#pauli’s exclusion principle

[alvinmichaelmurphyseville]

“Got sent to the principal’s office today for reading in class. Granted, what I was reading wasn’t exactly related to the classwork.”

“But, hey, you know, can I help it if the Pauli Exclusion Principle is more riveting than Catcher In The Rye or whatever it’s called? Now, I’m hungry for pastrami on rye bread.”

“But anyway, I was inactive for a bit because Dave made us all take a Tumblr detox week. We’re allowed to post again now.”

“Are there any topics in particular you’d like me to talk about?”

I identify as a degenerate orbital

[whats-in-a-sentence]

An electron, for instance, can be thought of as a particle – one that can leave a dot on a phosphor screen, as in Figure 4.4 – but can (and must) also be thought of in terms of a waving field, one that can contribute to an interference pattern on a phosphor screen as in Future 4.3b.³

3. One difference between force and matter fields is expressed by Wolfgang Pauli's exclusion principle. This principle shows that whereas a huge number of force particles (like photons) can combine to produce fields accessible to a prequantum physicist such as Maxwell, fields that you see every time you enter a dark room and turn on a light, matter particles are generally excluded by the laws of quantum physics from cooperating in such a coherent, organized manner. (More precisely, two particles of the same species, such as two electrons, are excluded from occupying the same state, whereas there is no such restriction for photons. Thus, matter fields do not generally have a macroscopic, classical-like manifestation.)

Happy deathday to Wolfgang Pauli, whose exclusion principle doesn't apply to bosons, and I think that's exclusionary in and of itself

[son-of-dracula-flow]

Pauli Exclusion Principle? Pauli felt excluded when I fucked his wife. Now I can walk through walls.

I just love it when video games let you do really stupid shit that kills you immediately. I love being like "oh this is a terrible idea" and being able to do it and then die. It's good game design.

theorising : us in parallel worlds

୨୧ ; you and jake sim are in completely different orbits! how did you defy the laws of physics and end up with him?

pairing! physicalsciencesmajor!jake x historymajor!reader | wc. 0.8k | warnings: possibly incorrect science and uni terms, attempted humour, probably cringe EN-

🖇️ : jake version is out now!! this was so cute to write and the reader is so me i can’t do maths and physics either ㅠㅠ need jake to tutor me frfr

so you see

you’ve never been maths and science smart

you’ve always been better at the humanities subjects and the languages, even from middle school

you are the history, geography and literature ACE.

well, jake’s the opposite

he devours maths equations and quantum physics papers for breakfast and proceeds to choke over basic history — more under cut!!

“when did the first world war end?”

“uh, i dunno. BUT did you know something can be a wave and a particle at once?”

jake was the kid that memorised the digits of pi FOR FUN.

he’s the guy who understood organic chemistry and quantum physics when he was nine

like you didn’t even have a consciousness when you were nine how tf was jake understanding quantum physics

of course jake’s a physical science and engineering major

you meet him at uni in your history department because he was waiting for his friend to come out of lecture

and DAMN he’s a lil cutie

you just watched him leaning on the hallway wall whilst you were sitting on that one random really comfortable sofa in the corner

you were NOT expecting him to suddenly stroll over to you

like why is that guy walking over to the sofa WHY IS HE LOOKING AT YOU

he's just here to ask you where the hell the lecture hall for the class that teaches history about people who died a lightyear before is

and you’re just like “oh, you mean ancient history? it’s right over there, room 204.”

he shoots you the most beautiful smile you've ever seen and says "thanks" before leaving

you're just kind of sitting there staring at his retreating figure

WHY IS HE SO SO CUTE????

it might not show but jake's also silently thinking about that

how did he not notice someone like you sooner?

like you're perfect it doesn't matter that the campus is huge and you two are different majors HOW HAS HE NEVER NOTICED YOU

you never even got to know that guy's name and you're scared that you won't ever see him again

you're just mentally kicking yourself for not asking for his name (and number)

you only manage to find him through intensive, if not obsessive internet research with your best friend

you learn that this cute guy's name is jake sim and that he's double majoring in physical sciences and engineering bc he's a lil crazy

how is his skin glowing with that kind of schedule

you always look for him in the university hallways YOU EVEN GO TO THE SCIENCES DEPARTMENT

but you never find him (it's because jake's poking his nose into every history lecture hall instead of being in his department trying to get a glimpse of you)

like he even goes to the philosophy lecture halls bc you sometimes go to them for fun

it’s giving zeno’s paradox omfg ITS GIVING PAULI EXCLUSION PRINCIPLE (except yall aren’t an electron)

but in one of your university's annual festivals you get to see him again!!

you were just in line to buy some lemonade with your friend when he lines up behind you

he recognises you straight away and gives you that smile that's been embedded in your memory for the past month and says a little hello

your friend just leaves because she's been getting daily updates about this guy named jake sim with pictures included

you're just left alone with him and you're so busy staring at him that you don't hear the lemonade stand cashier ask what you want to order

jake buys you a cup of lemonade SUCH A GENTLEMAN

you two have so much fun together at the festival

jake evens wins you a plushie with the darts at one of the stalls

"how're you so good at that? those games are designed to make you lose."

