Lorentz surface

In mathematics, a Lorentz surface is a two-dimensional oriented smooth manifold with a conformal equivalence class of Lorentzian metrics. It is the analogue of a Riemann surface in indefinite signature. (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.

Learn how to determine the volume of a sphere

👉 Learn how to find the volume and the surface area of a sphere. A sphere is a perfectly round 3-dimensional object. It is an object with the shape of a round ball. The distance from the center of a sphere to any point on its surface is called the radius of the sphere. A sphere has a unifo

Riemann Roch for genus 0 curves

This lecture is about the Riemann_Roch theorem in the case of genus 0 curves. This is an easy warming up exercise for the harder cases of nonzero genus as we can work everything out explicitly. We verify the Riemann-Roch theorem for the projective line (or Riemann sphere), and then use the

The Emergence of Kinetic Energy #SoME2

**There is an error in the Energy & wavelengths chapter. The formulas of Lambda_1 and Lambda_2 should be: Lambda_1 = Lambda_rest * ( ( c + v) / c ) Lambda_2 = Lambda_rest * ( ( c - v) / c ) Sorry for the error.** This is an attempt to explain the properties of kinetic energy through oth
