I'm a high-school graduate, on my way to college this September. I have this problem. I like mathematics and physics a lot, and, at least up to high-school level I've been getting good grades in it (I won the Cambridge Outstanding Learner's Award for topping A-Level Physics in my region). In mathematical terms, I think I comprehended most of the stuff in my Physics curriculum. Lots of people say that one can understand things better if one visualizes them in the mind. However, I feel that I lack the imagination (or am not intelligent enough) to visualize or better understand some of the concepts in Physics. For example, the Kinetic model of matter which was taught in my freshman year, was easy to understand for me as I imagined tiny little spheres randomly jiggling around. The Rutherford model wasn't that difficult either. I believe I comprehended electron shells and sub-shells too. But I got stuck at orbitals. I understood the concept at face-value and was able to answer questions about it but I just couldn't visualize it. The same thing happened for the concept of light being quantised. Once again I understood the equations perfectly (I think) but couldn't visualize the process. I understand pretty much most other subjects such as Biology etc. via visualization and this worked in Physics for about the first two years in high-school, but after that the concepts became difficult to visualize. Firstly, is there any way to visualize concepts like the ones I mentioned? Are there concepts in Physics that cannot be visualized at all? Can this difficulty prove to be a setback for me later in my Physics career?
