I often wonder what would happen if we learned high school concepts like geometry by recreating concepts like this - maybe alongside learning the proofs, or even before.<p>Being able to derive proofs on tests is important, but I think equally important is to have created knowledge you can reference in the future.

This is neat. I’m actually in a Computational Geometry course this semester. Computational Geometry is pretty neat stuff and has some cool applications. Like for example mixing 3 paints to get certain ratios can be reduced to a convex hull problem where all the possible paint color ratios are contained in the triangle with the 3 points (representing the ratio of the colors of the paints) as vertices. My course doesn’t involve any coding and is more about algorithm design through pseudo code and proofs.

Very interesting. I like the examples.

i _remember_ submitting this earlier, and sure enough : <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=13800862" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=13800862</a><p>but this was a while back :), so not marking it dupe.
