Query: An improved bound for the optimal paper Moebius band   In this paper we show that a smoothly and locally isometrically embedded
Moebius band has aspect ratio at least $\sqrt 3-(1/26)$. (The actual bound, an
algebraic number that arises in an optimization problem, is a tiny bit better.)
Our bound improves significantly on the previous known lower bound of $\pi/2$.
