Very nice and a good way to start 2021! Your lectures are not just interesting, they are also fun. Your love of mathematics is obvious and enhances your teaching.

Cries in doesn't understand group theory

[MichaelRothwell]

Thanks, so refreshing to see a bit of algebra to start the year in an upbeat way!

[julimate]

Very clear and fun to watch! Thank you and my algebra teacher for leading me to understand the importance of 2021

[Gerdybass]

Great video! And also the "probably by Cauchys theorem, idk" theorem appears, very powerful theorem :P, niice 9:40

Would love to see even more group theory on your channel! Really liked this video.

Wow! That's exactly what i'm studying! For the next exam of algebra me and my friends have studied the last decade lol. But unfortunatly, since the only 2021 order group is ciclic, it will probably not be in the exercices!

Until now I have understood everything shown by Dr. Peyan. Today he started with 2021=43*47 and then he stopped to speak English.

0:39 "there are many groups of order 6"

I don't think you can use the word "many" to mean the number "2"

Lol it took me a while to understand you're not talking about Ceelo green but a great boost of information

26:08 "...I hope that 2021 brings lots of happiness and algebra" :) "...even though they do commute" :(

Watching the video and good job on editing!!!

[PositronQ]

Yeah, yesterday I did something similar when I saw "adiós 2020"

[xioxy]

Just after finishing abstract algebra part 1 in college. I kind of understood it but I guess there is still some practice needed to understand it better 😅

[lorisdeplano]

Absolutely amazing video, I love group theory!

[saraukasik]

I find this video very cool! Thanks for making it. :D

This year is the 200th anniversary of Greece's revolution against the Ottomans🥳🥳🥳🥳

I don't know, I'm so used to the multiplication of sets being A×B={(x, y)/x is in A and y is in B}

What formulas did Terrence Tao invent??
