Comptometers, Telephots and Stasis

Comptometers were a special brand of calculator; they were common at the end of the 19th century, and the early 20th. But when Cummings writes about the Grantline Comptometer, he's referring to something that we couldn't actually do until Mathematica came out.

And how about telephots? Videophones to you; this quote from early Gernsback is a good one. Also, here's a short article on stasis from an early Heinlein novel; think hibernation as opposed to freezing.
