I think this has made me understand how computers work. I could never understand how electricity could calculate anything. The trick is that they don't. It's just cleverly designed so that it will give the right answer to the input and then you scale it up and account for different types of input, but at the base all a computer is doing is adding and subtracting, which to a computer are really the same thing.

@MiniNinja2003

computers generally don't even have circuitry to subtract. they can use a thing called two's complement which allows them to subtract using only adding circuitry

@KnakuanaRka

Josh S (Not for the guy I’m replying directly to) In case you’re wondering about two’s complement, the equivalent in ten digits is doing a subtraction like 9-6 by doing 9+(1000-6)=9+994=1003. This is 1000 too high, but if you only can read the last three digits, the extra 1000 “overflows” and is removed, leaving the correct answer of 3.

@KnakuanaRka

@@JamesThompson-zu3bq There’s something known as “two’s complement” in binary; basically, IIRC, a string of all ones (like 1111) is generally the maximum value you can hold in a binary number of a certain length, which is one less than 2^the number of digits. So if you flip all the bits in a number, you get something that sums with the original to get all ones/the maximum; if you then add one, you get something that’s 2^digits - the original number, without any explicit subtraction. It’s a little more complicated with signed numbers, but the execution is the same. The equivalent in base 10 would be like starting with a number like 006, using a lookup table to subtract each digit from 9 (switch 0-9, 1-8, 2-7, 3-6, 4-5) to get 993, and adding one to get 994.

ideally, no. There are 2 ways of calculating the carrying bit that im aware of. One (ripple carry adder) is to wait for the previous calculation to finish so for example if you add 010 with 011 you add 0 and 1, you add the rightmost 0 and 1, you get a 1 and a carry of 0, then you add the middle 1, 1, and the carry 0, getting a 0 and carry 1, you then add 0 0 and 1 to get 1 to get 101. This is slow and seems to be what is done here. The faster way that requires more hardware but makes it faster (carry lookahead adder). Adding the abc with def, you do 3 calculations simultaneous 1. you add a, d, and [ (b and e) or ( (b xor e) and (c and f) ) ] to get x 2. you add b, e, and [ c and f ] to get y 3. you add c and f to get z in all 3 cases just assume 1+1=0 because we dont care about the carry bit, also in hindsight all three "add"'s probably should be replaced with "xor" for consistency, but you get the point. Your answer will be xyz. I'm sure you noticed while a lot of stuff is redone, the 2nd method will reach a result in 4 cycles. While the 1st seems more efficient, it takes significant more to reach the result. So no, +LapisSheepz, ideally, this is NOT how mc calcs work...right? At least a mixture after the size of the gate becomes a pain?

Also, in MC you have creative ways to make gates. With domino, you essentially make transistors, so...um...theres that too. I am aware that transistors are easy to make in MC; 1 piston blocking a signal would do it. i've just never seen anybody do it. Perhaps because it makes projects needlessly big since you can make most gates in comparable space?

Of course, if the lines are above and beyond the width of a domino, then the likely hood of tunneling decreases. Exactly the same thing is real circuit, probability and electron cloud.

No, it's more analogous to quantum tunneling or other causes of current leaking of current between 2 adjacent circuits. Electron migration refers to movement of the *conductor* being driven around by the electrons, and is best understood as a type of wear and tear, where sections of conductor can get worn away as the atoms forming them get shoved to other areas by the electron flow.

A concept that is vastly underestimated is motivation. In the beginning, I would suggest that motivation is the most important thing, even more important than content. Because - once you have built up a strong motivation, a foundation, a reason why you want to comprehend the whole topic - once you have that, all learning will work better. Because you always can link your current situation to your greater vision of motivation, and that is a strong driver. That video is for that reason: Building up motivation. I have watched much in the past, that does not teach that much content in time, what could have been done, taking another style. But all that added to my motivation and fascination of the topic.

