# PSEUDO-RANDOMNESS IS THE OPPOSITE OF RANDOMNESS How to Randomness

When we say “pick a random number” the obvious problem is that randomization is not possible. So you’re stuck with pseudo randomization, and this is not all, there is another problem as well.

if I pick a random number and it’s between 0 and 100 your odds of figuring it out is 1/100. But if I pick a number from the range 0 to 1000 and I tell you the range, then the odds for you guessing it is  1/1000. How if I don’t tell you that it’s 0 to 1000. So actually it can be just one of 1000 integers, but you can’t know that. So it becomes as random as having to guess for numbers between 0 and infinite.

That’s the problem. How do you pick a number randomly from infinity?

To summarize. We have random which is void of any tampering. It is the entire number space as it is. Actually it’s wrong to even say “number space” because it implies limits. Indeed, it is infinity. Now let’s take a number out of that by some means, now we’re cutting down the entropy from maximum (pure random) to something that no longer is random. We’ve introduced order to where there was no order before. We’ve fundamentally altered the system by tampering with it. Now there is no randomness left.

There is still entropy, but that is not the same thing as “random”. Actually, entropy is a measure of order and not the measure of randomness. It’s the measure to say how far we’ve come from randomness.
