Michio Kaku Quotes

It is not observation but theory that led me to this result that experience has confirmed afterwards.

Science makes no pretension to eternal truth or absolute truth.

A good scientific theory is one which is falsifiable, which has not been falsified.

Facts are not science - as the dictionary is not literature.

We don't regard any scientific theory as the absolute truth.

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.

I really do think that science has an internal structure, and it makes sense, and we can test it.

It is also a good rule not to put overmuch confidence in the observational results that are put forward until they are confirmed by theory.

Science is not, despite how it is often portrayed, about absolute truths. It is about developing an understanding of the world, making predictions, and then testing these predictions.

The work of science is to substitute facts for appearances, and demonstrations for impressions.

You can't prove any hypothesis, you can only improve or disprove it.

In science, you can say things that seem crazy, but in the long run, they can turn out to be right. We can get really good evidence, and in the end, the community will come around.

As a scientist, I don't believe anything. Science shouldn't use the word belief. There are things more likely and less likely. Science can say nothing with absolute certainty.

Science is uncertain.

Truth in science can be defined as the working hypothesis best suited to open the way to the next better one.

Everything that people say is testable.

Where we have good, testable explanations, they then have to be tested, and we drop the ones that fail the tests.

Facts are the air of scientists. Without them you can never fly.

I can assure you that no string theorist would be interested in working on string theory if it were somehow permanently beyond testability. That would no longer be doing science.

The true method of knowledge is experiment.

Truth in science is always determined from observational facts.

The strongest arguments prove nothing so long as the conclusions are not verified by experience. Experimental science is the queen of sciences and the goal of all speculation.

If anyone offers conjectures about the truth of things from the mere possibility of hypotheses, I do not see by what stipulation anything certain can be determined in any science, since one or another set of hypotheses may always be devised which will appear to supply new difficulties.

You make observations, write theories to fit them, try experiments to disprove the theories and, if you can't, you've got something.

It is a test of true theories not only to account for but to predict phenomena.
