The Morse code
A small presentation of the Morse code, specially designed for kids.
Morse Code is a method of communication, based on text exchange. Like modern-day SMS but in a more primitive form.
It is named after F.B. Morse who was one of the inventors of the telegraph.
The Morse Code consists of long and short signals that can be transmitted in various ways. By electric pulses just like in the Telegraph but also by sound, light even tapping.
It was mainly used in the maritime industry until recent years because signals were easy to be transmitted via radio waves or light signals, sometimes even with the ship’s horn! The best part of this is that the receiver can receive the message almost without any specialized equipment. A trained eye or a skilful ear is enough most of the times to understand the transmitted signal.
To speed up the process of communication, most commonly used letters have shorter codes and rarer ones have longer. Just to save time and exchange the messages quicker.
For example, A, which is heavily used, equals to . – (Which means one short and one long signal) and Z which is rarely used is – – . . (two long signals and two short signals). E, which is the most frequently used letter, is symbolized only with a short signal .
In order to distinguish the letters there is a small pause equal to one long signal in time between the letters and one longer pause, equal to three long signals beween the words ( So the worlds would not get confused either).
The most famous Morse code phrase is S.O.S. which is used for declaring a distress alert, because it has very easy to remember code (Three long signals then three short signals then three long signals again) . . . – – – . . . That was the reason that took the place of the previous distress alert phrase which was C.Q.D. (Come Quick, Danger). But the Morse Code would be – . – . – – . – – . . Imagine of remembering this under stress!
The only rival to the phrase S.O.S. is the phrase S.M.S. . . . – – . . . Which was an sms ringtone of a famous cellphone maker in the 90’s
Despite the difficulty in learning the Morse code it remains the easiest way of sending signals over long distance without any special equipment.
