What on Earth is spin? And why is it so special? In this TEDEducation video, educator Brian Jones explains how this dynamic affects our lives in all sorts of ways.

From 0 to 75mph in just three seconds — in just three strides, it’s faster than most of the world’s fastest super cars — the Smithsonian Channel describes the biomechanics behind why the cheetah is the world’s fastest land animal.
Follow this video up with this singular slow motion video of a cheetah running.

Earth Unplugged films the northern goshawk’s magnificent speed and precision skills in slow motion as it aims for lures and water balloons.

After this, watch an owl in slow motion, or up the challenge: How small of a space can a northern goshawk fly through?
According to the research, “a wet animal could spend 20% or more of it’s daily food energy to evaporate water in its fur, if it cannot shake.” Therefore, it’s super important to get dry! Earth Unplugged’s Sam and Simon slow down this phenomenon of mammals shaking to get dry — super slow-mo style — in this sixth episode by BBC Earth Productions.

Swiss photographer Fabian Oefner works with the intersection of art and science. He takes perfectly-timed photos of brightly-colored paint being spun at high speeds. From the artist:
“Black Hole” is a series of images, which shows paint modeled by the centripetal force. The setup is very simple: Various shades of acrylic paint are dripped onto a metallic rod, which is connected to a drill. When switched on, the paint starts to move away from the rod, creating these amazing looking structures.
The motion of the paint happens in a blink of an eye, the images you see are taken only millisecond after the drill was turned on. To capture the moment, where the paint forms that distinctive shape, I connected a sensor to the drill, which sends an impulse to the flashes. These specialized units are capable of creating flashes as short as a 1/40000 of a second, freezing the motion of the paint.
We’d love to watch high speed, slow-mo video of this project. See more of Fabian’s images here, and then check out his painting in magnetic ferrofluid project.
