Smoke Signals

 Native American Indians are not the only group of people who have used smoke signals to communicate.
 
The Chinese have also used smoke signals as well as the Boy Scouts of America.
 
This form of communication is used by creating puffs of smoke using a fire and a blanket.
The smoke signals must be used in an area where they will be visible to the receiver and is usually transmitted atop a hill or mountain.

        Television

 Television is a widely used telecommunication medium for broadcasting and receiving live, moving greyscale or color images with sound.
 
The television has become such an integral part of homes in the modern world that it is hard to imagine life without television.
 
In the late 1800s, Paul Gottlieb Nipkow, a student in Germany, developed the first ever mechanical module of television.
In 1923, an American inventor called Charles Jenkins used the disk idea of Nipkow to invent the first ever practical mechanical television system.
In 1926, just a little after Jenkins, a British inventor known as John Logie Baird, was the first person to have succeeded in transmitting moving pictures through the mechanical disk system started by Nipkow.
 
In 1927, Philo Taylor Farnsworth was able to invent a working model of electronic television that was based on Alan Swinton’s cathode ray tube ideas.

      Censure

 I'm not sad because they steal my ideas, i’m sad because they don't have their own ideas.
Nikola Tesla
 
Intelligence is the capacity to receive, decode and transmit information efficiently.
Stupidity is blockage of this process at any point.
 
Mankind censure injustice, fearing that they may be the victims of it and not because they shrink from committing it.
Censure is the tax a man pays to the public for being eminent.
 
Censorship ends in logical completeness when nobody is allowed to read any books except the books that nobody reads.
Censorship reflects a society's lack of confidence in itself.
It is a hallmark of an authoritarian regime.
 
The first condition of progress is the removal of censorship.
