Clarke's Three Laws are three rules created by science fiction writer Arthur C. Clarke. They are:
1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right.
This means that when an experienced, smart scientist says that something is possible, it is usually true. We should believe them even if it is hard to understand.
2. When he states that something is impossible, he is very probably wrong.
This means that when an experienced, smart scientist says that something is impossible, they are usually wrong. It might still be possible.
3. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
This means that to see what is truly possible, we have to try things that might be impossible. We might learn something new.
