What will he doodle in either a square or cube?
Mmm, a skating rink is more oval. But I’d skate on a round one. Might keep the hockey players away.
I don’t see your angle here
just seeing the word ‘tubular’ got me thinking about Mike Oldfield’s classic seventies album
here is the whole enchilada
Geometry lesson from Thatababy!
tubular makes sense for surfers since they can be inside a huge tube of water. not so much on the outside.
Dr Pedanto, here.
A trapeze would be more appropriate with a trapezoid (a quadrilateral with two parallel sides), being from the Greek word for “table”, τράπεζα (trápeza) literally “having three feet”: archaic Greek tables were quadrilateral but narrower at the single-leg end, for stability.
And why three feet? A piece of furniture with three feet, e.g. a stool, is stable on any irregular surface, since any three points define a plane and three points are therefore automatically always in the same plane.
And why are trapezes so called? Because for (vitally necessary) stability, the anchors are a bit farther apart than the length of the bar.
Etymology is so cool. (Discussion of how you get “three” from Greek τρα- is for another time.)
