This site is a hidden gem on the internet. This guy deserves a lot more credit. I think he&#x27;s doing something at the level of Khan Academy, but for seemingly simple concepts we all take for-granted.<p>An article I really enjoyed was his explanation of Quake&#x27;s inverse square root method: <a href="https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20150530232103&#x2F;http:&#x2F;&#x2F;betterexplained.com&#x2F;articles&#x2F;understanding-quakes-fast-inverse-square-root&#x2F;" rel="nofollow">https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20150530232103&#x2F;http:&#x2F;&#x2F;betterexpl...</a><p>What I also appreciate is that he admits when he doesn&#x27;t understand something and doesn&#x27;t pretend to give an incomplete, vague explanation and just straight up says he does&#x27;t fully get it (like why the specific &#x27;magic&#x27; number in the Quake algorithm). Thankfully he linked the original paper and I read up on it myself. But his initial explanation provided a solid background for the paper.
