   Error correcting codes are one of the coolest things you can do with math. In general learning math is important for the knowledge buzz moments and the general "tooling for thought" but all of these are a little abstract and har

    This is really well done. I signed up and used the sample code provided to set up on my site. Founders were super helpful and gave me a few pointers when I ran into problems (my version of react was old). It works great.

    What do we need topology for? Is it for GR? And same for abstract algebra? is this about the symmetries in high-energy physics? I agree with you in general that one needs to learn serious math to advance in physics, but it's always exc
