... would also be true. A laser is useful because it produces light that is not only of essentially a single frequency but also coherent, with the light waves all moving along in unison. Lasers consist of several components. A few of the many things that the so-called active medium might consist of are, atoms of a gas, molecules in a liquid, and ions in a crystal. Another component consists of some method of introducing energy into the active medium, such as a flash lamp for example. Another component is the pair of mirrors on either side of the active medium which consists of one that transmits some of the radiation that hits it. If the active component in ...
... run around in the front line and fire their guns. Warfare is now totally dependent on sophisticated computer technology in numerous different areas. Examples are the navigation of a submarine and intelligent long-range missiles. What most people associates with computers and war may be various simulation and action games.

... in 1985, came up with the first glove in February 1986. The glove is made of thin Lycra and is fitted with 15 sensors that monitor finger flexion, extension, hand position and orientation. Connected to a computer through fiber optic cables. Sensor inputs enable the computer to generate an on screen image of the hand that follows the operator's hand movements. The glove also has miniature vibrators in the finger tips to provide feedback to the operator from grasped virtual objects. Therefore, driven by the proper software, the system allows the operator to interact by grabbing and moving a virtual object within a simulated room, while experiencing the "feel" of th ...
... thirty feet thick. They also had multiple walls so that if invaders got past the outer wall they still had to get past one or two more, this made defending the castle much easier. The walls were constructed with narrow, wedge-shaped slits in them for archers to shoot arrows at invaders. The outer walls also had holes in the floors for defenders to drop rocks down on invading people who had gotten through the first wall. These holes were called murder holes. Inside the castle were many knights, archers, and soldiers prepared to defend against anyone who breaks all of the way through the walls and gets inside of the castle. Castles also had very large gates an ...

So, specific restrictions must be made on the uses; such as, it must only be used on a life threatening disease or life altering problem.

... Engine. The plans for this engine required an identical decimal computer operating on numbers of 50 decimal digits (or words) and having a storage capacity (memory) of 1,000 such digits. The machine was supposed to operate automatically, by steam power, and require only one person there. Babbage's computers were never finished. After Babbage, there was a temporary loss of interest in automatic digital computers. A strong need thus developed for a machine that could rapidly perform many repetitive calculations. ------------------------------------------------------------------------ Use of Punched Cards by Hollerith A step towards automated comput ...
