6. Origins of Nanotechnology
 Richard Feynman first conceived the idea of
molecular manufacturing in 1959
 Richard Feynman was the first scientist to
suggest that devices and materials could
someday be fabricated to atomic
specifications
 In 1986, K. Eric Drexler introduced the term
nanotechnology from there Scientific
research expanded to what we know today.

7. Why Nanotechnology?
 At the nanoscale, the physical, chemical,
and biological properties of materials differ
in fundamental and valuable ways from
the properties of individual atoms and
molecules or bulk matter.
 Nanotechnology research and
development is directed towards
understanding and creating improved
materials, devices, and systems.
