"We'd have most of what we predicted of the conquest of space, if we hadn't ignored parasite control."

| Grantline Comptometer | ||
| Key-driven computer/calculator that easily solves even calculus problems. |
The Grantline Comptometer is a very early reference to computers or machines that can solve even the most complex problems simply by entering the necessary parameters of the problem.
| Above it was a shelf, with one of the Grantline comptometers, the mathematical sensation of some years back. It was almost a human mathematical brain.
Under its keys the most intricate problem of calculus was automatically resolved, as surely as an ancient adding machine did simple arithmatic. |

This device was an extension of the Felt Comptometer, a calculating machine that was first built in the 1890's and developed through the 1930's. Comptometer schools were opened, and equipped with the machines to train the necessary operators. Comptometers had full rows for sets of numbers; it didn't matter what order the digits were entered. Early versions performed addition and subtraction; later models performed multiplication and division, and even square roots.
The Grantline Comptometer presages systems like Mathematica, that actually do allow the user to type in a calculus formula; the software then solves the equation for you.

Technovelgy (that's tech-novel-gee!) is devoted to the creative science inventions and ideas of sf authors. Look for the Invention Category that interests you, the Glossary, the Invention Timeline, or see what's New.

'A worker replaced by a nubot... had to be compensated.'
'... forcing the energy transfer which allowed him to regrow his lost fingers.'
'The car surged and lifted, clearing its top by a negligible margin.'
Science fiction authors are serious about sleep, too.
'I had explained," said Nessus, "that our civilisation was dying in its own waste heat.'
'Just what did I want Flexible Frank to do? - any work a human being does around a house.'
SF writers have thought about this since the 19th century.
