Everyone learns the number one rule about triangles in high school: the angles of a triangle add up to 180 degrees. But did you know that sometimes they don't? Triangles are much more interesting than ...

One hypothesis about the shape of the universe is that the universe is in the space of Euclidean geometry and flat. In Euclidean geometry, it is assumed that straight lines extend everywhere, planes ...

Geometric patterns are classics in modern design speak. But one that especially resonates these days is the triangle. Specifically, triangles laid end to end to create mesmerizing larger-scale ...

Fallen Triangle can be a tricky yoga pose. Your legs turn away from your body in opposite directions. Your front hamstring is stretched beyond what may seem reasonable. Your core muscles--including ...

THE principal novelties in this tract are the chapters on the orthopole (with some original propositions by the author) and on orthogonal projection (mostly after Prof. Neuberg). A pretty theorem in ...

In our mind’s eye, the universe seems to go on forever. But using geometry we can explore a variety of three-dimensional shapes that offer alternatives to “ordinary” infinite space. When you gaze out ...

Anaïs, I don't know how to tell you what I feel. I live in perpetual expectancy. You come and the time slips away in a dream. It is only when you go that I realize completely your presence. And then ...
