    Andromeda Galaxy at 100

    In 1924, American astronomer Edwin Powell Hubble (1889-1953) established the distance of the “Great Nebula” in Andromeda, clearly placing it outside the limits of our Milky Way. All of a sudden, the observable universe had just expanded by at least a million times. During beautiful evenings of late summer and autumn, you can observe in […]

    Myths and Open Questions of Quantum Mechanics

    After a hundred years, the field of quantum mechanics still has much to cause us to ponder. Nevertheless, science has progressed, and we know more than we used to know.  Among the things that have progressed are the modern understandings of past experiments in the context of quantum field theory.  Some of the things we […]

    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 […]

    Publication metrics don’t have to drive academia

    Rudolf Weigl, a Polish biologist who invented the first effective vaccine against typhus, called a practice of publishing many papers a ‘duck shit’: just as ducks leave a lot of traces while walking about in the yard, scientists hastily publish articles with partial results that are the product of undeveloped thought. This is one of the unfortunate outcomes of the evaluation game in today’s science, where researchers attempt to follow various evaluation rules and meet metrics-based expectations.

    Black Holes and Galaxies

    More than a century after Einstein formulated General Relativity (GR), black holes are firmly established as one of its most striking and inescapable consequences.

    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.
