Hi, all. Just repeating what I posted under my last video:

I'm glad that people have been appreciating the April Fools' videos I've made over the last few years, but moving forward, I can't promise I'm going to continue making them. I've been feeling less motivated to make them lately, and it's starting to feel less like a fun thing I enjoy doing and more like a chore that I need to uphold for the sake of tradition. I'd rather focus on making the videos I actually want to make. Sometimes that will include joke videos, but I'd rather make those naturally instead of being on a schedule. 

Next Spinors video should be posted on Saturday. It will be on tensor product representations of su(2). 

Hi all. I'm going to have to take back my previous post and say the Spinor for Beginners #18 won't be uploaded today.  I caught a few mistakes late last night that need fixing. I'll upload it later this week! 

Hoping to release the next spinors video tomorrow (Sunday). I'll be covering irreducible representations of SU(2) and the ladder operators. 

I was sad to learn today that professor Alex Flournoy passed away in late 2023:  https://news.snbc13.com/alex-flournoy-colorado-professor-died-after-battling-brain-cancer/ 

He was a great professor with a lot of charisma. He has hundreds of undergrad physics lectures on his youtube channel for anyone who his interested:  https://www.youtube.com/@AlexFlournoyTeacher/playlists 

I thought I'd highlight a few things he has said about his experiences teaching:

"You haven't really 100% learned something until you can completely and successfully explain it to someone else."
from:  https://www.youtube.com/watch?v=r27QB... 

"You should drop the habit of nodding in agreement, and the moment someone says something you don't understand... stop them, slow them down."
from:  https://www.youtube.com/watch?v=bl58i... 

"In almost everything that we do, there's more than one way to do it. And just because we have figured out a way to do it, that by no means means it is the only way to do it. And sometimes it's not the best way to do it."
from:  https://www.youtube.com/watch?v=1IsG_... 

Next video will be on Spin-1/2 representations of SU(2) and SL(2,C). Took a lot longer to get this one done than I wanted, but glad it's finished. 

Tomorrow morning I'll be posting my first video (of 5ish) covering Lie Algebras and Lie Groups.

Sorry for the long break since the last video. I was less familiar with this topic than I thought I was and needed extra time to get things right. 

A bit late posting this, but tomorrow is the last video in the Clifford Algebra part of my spinors series. I'll be talking about nilpotents and maximally isotropic subspaces.

This means I'm about 60% done the series! 

Tomorrow I'll be uploading a video explaining why spinors are members of "Left Minimal Ideals" in Clifford Algebras.

I'll also be explaining something called the "Pacwoman Property" while we're at it. 

I'm a little late posting this, but I crossed 100k subscribers a few weeks ago. Thanks so much to everyone for watching my stuff! I never thought monotone lectures about tensors and spinors would be this popular.

(I think at least 1/4 of this is due to the joke videos I've posted, but I'll accept the vanity plaque anyway.)
