Imagine I generate some polyomino (http://en.wikipedia.org/wiki/Polyomino) with $N$ unit squares, under the constraint that I want to maximize the number of shared edges between unit squares, or ...
Frustrating the number of possible common edges between two connected components composed of square Penrose tiles
Imagine I have two bags of square and planar unit square tiles, with Penrose-like "nodules" on their edges s.t. two tiles can only be placed together if their edges are flush (i.e. if the two vertices ...
Let $\cal C = \lbrace C_i \rbrace$ be a collection of rectifiable curves in the plane with the property that every unit-length segment meets at least one curve in at least one point. Call such a ...
I was looking at this neat page on logarithmic spiral tilings when a question popped up: http://www.uwgb.edu/dutchs/symmetry/log-spir.htm It seems that in all of the tilings shown, the area of each ...
