Archimedes and the Archimedes Principle

Archimedes and his Principle. When a barge full of scrap iron sinks in a canal lock, does the water in the lock rise or fall? When the dirigible Hindenberg burned disastrously in Lakehurst, NJ in 1937, how much hydrogen burned and how much energy was released? Charlie Holbrow discusses these questions and much more about Archimedes and his principle, to the Lexington Computer and Technology Group's May 3, 2023 meeting.
