nanoscale

In Education for the Nanoscale, students need to learn to work on the nanometer scale. This opens completely new dimensions on how we will approach and solve many problems of the future as we enter the Nanometer Age.”

-Heinrich Rohreer, Nobel Laureatehttp://news.nationalgeographic.com/news/2002/08/0822_020822_nanoscience.html

In 1959…

“Up to now we have been content to dig in the ground to find minerals, …ultimately in the great future we can arrange the atoms the way we want.”

-Richard P. Feynman, the man who dared to think small, 1959

The Future is Now!

Now we have new imaging and manipulation tools available to help us gather data about nanosized materials.

How Big is Nano?The Basics:•There are one million micrometers in a meter.•There are 1000 nanometers in 1 micrometer.

These prefixes can be confusing!

On the next few slides we’ll investigate what they mean.
