Sorry I'm just cleaning parts of my brain off my keyboard because MY MIND JUST GOT BLOWN'!

Reminds me of the first few minutes of Rosencrantz and Guildenstern are Dead. ;)

well assuming that there is something like true randomness of a coin

in real world, the difference between a mathematical model

and reality might seem small but for a human but it may be crucial for life

so if you show me a coin that shows 50 times heads in a row of 100

i will get suspicious.

i suggest some readings of nassim taleb

thanks for your answer, but here is something extra, how is this true in relationship with time? I mean if you count sequences from time zero to time finish this property can apply , because you can count all possible combinations, but what about if you only count sequences in one hour? or two hours, and the light switches are spaced 5 minutes apart. I am working on such a problem and I'm searching for a solution. Thanks

Okay. Back to the video instead of praising khan academy, I'm sure it just wants to know how people feel of the video. Phrases such as "omg this video portrays things soooooo much cooler!" are so cliche. Get to the point.

I completely agree with this video. I don't think truly random numbers are possible.

@viorel22cr Yes this property is taken into account when measuring the 'quality' of pseudorandomness (machine generated).

[viorel22cr]

can this be applied to computer generated random numbers?

@kbponline It's because videos and graphics convey much more information than the text do, and you use both ur eyes and ears to process these information.That's why videos seem more "meaningful" thatn text.

Its like having people spread randomly across a room. It cannot be done.
