What is Computer Science? 

Oh boy, wait till you do it. Half the class in my uni failed

If any understand the the logic of taking gcf as remainder of now upto 0

why did you choose CS over IT or Software engineering

Thank you man!

You must be in job in be IT department. How is it going

I’m kinda thinking about going to nasa and I know they want computer science for astronauts. And even on the ground jobs.

You have to learn to think like a computer/ to think logically, so you can build things like apps with it.

Hahaahaha

Lmao

LOOOOOL

DONT GIVE UP YOU CAN DO IT

Same bro im trash at math

Binley Discrete maths is just like mathematical induction and progression and series which we learn at high school.

Which is what CS is about. He didnt do a video on programming, he did on CS.

think of it as philosophical mathematics. there is not half truth. it is Either 0 or 1 and from that simulate addition, subtraction or every other function in your computer. your computer doesn't subtract. it only adds ( component call a full adder) now how do you divide only be using addition and numbers.

Shubham Priyank you didn’t learn graph theory in high school bro

@@rban123 He probably did. The rest of us didn't.

is computer science hard? is it stressful and worth it?

I'm in high school so help me

@@sheezas7755 It is hard if you have no idea what you're doing. Though its worth it if you have a passion for coding. Computer science WILL NOT be for everyone, and you'll notice it when you start the major. But if you pull through its exciting and stressful all at the same time.

Yup same here.

I’m just getting and associates in computer science and hoping for the best

Thanks for the comment!

True

​@@zachstaris studying computer science difficult? Im not good in maths

Samee😭

But it's insightful. Now you know what to expect and how to prepare for CS.

Literally 🤣😭

If you like coding then you can do it. Dont let the math scare you

I'm a com sci graduate and now 10yrs working in the industry. I say don't let the math scare you. Any course is stressful. You'll learn it along the way. What's more exciting as a com sci student is that you can use programming to solve manual problems you have. For example, create a chat bot that will schedule your day.

Thanks man! Glad you found it.

I love low-level computer science

I like math but I didn't get it 😀

Ofc ur not gonna get it after first viewing but this stuff is all pretty simple if you watch some dedicated RU-vidrs and work through the problems with them. I’m pretty sure everything in this video was only pre-calc

Damn in France we do that in highschool like I already knew what he said and I'm not even done with HS (also although the video is good the explanation on the math portion was not very thorough but basically search euclidean theorem and proofs by induction I should understand it after a few hours of practice depending on how you're doing)

yeah keep that up. Big future ahead

Good luck!

@@batkhulegbazarragchaa5058 thank you

Good luck im 17 and ure pretty young and already looking at college stuff thats awesome fr fr we are moving to a world where everything will be digital

@@8eighttt. you're so right. 21st century is a century that is and will be different from the past centuries, extremely different. Kids right now should be taught about what is essential even if it means removing past topics every school has been used to teaching.

😂😂Bill probably did because it was too easy for him, wasting his time

bill gates went to college to become a lawyer

@@zeuskronos2018 he did 2 colleges, cs and law

None of what you said Computes.

are u still in that field how u doing?

palmchika13 Mary charry Not if you learned Algebra neerrrd

Jolt of Lightnin Doesn’t that mean your the nerd?

@@objectoriented3049 yes u do, ive learned induction before linear functions, so...

best of wishes and do your best!

Do it man

Yeah it's true

Same I need help

You can use the book Mathematics for Computer Science by F.Thomas Leighton

@@abdqs853 THANK YOU

You can do this, i believe in you.

@@wafflies8790 thank you♡

That's terrible. I hope all is best on your mathematics learning journey.

i'm in 8th grade now, i take everything back, i'd rather burn in the fiery pits of hell than go to another math class

@@kamillen4732 CRYINFG 💀💀💀

CS is really helpful if you want to get a job in UX.

Well you will still need calculus 1 through 3 and applied linear algebra so it isnt like discrete math is the only math

Sir, this is exactly the same case with me, i can see that you made this comment 9 months ago, can i know are doing fine in it? Or did you have some troubles in it. I want to take CS but i'm a little affraid that what if i don't perform good in it.

Or you can do software engineering which is like cs, but minus as much problem solving, they get payed good and I believe they don't take calculus courses

@@mr.meeseeks6549 thank you sir....

have you started your course yet??? ARE YOU COPING???

dark moon I was in the Middle East and moved to Canada at 12 too lol

middle east is ancient Capital of logic. Makes sense.

Ryan Bandler I’m thinking of majoring in Math and minoring in CS. Do you think this is a good idea?

thats like 2 years of classes

Mariano Ntrougka this is only relevant classes, not including all the general education and stuff. I have to take 4 writing classes, 2 physics classes, humanities etc. taking 5 of these classes at once would literally be suicide

@@rban123 no joke lol... considering it

nice! i’ve taken most of these as a CE major. i wish i went for CS instead.

TELL ME WHAT HAPPENED... did you?

Typical of Arab universities.

I think you'll run into a contradiction if you try to prove it because you'll have to completely by pass some rather important research.

@@aronflip9353 Didn't the Greeks only get down to atoms? Applying this same flaw in their logic to Plato's Republic one would be able to discern that the outer most extreme is beyond "god." Also, when Physics is applied into the argument you get that god is somehow energy which is something that contradicts the "teachings" of the church.

Bisssh what

BINGO!

shit i don't think i will survive this course then

Ahmad Noori that is so untrue, the maths in this video and in a CompSci degree is trivial compared to Olympiad Maths and a maths degree.

