The hunt for the Higgs was the subject of wide media attention due to the cost of the project, the complexity of the experiment, and the importance of its result. And, when it was announced with great fanfare in 2012 that physicists has succeeded in creating and identifying this all-important new particle, the discovery was celebrated around the world.And yet, virtually no one who read that news could tell you what, exactly, the Higgs boson was, and why its discovery was so important that we had to spend 10 billion dollars and build the single largest and most complex device in the history of mankind in order to find it. When you understand the details, this story ranks as one of the most thrilling in the history of modern science.Award-winning theoretical physicist Sean Carroll, a brilliant researcher as well as a gifted speaker who excels in explaining scientific concepts to the public, is perfectly positioned to tell this story. In this 12-lecture masterpiece of scientific reporting, you'll learn everything you need to know to fully grasp the significance of this discovery, including the basics of quantum mechanics; the four forces that comprise the Standard Model of particle physics; how these forces are transmitted by fields and particles; and the importance of symmetry in physics.You also get an in-depth view of the Large Hadron Collider - the largest machine ever built, and the device responsible for finally revealing the concept of the Higgs boson as reality. By the end, you'll understand how the Higgs boson verifies the final piece in the Standard Model of particle physics, and how its discovery validates and deepens our understanding of the universe.

    But building a machine learning system requires that you make practical decisions: Should you collect more training data? Should you use end-to-end deep learning? How do you deal with your training set not matching your test set? and many more. Historically, the only way to learn how to make these "strategy" decisions has been a multi-year apprenticeship in a graduate program or company. This is a book to help you quickly gain this skill, so that you can become better at building AI systems.

    There's a lot for astronomers to be smug about. But when it comes to understanding how the Universe began and grew up we are literally in the dark ages. In effect, we are missing the first one billion years from the timeline of the Universe.This brief but far-reaching period in the Universe's history, known to astrophysicists as the 'Epoch of Reionisation', represents the start of the cosmos as we experience it today. The time when the very first stars burst into life, when darkness gave way to light. After hundreds of millions of years of dark, uneventful expansion, one by the one these stars suddenly came into being. This was the point at which the chaos of the Big Bang first began to yield to the order of galaxies, black holes and stars, kick-starting the pathway to planets, to comets, to moons, and to life itself.Incorporating the very latest research into this branch of astrophysics, this book sheds light on this time of darkness, telling the story of these first stars, hundreds of times the size of the Sun and a million times brighter, lonely giants that lived fast and died young in powerful explosions that seeded the Universe with the heavy elements that we are made of. Emma Chapman tells us how these stars formed, why they were so unusual, and what they can teach us about the Universe today. She also offers a first-hand look at the immense telescopes about to come on line to peer into the past, searching for the echoes and footprints of these stars, to take this period in the Universe's history from the realm of theoretical physics towards the wonder of observational astronomy.

    Weaving together anecdotal narratives and preliminary research on the use of small amounts of psychedelics, Microdosing Psychedelics is oriented toward anyone interested in microdosing to improve their general well-being, particularly those in leadership and creative positions. Over the last few years, microdosing has entered the cultural zeitgeist. From bio-hackers in Silicon Valley seeking to improve their focus, to writers and artists looking for a creative edge, to suburban moms struggling with depression, to everyday people who want to achieve emotional balance, microdosing has led the way in mainstreaming and normalizing psychedelics. In the most comprehensive book of its kind, author, public speaker, and microdosing expert Paul Austin provides a thorough overview of how just about anyone can benefit from an intentional, structured microdosing protocol. In Microdosing Psychedelics, Austin provides readers with everything they need to know about microdosing, including: • What exactly is microdosing and how did it become a “thing?” • How to set up a weekly schedule if you want to experiment with microdosing • Three ways microdosing can benefit your professional career • The safest and easiest ways to obtain psychedelics if you wish to experiment with microdosing

    

    Professor Resnick presents a fundamental and unified development of the subject with unusually clear discussions of the aspects that usually trouble beginners. He includes, for example, a section on the common sense of relativity. His presentation is lively and interspersed with historical, philosophical and special topics (such as the twin paradox) that will arouse and hold the reader's interest. You'll find many unique features that help you grasp the material, such as worked-out examples, summary tables, thought questions and a wealth of excellent problems. The emphasis throughout the book is physical. The experimental background, experimental confirmation of predictions, and the physical interpretation of principles are stressed. The book treats relativistic kinematics, relativistic dynamics, and relativity and electromagnetism and contains special appendices on the geometric representation of space-time and on general relativity. Its organization permits an instructor to vary the length and depth of his treatment and to use the book either with or following classical physics. These features make it an ideal companion for introductory course

    We are introduced to the known particles of the world we live in. An elegant explanation of quantum mechanics and relativity paves the way for an understanding of the laws that govern particle physics. These laws are put into action in the world of accelerators, colliders and detectors found at institutions such as CERN and Fermilab that are in the forefront of technical innovation. Real world and theory meet using Feynman diagrams to solve the problems of infinities and deduce the need for the Higgs boson.Facts and Mysteries in Elementary Particle Physics offers an incredible insight from an eyewitness and participant in some of the greatest discoveries in 20th century science. From Einstein's theory of relativity to the elusive Higgs particle, this book will fascinate and educate anyone interested in the world of quarks, leptons and gauge theories.This book also contains many thumbnail sketches of particle physics personalities, including contemporaries as seen through the eyes of the author. Illustrated with pictures, these candid sketches present rare, perceptive views of the characters that populate the field.The Chapter on Particle Theory, in a pre-publication, was termed “superbly lucid” by David Miller in Nature (Vol. 396, 17 Dec. 1998, p. 642).
