Galileo Galilei, the pioneer of modern physics and astronomy, never could have imagined that the remarkable thermometer he invented four centuries ago would become one of the most attractive, intriguing, eye-catching gift items today. To look at a glass Galileo Thermometer is to behold not only an instrument that tells the precise temperature but also a work of beauty and art. The Galileo Thermometer is a conversation piece that leaves a lasting impression. Few other gift items meld design and concept so effectively.
