Physicist quotes

Concepts that have proven useful in ordering things easily achieve such authority over us that we forget their earthly origins and accept them as unalterable givens.
Albert Einstein
Many people would claim that the boundary conditions are not part of physics but belong to metaphysics or religion. They would claim that nature had complete freedom to start the universe off any way it wanted. That may be so, but it could also have made it evolve in a completely arbitrary and random manner. Yet all the evidence is that it evolves in a regular way according to certain laws.
Stephen Hawking religion

In the last analysis, we ourselves are part ofand therefore part of thethat we are trying to solve.
Max Planck art
The old , such as the relation ofand , are still with us, and Ipresent as difficult dilemmas as ever, but they are not often publicly discussed because of the limitations of specialization.
Richard Feynman present
I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be.
William Thomson knowledge
I have always believed that astrophysics should be the extrapolation of laboratory physics, that we must begin from the present universe and work our way backward to progressively more remote and uncertain epochs.

On even the worst days, when nothing was working at the lab, I knew that at home I would find warmth, peace, companionship, and encouragement. As a consequence, the next day would surely be better.
James Cronin war
Is it right to probe so deeply into Nature's secrets? The question must here be raised whether it will benefit mankind, or whether the knowledge will be harmful.
Pierre Curie knowledge
The electron can no longer be conceived as a single, small granule of electricity; it must be associated with a wave, and this wave is no myth; its wavelength can be measured and its interferences predicted.
Louis de Broglie sin
God used beautiful mathematics in creating the world.
Paul Dirac world
Technology is a gift of God. After the gift of life it is perhaps the greatest of God's gifts. It is the mother of civilizations, of arts and of sciences.
Freeman Dyson life
The important thing is to know how to take all things quietly.
Michael Faraday
The fundamental point in fabricating a chain reacting machine is of course to see to it that each fission produces a certain number of neutrons and some of these neutrons will again produce fission.
Enrico Fermi men
The phenomenon develops calmly, but it is invisible, unstoppable. One feels, one sees it born and grow steadily; and it is not in one's power to either hasten or slow it down.

Enthusiasm is followed by disappointment and even depression, and then by renewed enthusiasm.
Murray Gell Mann men
In the discovery of secret things and in the investigation of hidden causes, stronger reasons are obtained from sure experiments and demonstrated arguments than from probable conjectures and the opinions of philosophical speculators of the common sort.
William Gilbert men
Science is a way of life. Science is a perspective. Science is the process that takes us from confusion to understanding in a manner that's precise, predictive and reliable - a transformation, for those lucky enough to experience it, that is empowering and emotional.
Brian Greene life
We thought it would be nice to have atoms interact in such a gentle way with the photons that they would just take an imprint of the photons, so that many atoms could 'see' the same photon and it would give rise to a lot of interesting effects. Myself and my colleagues had this project for a very long time and we were finally able to observe it.
Serge Haroche time
The solution of the difficulty is that the two mental pictures which experiment lead us to form - the one of the particles, the other of the waves - are both incomplete and have only the validity of analogies which are accurate only in limiting cases.

Hermann von Helmholtz body
The investigation into the possible effects of cosmic rays on living organisms will also offer great interest.
Victor Francis Hess living
In 2002, a Scottish journalist, during a dinner meant to be private, absolutely wanted me to react to Stephen Hawking's comments. I said one shouldn't pay too much attention to what Hawking was saying because he was a celebrity but not a specialist of elementary particle theory.
Peter Higgs art
The Nobel Prize is given as a personal award but it also honors the field of research in which I have worked and it also honors my students and colleagues.

Erwin Schrödinger great
Order is manifestly maintained in the universe... governed by the sovereign will of God.
James Prescott Joule man
Some advice: keep the flame of curiosity and wonderment alive, even when studying for boring exams. That is the well from which we scientists draw our nourishment and energy. And also, learn the math. Math is the language of nature, so we have to learn this language.
Michio Kaku nature
I must confess that, at that time, I had absolutely no knowledge of the slowness of the relaxation processes in the ground state, processes which take place in collisions with the wall or with the molecules of a foreign gas.
Alfred Kastler knowledge
I have to ask Allahs forgiveness and not get angry, because they come to me out of love, and its not fitting that I should turn to them in hatred.

Leo Szilard world
The science of today is the technology of tomorrow.
Edward Teller science
Many have argued that a vacuum does not exist, others claim it exists only with difficulty in spite of the repugnance of nature; I know of no one who claims it easily exists without any resistance from nature.

Since we can produce all types of light by means of hot bodies, we can ascribe, to the radiation in thermal equilibrium with hot bodies, the temperature of these bodies, and thus every radiation, even that issuing from a phosphorescent body, has a certain temperature for every colour.
Wilhelm Wien light
Physics is becoming so unbelievably complex that it is taking longer and longer to train a physicist. It is taking so long, in fact, to train a physicist to the place where he understands the nature of physical problems that he is already too old to solve them.
Eugene Wigner nature
It is essential for genetic material to be able to make exact copies of itself; otherwise growth would produce disorder, life could not originate, and favourable forms would not be perpetuated by natural selection.
Maurice Wilkins life
We know a lot of things, but what we dont know is a lot more.
Edward Witten
Einsteins theory has the very highest degree of æsthetic merit: every lover of the beautiful must wish it to be true. It gives a vast unified survey of the operations of nature, with a technical simplicity in the critical assumptions which makes the wealth of deductions astonishing. It is a case of an advance arrived at by pure theory: the whole effect of Einsteins work is to make physics more philosophical in a good sense, and to restore some of that intellectual unity which belonged to the great scientific systems of the seventeenth and eighteenth centuries, but which was lost through increasing specialization and the overwhelming mass of detailed knowledge. In some ways our age is not a good one to live in, but for those who are interested in physics there are great compensations.
Hendrik Lorentz love
On the basis of Lorentzs theory, if we limit ourselves to a single spectral line, it suffices to assume that each atom (or molecule) contains a single moving electron.
