So what's nanotechnology?

Q. I'm a junior in high school and my science teacher is encouraging me to think about a career in the new field of nanotech. I'm not sure it's going to be around when I'm ready, or if it's going to be a great career and I don't want to let just one person influence me. What do you find?

Ans. Other readers may want to know, as you obviously do, that Nanotechnolgy, shortened to "nanotech," is the study of the control of matter on an atomic and molecular scale. There has been much debate on the future implications of  Nanotechnology because it has the potential to create many new materials and devices that may have the potential to adversely affect the environment. But despite "doomsday" scenarios, The National Science Foundation estimates that the world will require 2 million trained nanotechnologists by 2015.  Currently, there are only 20,000 nanotechnologists worldwide, making the need for career training immediate.
