Density Matrix Theory and Applications Book

Great Epistemological Approach to Popular Science

Learning more about stars, black holes and dark matter is a great part of the fun in this book, but I don't think it's the most important lesson I take from it.
Its Epistemological approach, its theory of how we know and learn things, is fascinating. First of all, by insisting on the question "how do they know that?", feeding this scientific curiosity. It then lays down its scheme of three universes: the perceived, the detected and the theoretical and how they interact with each order while we explore the nature of the universe itself. By setting this scenario, it guides us on presenting the most intriguing phenomena of astronomy and cosmology while also explaining how the experiments were performed to verify theories or how new measurements set new theories forward.
I have a background in engineering which helped me comprehend the physics and little mathematical details covered by the authors, but I believe that any motivated layperson might enjoy the reading.
It satiated my curiosity about how dark matter and dark energy became a topic of studies but also gave me tools on how to deal with scientific communication of daily life.
