A truly logic system would be entirely designed around a base-12 number system. But we were born with an imperfect set of 10 fingers and that doomed us.
Those aliens have 6 fingers. It’s an absolutely ironic twist that their discussion on measuring systems is super illogical for them, and yet logical is the verbiage they use.
Care to elaborate on how base 12 would be better than base 10 in this case?
Basically it’s because 12 is more divisible than 10. Factors of 10 are 1,2,5 and 10. 12 has 1,2,3,4,6 and 12. This gives more flexibility when discussing numbers. Our time is technically using base 12, which is why we can say quarter past 4 and it means a traditional whole number. That’s the argument I’ve heard anyway
I believe this is also why we have 360 “degrees” in a circle, and not 365. The ancients hated that a year was clise to, but not exactly, 365 days. They chalked it up to the imperfection of Earth relative to the heavens. But a perfect year should be 360 days because it is divisible by every single digit number but 7.
7.62mm is more than 5.56mm but 'muricans (fuck yeah) still chose AR-15s because freedum. Where is your God now? /s
I’ve heard before it’s because 1/3 can be represented as a whole number.
Just like feet, which can have 12 inches. But if we want to get more precise we start cutting inches into eighths for some reason 😅
I always use decimal inches wherever possible, personally. Makes so much more sense to me than “3/64” or some crap like that
Base 6 however is perfect for 2 hands with 5 fingers each. You can easily represent the six possible digits 0 1 2 3 4 5 on each hand, and can therefore comfortably count to 55 (decimal 35) with two hands, using our familiar place-value numeral system.
Base 10 is the most easy to scale, you just move the coma and add 0s. Base 12 doesn’t allow that easily
A base 12 number system would have two extra symbols. Twelve would be written 10 and be called ten, and the number 144 would be written 100 and be called one hundred.
Everything you may think is inherent to base 10 is largely not. The quirky rules of 9’s multiplication table would apply to 11’s. Pi and e would still be irrational, and continue being no no matter which base of N you choose. Long division would work the same. Etc.
What if I choose base Pi? Then pi = 1
Checkmate.
Oh nvm, you did say base of N, but that’s boring.
Yep. In computer science you sometimes need to calculate with hexadecimal numbers where 10-15 are the letters A-F. You just use another factor for scaling “easily”.
In hexadecimal 10 is 16 in decimal. So if you do C * 10 it’s C0 but that is 192 in decimal (12 * 16, remember the base is 16).
Whats cool though is that (all hexadecimal):
10 / 2 = 8
10 is 2 to the power of 4 which means 10 is divisible by 2 4 times.
Similarly (and arguably even cooler) with a base 12 system 10 is divisible by 2 AND 3!
10 / 3 = 4
10 / 2 = 6
I’ll also defend fractional measurements over decimal to my dying breath. Decimal measurements can’t express precision very well at all. You can only increase or decrease precision by a power of 10.
If your measurement is precise to a quarter of a unit, how do you express that in decimal? “.25” is implying that your measurement is precise to 1/100th - misrepresenting precision by a factor of 25.
Meanwhile with fractions it’s easy. 1/4. Oh, your measurement of 1/4 meter is actually super duper precise? Great! Just don’t reduce the fraction.
928/3712 is the same number as 1/4 or .25, but now you know exactly how precise the measurement is. Whereas with a decimal measurement you either have to say it’s precise to 1/1000th (0.250), which is massively understating the precision, or 1/10000th (0.2500), which is massively overstating it.
Fractional measurements are awesome.
This is one of the dumbest fucking trolls I’ve ever seen.
Congratulations? I guess?
i’ve never heard of anyone using non-reduced fractions to measure precision. if you go into a machine shop and ask for a part to be milled to 16/64”, they will ask you what precision you need, they would never assume that means 16/64”±1/128”.
if you need custom precision in any case, you can always specify that by hand, fractional or decimal.
But you can’t specify it with decimal. That’s my point. How do you tell the machine operator it needs to be precise to the 64th in decimal? “0.015625” implies precision over 15,000x as precise as 1/64th. The difference between 1/10 and 1/100 is massive, and decimal has no way of expressing it with significant figures.
No measured value will be perfectly precise, so it doesn’t make sense to use that as a criteria for a system of measurement. You’re never going to be able to cut a board to exactly 1/3 of a foot, so it doesn’t matter that the metric value will be rounded a bit.
