Exactly this video made me read more into this topic, I'm currently reading winning ways and lessons in play simultaneously. It's quite fun! I've just gotten started and am looking forward for what's left.

Thanks for sharing this. I just discovered it now and I love it too.

The space of possible abstractions for any given phenomenon is vast, yet we almost always just assume that real numbers will do the trick and then begrudgingly allow complex ones when that doesn't work. If we're not lucky we end up with the wrong tool for the job, and we haven't equipped people to continue the exploration. It's a bias with some pretty serious consequences (thanks... Newton?).

I don't think I've seen the inadequacy of number-systems-you've-heard-of demonstrated so clearly as it is done here.
