I learned about four inventions this week and they were the telephone, the carpet sweeper, phonograph, and motion pictures. First, I learned about the telephone. Alexander Graham Bell, born in Scotland in 1847, was inspired by his mother’s deafness to study acoustics. Telephones allow people to talk to each other remotely. Federal government broke up AT&T’s monopoly in 1982 and then the baby bells merged back into each other.

Second, I learned about carpet sweeper. Melville Bissel, born in New York in 1843, opened own grocery store and then recession struck in 1873. Sweepers are mechanically powered vacuums that have brush roller and trash reservoir. Bissell’s sweeper led to the vacuum and then robots like roombas came along.

Third, I learned about the phonograph. Thomas Edison, born in Ohio in 1847, was trained by his mother to be a self learner. Today, the phonograph is called a record player. It marks waveforms into disc surfaces. It created the audio entertainment industry and vinyl records are still sold today. 

Finally, I learned about motion pictures. Edward Muggeridge, born in England in 1830, became a photographer in the 1860s. Motion pictures give fast moving images an appearance of motion and one movie is equal to 10,000 feet of the film. Hollywood was controlled by entrepreneurs of Christian movies and modern R-rated films assaulted.
