If theres anything that I took away from my 3 years of trying to get a physics degree before burning out on it around covid hit, its that like half of physics seems to be just figuring out what approximations you can safely make to turn something infeasibly complicated into something that can actually be worked out

That’s pretty much the same in most fields, especially in the engineering direction. Idealized gases are idealized, steel beams are assumed to have a certain stiffness just by convention, and your entire existence is represented by a bunch of form fields stored in a database somewhere.

Isn’t a lot of engineering basically applied physics though anyway? Just reversed, such that rather than studying or predicting how a physical system should behave, you’re trying to take what has been learned over time and use it to work backwards to create a system that exhibits desired behavior

In the sense, medicine is applied physics, just as everything else.
Thing is, you always break down a problem into just enough details to solve the problem. Not more. No physicist studying, say, airflow over the Atlantic will take quantum effects or relativistic effects into account. Magnetic fields are also ignored. Even clouds are surprisingly “low res” in most simulations.

Mathematics is the only true science.
Physics is applied mathematics.
Chemistry is applied physics.
Biology is applied chemistry.
Psychology is applied biology.
Sociology is applied psychology.
Et al.

I mean yeah. Insert the relevant XKCD here.
But in a more direct sense, medicine is applied chemistry. (With chemistry itself being applied physics.)

Are there non-circular cylinders or what does that even mean.
- pearsaltchocolatebar ( @pearsaltchocolatebar@discuss.online ) English7•5 months ago
Maybe they meant prism, since a cylinder is technically one.

Maybe what they’re trying to describe is a torus
- letsgo ( @letsgo@lemm.ee ) English5•5 months ago
No they’d only model a bull as a torus.

Now, how exactly is a penguin toroidal?
- letsgo ( @letsgo@lemm.ee ) English3•5 months ago
It has a single hole through its body from its mouth to its arsehole. IANAB but I think all other holes have at least a membrane between one end and the other. So it’s topologically equivalent to a teacup and a torus.

Imagine a donut-shaped penguin, love it! 😸

Maybe having halfspheres at the top and bottom? So more like a gas tank, less like a piece of sausage.
- sqw ( @sqw@lemmy.sdf.org ) English1•5 months ago
only thing i can figure is maybe technically you could call an ellipsoidal prism a cylinder also? seems like a stretch.
- jlow (he/him) ( @jlow@beehaw.org ) English1•5 months ago
Yeah, I also thought that there might be a cylinder based on a ellipse. Not very common but possible

So every first person player character is actually modeled after penguins ? This explains the head bobbing!

Yes, but a Mincrafter assumes that the penguin is a cylinder
