Telegraph and the revolution of network

The nineteenth century opened up a glorious age of long-distance communication with the invention of telegraph by Samuel Finley Breese Morse – the greatest breakthrough in the field of communication. With the telegraph, people could send a message amongst locations for the first time in the history. Within a short period, this invention became so popular that telegraphic cables were stretching to every almost every corner of the world. Its application in rapid communication has even reached further: military orders and information were rapidly sent to distant battlefields; entrepreneurs adjust cost price of goods on the other side of the globe and news were delivering at an unlimited speed to readers around the world, so long as they were linked by telegraphic wires. Therefore, people across the globe were connected with each other via telegraph poles, forming a network society.

As outdated as it seems, the telegraph promoted a revolution in information transmission, with the invention of radio, telephone and recently the Internet. With the advance of technology and information in today’s digital era, the new means of communication have created a global integrated information network, yet many of the core ideas of the telegraph still remain.

Lastly, here is my audio piece quoting Albert Einstein explaining the definition of wireless telegraph in the form of Morse code: “The wireless telegraph is not difficult to understand. The ordinary telegraph is like a very long cat. You pull the tail in New York and it meows in Los Angeles. The wireless is the same, only without the cat”

Thank you and hope you enjoy today’s communication network!
