#### The depth of a mysterious Pyramid

The music of the heavens was believed to be describable through numbers and geometry with a system of codes originating from the fundamental structure of space-time. 458 more words

#### Straight lines in elliptic and hyperbolic space

A straight line is the shortest path between two points. Discussing curved space we would better call them geodesic lines to avoid confusion. I want to discuss these geodesic lines for surfaces of a sphere, elliptic space and hyperbolic space. 605 more words

#### Life on the PoincarĂ© Disk

2,230 more wordsJust at this time I left Caen, where I was then living, to go on a geological excursion under the auspices of the school of mines.

#### How to program fast kaleidoscopes

This post repeats parts of earlier postsÂ but I am trying to expand the ideas and explain them better. First, I am showing you how to make rosettes with rotational symmetry and mirror symmetry. 1,936 more words
