 History

Searching for exact temperature measurements.

Galileo Galilei discovered this fascinating method.     

Galilei put 5 exactly weighted balls in a cylinder filled

with a special liquid.The balls go up or down according 

to the existing temperature. By this method you can 

determine the temperature.    

 Temperature indication

 

In liquid,a solid body with the same weight and size is

compelled to go down as the temperature rises,on the

other hand the solid body goes up in the liquid if the

temperature falls.The glass balls differ in weight and 

floating balls in the upper part of the cylinder indicates

the right temperature.
