Probably not, but that's why GR is elegant right, it takes some simple physical intuitions and then can generate very complex results.

iono :P

Semiclassical

QFT is weird because it feels like there ought to be some more unifying approach to it

enumaris

I have never seen one that has been satisfying

over all the textbooks I've looked at for QFT, the rules always feel somewhat arbitrary to me

Semiclassical

and yet, it works :/

enumaris

and yet it works...indeed...

=/

it does have a good number of unexplained parameters tho, like all of the masses of the fundamental particles, and all of the coupling constants

I wonder if it has more of those than most other theories...or if it's on average the same as other theories when you somehow account for the number of phenomena that it describes...hmmm

meta

Now I'm wondering if there's some way to classify theories based on some measure of (number of input parameters) vs (number of physical phenomena that it makes predictions on)

some sort of "generated-information density" function or something...

@enumaris let's go hard core on QM at 1:30pm pacific time. I will be in the math stack exchange chat for this. Come prepared to think fast and hard on the fly :P

enumaris

o.o

why would you do it in the math chat?

It's better to learn physics form physicists

Phase

Just make your own Chat

And invite people

enumaris

otherwise you'll just spend all your time making things rigorous

Phase

don't take over a whole room

that's already there

enumaris

(subtle jab at the mathematicians)

Phase

19:24

Don't punch a mathematician

They'll Morph into some topological equivalent

and start crying

enumaris

maybe

Q: How do I clear my concepts in physics?

I just wanted to know how do I know every question that is within the theory that I read and develop an approach to solving questions. Thanks, anything helps.

Did you hear about that farmer who got awarded the Nobel prize?

Indeed, I think being a good physicist might actually hinder being a good mathematician, and vice versa

Phase

He was OutStanding in his Field.

19:34

@Phase Don't you mean the Fields medal? ;)

Phase

nop but that also works : P

Im repeating the joke as it told to me from one Automated Dominos Delivery update thing

enumaris

hey

I'm a good mathematician

and a good physicist

Phase

I'm a terrible mathematician but on the other hand

I'm also a terrible physicist

enumaris

so we got all the cases covered

Phase

if we Fuse

we'll make a thoroughly average human being

enumaris

19:36

sounds good XD

Phase

Are you a happy or sad person

on average

enumaris

happy

Balarka Sen

im a sadboi

i should start doing some math

some 'o them good meth

enumaris

math is kinda like meth

not even once

Phase

@BalarkaSen you share a lot of my music taste but

im willing to bet you hate my pizza taste

anchovies, mushrooms, peppers, chicken, pineapple, chorizo

enumaris

19:49

ew

Phase

its tasty

Other than pineapple all look fine

I don't like sweet toppings

special meme fresh is a good aesthetic

enumaris

19:57

I don't like anchovies or chicken or pinapple or chorizo on my pizza

I like pepperoni pizza

Balarka Sen

r/surrealmemes is a heaven dave

Phase

pineapple and anchovies belong on pizza

enumaris

no

Phase

i will cash in my loyalty card with ACM and have you banned sir

how dare you disagree with me on pineapple aesthetics

pineapple looks good

and

it tastes good

on pizza

Anonymous

You probably ~~use~~ eat genetically modified pineapples then :P

Phase

20:05

m8 all pineapples are genetically modified, how else could they be so great on Pizza

its unnatural

pepperoni pizza ftw

Phase

I would say that pepperoni pizza is isomorphic to trash but it's honestly just identical to it

enumaris

no

Q: "The Schwarzschild Proton" paper - Is the science valid?

I'm a layman without a university background in physics / math. Since I don't have a background, reading a paper is more of an effort. Consequently, when I come across an interesting paper, I can't really just give it a glance, and see if it is science, or psuedoscience. This question is about ...

particle-physics

I started reading a paper with that title once ...

CooperCape

I just had a dream about diagonalising matrices smh

Mithrandir24601

@CooperCape I wish someone would come along and diagonalise my matrix :/

dmckee

@CooperCape Everyone I've ever asked who did grad school in physics dreamed math at some point during their studies.

CooperCape

@Mithrandir24601 Sounds... fun. ;)

@dmckee Not even started my studies... where does this path lead.

Mithrandir24601

@dmckee Sounds 'bout right

dmckee

20:47

@CooperCape There doesn't seem to be any lasting harm. But it left me very puzzled when I woke.

enumaris

I never dreamed about math

only physics

dmckee

For me it was spherical harmonics, their orthoganlity and recursion relations. Yikes.

enumaris

cus I'm a true physicist, ain't no maths here

CooperCape

@dmckee Don't know what that is... sounds... uhhh. Quadratic equations anyone? ;p

dmckee

Wikipedia has an article if you are curious: en.wikipedia.org/wiki/Spherical_harmonics

CooperCape

20:54

Way beyond me... Looks orbital shells tho

enumaris

it's basically those orbital thingies you see from chem

CooperCape

wild

enumaris

it's the mathematical representation of them

CooperCape

pretty neat

enumaris

Or I should say

Cows

21:01

ok I just ate

yeahh h

enumaris

Oribitals are represented mathematically by the spherical harmonics

you use spherical harmonics to do much more than model orbitals

Cows

had to cook . Made purple cabbage, rice and salmon

CooperCape

I can imagine...

Cows

and just took my vitamins and a cup of probiotic yogurt.

I'm living the life folks

:D

wooohooo

enumaris

yuck

Cows

21:04

It's almost 1:30

hmm I can't seem to relocate the room i was exploring qm in yesterday. can we create a room to explore qm?

here

@enumaris can you help me create a room so we could discuss qm?

enumaris

I dunno how to create a room

I mentioned entanglement in my room and everyone left

0celo7

No

Cows

wow lol

why not

lol

Bernardo Meurer

@Cows He thinks entanglement is immoral

He only believes in entanglement after marriage

The fact that emojis are part of Unicode haunts me every day

Transport and Map Symbols

Transport and Map Symbols is a Unicode block containing transportation and map icons, largely for compatibility with Japanese Telephone carriers' emoji implementations of Shift JIS and to encode characters in the Wingdings and Wingdings 2 character sets. == Block == == Emoji == The Transport and Map Symbols block contains 94 emoji: U+1F680–U+1F6C5, U+1F6CB–U+1F6D2, U+1F6E0–U+1F6E5, U+1F6E9, U+1F6EB–U+1F6EC, U+1F6F0 and U+1F6F3–U+1F6F8. The block has 46 standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the following 23 base characte...

good night

@BalarkaSen yes

the name's dude

@Cows are you still available???

good night

@BernardoMeurer ill livestream it

Balarka Sen

what is dude blackmailing you for

good night

lmao

his fear of people running in the cold

i'm gonna expose him

Bernardo Meurer

What

good night

22:45

do i know you?

Bernardo Meurer

Yes

Balarka Sen

confused

good night

@BalarkaSen don't worry

it shows character

lack of conversational awareness shows that you have better priorities in life

Balarka Sen

I will never know if that is meant as an insult or a compliment. I'll take that as a meme.

good night

exchuse ME
