Ive heard that at least a couple of the impossible compass/s.e. constructions ARE possible when paper folding is allowed (i.e.:origami folds). I wonder what the field extensions of all possible origami folds would be?...and how do we go from those more abstract extensions to ~dirty ~reality ? (E.g.: you introduce minute deformations since the paper isnt perfectly flat/can only be folded in half ¿7? times/etc)
Love these lectures!!!
good job!
Great work! Hope you continue doing the same in future.
42:31 If x^2 is rational, then we don't need it in the basis anyway so can't we skip this step?
Well done. Very clear.
Thanks a lot professor
