Binary is very good for counting with your fingers. With both hands you can count to 1023. One hand is 31, which is still usually more than you typically need to count. It's also trivial to do once you know how binary works. It takes very little thought, though potentially the decoding could take a bit depending on your proficiency.
Billions of years ago, our collective great-great-great-[several million more]-grandparent evolved a fin with a five bone structure. That idiot didn't know anything about common denominators, and now we're stuck with this numeric system that can't divide things into thirds without causing issues.
This would be great. I was researching why we don't have 10 based clocks and then I saw a video about why a 12 and 60 based system is actually much more convenient and now I would love a 'dozen based metric system'
Common denominators. You can divide base 12 into half, thirds, fourths, and sixths and still use integers. I find thirds to be particularly useful, so base 16 is out. Base 60 can do it, but that's getting unweildly.
Huh, that's a good point. A better universal naming system would be something like "Base x+1", with x being one integer lower than 10. So humans would use Base 9+1, and the alien would use Base 3+1.
*This has been on my mind all day and the more I think about it, the more obvious it becomes how fundamentally terrible the name "Base-10" is. How did this never occur to the people who coined the term? Even the system I suggested is flawed as it's still trying to incorporate the same bad logic.
A better system would be something like Base 9, stopping shy of the respective 10 in each system, or if it needs to be clarified, Base 9+0, as 0 is the extra digit in the first place, not 10.
we'd only be able to represent bases for numbers with one digit though because what does base 15+1 mean? the 15 could be in any base higher than 5. the clearest way would probably be to just represent it with lines or something "base ||||||||||"
It's only 15 to us because we use base 10 (or 9+1). Like how we have 4 through 9, but that aliens in the picture only count up to 3.
In the case of a mismatch, the culture using the higher base would just translate down (Base 21+1 in the given scenario).
Single units would probably be the simplest method, but also wildly impractical as the base gets higher. You really want to count each digit just to figure out someone uses Base 100?
I think that would confuse things more than it would help. It's base 5, unless it's base 10, unless it's base 50, etc. And then there's the rules designating numbers 1 below certain other numbers, or 2 below, depending on the system being used. That's a whole web of complications when communication is already murky.
One glyph to one integer communicates the number system being used more clearly.
let there be any base "b"
That can represent a number by the sum of their positional digits:
number = sum(d_i * b ^ i)
where i is the position index and d_i is the digit at this position. (note: index starts with 0, from the least digit farthest to the right)
I just realized that we call binary base2 and there's no 2 in that numbering system. We call hexadecimal base16 but there's no 16 (at least not like we know it). But then why is base10 base10? We have a 10...but it's not a single digit number.
"ten" is a fixed amount in base 10. A base 4 user may have an entirely different naming system for numbers above 3, so "ten" (which is written as 22 in base 4) could be twenty two, twoty two, dbgluqboq, or Janet. But similarly to how we don't have a single syllable, dedicated number name for decimal 22 (as in, it's composed of the number names 'twenty' and 'two'), they may not have a single syllable, dedicated number name for decimal 10 (which is '22' in base 4).
No, ten is a fixed amount in English. It has roots in base ten, but we also have eleven and twelve from other bases. (also dozen, gross, score.) In English there is no ambiguity when it comes to what number the word ten represents.
even when written out non base ten systems, are still possible to be non base ten.
It's only base ten when you convert from one base system to another. We are merely referencing between two base systems when we say that 4 bits is "16" because there are 16 possible options there. 16 is just our conceptualized version and conversion of that base system, in ours. You can read binary as if it's just powers of 2, it's incredibly trivial.
octal and hex are the best example of this, because octal skips numbers while counting. Hex introduces letters. Neither of which fly even remotely sanely through base ten. Unless you're converting.
A base 4 number system has 4 numbers in it: 0, 1, 2, and 3.
After 3 the next numbers are 10, 11, 12, 13, 20, 21, etc.
A base 10 number system has 10 numbers in it, 0 through 9.
Hexadecimal is base 16: 0-9 followed by A-F
The alien using a "base 4" number system does not have a single digit for the number "4". They represent four of something with the number "10", so for them, their four digit number system is "base 10".
The most reliable way to communicate bases would probably be using unary.
Now if your alien is using unary, that might not work, but it should for all higher bases.
I'm not sure if I fully understand.
I was thinking, wouldn't it be easiest to describe the system you use by taking the last number in your first decimum and then saying you increment it with one?
E.g. for base ten this would be: base 9 + 1
For binary it would be: base 1 + 1
For hexadecimal it would be: base F + 1
Etc.
