Richard Fitzpatrick's free e-book A Modern Almagest: An Updated Version of Ptolemy’s Model of the Solar System presents a modernized version of Ptolemy's Almagest. (I mention it here.)

Before we go too far ... the wavelength of visible light is about half a micron. If you do succeed in setting up standing waves, and figure out how to visualize it, you won't be able to see the wave pattern themselves. The wavelength is too small. You might be able to visualize the increased intensity in the cavity, though. I've seen that in plastic ...

Good question. When we build a theory we start from a couple of assumptions that we BELIEVE that are valid, i.e. in the everyday life, and/or in previous experiments, they were confirmed. From this point we use mathematics and obtain other results. As long as we need our new results for proving even more theorems, things may be fine. But a physical theory is ...

Newton described his theories with maths, and they worked great, until Einstein came along and found that as objects approached the speed of light, Newwton's maths broke down. Empirical evidences trumps theory.

Check out Richard Feynman's QED lectures. It's not quantum gravity yet but it might be what you're after.

First, caveat -- I am still in the learning phases of QFT. Math skills used and needed: Linear Algebra, vectors in Hilbert Space, Hamiltonians, Lagrangians (just like regular QM). Tensor notation, 4-vectors, special relativity, metric tensors at times. Feynman Path Integrals. Calculus of Variations. Fourier Analysis. And, certainly this list is not ...

I believe that particle physics is a field where to be able to contribute to the field you must have the mathematics. Without them your understanding will be severely limited and in many cases not even wrong. On the other hand it is possible to contribute to physics to in general with no more math than you get in junior high. This is because physics is the ...
