...the 20th in the year 2200? I'm thinking: Electricity, World war one, World war two, The Beattles, Bill Gates, (the home computer). None of us will be alive in 2200, but I'm interested in what you think the most powerful things for we Americans happened in the 20th century. List 5 to 10 events. I take this seriously, I'm a 57 year young man, and will consider each answer carefully. Thanks. Ron Couch
