    Very useful video series on abstract algebra. Do you plan to continue this series? For example, some module theory?

    Same here. It's like they are super-structured.

    thank you Dr.Bob.
    Can you help me in making algebriac topology curriculum?

    Why is Gal(K/Q) ~ Z/2 x Z/2 and not to C_4 ~ Z/4 is not explained, though I guess it was previously check or explained...

      +Jose A. Perez Since K=Q[sqrt(2), i], all automorphisms are generated by conjugations sqrt(2) -> -sqrt(2) and i -> -i. So all automorphisms have order 2 (no element of order 4).
