"It's just a Coincidence"

[@digitalgenius111]

IMPORTANT At 1:02 I said that, in the first 1000 digits of pi, there is a 100% chance that we would see the same digit 3 in a row. That is false. Assuming the sequence is random, there is always a chance that we woudn't see the same digit 3 times in a row. The actual probability is not that easy to calculate. It's approximately 99.99%. Calculating the probability of getting 6 digits in a row also isn't straightforward. I said that that it's 0.1%. It's approximately equal to 0.93%. Thanks for all the comments pointing this out and sorry for the mistake, hope you enjoyed the rest of the video.

[@theterron7857]

For some of them it's true, but all of the patterns of numbers repeating in irrational numbers are coincidences, because they exist only in a base 10 counting system, which is human made. Maths works regardless of how many digits we use to form our numbers, we could write pi only with 0s and 1s if we wanted to, and for any number of digits we use for a counting system, there will be different patterns, so yes. Those are actually all coincidences.

[@UltraLuigi2401]

@@theterron7857 While it's not entirely wrong to call them coincidences due to how obvious the patterns are in base 10, looking at the representations in other bases for long enough is bound to lead to the discovery of interesting patterns, simply due to the sheer number of possible patterns one could find. Since the fact that patterns can be found is essentially guaranteed, what the patterns are is irrelevant and calling them coincidences feels a bit disingenuous.

@@SBImNotWritingMyNameHere A bit of both. It started as being used to describe features of how things seem to work. If you have one apple, and another apple, then putting them together gives two apples. There are a lot of properties of math that are actually physical like that, which are then described using rules. But then those rules can also be used for other things, taking us into the realm of 'pure mathematics' which seems disconnected from the natural. But it is all still based in those rules that describe how natural things work. The thing is that occasionally the 'pure mathematics' is later discovered to actually apply to something real, after the math was developed. As an example imaginary numbers were found to be useful in mathematics hundreds of years before they showed up in electrical engineering and quantum mechanics. So it seems in some way that the natural world really does have math at its heart, and we are really just discovering it more than inventing it.

@@matitello4167 nah. I don't think there is such a thing as meeting percent change at some point, from which point things become more likely or surprising. A 1% event need not happen within the first 100 trials. It need not come every hundred trials. It does not even have to come within the first 1000 trials, or every 1000 trials. The idea that it must, is the gamblers fallacy: the idea that certain outcomes become 'statistically due' to happen if they haven't come in a while, as if the amount of trials, and their outcomes, have some kind of influence on the next one in order to force statistics to balance out. Trials are only independent if such influence does not exist. So while you expect a 1% event every 100 times, there might not be one for 100000 trials and then, suddenly, there could be 1010 in close succession, and the stats would still work.

4:15 The result is the original number mod 9 (assuming it's natural and a version of mod where 9 mod 9 is 9, but the usual numeral system is used). So, you can just 1*2 = 2 2*2 = 4 4*2 = 8 8*2 = 16 = 7 7*2 = 14 = 5 5*2 = 10 = 1 (all mod 9)

congrat you found what was behind this "coincidence". Now you can do that for everything he said in his video (except for the approximation, these are just scams)

[@orisphera]

​@@midahe5548I remember making a separate comment about another one For the first one, I had some thoughts then, but I finally figured it out now. The second digit is the arithmetic mean of the other two. So, it's 111111(the second digit) ± (100001 - 1100)(the difference). Both are divisible by 37 (111111 = 91*1221 = 3003*37, 98901 = 81*1221 = 2673*37. In fact, all these numbers are divisible by 1221

[@noname117spore]

Just to check the 6 weeks = 10! actually makes perfect sense. A week is 7 days and there’s 6 of them, so that handles the 6 and 7 in 10!. A day has 24 hours, which is 8*3, so that takes care of those factors. An hour has 60 minutes, which is 2*3*10, taking care of the 2 and 10. Since 9 is 3*3, we can split it into 2 factors of 3, and have this take care of one of them. A minute has 60 seconds, which is 3*4*5, taking care of the 4, the 5, and the other 3 leftover from the 9. And of course 1 times anything is itself. You could say it’s somewhat coincidental, but inevitably we’d math time with numbers divisible by 2s, 3s, and 10s, and that handles most of the factors of 10!, then getting lucky with 7 day weeks gets us the hardest to get factor, leaving just one last factor of 6 to add in. Going from 6 weeks to 4 weeks for 8! minutes also makes sense. You’re swapping which factors apply to seconds and minutes in the above scenario, and by removing seconds removing a factor 10, and one of the factors of 3 from the 9. You’d be losing a factor of 2 as well, but by changing it to 4 weeks from 6 you effectively gain it back for losing the other factor of 3 that makes up the 9, getting 8!.

5:10 look what I found for 4 digit numbers: 1420^3+5170^3+1000^3 = 142,051,701,000 2 digits have several solutions as well, like: 16^3+50^3+33^3 = 165033 22^3+18^3+59^3 = 221859 34^3+10^3+67^3 = 341067 44^3+46^3+64^3 = 444664 48^3+72^3+15^3 = 487215 98^3+28^3+27^3 = 982827 98^3+32^3+21^3 = 983221 After that I checked for two 3-digit numbers and 2nd powers, and found only this: 990^2+100^2 = 990100 But I guess these results are not that beautiful because of how we group digits in triples.

[@Prosaicus]

He said it was "around 6.02·10²³" because he omitted the last 6 decimal places. What makes this property of Avogadro's number such a big coincidence is how arbitrary its definition originally was. Avogadro's number was originally defined as the number of hydrogen atoms in one gram of hydrogen. A gram was originally defined as the mass of one cubic centimeter of water. And a centimeter was originally defined (during the French Revolution) as 10⁻⁹ times the distance from the North Pole to the Equator along the meridian passing through Paris.

1:35 You said that the probability that six digits in a row are equal in the first thousand digits of pi is .1%, but I beg to differ. As you have demonstrated in this first few minutes, the probability of that happening is 100%, because it actually happens. I think what you intend to say is that if we consider a number whose digits are generated randomly, then the probability of getting six equal values in a row is approximately 0.1%. While don’t think that the notion of random is coherent, I will concede that it may make sense in probability calculations that the event of having six equal digits in a row in the first 1000 digits of a number, under the equally likely assumption, maybe as you claimed .1%; this is certainly very different from the claim that a number whose expansion we know through the first 1000 digits has a .1% probability of a certain string of digits in that first 1000 digits.

[@TriglycerideBeware]

With continuous probability distributions, the probability of any individual event happening is infinitely small, so we say 0%, but still events happen anyway. So sometimes our intuition about what it means when something has 0% or 100% probability needs to be loosened, to not merely mean impossible/certain. ...that being said, selecting random digits is a discrete process... so I have no idea where the 100% came from either. Unless he's trying to say that pi *isn't* a random sequence, and it's always the same? But then so many of his other points are completely invalidated. Either way, there are quality issues.

[@geekjokes8458]

​@TriglycerideBeware it's not just continuous distributions, infintine number of things can sometimes be like that - we expect pi and some other trancendental numbers to be "normal", which means we think we should be able to find any finite string of digits somewhere in them with 100% probability i think there's a mistake in the video because he says "within the first 1000 digits" which is just not true...
