We briefly discussed what Jared had discovered about the Michelson-Morley experiment, and I was very happy to see that he had researched the subject and had some very relevant questions pertaining to it. We then discussed experimental errors in a larger context (e.g. the consequences of having to combine the signal from multiple elements in an array, such as a radio telescope interferometer) and talked about how propagating errors need to be taken into account. We concluded by discussing the difference between a layman's interpretation of 'probability' and an experimentalist's, or a statistician's.
