After that we relaxed by watching two videos relating to Quantum Mechanics and Dark Matter. Quantum Mechanics is the study of the very small which is nevertheless surrounded by large areas of space and not subject to the forces of gravity. We know Dark matter makes up a large percentage of the universe but we have not yet been able to prove its existence. Neither of these subjects are part of our normal discourse but are important matters which in time will eventually have to be understood by everyone. By listening to lectures we hope in time we will gradually begin to comprehend.
We finished up by watching a video on the History of the Sydney Opera House. The Sydney Opera House took a long time to build, was the subject of many Political battles and was often used as a political football. It is, however, an example of both style and substance. It is undoubtedly a Work of Art that was fortunately not destroyed by the government's desire to finish the job as soon as possible after they dispensed with the services of the Architect.
