About Physics Etc.

Our Mission

Physics Etc is dedicated to demystifying the mathematical foundations of physics for students, enthusiasts, and lifelong learners. While many resources offer high-level overviews or deep academic research, there is often a gap in explaining how the math actually works to describe physical laws. This site aims to fill that gap by breaking down classic derivations and concepts into accessible, step-by-step articles.

About the Author

This site is curated by me, Gabe, a former Physics Teaching Fellow with a good background in math and physics. Due to a disability, I now work primarily from home, where I focus on self-directed study and things I can do on my computer.

During my time teaching undergraduates, I often found that while students understood the concepts conceptually, the barrier to entry was frequently the specific mathematical techniques used in derivations. I created Physics Etc. to be the resource I wish I could have pointed my students to—a place where the "language" of physics is taught alongside the physics itself.

Whether you are a student struggling with your first calculus-based physics course, or a hobbyist wanting to understand why the wave equation is so significant to Relativity, this site is designed for you.
