Lectures on Astrophysics provides an account of classic and contemporary aspects of astrophysics, with an emphasis on analytic calculations and physical understanding. It introduces fundamental topics in astrophysics, including the properties of single and binary stars, the phenomena associated with interstellar matter, and the structure of galaxies. Nobel Laureate Steven Weinberg combines exceptional physical insight with his gift for clear exposition to cover exciting recent developments and new results. Emphasizing theoretical results, and explaining their derivation and application, this book provides an invaluable resource for physics and astronomy students and researchers.

In Memoriam: Steven Weinberg (May 3, 1933 – July 23, 2021).
This is a sad occasion, writing this book review one week after the passing of physicist Steven Weinberg. Having been a lifelong student and admirer of Weinberg, there was no way I was going to ignore his book of lectures on astrophysics. It is dense. It is terse. It is challenging. However, Weinberg does not promise anything that he can not deliver. As is his custom, Weinberg stresses the interplay between theory and experiment, how to arrive at numbers. Interestingly, dimensional analysis is used in various circumstances (pages 42-49). You get a derivation of relativistic equilibrium condition (page 68, also, you are referred to his 1972 tome on General Relativity for alternative derivation). Tools of the trade include the oft-utilized method of "integration-by-parts" and the oft-utilized "power series expansion." I enjoy section #2.1: "how observations are used to find the properties of binary stars." (page 83). You derive inequalities (examples: tidal distortion, page 87, maximum luminosity, page 149 and Schwarz inequality, page 190). You will get a review of gravitational radiation in preparation for a discussion of LIGO (pages 98-104). There is a discussion of HII regions (ionized Hydrogen surrounding stars): it is insightful, lucid and easy to follow (see section #3.2). You will learn something new as you consider effects of viscosity in gas rotating around an axis of symmetry (pages 150-153). A discussion of Galaxies concludes the lectures, recall the Boltzmann equation and Euler equations of hydrodynamics, while learning that "the formalism presented above allows the construction of equilibrium distribution functions for galaxies in clusters and for dark matter." (page 178). A motivation to peruse this book, according to Weinberg, is the opportunity to bring his earlier book up-to-date (1972, Gravitation and Cosmology). Because my personal library holds many of Steven Weinberg's bibliographic references, the lectures were easier to assimilate than they might otherwise have been. There is more here to learn and I intend to learn it: if for no other reason than to pay homage to a brilliant physicist, a fine teacher and a fine human being. He will surely be missed.

O livro é uma “pincelada” num assunto tão vasto. O autor não precisa de mais apresentação; Weinberg, ganhador de Prêmio Nobel. Ótimo livro.

Not for plebs who want a casual read but are able to engage the material in a technical way. Not like his First Three Minutes but as the book says these are lectures in the best of tradition, think Chandrasekhar, Eddington, Peebles, etc. Very mathematical but the physics is not lost in the masterly crispness of exposition. I found that reading his semi-popular works immensely helps in reading some of the more technical works.
Update - It's sad to have lost Steven Weinberg. It feels personal somehow. He was from a generation that sported greats like Feynman, Wheeler, Schwinger, and all the others from the post-war generation. As a Physicist, only a great physicist may comment on his greatness but I do think that he was a great man based on his scientific writings for the public. Richard Dawkins rightly called him 'A real public intellectual in an era where the term intellectual is bandied about'. For me reading his book The First Three Minutes was an eye opener of how great physicists think but also helps convey deep and unintuitive knowledge in a way that's not jargon driven but hits the mark every time. Never one to talk down to his audience, his books are a friend holding your hand. Where he is technical, he implicitly considers you to be fluent in mathematics to follow the scientific argument.
To 'Explain the world' will seal Weinberg as not only a physicist of great measure but equally in his immense writing skills to comment on its historical evolution. That's rare. Physics or its History is usually the preserve of specialists in one field or the other but not both as a Physicist and Historian of Science. As a historian, he's in the class of Pais who was like him both but I feel Steven Weinberg was clearly the greater physicist (based on his unification work) and given his breadth and depth of span in this field. I mean the list is like everything!! Particle, Relativity, Cosmology, QM, QFT, Semi-Technical writing. The man was a monster mind in the class of the front-line physicists like Heisenberg, Einstein, Eddington, or Schrodinger
