CERN is the world's largest particle physics research laboratory. Since it was established in 1954, it has made an outstanding contribution to our understanding of the fundamental particles and their interactions, and also to the technologies needed to analyse their properties and behaviour. The experimental challenges have pushed the performance of particle accelerators and detectors to the limits of our technical capabilities, and these groundbreaking technologies can also have a significant impact in applications beyond particle physics. In particular, the detectors developed for particle physics have led to improved techniques for medical imaging, while accelerator technologies lie at the heart of the irradiation methods that are widely used for treating cancer. Indeed, many important diagnostic and therapeutic techniques used by healthcare professionals are based either on basic physics principles or the technologies developed to carry out physics research. Ever since the discovery of x-rays by Roentgen in 1895, physics has been instrumental in the development of technologies in the biomedical domain, including the use of ionizing radiation for medical imaging and therapy. Some key examples that are explored in detail in this book include scanners based on positron emission tomography, as well as radiation therapy for cancer treatment. Even the collaborative model of particle physics is proving to be effective in catalysing multidisciplinary research for medical applications, ensuring that pioneering physics research is exploited for the benefit of all.

The detection of gravitational waves has ushered in a new era of gravitational wave astronomy and added a new medium to multi-messenger astronomy. This book examines the theoretical foundation of gravitational waves and the state of the art of gravitational wave detection including interferometric detectors and pulsar timing arrays. The design and sensitivity of the LIGO interferometers are examined. The source and data analysis method for each of the four main classes of gravitational waves (compact binary coalescence, burst, continuous, and stochastic) are described. A summary of the gravitational waves that have been detected as of January 2019 is presented along with what gravitational wave astronomy has been extracted from these observations. Finally, what the future of gravitational wave exploration looks like in terms of ground-based and space-based detectors is presented.

With the discovery of the Higgs boson our picture of the subatomic world--the Standard Model--is complete. But looking at the Universe on a larger scale, there are things the Standard Model cannot explain, including gravity, dark matter and several others. The Standard Model must be just part of a larger picture, and one of the most obvious places to look for evidence of this larger picture is the biggest experiment studying the subatomic world: the Large Hadron Collider (LHC). The first part of this book describes an example of how the experiments at the LHC search for new particles. I'll be focusing here on the two 'general purpose' experiments: ATLAS (of which I am a member) and CMS. Searches remain central to the work of these two experiments, but the data so far have not revealed any surprises and there is increased interest in making sure we haven't missed something along the way: new discoveries may lie in unconventional signatures, or perhaps we simply haven't had the right idea yet. The rest of book will focus on what some of these unconventional signatures are, and how we are making our ongoing measurements and searches 'future-proof'--i.e., being able to use measurements we make today to test any new ideas that are developed in the future. The rest of book will focus on these two areas.

Quantum computer technology is progressing rapidly with dozens of qubits and hundreds of quantum logic gates now possible. Although current quantum computer technology is distant from being able to solve computational problems beyond the reach of non-quantum computers, experiments have progressed well beyond simply demonstrating the requisite components. We can now operate small quantum logic processors with connected networks of qubits and quantum logic gates, which is a great stride towards functioning quantum computers. This book aims to be accessible to a broad audience with basic knowledge of computers, electronics and physics. The goal is to convey key notions relevant to building quantum computers and to present state-of-the-art quantum-computer research in various media such as trapped ions, superconducting circuits, photonics and beyond.
