“Welcome To The Universe” is an introductory text to astrophysics and cosmology for the undergraduate student who isn’t learning a science major, or for the well educated adult whose interest in astronomy has gotten further from the usual popular science books that steer clear of formulas and equations.

This book is about some of the ideas in astrophysics and cosmology that are necessary for getting a further understanding of the fields without taking a full mathematical astrophysics or cosmology course.

As such I think it really is perfect book for the intended reader – it doesn’t offend the reader by assuming that equations would go just over their heads, but it also doesn’t get too deeply into them to be of much use for an astronomy major.

The book is quite enjoyable, well illustrated and covers some fascinating topics for an introductory astronomy course. I wish everyone would read this book – you don’t get too much technical details, but just the bare essentials. If you want to find out more – find another book,but this will certainly whet your appetite.

The book has been written so, that you can tell who wrote which chapter, but despite having three authors in makes a complete, an fluid book – you might not even notice that there are three authors, except for when their achievements or work is mentioned specifically.

I got this book right at the beginning of a vacation and I hoped to finish reading it in two weeks, one of which I spent travelling. My book is quite a massive hardcover edition, but I was motivated enough to carry it with me for about three weeks. It was worth it – it was great travel reading in the sense that the beginning chapters are quite simple. However a few chapters in I did start to wonder whether there would even be any new for me information in the book. For a while there wasn’t any. Then there were tiny examples of what was to come – by the end of the book there were fascinating chapters that presented information that I hadn’t read before.

It’s a great book. My rating of 8/10 comes from me not being really one of the intended audience and that I got mildly bored at the beginning of the book (boredom went away by about the middle). It really deserves 10/10.

Book 220: The Cosmic Web by J. Richard Gott


The Cosmic Web by J. Richard Gott

Rating: 9/10

“The Cosmic Web” is about the largest structures in the Universe, how it was discovered, who were behind it, what were some other competing ideas and how we see it all now.

In this book Gott tells the story of his and some other cosmologists’ part in discovering the structure of the universe that could be called a cosmic web, but has at other times been referred to as a cell-like structure etc.

In the book you can learn more about what were the early ideas of how the great structures in the Universe might look like, and what would be necessary for their formation, and we see that from two perspectives – from the US school, where the so-called meatball theory prevailed and also from the Soviet school where the ideas took more of a pancake shape that all lead to more of a Swiss cheese type of structure.

The book gives a lot of details and background information about the structure’s discovery and what led to it with a few detours to Gott’s own life in science, which makes for nice pauses between the more mathematical parts of the book.

As a book on a specific topic in cosmology, it’s interesting and illuminating, but definitely not an easy read, but you do go over some of the cosmic microwave background surveys, the accelerating¬†inflation of the¬†universe and the inflation theory and the possible end of the Universe as well, so you see the context of the main theme better.

It was really a great book, just it requires a bit of effort from the part of the reader.
