I would avoid this example guys as it centres around the subtle distinction between a mathematical relation and a db-relation. In the former ordering of elements within the tuple does matter (Gene's case) and in the latter it does not due to column names (Marshall's case). i.e. you're both right from a different foundational assumption.
