Now I want a book of this, but with all of quantum mechanics

And God said, "Behold! I have created the fourth primordial force: the weak interaction!"

And the angels all clapped and nodded politely, and there was a long silence; and finally Verchiel, the Angel of Grace, spoke up and asked, "Er, what exactly does it do, O Fashioner?"

And God said, "What do you mean, 'what does it do?' It's the fourth fundamental force of the universe."

And Verchiel said, "You mentioned that. Um. But it's just that the other three sort of have a brand, you know? Gravity helps build large-scale structures, acts over vast cosmic distances, shapes time and space. The strong force is secret, hidden, binding together quarks and all that. Electromagnetism, very cool stuff, somewhere in between. We're all big fans of the whole magnetic monopole double bluff, very clever. But, er. What does this 'weak interaction' do?"

And God said, "It mediates radioactive decay. Sort of."

And Verchiel said, "Radioactive decay? All radioactive decay?"

And God said, "No. Just some kinds."

And Zephaniel, the Chief of the Ishim spoke, and he said, "A whole independent force just to mediate some kinds of radioactive decay?"

And God said, "Well. Not totally independent. Technically it's related to electromagnetism."

And Zephaniel said, "Wait, it's not even a real force?"

And God said, "It's totally a real force. It's just that it's one aspect of a combined electromagnetic and weak force. An electro-weak force, if you will."

And Metatron, the Celestial Scribe, scratched his head at this, but said nothing.

And Cambiel, the Angel of Transformation, said, "Maybe you can walk us through it from the top."

And God Sighed an immense Sigh, and said, "All right, fine.

"So the way it works is that all of space and time is permeated by a field that has imaginary mass."

And Cambiel said, "Imaginary mass, O Generous Provider?"

And God said, "Yes, imaginary mass. It's tachyonic, d'you see?"

And Sarathiel, the Angel of Discipline, said, "Wait a minute, I thought we agreed nothing was going to travel faster than light? All that 'c' business and the whole Lorentz transformation thing. What's happening with that?"

And God said, "Let me finish. The field is tachyonic. The particles in the field all move slower than light."

And Sarathiel had to think about this for a second.

And God said, "The point is, a field with imaginary mass has a non-zero vacuum expectation value."

And this really gave Sarathiel trouble, since he had never been very good at math.

And God, seeing this, went back to explain. "Most fields, like the electromagnetic field, have no effect when they are at their lowest energy state. It's like they're not there at all. If you give a field imaginary mass, then it vanishes only when it's at a very high energy state, and at a low energy state, it has a nonzero value everywhere."

And Sarathiel nodded, but he was confused, because he didn't understand why God would create such a thing.

But Verchiel thought he saw where God was going with this, and he was amazed.

"Truly, you are cunning beyond measure, O Only One Certainly Sound and Genuine in Truth! Only now do I understand your design! For in order to make the universe homogenous and isotropic, it is necessary that all large-scale fluctuations in temperature and mass must be evened out early in the history of the cosmos; and therefore, you have designed a field which will rapidly expand space after the Big Bang, many orders of magnitude in brief moments, and then swiftly and spontaneously decay as it gives up the energy it began with, giving rise to radiation and particles of all kinds as it does, which will condense into the material universe! It is a wonder to behold."

And God said, "What? No. I mean I did, but this isn't the inflaton field I'm talking about. This is something else."

And Verchiel said, "Wait, it's not?"

And God said, "No, I'm going to use a different field to drive cosmic inflation. The properties of this field are totally different."

And now Verchiel was also confused, and lapsed into silence.

And God said, "Like I was saying, this field is a scalar field with imaginary mass, and it does spontaneously decay to a ground state with a non-zero value. But it's not the inflaton field. Instead it combines with the W1, W2, W3, and B bosons."

And Metatron began to flip back through the pages of the Heavenly Record trying to figure out where he'd lost the thread.

