Map of Computer Science

The field of computer science summarised. Learn more at this video's sponsor https://brilliant.org/dos Computer science is the subject that studies what computers can do and investigates the best ways you can solve the problems of the world with them. It is a huge field overlapping pure mathematics, engineering and many other scientific disciplines. In this video I summarise as much of the subject as I can and show how the areas are related to each other. A couple of notes on this video: 1. Some people have commented that I should have included computer security alongside hacking, and I completely agree, that was an oversight on my part. Apologies to all the computer security professionals, and thanks for all the hard work! 2. I also failed to mention interpreters alongside compilers in the complier section. Again, I’m kicking myself because of course this is an important concept for people to hear about. Also the layers of languages being compiled to other languages is overly convoluted, in practice it is more simple than this. I guess I should have picked one simple example. 3. NP-complete problems are possible to solve, they just become very difficult to solve very quickly as they get bigger. When I said NP-complete and then "impossible to solve", I meant that the large NP-complete problems that industry is interested in solving were thought to be practically impossible to solve.

Hey thanks for all the comments! Yes I agree that I should have added in computer security alongside hacking. It is a huge and important field so I regret leaving it off. And I should also have mentioned interpreters along with compilers as this is an important concept, especially having coded a fair amount of python I have no excuses. I added a couple of notes in the video description. Thanks for pointing these omissions out, and thanks for all the words of encouragement as well. I was trying something new with the graphic design on this one, trying to match the look to the subject matter and I think it worked out well.

Hello, i just bought a poster from you in the small size. It's an awesome poster and i was wondering if you had a good frame for it. I';m just not sure if 23.2" x 16.4" is a standard size. I keep seeing 23" x 16" and am not sure if that would work

Computers are getting smarter and smarter but still humans brains are way above as computers can't imagine all different sort of things like the human brains can do therefore we must find a way to make both comunicate way faster and more efficient than a keyword or mouse or a monitor it should be something directly accessed by our brain like a new organ in our body

One quick issue, Computer engineering is the study of how electricity forms digital circuits to carry out computations this has roots in physics and electrical engineering. Most of the things you put into Engineering falls under Information Technology.

I object to the use of the term "hacking". "Cracking" (as in "safe cracking)" is more accurate. Hacking refers to poor quality items produced by amateurs.

Heck no, GPUs aren't just for graphics. There is billions worth data centers run on NVidia GPUs. Also Nvidia GPUs revolutionized AI. That's the only reason why we have such advanced almost Skynet grade AI these days. The lack of processing power held us back. It wasn't the lack of neural network algorithms. Nvidia Tensor Cores are recent addition to supercharge AI. Even gaming GPU like the recent Turing Geforce got those cores. No, not AI for game NPC only. But for denoising ray traced images, and for upscaling in real time. I think before IBM's and Intel's neuro morphic chips aren't out, Nvidia will remain king with AI.

1:06 no, quantum computers are still equivalent to Turing machines. They can solve exactly the same problems TMs can, but sometimes they can do it faster. Not all Turing-equivalent systems need to have the same complexity characteristics (for example, addition is O(n) in Brainf*ck but O(log n) in most sane programming languages). Also, modern computers don't really function like Turing Machines. Sure, they have a memory tape, but there's no concept of a "head". You dereference any pointer, anywhere; you don't need to meticulously move the tape head over to a region of memory in order to read or write to it. That would be unbelievably inefficient. Moreover, most modern programming languages are far closer to the lambda calculus (even if they don't have lambdas). Turing machines have no concept of a "function" or an "expression". There's no modularity, in the sense that you can't write code that can be reused later without modification. Writing programs on a Turing machine is painful. Writing programs in the lambda calculus is actually relatively pleasant. I don't think any Turing-equivalent system can be called "fundamental." The lambda calculus is the best model for most programming languages, but the lambda calculus is hard to actually simulate. When you're trying to prove a system Turing complete, it's best to target an extremely minimal system, such as a Minsky register machine, or bitwise cyclic tag, or the SK combinator calculus.

I just can’t understand how a piece of metal can ’think’...
Alex Beserra (1 month ago)
They "think" by the use of transistors. Without entering into details they are basically tiny, really tiny eletronic switches that control the way current flows just by positioning them and their wires together in logical and well defined positions, making logic gates. Thus it will be possible to represent the logic values true and false either when the current flows or not. The computer is a huge calculator and it calculates in binary base system thanks to the states of transistors (true/false, 0 1). That's basically how all eletronics work: doing calculations, even to represent colors, letters, images, videos, audios, everything. It's impossible to explain it here because it is a really complex topic. To understand it well you got to study base two system, boolean algebra, integrated circuits, computer architecture and a lot of other things.
Mollof (1 month ago)
But how is it possible to implenent that into the items. Yeah, with coding ofc, but it's just hard to explaine what I don't ujderstand
Winston Mcgee (1 month ago)
it's not the metal, but the software. in a nutshell, you "teach" computers by feeding them with data, and depending on your instructions or algorithms, they learn and train from it by learning the patterns and minimizing their errors or mistakes so that the next time you show them a real different but similar pattern, they would learn to recognize or classify them.

Hacking is not about craking, its about creating things with passion and altruistic values, like brainstorming, or creating open source brains or linux, you have a misconception there.

Learning Computer science is better than Software engineering.
Yes, but basics aren't enough for "good" programmer.

No,if you study computer science, software engineering is very easy for you,it will be like entertainment.

To all of you with a interest in computer science and programming... I just realized how important programming and computers are going to be in the future, and thus I concluded, that I‘m going to learn how to programm. But honestly... I don‘t know that much about computer science, so I wanted to ask all of you: Why are you so passionate about computer science? Where should I start learning? What motivates you to keep learning? What cool stuff can you do (with even small acchievements)? How did your knowledge about Computers, programming etc. change your world view? I‘m thankful for every comment, all advise and would love to understand more about this topic. Feel free to share your passion :D Thanks in advance

how to read programming books: First, don’t skip the introduction because most of these books describes how a language effects or deal with hardware or how the compiler works. second, work every instruction the book command you to do because it will definitely help you otherwise won’t make sense(why the author put it there in the first place).Third, go to every source the book command you to got to because it will gives you more knowledge about some subject; by the way try this android app, it helps you extract a URL without write it by hand ( https://play.google.com/store/apps/details?id=text.ocr.mostafa.extracturl ).Fourth, solve every problem the book gives you, it will teach you how to use what you learned and gives you more experience. I HOPE THAT HELPED.

This is why sometimes a computer science degree is better than self teaching. These "bootcamps" usually only teach you the bare minimum for simple fields like web development. Self teaching for web development is a good idea, self teaching for AI: not so much.
