Graphene, a nanocarbon material just 0.3 nanometers thick and 200 times stronger than steel, is starting to revolutionize construction. Discovered in 2004, graphene’s unique hexagonal crystal ...

At this rate, even if you had a perfectly hexagonal snow crystal, and you made approximately 10^34 snow crystals over the history of planet Earth, you'd only need to reach a size of a few thousand ...
