The document provides an introduction to nanotechnology, including: 1) Defining nanotechnology as understanding and manipulating matter at the atomic and molecular scale to create new materials and systems. 2) Describing the need for nanotechnology education and training as about 2 million workers will be needed worldwide in 10-15 years. 3) Explaining how instruments like electron microscopes and scanning probe microscopes enabled the field of nanoscience by enabling visualization and manipulation at the nanoscale.
