My third year thermodynamics course opened with a similar quip by the lecturer. Entropy is actually depressing. You can't fight it. You can't not fight it. It just wins.

[-] WbrJr@lemmy.ml 43 points 6 months ago

So.. that's why I never tidy up my room. I'm just too smart!

[-] gamermanh@lemmy.dbzer0.com 24 points 6 months ago

Man, you humans are going to be really upset when you find the universal wall....

I mean uh....

Hey, how was the game last night amirite?

[-] Zorsith 22 points 6 months ago

Did you see that ludicrous display last night?

[-] FooBarrington@lemmy.world 12 points 6 months ago

What was Wenger thinking sending Walcott on that early?

Thing about Arsenal is they always try and walk it in

All we have to decide is what to do with the entropy that is given us.

[-] AngryCommieKender@lemmy.world 7 points 6 months ago

To quote The Star Child, "What, you haven't planned that far ahead?"

[-] oce@jlai.lu 5 points 6 months ago

Life is a temporary win over it, just enjoy it while you can.

[-] Dogs_cant_look_up@lemmy.world 106 points 6 months ago

One opening line that's always stuck with me is:

"The doctor said I was a paranoid schizophrenic. Well, he didn't actually say it, but we knew he was thinking it."

[-] gibmiser@lemmy.world 66 points 6 months ago

So... is Goldstein still around or did he...?

Don't worry, he's alive: His wiki page

We are all gas with a slightly denser particle distribution.

[-] hernanca@lemmy.world 22 points 6 months ago

We all are vast collections of harmonic oscillators.

Thank you for this, it was new to me

[-] umbrella@lemmy.ml 28 points 6 months ago

id want to kill myself too. just from the very little i know from computer stuff, imagine doing an entire semester

[-] AngryCommieKender@lemmy.world 15 points 6 months ago

Physics ≠ Computer Science

[-] RGB3x3@lemmy.world 29 points 6 months ago

Can't have computer science without physics.

[-] AngryCommieKender@lemmy.world 7 points 6 months ago

I'm not entirely sure of that. You can't have comp sci without algebra and potentially calculus. I could see a society that developed all three fields before they codified Physics

[-] force@lemmy.world 3 points 6 months ago

How do you have computer science without calculus? Calculus is literally necessary for computer science, otherwise it'd just be like... shitty statistics with a little programming

[-] Miaou@jlai.lu 7 points 6 months ago

Care to expand? Things like complexity theory and type theory, for example, have nothing to do with calculus

It would be inelegant as all fuck, but you could get away with just algebra, there are comp sci courses that only need algebra as the foundation.

[-] force@lemmy.world 2 points 6 months ago

as far as i can tell, the ones that do that are usually just programming courses with "computer science" slapped onto the title. but i havent exactly gone to many colleges so i don't have the experience to say so.

[-] loudWaterEnjoyer@lemmy.dbzer0.com 2 points 6 months ago

Do you really think people could make programmable microchips and processing units before they figured out physics?

[-] AngryCommieKender@lemmy.world 5 points 6 months ago* (last edited 6 months ago)

No, but mechanical computers existed before microchips. They just weren't terribly useful

[-] SkyezOpen@lemmy.world 4 points 6 months ago

Once I get my mechanical computer to run crysis we'll see who's laughing.

Sure you can. Physics is describing what is, computer science is building what could be

The two things require very little overlap. Even physics systems in video games don't use real physics - it just feels better when you fudge it

[-] Pulptastic@midwest.social 21 points 6 months ago

My favorite class in grad school. I absolutely loved deriving the laws of thermodynamics from first principles based the random motion of atoms. It was beautiful.

[-] Avg@lemm.ee 5 points 6 months ago

Is the grad school in the room now? Do you need help?

I don't know. I like Griffith's Quantum Mechanics which opens saying if you think you're starting to understand this stuff, you really haven't.

[-] normanwall@lemmy.world 2 points 6 months ago* (last edited 6 months ago)

Electrons, why do you behave differently when I'm looking at you?

[-] psmgx@lemmy.world 15 points 6 months ago

Weed out the riff-raff who can't hack it

[-] tate@lemmy.sdf.org 8 points 6 months ago

Boltzmann is "riff-raff" now?!? I get what you're going for, but c'mon.

[-] melpomenesclevage@lemm.ee 10 points 6 months ago

This is beautiful and I must study this subject now.

You know; so I have an excuse.

[-] astreus@lemmy.ml 9 points 6 months ago

I dunno, I usually open a textbook by turning over the front cover 🥁

[-] CluckN@lemmy.world 5 points 6 months ago

Why do we have a 🌫️ emoji instead of a cymbal? It would compliment the drum emoji so well.

[-] southsamurai@sh.itjust.works 8 points 6 months ago

Statistical mechanics is so fucking brutal \m/

[-] ornery_chemist@mander.xyz 12 points 6 months ago* (last edited 6 months ago)

...and then we take the partial derivative of the log of this infinite sum wrt molar volume to find that--

- Why?

Why what?

- helplessly gestures at the whiteboard

Oh, yeah, it's so the math works out later! Anyway, for small Θ, the derivative has a nice closed form that we can Tailor expand in f-

[-] Donkter@lemmy.world 15 points 6 months ago

Yeah lol, lots of physics and math was invented by multidisciplinary geniuses who saw equations that seemed to have no answer and said "oh yeah, this looks like a problem from biology that I've seen solved with this bit of fluid mechanics, and that problem can be solved with this complex trick from differential calculus. And you know, after we do that the whole system is starting to look like a circuit that uses properties from thermodynamics..."

Then your teacher and the textbook throws it on a white board and says "some smart dude figured out this was the way to solve this problem. It looks like this and it boils down to this equation. Don't ask questions."

[-] naevaTheRat@lemmy.dbzer0.com 7 points 6 months ago

There's a mechanics textbook called "there once was a classical theory" and it opens with:

There once was a classical theory Of which quantum disciples were leery. They said, “Why spend so long On a theory that’s wrong?” Well, it works for your everyday query!
