# Interesting finding about PI and scientific constants

## Recommended Posts

Dear all,

I explored the value of PI up to 10 million digits with the following link

http://pi.karmona.com/

From here I realized that it included many scientific constants. Below are some examples (See the string in BOLD)

And maybe there are more cases. I wonder this interesting finding is only accidental, or there is any implicit rule here.

Any feedback or discussion can be sent to theodorenghiem@yahoo.co.nz

It’s nice if you can share my article in social media for more opinions

The probability of finding a few digit number in a string of 10mln digits is huge. It would be odd if the numbers you found would not be there - you'd actually have my attention then.

Yes, exactly.

10 million digits is enormous and there are bound to be coincidental correspondences with "significant" numbers. I am sure you could find your (or someone's close to you) birth date and year in there. This doesn't mean anything, it is a basic coincidence.

In infinitly long, random, not repeatable, sequence of digits, sooner or later you will find the all possible combinations of digits.

1.67*10^-27 kg is mass of proton only in kg as unit.

In electron volts, it's 938.272 MeV/c^2

So the same with the all other physical constants.

They can be converted to completely different units.

Phew, you're 3 years older than me

My birthday comes up 12 times in those 10mln digits from the link in the OP.

Although we don't actually know if that is true of Pi, as we don't know if it is normal or not.

In 10 million random digits, there are almost 10 million strings of six digits. There are only one million such strings, so any string is expected to show up about 10 times, as illustrated by koti.

On average, strings of seven digits occur only once, but for individual strings, that is not a certainty. As expected, about half the constants searched have six digits, and about half have more.

Originally, I also had the same thinking like yours by considering it as coincident. However I replaced PI with other irrational number, such as Euler number or golden ratio, and replicated all above testing. This time these values above could not be found with up to 5 or 6 digits like the result with PI.

So I declare that this is PI's secret that needs to be investigated more

The numeric string 010271 appears at the 1,135,207th decimal digit of E

The numeric string 3141593 appears at the 7,550,758th decimal digit of E

The numeric string 667408 appears at the 1,984,196th decimal digit of E.

The numeric string 167262 appears at the 5,185,365th decimal digit of E.

I call shenanigans - my birthday, Pi, G, and M_p all in first 10,000,000 digits of Euler's

for 8 digits you need more patience

The numeric string 01021971 appears at the 32,524,228th decimal digit of the Square Root of 2

The numeric string 31415927 appears at the 22,527,250 decimal digit of the Square Root of 2.

No point in doing G as we are only sure to one (ish) part in 10thousand

The numeric string 16726219 appears at the 36,596,663rd decimal digit of the Square Root of 2.
