Nuclear Physics 3 presents the applications of various radioisotopes in nuclear medicine, with a focus on radiological imaging methods such as X-rays, γ scintigraphy – PET – MRI and ultrasound, which do not exploit the properties of radiopharmaceuticals. The book then presents the physicochemical and pharmacological properties of radiopharmaceuticals labeled with 99mTc, 201Tl, 18mKr, 18F and the radioisotopes 123I, 125I and 131I used in nuclear medicine. The production chains for the radiotracers studied, as well as their main emissions, are then described in detail, followed by a study of the clearance mechanisms of the radiopharmaceuticals under consideration. Finally, the book describes the principles of myocardial, pulmonary, bone, thyroid, renal and gastric emptying scans using the properties of the radiotracers studied, as well as the principles of prostate brachytherapy using iodine-125 implants and prostate chemotherapy.

Nuclear Physics 2 explores the applications of various radioisotopes for dating and nuclear medicine imaging. It introduces the theoretical and experimental facts from the observation of the red shift in the spectrum of galaxies (1913), and the discovery of the cosmic microwave background (1965) that led to the validation of the Big Bang model, through which all known chemical elements are created via nucleosynthesis processes. This introduction is followed by a description of the nuclear reactions involved in primordial, stellar, and explosive. The principles of carbon-14, potassium-argon, uranium-thorium and uranium-protactinium dating, along with the principles of lead-210, caesium-137 and beryllium-7 radiochronometers applied to dating, are also described. An overview of the birth of nuclear medicine is given, from the first use of radioisotopes as tracers in plant biology in 1913, to the development of Positron Emission Tomography (PET) in 1975. The method of synthesis of radiopharmaceuticals, quality control of radiopharmaceuticals and the experimental methods of the determination of radiochemical purity are presented. The description of the principles of PET and Single-Photon Emission Tomography (SPECT), the presentation of the different radioisotopes used in TEMPS and PET, as well as the presentation of the main scintigraphies and their uses in nuclear medicine conclude the topics studied.

This book reviews the interconnection of cosmology and particle physics over the last decade. It provides introductory courses in supersymmetry, superstring and M-theory, responding to an increasing interest to evaluate the cosmological consequences of these theories. Based on a series of extended courses providing an introduction to the physics of the very early universe, in the light of the most recent advances in our understanding of the fundamental interactions, it reviews all the classical issues (inflation, primordial fluctuations, dark matter, baryogenesis), but also introduces the most recent ideas about what happened at the Big Bang, and before.

A l'âge de 8 ans, mon fils Quentin a commencé à me poser de nombreuses questions sur l'existence de notre terre, du soleil, des étoiles... mais aussi des questions « toutes simples » sur le monde qui nous entoure : « pourquoi la Lune ne tombe pas sur la Terre ? », « pourquoi le Soleil brille ? », « c'est quoi l'Univers ? », « pourquoi les aimants s'attirent ou se repoussent ? »...A ma grande surprise, je me suis aperçu que j'étais non seulement incapable de répondre clairement et simplement à ses questions mais qu'en plus j'avais oublié toutes mes connaissances acquises pendant mes longues études scientifiques ! Pour lui répondre, j'ai donc acheté plusieurs ouvrages et consulté une multitude de sites Internet sur le sujet mais hélas aucun ne répondait à mes besoins : trop techniques, trop compliqués, pasassez pédagogiques...L'objectif de ce livre est donc avant tout d'expliquer simplementaux petits et aux grands la magie de notre monde : c'est quoi lalumière ? la matière ? l'univers ? le temps ?

This volume provides a detailed description of some of the most active areas in astrophysics from the largest scales probed by the Planck satellite to massive black holes that lie at the heart of galaxies and up to the much awaited but stunning discovery of thousands of exoplanets. It contains the following chapters: • Jean-Philippe UZAN, The Big-Bang Theory: Construction, Evolution and Status • Jean-Loup PUGET, The Planck Mission and the Cosmic Microwave Background • Reinhard GENZEL, Massive Black Holes: Evidence, Demographics and Cosmic Evolution • Arnaud CASSAN, New Worlds Ahead: The Discovery of Exoplanets Reinhard Genzel and Andrea Ghez shared the 2020 Nobel Prize in Physics “for the discovery of a supermassive compact object at the centre of our galaxy’”, alongside Roger Penrose “for the discovery that black hole formation is a robust prediction of the general theory of relativity”. The book corresponds to the twentieth Poincaré Seminar, held on November 21, 2015, at Institut Henri Poincaré in Paris. Originally written as lectures to a broad scientific audience, these four chapters are of high value and will be of general interest to astrophysicists, physicists, mathematicians and historians.

Numerical simulation is a technique of major importance in various technical and scientific fields. Used to understand diverse physical phenomena or to design everyday objects, it plays a major role in innovation in the industrial sector. Whilst engineering curricula now include training courses dedicated to it, numerical simulation is still not well-known in some economic sectors, and even less so among the general public. Simulation involves the mathematical modeling of the real world, coupled with the computing power offered by modern technology. Designed to perform virtual experiments, digital simulation can be considered as an "art of prediction". Embellished with a rich iconography and based on the testimony of researchers and engineers, this book shines a light on this little-known art. It is the first of two volumes and focuses on the principles, methods and industrial practice of numerical modeling.
