At this past weekend's North American International Toy Fair in New York, not every participant was a toymaker. In the back of the huge space was a booth for BuddyTag—a smart wristband that helps parents monitor children within 120 feet. BuddyTag was invented by Willie Wu after he lost his daughter at Six Flags. “His child did everything right—waiting in one place with an employee of the park," said Wu's sister, who was stationed at the booth. The kid was found in an hour, “but it was the worst hour of his life." It also sparked an idea.

Cavemen must have been perpetually late, given that humans didn’t get around to inventing the sundial until 1500 BCE. The first attempts at measuring time via sun movement were shadow clocks created by the Egyptians and Babylonians. These led to the sundial, an instrument that tells time by measuring shadows cast by the sun on a dial plate. Sundials were our preferred method of timekeeping until the mechanical clock was invented in 14th-century Europe.

A new camera developed at MIT can photograph a trillion frames per second. Compare that with a traditional movie camera which takes a mere 24. This new advancement in photographic technology has given scientists the ability to photograph the movement of the fastest thing in the Universe, light. In the video below, you’ll see experimental footage of light photons traveling 600-million-miles-per-hour through water. The actual event occurred in a nano second, but the camera has the ability to slow it down to twenty seconds. For some perspective, according to New York Times writer, John Markoff, “If a bullet were tracked in the same fashion moving through the same fluid, the resulting movie would last three years.”
