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.

Presents Galileo's demonstrations translated for the first time from geometry into algebra, a much easier language for modern readers to understand

Addresses anyone who would like really to know Galileo without engaging in a lengthy study: scientists, physicists, philosophers, historians of science, curious readers, technicians/engineers, even hobbyists

Presents a new version of the original Galilei's drawings, digitally restored in collaboration with the Italian National Library in Florence

Is timed to anticipate the 2022 800th anniversary of the foundation of the University of Padua, for which a revival of Galileo can be expected
