A few decades ago, we knew of only a few forms of carbon: diamond, graphite, and amorphous carbon. Today, thanks to rapid scientific advancements in the world of nanotechnology, we have discovered many other forms of carbon.
One of the most important developments is the carbon nanotube (CNT), which is related to graphite. The molecular structure of graphite resembles stacked, one-atom-thick sheets of chicken wire. In conventional graphite, the sheets of carbon are stacked on top of one another, allowing them to easily slide over each other. When these sheets are rolled into a cylinder and their edges joined, they form CNTs, which offer extraordinary mechanical, electrical, thermal, optical, and chemical properties.

The Boston Marathon is less than a month away. If you are training for the 26+ miles of winding, hilly roads through and around Boston, the odds are good that you are using some kind of wearable fitness device to track your run. You may find yourself constantly trying to top the stats of your last run, pushing harder and racing against previous times, perhaps even risking injury. How did we end up training against our fitness devices instead of training with them?
