Star Systems and Types of Galaxies

We've learned a lot about stars! We know how they form, and we know that most of them exist in galaxies. But how are they arranged within galaxies? And are there different types of galaxies or are they all the same? There is a lot to discuss here, so let's expand our understanding of star

Spectroscopy - Splitting the Starlight

How do we know what stars are made of? Starlight contains millions of fingerprints - spectral lines, which are produced by chemical compounds in the form of molecules, atoms, which are present in the atmospheres of stars and planets. The films shows how scientists decode stellar light and

Introduction to additive combinatorics lecture 7.9 --- Basic Fourier transform properties

Here I say a bit more about the discrete Fourier transform, including giving direct proofs of the basic properties that are used over and over again in arguments. As an example of how it relates to additive combinatorics, I show that the additive energy of a set can be expressed in a very

http://www.teachastronomy.com/ The Stephan-Boltzmann Law allows us to understand the state of stars with the same spectral type as the Sun but with very different luminosities. In this case the scaling reduces to radius going as the square root of luminosity. There are stars the same col

Building a star from bits and bytes

How large is the Sun, how hot and how old is it? Much of what we know about stars comes from the models built upon fundamental laws of physics. Building stars in the terrestrial laboratories is impossible, buiding stars in a computer is. But computer models allow us to “see” below the surf

S. Hersonsky - Electrical Networks and Stephenson's Conjecture

The Riemann Mapping Theorem asserts that any simply connected planar domain which is not the whole of it, can be mapped by a conformal homeomorphism onto the open unit disk. After normalization, this map is unique and is called the Riemann mapping. In the 90's, Ken Stephenson, motivated by

What is a star graph in graph theory? We go over star graphs in today's lesson! Star graphs are special types of trees. Any graph with n vertices, where 1 vertex has degree n - 1 and any other vertex has degree 1, is a star graph. The star graph of order n is isomorphic to the complete bip
