Can We Achieve True Randomness?

Researchers typically use random numbers supplied by a computer, but these are generated by mathematical formulas – and so by definition cannot be truly random. ... True randomness can be generated by exploiting the inherent uncertainty of the subatomic world.

How do you get true randomness?

To generate “true” random numbers, random number generators gather “entropy,” or seemingly random data from the physical world around them. For random numbers that don't really need to be random, they may just use an algorithm and a seed value.

Can you prove randomness?

No, there is no such prove - if you have perfectly random numbers, the probability of each sequence of length n is equal. However, there are statistical tests to asses the quality of a random number generator, which is probably what you are looking for. See Diehard tests.
