These unusual thermometers contain colorful orbs which rise and fall to indicate the current temperature. Crafted of high quality glass and individually calibrated to achieve an accuracy of 2¡F, these thermometers are timeless works of art. The tag on the lowest sphere in the top group indicates the current temperature. Galileo Galilei (1564 - 1642) was an Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution. His findings provided the framework for Newton's laws of motion and Einstein's theory of relativity. His discovery that the density of a liquid changes in proportion to its temperature, inspired the invention and explains the accuracy of the "Galileo Thermometer".
