Lawrence M. Krauss Quotes

Science is simply a powerful way of understanding what's real and what isn't, what's true and what's not. It can help us determine what works, what doesn't, for whom, and under what circumstances.

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

Science is a self-correcting discipline that can, in subsequent generations, show that previous ideas were not correct.

Scientists are always skeptics.

A valid scientific theory is predictive, verifiable, and replicable. To me, that's beautiful.

Of course, not everybody's willing to go out and do the experiments, but for the people who are willing to go out and do that, - if the experiments don't work, then it means it's not science.

Science isn't about authority or white coats; it's about following a method. That method is built on core principles: precision and transparency; being clear about your methods; being honest about your results; and drawing a clear line between the results, on the one hand, and your judgment calls about how those results support a hypothesis.

In science, we must be interested in things, not in persons.

Traditional scientific method has always been at the very best, 20 - 20 hindsight. It's good for seeing where you've been. It's good for testing the truth of what you think you know, but it can't tell you where you ought to go.

Science is a wonderful way of getting out what's real.

Something my father dearly loved is the scientific method, and it's founded in this element of humility. The idea is that you pursue the truth wherever it goes; you need to evidence, and you can - you see if it's repeatable.

Educated guesswork' is what science is. You form hypotheses, test them against the evidence, and if they fit the evidence, you can assume you've got close to the truth.

Every theory presented as a scientific concept is just that; it's a theory that tries to explain more about the world than previous theories have done. It is open to being challenged and to being proven incorrect.

Science does not limit itself merely to what is currently verifiable. But it is interested in questions that are potentially verifiable (or, rather, falsifiable).

Reason, observation, and experience; the holy trinity of science.

I had learned that science is a rewarding, active process of discovery, not the passive absorption of what others had discovered.

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

Science by itself is about numbers, and it's about measuring things. It's very important but it's very dry.

I love to watch how scientists' minds work.

Science, my lad, is made up of mistakes, but they are mistakes which it is useful to make, because they lead little by little to the truth.
