The Galileo Thermometer

Searching for the exact temperature measurements, the brilliant Galileo Galilei made a fascinating discovery. When floating in liquid, a solid object of a standard density, size and weight will "float" up or down within the liquid as the temperature rises or falls.

Galileo created different glass spheres that differed in weight and density of the liquid inside each small sphere. As the interior temperature of each sphere changed, the lowest of the floating spheres in the upper part of the cylinder indicates the correct temperature. To make temperature identification easy, each small floating sphere has a temperature indicating medallion attached.

Today we have carefully reproduced the original Galileo Thermometer concept in a beautiful design to compliment any home or office. The production of this instrument is extremely complicated. Each temperature ball is calibrated to exactly .36 degree F. Two glass spheres differ in weight by only 6/1000 of a gram. Temperatures are marked in Fahrenheit.

Gem of the Day™ is offering this very unique gift in three sizes. All three sizes contain multi-colored temperature spheres to indicate the temperature. The small and medium sizes have five temperature spheres, marking the temperature in 4 degree increments. The Large model has seven temperature spheres, each set at a two degree increment. All are made for indoor temperature measurement and direct sunlight or heat should be avoided.

Galileo Galilei Galileo Galilei was born February 15, 1564. Galileo is best known for is his studies of astronomy, free fall, and his several inventions. His inventions include a telescope, microscope, compass and thermometer. Galileo studied medicine, philosophy and mathematics. Galileo taught mathematics at the University of Pisa and at the University of Padua. While teaching his theories, Galileo gained a following of students that recognized his genius. In 1616 however, he came into disfavor with the church. Galileo expressed his support of the Copernican theories that stated the earth and other celestial bodies rotated around the sun. This conflicted with the teachings of the church and he was called to Rome and reprimanded for his "heresy". Galileo was branded a heretic by the church in 1633 and sentenced to life in confinement. By this time, his health was declining. He was completely blind by 1638. He continued developing his theories with the aid of his followers, but eventually died in Arcetri in 1642. Over 300 years after his death, a statement by the Pope before the Pontifical Academy of Sciences in 1992 is interpreted as the official rehabilitation of Galileo by the Catholic Church.
