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 ...

Harvard physicist Avi Loeb adds a 14th anomaly, highlighting the rare 8-degree sunward alignment of 3I/ATLAS’s anti-tail jet ...

Mountain bike geometry has taken significant leaps and bounds in the last few years, with long, slack, low figures – referring to wheelbase and reach, head tube angle, and bottom bracket height ...

A road bike frame is essentially three big tubes stuck together in a triangle, four thinner ones to support the rear wheel and a fork to hold the front wheel and allow it to turn. But it’s a lot more ...

Interior angles in a triangle add up to 180˚. Triangles close triangleA polygon with three straight sides. have three sides, therefore they have three angles. Interior angles in a triangle sum to a ...
