Obsessive Or Careful?

Once I spent the week at the house of a nuclear physicist. Dick had just gotten a new automatic drip coffee maker, so that week was testing week. Each morning, Dick took out the coffee, a gram balance, a graduated cylinder, and a small notebook. He weighed out the coffee and noted the weight. He then measured the water and noted the volume. He brewed it, poured out a cup, and made tasting notes.