"you just need to understand the science behind it."

turns out jake is really easygoing which you didn't think was possible from an engineering major

you two make plans to meet up together and study at the science department library

tell me why the science library is so much better than the one you go to.

the sofas are so much more nap friendly and it just looks prettier yk

jake helps you with your maths and science studies

you thought you would be free of maths and science once you graduate from high school but turns out basic classes are in the core curriculum

it was a very big disappointment when you found out WDYM YOU STILL HAVE TO DO CALCULUS

you barely managed to do long divisions in primary, you can't do this shit anymore

it's okay, not only is jake really really smart, he's also really really patient

in return, you help jake boost his shitty core humanities grade

he's been barely scraping by

"y/n, i swear, i can memorise dates and all that stuff but i can't with the essays."

jake confesses to you during one of your little study sessions

he sends you a cute heart on the desmos graphing calculator (such a nerd omg)

you two are THE power couple

you get As in your maths and science now and the professor doesn't give you dirty looks anymore

jake managed to boost his grade as well DREAM COUPLE FRFR

Quite the rabbit hole Ethan has given us. Dive right in!

Why don't neutrons bind together?

#AskEthan

Protons and neutrons bind together to make nuclei.

But neutrons and other neutrons could theoretically bind together to make their own "neutronium" nuclei.

Here's why they don't.

[whore-ratio]

other girls say "I wanna be inside you" and they just wanna like fuck you or something. listen. I want to be INSIDE you. I want to violate the pauli exclusion principle. I want to fuse nuclei, okay? I want to eradicate everything in a ten mile radius with the strength of my attraction for you. I want our cuddles to have a body count they'll build memorials about

[elementcattos]

the pauli exclusion principle is that subatomic particles can't get closer than a certain distance from each other because they are in fact tiny billiard balls

[whats-in-a-sentence]

Octahedral complexes of Zn(II) and high-spin Mn(II) are also often colourless, or nearly so, but for a very different reason; Zn(II) is a d¹⁰ metal ion, meaning that the t2g and eg sets of orbitals are full (figure 13.40). (...) High-spin Mn(II) has a d⁵ electron configuration as shown in figure 13.40; to promote an electron from a t2g orbital to an eg orbital, we would require the electron involved to change its spin during the transition, otherwise a situation would result in which two electrons with the same spin occupy a single orbital, in violation of the Pauli exclusion principle.

Note: some of these are "pure" chemistry, some may be strongly related to other fields. As promised, I make fairly liberal choices on the intersection of sciences and they aren't always objective, but the videos are always chemistry-related. Enjoy!

“You’ve never touched anyone.

Not once in your life.

Every hug, kiss, or handhold is an illusion.

Zoom into matter—atoms don’t touch. Electrons repel each other.

What you felt wasn’t them-it’s a construct of your brain.

Energetic fields resisting each other.

(The Pauli Exclusion Principle.)*

And yet—it’s the most powerful force you’ll ever know.

Because connection isn’t physical—

it’s something much deeper.”

*Pauli's Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. In other words, no more than two electrons can occupy the same orbital and two electrons in the same orbital must have opposite spins. Image: edit: Mahaboka

[deadscientistssociety]

Hiiiii

Today I worked on quantum numbers and that was an amazing!🤩

Basically they are useful cause they help with getting an idea of the presence probability of en electron in an area!!! There are four quantum numbers n; l; m; s

Those four numbers describe a zone where an electron may be in an exact moment. 🤓

As an exemple: if you wanna send a letter you’ll put the location getting more precise little by little, Name the country, the city, the street, and finally the number.

It’s the same!!! n means the country (in that case the layer), L means the city ( in that case the underlayer), m means the street (in that case he’s called the magnetic number) and s means the number (in that case the spin)

⚠️Things to know : two electrons can not have the exact same address, that’s the Pauli exclusion principle⚠️

For exemple: for the oxygen which atomic number is 8 we’ve got that electronic location: 1s2, 2s2, 2p4.

Don’t forget it’s all about probability, those numbers describe a zone where the electron may be. That was really short and brief so if you like this topic you should explore this subject with more details!

Don’t forget I’m just a nerd student in first year of chemistry studies, not a teacher nor a professional, I just wanna show my passion and find out other science lovers!

If you have anything to add or if I did any error about chemistry or English feel free to tell it comments I’d love to read that!
