WebThe application of this procedure to the calculation of the Fermi age of H/sub 2/O leads to a value of T = 25.0 cm/sup 2/, which is in very good agreement with the theoretical value of T = 25.3 cm/sup 2/ obtained again and again by other methods. The analysis of the assumptions made in this calculation shows that the above value might be very low. WebAug 29, 2001 · Working alone, between 1919 and 1922, Fermi built up a solid competence in relativity, statistical mechanics and the applications of quantum theory to such a degree that by 1920 the institute director, Luigi Puccianti, invited him to establish a series of seminars on quantum physics.
