Randomness is an abstract, mathematical n...Correct. Randomness is an abstract, mathematical notion that does not directly exist. <br /><br />The idealization involved in the concept of randomness starts from the idea of an absence of *some* form of order, and then, in the limit, it goes to the idea of an absence of *every* form of order. <br /><br />Taken in this ``purest'' form, randomness is a purely mathematical concept; it is a concept of method alone. It cannot concretely exist for a similar set of reasons that objects of zero or infinite size cannot.<br /><br />Thus, first, it's best to begin with relative degrees of randomness. <br /><br />For instance, a complete polynomial of degree 7 is more complex than another with a degree 3. Hence, predicting the next number in a discrete data-series generated using a 7-degree polynomial, is more difficult; it takes more computational effort; the data series generated shows less order in the successive numbers. Hence, we can say that a 7-degree polynomial-generated series shows more randomness than a 3-degree one. <br /><br />From this viewpoint, generation of a purely random sequence would require an infinite-degree polynomial. <br /><br />Those who say that perfect randomness *physically* exists---whether at the level of stat. mech. or QM, or QFT---are welcome to keep themselves engaged with infinite-degree polynomials, and shut their mouth up in the meanwhile. <br /><br />(Guess the same argument can also be made using the Fourier transform, but polynomials are simpler, and I guess, equally powerful (if not more) for the purpose.)<br /><br />Best,<br />--Ajit<br />Ajit R.
