Excerpt from an article about famous science dogs. It reads: Not all their participation, however, has been so positive. Sir Isaac Newton loved animals and his closest friend may have been his dog Diamond. Apparently, Diamond was quite smart as well. Newton once told a friend that Diamond had helped him discover 2 theorems in a single morning, although one had a mistake and the other had a pathological exception. Diamond once accidentally knocked over a candle that destroyed years of Newton's work. Newton replied, "O Diamond, Diamond, thou little knowest the damage thou hast done"
