How Does True Random Numbers - Computerphile Work?

True random numbers are like flipping a coin, but instead of just heads or tails, you get all sorts of wild results that no one can predict.

Imagine you're playing with a friend in the park. You both have a bag full of different colored marbles. Each time you want to pick a number, you shake the bag really hard and grab a marble without looking. The color you get is like a random number, it could be red, blue, green, or even purple! And because you shook the bag so much, no one can tell which color will come out next.

True random numbers work in a similar way, but instead of marbles and bags, they use things like electricity and heat. A special device called a random number generator uses tiny changes in these things to pick numbers, and those changes are so unpredictable, even the computer can't guess what will happen next.

Sometimes people use coins or dice to make random choices too. But true randomness is like having an invisible friend who decides the outcome without anyone knowing how!
