    Quantum measurement book blog

    What is the topic of the book? Measurement is one of the most fascinating and misunderstood aspects of quantum physics. It plays no role in classical physics, other than reducing ignorance about the underlying reality. In quantum physics measurement plays a fundamental role, and the choice of what kind of measurement you choose to do […]

    Theory of liquids, the hard problem

    I had a memorable library day trying to find an answer to a question that is simple to formulate: what is a theoretical value of energy and heat capacity of a classical liquid? I looked through all textbooks dedicated to liquids as well as statistical physics and condensed matter textbooks in the Rayleigh Library at […]

    Relativity applications in radiation and plasma physics

    Albert Einstein developed the theory of relativity using ``thought experiments’’ to illustrate the consequences of a constant speed of light. Many measurements have validated Einstein’s work, but some thought experiments and applications of relativity have only become possible in reality with advances in technology.

    Jean-Baptiste Biot, founder of the scientific study of meteorites

    Four years ago, when I began to write From Crust to Core, A chronicle of deep carbon science, the astrophysicist in me looked forward to documenting the story of how Earth’s carbon originated long ago in stellar explosions. Carbon is the fourth most abundant element in the universe. On Earth it is ranked only fifteenth […]

    Fine-Tuning in the Physical Universe

    We only have one universe. On the face of it, the existence of life, complexity, and structure in our universe seems to be lucky or to call out for explanation. When we look more closely, the physical causes of these important phenomena appear to be balanced on a knife-edge. Fine-Tuning in the Physical Universe formulates these questions and explores the answers in the context of many sub-disciplines of physics.

    Evaluating An Alternative Cosmology

    David Merritt, author of PROSE Award winning book "A Philosophical Approach to MOND: Assessing the Milgromian Research Program in Cosmology” discusses the competing theories of MOND and LCDM ‘Suppose that the dark-matter detection experiments continue to fail. How can we hope to ever decide between the two competing theories?’
