Show Records Millionth Degree Temperature Change IViY - " - --.Ml """"" ' " ' ; i J Chemists at Northwestern university, Evanston, III., have invented an instrument that will measure temperature tem-perature changes down to a millionth of a degree. This micro-calimcter can measure the amount of heat produced when sugar dissolves in water. The temperature changes are recorded on a scale so enlarged that one degree would equal a mile. Photograph shows Dr. Hugh Pickard at the recording chart as Professor Frank Gucker studies the sealed vessels used in an experiment. The other inventor is Dr. Ralph Planck. |
