Books, even the " beginners' " ones, are by their very nature much more concise, which is what makes them hard to read for the novices they are intended for (the irony!). My suggestion is to make the most out of these lectures and use the acquired knowledge to read a college level book (the Artin seems to be regarded as one of the classics). Good luck with your journey!
I had the same question: comes down to the fact that the group represents all the rearrangements of its objects while preserving the structure (not introducing any new objects). That's what a symmetrical transformation is, you change things around but keep the original structure.
These videos are repetitious to the point of being unwatchable. I once heard a good teacher say “tell them what your going to tell them, tell them, then tell them what you’ve told them” but this is ridiculous. It’s like watching an episode of Romper Room where Miss Barbara says “Don’t forget children: 1+1=2” every thirty seconds.
Thank you! You are a gift from God. You explained it so well. Every one of your videos I get an aha moment.
Thank you for your hard work
Thank you :)
nice and perfect. now i understand why group theory is important at chemistry
Group theory is almost everywhere, once you learn it you can see how it’s used in chemistry, cryptography, physics, algebra and many other topics!
Perfect! thx for the videos. I have a question though, which text-book is closer to your way of teaching in group theory?

In part 1 you used sigma now you're using tau. Any particular reason?
I should have said for C2.
Symbol tau is used for transposition, which is the same as rotation when you have only 2 -element set, {1, 2}.
Hi! Can you please explain how the symmetric group is symmetric?

i hope he doesnt do this to his patients when setting a diagnosis or explaining a medical test
