The measurement of values is fundamental in science and technology. Not only does this book include the importance of uncertainty, accuracy and precision of measurement, it also explains how laser technology has helped improve measurement and redefine standards. Masatoshi introduces the concept of the measurement uncertainty in both a qualitative and quantitate manner, whilst including key equations and formulae. It discusses the SI units, standards and the importance of using lasers for measurement in modern metrology, including the redefinition of SI units over time; which culminated in the agreement to redefine the Kilogram, which takes effect in May 2019. Real case studies are included, from the implications for measuring times at the Olympics, to the impacts in criminal investigations.

Modern physics is the branch of physics that emerged in the late 19th and early 20th centuries, revolutionizing our understanding of the fundamental laws governing the universe at both the smallest and largest scales. It encompasses quantum mechanics, relativity, nuclear physics, particle physics, astrophysics, and cosmology. This book is aimed at undergraduate and graduate students, introducing them to the mysteries of modern physics. Throughout this book, we minimize the derivation of equations, allowing readers to develop intuitive understandings of these concepts. By shedding light on the unsolved mysteries of modern physics, we aim to reveal how the progress of experimental technology not only solves existing puzzles but also uncovers new ones.

This book introduces the preparation, measurement and properties of ultra-cold atoms and molecules at a level accessible to advanced undergraduate students or for researchers approaching the subject from different specialities. Including a review of cooling techniques, the book focuses on the behaviour and applications of both ultra-cold atoms and molecules, and how they are shaping research in atomic physics, quantum optics, condensed matter physics, statistical mechanics, quantum information processing, quantum simulators and finding applications in ultra-high-precision atomic clocks and quantum metrology. Readers of this book should develop an understanding of the techniques used to cool, trap, manipulate and perform measurements on ultra-cold atoms and molecules, as well as how such systems are in being used in a range of exciting areas of modern physics.
