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 12:07am11/03/13 12:07am

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 4:20pm9/12/13 4:20pm

If Google Axes Six Unpopular Brands and Nobody Is Around to Use Them, Does Their Demise Make a Sound?

History is littered with the corpses of failed products—from Edsels and DeLoreans to Zunes and everything on CBS's early season lineup. Google is no different. It's just announced that it's culling six services most people didn't know existed...because nobody actually used them. »11/23/11 3:00am11/23/11 3:00am
