I was watching Star Trek today and found it amazing that many of our modern gadgets mimic what we saw over the course of several Star Trek series.
Star Trek, original series: Flip-open communicator
Modern times: Clam shell cell phones
Star Trek, all series: Transporter
Modern times: Physicists have found a way to create a copy of an atom over a distance using a laser
Star Trek, TNG/DS9/Voyager: PADD
Modern times: iPad mini
Now we just need someone to come up with warp drive so we can study space that is further out.
