When American Astronomer Clifford Stoll speaks, you can’t really help yourself but listen. He may look and sound like a total nutcase, but take the time to listen to what he has to say, you’ll be glad you did. For the next 18 minutes, you’ll be listening to Mr. Clifford as he talks about things such as the atmosphere of Jupiter, computers in classrooms, KGB hackers, and many, many other things. Asking a men such as him to stay focused on a single subject would be pure folly, because as he says: “Once I do something, I want to do something else.” Enjoy the presentation!
