text: star trek: is scotty's theory (movie #4) on "transparent aluminum" actually viable? has such really been made?   perhaps some molecular form involving aluminum could be transparent, but it hasn't been made yet.  that is one of my favorite scenes in that movie though.  i like when he tries to talk to the computer to get it to do what he wants.  scotty seems incredibly good with the keyboard considering he never has to use one in his time period.
