When I arrived at the office this morning, I noticed that the coffee machine had been replaced with a much more complex model. I was unable to make a coffee, and I am a professional mathematician, so I was quite disappointed. The new cups also seemed different - they were smaller and had a different shape. They are made of plastic and have a small hole in the middle of them... I would love to know what the reasoning behind this change was, and whether or not it will have any impact on my productivity.
