    My Introduction

    I found this website to share all of my self-study notes from the past year in the form of a big book! None of the work is AI-generated, and mostly comes from YouTube, Wikipedia, college PDFs and other physics/math websites online like Wolfram MathWorld or or Physics LibreTexts. Now that I am...
