INTRODUCTION
Ever since the wheel was invented more than 5,000 years ago,
people have been inventing new ways to travel faster from one point to
another. The chariot, bicycle, automobile, airplane and rocket have all
been invented to decrease the amount of time we spend getting to our
desired destinations. Yet each of these forms of transportation share the
same flaw: They require us to cross a physical distance, which can take
anywhere from minutes to many hours depending on the starting and
ending points. There are scientists working right now on such a method
of travel, combining properties of telecommunications and transportation
to achieve a system called teleportation.
WHAT IS TELEPORTATION TECHNOLOGY?
The Teleportec communications system is unique and has been
designed to enable a life-size image of a person to appear within a 3D
environment. You can make eye contact with individuals, use props and
hold true two-way conversations - communicating naturally with anyone
or any group of people anywhere in the world, as you would if you were
there. After all 80% of communication is non-verbal. The only thing you
can't do is shake hand.
More advanced than video conferencing
Video conferencing has never presented itself as a realistic
alternative to face-to-face meetings because of its severe limitations -
only one person can speak at any one time creating an amplified feeling
of distance between participants. Teleportation allows a more natural
form of conversation due to the lack of latency - people achieve a sense
of presence that cannot be gained from any other technology
ELECTRONS TRAVELING ONE BY ONE
Current in conventional electronic devices is considered a kind of
flowing river of electrons, in which the electrons are as uncountable as
molecules of water. Reduce the dimensions of the material, and the
energy of those electrons becomes quantized, or divided into discrete
increments. Still, the precise number of electrons defies calculation.
Now, at the National Institute of Standards and Technology
(NIST) in Boulder, Colo., researcher Mark Keller is building a system to
make ultra-accurate measurements of capacitance, a form of electrical
impedance, by precisely counting the number of electrons put on a
capacitor. The heart of Keller's creation is a circuit that can count some
100 million electrons, give or take just one. This tally, along with a
commensurate measurement of the voltage on the capacitor, will be used
to determine capacitance with extreme accuracy. Thus, the capacitor will
become a standard, useful to technological organizations for such
applications as calibrating sensitive measuring equipment.
