The debate on Random Numbers
Can you all post your comments on random numbers?
To start the ball rolling...
This was from a friend by the name of Mak:
I think, too, that any number generated from a system is quite impossible to be a totally random one. I also think, rather radically though, that nothing is totally random
This is from somewhere:
This is from Alvin:The idea behind random numbers is not to be completely random, but to mimic randomness.
Imagine if you were a scientist working on a program to measure the effects of an earthquake on a building.
Since earthquakes can be considered somewhat random, you might want to see what happens if you do use
random numbers in terms of the earthquake.
Then you see the results. Then you tweak a variable here and there (proximity of building to other buildings, weight of building, etc)
and run it again. You would prefer in cases like this
to have the same earthquake, so the "random" numbers are run through again.
Anyway, to side-track a little, and though this may seem obvious to some, the concept of two calculations having the same results (in this case, F-f-f-f-f-f-f.... = F+f-f+f-f.... On both sides of the ball) emphasizes on the (erm...) fact that there are multiple ways of deriving the same result, further disproving the whole idea of
