Choose any direction and it will have a specific tangent—and the orthogonal direction will, too. From any point on a surface, there is a curve in each direction. A ball has two convex curves at any point; the inside of a sphere, two concave curves (Alberti 1436). At the top of a...

3D modeling starts with an artist generating a 3D primitive using numerous polygons such as a cube, cylinder, plane, or sphere. Then, the artist uses 3D modeling programs & tools to develop and refine the design into its new desired form. The 3D modeling workflow involves adding points in ...
The moon, like Earth, is a sphere, and it is always half-illuminated by the sun. As the moon travels around Earth, we see more or less of the illuminated half. Moon phases describe how much of the moon's disk is illuminated from our perspective. New moon: The moon is between Earth...

Some of you may have seen in school that the surface area of a sphere is 4πR24πR2, a suspiciously suggestive formula given that it’s a clean multiple of πR2πR2, the area of a circle with the same radius. But have you ever wondered why is this true? And I don’t just ...
