When it comes to question marks, exclamation points, and dollar signs, I believe there are many People are very familiar with these symbols and often see these symbols in life. However, if you ask about the origin of these symbols and the meaning behind them, not many people may know about them. After all, this aspect of knowledge is still relatively unknown. So it’s understandable that you don’t know, so let me share it with you: There are hidden meanings behind the famous 7 symbols that many people don’t know!
1, USB logo
We are all familiar with USB. It is the Universal Serial Bus, which is responsible for connecting computer systems and external devices. But have you ever noticed the small logo on USB? It looks a lot like a fork. In fact, the symbol is inspired by the Trident of Poseidon. The meaning behind it is that the technology product, like the trident, has perfect power and technical capabilities.
However, although they are very similar, there are still certain differences. For example, the arrow on the USB actually represents the serial data, that is, the bits 1 and 0 that make up all information, while the circle It represents 5V, which is the voltage at which USB works. As for the square logo, it actually represents the ground voltage.
2, infinity symbol
The infinity symbol, also known as the eternity symbol or eternity symbol, was first used in mathematics by John Wallis in the 17th century. It is unclear why Wallis chose this symbol. Exactly why, while its shape does so conveniently represent an endless curve, historians note that similar figures appeared in early Christian iconography, and the ancient Romans used a series of numbers to represent "many," similar to the number 8.
It is worth mentioning that the infinity symbol became a very popular aesthetic trend starting around 2011. It now has meaning beyond the realm of mathematics and is often adapted by others for use in Expressing never-ending love, due to its appeal of simple design and profound meaning, the infinity symbol has become a popular symbol in fashion and accessory design, most commonly in the form of jewelry and Tattoo.
3, dollar sign
There are two theories about the origin of the dollar sign. The first theory is that in the Middle Ages, the most popular currency was the Spanish real, which was regarded as the most popular currency in colonial America in the late 1700s. The basic unit of value, the peso's abbreviated name in the United States was ps. Later, over time, the abbreviation was often written as S on top of the P, resulting in an approximation of the $ sign. The U.S. dollar came into widespread use after the first paper currency was issued in 1875. .
The second theory is that the philosopher Ayn Rand has a chapter about the dollar sign in the 1957 novel Atlas Shrugged. She claims that the dollar sign is not only It is a symbol of the currency of the United States and a symbol of the country's economic freedom. According to Rand, the dollar sign uses two downward slashes instead of one. It comes from the initials of the United States, a capital letter U superimposed on a capital letter S. Minus the lower part of the U, although it sounds reasonable, there is no documentary evidence to support it. However, many Americans still insist that Rand's statement is true!
4, section mark
This symbol is often seen in books. The symbol is composed of double S. Some people do not understand the meaning behind this symbol. In fact, the symbol is a printing Character, primarily used to refer to a specific part of a document, such as a legal code. It is also known as the double "s" or segmentation mark. The segmentation mark may have originated from the Latin signum sectiōnis, a shortened version of the two S letters. It means "section mark"!
5, exclamation mark
Although there is no conclusive evidence to confirm the origin of the exclamation mark, many experts believe that this symbol is likely to come from Latin, because in medieval Latin, the exclamation point for joy was io, where The i is written above the o, and, since they are all capital letters, the I with an o below looks a lot like an exclamation point.
As time went by, the two originally parallel letters changed. The i moved above the o, and the o also became smaller, and finally turned into a dot. , forming the symbol we know well, the exclamation point was first introduced into English printing in the 15th century to express emphasis, and it was not known as a symbol of admiration or exclamation until the mid-17th century!
6, recycling symbol
We can see the recycling symbol in some trash cans or recycling stations. It consists of three green arrows. Why is such a symbol designed? Many people may not know that the original recycling symbol was designed in 1970 by Gary Anderson, a senior student at the University of Southern California.
Submitted to an international design conference as part of a national high school and college competition sponsored by Container Corporation of America and a response to the first Earth Day, the symbol represents a Mobiu The loop is composed of three chasing arrows, in the shape of a triangle with a rounded vertex. Each arrow rotates on its own axis, and the three arrows form a closed loop, which represents the meaning of a recycling cycle.
7, question mark
We are all familiar with the question mark, which represents a language question. However, many people may not know the origin and hidden meaning of the question mark. It is understood that in medieval Latin , people would write "quaestio" at the end of the sentence to indicate that it was a question, and the question word was shortened to "qo", and finally the "o" was placed under the "q" and the "q" became a Hook shape, the "o" also becomes a dot.
In addition, there is another version about the origin of the question mark. Alcuin, an English scholar and poet born in 735, was invited to join the court of Charlemagne in 781. There, Alcuin became one of Charlemagne's chief advisers and wrote numerous books, including some on grammar. In the early Middle Ages, punctuation was limited to a system of points at different levels. Recognizing the limitations of this system, Alcuin Kun created a symbol similar to a tilde or "lightning bolt" to represent the raised tone of voice used when asking a question, which later evolved into the question mark symbol we know today!
