[@Boltclick]

@@enjoykilian TLDR AT THE END Entrance exams are usually pretty easy. Universities care more about ruling out all the dumb people (relatively speaking) than isolating all the smart people, since universities generally send an application out to X amount of people. Let's say a university accepts 60% of applicants. It doesn't matter if the applicant is in the top 1 percentile, or they're at the 50th percentile (maybe for cost reduction things, but in places with free uni, that's irrelevant, and also most scholarships aren't exam based), they've made it in. As a result, there's no need to make the exam particularly difficult, as you don't need to segregate people into tiers of aptitude, and instead just want a pass/fail system. Either you're good enough, or you're not: it's not a particularly high bar. Now, final exams on the other hand are much more difficult because you're expected to know all the content of a class, and are thus expected to be "smart" (also, finals often affect your GPA or whatever your country's equivalent is). However, entrance exams are just meant to make sure you're not dumber than the university wants, not that you're smart. Additionally, many university courses are entry level--- after all, university is a place to learn, not to work (academia doesn't count because you make like minimum wage there). For example, I can take French I at my university: a course with a syllabus that literal 10 year olds could do with the same proficiency as a university student. Similarly, a 7 year old could easily understand "Intro to Programming," because it's another into level course. I don't know what prestige of a university they're going to, but their entrance exam might cover a very wide range of topics at a shallow level, rather than a deep level of a few topics. There's no guarantee they're going to a STEM school, but that doesn't mean the exam won't have STEM related question, even if they don't intend to take STEM classes in the future. For example, in the US, the SAT and ACT standardized exams are stand-ins for entrance exams (since most US schools discontinued classical entrance exams). Even if you go to a pure STEM school like MIT, MIT will pay attention to how you did on the SAT and ACT, which are 50% English based. Similarly, if you intend to major in literature, your collage will still look at your SAT and ACT scores, which, again, are 50% STEM. Collages want you to know a little bit of everything going in. TL;DR: Entrance exams are meant to be easy and rule out dumb people rather than find smart people (THESE TERMS ARE RELATIVE, NOT SAYING THE PEOPLE WHO FAIL ARE DUMB). Also, entrance exams often cover a wide range of topics at a shallow level (ranging for Science to Math to History to Language to many more subjects), rather than a few topics at a deeper level, because universities want everyone to have a base level understanding of everything going in: knowing everything about one subject means nothing if you can't relate it to everything else

Oof, this is definitely way smarter than what I did lmao I had a bunch of AND gates that literally produced all of the possible decimals as separate redstone lines. Made the 7 segment section simpler cause you can just place torches in a specific order manually for each possible output, but is ultimately unsustainable if you want to add anything bigger than 9 + 9.

[@MrFiveHimself]

I mean not really? it *sounds* like you used a ROM which would definitely be the more efficient method. Seeing as you built a calculator already and by your own wording, im gonna go ahead and assume you know what a rom is. Ive build a few computers before and in most scenarios regarding 7 segment displays, a rom is perfect. Using traditional binary operations is soooooooo much slower and way larger for (and i can not stress this enough) THIS SPECIFIC GOAL. Roms have a tendency to get big quick when you add more inputs and need more outputs which dramatically slows down speed. Regarding the limited output amount, ive noticed that the best way to go about it is to do the conversions sequentially. just map the locations you want the redstone to arrive at, make a simple counter, and only let the the data travel to the display with the corresponding count (i.e. if the counter is at 6, input the data to 7 segment display number 6). Then just slap an RS Nor latch before every single segment of the 7 segment display and have the display reset when a new calculation is processed. Note that the girl in the video used a BCD converter in their calculator to use multiple decimal values. If you want to do this as well, you're gonna have to do it too. Im not gonna try and explain how but there are many guides online. I wish you best of luck in improving your calculator!

[@CensoredUsername_]

Nah, the rom decoder method for 7 segment decoder is much more efficient than the presented logic gate trees. What you did was faster for single digits. And for multiple digits in decimal logic you just want to do binary coded decimal, then you can just reuse that decoder for each 4 bits.

[@CensoredUsername_]

You aren't, that is indeed just A xor B xor C, and that's also just how anyone would implement it. The later section offers also two different layouts for the xor gate funnily enough. A xor B == (A or B) and not (A and B) == (A and not B) or (B and not A) == (A and not (A and B) or (B and not (A and B)) to just offer a few versions. When using redstone logic, almost anyone would use the (A and not B) or (B and not A) variant for simple repeater torch logic. It has the lowest delay, and is generally more compact. The 7-segment display logic gate layouts are also silly. Nobody lays those out as separate logic gate trees. You'd just use a 10x7 decoder array instead. It's significantly more compact, and that is what we all did even 10 years ago. Would've been much more interesting to see that concept explained.

There's a bit of an error around 7:15 - the order of the columns in the Karnaugh map is wrong. The columns and rows are supposed to be ordered with Grey codes, which is to say that only one bit should flip between adjacent columns or rows, which means you can't have 00 and 11 beside each other. A good order would be 00 01 11 10. In this particular instance, it doesn't make much of a difference, but getting it wrong can lead to suboptimal groupings.

And the fact that not a single actual redstone was shown (only the 2d perspectives were shown) was kinda disappointing. Still though, this is some amazingly good editing. I love the parts where the lamps turn on and off on the path of the logic gates. That's a lot of explanations too, must have taken a long time to research all of that, very impressive.

Given the title of the video, making the content about how binary circuits work fits very well. Plenty of content about how to implement all of the circuits discussed.

