If you keep proving stuff that others have done, getting confidence, increasing the complexities of your solutions - for the fun of it - then one day you'll turn around and discover that nobody actually did that one! And that's the way to become a computer scientist.

Scientific knowledge is a body of statements of varying degrees of certainty -- some most unsure, some nearly sure, none absolutely certain.

Scientific knowledge is an enabling power to do either good or bad — but it does not carry instructions on how to use it.

We never are definitely right, we can only be sure we are wrong.

Words can be meaningless. If they are used in such a way that no sharp conclusions can be drawn.
