are digits of pi

[xybersurfer]

@martincs14 everything is a digit of pi if you look far enough

[adriangonsalves]

Thanks for shareing!!

[aahhpe]

This video is great ...thank you very much

[menkaur]

terrible terrible sound

[SantaDomingo]

it gets better when Chaitin starts, that's about at 4 minutes into the video.

[loveanpeace4eva]

i luv how that's all you comment on lol

[heloizyjhenifer]

Okay, now which of those is more random :)

Don't remember if Chaitin mentions in his book that proving randomness isn't an easy problem ^^.

[trombone7]

You're right. It isn't easy but it can be done. For instance, if you forget to write down your daily mileage for work and just try to make up all the numbers, they can tell.

[heloizyjhenifer]

haha nice, try to lie from the very begining next time, it might work better =).

About my guess numbers, i can hint you that one of them has 1 and only 0's after that, in a certain base ;).

[trombone7]

I've never been caught. My management is far too lazy to actually mathematically check. I just remember reading that trying to look random compared to true random is somehow discernible. So your top row isn't completely random ?

[heloizyjhenifer]

Sometimes something really random might look not as "random" as we'd like. Also if one tries to generate a string of random numbers mentally, there will be a definite bias very soon. You can think of Random as not-compressible-given-some-co­mpression-algorithm. A compression algorithm shrinks a few strings and expands the huge remainder of them. The former are non random according to the algorithm.

[trombone7]

Cool. What do read? I've been reading "User Illusion" by Norretranders and flipping through "Decoding the Universe" by Seife

[MrWilburne]

T-T-T-T-Today Junior!!!

[DrLight9]

bless you , chaitin. i hated you at first and now i love you. always look for the string and always pull it. and always find more complexity and beauty. thank you.

[5micky2]

dreadful sound quality, a shame since the topic is so compelling

[5micky2]

actually, the sound quality gets better half way through

[siamco]

hehe... a psychological problem that a good psychiatrist could have cured me of!
