From the Heart
Louise Gibson

"Necessity is the Mother of Invention" There is nothing complicated about a cat door. It was a cat who constantly interrupted his work that Newton designed the door for. Newton was one of history's greatest mathematicians and theorists, whose work demanded full concentration- But his pets, who competed for attention were a constant source of aggravation. Historical Footnote: During his lifetime, Newton made numerous contributions to science, including developing the laws of celestial mechanics, codeveloping calculus, and conducting groundbreaking work on everything from the nature of light spectra to measurements of the speed of sound. But few realize that Newton was also a pet lover, or that sometimes his numerous animal friends could drive him to distraction. For instance, he once suffered an emotional breakdown when a favorite dog knocked over a candle on his desk, burning some of his important research notes. Frustrated, the scientist designed and implemented a solution-- the pet door. Today, every feline blessed with the ability to enter and leave a room without troubling his or her human friends has Newton (and his restless charge) to thank.
