Then you realize it was this guy: https://en.wikipedia.org/wiki/Erik_Demaine
So, still a great result, but not as out there as one may think.
I think it's also worth pointing out that in theoretical CS and most of math, it is common to list authors alphabetically. I don't think we have a way of knowing the relative contribution of the two authors. Demaine is obviously accomplished, but I find the kind of hero worship found in this thread distasteful and the facts don't support it here. Give credit to Langerman; Demaine surely would!
His lectures are absolute gold. He explains everything so clearly, simply, and efficiently.
I started skipping lectures in favor of watching his videos, and it saved me countless of hours -- and I got a perfect mark :)
I understand the idea behind that phrasing but I'm not sure I agree with it. Are you no longer a child prodigy once you turn 18? I don't think I'd ever say "former intelligent child".. Would I?
Very challenging to word in a succinct manner.
Maybe "a child prodigy in his youth" would be both precise and succinct enough, but at the same time language is for humans and I feel humans know what is meant by former child prodigy.
One interesting question from audience was whether the ratio between the largest polygon piece and the smallest piece can be made bounded, as the current construction has unbounded ratio.
