FYI a normal human can count to 31 on one hand using binary.
and China has well established hand gesture for 0-9 on one hand.
and even if you don’t know that, it’s quite easy to count to 12 using finger segments.
I have a well-established hand gesture for 1!
Impressive! In binary with one Hand you cant even count to 5!
You should see my binary hand gesture for 4!
I chuckled at 4 (my favorite number!) when I just tried out counting to 31
China? The 0 to 9 single handed gestures are used for a lot outside of that. Like divers use that, all kinds of trades, and the military.
Ah, I guess that’s one specific method. Several have existed across many cultures and professions.
Use ternary. Up, down, half bent. I think that gets you to 242
FYI anyone counting in binary on their hand(s) is decidedly not a normal human.
Wait… what
Rather than assigning each finger the same value of 1, assign them values of 1, 2, 4, 8, and 16. Then there’s some combination of fingers that can represent any value from 0 to 1+2+4+8+16=31. It’s like using digits to count instead of tally marks.
32 different combinations.
2⁵ = 32.
It’s 2026. You can write the top voted nerd joke and still be dead wrong about the math. We’re in the “You’re absolutely right” era now.
You can count to 14 with just the segments of one hand which makes my head hurt less than bit flags
Sumerians, 4-5000ya counted to 12 on one hand. 4 fingers with 3 sections each with the thumb as a pointer. Then the other hand counted off 5x12 which gave us yhe hexadecimal system of counting which is still in use today.
I can count to 31 in one hand in binary. It’s not a super useful skill, but it’s won me a bar bet more than once.
I want to go to the kinds of bars where counting in binary wins bets. Most of the time it’s things like “open a beer bottle with your eye socket”.
The trick is to be the one making the bets and to word them in a way that makes the losing side sound like the winning side (or one that generates enough curiosity about how you can actually do it that people accept the bet knowing you probably have a trick).
If you add things like arm position and rotation, you can add even more bits. Using 4 arm positions and 2 rotations, you can get a full byte of data with one hand.
Sexagesimal, hexadecimal is base 16. You could say that simply improving on mathematics lead to the hexadecimal system eventually but they did not create the hexadecimal system.
Is this something that can be easily taught? Could you teach us how to do this?
Use your thumb to “point” (touch) a section of your index finger, middle finger, ring finger, pinky…now move up a section of the finger.
Tada you learned it.
The other hand goes 1 when you maxed out your finger sections, then 2 when you do it again where one equals 12 and 2 equals 24 etc.
There’s really nothing to it, no research needed…just attempt to mimic what the comment describes and you’re there.
I don’t get it 😅

On one hand
The joke is he had 8 fingers, which is a mutation from living near Chornobyl.
lol, I guess I was wrong then - I was about to say that OP seems to think the joke is a lot more difficult (with the post title and ‘wait what’ reaction) than it actually is.
I can’t verify anything but it seems to me if you want to know everything you could possibly know about the disaster, "That Chernobyl guy" is the place to go.
Fun fact you can count to 27 if you cut your hand and count the bones.
I can and do count to 10 on one hand. I just use ASL numbers
I can count to twelve on one hand like the Babylonians

I can count up to 31 on one hand
Shit on it!
If I understand it correctly - that show was funded by Westinghouse. Who is a nuclear contractor and who’s biggest competitor is Russian nuclear companies. So I would take that show with a bag of salt
Man, so many memes are just a laugh track added after a joke lol
