The Lie algebra course is finally starting on the second channel. Check it out!! As a reminder, all videos on the second channel are ad-free to reduce the friction for learning. This is possible because of support via patreon/youtube members.

Hey YouTube:

I just made an example video for my current abstract algebra students over on my second channel. I intentionally solve this problem in a straightforward way that a student finishing their first semester of abstract algebra may come up with. Also, at the end I pose another solution that I don't really know the details for. Go check it out and:

-- wish my students good luck on their final
-- post a sketch for my third method.

Hey YouTube:
A few days ago we posted a video on a certain determinant identity. This was listed as "Sylvester's Identity" but it has come to our attention that it is often misattributed as such and should be the Weinstein-Aronszajn identity. Anyway, check it out if you missed it:

Hey YouTube!

In May, we are planning on adjusting the video schedule as a test to see if it'll be better than the current schedule. The new schedule will see four videos released per week: Tuesday, Thursday, Saturday, and Sunday.

I will let you all know whether we will continue this schedule around the end of May.

Thank you for supporting the channel!
