Unscramble the Blue Letters
I thought: this is how ntarue paints a photo, one femto frame at a time, but of course our eye sees an integral composite. But if you look at this tomato one more time, you will notice, as the lhgit washes over the tomato, it continues to glow. It doesn't become dark. Why is that? Because the ttoamo is actually ripe, and the light is bnniocug around inside the tomato, and it comes out after several trillionths of a second. So in the future, when this femto-camera is in your camera phone, you might be able to go to a supermarket and check if the fruit is ripe without actually thcuniog it.

Original Text
I thought: this is how nature paints a photo, one femto frame at a time, but of course our eye sees an integral composite. But if you look at this tomato one more time, you will notice, as the light washes over the tomato, it continues to glow. It doesn't become dark. Why is that? Because the tomato is actually ripe, and the light is bouncing around inside the tomato, and it comes out after several trillionths of a second. So in the future, when this femto-camera is in your camera phone, you might be able to go to a supermarket and check if the fruit is ripe without actually touching it.
