Three-Dimensional Shapes Part 1: Types, Calculating Surface Area
Enough of this two-dimensional, stuck in one plane rubbish! The real world has three spatial dimensions! Technically more, but we very clearly interact with three all the time, so it's time to start talking about three-dimensional shapes like pyramids and prisms and cylinders and cones, an

What is a Quadrilateral? – Geometric Shapes – Geometry
Quadrilaterals all have four sides, but they all look a little different. How many kinds of quadrilaterals do you know? In this video we’ll talk about the different types of quadrilaterals. These geometric shapes include the square, rectangle, parallelogram, trapezoid and rhombus. Anot

Three-Dimensional Shapes Part 2: Calculating Volume
We introduced a number of three-dimensional shapes in the last clip, but we still just talked about two-dimensional surface area. What's up with that? Alright, alright, let's learn how to calculate the three-dimensional volume that a shape will occupy. This is like the amount of water that

Omer Bobrowski: Random Simplicial Complexes, Lecture I
A simplicial complex is a collection of vertices, edges, triangles, tetrahedra and higher dimensional simplexes glued together. In other words, it is a higher-dimensional generalization of a graph. In recent years there has been a growing effort in developing the theory of random simplicia
