what is random?

The word random is used to express lack of order, purpose, cause, or predictability in non-scientific parlance. A random process is a repeating process whose outcomes follow no describable deterministic pattern, but follow a probability distribution.

is this website real random?

well, no... all the stuff you can see here is part of a database that i (and you) have filled. but you may have seen that the probability of landing on one or another stuff changes. i made it like this because you need to see the whole database before seeing something again.

can i choose what i see?

no, you can't.
