Wichmann–Hill

Wichmann-Hill is a way of getting random numbers that computers can use. Sometimes computers need to randomly pick a number, like when you play a game or take a test online. Wichmann-Hill helps computers make different random numbers every time, so the game or test is always a little bit different. Wichmann-Hill uses math to make sure that the numbers are as random as possible, which means they don't follow any patterns. It's like picking marbles out of a jar, but the jar is really big and you don't know where the marbles are. Wichmann-Hill helps computers pick the marbles without knowing where they are ahead of time.
