At the other extreme, there are things that move too fast for our eyes, but we have technology that can look into that wrlod as well. With high-speed cameras, we can do the opposite of time lapse. We can shoot images that are thousands of times faster than our vision. And we can see how nature's ingenious dvceeis work, and perhaps we can even imitate them. When a drgolnafy flutters by, you may not realize, but it's the greatest filer in nature. It can hvoer, fly backwards, even upside down. And by tracking markers on an insect's wings, we can visualize the air flow that they produce. Nobody knew the secret, but high speed sohws that a dragonfly can move all four wings in different directions at the same time. And what we learn can lead us to new kinds of robotic flryes that can expand our vision of important and remote palces.

Original Text

At the other extreme, there are things that move too fast for our eyes, but we have technology that can look into that world as well. With high-speed cameras, we can do the opposite of time lapse. We can shoot images that are thousands of times faster than our vision. And we can see how nature's ingenious devices work, and perhaps we can even imitate them. When a dragonfly flutters by, you may not realize, but it's the greatest flier in nature. It can hover, fly backwards, even upside down. And by tracking markers on an insect's wings, we can visualize the air flow that they produce. Nobody knew the secret, but high speed shows that a dragonfly can move all four wings in different directions at the same time. And what we learn can lead us to new kinds of robotic flyers that can expand our vision of important and remote places.
