(don't) trust me bro!¶
Formulas derived from scratch. No magic, just logic.
Because understanding why is better than memorizing what.

Why this wiki?
Textbooks tell you what the formula is. Professors show you how to use it. But too often, the response to "Why?" is essentially "Trust me, it works."
We believe that understanding > memorizing. When you can see the logical path from basic principles to the final result, you don't need to trust anyone. You own that knowledge.
