A Treasure Trove for Science
Surely you have seen dragonflies hover. But did you know that they were also capable of flying backwards? Or even up-side down like a vintage double-decker during a daring air show? And that they could activate each one of their four wings separately – working at varying speed and propelling in different directions, all at the same time? Today it is possible to shoot images that are thousands of times faster than our own vision. Or slower. We can see how nature’s devices work – and imitate them. Helicopters or mechanical drones pretty much simulate the congenial dragonfly’s techniques. We live in a world of invisible beauty, too subtle to be perceptible to the human eye. Louie Schwartzberg shows breathtaking images during his fascinating TED talk.
