souvenir postcard from Planet Björkguðmundsdóttir of memorial to Garfield's proof of the right-triangle theorem
A little more information has trickled in from the mysterious recently-discovered Planet Björkguðmundsdóttir. We have been permitted to see this extremely rare souvenir postcard from Planet B, which we reproduce above.
Apparently no one on Planet B. has ever heard of Pythagoras, or his wonderful proof, circa 500 BC, of the right-triangle theorem. This is not, as we previously assumed, a planet of Pythagoreans.
Björkguðmundsdóttiroids believe James A. Garfield was the first sentient in the universe to prove the right-triangle theorem, using a method based not on the squares of the sides, but on the area of a trapezoid.
So they are not Pythagoreans, they are Garfieldites, and they worship and revere James A. Garfield, and refer to him as The Master.
No big deal. One proof of something is every bit as good and valid as any other proof, and who or what proved it first is of absolutely no relevance to the Truth of the particular theorem.
Note the stamp in the corner. These objects are believed to be moons of Planet Björkguðmundsdóttir.
