A Quote by Seth Lloyd
Unlike mathematical theorems, scientific results can't be proved. They can only be tested again and again, until only a fool would not believe them. I cannot prove that electrons exist..........if you don't believe in them I have a high voltage cattle prod I'm willing to apply as an argument on their behalf. Electrons speak for themselves.

If all sentient beings in the universe disappeared, there would remain a sense in which mathematical objects and theorems would continue to exist even though there would be no one around to write or talk about them. Huge prime numbers would continue to be prime, even if no one had proved them prime.
Democracy is not a mathematical deduction proved once and for all time. Democracy is a just faith fervently held, commitment to be tested again and again in the fiery furnace of history.
When a photon comes down, it interacts with electrons throughout the glass, not just on the surface. The photon and electrons do some kind of dance, the net result of which is the same as if the photon hit only on the surface.
Philosophers often think all scientists must be scientific realists. If you ask a simple question like "Are electrons real?" the answer will be "Yes". But if your questions are less superficial, for example whether some well-known scientist was a good scientist. Then, they had insisted that only empirical criteria matter and that they actually did not believe in the reality of sub-atomic entities. Ask "If that turned out to be true, would you still say they were good scientists?" The answer would reveal something about how they themselves understood what it is to be a scientist.
If people depend on me to be a man of truth, I have to prove again and again and again and again that I am a man of truth. It cannot be that on Monday I am a man of truth, on Tuesday I speak three-quarters truth, Wednesday I speak half-truth, on Thursday I speak one-quarter truth, on Friday I don't speak at all, and on Saturday I can't even think how to speak the truth.
If you bang two electrons together with enough energy, you produce protons. If there are no independent laws, then all the properties of protons must somehow be 'known' by the electrons. By extension, every elementary particle must carry around enough information to produce the entire universe. I find that difficult to believe.
So if we're all quarks and electrons ..." he begins. What?" We could make love and it would be nothing more than quarks and electrons rubbing together." Better than that," I say. "Nothing really 'rubs together' in the microscopic world. Matter never really touches other matter, so we could make love without any of our atoms touching at all. Remember that electrons sit on the outside of atoms, repelling other electrons. So we could make love and actually repel each other at the same time.
When you sit in a chair, you are not actually sitting there, but levitating above it at a height of one angstrom (a hundred millionth of a centimetre), your electrons and its electrons implacably opposed to any closer intimacy.
Certainly there are things worth believing. I believe in the brotherhood of man and the uniqueness of the individual. But if you ask me to prove what I believe, I can't. You know them to be true but you could spend a whole lifetime without being able to prove them. The mind can proceed only so far upon what it knows and can prove. There comes a point where the mind takes a leap—call it intuition or what you will—and comes out upon a higher plane of knowledge, but can never prove how it got there. All great discoveries have involved such a leap.
Memory runs along deep, fixed channels in the brain, like electricity along its conduits; only a cataclysm can make the electrons rear up in shock and slide over into another channel. The human mind seems doomed to believe, as simply as a rooster believes, that where we are now is the only possibility
Mathematics is not only real, but it is the only reality. That is that entire universe is made of matter, obviously. And matter is made of particles. It's made of electrons and neutrons and protons. So the entire universe is made out of particles. Now what are the particles made out of They're not made out of anything. The only thing you can say about the reality of an electron is to cite its mathematical properties. So there's a sense in which matter has completely dissolved and what is left is just a mathematical structure.
As I said in the Times and will say again here, I do, however, believe that most members of our community - as well as the majority of heterosexuals - cannot and do not choose the gender of the persons with whom they seek to have intimate relationships because, unlike me, they are only attracted to one sex.
If they had only themselves to consider, lovers would not need to marry, but they must think of others and of other things. They say their vows to the community as much as to one another, and the community gathers around them to hear and to wish them well, on their behalf and its own. It gathers around them because it understands how necessary, how joyful, and how fearful this joining is. These lovers, pledging themselves to one another "until death," are giving themselves away, and they are joined by this as no law or contract could join them.
Atoms consist of a positive nucleus and negative electrons flying around outside it. Electrons closest to the nucleus feel a strong negative-on-positive tug, and the bigger atoms get, the bigger the tug. In really big atoms, electrons whip around at speeds close to the speed of light.
You don't believe that the Earth is round only if you're an astronaut. You don't believe Napoleon existed only if you're a historian. You believe these things because they're facts, proved by evidence.
Those who assert that the mathematical sciences say nothing of the beautiful or the good are in error. For these sciences say and prove a great deal about them; if they do not expressly mention them, but prove attributes which are their results or definitions, it is not true that they tell us nothing about them. The chief forms of beauty are order and symmetry and definiteness, which the mathematical sciences demonstrate in a special degree.
