In 1956-58 the transistor found one of the most spectacular
applications. It helped Russian and American specialists to launch the
first satellites and to open the space age. Only a few of the biggest
satellites have been able to carry vacuum-tube equipment. Most
satellites have appended on transistors not only for reporting back to
the earth but for operating the instruments with which the satellites
explored the mysterious regions around the earth.
But the most striking aspect of the transistor is not the host of
devices it made possible. More important was its effect on a new
branch of science and technology which may be called “solids-state
electronics”.
Pocket-size TV Camera
The ultra-miniature TV camera was made possible by a new
design approach, which combines transistors, specially developed
transistor circuitry and a new half-inch vidicon camera tube.
The pocket-size TV camera (JTV-1) weighs less than, pound
and measures only 1 7/8 ths by 2 3/8 ths by 4 1/2 inches. It can be
operated in the palm of the hand, used with an attachable pistol-grip
handle, bolted to wall or floor, or mounted on a tripod.
It is the first TV camera of its type to incorporate a
photoelectric control, which enables the camera to accommodate
changes in the order of 100 to 1 in scene lighting. Made rugged for
military airborne, mobile, and field requirements the pocket-size
camera has high resistance to shock and vibration.
Simple in design and operation, the camera can be operated
by non-technical personnel.
Molecular Computer
A small computer with molecular blocks as its "brain" is being
developed.
The new device, called a Mol-E-Com, will weigh 14 pounds
and occupy less than one-third of a cubic foot. A solid semiconductor
crystal with its internal structure rearranged as a functional electronic
block replaces the tubes, transistors, and resistors in conventional
miniaturized circuitry.
Mol-E-Com is expected to have the same capabilities as a
transistorized computer ten times its size and weight, making it useful
for rockets
Miniature Computer is size of Bread Loaf
A compact electronic computer about the size of a loaf of
bread, yet capable of working as fast as a room size computer, has
been demonstrated successfully.

All sorts of things are available on the WWW. One can use
Internet for recreational purposes. Many TV and radio stations
broadcast live
17
on the WWW. Essentially, if something can be put
into digital format and stored in a computer, then it's available on the
WWW. You can even visit museums, gardens, cities throughout the
world, learn foreign languages and meet new friends. And, of course,
you can play computer games through WWW, competing
18
with
partners from other countries and continents.
Just a little bit of exploring the World Wide Web will show you
what a lot of use and fun it is.
