Geometry · Independent research

I’m working through Delone and Zhitomirsky’s geometry problems, recording solutions, geometric interpretations and open questions along the way.

New paper: Flat models of systems with connection · Russian preprint

GIGI Builds

Geometric data systems · Hands-on learning

I use GIGI Builds as a companion to Davis Geometric Summer Camp. Through chapter-by-chapter builds, exercises and interactive demonstrations, we explore how a database can represent the shape and connections of its data.

The site also accompanies my GIGI Builds book, with a path from the structure of a record to the engine, geometric signals and distributed systems.

Flight control · Mach Industries

The flight-control blog grew from studies, correspondence and interactive experiments into The Geometry of Flight. The original entries remain available here; the blog is no longer active.
