Also mathematicians: here’s this cool new thing, I called it “infinitesimal”
near zero

In computer engineering we have positive and negative zero.
Gladaed@feddit.de 2 years ago
Also in Math.

Unknowingly from the GP, that’s where CE got it from.

What algebra uses negative 0?
PlexSheep@infosec.pub 2 years ago
What do you mean? In two’s complement, there is only one zero.
yetAnotherUser@feddit.de 2 years ago
IEEE 754 floating point numbers have a signed bit at the front, causing +0 and -0 to exist.
henfredemars@infosec.pub 2 years ago
Specifically I was referring to standard float representation which permits signed zeros. However, other comments provide some interesting examples also.

HexesofVexes@lemmy.world 2 years ago
And, as a mathematician who has been coding a library to create scaled geometric graphics for his paper, I hate -0.0.
Seriously, I run every number where sign determines action through a function I call “fix_zero” just because tiny tiny rounding errors pile up in floats, even is numpy.

Limit x->0 { x } = 0 ? Noway
pumpkinseedoil@sh.itjust.works 2 years ago
Wait do you actually say “limit” instead of “limes” in English?
something_random_tho@lemmy.world 2 years ago
Yes, as in “Why can’t I hold all these limits?”
mexicancartel@lemmy.dbzer0.com 2 years ago
I usually uses lim
PM_ME_VINTAGE_30S@lemmy.sdf.org 2 years ago
Yes.
ShaunaTheDead@kbin.social 2 years ago
Yeah, I was gonna say... Calculus is all about saying it's infinitely approaching zero so let's assume it is zero.
KillingTimeItself@lemmy.dbzer0.com 2 years ago
i mean, mathematically speaking, every number that isn’t zero, is further away from zero, than the number before it.
So there is a point to the statement of “approaching zero” as well “near zero” and “about zero” since 100 probably isn’t about zero.
Also CS nerds would like to fight you about floating point values.
cucumber_sandwich@lemmy.world 2 years ago
Whoa slow down there buddy. Proposing numbers before numbers like they are a given.
KillingTimeItself@lemmy.dbzer0.com 2 years ago
as far as we can tell, mathematically, they are a given, and they never stop.
I’ll wait for you to find the end of pi.

“small but non-zero” is one of my favorite phrases 😅

cosmologists: sin(x) ~= 10

lets ignore the higher order terms for now. five lines below look at this beautiful exact equality that we got

What about large values of zero?

A mathematician, a physicist and an engineer are led into a long room. At the other end stands a beautiful naked woman. “When I ring this bell,” she says" you may cross half the space between us. When I ring the bell again, you may again cross half the space between us." Both the mathematician and physicist groan and wander off. “Ah, it’s Zeno’s paradox, we can never actually reach her.” The engineer, waiting for the bell, says “I think I can get close enough.”
KillingTimeItself@lemmy.dbzer0.com 2 years ago
why is there a naked woman?
captain_aggravated@sh.itjust.works 2 years ago
For the joke to work.
NegativeInf@lemmy.world 2 years ago
Because humanity has no other desires between math and tits apparently.
echolalia@lemmy.ml 2 years ago
Only straight men are mathematicians, physicists and engineers. This is why the joke is framed this way.
See: responses from OP, valiantly defending his choice to “piss people off”, instead of noticing the joke is just yet another reminder that men are default.
After all, sexism is over, and STEM isn’t hostile to women/non-heteronormative people. It’s all in our head.

Sexism, obvs
