Cary Huang (with a little help from his twin brother, Michael) built the interactive web page "The Scale of the Universe 2." It's their second pass at the concept, according to Discover Magazine.
With it, you can scroll down to see a representation of the microscopic (i.e. E. coli bacteria), and scroll back out to see the galactic.
ABCNews.com writes the ninth graders from Moraga, California were inspired by a teacher to create the page:
"My seventh grade science teacher showed us a size comparison video on cells, and I thought it was fascinating. I decided to make my own interactive version that included a much larger range of sizes," said Cary in an email forwarded by his mother. "It was not a school project -- just for fun. However, my science teacher loved it so much she showed [it] to the class! My brother, Michael, helped me put it on the internet." Cary said he worked on the project, on and off, for a year and a half, getting information from Wikipedia and astronomy books. It is now spreading virally online.
