One of the persistent difficulties in discussing the emergence of macroscopic irreversibility from microscopic quantum dynamics is that we often talk about “macroscopic states”, “macroscopic operat…

Bayes’ rule is often introduced in textbooks through examples involving urns filled with colored balls. It is striking, however, that the same formula works just as well in situations totally…

This book is a philosopher's introduction to the idea that our universe is just one of many universes. I present and assess three versions of the idea: one version from philosophy, and two from physic...

To understand the emergence of macroscopic irreversibility from microscopic reversible dynamics, the idea of coarse-graining plays a fundamental role. In this work, we focus on the concept of macrosco...

We introduce a definition of coarse-grained entropy that unifies measurement-based (observational entropy) and max-entropy-based (Jaynes) approaches to coarse-graining, by identifying physical constra...

Commercial platforms and social media companies are designed to maximise switching costs in order to retain users. Reflecting on the rise of Bluesky, Mark Carrigan warns the same market dynamics co…

Emergence, a word whose Latin roots are ex = "out" + mergere = "merge, sink", has 19 different meaning according to Oxford's English Dictionary. While emergence is also widely used in quantum statisti...
