Am I wrong in my concepts of these courses? I understand linear algebra is used in networking and graphics but is it really necessary to have a whole course devoted to matrices where 90% of the material is fucking useless? this honestly feels like the college is just taking money from me for a bullshit course in my major.

as a programmer will I ever need to know these fucking formulas from physics? will I ever need to know determinants and eigenvalues/vectors?

as some background I have taken advanced data structure courses, finite automata, and software engineering which are junior level and have never once seen anything from calculus, linear algebra, or physics used.

what the fuck is this shit?

Frankly, While I can see how certain kinds of programming wouldn't need physics knowledge...

Programming it's not just "Muh application development for some company" That's just a narrow part of the whole range of things you can do with computers, Just because you want to be a retard that makes application doesn't mean that the whole carreer should be focused in your preference, there's masters and doctorates for that... well, I really don't know if there's something like a master in "Look how good I'm in java"... I mean, programming is easy, and CompSci opens a lot of fields for you to continue in.. E.G robotics, ai, image processing, etc.


Many of these branches will require you to know a lot of math and be good with logic, because you want your program to run fast and efficiently. Some of these branches will require you to know physics.

the basic level you're whinning about is something that not only a CS should know, it's something that everyone should know. You should consider lucky that your field includes this knowledge.

Also, op, you're a retard, It really hurts me that people like you, without a pinch of passion decide to enter this field. It's perhaps because of people like you that nobody takes us seriously.

you've had a few people refute your opinion, but let me break it down a bit myself.

Linear mathematics help to describe to you in part how a binary computation functions. Physics on waveforms teaches you how the signal propagates in the physical circuit itself. Both are absolutely essential to the further knowledge of CompSci, and to dismiss them as nonessential ruins your basic understanding of the subject.

It really depends upon what you are going to do, but for the sake of getting a rounded look at the field, those courses are necessary. If you are going to work on a wireless data transfer project, you should know how the data is transmitted, what kind of noise it is likely to encounter, and how to correct for this noise. It is not entirely a hardware problem as the hardware still needs to be told what kind of signal it is looking for and from there the software will still have to implement proper corrections. It is entirely possible, and even likely, that you will never see this in your career, but this kind of things looks to be one of the bigger areas of CS research at the moment and so it is important to a proper CS education since it is meant to prepare you to do CS research, not to be a software engineer [that is what software engineering programs are for].

This is gibberish. You're hand-waving at stuff you don't understand.

Linear *algebra* can be useful for computer science, as just about any math can be, but is certainly not "absolutely essential":
http://www.mit.edu/~kepner/LAinCS.pdf
"Linear algebra is required in about half of the computer science curriculums and is optional or not required in the other half"

>Physics on waveforms teaches you how the signal propagates in the physical circuit itself. Both are absolutely essential to the further knowledge of CompSci

First, you're a computer science major, not a computer programming major. Being a science major means you need to have a broad general background in all the sciences. So yes, you need lots of math, and physics, and chemistry, and biology. In case you haven't figured it out yet, many of the interesting problems you work on in computer science come from those fields.

Linear algebra is a corner stone of understanding the math used in computer vision, much of AI/machine learning, and many optimization techniques. If you don't learn it formally, you'll have to pick it up informally along the way, which usually sucks. Good luck getting everything you need out of a linear programming course without it. Unless you were the type of child who taught themselves calculus when they were ten, and found an old textbook on the shelf when looking for a comic book, you'll have no chance of understanding anything non-trivial in computer vision if you don't learn it first.

I think the way you're trolling here reveals some actual confused ideas about CS, math, and game programming.

A lot of video game programmers are totally fucking elite applied mathematicians. SpaceX hired some game programmers to help them teach their rocket to land on its tailfeathers.

- Journalists write a title that involves "P=NP?!" and "quantum computers", sometimes with a relevant explanation somewhere, sometimes not,

- Since dumb readers don't read the article and just read the title anyway, they think P=NP for quantum computers: note, the sentence "P=NP for quantum computers" doesn't even mean anything, but they can't think something like "NP hard problems can be solved in polynomial time by quantum computers" because they simply don't understand the notions in that sentence,

- Other dumb people read that and keep repeating it since reading article titles on Google "confirms" everything.

What's the difference between an array or hash table and a vector or a matrix? There's not much. Your inability to do one is strongly related to the other, and it really makes you look like a pathetic programmer if you can't do something that's closely related.

