In high school I absolutely hated Physics. The class was just all about memorizing formulas and stuff, and I thought I wasn't learning anything useful for real life. Yet now that I'm older I have re-discovered my passion for science and I'd like to give the subject another try. The Internet especially is a wonderful resource for me, as I can look for the explanations of the formulas (something my textbook doesn't always have). So far I've only delved into the basics (and I'm already having some problems lol). What really gets me nuts though is, for example, the fact that I can't understand how Newton came up with the Law of Universal Gravitation (mathematically speaking) or how Kepler discover his Third Law of Planetary Motion. I don't know if I'm too dumb to realize that by myself or if the approach of the textbooks is just stupid. I'm starting to feel the same I did in high-school; I'm somehow not getting the full picture. What I wanted to ask anyway was if the subject got more and more abstract and mathy in advanced topics. Is Introductory Physics a bit dogmatic at first (and you later find out more about why some formulas work, why they came up with this law..) or is it just a taste of what is to come? If it's the latter (as I'm supposing) then it's a shame. Because I'm really interested in science. But it's like there's so much information to process that I just can't make sense of it all.
