The main topic was the idea of signal to noise ratio. The idea is that a signal is something you want to hear while noise is the things that aren’t the signal. For example, if you are listening to a speech being given outside, the words from the speaker are the signal, and any other outside sound is considered noise. A polititian  is someone who can give a bad ratio of signal to noise meaning that the amount of relevant info they say is fa less than the total amount of words they say. During the 1920’s, the radio was starting to emerge as a device of use from Americans. In 1921, the number of people with a radio was extremely low. Then, in 1928, the number of radio owners skyrocketed. In class, we also discussed Boolean Algebra which uses philosophical logic to solve problems rather than numbers. It follows the coding process of, “If ___, then ___.” The video shown was a mouse going through a maze. It was programmed to take in info as it went on in terms of which ways blocked him, and which ways got him to the next step. Each correct step was memorized by the mouse until it was able to complete the puzzle. What is interesting about this is that if the mouse were to be placed again in the same environment, it would complete the puzzle with no wrong movements.