Pervy Sage exactly i dont even think the math for cs matches the math in olympiad math, more like olympiad physics

Bruh this is high school level math in some countries, Olympiad math takes INSANE levels of practice and knowledge

ポンスRuben mind = blown. Suddenly computer programming seems much more interesting

@@doodelay I know this is already old, but basically programming is telling a computer what to do step by step. And for your instructions to work, they need to make sense. So that is why one must understand and be good at logic to program well. The "math" of computer science is mostly logic and problem solving skills.

@@rambo3rd471 what do you mean by logic and problem solving skills? Do you know any books or youtut channels or a resource that teach?

@@JJoh4040 One way to define logic, is a science that studies the principles of correct reasoning. If you have good logic, your step by step instructions should work according to how you set up your program. If you have bad logic, your program will not accomplish what you want. While I do not have any books or online resources that I can think of off the top of my head, I can tell you, Google has everything. I would Google things like "intro to logic" or "how to develop problem solving skills," etc. If you are feeling a little daring, you could Google "Discrete math in computer science" or "Computer Science Math." Phrases like that. Discrete math is super hard to learn, but it's really helpful to develop problem solving skills. Like thinking outside the box.

@@JJoh4040 Brilliant.org is a good place.

Thank you! And yeah should've been one equal sign.

TonyZ some loops print out the first number with incrementing it, right?

Im new to programming myself but i've seen this in an introductory course of java script. i understand that i ++; is i = i + 1...but when talking about i == 0 i didn't quite understand as he mentioned something about quality.... so please can anyone clarify. +MajorPrep

i==0 can be used in this way: if (i==0){ do this code } So you check if i is equal to 0.

You're right, I just learned that in C++. You'd get an error or warning message if you write it as i==0.

FFS 😂

You got it! Thanks for the comment

Thank you!! So glad to hear this helped you.

So Computer Science and Informatics are different?

lucq No computer science and IT are different.... I think informatics is just another name for computer science

Rohan Sreelesh ok thx

konan obayan computer science = more logic/programming/AI/machine learning etc IT= hardware/setting up computers/servers/data centers

Karuska22ps i'm still a freshman but as far as i know, we focus more on softwares than hardware. I barely even hear our seniors doing hardware work. They're doing programming and such. Not setting up computers

SAMMMEEEEEEE

Sammee

Practice practice practice, that’s *all* it takes to get “good” at math

The secret of math is practice and never give up. U will love math.

Hey bro, did you take up CS? What happened? Are you doing fine in it? I want to take CS too, but my math isn't really good.

Fizs same I'm gonna grind and get my masters degree in computer science

Discrete math is fun!! And the proofs that you learn will be extremely important in your algorithm analysis course (if you have one) , where you have to proof algorithms efficiency and correctness

@@johnfedorov8089 sounds like a course i should definitely avoid

yeah tbh he explained the principle of proof by induction pretty well but he didn't really go in depth for how actually to proof it for n+1. If you really want to know how it works, there are plenty of videos on youtube. It's actually rather simple once you get the grip

FFS.😂 😂 😂

Thank you!

you got it!

Thanks! yeah schools will definitely differ so really depends, but I really liked those examples since they had applications.

Lol, this is literally how I think of sequences and series it's say more complied not thinking of it as a for loop for me.

The meat of Computer Science is still number theory...everything else is just Information Technology.

Brother please don't leave me hanging. I'm in school right now and I've to make a choice and I really like programming and planning to choose CS. what should I focus on? Math + Programming languages and what? Also how is the market/job availability? When and how many years did it take you to get the degree? Also any other advise would be warmly welcomed.

@@verysmartultrahuman939 I'm still in college but I've done research into this. But keep in mind you're getting perspective from a UK student. Yes, maths and programming is a decent chunk of the course. But I find there is more "theory" than anything else. I'm talking about how a computer *actually works*, and I think that's what you should focus on: System architecture Network Topologies Fetch execute cycle And programming and maths of course Market/Job stability seems to be great to be honest, even though the big companies are letting off a lot of people lately, there will only be a continuing demand for the skills in CS and smaller companies are hiring a lot of people. Not to mention start ups as well. In the UK, a computer science degree will take you 3 years if you get it right the first time. It is suggested you learn maths though, CS is embedded with lots of maths. I hope this was insightful :) look up a university curriculum for computer science to learn more and go from what the modules are on is my main advice. If a module is "Fundamentals of Programming", pick up a coding language like Python or Java as I'd suggest. Or something like AI, learn how AI works. That's my advice for you, good luck and let me know how it goes :))

@@ruben_9868 thanks a lot mate, another question, can I get a software developer job without getting the CS degree? Like can I get a coding certificate or something similar and get a decent job?

@@verysmartultrahuman939 Yes, yes you can, there's no one route to it. That being said, it's usually multiple certs that will be what you need, or bootcamps for example is often the other route people take. What matters most, as with most other fields, is experience. The education route is only recommended as it has a clear structure that is easier to follow, so you're more likely to stick to it because you have to. I don't know much about the other ways, but I heard bootcamps are good. So look up how to become a self taught programmer or professional.

@@ruben_9868 will do, thanks a lot for the tips. hope you enjoy the holidays.

Euclid? But that's 2,500 years old!...Ancient history! Ha!

Yeah once you learn one it's much easier to learn another!

Well, all of those languages are C-Based!

I'm sure they can accommodate his disability. Communication is important in any major. But I think he can just speak with the code he writes. Most of the time I am just explaining my logic in my code to my teammates but that could easily be replaced by me just inserting detailed comments in my code. I dont think speaking is necessary.

Nooooo

Hahaha...to hell with your negativity

omg i laughed so hard xD

King Ahmed fuck off

Jigsaw I think what he means is that get rid of your negative aspects and think positive

Yes bro in Chapter name," AP"

These particular questions are really easy, any IMO level student in the US shouldve solved it by 5th or 6th grade

Congrats,you must be a genius to get into Cal Tech
