deeply curious as to what college life would be like. Now that I am a university professor, I realize that this was a premonition that once I entered college I would never get out, and that my matriculation would turn into some sort of life sentence.
James Kakalios
One had to cram all this stuff into one's mind for the examinations, whether one liked it or not. This coercion had such a deterring effect on me that, after I had passed the final examination, I found the consideration of any scientific problems distasteful to me for an entire year.
Albert Einstein

Nicanor Parra
We cannot despair of humanity, since we ourselves are human beings.
Albert Einstein
We humans are confined to our brane.
Kip S. Thorne
Humans and animals regard each other across a gulf of mutual incomprehension. With aliens, that has to go double.
Gregory Benford
The beauty in the genome is of course that it's so small. The human genome is only on the order of a gigabyte of data...which is a tiny little database. If you take the entire living biosphere, that's the assemblage of 20 million species or so that constitute all the living creatures on the planet, and you have a genome for every species the total is still about one petabyte, that's a million gigabytes - that's still very small compared with Google or the Wikipedia and it's a database that you can easily put in a small room, easily transmit from one place to another. And somehow mother nature manages to create this incredible biosphere, to create this incredibly rich environment of animals and plants with this amazingly small amount of data.
Freeman Dyson
The art of opposition and of revolution is to unsettle established customs, sounding them even to their source, to point out their want of authority and justice.
Blaise Pascal
I do not believe in the immortality of the individual, and I consider ethics to be an exclusively human concern without any superhuman authority behind it.
Albert Einstein
Profound thoughts arise only in debate, with a possibility of counterargument, only when there is a possibility of expressing not only correct ideas, but also dubious ideas.
Andrei Sakharov
For an idea that does not first seem insane, there is no hope.
Albert Einstein

Francis Crick
This dog is mine," said those poor children; "that is my place in the sun." Here is the beginning and the image of the usurpation of all the earth.
Blaise Pascal
This crippling of individuals I consider the worst evil of capitalism. Our whole educational system suffers from this evil. An exaggerated competitive attitude is inculcated into the student, who is trained to worship acquisitive success as a preparation for his future career.
Albert Einstein
Private capital tends to become concentrated in few hands, partly because of competition among the capitalists, and partly because technological development and the increasing division of labor encourage the formation of larger units of production at the expense of smaller ones. The result of these developments is an oligarchy of private capital the enormous power of which cannot be effectively checked even by a democratically organized political society. This is true since the members of legislative bodies are selected by political parties, largely financed or otherwise influenced by private capitalists who, for all practical purposes, separate the electorate from the legislature. The consequence is that the representatives of the people do not in fact sufficiently protect the interests of the underprivileged sections of the population. Moreover, under existing conditions, private capitalists inevitably control, directly or indirectly, the main sources of information (press, radio, education). It is thus extremely difficult, and indeed in most cases quite impossible, for the individual citizen to come to objective conclusions and to make intelligent use of his political rights.
Albert Einstein
Production is carried on for profit, not for use. There is no provision that all those able and willing to work will always be in a position to find employment; an “army of unemployed” almost always exists. The worker is constantly in fear of losing his job. Since unemployed and poorly paid workers do not provide a profitable market, the production of consumers’ goods is restricted, and great hardship is the consequence. Technological progress frequently results in more unemployment rather than in an easing of the burden of work for all. The profit motive, in conjunction with competition among capitalists, is responsible for an instability in the accumulation and utilization of capital which leads to increasingly severe depressions. Unlimited competition leads to a huge waste of labor, and to that crippling of the social consciousness of individuals which I mentioned before.
Albert Einstein
All he did all afternoon was calculate again and again how many hours of study time he was losing. Thinking about it now, he felt stupid, as we all do when we remember all the time we waste wishing we were somewhere else.
Paolo Giordano
She was stung by sharp regret thinking about the sheets and tablecloths, so costly and never used due to excessive regard.
Paolo Giordano
Mattia thought that he and Alice were like that, twin primes, alone and lost, close but not close enough to really touch each other.
Paolo Giordano
Anyone who has never made a mistake has never tried anything new.
Albert Einstein
A scientist has to be neutral in his search for the truth, but he cannot be neutral as to the use of that truth when found. If you know more than other people, you have more responsibility, rather than less.
C.P. Snow
As was the case for Nobel's own invention of dynamite, the uses that are made of increased knowledge can serve both beneficial and potentially harmful ends. Increased knowledge clearly implies increased responsibility.
