In this thread we discuss the concept of extended real numbers and their properties
> topological compactification of R
>sup/inf always exist
> no need to carry around edge cases of convergence in definitions around, we can now converge to infinity
> limits of converging sequences just add together (unless one is infinity and the other negative infinity)
> "point/line at infinity"
> makes finitist seethe

are they based?

Scientifically speaking, how much longer until Florida, or at least a good 50-70% of it goes underwater?

Book

I have a problem /sci/

Every time I try to study programming I find myself picking at the bone and trying to understand it intuitively. \

By that I mean, I could easily become a developer or engineer but I find myself trying to understand how assembly language works or how the whole computing era started. Like all the way back to the abacus.

Pretty much, its like trying to be a biologist but I find myself trying to understand how subatomic particles work. It's not practical for life and having a job/degree. If I was an academic and had a money sure I would shut myself away and do some Newton eccentric thing, but I want to be productive.

I just need a book that LITERALLY goes from ground up.

Have any of you guys gone through this?

Instincts prove that we inherit memories or certain emotional associations through our genes. Will we ever be able to fully access the memories of our ancestors?

Motherfucking bullshit. Can you not raise complex numbers to a power?

Where can I find a software that does this?

Transhumanists evangelists and zealots are raiding /sci/ in an attempt to ruin the board because they're angry about the whole two genders thing.
Watch out for transhumanists spam and propaganda if you're going to brows this board, their garbage now constitutes a substantial fraction of the posts and threads on /sci/
