Physics ≠ Computer Science

[–] [email protected] 27 points 5 months ago (2 children)

Can't have computer science without physics.

[–] [email protected] 7 points 5 months ago (2 children)

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

[–] [email protected] 1 points 5 months ago (2 children)

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

[–] [email protected] 7 points 5 months ago (1 children)

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

[–] [email protected] 1 points 5 months ago (1 children)

In general, a lot of the stuff computer science shares with data science uses calculus, a lot of the statistics too, but also visuals and modelling other sciences (e.g. simulations) use calculus heavily. I recall utilising vector calc a decent amount when working with Vulkan, for example

[–] [email protected] 1 points 5 months ago

Sounds like programming more than CS, in that case, fair enough. Also the linear algebra in computer graphics is, well, algebra, not calculus.

[–] [email protected] 2 points 5 months ago (1 children)

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.

[–] [email protected] 2 points 5 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.

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

[–] [email protected] 5 points 5 months ago* (last edited 5 months ago) (3 children)

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

[–] [email protected] 5 points 5 months ago

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

[–] [email protected] 1 points 5 months ago (1 children)

Wouldn't you also need to know physics in order to make a mechanical computer?

[–] [email protected] 2 points 5 months ago* (last edited 5 months ago)

Not necessarily. We had the theory of mechanical computers well before both calculus and physics.

[–] [email protected] -2 points 5 months ago (1 children)

What kind of argumentation is this? Are we talking about mechanical engineering or computer science? Please don't bent reality the way it fits your shape.

I know what mechanical computers are. But computer scientists will not be building them 'nor program them, it's not what computer science is about when you go to a university to study it.

[–] [email protected] 3 points 5 months ago

computer science teaches you the theories of computation which absolute starts with mechanical computers.

if one didn’t study Turing’s tape machine in their compsci program then they should demand their money back.

[–] [email protected] 3 points 5 months ago

I presented a hypothetical, and showed how it could work. You're the one insisting that there's only one way to do things. You're being Western Centric.

I'm well aware of what you study when you study computer science, I majored in that and Music Ed at Transylvania University.

[–] [email protected] 2 points 5 months ago

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
