Galileo Galilei’s “Two New Sciences”

Alessandro De Angelis is a high energy physicist and an astrophysicist. A professor at the Universities of Padua and Lisbon, he is Principal Investigator for the proposed space mission ASTROGAM and, for many years, has been Director of research at the Italian National Institute for Nuclear Physics, and Scientific Coordinator and Chairman of the board managing the MAGIC gamma-ray telescopes on the Canary Island of La Palma. His main research interest is in fundamental physics, especially astrophysics and elementary particle physics in accelerators. He graduated from Padua, was employed at CERN for seven years in the 1990s, ending as a staff member, and was later among the founding members of NASA's Fermi gamma-ray telescope project. His original scientific contributions have mostly been related to quantum chromodynamics, artificial neural networks, and the study of the cosmological propagation of photons. He has taught astro-particle physics in Italy and Portugal and has been a visiting professor at the Universities of Buenos Aires, Tokyo, Paris VI, and at the the Max-Planck Institute in Munich. He has been author of books, scientific publications in journals including Science and Nature, popularization articles, and essays in the history and philosophy of science.
