Quotes by Physicists - Page 11

What a wonderful and amazing Scheme have we here of the magnificent Vastness of the Universe! So many Suns, so many Earths, and every one of them stock’d with so many Herbs, Trees and Animals, and adorn’d with so many Seas and Mountains! And how must our wonder and admiration be encreased when we consider the prodigious distance and multitude of the Stars?
Christiaan Huygens
Primary causes are unknown to us; but are subject to simple and constant laws, which may be discovered by observation, the study of them being the object of natural philosophy.Heat, like gravity, penetrates every substance of the universe, its rays occupy all parts of space. The object of our work is to set forth the mathematical laws which this element obeys. The theory of heat will hereafter form one of the most important branches of general physics.
Joseph Fourier
Since only a narrow range of the allowed values for, say, the fine structure constant will permit observers to exist in the Universe, we must find ourselves in the narrow range of possibilities which permit them, no matter how improbable they are. We must ask for the conditional probability of observing constants to take particular ranges, given that other features of the Universe, like its age, satisfy necessary conditions for life.
John D. Barrow
…only in the few universes that are like ours would intelligent beings develop and ask the question: “Why is the universe the way we see it?” The answer is then simple: If it had been any different, we would not be here!
Stephen Hawking
The scientific creation story has majesty, power and beauty. and is infused with a powerful message capable of lifting our spirits in a way that its multitudinous supernatural counterparts are incapable of matching. It teaches us that we are the products of 13.7 billion years of cosmic evolution and the mechanism by which meaning entered the universe, if only for a fleeting moment in time. Because the universe means something to me, and the fact that we are all agglomerations of quarks and electrons in a complex and fragile pattern that can perceive the beauty of the universe with visceral wonder, is, I think, a thought worth raising a glass to this Christmas.
Brian Cox
I believe in the possible. I believe, small though we are, insignificant though we may be, we can reach a full understanding of the universe. You were right when you said you felt small, looking up at all that up there. We are very, very small, but we are profoundly capable of very, very big things.
Stephen Hawking
Matter tells space how to curve, space tells matter how to move.
Albert Einstein
The complex order we now observe [in the universe] could *not* have been the result of any initial design built into the universe at the so-called creation. The universe preserves no record of what went on before the big bang. The Creator, if he existed, left no imprint. Thus he might as well have been nonexistent.
Victor J. Stenger
What place, then, for a creator?
Stephen Hawking
The single most important decision any of us will ever make is whether or not to believe the universe is friendly.
Albert Einstein
Astronomers now find they have painted themselves into a corner because they have proven, by their own methods, that the world began abruptly in an act of creation to which you can trace the seeds of every star, every planet, every living thing in this cosmos and on the earth. And they have found that all this happened as a product of forces they cannot hope to discover. That there are what I or anyone would call supernatural forces at work is now, I think, a scientifically proven fact.
Robert Jastrow
My advice to any heartbroken young girl is to pay close attention to the study of theoretical physics. Because one day there may well be proof of multiple universes. It would not be beyond the realms of possibility that somewhere outside of our own universe lies another different universe. And in that universe, Zayn is still in One Direction.
Stephen Hawking
You are exporting disorder [in the form of heat into the Universe] now as you read this book. You are hastening the demise of everything that exists, bringing forward by your very existence the arrival of time known as the heat death, when all stars have died, all black holes have evaporated away and the entirety of creation is a uniform bath of photons incapable of storing a single bit of information about the glorious adolescence of our wonderful Universe.
Brian Cox
Fine Structure Constant: Fundamental numerical constant of atomic physics and quantum electrodynamics, defined as the square of the charge of the electron divided by the product of Planck's constant and the speed of light.
Steven Weinberg
A clock that is moving through space at a very fast speed does not tick at the same rate as a slow-moving watch gently attached to your wrist as you stroll on a tropical beach. The idea of a universal time - a godlike clock that could somehow sit outside our universe and measure, in one go, the movement of everything in it, how its evolution unfolds, how old it is and all that - does not exist.
Christophe Galfard
I do not feel like an alien in this universe. The more I examine the universe and study the details of its architecture, the more evidence I find that the universe is some sense must have known that we were coming
Freeman Dyson
Away from the safety of your home, the universe was not made for your convenience.
Edward Witten
The universe looks more and more like a great thought rather than a great machine.
James Hopwood Jeans
It is essential to understand our brains in some detail if we are to assess correctly our place in this vast and complicated universe we see all around us.
Francis Crick
Nothing happens until something moves.
Albert Einstein
Now we see how the astronomical evidence supports the Biblical view of the origin of the world. The details differ, but the essential elements in the astronomical and Biblical accounts of Genesis are the same: the chain of events leading to man commenced suddenly and sharply at a definite moment in time, in a flash of light and energy.