And Zephaniel said, "The what bosons?"

And God said, "The W1, W2, W3, and B bosons. I'm sure I mentioned them. You know, the massless bosons?"

And Zephaniel said, "I'm pretty sure we only talked about the W+, W-, and Z0 bosons. All of which you said were going to have mass, O Owner of All Sovereignty."

And God said, "Yes, but this is how they get them, you see. Once this field acquires a nonzero value everywhere, the massless bosons interact with it and get mass. Well, some of them do. They turn into the W+, W-, and Z0 boson. And the photon."

And Zephaniel said, "…and the photon, O Accepter of Invocation?"

And God said, "Well, I did say I was going to unify the electromagnetic force and the weak interaction, didn't I? This is how. Above the critical temperature--right now I'm thinking 10^15 K, but I'm open to feedback on that one--electromagnetism and the weak force act as a single unifying force. Below that temperature, the field gets a nonzero value, you get three massive bosons to mediate the weak interaction, and the photon pops out seperately."

And Zephaniel said, "That seems… a bit overly complicated, doesn't it, O Reinstater Who Brings Back All?"

And God said, "No, it's exactly what we need. Look, that way the W and Z bosons have something to do, but the weak interaction still only travels short distances. Gravity is still the star of the show on cosmic scales, as it were. But now quarks and leptons can swap their flavor!"

And Zephaniel said, rather weakly, "Their… flavor, O Source of Good?"

And God said, "It's this new quantum number I'm trying out, to give the three generations of matter more unique identities."

And Cambiel said, "Three generations of matter? Now I'm really confused."

And God said, "I'm sure I mentioned this. You've got the lightest quarks and leptons, and then two heavier versions of each that can decay into the lighter versions."

And Cambiel said, "What do they do? New kinds of chemistry, is it?"

And God said, "Well, no. Mostly they just decay in a couple microseconds. Or even faster."

And Zephaniel began to rub his temples, and Cambiel sniffed.

And Cambiel said, "This all seems a bit ad hoc to me. Not really the stuff of an elegant and obviously ordered Creation. Why not have four generations of matter? Why not a trillion?"

And God began to grow irritable, and said, "Well, that's not really up to you, now is it? We're going to have three generations of matter, and the electroweak force, and that's that!"

And Zephaniel said, "As long as we are unifying fundamental forces, perhaps we could somehow also unify the electroweak interaction with the strong interaction, or even gravity."

And God hesitated saying, "Well, I haven't decided about that yet. I'm not sure I want gravity to be quantized, you know? Seems to take some of the geometric elegance out of general relativity."

And now it was Zephaniel's turn to sigh, and he bowed his head. "As you wish, O Possessor of Authority of Decisions and Judgement."

my psych book:

Thinking about their parallels. I am NOT okay.

i dont think i’ll ever get over how at peace kunikida looks here. i don’t really know how to phrase if but it’s something about how kunikida has always been ready to sacrifice himself, how he has never shied away from death’s door, as if that is the only way he can truly fulfill his ideals

what will kunikida do when he finally achieves it all? i believe he sets this perfect, ridiculously high standard for himself for a sense of purpose, or rather a reason to live. will he still choose to live without it?

there’s something symbolic about how kunikida separates from his notebook when he sacrifices himself. it’s as if he is tethered to living because of his ideals, and when he goes, he leaves behind his notebook, releasing himself at last

jouno once asked if he was relieved to be freed from his self-inflicted burden. at that time, i believe the answer was still ‘no’, for it wasn’t fully his choice. he still had much to do, the agency was messy and running, he couldn’t truly die in peace

this time, even though i don’t believe he’s fully dead, i think kunikida is okay with dying here. because atsushi just saved junichirou! he chose to fight for what’s left instead of ceaselessly grappling for something already fading. it’s something that kunikida has taught him since the very first day—think about what you can do. kunikida himself wasn’t able to save them, but atsushi did, and in him, his ideals will continue to live. atsushi’s actions showed him that even if he dies, they’ll be okay. they’ll be okay without him

i think that’s why this is the most at peace we’ve ever seen kunikida. to know that his teachings have impacted someone and that it wasn’t all for naught. this is relief

