In recent years scientists have found that the laser has a wide variety of applications, making it one of the most important inventions for improving our quality of life.
One important field in which the laser has many applications is communications. Scientists have found that the laser beam can transmit human voices; as a result, telephone companies are now using laser light signals to transmit telephone calls through extremely small cables that are capable of carrying many more transmissions than the standard telephone cables. An additional advantage is that these systems using the laser light signals are also able to transmit video telephone conversations.
Another, perhaps less-known, field in which lasers are helping improve the quality of life is metrology—the science of measurement. The extremely straight, narrow laser beam can be used to put the parts of a structure being built into the correct position to each other

A Separate Legal Entity
A unique feature of a
company is that, no matter how many individuals have bought shares in it, it is
treated in its dealings with the outside world as if it was a person in its own
right. It is said to be a separate legal entity. Just as the law can create this
separate legal person, the law also can eliminate it, but its existence can only
be terminated by using the proper legal procedures.
Thus, the
identity of the shareholders in a large concern may be changing constantly as
shares are bought and sold by different people. On the other hand, a small
private company may have the same share
