In spy dramas, people often use their fingers to type Morse code to communicate. Is this really possible in reality?

Impossible. In spy war dramas, the sound or movement produced by tapping with fingers can transmit information and intelligence, and allow surrounding companions to understand the content of the information and intelligence sent by him. It is a complete fantasy. It's a completely eye-catching nonsense gimmick in a spy drama. It’s true that laymen watch the excitement, while experts watch the door! What exactly is Morse code?

Morse code looks very "unusual", but in fact it is not complicated. To put it bluntly, it actually uses different arrangements of long and short electrical signals to represent different letters, digits, punctuation marks, etc. The short signal "beep" is relatively quick, and the long signal "dah" lasts slightly longer. Letters, numbers and punctuation marks are represented by different combinations of "tick" and "dah".

For example, "tick-tick" represents the letter A, "tick-tick-tick" represents the letter B... Another example is "tick-tick-tick" represents the digit 1, and "tick-tick-tick" represents the digit 2... Punctuation Symbols are also represented by different combinations of "tick" and "dah".

In addition, some specific letter combinations can also be used to express special meanings. For example, the most common "SOS" letter combination was actually originally used in Morse code. In other words, the original Morse code was based on the Latin alphabet. To read Morse code, you must first understand English or some other languages ??based on the Latin alphabet. It cannot be realized in reality

Morse code uses a combination of two sounds of ticking to form letters or digits, and then uses a group of digits to form a letter or Chinese character. After a simple calculation, we can know that a Chinese character requires at least 16 ticks to be combined. If it is encrypted, the memory capacity will increase by several orders of magnitude.

Obviously, it is possible for specially trained people to transfer one or two words or alphabetic symbols between agents by typing Morse code, but to reach the level of conversation, one needs to type out The number of ticks is almost astronomical. Secondly, it requires a powerful brain to completely memorize the relationship between ticks and characters, and the correspondence between characters and Chinese characters. Both of these points are almost impossible to achieve.
