Since I was a child, the crystal structure of salt (NaCl) has always been my
favorite. One of the reasons for this is because I find it fascinating how
orderly and straight the unit cell is. I find it interesting when looking at at
a ball-and-stick type model of NaCl because it reminds me of looking into an
infinity type mirror. I am also intrigued by sharpness of the corners and how
straight the edges can be. Even though the NaCl unit cell is simple, it is
amazing to me how something so simple can be so important for living organisms.
These are the reasons why I find the salt crystal beautiful.—Lindsey
