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 presents more than 200 problems, with detailed guided solutions, spanning key areas of particle physics and astrophysics. The selected examples enable students to gain a deeper understanding of these fields and also offer valuable support in the preparation for written examinations. The book is an ideal companion to Introduction to Particle and Astroparticle Physics: Multimessenger Astronomy and its Particle Physics Foundations, written by Alessandro De Angelis and Mário Pimenta and published in its second edition in Springer’s Undergraduate Lecture Notes in Physics series in 2018. It can, however, also be used independently. The present book is organized into 11 chapters that match exactly those in the companion textbook, and each of the exercises is given a title to facilitate identification of the subject within that book. Some new exercises have been added because they are considered helpful on the basis of the experience gained by teachers while using the textbook. Beyond students on relevant courses, exercises and solutions in particle and astroparticle physics are of value for physics teachers and to all who seek aid to self-training.

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 is about the 1604 supernova and presents the translation of key documents discussing this astronomical event in Italy. Only seven Galactic supernovae visible to the naked eye are documented, with the 1604 event, the last in history, profoundly impacting astronomy, cosmology, and culture in general.  The 1604 supernova challenged the prevailing belief in the unchanging nature of stars. Astronomers like Galileo and Kepler, alongside counterparts from Arab, Chinese, and Korean backgrounds, collaborated to explain its origin, analyzing astronomical and astrological signals five years before the invention of the telescope. Galileo, approached for interpretation while teaching in Padua, cautiously expressed his views in three unpublished lectures, a pseudonymous treatise written in Paduan dialect, and a poem immediately withdrawn, sparking a dispute with Aristotelian scholars in Italy. The 1604 supernova, a pivotal historical event, spurred collaborative efforts and debates, reshaping perceptions of the cosmos. This debate dominated science from 1604 to 1606, preceding Kepler''s treatise {\em De Stella Nova}. Remnants of the explosion of the supernova, called today Kepler’s supernova, are still visible and are the subject of studies by modern observatories and discussions in the astrophysical community.

This book explores the Galilean method for geolocation, placing it in historical and astronomical context. It bridges the techniques developed by the Greeks and medieval astronomers with later innovations like precision clocks, 20th-century wireless technology, and space-based navigation.

The primary source is the twenty-volume National Edition of the Works of Galileo (published 1890-1909 by Antonio Favaro) and the update edited by Michele Camerota and Patrizia Ruffo in 2019, which includes previously unpublished documents on Galileo''s negotiations with the Spanish government for selling his longitude-determining method at sea.

This book inspired the 2024 "International Research Day in the World," focused on geolocation, organized by the Italian Permanent Delegation to International Organizations in Paris. In collaboration with Museo Galileo in Florence and Sorbonne Université, the event featured the exhibition “Galileo and Satellite Navigation,” showcased at the Pierre et Marie Curie Campus in Paris (June 13-28, 2024), and later at the Italian Institutes of Culture in Prague and Amsterdam, and at the Perimeter Institute in Waterloo, Canada.

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 describe the recent discovery of gravitational waves and astrophysical neutrinos, which started the new era of multimessenger astrophysics; it also includes new results on the Higgs particle. 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. 

This book, written by researchers who had been professionals in accelerator physics before becoming leaders of groups in astroparticle physics, introduces both fields in a balanced and elementary way, requiring only a basic knowledge of quantum mechanics on the part of the reader. 

The new profile of scientists in fundamental physics ideally involves the merging of knowledge in astroparticle and particle physics, but the duration of modern experiments is such that people cannot simultaneously be practitioners in both. Introduction to Particle and Astroparticle Physics is designed to bridge the gap between the fields. It can be used as a self-training book, a consultation book, or a textbook providing a “modern” approach to particles and fundamental interactions.
