There are some good websites and videos that review things like ancient and Middle Ages physics or windmills and capstans and pulleys and rope and knot technology that will amaze you. I love digging into things like this too.
Modern science is a wonderful thing, but the arrogance of many of the so-called experts hinders true scientific research. the Pyramids are a great example of this, after decades of research no one has come up with a solution to how they were built.
