No human investigation can claim to be scientific if it doesn't pass the test of mathematical proof.

I conceive that the leading characteristic of the nineteenth century has been the rapid growth of the scientific spirit, the consequent application of scientific methods of investigation to all the problems with which the human mind is occupied, and the correlative rejection of traditional beliefs which have proved their incompetence to bear such investigation.
[On Archimedes mathematical results:] It is not possible to find in all geometry more difficult and intricate questions, or more simple and lucid explanation... No investigation of yours would succeed in attaining the proof, and yet, once seen you immediately believe you would have discovered it.
A modern mathematical proof is not very different from a modern machine, or a modern test setup: the simple fundamental principles are hidden and almost invisible under a mass of technical details.
The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind.
The natural scientist is concerned with a particular kind of phenomena ... he has to confine himself to that which is reproducible ... I do not claim that the reproducible by itself is more important than the unique. But I do claim that the unique exceeds the treatment by scientific method. Indeed it is the aim of this method to find and test natural laws.
The notion that the levels of radiation would be damaging to human life is preposterous. It's simply not true. It is a political claim more than it is a scientific claim. THAAD has been a thoroughly tested system, and it has been extremely effective.
As soon as a man stands up and says he is right or his church is right, and all others are wrong, he is himself all wrong. He does not know that upon the proof of all the others depends the proof of his own. Love and charity for the whole human race, that is the test of true religiousness. I do not mean the sentimental statement that all men are brothers, but that one must feel the oneness of human life.
The only way to pass any test is to take the test. All tests on every level are always repeated one way or another until you pass.
The human heart would never pass the drunk test.... If you took the human heart out of the human body and put a pair of legs on it and told it to walk a straight line, it couldn't do it.
Statistics is, or should be, about scientific investigation and how to do it better, but many statisticians believe it is a branch of mathematics. Now I agree that the physicist, the chemist, the engineer, and the statistician can never know too much mathematics, but their objectives should be better physics, better chemistry, better engineering, and in the case of statistics, better scientific investigation. Whether in any given study this implies more or less mathematics is incidental.
Trauma and sexual abuse are two of our most pressing human and societal problems. They must be studied by unbiased scientific investigation rather than polarized by hysteria and politics.
We all have friends we love dearly that couldn't pass for human in a strict Turing test.
I see myself as a spiritual person, but I don't think anyone should claim proof of a god. No one can prove it. That's why I don't claim to know whether there are one, many or no gods.
What a mathematical proof actually does is show that certain conclusions, such as the irrationality of , follow from certain premises, such as the principle of mathematical induction. The validity of these premises is an entirely independent matter which can safely be left to philosophers.
The test, surely, of a creed is not the ability of those who accept it to announce their faith; its test is its ability to change their behavior in the ordinary round of daily life. Judged by that test, I know no religion that has a moral claim upon the allegiance of men.
You should have to pass an IQ test before you breed. You have to take a driving test to operate vehicles and an SAT test to get into college. So why don’t you have to take some sort of test before you give birth to children? When I am President, that’s the first rule I will institute.
