1. THE BLUETOOTH SYMBOL
The Bluetooth symbol is a bind-rune, which means that it is made from two runes that were merged together. Runes are the old Norse letters that, according to mythology, Odin created and gave to gods and humans. Runes have been used for over thousand years and probably much longer.
During the rule of King Harald Blåtand, a past figure famous for combining Danish tribes into a single kingdom. Harald was often called “Bluetooth“ because of his large love of blueberries, which actually left one of his teeth with a permanent blue tint.
2. THE “POWER ON” SYMBOL
The “power“ symbol can be seen on almost any device, but few people know about its roots.
As far as the early 1940s, engineers used a binary system for designing specific switches. 1 indicated on and 0 indicated off. In the following decades, it converted into a circle with a vertical line running through it.
3. THE PEACE SYMBOL
The peace symbol was created in 1956, during the protests against nuclear weapons and war. The symbol was a mixture of the semaphore signals for the letters “N” and “D”, suggesting Nuclear Disarmament.
4. THE HEART
We all partner the love heart with romantic love and affection, and whilst it is not verified, a theory suggests that its shape really derives from silphium, a giant fennel, which was really used as birth control by the ancient Greeks and Romans.
5. THE AMPERSAND (“&”)
The ampersand symbol, which we use for the symbol “and” really has a comparable meaning. It represents the Latin conjunction “et“ which means “and” in English. Such ligature was originally invented in Ancient Rome by Tiro, Cicero’s personal secretary.
