I remember reading a review for Landau and Lifshitz’s “Mechanics”book where they came away in tears from the beauty within those pages. It’s haunted me ever since because when I bought it and cracked it open, the maths was so incomprehensible that i refused it pick it up again…

But last week after reading a blog post on quaternions, it finally clicked! Most of the really scary looking maths in higher physics was nothing more than a little bit of Abstract and Linear Algebra, a bit of Calculus, and a lot of coffee!

When you see people talking about “The Standard Model”, it turns out it’s nothing scary at all - it’s just a way of expressing a physical system using Gauge Theory, which is nothing more than Lie Algebra (Abstract Algebra) under Lagrangian Mechanics (Linear Algebra and Calculus)

After I made this revelation, I wanted it confirmed I was sort of right (I’m probably still technically way off), but one person said yep, and then told me to get a copy of Physics From Symmetry by Jakob Schwichtenberg