Ways of thinking in other similar subjects translate over to others. You're thinking too small and not at the big picture. If you can solve certain problems in mathematics because you learned them, those same methods and ideas translate over to programming as well.

Computer Engineering and Computer Science have some overlap, but they take different approaches.

If you want to know how a computer works, take Computer Engineering. If you want to see what you can do with a computer, take Computer Science.

Computer Engineers learn maths so they can understand computers, Computer Scientists learn computers so they can understand maths(Not really, but that's what's meant to happen).

Computer Engineering = Software, Hardware, Some Electronics, Systems, Networking (Usually)
Computer Science = Maths, Algorithms, More maths

Which one is harder? Depends on where you go to study, depends on what your skills are.

I'm studying Electronic, Computer and Communications Engineering, so my course currently has a broader focus than most would.

Computer Engineers will deal with microcomputers and chips and stuff. A lot of control circuits and stuff that many would find boring.

I think it's a shame that Computer Science and Computer Engineering don't begin as a shared course in most colleges, few students understand the difference properly and many regret their decisions.

Keep doing shit-tier programming and call it CS all you want, it's only gonna make real computer scientists mock you ever more

To be fair I put <span class="math">graduate[/spoiler] CS in "Mid tier", maybe "Top tier" for certain sub-fields, but definitely never "God tier". This is for the graduate study of CS; undergrad CS is regrettably much closer to "shit tier" regardless of the quality of the university you look at.

Then you should go to a trade school for a fraction of the cost of university. Programming bootcamps are popping up like crazy:

Not really. Sadly many of those topics won't be seen by most CS undergrads and even if they are, it is usually at a very shallow level.

You're not look deep enough. A RC low pass filter in physics is exactly the same mathematically as an exponential moving average in code.

>Then you should go to a trade school
Nobody respects a trade school education in programming. Good programmers get tens or hundreds of times as much done as poor programmers, so nobody wants poor programmers.

Either self-educate (and do something awesome to prove you've got talent and skill) or go to college. CS, math, science (physics), or engineering (electrical, computer, or software) degrees are the only educational certifications that matter for programming jobs.

>Universities are solely for academic pursuits.
This is not just false, but ridiculous. College is the new high school. They let anyone in, they let anyone pass who shows up on time and is reasonably obedient (though not necessarily in every program), and if you don't get a college degree, you're shut out of most job opportunities. Some degrees are better than others, but any degree is better than nothing.

Trade school only works for narrow specializations, and only gets you good-paying jobs if you're especially talented or willing to work under dangerous conditions, in remote locations, or on a brutal schedule. And you're still fucked if there's a shift in the demand for your specialty, such as industry moving offshore or someone building a robot to do your job.

I recently needed to search 5 mb a bitstream with various values, altering a bitmap for every true value or value within a number of bit errors.

8 bit math and lots of array shifts in c# took over 60 seconds

Changed it to 64 bit unmanaged memory, bit shifted a cascade of the search term; 120 ms, which was adequate for my needs; could have kept going and done multi thread or better yet open cl and gotten it. A decent fpga could do the search in single digit clock cycles.

CS is math, not programming.

>> No.6535291

I actually hate that in our comp sci curriculum there weren't really any math like this and it's full of retarded manchildren who'll then bitch over the algorithms course because some of them don't even have basic understanding of math and only want to do programming (yeah, good luck with that).

Also feels like I'm left out of the real computer science and have somewhat wasted 5 years of my life (currently finishing my Master's degree), I feel so dumb sometimes, but I also really just want a programming job so I guess it's OK for that.

And yes, you do need a lot of linear algebra and eg. eigenvectors even just in 3D programming for example and a lot more with more industrial software, but you don't really need to understand the math behind them, just the basics and concepts, because the libraries always do the calculating for you. You'll never need to do this kind of a math tool method from a scratch.

OP, 15 year programmer here, let me be an ass:

Yes. of course those things are useful. Yes of course you can go an entire career without knowing them. I have used them in programming.


You wouldn't know because you're still in school. If you wanted to learn on your own you should have done that instead of going to school. You education is not going to convince me you're any good at programming either, so suck it up and finish your fucking class. The fact you can't seem to perform well on tasks that aren't immediately interesting to you is probably why when someone like me interviews you , you wont be given a job.

TLDR; suck it up everything is interesting in some way.
