Beyond The Galaxy: How Humanity Looked Beyond Our Milky Way And Discovered The Entire Universe by Ethan Siegel (PDF)

Description

A look up at the night sky reveals a treasury of wonders. Even to the naked eye, the Moon, stars, planets, the Milky Way and even a few star clusters and nebulae illuminate the heavens. For millennia, humans struggled to make sense of what’s out there in the Universe, from all we can see to that which lies beyond the limits of even our most powerful telescopes. Beyond the Galaxy traces our journey from an ancient, Earth-centered Universe all the way to our modern, 21st century understanding of the cosmos. Touching on not only what we know but also how we know it, Ethan Siegel takes us to the very frontiers of modern astrophysics and cosmology, from the birth of our Universe to its ultimate fate, and everything in between.

User’s Reviews

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐”This is not just the story of the Universe as we presently understand it, but also the story of how the scientific process works in general.”That’s why it must be the first page turner to contain meson diagrams.An excellent primer for beginning space nerds and wannabe astrophysicists of all professions, and a neat reference for the more advanced ones. The best part is that it shows the history and process of how science is made, including wrong assumptions and colorful personalities and simple rules to separate workable from useless theories. (“Can it make novel predictions that would be supported by experiments?”) It emphasizes scientific understanding as an evolving process instead of a holy writ – something I happen to find particularly appealing both about this book and about science as my own profession.In addition, the author succeeds in addressing lay audience in a colloquial style that still never doubts the intelligence or logic of the reader. Combine that with the sense of humor and the fact that every time I started thinking “this is confusing, let me draw it out” there was a neat diagram on the very next page… I want a sequel, thank you.

⭐A really fun romp through the history of astronomy that is fun to read, thanks to the author’s good writing skills, including some fascinating discussion of inflation and its implications. I thought the treatment of special and general relativity were extremely sparse, so you’ll have to pursue that elsewhere, But most other topics about the structure of the cosmos and its evolution over time are well explained. Tons of color graphics provided.Pretty recent, although printed in 2016, it doesn’t record the observation of gravitational waves in 2017.Definitely worth a read.

⭐We attended a lecture of his earlier in the month, and mid-lecture, we were on Amazon, purchasing a copy of this book. Highly recommend. This book would be terrific as an audio book, with him doing the voice work. He does a great job of approaching some pretty meaty topics in an engaging, approachable, and thorough way – and acknowledges that not everyone has a Ph.D. in this stuff, and doesn’t hold it against them, or lord it over them. Bravo!

⭐Well written in content and form, with very high scientific integrity — the best I have found. Highly recommended

⭐Very interesting journey through the ages on man’s concepts of the universe. Very interesting when discussing current concepts. Ties in current thinking on quantum mechanics, dark matter , dark energy etc. in a way that a non-astrophysicist (like me) can understand. NO MATH 🙂

⭐I have read many astrophysics for the common man, Cosmology without the math, but Ethan Siegel has written the most wonderful, informative book on Cosmology…with Just enough math brilliantly explained so that even I understood every word! IT really is an eye opening life changing book. I heartily recommend it,and I rarely if ever do that. There is nothing to fear…it’s good.

⭐Incredibly insightful and well written. Ethan Siegal is one of the best writers in the world who is writing about scientific subjects. The fact that he actually IS a scientist means you get accurate information, and that’s a hot commodity in science journalism today.

⭐A good updater on present cosmological thinking. I especially applaud his pointing out the weaknesses of current ideas; there is too little of this in modern science writing.

⭐I was considering myself being knowledgeable in the subjects approached by this book but I was so wrong ! I am glad I red it as so many things clarified. Style is simple and concise even when Ethan goes to relatively complex explanations.

⭐In the current description on Amazon it’s not clear, but even in the “paperback” edition (at least, 978-9814667166 I have) the whole book is printed full-color on the glossy paper, much higher quality than the typical plain paperback book. The letters are big and easy to read. The book has 388 pages, not 300 like the description on Amazon.de claims, and that’s good, because that’s the number of pages in the hardcover version, so nothing is reduced. I’ll comment on the content after I read the book. Potential buyers can sample author’s style and approach in many of his articles on the web.

⭐It’s a amazing Book, I truly recomend. I saw many things that I even though to be true. Please, read this book if you realy want to know a bit more about the nature of our universe.

⭐The Introduction states that the book is aimed to be an “introductory course” in Astronomy; “there are no problems to be solved or worked out, no formulas and no equations….and any mathematical or physical relationships …are described in plain English”. So we get Kepler’s Law explained as “They all orbited with period related to their semi-major axes in proportion to the 3/2 power”. Mmm?The books starts reasonably well explaining the historical discoveries but in the later chapters gets far too bogged down in the details of atomic particle physics. I would challenge a Physics Grad to explain in simple English what fig 9.10 means. Baryon Density? What’s that all about, and why is it in an Astronomy primer book?Many of the photographs and diagrams have been lifted (with acknowledgements) from other publications or the internet. The trouble is they are all printed up in low-resolution and look tatty.This book is neither an introductory course or a textbook for the serious graduate student. I cannot recommend it.

⭐Ethan`s book was exceptionally entertaining and informative. I like his use of illustrations. Great book, Ethan.
