As someone trained in and having conducted scientific research, I can tell you that in most engineering and physics programs, the students are not informed that nothing they are learning gives them one iota of insight or understanding of what the intrinsic nature is of what they are studying.

"Materialism" is a philosophy, not science. There is absolutely no scientific experiment that would be in the least bit affected if one had the philosophy of dualism, idealism, or any number of other philosophies. The word "physical" is confusing as often people take it to mean that which we touch around us.

But in fact, the EXPERIENCE of touching is one that can only occur within conscious experience. Whatever it is we are "touching" is not revealed to us by scientific experiment.

None of what I'm saying is meant to prove or disprove any view. Materialism may be true (I'm an atheist, for what it's worth - at least in the sense you appear to be) or not.

Science, properly understood is thoroughly agnostic with respect to the nature of reality, as it should be, as it has no capacity to make any pronouncements as to what is real.

This gives you leeway to explore for yourself, using reason as well as intuition, what the nature of Reality. If you are interested, there are many contemplative traditions which provide a far better means of exploration than empirical, quantitative science.
