Then came the revolution of writing. This enabled greater spreading of language across time and space. It also lead to a decrease in the abilities of the oral story-tellers. In the process, it also changed the way that we think about the world. Different means were used to record speech, including pictographs, syllabaries and alphabets.
The telegraph was one of the first modern technological advancements that enabled widespread communication. However, this in essence simply mirrored African drummers that were able to "talk" with their drums over great distances. Telegraphs required translation of speech into a digital code of "dots, dashes, short pauses and long pauses". Associated with this codes were different additional codes to "encrypt" and "compress" the information via codebooks or other shorthand phrases.
The telephone started to allow communication with analog signals. This set off a revolution where everybody could use the long-distance communicator without an intermediary. From there, the information revolution took off into high gear and never really stopped, with computers, internet and more enabling rapid communication.
This book covers all the communication and the theory behind it. Information theory, mathematics, biology, computer science and more are all covered. It even "jumps the shark" to talk about "jumping the shark". With a topic as broad as "information" it is easy to meander into all sorts of different areas from DNA to the Enigma machine. A little more focus would have been helpful. At times it can get awfully boring as the author rambles on about some topic. Then it can turn around an start to cover something interesting.