This is how part of a computer works: the ALU (Arithmetic and Logic Unit). It's the bit of the CPU which adds. An ALU in a real computer, however, is able to add, subtract, and perform logical "bitwise" operations such as XOR or LSHIFT. Besides that, a modern computer also has a Processor, a Clock and Main Memory. So while this is certainly a computer, in that it can compute, it's not capable of running a program.

This is amazing. It explains the missing link I've had for years: how 0s and 1s work together to make bigger numbers.

I love re-watching this, but now I'm thinking it's time to break the record again and make it bigger! mostly because i really find pleasure in learning about the trouble shooting when it goes wrong

It was cool seeing the 3 bit version work, but in some ways it was even cooler seeing the 4 bit version not work, and how it didn't work.

I always love Matt and his optimistic ways of explaining a situation where something looks really bad. I think my favorite in that department is Grahm's number. Something along the lines of "While the range may seem huge, in the frame of reference of all numbers there are infinitely more outside the range than inside it. So we've pretty much nailed it"

Would love to see an update video on how much the domino computers have progressed in almost a decade.

"give us a round of applause anyway!" me omg

Now this whole domino show was quite amazing. I like seeing the inputs and outputs physically work. Thanks, fantastic.

The result proves that with transistors getting smaller every year this kind of problem would happen in a real computer...

Now that's a nice ripple counter! This is absolutely amazing! The half adders are beautifully constructed. No hard feelings that the 2's and 16's also fell. In modern electronic CPU's this is also a real problem, with electrons interacting on parrallel running data busses. The scale is towards the nanometers, but the effect is perfectly demonstrated. Really cool to see the large scale version be so accurate to it. Also, "The bit that keeps you awake at night" is a nice pun man ;)

You sir, whether or not your invention so well manifested by such dapper and trustworthy domino standers actually worked, are a wonderful and intimidatingly intelligent man. It's been great seeing you develop your own KZread Channel, as it always is when I watch these videos from your collegiate associates about Math and science in general. Merci.

Just discovered this, obviously. And I love the gate examples. Very good at showing not only how actual logic circuits work, but also at real problems! In your XOR gate, you demonstrate current leakage very well - when the signal goes "around" when it shouldn't.

This video made me cry tears of joy because I was baffled on how people like you can think of something out of the ordinary, and then pull it off, no matter how complex the task is! I probably would've never been able to figure out how the circuit failed in the second attempt, so hats off to you!

I think it was actually a good thing that your circuit was also able to accurately model what happens when you reduce the size of a real circuit. In my mind that makes it an even better demonstration than a perfect run would have been.

this is probably the best teacher for a integrated circuit / processor

wow... honestly loved this style of editing, super dynamic. never thought of seeing anything presented this way before

You mean a domino computer that will pass the Turing test? 0_o I can imagine a domino computer that would be indistinguishable from a human ;)

For some reason, I could not see Matt loving dominos so much at the beginning, but I really suits him

This was actually a really interesting and clear way to describe how computers work and what problems might occur

This *does* need to be on computerphile, along with a slightly more detailed explanation of how the dominoes are representing the action of electrons in silicon, germanium and the other materials. As Matt said, but could have emphasised even more, this Domino computer is a physical representation of ... a *physical* thing, actual things being knocked out to block pathways, etc.

Note that the way the gates are built in dominoes does not exactly represent the way they are built with semiconductors. In semiconductors, you are usually limited to two kinds of transistors. The XOR gate for example has eight transistors in a typical (CMOS) circuit, which are connected in a totally different way than the Dominoes. You could emulate the transistors with dominoes, but the gates would be three times as large or something like that.

How did you do that video tiling effect? It looks really nice!

Its actually a really good way of demonstrating logic gates. Props guys. not just for the concept, but for how much effort you put into this.

So our computer that was designed to add two numbers together gave an answer that required the user to add two numbers together. Genius!

Well by that logic a calculator that adds 134 + 273 to get 407 still requires us to add 3 number together. 4 * 10^2 + 0 * 10^1 + 7 * 10^0 = 400 + 70 + 3, Binary is the same just in base 2

The signal bleed and timing problems are things that actually happen in the circuits of a computer. Having to space things out a little bit to avoid leaks and making circuits that zig-zag to adjust the timing are actually steps that are taken when developing chips and circuit boards..

