don’t get fixed in proving the constructibility of enormously large polygons
Is this common? ’Cause um, at one point I did try to prove (or disprove) the constructibility of a hendecagon (11 sides) with neusis, but I didn’t realise this was a popular pursuit. This isn’t really related to the post, but I was very surprised constructibility got a mention.
(I ran into equations lacking an easy solution—they were sufficiently long/hard that Maple refused to chug through them—and decided it wasn’t worth the effort to keep trying.)
I forget what it was called, but I remember a past post about trying to disprove very, very settled rules of math or science. A lot of the people who commented on it said that they had tried to do this as teenagers. (I never tried to construct unconstructable shapes, but I tried for a couple weeks to design a perpetual motion machine, once. I stopped after my middle school science teacher explained why a certain design wouldn’t work—the explanation was what I needed to finally grok the laws of thermodynamics.)
When I was very young—I think thirteen or maybe fourteen—I thought I had found a disproof of Cantor’s Diagonal Argument, a famous theorem which demonstrates that the real numbers outnumber the rational numbers. Ah, the dreams of fame and glory that danced in my head!
Hm, that’s true, I have heard that. Although in that particular case, it’s actually unknown whether the shape is constructible or not, and I was trying to prove (in)constructibility rather than construct.
