A Quote by Brian Schmidt
There can be theory but, you know, the problem is you've got to be able to test it. So theories are one thing, testing is another.

The obvious thing is I would love to fight Conor McGregor. We've got some history there, and he won, and people saying he didn't knock me out because of an injury he had. I was injured in the fight, too, so let's test that theory. I want to test that theory.
Managers are already voracious consumers of theory. Every time they make a decision or take action, it's based on some theory that leads them to believe that action will lead to the right result. The problem is, most managers aren't aware of the theories they're using, and they often use the wrong theories for the situation.
... it is a fundamental principle of testing that you must know in advance the answer each test case is supposed to produce. If you don't, you are not testing; you are experimenting.
By the time I got into test work, it was dying out. It wasn't really flight test at all; it was mostly testing new gadgets.
Evolution has long been badly taught. In particular, students - and even professional biologists - acquire theories of evolution without any deep understanding of what problem these theories attempt to solve. They learn but little of the evolution of evolutionary theory.
People are always asking for the latest developments in the unification of this theory with that theory, and they don't give us a chance to tell them anything about one of the theories that we know pretty well. They always want to know things that we don't know.
If testing costs more than not testing, then don't test.
Superstring theories provide a framework in which the force of gravity may be united with the other three forces in nature: the weak, electromagnetic and strong forces. Recent progress has shown that the most promising superstring theories follow from a single theory. For the last generation, physicists have studied five string theories and one close cousin. Recently it has become clear that these five or six theories are different limiting cases of one theory which, though still scarcely understood, is the candidate for superunification of the forces of nature.
Newton's theory is not 'not right', it just does not cover all distances. Contrary to popular belief, theories in science are not proven wrong, they are just replaced by more complete and convenient theories. To sound provocative, even the geocentric theory was never "proven" wrong, it is just not as convenient as the heliocentric theory, since it requires endless epicycles.
It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that the only thing that quantum theory has going for it is that it is unquestionably correct.
Scientific theories need reconstruction every now and then. If they didn't need reconstruction they would be facts, not theories. The more facts we know, the less radical become the changes in our theories. Hence they are becoming more and more constant. But take the theory of gravitation; it has not been changed in four hundred years.
Many theories of the ancient world seem terribly childish today, a hodge-podge of fables and false comparisons.But our theories will seem childish five-hundred years from now.Every theory is based on some analogy, and sooner or later the theory fails because the analogy turns out to be false. A theory in its day helps to solve the problems of the day.
Evidence-based reasoning underpins all scientific thinking, and it involves testing hypotheses or theories against data. Validating a theory requires replicable measurements from independent groups with different equipment and methods of analysis. Convergence of evidence is critical to the acceptance of a scientific idea.
Rose: "I was testing dorm security. It sucks." Dimitri: "You must be freezing. Do you want my coat?" Rose: "I'm fine. What are you doing out here? Are you testing security too?" Dimitri: "I am security. This is my watch." Rose: "Well, good work. I'm glad I was able to help test your awesome skills." - Rose Hathaway and Dimitri Belikov (Shadow Kiss)
Yes, I think lots of people are eager to obtain weapons of mass destruction. But there's no evidence that he has weapons of mass destruction. There's been no evidence of him testing nuclear weapons.
We have people that are in our face with nuclear weapons. We've got Iran and North Korea. We've got a problem with Pakistan. You know, I don't know what to say about that.
There's a whole lot of people that are going nuclear. And I think that Saddam Hussein is actually, with the evidence, the least able to use nuclear weapons and the least obvious offender in that area at this moment.
I believe without exception that theory follows practice. Whenever there is a conflict between theory and practice, theory is wrong. As far as I'm concerned, we make theories for what people have done.
