We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
"Bridge of asses." Donkeys do not like to cross bridges.
In mathematics, the term is applied to the problem from the first book of Euclid that if two sides of a triangle are equal then the angles opposite those sides are also equal.
Traditionally, the bridge of asses referred to Euclid's Fifth Theorem of planar geometry, the comprehension of which and the implications of which were and are a sticking point for less-bright students.
By the way, this is a good if somewhat challenging book: Experiencing Geometry. A bit of a pons asinorum itself.
