Clarke's Law
From Tardis Wiki, the free Doctor Who reference
Actually, the third of three dictums, Clarke's Law states that:
Any sufficiently advanced technology is indistinguishable from magic.
To use but one example, the Sycorax thought of blood control as form of sorcery and the Doctor as a user of witchcraft. (DW: The Christmas Invasion)
Direct reference
The Doctor reminded Ace of Clarke's Law. (DW: Battlefield).
Indirect reference
The Captain said his now-wrecked craft had posessed technologies "indistinguishable from magic" (DW: The Pirate Planet).
