Truncation (geometry)
In geometry, a truncation is an operation in any dimension that cuts polytope vertices, creating a new facet in place of each vertex. The term originates from Kepler's names for the Archimedean solids. (Wikipedia).

Trigonometry - Vocabulary of trigonometric functions
In this video will cover some of the basic vocabulary that you'll hear when working with trigonometric functions. Specifically we'll cover what is trigonometry, angles, and defining the trigonometric functions as ratios of sides. You'll hear these terms again as we dig deeper into the st

Lisa Glaser: A picture of a spectral triple
Talk at the conference "Noncommutative geometry meets topological recursion", August 2021, University of Münster. Abstract: A compact manifold can be described through a spectral triple, consisting of a Hilbert space H, an algebra of functions A and a Dirac operator D. But what if we are g

Carlo Rovelli: The essential role of coherent states in quantum gravity
Abstract: Conventional quantum field theory techniques do not work for extracting physical information from a background-independent quantum theory of gravity. A technique that works is Oeckl's boundary formalism, with semiclassical coherent states on the boundary. I illustrate how this te

In this video we explore how the general relations Log and Exp between a point z on a central conic, and the signed area of the sector formed by that point z and a fixed point 1 on the conic are related, particularly in the green geometry. This general format allows us a larger view of the

Trigonometry - Solving a right triangle
Trigonometry is all about the study of right triangles. We can use the many different functions and connections in a right triangle to find missing sides. I'll cover two of those examples in this video. One where we will know an angle and a side, and another where we have two sides. Ta
