Perhaps this is related to the more theoretical nature of math and physics? With computer programming especially, you can immediately apply the concepts you learn and get instant feedback and satisfaction from seeing simple programs actually achieve things. With math and physics, I've found that I am far motivated to learn concepts when having an immediate practical application for them, say in the context of computer graphics. Being able to apply what you're learning to create things is tremendously motivating, while if you remain in the pure theoretical domain, it can seem abstract and aimless without an external structure to direct you.
