This mind-bending machine completes one turn every 2.3 trillion years

This machine by Arthur Ganson just blew my mind: its engine runs at 200 revolutions per minute but the last gear of its 12-gear mechanism is locked to a block of concrete. It looks still but, in reality, it is moving. You just can't see it because it completes one revolution every two trillion years. How the hell is… » 11/03/13 12:07am 11/03/13 12:07am

When you think of the fastest accelerators in the animal kingdom, large, muscular mammals will probably be the first that come to mind. But steady among them is the inconspicuous adolescent issus, who can hit an acceleration of 400 gs in 2 milliseconds flat (humans lose consciousness over 5 gs)—all thanks to what… » 9/12/13 4:20pm 9/12/13 4:20pm

Gear Clock Tells Time, Lies About Everything Else

You'd think that this $78 Jumbo Gear Clock sleeps alright knowing that, unlike its digital counterparts, it features 50 exposed moving gears that show off the otherwise hidden complexity of clockwork. But the Jumbo Gear Clock does not sleep well at all. The Jumbo Gear Clock lays awake at night because the Jumbo Gear… » 10/27/08 11:00am 10/27/08 11:00am

Bicycle With Unlimited Gears Inspired By Leonardo
