Now, this is a difficult question to categorize (I'm new here, if I should move this somewhere else, send me a message) and I think I know the answer to it but I wanted to see what anyone else thought. Suppose you are without a computer or any type of hardware. Is it possible to use a formula to create random (or pseudorandom) numbers? At first, it seems impossible. Formulas are quite possible the most linear thing ever created and randomness is exactly the opposite - quite nonlinear. Whenever you run numbers through a formula, the numbers will always stay the same - nothing random about it at all. However, I'm not sure. Is it possible to create a working formula that uses a seed - a defined series of numbers? You could then feed that into some type of equation for getting random numbers - some computers do it in that method, but they have hardware which is capable of processing millions of calculations, and providing randomness. It's probably a silly question but I just wanted some input on what other people thought.
