Modern scientists know neither the universal laws of nature nor the nature of anything. Do you disagree?

 I dreamed last night about modern science and the universal law...

The laws of nature are about phenomena. They don't know anything about the things in themselves. The phenomena form all we know about reality, they might as well be existence-independent.

Hello, Soundary, you pose a really deep philosophical question.  You must be a very intelligent person. I recommend that you practice very much on careful choosing the wordings of your questions.  You will never get a satisfactory answer if you don't. There is a philosophical school of thought called The Skeptics. They would say that no one can know anything absolutely.  Read Ludwig Wittgenstein!  Modern science can build "models" that describe the observable behavior of much of the cosmos.  We can predict related outcomes using these models.  In that sense, "modern science can ascertain at least a portion of the universal laws of nature."  Look at <Plato.Stanford.com>!

I will have to concur that Soundary (AKA Physicalist) knows nothing of any value.  Until you learn to work a three-place algebraic equation, you will not be of any worth whatsoever.

On the face of your statement, I do disagree.  Obviously, from the advances made in scientific discovery, there is much that scientists do know of the universal laws of nature.  Not too much more than a century ago, electricity had not yet been widely developed and utilized, etc.  It may be true that scientists are not all knowing -- that is, not to have the "inside" understanding of God -- but to say that man is without understanding is not correct.
