The Curta is a small, hand-cranked mechanical calculator introduced by Curt Herzstark in 1948. It can be used to perform addition, subtraction, multiplication, division, and (with more difficulty) square roots and other operations.

The Curta's design is a descendant of Gottfried Leibniz's Stepped Reckoner and Thomas's Arithmometer, accumulating values on cogs, which are added or complemented by a stepped drum mechanism. It has an extremely compact design: a small cylinder that fits in the palm of the hand.

Curtas were considered the best portable calculators available until they were displaced by electronic calculators in the 1970s

and they cost £1000s brand new

waow.. i was just trying to buy a slide ruler, but this is entirely different.

(fyi aristo ruler's are 300 years old another mechanical computation devices.

they are much cheaper so they survived till the electronic calculaters get cheeper. they could make trigonometrical and logarithmical calculations by that time but no precise calculations just one or two digit.. like 6,8x 10^3... by that times only univercities had computers and students had to queue long long lines while doing homeworks....)

i soo want one in case of a global blackout or zombi infestation.. who would do these redicoulous computations then. i would be soo bored, dont even wanna think about it.

modern calculators are definitely easier and much more efficient, but this strangely looks a lot more fun!

There is already a mechanical calculator, still in use (last time I checked) in one of the world's most advanced countries. It's been around for thousands of years and in the hands of a skilled operator can deliver results of ordinary arithmetic as fast as a digital calculator. Ladies and gentlemen, the abacus.

How many years of thinking and try it will have lasted!
