An easier way to show that a subset of a group is a subgroup: just check closure and inverses.

Professor Learnifyable: Thank you so much for updating the video on the Subgroup Test. Can you recommend any student-friendly textbooks on abstract algebra? I wish the authors of most existing abstract algebra books could explain concepts as well as you do! Are you now teaching at a university or college? If so, which one? You are a wonderful communicator of advanced math, and I look forward to seeing future videos on cyclic groups, symmetric groups, permutation groups, cosets, etc. Many thanks again for producing the videos; I know it takes a lot of work. > Benny Lo California February 26, 2014

Most undergraduate abstract algebra courses use "A First Course in Abstract Algebra" by John B. Fraleigh, but I prefer "A Book of Abstract Algebra" by Charles C. Pinter. It's a Dover book, so it's cheap, and it has really great explanations. I am not currently teaching. My background is actually in mathematical physics, so you might see some more physics videos in the future... Thanks again for the kind comments.

@@learnifyable Can you make one on the Dirac hole theory, holographic principle, Kaluza Klein theory, differential manifolds, Schwarzschild metric, Raychaudhuri equation or Yang Mills existence?

Don't forget about Levi Civita symbols and Christoffel coefficients!
