302.8B: Quaternions and Classifying Rings

[@192ali1]

To click on "Thombs Up" in order to indicate your acknowledgement of your satisfaction about the lecture in this and other videos of Dr. Salomone is like giving a drop for the ocean of satisfaction that he deserves. I wish there was no limit of clicking on that "Thombs Up" icon so that I could click on it 10 ^ 23, Avogadro's number of times. Thank you Matthew.

Quaternions? More like "Quite interesting lectures to think upon!" 👍

Great videos, very helpful!

[@westronic]

Super helpful, thank you!

When calculating the multiplicative inverse of a+bi+cj+dk like that, the coefficients of 1, i, j and k in the inverse won't be integers. But we're looking at Z[i,j,k]. So I can't see that this ring has multiplicative inverses. What have I missed? (It would be fine in Q[i,j,k].)

2:15 We are considering R[i,j,k] not Z[i,j,k].

@@Abhyaskul Out of curiosity, how have you been doing over this almost-decade?

[@Abhyaskul]

at that time i was in graduation and learning modern algebra. now i have done doctorate and teaching graduation subjects (and learning too).

[@PunmasterSTP]

@@Abhyaskul Oh awesome; I'm really glad to hear that! Is abstract algebra one of the things you teach?

[@bonbonpony]

This Venn diagram is a MESS! ;q

[@westronic]

It's accurate though, just a lot of info to present.
