Grazie ad avventurosi studi fu possibile dimostrare un secolo fa che parte della radiazione naturale che si osserva sulla Terra è di natura extraterrestre: era la scoperta dei cosiddetti “raggi cosmici”, particelle che arrivano da misteriosi acceleratori nell’universo, probabilmente buchi neri supermassicci e resti di supernova, a energie anche centinaia di milioni di volte di quelle a cui riusciamo a produrle con i più potenti acceleratori della Terra. A cent’anni dalle prime scoperte questo libro si propone, con l’aiuto di documenti scoperti recentemente, di raccontare la vera storia di questa appassionante avventura scientifica e le frontiere dell'esplorazione dei raggi cosmici.

In recent years, cosmic rays have become the protagonists of a new scientific revolution. We are able today to film the Universe with telescopes of completely novel conception, recording information from many different messengers and accessing previously unknown cosmic regions. Written by a recognized authority in physics, this book takes readers on a captivating journey through the world of cosmic rays, their role in the revolutionary field of multi-messenger astronomy, their production from powerful accelerators close to the surfaces of black holes and compact objects, reaching the highest levels of energy observed in nature, and the implications this has for our understanding of the Universe. Through the stories of pioneering scientists, explorations of cutting-edge technologies, and simple explanations related to particle physics, quantum mechanics, and astrophysics, the book provides an illuminating state-of-the-art introduction to the current state of high-energy astrophysics. The book was written in straightforward yet rigorous language, so as to be accessible to the greater public. For those curious about the cosmos and cosmic gamma rays, nuclei, neutrinos, and gravitational waves, from casual observers to professional astronomers and physicists, the book is a must-read, offering a thrilling adventure into the future of astronomy and particle physics.

This book aims to make Galileo Galilei (1564-1642) accessible to the modern reader by refashioning the great scientist's masterpiece "Discourses and Mathematical Demonstrations Relating to Two New Sciences" in today's language. Galileo Galilei stands as one of the most important figures in history, not simply for his achievements in astronomy, physics, and engineering and for revolutionizing science and the scientific method in general, but also for the role that he played in the (still ongoing) drama concerning entrenched power and its desire to stifle any knowledge that may threaten it. Therefore, it is important that today's readers come to understand and appreciate what Galilei accomplished and wrote. But the mindset that shapes how we see the world today is quite different from the mindset -- and language -- of Galilei and his contemporaries. Another obstacle to a full understanding of Galilei's writings is posed by the countless historical, philosophical, geometrical, and linguistic references he made, along with his often florid prose, with its blend of Italian and Latin. De Angelis' new rendition of the work includes translations of the original geometrical figures into algebraic formulae in modern notation and allows the non-specialist reader to follow the thread of Galileo's thought and in a way that was barely possible until now.

This book introduces particle physics, astrophysics and cosmology. Starting from an experimental perspective, it provides a unified view of these fields that reflects the very rapid advances being made. This new edition has a number of improvements and has been updated to include material on the Higgs particle and to describe the recently discovered gravitational waves. Astroparticle and particle physics share a common problem: we still don’t have a description of the main ingredients of the Universe from the point of view of its energy budget. Addressing these fascinating issues, and offering a balanced introduction to particle and astroparticle physics that requires only a basic understanding of quantum and classical physics, this book is a valuable resource, particularly for advanced undergraduate students and for those embarking on graduate courses. It includes exercises that offer readers practical insights. It can be used equally well as a self-study book, a reference and a textbook. .
