I love art and math. M. C. Escher and Albrecht Dürer are strong influences. I'm also interested in space exploration.

Matrices
I enjoy linear algebra. I use it in making polyhedra and drawings. Here are a few visualizations of matrices. To keep it simple I use 2x2 matrices. 2x2 matrices act on vectors. The vertices of polygons in a plane can be described vectors, so these same tran...

So happy to see signs of life from the Rocketpunk blog. It's been dormant too long.

This talks about Asimov's Trantor, a huge megaopolis and capital of the galaxy from Asiimov's Foundation series. The post speculates about how huge a city could become.

Which prompted me to comment for smaller bodies the entire volume is accessible, not just the outer shell. Plus asteroid belts provide more surface area to radiate waste heat as well as more surface area to harvest energy from sunlight.

So it is my belief that the largest populations will inhabit rings of smaller bodies about a star. These archipelagos will host megapoleis that stretch the imagination.

In the comments Nyrath responded with a neat quote from Asimov's Strikebreaker. Seems Asimov was well aware of the advantages smaller bodies confer. In fact it was Isaac Asimov who coined the term "planetary chauvinism".

Lamentable Lagrange articles
Gravity doesn't cancel at the Lagrange points "There are places in the Solar System where the forces of gravity balance out perfectly. Places we can use to position satellites, space telescopes and even colonies to establish our exploration of the Solar Sys...

It is good to see a policy maker with a strong interest in space. I notice he imagines 10 billion rather than 600 million tonnes of lunar ice. I guess the error in Spudis' spreadsheet is acknowledged. Whether that much ice actually exists or not remains to be seen. At least with policy makers like Bridenstine we have a chance to find out.

General template for space elevators
A Family of Conic Sections Below is a general vertical space elevator. The conic sections are the paths payloads would follow if released from a point on the tether a distance r from body center. We choose our units so radius of the balance point is 1. The ...

Pluto Charon Elevator
Double Tidal Locking Pluto and Charon are mutually tidally locked. That is, they both present the same face to the other planet all the time. They hover motionless in each other's sky. Pluto is in Charon synchronous orbit and Charon is in Pluto synchronous ...
