 The Fano Plane

by Ed Pegg Jr.,
May 30, 2006:

“One thing in the Fano plane that bothered me for years (for years, I say) is that it had a circle – and it was described as a line. For me, a line was a straight line, and I didn’t trust curved or wriggly lines. This distrust kept me away from understanding projective planes, designs, and finite geometries for a awhile (for years).”

“Against stupidity
 the gods themselves
 fight unvictorious.”

 — Schiller,* quoted as
the epigraph to the
chapter on Galois in
Men of Mathematics,
by E. T. Bell
