After a long absence, I think I might be able to release the Spinors for Beginners 21 video (95-minutes!) on the weekend.
Hopefully I don't find any major mistakes until then!

Hi all. I realize it's been a few months since I've uploaded. I haven't forgotten about my series on spinors. It's just that the next video (which is an intro to quantum fields) has become quite long--approximately 90 minutes. I'm working on finishing it up now. After it's complete I'll probably upload the whole thing as "Spinors video #21", and then chop it into pieces and upload it again as its own mini-series. I hope to have it done this month.

I'm hoping I'll be able to upload my next video on Sunday. It will be a deep dive on the properties of the Dirac Equation and Gamma Matrices.

Also, I've "skipped" a video yet again. Video 21 is going to be an introduction to QFT, but it's taking me longer to put all of that together. I'll get video 21 out later.

Spinors for Beginners 20 should be uploaded this weekend, probably Sunday.

Sorry for how long this one took. There's a *lot* of details in it, and it's currently sitting at 53min long. Representation theory has definitely been the most confusing part of this video series for me so far. I'm hoping this video will lay out the Lorentz group/algebra representations clearly.

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: news.snbc13.com/alex-flournoy-colorado-professor-dā€¦

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: 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.
