And the actual achievements of biology are explanations in terms of mechanisms founded on physics and chemistry, which is not the same thing as explanations in terms of physics and chemistry.

But honestly, if you do a rigorous survey of my work, I'll bet you'll find that biology is a theme far more often than physical science.

But a science is exact to the extent that its method measures up to and is adequate to its object.

To me, what makes physics physics is that experiment is intimately connected to theory. It's one whole.

Throwing more science at things isn't always the answer.

Science is simply common sense at its best, that is, rigidly accurate in observation, and merciless to fallacy in logic.

My background is basically scientific math. My Dad was a physicist, so I have it in my blood somewhere. Scientific method is very important to me. I think anything that contradicts it is probably not true.

We tend to think of science as finding equations, like E=MC2, that are simple and elegant. But maybe some theories are complicated, and we can only find the simple ones.

I believe all complicated phenomena can be explained by simpler scientific principles.

It is wrong to think that the task of physics is to find out how Nature is. Physics concerns what we say about Nature.
