A Dyson Sphere is a megastructure that could be built around a star to harness all the solar energy it gives off. In this video we talk about the different kinds of Dyson Spheres, Dyson Clouds and other megastructures that could be built - and how we might even detect them from Earth. ht

Conrad Plaut (5/10/22), Discrete Homotopy Theory and Applications
Discrete homotopy theory was originally developed by Valera Berestovskii and Plaut in 2001 as an effort to understand generalized covering spaces of topological groups. Over the last couple of decades the ideas evolved to include uniform spaces and hence metric spaces. The basic idea is to

Lecture 7: Sheaves of sets (Part 2)
The most important examples of topoi are categories of sheaves of sets on a small category. Patrick Eilliott introduced this class of examples over two talks, of which is the second. In this talk he defines Grothendieck topologies and the category of sheaves on a site, and develops the exa
