This is a pre-talk for the Algebra Seminar on Oct. 24. I will discuss (various) definitions of matroids, matroid minors, Tutte polynomials and characteristic polynomials, matroid basis polytopes, and Grassmannians. If time permits, I'll also discuss permutohedral varieties and the Cremona map and/or my current work.
