Make a hyperbolic paraboloid of sticks

The beautiful “hyperbolic paraboloid“ fascinates mathematicians and has inspired architects and engineers. Get a feel for the structure with this stick and rubber band model. Used wooden dowel rods attached with tiny rubber bands (hair elastics). Mathematicians are interested in the hyperbolic paraboloid for several reasons. It has a “saddle surface“ with a “doubly ruled surface“ meaning you can line up straight sticks across one edge to another and also line up straight sticks across in the perpendicular direction and they all lie on this surface. As in any ruled surface, a line can be drawn through any point and the entire line stays on the surface. A few famous buildings use this design in their roofs. Such architecture distributes stress evenly and has an elegant appearance. #paraboloid #paraboloidehiperbólico #hyperbolicparaboloid #beautifuldiscoverymodeling #artforfun #artforkids #stickart #geometry #woodsculpture #stem #steameducation #stemeducation #homeschooling
