Here are three i will reflect on!
Cave paintings-Aurignacian, 33,00- BCE
The earliest European cave paintings date to the Aurignacian, some 32,000 years ago.The purpose of the paleolithic cave paintings is not known. The evidence suggests that they were not merely decorations of living areas, since the caves in which they have been found do not have signs of ongoing habitation. Also, they are often in areas of caves that are not easily accessed. Some theories hold that they may have been a way of communicating with others, while other theories ascribe them a religious or ceremonial purpose.
Telephone-, Sweden, 1896
:
.
The telephone , often colloquially referred to as a phone, is a telecommunications device that transmits and receives sound, most commonly the human voice. Telephones are a point-to-point communication system whose most basic function is to allow two people separated by large distances to talk to each other. It is one of the most common appliances in the developed world, and has long been considered indispensable to businesses, households and governments. The word "telephone" has been adapted to many languages and is widely recognized around the world
Pictograms-Sumerian,6000-5000 BC
Pictographs can also take the form of diagrams to represent statistical data by pictorial forms, and can be varied in color, size, or number to indicate change. Pictographs can often transcend languages in that they can communicate to speakers of a number of tongues and language families equally effectively, even if the languages and cultures are completely different. This is why road signs and similar pictographic material are often applied as global standards expected to be understood by nearly all.
