50 Greatest Breakthroughs Since the Wheel - The main rule for this exercise was that the innovations should have come after widespread use of the wheel began, perhaps 6,000 years ago. That ruled out fire, which our forebears began to employ several hundred thousand years earlier.
Seeing Through Camouflage - To experimentally assess which types of visual camouflage better
interfered with learning, Toschianko had human participants play a
simple computer game. A computer-generated photo was presented on a
touch screen, and the participant had to touch the spot on the photo
where they thought they saw a triangle that looked like a hidden “moth.”
The Incredible Shrinking Plane Seat - This doesn't sit well with many travelers, particularly those who are
large or overweight. Arm rests and aisles are also getting slimmed to
wedge in the extra seat, meaning more elbows get bumped. And while seats
are now being designed more ergonomically, with better cushions and
head rests, the improvements don't stop people from rubbing shoulders.
