What is a Four-Vector? Is a Spinor a Four-Vector? | Special Relativity
In special relativity, we are dealing a lot with four-vectors, but what exactly is a four-vector? A four-vector is an object with four entries, which get transformed and changed in a very special way after we change our frame of reference. More precisely, a four-vector transforms like a (1

SCATTERPLOTS: Visualize Relationships Between Two Scale Variables (4-4)
Scatter Diagram (a.k.a. Scatterplot) is a graph used with correlation and regression. It summarizes the relationship between two quantitative variables. Trendline (a.k.a. Regression line) approximates the relationship between the two variables. A pair of scale variables, X and Y, are plott

Galois theory: Artin Schreier extensions
This lecture is part of an online graduate course on Galois theory. We describe the Galois extensions with Galois group cyclic of order p, where p is the characteristic of the field. We show that these are generated by the roots of Artin-Schreier polynomials. Minor correction: Srikanth
