Quantum mechanics—one of the most puzzling and fascinating areas of modern science—has captivated both physicists and the public for over a century. From Einstein’s skepticism about its strange implications to the mysterious behavior of particles that seem to communicate instantaneously across vast distances, quantum theory constantly challenges our understanding of the universe. In my new […]
Read MoreThe General Theory of Relativity (GTR), enunciated just over a hundred years ago by Albert Einstein, remains to this day the best available description of gravitation, the feeblest out of the four fundamental interactions and, nonetheless, the one which shapes and governs the natural world at the grandest scales. Especially in recent decades, empirical evidence […]
Read MoreThis year’s Nobel prize in physics was awarded to John Hopfield and Geoffrey Hinton for `foundational discoveries and inventions that enable machine learning with artificial neural networks´(press release of the Royal Swedish Academy of Sciences, October 8, 2024). Machine learning algorithms with artificial neural networks excel at image analysis, locating and classifying objects in digital […]
Read MoreIn 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 […]
Read MoreAfter 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 […]
Read MoreWhat 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 […]
Read MoreI 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 […]
Read MoreMore than a century after Einstein formulated General Relativity (GR), black holes are firmly established as one of its most striking and inescapable consequences.
