I like how people think DB failed.
The ball landed on the next number which showed that his 'calculations' were very close.
Do you honestly believe that he genuinely calculated (in his head), where the ball was going to land?
Even if he had hooked the roulette wheel upto a computer, he wouldnt get as close as he did on Friday. Bear in mind that on Friday, he was virtually correct. For all intent and purposes, he guessed the right number.
DB's theory of calculating the speed of the ball by the number of times it passes the green slot, sounds fine. However, the theory comes apart though on 2 fronts:
1. the human mind is not fast enough to be able to make such a complex calculation, under pressure, so quickly. But lets assume, for the sake of argument, DB's mind is beyond any other human mind that has ever existd...
2. when you observe a roulette wheel spin, you will often find that the ball does not land cleanly on a single slot. It often "bobbles" (ie. it jumps up and down to and from different slots, as it hits the ridges of different slots). Sometimes it does this. Sometimes it doesnt. And it is this "bobble" that simply cannot be calculated by a computer (at present) or human. This is where the massive randomness of it all comes into it.
Some people need to stop believing in the impossible and get real. I believe it is people who believe in the impossible, who are also most likely to taken in by those hypnosis stage shows.
I generally like DB's shows, but people have to understand that they are merely entertainment shows. Nothing more. Nothing less.
