Temporary Advisory and Scientific Committee and created many inventions for the soldiers. In 1930 he presented the theory of multiple associations. He also conducted the research on the point of change in the liquid phase and worked on the experimental finding of light molecules. Einstein mentioned his work at the Berlin Academy of Science. In 1936 he checked the electric conductivity of liquid helium and started to organize the institute of low temperature at the Warsaw University of Technology. He also worked on the magnetocalorimetric of liquid helium. In 1937 he found the direct evidence of fulfilment of the law of "action and reaction" for the electrical circuit of any shape. In 1938 he made his final measurements of magnetostriction of liquid oxygen and began researching autoprotonal discharges from palladium hydrogenated anodes. All Wolfke's plans were crossed by the World War II. From his Institute the German soldiers stole the lab equipment. During the occupation, Wolfke led the Research Institute of Technical Physics at the Warsaw University of Technology (which was controlled by the occupier) and had lectures at the Higher State Technical School. He also organized support for the conspiracy and participated in the underground teaching. Before the war, in May 1939, Wolfke wrote an article in the magazine "Polish Armed Forces" which was a warning against Nuclear weapons, and in 1945 he wrote a book entitled "Atomic bomb". During his life he had many opened lectures which were very popular and gathered many listeners. Organizations Mieczysław Wolfke belonged to many different organizations and associations, for example: Prussian Academy of Sciences, Academy of Technical Sciences, Commission of the International Institute of Refrigeration, Warsaw Scientific Society, Polish Physical Society, Polish Academy of Learning in Kraków, Deutsche Physikalische Gesellschaft, Schweizerische Physikalische Gesellschaft, Warsaw Polytechnic Society, Polish Society of Scientific Expeditions, International Cryogenic Commission, French Physical Society, Swiss Physical Society, Polish National Committee of the International Physical Society, Physical Education and Applied Sciences Committee, YMCA and the Grand National Assembly. Awards and honors Mieczysław Wolfke was decorated the Commander's Cross of Polonia Restituta. References 1883 births 1947 deaths 20th-century Polish physicists University of Breslau alumni
