What's something that's notoriously hard to understand

>>7943992
What is the square root of negative four and can I divide it with a number closer to zero than itself and receive a dividend of positive four?

sqrt(-4) = 2i

okay

>can i divide it with a number closer to zero than itself and receive a dividend of positive four

...no...

the fact that the dividend be closer to zero than itself would not allow for the dividend to be four...

Tunnel field-effect transistors. One of those spooky esoteric black-magic things that work and have predictable properties but nobody I know actually ''''knows''''' why they work.

For some reason normies can't grasp pointers. I am not sure why.

why do people find them so difficult? it's literally in the name.

Negative numbers aren't real, its just a positive number in another direction, square roots of negative numbers are purposeless.

Just interviews a bunch of college students for internships at my company for software development.

Not many can wrap their heads around recursion.

Triple integrals, because that's the point where STE babbies divide from the M at my uni. Babby Proof technicuqes are also another candidate because that's where the CS babbies divide from the M.

>>7945885
I just proved that if n > 0 then n + 1 > 0 by recursion.

topkek I am a CS freshman and I'm already coming up with PhD math material?

Git fucking gud m8.

Personally it was the syntax. It's super simple stuff now that I've used C++ a bit but initially, reading code with * and & literally everywhere, took some time to get use to.

The concept of a pointer is pretty simple and straightforward.

>>7945990
I'm not a CS major, dick bag. Had to update software on our products because the original developers went under, so learned some basic C++.

I'm just saying, I can understand why it would be the first thing people would be confused by.

But please, continue riding your high horse into the sunset.

A postdoc in algebraic topology told me that Perelman's proof of the Poincaré conjecture is notoriously hard to understand.

In my field, in some sense the fundamental theorem of forcing qualifies. While forcing in practice is fairly easy given the fundamental theorem of forcing, holding the whole construction in one's mind at once is very difficult. I have heard grad students in set theory who have been utilizing forcing at the research level for years say they feel like they still don't truly understand forcing.

>>7945826
because its difficult to keep track of pointers when writing functions that manipulate them with recursion

>>7946292
>actually using recursion outside of an academic setting

>>7946275
Well this is a pleasant surprise: A person who understands forcing. And on /sci/ no less. What uni?

It's literally the best way to write code that's easily provably correct.

Lmao just fucking kill me

Did Venus once have plate tectonics before it transitioned to a solid lid tectonic system? What is Titan's disappearing island?

the fucking thought process of my fucking students

>>7945816
I don't understand the difficulties with it too. For me pointers are actually a far easier concept than getting used to every programming languages personal call by value//reference-scheme.

Why would someone do this?

I still can't understand how the fuck did they come up with all the hardware ideas. Like how the fuck do you do all this shit with just 0's and 1's. That's why I love the degree tho.
