But its manufacturers like to point out its less-lethal capabilities. Instead of mowing people down, it can stick to the fine print of the first law of robotics and fire tear gas canisters, smoke grenades, smoke bombs and perhaps even Taser’s upcoming 40mm people-zapper projectile. Three were deployed to Iraq last year.
Finally, here is an absolute mind-boggler...a 1,500-year old computer:
In 1900, some divers found the wreck of a Roman vessel off the Greek island of Antikythera. Among the other treasures remanded to the Greek government was an unassuming corroded lump. Some time later, the lump fell apart, revealing a damaged machine of unknown purpose, with some large gears and many smaller cogs, plus a few engraved words in Greek. Early studies suggested it was some type of astronomical time-keeping device – researcher Derek J. de Solla Price laid the groundwork by establishing initial tooth counts and suggesting that the device followed the Metonic cycle, a 235-month pattern commonly used to predict eclipses in the ancient world.
The full function and beauty of the Antikythera device remained hidden until recent studies subjected it to more advanced imaging techniques. ...
The findings, published in Nature, are probably best described as "mind blowing." Devices with this level of complexity were not seen again for almost 1,500 years, and the Antikythera mechanism's compactness actually bests the later designs. Probably built around 150 B.C., the Antikythera mechanism can perform a number of functions just by turning a crank on the side.
Using nothing but an ingenious system of gears, the mechanism could be used to predict the month, day and hour of an eclipse, and even accounted for leap years. It could also predict the positions of the sun and moon against the zodiac, and has a gear train that turns a black and white stone to show the moon's phase on a given date. It is possible that it could also show the astronomical positions of the planets known to the ancients: Mercury, Venus, Mars, Jupiter and Saturn.
Sweet! Have a great weekend.