Wow now that I think about it it's incredibly dumb

its been p common knowledge for decades that light pollution can be massively reduced by just putting shades on streetlamps, and that doing that would save energy, help wildlife, and let us see the stars better, but are society says if u wanna change any minor little tiny thing u gotta dedicate ur whole life to campaigning for it and this is a good ways down the list of priorities for most ppl, so instead i gotta walk past newly-installed streetlamps that are just dumb glass globes that use half their electricity to blast half their light directly into the sky where it does only bad things for no reason and think "we should overthrow the government"

We have lived long enough to become the villains and I'm NOT here for it

watching gen z and millennials make fun of gen alpha has been torturous. "But they're actually stupid" 1. theyre middle schoolers 2. isn't that what older gens said about us? don't you remember being 11?

it truly is just "impulse reaction to cringe <- has not yet unlearned shame"

the cycle continues let me out of here

guys. guys I think we should kill cringe culture

Hey guys I think it's enough with the new inventions thanks

i don’t like how endings in real life come on so suddenly without making sense, without much warning. one minute you’re in the middle of something and the next it’s all a very long time ago and you’re a different person and none of it is ever coming back

"Be not defeated by the rain"

Be not defeated by the rain, Nor let the wind prove your better.

Succumb not to the snows of winter. Nor be bested by the heat of summer.

Be strong in body. Unfettered by desire. Not enticed to anger. Cultivate a quiet joy.

Count yourself last in everything. Put others before you.

Watch well and listen closely. Hold the learned lessons dear.

A thatch-roof house, in a meadow, nestled in a pine grove's shade.

A handful of rice, some miso, and a few vegetables to suffice for the day.

If, to the East, a child lies sick: Go forth and nurse him to health.

If, to the West, an old lady stands exhausted: Go forth, and relieve her of burden.

If, to the South, a man lies dying: Go forth with words of courage to dispel his fear.

If, to the North, an argument or fight ensues:

Go forth and beg them stop such a waste of effort and of spirit.

In times of drought, shed tears of sympathy.

In summers cold, walk in concern and empathy.

Stand aloof of the unknowing masses:

Better dismissed as useless than flattered as a "Great Man".

This is my goal, the person I strive to become.

Proud library supremacist

You guys rlly don't realise how much knowledge is still not committed to the internet. I find books all the time with stuff that is impossible to find through a search engine- most people do not put their magnum opus research online for free and the more niche a skill is the less likely you are to have people who will leak those books online. (Nevermind all the books written prior to the internet that have knowledge that is not considered "relevant" enough to digitise).

Whenever people say that we r growing up with all the world's knowledge at our fingertips...it's not necessarily true. Is the amount of knowledge online potentially infinite? Yes. Is it all knowledge? No. You will be surprised at the niche things you can discover at a local archive or library.

jujutsu kaisen s2 // the song of achilles

collection of useful things tumblr has taught me:

even if you can't fall asleep, laying down with your eyes closed will still rest your body

you don't have to brush your teeth standing up

you don't have to do any chore standing up, from dishes to showering

you don't have to shower with the lights on

if you can't brush your teeth, flossing and a tongue scraper gets rid of plaque and bad breath

if you can't do that, mouthwash kills a lot of bacteria

eating "unhealthy" food is better than eating no food

you can make the same meal everyday for however long you still want it

some pills come in syrups or chewables if you can't swallow them

kids nutritional shakes can be a quick way to get fuel if you can't eat/don't have time

if walking hurts/exhausts you on a regular basis, canes and rollers are for you, no matter how young you are

we have free will—if doing something "out of the ordinary" makes life easier for you, do it
