I seem to remember from one episode on History channel of the aliens or something that somewhere the 12 base counting was used and made sense because you count with your thumb the inner parts of your fingers whete each has 3 parts.
I think the Old Egyptians did that.
There are many different bases around the world, to think all of humanity uses base 10 because we have 10 fingers is wrong. You can count with the spaces between the fingers (base 8) for example
Never thought about using that, but yeah, even base 8 makes sense.
Dammit dad. Fine, take it (the upvote that is)
Dozen't it, thought?
Yes, really bizarro
lol. Topical
Only 10 fingers.
How does it get activated? Tied to the real thumb?
I haven't tried it but it has a couple foot sensors that are used to control it. Probably more preferable if there was some way to link it into the nervous system without surgery, but lacking that it's going to piggyback on some other fine motor control.
You control it with your feet? That seems counter-intuitive ngl.
It's apparently like driving a car or riding a bike or swinging a hammer, there's a small learning curve but with a little practice it's overcome pretty quickly and feels like a natural extension of yourself. But yeah given a preference I'd probably want to try tying it to wrist or hand movements for practicality.
Yeah I cannot imagine it being easy to use when standing or walking.
12 knuckles on your fingers, use your thumb to count em.
Binary wins though, learn to read it and you can count uo to 2^10. Well, sort of. Ring fingers and little fingers ruin it for me.
Someone else who knows how to finger count in base-12 and binary!
I think the binary one I learned as a joke, show someone they are number four.
The base-12 was an explanation for how the ancient Sumerians finger counted, using the other hand's fingers for groups of 12, leading to base 60 (5×12).
I have the same problem with binary counting practically though, and using a modified Sumerian system (both hands to 12) gets you to 144, which is plenty for anything where finger counting is actually useful.
One other thing, I use the finger bones rather than the knuckles, little easier but same idea.
If only we could combine the two and get to 2^12... Sadly, this would require 12 thumbs.
Ooh, actually you can get to 2^8 without worrying about those pesky tendon issues by putting your fingertips against your thumb instead of trying to extend your fingers... Hmmm... Maybe we can even go to 2^10 this way by incorporating knuckles. Might lose some time today figuring out more hand counting systems. I wonder if anything higher than 2^10 is possible...
Some might say it's giving finger counting too much thought, others might say it's a tangent too serious for dad jokes, I say… the efficiency gains seem to come from a change in technique for how a count is stored.
Base-10 finger counting technique just accumulates, the number of fingers held up is the count.
Base-12 uses a pointer (your thumb) to point to a value (a knuckles or finger segment).
Base-2 uses a finger up or down to show a place value as one or zero.
You could tattoo numbers on your forearm so all five fingers from your other hand could point to a value for up to five more places to point.
(Western) base-10 needs two hands. Base-12 is one-handed. (There's a base-10 system used in China that's one-handed, mind. Or, rather, it's one-handed until you reach 10.)
Also some maths operations can be done fairly easily (like division) with the base-12 finger-counting system.
Base 10 on your hands is really base 1. Every finger is either 0 or 1 and we just count them! Base 12 we do have 12 positions each representing a digit, and two potential digits from our hands.
Binary is so much more efficient because you have 10 digits, just like in base 1, but you use them more efficiently.
The next logical step is trinary, if we can incorporate enough fingers it would go higher than binary. Wikipedia suggests three positions of your fingers - up, down, and somewhere in between, or folded - but I'd be surprised if anyone can realistically do that with all their fingers. However, using four fingers on each hand and pointing them at different knuckles/the tip of your thumb gets you 8 digits of base 4 (including not pointing at the thumb at all as 0).... And actually doesn't tangle your fingers up too bad.
Skill issue
Binary finger counting is a pain in the ass, though. Too complicated for most people.
Once you get the pattern in your head it's pretty easy to remember where to go. The tricky part is actually holding up your ring finger on its own.
There are a great number of ways you can count on fingers. You can easily support base 4, base 5, base 8, base 10, base 12, base 16, base 19, and even higher (144, say) with finger counting. There's nothing particularly "natural" about 10.
You forgot the toes.
And for our male comrades, there's one extra ;)
Either way you'd need to make some... Edits... For the numbers to line up properly.
Or anyone from Norfolk
