The photo Bullet Through Apple by Harold Edgerton captures the
exact moment when a bullet pierces the fruit. To do so, his camera
shutter had to be faster than the speeding bullet. For very small scale
movies, far faster cameras are needed: ones that capture the action
using X-rays.

This article was amazing! One thing that I found really interesting was the wavelength of x-rays are shorter than an atom. Also, I know that x-rays are really dangerous, so what do the people that are working on this project have to wear all the time--led? Or is there some other way to protect the people from the x-rays? Another interesting thing I found was that each flash lasts less than one quadrillionth of a second, which is extremely fast. However, I have a question about this fact. Last year in science, we had a unit about atoms where we learned that atoms move slower in cooler temperatures and speed up when it is warmer. Is the speed needed to capture the atom picture needed for when the atoms are in warm temperatures or cooler temperatures?
I found this specific article unique. The section (not to mention image; wow!) about the 2 mile laser located at Stanford surprised me. It's truly astonishing how they can capture pure images of atoms through such a process of all of the different instruments used. On the topic of crystallography, I wish they could have expanded on it than it just being a simple term used in the description of an image. Relevant or irrelevant to the article, I quite wish that elaborated more on how the atoms moving within irregularly strong solids could be captured by issued x-ray beams.
I thought that this article was pretty cool. The fact that they can take a picture of a bullet going straight through an apple is awesome, and it goes to show how advanced technology is becomming. I wish that they could have explained the topic of crystallography better, but otherwise it was really awesome.