To be fair, there is a pretty significant divide between the computational and practical aspects of redstone. Just like how real life electronics are far more complicated than the computational logic they are driving, so too is redstone more multi-faceted than the circuits here. Minecraft redstone just happens to be a great educational analogue for computational circuitry and demonstrating how discrete math can be implemented. I imagine that for many redstone engineers, there is a difference in skill and knowledge between the "engineering" side making use of BUD power and zero-tick clocks, and the "computational" side scaling huge systems of logic to accomplish complex tasks. Given that Minecraft redstone is both turing-complete and has so much depth in its underlying mechanics, everyone should know a little bit about both circuit logic and gameplay mechanics to optimize their builds. At the very least, redstone is a great educational tool

i think the point of this video isnt how the redstone works, and he does show you exactly how to make each one. making a computer in minecraft is like 99% working out the circuits and planning and 1% actually building it. all this information is necessary to understand how its possible

[@Cow-Moth-With-A-CRT-Head]

Holy heck, this format made me actually finally understand how these dang things work. Thank you!!

This person has such a simmilar voice and way of talking to Pastra and it's fucking with my brain.

That was an amazing video and the "OMG" at the end slammed me face first back into the tile floor of my highschool AP programming class when the schools antivirus incorrectly identified my C++ program for "life" as a virus and deleted it. My fault for not having a backup but still... Exact same "OMG"!!! Keep up the amazing productions!

there is an insane amount of lack of empathy, transphobia, misogyny in this comments section. im sorry

[@Rascallx]

was wondering why bro sounded like smeagol from lord of the rings, thanks for enlightening me as to why that is. it makes sense now

I love the analysis of the function. Visualization was top notch!

@@delimiter2886 thanks. Maths use to show patterns, ask Newton about that

Excellent video Ellie! Glad I discovered your channel

[@justsomejerseydevilwithint4606]

It's all just computational mathematics.

[@irmadbro]

The fact that you completely skipped over the conversions between bcd and binary is genuinely the best part of this video. I now want to go back to fiddling with logic gates again. Thanks my friend. I will be cursing your name in a month

who?

I’m a 3rd year electrical engineering student at a highly regarded engineering school, and this video just helped me understand ripple carry adders more intuitively than its every been explained to me before.

I didn't know Chris Chan had a KZbin account dedicated to math and science

[@Anagusame]

I love how passionately you talk about this!

[@zh9664]

the voice is so hard to listen to

[@Rayadix]

Juste wow First the way of making a "simple" calculator And the editing of thé video IS grrreeeeaaaaat gosh it's wonderful.

[@blockshift758]

That part i hate here is you sould like you're speaking in a documentary video but constantly in that big reveal voice. Its not bad but being in that tone constantly i personally find annoying. Also its still a net positive for the redstone community.

[@chrispysaid]

...what?

[@Zombienekers]

@@chrispysaid What OP is saying is that OOP sounds like they're always finishing a sentence. Yknow like how people raise their voices when they end a sentence? That applies throughout this whole video.

[@DaWhiteKidMike]

This was an incredible video. Bravo chap, bravo

[@comm_gt]

The voice kinda sounds like you're constantly on the verge of crying but never get there

[@Shamus-x7k]

I must say, I'm only 45 sec. In, yet I already know where this is headed and albeit I know the answer I like the enthusiasm you bring to the idea. In good faith I will finish the video. Cheers Boolean Algebra is fun...

[@rafaelmocochinskifreitas9016]

Watched this a few months ago, this video was all but a confusion and abstraction for me. Now, I'm taking a Digital Electronics grade this semester and this video helped me to jumpstart some of the concepts very well!

[@angeldude101]

It pains me to see how unoptimized that adder is. The second half of the ones digit is literally just a second xor gate, but the video never gave an indication that that was the case. In addition, both the ones digit and twos digit had identical xor gated that don't seem to have been merged. Technically, a decoder is just a bagillion gates. A BCD to 7-segment converter is 10 parallel 4-input AND gates, followed by 7 parallel 10-input OR gates. Unfortunately, propagation delay tends to be more important than the number of components, especially in redstone, so such a solution, while far more boring than the shown solution, is usually preferred. That's a lot of effort to convert between decimal and binary, and programmers tend to be lazy, engineers tend to be cheapskates, and neither tends to be willing to put in that extra work to make those converters, and so will just leave things in binary, or if you're lucky they'll work in hexadecimal since it doesn't need full division in order to convert to and from binary.

[@spacechemsol4288]

Make it work, make it right, make it fast. Optimization comes when you have working system and does not really add to the overall approach. So not having that step isnt a big deal.

[@germangonzalez4347]

Awesome video. Coding is a magical, limitless logic puzzle and it's so cool to watch someone work it out on something as silly as minecraft

[@autumnwinter3639]

Wanted a cool video on redstone computers, ears bombarded by the disturbing sound of a man trying and failing to sound like a little girl.

[@hairyarmenian]

Also, very weak introduction. Computer simulating consciousness? Please do me a favor and begin to write the closing chapter to your life. You have failed at being a man, you have abandoned your life's biological duty.

[@Commander_Chopper]

professional software dev here: This is an extremely solid and low bar introduction to boolean logic. Great stuff!

[@danielsmokesmids]

i know this is rude and i probably could express this in a nicer way but the way you talk is really hard to listen to. im interested in what you have to say but the voice is throwing me off

nvm i got used to it im sorry😭

This is a fantastic video. I absolutely love how you presented the redstone gates visually with the redstone lamps, it was very fun to watch! Your passion is clear from your narration in these videos. I look forward to your next upload!
