At that time, Fermi was mainly engaged in theoretical work, but he was also interested in experimental work. His creative research is like a printing press, which always works slowly at a single speed, but the results are always clearly expressed in a simple and natural way. Fermi's down-to-earth scientific research style and concise teaching skills have a far-reaching impact on his students.
Fermi will not assign or prompt students for doctoral thesis topics. He expects them to choose their own topics, so as to cultivate their ability to work independently. The academic activities of the Roman School attracted young physicists from all over Italy, and many scholars came to visit them, including B Rossi, G Raqqa, G Vic, E Fubini, U Van O and so on. German scholars also visited the United States before taking refuge, including Bert, Lassek, Bloch, Pailes, Nadheim, London and others.
1929 the Roman school has realized that although their theoretical work has made a good start, their experimental work needs to be strengthened urgently. In order to introduce new experimental skills to Rome, Lasetti first went to the American R·A· Millikan laboratory to study Raman spectroscopy, and then went to the German L Maitenaz laboratory to study nuclear technology. Segre first went to P Zeeman Laboratory in the Netherlands to study the forbidden spectral lines, and then worked in 0 Steen Laboratory in Amar. X-ray liquid diffraction is studied by P.J.W debye laboratory in Germany. After Lasetti came back, the main experimental work of the Roman school shifted from spectroscopy to nuclear physics.
The appearance of quantum mechanics makes Fermi and Cochino feel that the basic problems of atomic physics have been solved, and the future development will be to explore the nucleus and more complex structures, and finally solve the basic problems of life science. 193 1 year, at the instigation of Fermi and Copinot, the Italian Academy of Sciences held a conference on nuclear physics in Rome, which made the Roman school familiar with the popular nuclear problems at that time. Fermi was invited to give a summary report on nuclear physics at the Paris Conference held in 1932. Since then, the main research of the Roman school has entered nuclear physics.
On the eve of World War II, 1938, Lasetti, segre and Amadi, the essence of Fermi school, had already worked in Columbia University before Fermi. After World War II, Fermi taught at the University of Chicago and a large number of graduate students in Rome, some of whom later became famous, such as H.M. agnew, M. gherman, 0 Chamberlain, C. Qiu, M. Goldberger, L. Rosenfeld, Woods and later. Therefore, Chicago has become a busy activity center in all fields of physics. It can be said that the spirit of the Roman school has been revived in Chicago.
