Hello everyone, I'm a math and philosophy double major currently in my junior year at University. So far, I've spent the better half of two years studying philosophy and have five credits to go before I complete the major (focused primarily on philosophy of science, and epistemology). This quarter I declared a major in mathematics with a Bachelor of Arts options and have completed the calculus sequence, and am a few weeks shy of competing linear algebra. I'm intending to take differential equations next quarter, and intro to proofs along with intermediate macroeconomics. After real analysis I plan on focusing my electives in statistics, and numerical analysis, and have been studying C++ out of the C++ primer for several months now to hone my computer knowledge and have a basic enough understanding to make simple calculators, use strings, and loops. Since I was a kid, I've had a deep interested in space sciences, and remember watching the first commercial space rocket launch by Space X, and feeling in awe concerning the entire thing. The issue is that I've taken chemistry 142 (first class in the freshman chem sequence), and Physics 121 (freshman calc based physics), and I didn't due to well due to my immaturity at the time (skipping classes and such), along with working as a pizza delivery driver 25-32 hours a week, but still managed to pass although not with the best grades. I know this is nothing to look highly upon, but since then I've been studying "University Physics" by Young and Freedman by doing example problems and the problems at the end each chapter when I'm at work, or have completed my other homework. I'm good at keeping myself focused my learning goals when I self-study, and make attempts to derive whatever's handed to me. I really want to work in the field of astronautics or propulsion design someday, but I understand that math isn't as technically oriented as other majors such as engineering. Is there a way to get the appropriate knowledge through books on the topics? I won't be discouraged by difficulty and understand it might take a while. I've never really been a fan of light reading, and I have an unquenchable thirst for new knowledge.
