Lorentz group

What is the Lorentz Transformation?

What is the Lorentz Transformation? It is a tool we use to relate the different experiences of different observers in special relativity. It is also one of the defining features of special relativity and what differentiates it from Galilean relativity. In this video, we will derive the Lor

Group Definition (expanded) - Abstract Algebra

The group is the most fundamental object you will study in abstract algebra. Groups generalize a wide variety of mathematical sets: the integers, symmetries of shapes, modular arithmetic, NxM matrices, and much more. After learning about groups in detail, you will then be ready to contin

Visit http://ilectureonline.com for more math and science lectures! In this video I will list how the Lorentz factor, gamma, changes as velocity moves from closer and closer to the speed of light (from 0.1c to 0.999999c). The Lorentz factor is a factor that is multiplied to time, mass, an

Relativity's key concept: Lorentz gamma

Einstein’s theory of special relativity is one of the most counterintuitive ideas in physics, for instance, moving clocks record time differently than stationary ones. Central to all of the equations of relativity is the Lorentz factor, also known as gamma. In this video, Fermilab’s Dr. D

Symmetric Groups (Abstract Algebra)

Symmetric groups are some of the most essential types of finite groups. A symmetric group is the group of permutations on a set. The group of permutations on a set of n-elements is denoted S_n. Symmetric groups capture the history of abstract algebra, provide a wide range of examples in

Groups and subgroups

Jacob explains the fundamental concepts in group theory of what groups and subgroups are, and highlights a few examples of groups you may already know. Abelian groups are named in honor of Niels Henrik Abel (https://en.wikipedia.org/wiki/Niels_Henrik_Abel), who pioneered the subject of

In this lecture, I introduce states describing any number of particles and define operators acting on these states. I argue that causality requires that the theory be written in terms of "observables," local Hermitian operators that commute at spacelike positions. This leads us to a theory