Robert Jastrow
Silence is the room we create for the searching of God, where we hear His voice and follow.
Mark Buchanan
Through the reading of popular scientific books I soon reached the conviction that much in the stories of the Bible could not be true. The consequence was a positively fanatic orgy of freethinking coupled with the impression that youth is intentionally being deceived by the state through lies; it was a crushing impression. Mistrust of every kind of authority grew out of this experience, a skeptical attitude toward the convictions that were alive in any specific social environment - an attitude that has never again left me.- Albert Einstein, Autobiographical Notes, edited by Paul Arthur Schilpp
Albert Einstein
I prefer to make up my own quotes and attribute them to very smart people, so that I can use them to win arguments
Albert Einstein
Thoroughly conscious ignorance is the prelude to every real advance in science.
James Clerk Maxwell
I think that in the discussion of natural problems we ought to begin not with the Scriptures, but with experiments and demonstrations.
Galileo Galilei
A few years after I gave some lectures for the freshmen at Caltech (which were published as the Feynman Lectures on Physics), I received a long letter from a feminist group. I was accused of being anti-women because of two stories: the first was a discussion of the subtleties of velocity, and involved a woman driver being stopped by a cop. There's a discussion about how fast she was going, and I had her raise valid objections to the cop's definitions of velocity. The letter said I was making the women look stupid. The other story they objected to was told by the great astronomer Arthur Eddington, who had just figured out that the stars get their power from burning hydrogen in a nuclear reaction producing helium. He recounted how, on the night after his discovery, he was sitting on a bench with his girlfriend. She said, "Look how pretty the stars shine!" To which he replied, "Yes, and right now, I'm the only man in the world who knows how they shine." He was describing a kind of wonderful loneliness you have when you make a discovery. The letter claimed that I was saying a women is incapable of understanding nuclear reactions. I figured there was no point in trying to answer their accusations in detail, so I wrote a short letter back to them: "Don't bug me, Man!
Richard Feynman
Whatever Nature has in store for mankind, unpleasant as it may be, men must accept, for ignorance is never better than knowledge.
Enrico Fermi
Thus identified with astronomy, in proclaiming truths supposed to be hostile to Scripture, Geology has been denounced as the enemy of religion. The twin sisters of terrestrial and celestial physics have thus been joint-heirs of intolerance and persecution—unresisting victims in the crusade which ignorance and fanaticism are ever waging against science. When great truths are driven to make an appeal to reason, knowledge becomes criminal, and philosophers martyrs. Truth, however, like all moral powers, can neither be checked nor extinguished. When compressed, it but reacts the more. It crushes where it cannot expand—it burns where it is not allowed to shine. Human when originally divulged, it becomes divine when finally established. At first, the breath of a rage—at last it is the edict of a god. Endowed with such vital energy, astronomical truth has cut its way through the thick darkness of superstitious times, and, cheered by its conquests, Geology will find the same open path when it has triumphed over the less formidable obstacles of a civilized age.
David Brewster
According to the conclusion of Dr. Hutton, and of many other geologists, our continents are of definite antiquity, they have been peopled we know not how, and mankind are wholly unacquainted with their origin.
Jean-André de Luc
People often mistake their imagination for their heart, & so often are convinced they are converted as soon as they start thinking of becoming converted.
Blaise Pascal
I received your letter of June 10th. I have never talked to a Jesuit priest in my life and I am astonished by the audacity to tell such lies about me. From the viewpoint of a Jesuit priest I am, of course, and have always been an atheist.
Albert Einstein
Whoever is careless with the truth in small matters cannot be trusted with important matters
Albert Einstein
I learned from her that every woman is worriedabout her looks, no matter how beautiful she is.
Richard Feynman
As the blood poured from his tattered heart into the open air and his brain suffocated, all those incomplete thoughts of Wittgenstein decayed with the dying neurons. Neural connections in the gray matter storing memories and ideas in their ordered configurations fired across the gaps, last gaps of mental life. Thoughts on Truth and Will were erased as flesh sloshed soft and limp against alabaster, no more than rotting human fruit.
Janna Levin
There is a deep and perennial and profoundly human impulse to approach the world with a DEMAND, to approach the world with a PRECONDITION, that what has got to turn out to lie at THE CENTER OF THE UNIVERSE, that what has got to turn out to lie at THE FOUNDATION OF ALL BEING, is some powerful and reassuring and accessible image of OURSELVES... and that, more than any of their particular factual inaccuracies - is what bothers me the most about them. It is precisely the business of resisting that demand, it is precisely the business of approaching the world with open and authentic wonder, and with a sharp, cold eye, and singularly intent upon the truth, that's called science.
