Richard Phillips Feynman (1918 - 1988) was an eminent American theoretical physicist known for the integral formulation of the trajectory of quantum mechanics, the theory of quantum electrodynamics and the superfluidity physics of supercooled liquid helium, as well as work in particle physics ( proposed the Parton model).
For his contributions to the development of quantum electrodynamics, Feynman was awarded the Nobel Prize in Physics in 1965. Feynman developed a pictorial representation scheme that is used for mathematical expressions that govern the behavior of subatomic particles, which were later known as Feynman diagrams. During his life and after his death, Feynman became one of the best known physicists in the world and one of the ten most important physicists of all time.
He assisted in the development of the atomic bomb during World War II and became known in the 1980s as a member of the Rogers Commission, the group that investigated the Challenger space shuttle disaster. In addition to his work in theoretical physics, Feynman investigated with pioneers in the field of quantum computing and introduced the concept of nanotechnology. He held the chair of Richard Chace Tolman in theoretical physics at the California Institute of Technology.
Famous quotes by Richard Feynman
The first principle is that you should not deceive yourself and you are the easiest person to deceive. Once you don't fool yourself, it's easy not to fool the other scientists.
What I cannot create, I do not understand.
Even nature itself does not know which path the electron will follow.
Only by working hard can anything be discovered.
Light is not an instant propagation material, it has a speed, and it is finite.
I don't have to 'have' an answer. I don't feel terrified of not knowing things, of being lost in the mysterious universe without having any purpose; which is the way in which reality is, as far as I can possibly say. This does not frighten me.
Science is the belief in the ignorance of experts.
Don't read much, look around and think about what you see there.
I ... a universe of atoms, an atom in the universe.
I would hate to die twice, it's so boring!
The real problem in speech is not language precise. The problem is the language Clear. The desire is to be able to communicate the idea clearly to the other person. It is only necessary to be precise when there is any doubt about the meaning of a sentence, and then the precision must be put in the place where the doubt exists. It is really impossible to say something with absolute precision, unless it is so abstracted from the real world that it does not represent anything real.
In physics, words and formulas are connected to the real world.
You have to have an open mind. But not so much that your brain falls to the ground.
Learn to solve all problems that have already been resolved.
The power of instruction is, in general, ineffective, except in the happy occasions when it is almost superfluous.
We have not found anything wrong in the theory of quantum electrodynamics. Therefore, I would say that it is the jewel of physics, the possession of which we are most proud.
We scientists are smart, too smart, aren't we satisfied? Are not four square miles in a pump enough?
To achieve technological success, reality must be above public relations, because Nature cannot be deceived.
The principle of science, almost the definition, is as follows: "The test of all knowledge is the experiment." The experiment is the only judge of scientific truth.
Physics is like sex: it sure gives some practical compensation, but that is not why we do it.
Antimatter behaves exactly like matter.
I don't know what happens to people: they don't learn by understanding; they learn in some other way, by routine, or in some other way. How fragile is your knowledge!
Principles: You cannot say that A is made of B or vice versa. All mass is interaction.
The same equations have the same solutions.
For those who do not know mathematics, it is difficult to feel the beauty, the deep beauty of nature ... If you want to learn about nature, appreciate nature, it is necessary to learn the language in which you speak.
The theoretical expansion that comes from having many humanities subjects on campus is compensated by the general stupidity of people studying these things.
We have to abandon common sense in order to perceive what is happening at the atomic level.
At that time I discovered something about biology: it was very easy to find a question that was very interesting and that nobody knew how to answer. In physics you had to dig a little deeper to find an interesting question that people could not answer.
Experimental ability, honesty in the publication of the results and intelligence to interpret them.
The most wonderful thing about science is that it is alive.
The world emerged from a more orderly condition in the past than in the present.
The meaning of the phenomena is always towards the loss of available energy.
It is very curious, but on the few occasions that I have been required to play the bongo in public, it never occurred to the presenter to mention that I also dedicate myself to theoretical physics. I think this may be because we respect the arts more than the sciences.
The signals cannot be transmitted beyond the speed of light, so the method of describing instantaneous forces is not viable.