My first thought on announcement of which numbers will be added: "Why just decide to add 4 and 6? Why not ask a kid which numbers to add to prove it could do any of them?" Probable answer: "Some variations would be kinda lame to run. You want to have to do a calculation that looks reasonably cool in execution."

I think the first time Matt rolled dice or something, but it took a long time and was all a bit confused on camera, so I cut that sequence. For the second run we had somebody from the audience pick a random domino, which you can see at 15:30.

Glad you brought these bits down to words in a bytesized format. Hexsterical.

Watching this again a few years later, I can say that this video got me started with programming! Thanks for that Matt!!

A one-calculation computer. Nice XD

19:01 At least George Lucas in the background is happy.

Ok now you just need to build a little AI car that places the dominos based on a map, and then make a huge one, with 4 gigs of ram and a quad core processor. This is the future, who needs small computers, these are cooler.

the camera transitions in this video is so good! I watched it like three times because it was so fun to watch

18:00 - I was literally biting my knuckles over this to work. So heartbreaking at the end, but amazing stuff anyway!

This was way more interesting than Domino Day!

It's about the size of an iPhone 7 plus

incredibly clever and awesomely executed piece of work. love the presentation.

I love how he has such good humor about the parts that shouldn't have happened.

Really put hard work to do this.. Thank you for the team to make amazing content..

This is freaking awesome! Earlier I thought that this would be a stupid video regarding dominos, but the idea of using them as adders and gates is amazing !

This is actually incredible! It very nicely shows what exact difficulties are there engineering smaller and smaller silicon circuits. I would not be disappointed by the failure, rather the failure is actually the fun part on makings progress and as it was show for kids in museum that is something that young engineers need to see - not be afraid of failure.

Although you failed. The effect and result were still awesome. just watching the inputs flow as so fun. Congrats you guys

This is incredible! Not only did you create a calculator out of dominos, which is very awesome, but you gave me a better fundamental understanding of computers. Before watching this video, I had no idea how computers could work, but now it makes sense how very simple circuits (gates) can work together to create powerful calculators capable of out-performing even the brightest human. Thank you for this video.

My first computer, an Apple //e, its 6502 CPU, can not multiply nor divide. It only does one-byte addition, and subtraction, and various bit shifts. 8-bit data bus, and 16-bit address bus. Only 1 8-bit accumulator, and just 2 8-bit index registers. Yet when I ran AppleWorks on it, somehow it can multiply, divide, do y^x, do trigonometric functions, etc., and do all that to multiple bytes of accuracy. What gives? Well all of that stuff, can be derived in the form of iterations of additions and bit-shifts, so even its very limited CPU commands, are easily enough to compute just about anything. Although, not nearly as fast as modern computers can do it.

Next step: make a domino computer that can run minecraft. in said minecraft, build a redstone calculator that does division. ...am I skipping some steps?

I think it'd be interesting to calculate what the physical footprint would be in order to run a single frame of minecraft under optimal conditions (minimum system spec, no startup time). There's an answer, but I suspect it would be larger than the land area of the planet.

It may not even be possible. with a regular computer, you can switch a line on, then off, and then back on again. with a domino computer you can only switch a line on, and then never switch it off again.

To prevent signal leaks, you could put up barriers. Just saying. Yes more effort, but also more security.

Theoretically, you COULD build a domino calculator that did everything where the answer and the input numbers (question) were all less than 100. If you had a few square miles of free perfectly flat space you could do that. They need to invent ways to automatically make domino's stand up after being toppled, or have delay domino's that don't require turns and winding around things to add delay.

I like how after the cleanup you can see the chalk outlines of the xor gate intersections.

one of the best 20 minutes I've spent. Thank you.

what a great endeavour. .. so many concepts that are good analogies to real logic circuits. With dominoes!

This is one of the coolest things I've ever seen.
