Title: The principles of physics, as far as I can see, do not speak against the possibility of maneuvering


1
There is plenty of room at the bottom
The principles of physics, as far as I can see,
do not speak against the possibility of
maneuvering things atom by atom it is
interesting that it would be, in principle
possible for a physicist to synthesize any
chemical substance that the chemist writes down.
Give the orders, and physicist synthesizes it.
How? Put the atoms where the chemist says, and
so you make the substance

Humans appear on Earth about 230 days ago and
live in caves until early May ! (I fear that
some people still live there now)

If you want to get more info about nanotechnology
or even get inspiration about possible
applications, check out this special issue of
Scientific American
Some of the applications outlined there may be
rather far fetched, but its okay one never
really knows

Before we start building these nanomachines or
even start thinking about doing so, we have to
learn about surfaces and surface patterns. Lets
start then

Promise of nanotechnology (M. Roco, Senior NSF
and government advisor)
  • Knowledge base better comprehension of nature,
    life
  • A new world of products 1 trillion / year in
    10-15 years
  • Materials beyond what chemistry can do
    340B/y in 10 years for materials and
    processingElectronics in 10-15 years 300B/y
    for semiconductor industry, times more for
    global integrated circuits Pharmaceuticals in
    10-15 years about half of production will depend
    on nanotechnology, affecting about 180 B/y
    Chemical plants in 10-15 years nanostructured
    catalysts in petroleum and chemical processing,
    about 100B/y Aerospace (about 70B/y in 10
    years, estimation by industry group)
  • Would require worldwide 2 million nanotech
    workers
  • Improved healthcare extend life-span, its
    quality, human physical capabilities ( 31B in
    tools for healthcare in 10 years)
  • Sustainability agriculture, water, energy
    (45B/y in 10 years), materials, environment
    ex lighting energy reduction 10 or 100B/y

of commercial applications of nanotechnology

Do ChEM-ies fit into the NANO-world?
Absolutely YES. Many new great opportunities
exist for growth, development, and progress in
traditional areas NANO!
Traditional Chemical Engineering morphed into
many new fields And it pays off! Graduates
with B.S in Chemical Engineering (universal
engineers) are the highest paid engineers in the
US (starting 56K annually)
Wheel of fortune!
