What is Computer Science? (Part 2: Algorithms, Computation, and more)

[@minh5044]

Computer scientists really are just mathematicians who are desired in the workforce.

[@oxox491]

Computer science is a branch of mathematics, it just became a whole major to itself because it is very applicable in a specific industry.

[@mangomanlassi7779]

imo computer science is a combination of mathematics and engineering

[@jadedplover1851]

My course also had a non-elective continuous mathematics unit alongside the discrete math one. Continuous math is still very important and will come up often in comp sci particularly in graphical programming or when trying to emulate real world physics.

[@sitrakaforler8696]

YES hahah

[@breggsgonzales2924]

This kind of math is very interesting for me. Never really favored math but math problems like these just makes my brain work!

[@TheNayalin]

This was very helpful! I was considering switching my intended major (Neuroscience) to computer science because I was interested in programming-this video helped me make a better decision to just keep my major and maybe do CS as a minor. CS as a major has TOO MUCH MATH that I have no interest, or patience, to learn. Thank you!

Thanks for the comment! So glad to hear it helped.

For those who would like to know how much math classes you have to take, I sum my case up here. (Well it got longer than I expected.) So in the first four semester you have about 50% mathrelated classes. We need to take Discrete Mathematics, Linear Algebra for CS, Analysis for CS, Mathematical Logic with are mostly pure mathematic, and there are classes that are theoretical and are mathematical too but a bit different: computability and complexity, formal systems and automation but there are also interesting classes, if you are not that much into math, like programming, computer engineering, which was mostly like an introduction to electrical engineering, operating system and systemsoftware, mostly about scheduling but we learned a bit C and bash, databases and information systems, software engineering and we had a lab where we wrote our own OS. Well, this is my case here in Aachen, Germany, where it gives you a good basis in the beginning of the Bachelor and later you can choose on what you want to specify on. I can't tell you much about what happens later as I only started studying two years ago. I have to tell you it is not easy and a whole another dimension than high school, but if you learn enough, I mean learn for real, not just two hours a day after the lectures, you can make it. But I guess how difficult it is, is really different depending on the country and city, so I can't tell how hard it is somewhere else. Atleast here you won't get much holidays, haha. But I hope it gets paid off later and studying could be enjoying too, if you are getting used to it after a while. But I guess in the beginning most people will be shocked of the maths, good luck.

"Calculus comes very rarely" Not so sure about that. I'm a CS major and so far I've gone through 4 semesters of Calculus, that's 2 years of learning new ways to solve differential equations. Then had 2 semesters of fourier analysis, granted some of it was applied to signals and systems. Also went through probability and statistics to then learn about stochastic processes, which again is basically calculus, as well as optimisation (which, again, is a mix of calculus and linear algebra) for machine learning. And in the following semesters, I'll have to take classes in signal processing which again, is nothing but calculus for the most part. CS is just Math, not Math for its own sake like Math majors do, but Math needed by the industry. People who were looking forward to code 24/7 are the ones who struggle now, also CS students are not that good at programming for the most part, I mean we're obviously better than every other majors in the purely scientific field, but it's definitely not what we excel at: we're better at problem solving involving logic, information, data structures, graphs, and other kinds of discrete objects, but the coding part of it will most likely be left as an exercise to the technicians you will be working with, who probably know how to code better than you.

[@INVALIDZEROTheTitSucker69]

How hard is it to do more than 1 major? (I am just in my last school year and am close to doing my final school exams before graduating from my school and was curious about what I could do after school and wondered about the possibility of studying more than one thing if possible so that's why I am asking. And of course, you can just choose to not respond)

[@HaI0gen]

This is a decent introduction to the theoretical foundations of computer science. Two other fundamental topics are programming languages/compilers, and operating systems. Every CS major will take some classes on those topics.

I got to be honest. I was terrible at math in high school. Could barely pass each grade. I am 5 years out of high school and I have been feeling the urge to take up something like computer science. I am worried that I might still not be very good at math although I have learned a lot about myself since high school and one thing I have learned is that I can do anything I set my mind too.

Computer scientists are researchers in Computer science like AI researchers ( who will have PhDs) just like phyiscs majors aren't called Physicists (a phd is needed), you need PhD and research to be called one So don't go into CS unless u wannabe a researcher.