Light has energy, and energy is equivalent to mass; consequently the light also falls.
Currently there is no model of the theory of gravity apart from its mathematical expression.
I am convinced that when a scientist examines non-scientific problems, he can be as clever or as dumb as anyone else, and that when he speaks of a non-scientific matter, he may sound as naive as any person not imposed on the subject.
By the principle of conservation of energy, the mass of an object has to change when moving. The energy related to the movement takes on the appearance of an additional mass, so that the objects become heavier when moving.
There is no theorem that tells us that the interesting things in the world are preserved, only the totality is preserved.
The most important things in nature seem to be the result of chance or accidents.
No one understands quantum physics.
The truly remarkable nature is that the character of the entire universe depends on the position of a specific energy level in a particular nucleus.
The details of the actual experience are often very far from the fundamental laws.
It is not our ignorance, nature possesses probability as something intrinsic to it.
The great architect seems to be a mathematician; Those who do not know mathematics find it really difficult to feel the deep beauty of nature.
A very dim light only means few photons. Seeing electrons implies modifying them.
Man is fascinated by symmetry. We like to see symmetries in nature.
The possibility that the truth is in the fashion direction is high. But, the remote possibility that it is in another direction, an obvious direction from a fashionable vision of field theory, who will find it? Only someone who has sacrificed himself teaching quantum electrodynamics from a peculiar and outdated point of view; one that may have to invent for himself.
The only way that the speed of light is the same for a person at rest and another on the move is that their sense of space and time differ.
The clock of the spaceship that circulates at the speed of light will slow down, but also the brain of the one who wears it.
Quantum mechanics describes nature as something absurd to common sense. But it fully agrees with the experimental tests. Therefore, I hope you can accept nature as it is: absurd.
When you're solving a problem, "don't worry." "After" after you've solved the problem "it's time to worry"
I am not so interested in the human mind as in the wonder of a nature that is capable of obeying a law as simple and as elegant as the law of gravity.
Biology can distinguish between right and left. Neither physics nor chemistry can.
The fact that all molecules of all living things have exactly the same type of spin is probably the deepest demonstration of the uniformity of life's origins.
All fundamental processes are reversible.
It is not contrary to physics, it is simply unlikely.
All this is very confusing, especially when we consider that, although we consider ourselves as external observers when we observe the rest of the world, the rest of the world observes us at the same time, and that often agrees with what we see in others. Does this mean then that my observations become real only when I observe an observer observing something while it happens? This is a horrible point of view. Do you seriously think about the idea that without the observer there is no reality? That observer? Any observer? Is a fly an observer? Is a star an observer? Was there reality in the universe before beginning life? So, is there reality in the world after you're dead? I know several respectable physicists who have bought life insurance.
The future is unpredictable, everything is based on probabilities.
For the existence of science, heads that do not accept that nature must follow certain preconceived conditions are necessary.
The principles of Physics, as I understand them, do not deny the possibility of manipulating things atom by atom.
We are never definitely right.
We must prove our mistakes as quickly as possible, it is the only way forward.
Hell, if I could explain it to the average person, it wouldn't have been worth the Nobel Prize.
Nature's imagination far exceeds ours.
Nature may be completely asymmetrical at the bottom of your heart, but its complexity seems to be symmetrical.
We have the habit of writing articles published in scientific journals so that the work is as complete as possible, to cover all the clues, so as not to worry about dead ends or to describe how we had the wrong idea first, and so on. So there is no place to publish, in a dignified way, what you really did to be able to do the work.
It is possible to recognize the truth for its beauty and simplicity.
What we need is imagination, but imagination curled up in a terrible straitjacket that is knowledge.
Dear Mrs. Chown, ignore your child's attempts to teach him Physics. It is not the most important thing. The most important thing is love. My best wishes, Richard Feynman.
Western civilization, it seems to me, is on par with two great inheritances. One is the scientific spirit of adventure: the adventure towards the unknown, an unknown that must be recognized as unknown in order to be explored; To sum it up - the humility of the intellect. The other great inheritance is Christian ethics, the basis of action on love, the brotherhood of all men, the value of the individual, the humility of the spirit.
