I ve read two links so far regarding to the kinetic theory

I googled exactly what u told me @FenderLesPaul

but I don't really see how this explains

0celo7

still no answer D:

privetDruzia

why you need these two conditions in order to

apply this law

They are just explaining that u can calculate

the force exerced by the particles due to their velocity (kinetic energy)

on the walls of the container

is there anything specific I should read about

FenderLesPaul

ok well that right there obviously relates to elastic collisions

now think about why you need negligible intermolecular forces

privetDruzia

21:07

and what id the collisions weren't elastic?

what would that change

0celo7

the force would depend on the intermolecular forces knocking the particles about

FenderLesPaul

you tell me

there's no point in me just telling you if you want to learn anything

privetDruzia

IDK, seems absurd:they d stop moving after a certain amount of collisions. No more movement means no gas=> liquid => gas. Omg...

*=>solid

this would seem incredible

that you could turn water vapor to ice by just "smashing" a brick against the gas!

FenderLesPaul

what

0celo7

...

privetDruzia

21:11

(some energy dissipates at each collision)

FenderLesPaul

so that affects the recoil velocity

which is a direct input into the derivation

privetDruzia

mhm

ok I ll try to reread the part with the derivations

FenderLesPaul

you're also ignoring internal degrees of freedom

yeah see where diluteness comes in

privetDruzia

FenderLesPaul

it's instructive to reproduce the derivation yourself using kinetic theory

since it mainly just uses Newtonian mechanics

if you're bored, also use kinetic theory to derive $PV^{\gamma} = \text{const.}$

which is somewhat more involved

privetDruzia

21:15

i m not bored

FenderLesPaul

well it's a fun derivation either way

0celo7

it's not fun

FenderLesPaul

it's a lot like the famous ball bouncing between moving walls problem in Kleppner

privetDruzia

what s the funniest thing you ve done so far

in physics?

FenderLesPaul

funniest?

privetDruzia

21:18

the thing where you had the most fun I mean

FenderLesPaul

I pissed on Weinberg's GR book that's pretty funny I guess

privetDruzia

hahahaha

FenderLesPaul

well that was fun too

0celo7

@FenderLesPaul the fuck

privetDruzia

no but regarding to what you learned/worked on

cause u r saying that doing derivatives is fun

FenderLesPaul

21:19

@privetDruzia I had a lot of fun learning GR

more so than any other physics subject

and I think my current GR research project is the most fun thing I've done so far, as far as physics goes

privetDruzia

what does GR stanbd for?

FenderLesPaul

@0celo7 I'm pretty metal

GR = General Relativity

0celo7

Great Rowdiness

privetDruzia

that s really very broad I think

I do have a lot of respect for people who study/studied physics

I am studying engineering

FenderLesPaul

ohh

privetDruzia

21:21

and truely believe that physics is much harder than engineering

FenderLesPaul

well then my idea of fun and your idea of fun is definitely going to be different haha

privetDruzia

what do u mean?

we r indeed both active in different domains

FenderLesPaul

I don't know about all engineers but the ones I know don't really do physics problems for fun

privetDruzia

mhm

there s one thing I d like to dive into

it s astrophysics

is this a difficult branch of phyics?

0celo7

@FenderLesPaul what am I

@privetDruzia I'm not sure you can rank stuff like that

FenderLesPaul

21:23

@0celo7 my trophy husband

@privetDruzia you should ask @ChrisWhite he's an astrophysics PhD

0celo7

Only if you're down for polygamy

privetDruzia

@0celo7, in engineering for instance I think you can. there are some things that are easier to calculate or conceive

FenderLesPaul

@0celo7 fuck that I need an exclusive emotional connection

0celo7

@privetDruzia yeah, I'm sure nuclear fusion (what I want to do) is "harder" than building a microwave

privetDruzia

hahahah true

0celo7

21:26

but I was talking about theoretical stuff

privetDruzia

no lie

FenderLesPaul

sophus lie

0celo7

@FenderLesPaul get a dog then

FenderLesPaul

I did get a dog

0celo7

you're not as good as @ACuriousMind and I have to make a choice

FenderLesPaul

21:28

it left me for another owner

sobs

0celo7

sucks to suck

privetDruzia

@ChrisWhite, hello @FenderLesPaul adviced me to ask my question to you. If everything goes well I should graduate pretty soon and I ll be an industrial engineer. I am really interested in aerospace engineering. Especially attitude determination and control systems for satellites. My dream would be to pursue a PhD in that area. So I was wondering whether diving into astrophysics as a preparation for my eventual PhD could be a good idea. Also what could be an interesting domain about astrophysics to learn about in order to be well prepared?

0celo7

still no answer from Lee RIP

privetDruzia

oh yhea I am extremely motivated, I am ready to do anything in order to be accepted and succeed

0celo7

He is researching black hole accretion disks

privetDruzia

21:32

sounds crazy

FenderLesPaul

@0celo7 I completely changed my hairstyle

0celo7

Uh, ok?

FenderLesPaul

thought you'd like to know

0celo7

Do you still look homeless?

FenderLesPaul

possibly

privetDruzia

21:34

do u know each other in real life?

FenderLesPaul

yes

0celo7

FenderLesPaul

but yes

0celo7

nope

privetDruzia

but yepe?

FenderLesPaul

21:36

pepe yepe

0celo7

you're a bad meme

FenderLesPaul

bo diddly

would you guys ever consider working with a professor who is 66?

Mike Miller

Yes.

0celo7

Why not?

FenderLesPaul

idk there are certain advantages to working with an older professor and certain advantages to working with a younger one

just wanted to know your thoughts

0celo7

21:47

If he goes senile you can take over Mrs. Reagan style

FenderLesPaul

they could die at any moment

0celo7

you could die at any moment

FenderLesPaul

from old age

0celo7

I know where you live

FenderLesPaul

0celo7

21:57

@FenderLesPaul be very afraid...

FenderLesPaul

nah

only one more week

and I won't be the only undergrad on campus anymore

2 hours later…

Bernard Meurer

23:42

This chat is awfully quiet

what gives?

0celo7

reading

ffs Dr. Analysis prof why are you making me do absolute value proofs :(

@yuggib However, my Japanese analysis prof defines the natural numbers without zero...that might make things awk if I mix the two up.
