My first week of doctoral coursework at Johns Hopkins in 2017 came with four hundred pages of reading. The second week came with five hundred. I had been reading science for a living for a decade — as a journalist, a teacher, a writer — and by the middle of the term it was an […]

Purpose of the book: This book provides an advanced and detailed, yet pedagogical, account of the theoretical formal-ism that describes quantum many-body systems departing from equilibrium under quite generalconditions. It deals specifically with the contour Green’s functions formalism, which is a generaland versatile framework that can be applied to finite and extended quantum many-body systems,whether […]

Subject of the book The book is about systems of random variables, that is, sets of random vari-ables ordered in two ways: by their contents (the questions the variables answer) and by their contexts (conditions under which they are recorded). Such a sys-tem can be contextual or noncontextual. The meaning of contextuality in this book […]

As the International Year of Quantum Science and Technology 2025 marks one hundred years of modern, quantum mechanics this reflection invites readers to look beyond the theory’s extraordinary successes and to consider how we understand, teach, and carry it forward into its next century. When the United Nations proclaimed 2025 the International Year of Quantum […]

Imagine a time when our best images of the universe were black and white photos. This is the year 1960. Forget about galaxy evolution theory, we didn’t even have mature ideas on how they came to exist. We had no idea how the universe evolved, nor how old it might be. As championed by Sir […]

What is life, or are there universal properties of living systems? More than 80 years ago, Schrödinger published his seminal monograph What is Life? in which he predicted the nature of DNA as an information-carrying molecule and discussed the significance of the non-equilibrium nature of biological systems. This book was a physicist’s attempt to elucidate […]

The Rosetta Stone is a famous stone artefact that was found in Rosetta in 1799 with inscriptions written on it in three different languages: Ancient Egyptian, Demotic and Ancient Greek. Given that Ancient Greek was well understood at the time, it helped deciphering the two other languages, most particularly Ancient Egyptian. Why do I tell […]

Summary: A First Course in Magnetohydrodynamics offers a much-needed resource for undergraduate physics education. Despite the fact that magneto-hydrodynamics (MHD) can be used to describe more than 99.99% of the visible universe, it is usually relegated to graduate programmes in plasma physics and almost never taught at the undergraduate level. In this blog post, I […]
