Clebsch surface

In mathematics, the Clebsch diagonal cubic surface, or Klein's icosahedral cubic surface, is a non-singular cubic surface, studied by and , all of whose 27 exceptional linescan be defined over the real numbers. The term Klein's icosahedral surface can refer to either this surface or its blowup at the 10 Eckardt points. (Wikipedia).

MATH331: Riemann Surfaces - part 1

We define what a Riemann Surface is. We show that PP^1 is a Riemann surface an then interpret our crazy looking conditions from a previous video about "holomorphicity at infinity" as coming from the definition of a Riemann Surface.

Clebsch–Gordan Coefficients Explained

In this video, we will talk about Clebsch-Gordan coefficients. We'll discuss their definition, and explain how to use them. Clebsch-Gordan coefficients are named after the German mathematicians Alfred Clebsch and Paul Gordan. The coefficients are defined like this: Clebsch-Gordan coeffici

An introduction to surfaces | Differential Geometry 21 | NJ Wildberger

We introduce surfaces, which are the main objects of interest in differential geometry. After a brief introduction, we mention the key notion of orientability, and then discuss the division in the subject between algebraic surfaces and parametrized surfaces. It is very important to have a

Condon-Shortley Phase Convention | Clebsch-Gordan Gets Real

In this video, we will explain the Condon-Shortley phase convention. This is a widely used set of two statements, which together lead to the conclusion that all Clebsch-Gordan coefficients are purely real numbers. It's named after the US physicists Edward Condon and George Shortley, who in

Deriving Clebsch–Gordan Coefficients | Angular Momentum in Quantum Mechanics

In this video, we will show you how to explicitly calculate the Clebsch-Gordan coefficients for the simple case of two spin-1/2 particles. Note, that this is purely for fun, or educational purposes, since for a real calculation, you should always look up the relevant coefficient in a table

Evaluating Surface Integrals

Surface integrals are kind of like higher-dimensional line integrals, it's just that instead of integrating over a curve C, we are integrating over a surface S. This can be tricky, but it has lots of applications, so let's learn how to do these things! Script by Howard Whittle Watch the
