Writing is an unbelievably useful tool to record and communicate ideas. Since writing was first invented, people have attempted to develop writing system of taking down the words of other as rapidly as they were spoken. According to Bledsoe (2011) the average speed of copying is 68 letters per minute (approximately 13wpm), with the range from a minimum of 26 to a maximum of 113 letters per minute (approximately 5 to 20 wpm). People, however, speak at about 150 - 180 wpm, so the scribes who needed to record important speeches were faced with a physical problem of keeping up with what was said. As a result they developed alternative, quicker forms of writing, parallel to the usual full-blown form of writing (which is sometimes called longhand). Another example is Stenography, there are different authors who came up with the different 7 principles and a rule when it comes to stenography, but still stenography is one of the products of intensive research and experimentation.
