1. His contributions are in the areas of nanoscience, ultra-low temperature physics , and quantum effects. 2. Among his research specialties were high frequency sound waves in liquid and low temperature physics . 3. His thesis was in experimental low temperature physics . 4. He was involved with experimental low temperature physics . 5. In 1992 he became co-editor of the Journal of Low Temperature Physics , and in 2014 honorary editor. 6. This device is still used, based on their original design, in other labs dealing with low temperature physics . 7. :: : Helium-3 isn't " that " rare-people do low temperature physics using refrigerators running He 3 for example. 8. He was Professor of Physics, Cambridge University and Head of Low Temperature Physics Group, Cavendish Laboratory, 1973 78, then Professor Emeritus. 9. A review of this work appears in the chapter written for the 1967 " Progress in Low Temperature Physics " together with Mamaladze. 10. He then joined the Max Planck Institute for Metals Research in Stuttgart, where he worked on solid state physics and low temperature physics .
