Three so-called 'laws' written by the Atomic and Information Age fabulist Arthur C. Clarke.
When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
Any sufficiently advanced technology is indistinguishable from magic.
Clareke's 'laws' are remembered chiefly as the inspiration for the name for godtech artifacts which operate on principles which cannot be understood; such artifacts are generally known as clarketech.
