Not sure where the right place would be to put this, but I just noticed that Borcherds has videos of lectures he has given. I had seen the ones on schemes, but he has now a good selection of topics. They are not only algebraic, so may be the general forum would have been better, but anyway here it is.

I found his biography on Wikipedia:

Richard Ewen Borcherds (/ˈbɔːrtʃərdz/; born 29 November 1959)[2] is a British[4] mathematician currently working in quantum field theory. He is known for his work in lattices, group theory, and infinite-dimensional algebras,[5][6] for which he was awarded the Fields Medal in 1998. He is well known for his proof of monstrous moonshine using ideas from string theory.

It's pretty interesting that he proved the Monstrous Moonshine theorem using string theory.

The relationship between the montrous moonshine group and modular forms.



The other interesting thing he was a doctoral student of John Horton Conway.

Damn that's amazing. I had no idea.

He says that everyone hates statistics so they change the name to things like "data science."

Sometimes in order to find a job you have to "bite the bullet" so to say... :oldmad:
 
Yep thats wuite popular in comp sci business products.

Years ago IBM had a database product called ISAM vs GE’s ISP. ISAM was indexed sequential access method vs indexed sequential processing.
 
Thread 'Determine whether ##125## is a unit in ##\mathbb{Z_471}##'
This is the question, I understand the concept, in ##\mathbb{Z_n}## an element is a is a unit if and only if gcd( a,n) =1. My understanding of backwards substitution, ... i have using Euclidean algorithm, ##471 = 3⋅121 + 108## ##121 = 1⋅108 + 13## ##108 =8⋅13+4## ##13=3⋅4+1## ##4=4⋅1+0## using back-substitution, ##1=13-3⋅4## ##=(121-1⋅108)-3(108-8⋅13)## ... ##= 121-(471-3⋅121)-3⋅471+9⋅121+24⋅121-24(471-3⋅121## ##=121-471+3⋅121-3⋅471+9⋅121+24⋅121-24⋅471+72⋅121##...