Nicolaas Bloembergen
Racism is a disease of white people
Albert Einstein
There is no democracy in physics. We can't say that some second-rate guy has as much right to opinion as Fermi.
Luis Walter Alvarez
Now if there is anything in this universe for which we do not have an "inkling," it is the ultimate goal of the Creator. Erroneous notions regarding this goal often stem from the misconception that all existence exists for man alone. The foible in this perception of the universe is the failure to realize that existence itself is good. The Five Books of Moses are bracketed by explicit statements of the worth of being. At the start we are told: "And God saw all that was made and behold it was very good" (Gen. 1:31)
Gerald Schroeder
Man, made after God's image, was a nobler creation than twinkling sparks in the sky, or than the larger and more useful lamp of the moon.
David Brewster
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
We, the atom and I, have been on friendly terms, until recently. I saw in it the key to the deepest secrets of Nature, and it revealed to me the greatness of creation and the Creator.
Max Born
What is it that has called you so suddenly out of nothingness to enjoy for a brief while a spectacle which remains quite indifferent to you? The conditions for your existence are almost as old as the rocks. For thousands of years men have striven and suffered and begotten and women have brought forth in pain. A hundred years ago, perhaps, another man sat on this spot; like you he gazed with awe and yearning in his heart at the dying light of the glaciers. Like you he was begotten of man and born of woman. He felt pain and brief joy as you do. Was he someone else? Was it not you yourself? What is this Self of yours? What was the necessary condition for making the thing conceived this time into you, just you and not someone else? What clearly intelligible scientific meaning can this 'someone else' really have? If she who is now your mother had cohabited with someone else and had a son by him, and your father had done likewise, would you have come to be? Or were you living in them, and in your father's father... thousands of years ago? And even if this is so, why are you not your brother, why is your brother not you, why are you not one of your distant cousins? What justifies you in obstinately discovering this difference - the difference between you and someone else - when objectively what is there is the same?
Erwin Schrödinger
It is not easy to convey, unless one has experienced it, the dramatic feeling of sudden enlightenment that floods the mind when the right idea finally clicks into place. One immediately sees how many previously puzzling facts are neatly explained by the new hypothesis. One could kick oneself for not having the idea earlier, it now seems so obvious. Yet before, everything was in a fog.
Francis Crick
I noticed that the [drawing] teacher didn't tell people much... Instead, he tried to inspire us to experiment with new approaches. I thought of how we teach physics: We have so many techniques - so many mathematical methods - that we never stop telling the students how to do things. On the other hand, the drawing teacher is afraid to tell you anything. If your lines are very heavy, the teacher can't say, "Your lines are too heavy." because *some* artist has figured out a way of making great pictures using heavy lines. The teacher doesn't want to push you in some particular direction. So the drawing teacher has this problem of communicating how to draw by osmosis and not by instruction, while the physics teacher has the problem of always teaching techniques, rather than the spirit, of how to go about solving physical problems.
Richard Feynman
I never teach my pupils, I only attempt to provide the conditions in which they can learn.
Albert Einstein
Taking him for all and all, I think it will be conceded that Michael Faraday was the greatest experimental philosopher the world has ever seen.
John Tyndall
The scientist is not responsible for the laws of nature. It is his job to find out how these laws operate. It is the scientist’s job to find the ways in which these laws can serve the human will. However, it is not the scientist’s job to determine whether a hydrogen bomb should be constructed, whether it should be used, or how it should be used. This responsibility rests with the American people and with their chosen representatives.
Edward Teller
I think it is a duty I owe to my profession and to my sex to show that a woman has a right to the practice of her profession and cannot be condemned to abandon it merely because she marries. I cannot conceive how women's colleges, inviting and encouraging women to enter professions can be justly founded or maintained denying such a prin
Harriet Brooks
All Mattia saw was a shadow moving toward him. He instinctively closed his eyes and then felt Alice’s hot mouth on his, her tears on his cheek, or maybe they weren’t hers, and finally her hands, so light, holding his head still and catching all his thoughts and imprisoning them there, in the space that no longer existed between them.
Paolo Giordano
I consider it extremely doubtful whether the happiness of the human race has been enhanced by the technical and industrial developments that followed in the wake of rapidly progressing natural science.
Erwin Schrödinger
Men seek rest in a struggle against difficulties; and when they have conquered these, rest becomes insufferable.
Blaise Pascal
