I have studied only theories for about two years now. The more I learn, the deeper my curiosity grows. Our universe is mind blowing, and I find it very fascinating. I've only learned from visualizations of what has already been discovered. I want to educate myself on solving the equations. However, even the most basic equations fluster me, and it is very frustrating. I need somewhere to start properly. Are there any recommendations of what I can study that will break down and elaborate equations that I can learn from? I want to understand the mathematics behind our universe. Any help on where to begin would be appreciated.
