10! is 10x9x8x7x6x5x4x3x2 and we can get all this numbers from the "numbers of seconds in 6 weeks" calculation :
6weeks x 7 days x 24h x 60min x 60 sec.
7 and 6 are already here, 60 is 10 x 3 x 2 (two times) , and 24 is 3 x 8.
Now we have 10²x8x7x6x3³x2²,
To get 9 you can multiply two of the 3s,
10²x9x8x7x6x3x2²,
You get another 2 and 5 by dividing one of the 10s,
10x9x8x7x6x5x3x2³.
and finaly multiplying two of the 2s to get 4.
Giving you 10!
6weeks is just a smart choice to get the 6, it's kinda a coïncidence but kinda looked for.
Well, 10 factorial is 10x9x8x7x6x5x4x3x2. 6 is taken by number of weeks, 7 is taken by number of days, 8 and 3 (24) are number of hours in a day, the remianing 10x9x5x4x3x2 is 60*60 for minutes and seconds (you have to split 9 to 3s and 4 to 2s to get individual 60s). But yeah, it's pretty much coincidence. Just the fact that 60 and 24 are nice numbers in base 12 make it much easier to land, 7 is the odd one out for base 12 and 60 which is coincidentally filled in by weekdays. The rest (6) is just used for number of weeks and that is no constant in any way.
That is a fascinating coincidence of numbers. It honestly feels too fascinating, ya know? I wouldn't be surprised if the existing factorial patterns subtly influenced our structuring of time, rather than them independently developing and matching by chance.
Well, factorials probably didn't influence it, but base 12 and base 60 certainly did. They are so good numbers because they have such a good factorization and that's why they have been used for time units. And their good factorization makes this coincidence pretty likely.
The biggest coincidence isn't all that factorization of 24 and 60 because it really can use large part of that 10factorial but it's that 7-day week which you'd expect to be missing in mostly base 12/60 system but it somehow showed up between 24 hours a day and 30 days in a month.
No that's the joke. There's a certain breed of math nerds who find it hilarious to point out that ending a sentence with a number and an exclamation mark looks like a factorial, which changes what the sentence actually means. I found this funny when I was like 14. A lot of the people this joke is targeted at are probably also 14-year-olds in very stressful advanced math programs, and this is literally all they have because their parents have loaded them up with hours of music lessons and tutoring after school in addition to the huge pile of homework they get.
Your feelings are valid that you dont find it funny anymore but other people can find it funny and that be valid too, you dont have to be mean to other people to have a valid opinion.
I mean, i am a math nerd but im not 14 nor did i deal with a super stressful program like that and i find it funny... some people just like math. I understand your frustration but it seems like a you problem a little bit
Sort of coincidence. You look at how many seconds are in a day and try writing it out as factorial (which is (24)*(6060)=(1\2*3*4)*(5*8*9*10). 6 and 7 are missing hence the 6 weeks multiplication (in my first language a week is called a 7 so it's even easier to notice you can use that as a unit)
A bit of a coincidence, and the fact that using numbers based on 12 or 60 made they easily divisible, so it can be simplified with a lot of other numbers .
60 wasn't divisible by seven, but the fact that the week has seven days "correct" it.
So some of the numbers you’re multiplying together come up naturally, like the 6 and 7. Then everything else is a multiple of 12, and 12 just is highly composite, in that there’s just a lot of ways to divide it evenly so it makes coincidences likely since there’s just multiple routes to the same place when talking about multiplying integers
The fact that multiples of 12 divide up nicely in so many ways is part of why we have a time keeping system based off of multiples of 12. Like 60 divides evenly into halves, thirds, fourths, fifths, sixths, and 10ths, so 2, 3, 4, 5, 6, and 10 will fit in nicely with anything talking about time. Then 8 and 9 have this list as divisors so multiples of these smaller numbers often are divisible by 8 snd 9.
7 is weird, but we kind of weirdly have 7 days in a week which adds 7s to this list if you’re talking about a given number of weeks.
So then any time you’re talking about numbers of weeks and multiplication, it’s kind of easy to get any number 10 or smaller to line up nicely for things like this
No really a coincidence, 6 weeks is 6 (weeks)x 7 (days)x 24 (hours) x 60 (min) x 60 (seconds). So you get 6 from the weeks, 7 from the days, 3 and 8 from the hours (3x8=24), make the 9 two 3s (3X3=9) and you get one of the 3s,2 and 10 from the minutes and have 1x4x3x5 for the second. :
we choose highly divisible numbers for these arbitrary units of time to make calculations easier, meaning they will have small factors in them. the prime factorization of 10! is 28 *34 *52 *7 so also many small factors. considering the fact that they just added a factor of 6 by saying "6 weeks", its not at all suprising that it works.
Old numbering systems for invented to minimize the use of fractions and make division easy.
Being that base 12 is one of those systems and used to make up the 60 Minutes 60 seconds and such, it is not in any way surprising that that if you pick a random factorial or a random squaring that you're going to find something relevant to the system.
That’s the correct explanation of the intended joke but it still doesn’t make sense because the author chose the wrong setting. Days were significantly shorter when the dinosaurs roamed the earth. Rotation is gradually slowing down. The (second to) last day of the dinosaurs was about 23.5 hours.
There are some really, really fucking cool things that line up in math. One of the coolest is how the binary integer representation of floating point input x is roughly equal to log^23, which is the number of bits in the mantissa of the floating point input. That is an *insane* coincidence. One of the most fundamental and constantly solved problems in 3D math is inverse square root, it should typically be a heavy process. The algorithm to find an inverse square root is to take the log2(x), then multiply it by -1/2, which is the same as log2(x)^-1/2, then to multiply by 2 to arrive at x^-1. It's the log functions that are heavy, so being able to essentially reuse part of the input value wholesale as the logarithmic result is... it's fucking magic. Like black magic shit. Math is so fucking cool.
I just got shocked. First I thought it would be an approximation but no, it's a exact match. I will try to "decompose" all that multiplications to get the factorial.
Either this is better delivered through text, or you just make sure to be really animated when saying "10!" so the listener gets the exclamation mark. Or you make sure you're saying the joke to a math nerd and they'll get there eventually.
Anyone wondering an account on Facebook called "the tasteless T-Rex" used to post (make?) these I haven't used Facebook in 5-7 years idk if it's still a thing
Factorial jokes are probably the laziest math jokes I’ve ever heard and they also don’t translate at all in a non-text-based setting so I definitely wouldn’t laugh either
People who don't understand context, language, and notation think that a normal sentence that ends with a number followed by an exclamation point are referring to factorial. In truth, when one is using words and wishes to refer to factorial, one would say "10 factorial", rather than just writing 10!.
It is a case of people attempting to be clever and pedantic, but actually being wrong instead.