David Z. Albert
The fastest that human spacecraft are likely to achieve in the twenty-first century, I think, is 300 kilometres per second.
Kip S. Thorne
True human progress is based less on the inventive mind than on the conscience of such men as Brandeis.~ Albert Einstein
Albert Einstein
I fear the day that technology will surpass our human interaction. The world will have a generation of idiots.
Albert Einstein
We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet,
Stephen Hawking
It is my view that the vegetarian manner of living, by its purely physical effect on the human temperament, would most beneficially influence the lot of mankind.
Albert Einstein
Frederick Douglass told in his Narrative how his condition as a slave became worse when his master underwent a religious conversion that allowed him to justify slavery as the punishment of the children of Ham. Mark Twain described his mother as a genuinely good person, whose soft heart pitied even Satan, but who had no doubt about the legitimacy of slavery, because in years of living in antebellum Missouri she had never heard any sermon opposing slavery, but only countless sermons preaching that slavery was God's will. With or without religion, good people can behave well and bad people can do evil; but for good people to do evil — that takes religion.
Steven Weinberg
Humanity's moral conscience progresses, slowly yet surely...
Cheikh Anta Diop
I swear to use my scientific knowledge for the good of Humanity. I promise never to harm any person in my search for enlightenment.I shall be courageous and careful in my quest for greater knowledge about the mysteries that surround us. I shall not use scientific knowledge for my own personal gain or give it to those who seek to destroy the wonderful planet on which we live.If I break this oath, may the beauty and wonder of the Universe forever remain hidden from me.
Stephen Hawking
A man's ethical behavior should be based effectually on sympathy, education, and social ties and needs; no religious basis is necessary. Man would be in a poor way if he had to be restrained by fear of punishment and hopes of reward after death.
Albert Einstein
Morality existed only in action. It arose out of action: was formed and tested in action: expressed itself in action. That was why we mustn't cheapen it with words
C.P. Snow
No doubt there are some who, when confronted with a line of mathematical symbols, however simply presented, can only see the face of a stern parent or teacher who tried to force into them a non-comprehending parrot-like apparent competence--a duty and a duty alone--and no hint of magic or beauty of the subject might be allowed to come through.
Roger Penrose
Never express yourself more clearly than you are able to think.
Niels Bohr
Most people avoid thinking if they can, some of us are addicted to thinking, but Von Neumann actually enjoyed thinking, maybe even to the exclusion of everything else.
Edward Teller
Man is but a reed, the weakest in nature, but he is a thinking reed.
Blaise Pascal
All of science is nothing more than the refinement of everyday thinking.
Albert Einstein
Humor, motivations, moral,gods,energy,secrecy
Albert Einstein
We shall require a substantially new manner of thinking if mankind is to survive.
Albert Einstein
The unleashed power of the atom has changed everything except our thinking. Thus, we are drifting toward catastrophe beyond conception. We shall require a substantially new manner of thinking if mankind is to survive.
Albert Einstein
We can not solve our problems with the same level of thinking that created them
Albert Einstein
The knowledge of God without that of man's misery causes pride. The knowledge of man's misery without that of God causes despair. The knowledge of Jesus Christ is the middle course, because in Him we find both God and our misery.
Blaise Pascal
If we do not know ourselves to be full of pride, ambition, lust, weakness, misery, and injustice, we are indeed blind. And if, knowing this, we do not desire deliverance, what can we say of a man...?
Blaise Pascal
A good many times I have been present at gatherings of people who, by the standards of the traditional culture, are thought highly educated and who have with considerable gusto been expressing their incredulity at the illiteracy of scientists. Once or twice I have been provoked and have asked the company how many of them could describe the Second Law of Thermodynamics. The response was cold: it was also negative. Yet I was asking something which is about the scientific equivalent of: Have you read a work of Shakespeare's?
C.P. Snow
It is good to recall that three centuries ago, around the year 1660, two of the greatest monuments of modern history were erected, one in the West and one in the East; St. Paul's Cathedral in London and the Taj Mahal in Agra. Between them, the two symbolize, perhaps better than words can describe, the comparative level of architectural technology, the comparative level of craftsmanship and the comparative level of affluence and sophistication the two cultures had attained at that epoch of history. But about the same time there was also created—and this time only in the West—a third monument, a monument still greater in its eventual import for humanity. This was Newton's Principia, published in 1687. Newton's work had no counterpart in the India of the Mughals.
Abdus Salam
Suppose we were able to share meanings freely without a compulsive urge to impose our view or conform to those of others and without distortion and self-deception. Would this not constitute a real revolution in culture?
David Bohm
