How to count to 1000 on two hands

3328 ratings | 167589 views
Typically when we think of counting on two hands, we count up to 10, but fingers can contain much more information than that! This video shows how to think about counting in binary.

Hi, Can you say us what is the piano piece that we hear in the video? It is beautifull piece and I would like to play it. Thank you for the answer.

Optimize with gray code and you can avoid stressing so unequally three fingers

is it mathematically the optimized way to store the highest number of possible consecutive number ? (if we suppose that fingers have only 2 positions)

What if you made your other hand 32, 64, 128, 512, 1024?

You put down your whole hand and have a stored 31. I was trying to figure out a visual 31. Stumped me for far too long. I need sleep

Wait im starting to see why this may have been a dumb comment
Forget 69, 4 and 256 are the new taboo numbers.

Actually, if you're willing to do real acrobacy with your fingers, you may note that each of your fingers is made of three parts, each of which can be either open or closed. So each finger can meaningfully hold 3 bits not 1. That gives you 30 bits summing over the two hands. You can also add two bits which stem from the way you show your hands (which face). You now have 32 bits. Add to that 3 different combinations of the curvature of your wrist (straight, flexed to the inside, flexed to outside) for each of the hands. Now you have 3^2 * 2^32 = 4 294 967 305 different states you can encode which means that you can count more than have the population on earth. Getting your hands close together or far apart will give you yet another bit. So now if you are making a concert and invite every one on Earth to watch it, you will be able to count them all on your fingers and have plenty of room still. A bit too far fetched, but still theoretically possible. : )

The problem is whenever I show a number as 132 and they just think that I'm flipping them off...

Just a simple question, since every finger does contain difference value (not as usual every finger has value of 1), so how u do arithmetic operation, addition n substraction...let say 2+2, or 47 + 23 as example...

I learned this when I was a kid, and practiced it to the point where I could cycle through the numbers with either hand almost without thinking. Initially just as a novelty, but in adult life I have actually come across a lot of situations where it is really useful to be able to store 5-bit numbers physically without pen and paper: Counting elapsed times that run over midnight (or midday if you use a 12 hour clock) by reciting the names of the hours "8 o'clock, 9 o'clock ... 2 o'clock, 3 o'clock" while counting the hours with a hand. Recalling all the elements of a set and counting the elements that meet some criteria (like remembering who you invited to your birthday party and counting if they are vegetarian or if they don't drink alcohol).

2:09 correction - *With 10 fingers, you can count up to 2^9 - 1 = 511..*
Paulo Costa (7 months ago)
Your 10th finger is 2^9 since your 1st one is 2^0, so 2^10 - 1 using all your fingers is correct.

Positional counting marks an important step on from tallying or one-for-one counting, since it allows us to represent the many with a few, in this case 31 with 5, or even 1003 with 10. A simpler way in which fingers might have historically come to be used in positional counting and not just tallying involves hand prints (seen on cave walls round the world). On a flat surface put a small pebble between the thumb and forefinger of a hand print, that represents 1. Move it to between the forefinger and middle finger, that's 2. Move it on to between the middle and ring finger, that's 3. And between ring and pinkie is 4. To get 5 leave the pebble where it was and put a second pebble between thumb and forefinger again. Keep on moving and adding like this, and when all four gaps between fingers are occupied, we have 10. We're relying on the fact that 1+2+3+4=10. Instead of hand prints you can use any device with 4 obvious places or spaces, and the simplest I can think of is a cross-hair grid still with us as the + sign. (A 9-space grid is still with us as #.)

It's not binary type 16 gets hexadecimal 15 = the rest and otherwise you got it

Actually, you can count still higher if you can leva your finger in half. In this case, we could go all the way until 2*3^10 instead of 2^10. However, it is pretty hard to do what I said and, after counting until 54, my fingers began hurting a little.
Felipe Lorenzzon (8 months ago)
you coul also count until 2^11+2^10 if, when completed 2^10, you move an arbitrary finger to some side, as a reminder that you have 2^10. Don't leave it unfolded, just partially. When achieving more 2^10, open it compretely

As a low brass player in a symphony orchestra, I routinely need to count hundreds of bars of rests at a time. I actually taught myself this counting method, with the variation that the pointer finger is one, middle is two, and thumb is 16 (it's a more natural movement that way). There is the added bonus that most musical phrases are in powers of two (think of 8-bar or 16-bar phrases), so the big flips usually line up with a rehearsal mark. No more of this "am I at 30 or 35?" malarky.

The miners are interested in finding a nonce which will create a hash with certain characteristics. Lastly, they have to find a random value that they included in the header, which makes the computed hash over that header a value below a particular target. In other words, they do not have to agree to change the protocol. Though there are a few gold diggers attempting to fill their pockets and certain projects that aren`t viable and shouldn`t be encouraged in any way. For users running a complete node, it is a fairly painless procedure to upgrade the software to the newest version. The process of locating a new block to extend the blockchain is known as mining. Proof-of-Work systems utilize cryptographic hashing algorithms to create the action of mining a block a complicated computation. Our software is totally incompatible with altcoins. Changes and modifications to how that it works need to be approved by consensus and every CPU gets a vote. To start with, it`s essential to realize that hardware wallet users control entirely their private keys. Whether you`re bullish or bearish on Bitcoin Gold, you ought not lose your coins as a result of careless mistakes! On the 1 hand, it may result in making a coin that solves all the pending issues. There`s no currency or digital asset named Bitcoin Core. Bitcoin Cash increases the range of transactions that may be processed per block. You could send any quantity of money, any place in the Earth, almost at no cost. You`ve made some great money already on the market, but you want more. For a wealthy individual, BTC`s price premium may be viewed as a plus. For someone without lots of money, BCH`s low price may look like a great deal for Bitcoin. If you have some concerns about the worth of Bitcoin after all forks, you need to be ready for a drop. The distinction is that not all of these suffer the chain split. The primary problem is Bitcoin imposes a hard limit on the magnitude of a block, the location where transaction information becomes stored. The end result is many straightforward wallets, called SPV wallets and very commonly found on your phone, will be quite confused about which chain is Bitcoin. In Bitcoin, the most important reason is known as the network effect.
