Intrinsic Geometry

Today I wanted to discuss the geometry of curves and surfaces.

Curves, Curvature and Normals

First let us consider a curve r(s) which is parameterised by s, the arc length. 315 more words


Did you know that there’s no such thing as “outer space”?


This meme below inspired me to make this post. There is no such thing as the “outer space” that we have been conditioned to believe in by charlatans who claim to be scientists. 223 more words
