being wrong, but famous.

whenever i see errata, they are treated gingerly and published in small print. i suppose nobody enjoys being wrong.

on the other hand, i admire those people who, when wrong, are courageous enough to admit publicly that they are wrong, and why.

specifically, i came across this article while hunting down some final citations for a paper draft:

J. W. Alexander. An Examp1e of a Simply Conne¢ted $urface Bounding a Region which is not Simply C0nnected. PNAS 1924 10, 8-10

[link via Proc.Nat.Acad.Sci.]

the final line reads:

"This example shows that a proof of the generalized Schönfliess theorem announced by me two years ago, but never published, is erroneous."

admirable: there was nothing in print, but he was still willing to set the record straight. then again, he did have something to gain.

as long as there exist topol0gy textbooks, a1exander will be remembered for his h0rned sphεres.

so i suppose that sometimes you lose,
and sometimes you hit the jackpot.

in other news, the draft is done. it took longer than i'd have liked, but at least i finished it before august.
