Movimiento Browniano
Three different views of Brownian motion, with
32 steps, 256 steps, and 2048 steps denoted
by progressively lighter colors.
Jan Ingenhousz first observed irregular motion of
carbon dust in alcohol in 1765. Jittering motion
was discovered by botanist Robert Brown in 1827.
He was observing minute particles within the
vacuoles of pollen grains.

La microscopía electrónica
La comprensión del arreglo atómico en materiales
semiconductores ha permito alcanzar un control de
las propiedades de materiales, con una precisión
muy cercana al nivel atómico. El desarrollo
vertiginoso de la microscopía electrónica en los
anos 1970, ha permitido la observación directa de
la estructura atómica. La aplicación de la
ciencia de materiales a los semiconductores ha
generado la microelectrónica, la tecnología de
registro magnético, la optoelectrónica, y
finalmente el Internet.

Que es la Nanotecnología
  • Ahora todo lo que es menor que una micra.
  • Futuro Todo lo que es del tamaño de un
    nanómetro.
  • Eventualmente Todo lo que involucra control de
    la materia a nivel atómico.

Hay bastante campo al fondo
(There is plenty of room at the bottom)
This classic talk that Richard Feynman gave on
December 29th 1959 at the annual meeting of the
American Physical Society at Caltech was first
published in the February 1960 issue of Caltech's
Engineering and Science. ? Richard Feynmann 1962

Foresight Conferences on Molecular Nanotechnology
27
The term nanotechnology was coined by the Tokyo
Science University Professor Norio Taniguchi in
1974 to describe the precision manufacture of
materials with nanometer tolerances, and was
unknowingly appropriated by Drexler in his 1986
book Engines of Creation The Coming Era of
Nanotechnology to describe what later became
known as molecular nanotechnology (MNT). In that
book, he proposed the idea of a nanoscale
"assembler" which would be able to build a copy
of itself and of other items of arbitrary
complexity. http//e-drexler.com/p/idx04/00/0404d

Steve Jurvetson, Venture Capitalist
Steve Jurvetson is a Managing Director of Draper
Fisher Jurvetson, a leading venture capital firm
with affiliate offices around the world.  He was
the founding VC investor in Hotmail (MSFT),
Interwoven (IWOV), and Kana (KANA). He also led
the firm's investments in Tradex and Cyras,
acquired for 8 billion. Previously, Steve was an
RD Engineer at Hewlett-Packard, where seven of
his communications chip designs were fabricated.
His prior technical experience also includes
programming, materials science research (TEM
atomic imaging of GaAs), and computer design at
HP's PC Division, the Center for Materials
Research, and Mostek. http//www.dfj.com/team/Stev

National Nanotechnology Initiative
Visionary nanotechnology venture capitalist Steve
Jurvetson stood behind President Bush during
todays signing ceremony in the Oval Office of
the 21st Century Nanotech Research and
Development Act. The bill puts the President's
National Nanotechnology Initiative into law and
authorizes 3.7 billion over the next four years
for the creation of the National Nanotechnology
Coordination Office and the funding of federal
government nanotechnology programs.
