In a common scene on Star Trek: The Next Generation, captain Jean-Luc Picard would walk up to an impressive, high-tech-looking console set in the wall and sternly say to it: “Tea. Earl Grey. Hot.”
The console would shimmer and sparkle and, after a few seconds, a piping hot serving of tea complete with cup and saucer would materialize, ready for drinking.
The technology was known as a “replicator” because it replicated real things out of thin air. But, as it eventually turns out with much of Star Trek ’s gadgetry, the technology is not so fantastical after all.
