Dear all,
what are the differences between Caroll´s GR published book and the PDF text?
Thanks,

One big difference is that Chapter 9 from the published book, Quantum Field Theory in Curved Spacetime, is not included at all in the pdf version. This chapter is a nice introduction to the topic.

From Sean Carroll's webpages,

"About 50% of the book is completely new; I've also polished and improved many of the explanations, and made the organization more flexible and user-friendly."

There are several key differences between a printed book and a PDF text. First, a printed book is a physical object that can be held and read without the need for electronic devices, whereas a PDF text requires a device such as a computer or e-reader to be read. Additionally, a printed book can be easily shared and passed on to others, while a PDF text may have restrictions on sharing and distribution.

In terms of content, a printed book may have more visual elements such as illustrations or diagrams, while a PDF text may have limited or lower quality visuals. A printed book also allows for easier navigation and bookmarking, while a PDF text may require scrolling or searching for specific sections.

From a scientific standpoint, a printed book may have more credibility as it has undergone a rigorous publishing process and has been physically printed and distributed. A PDF text, on the other hand, may not have gone through the same level of peer review and may have a higher risk of containing errors or inaccuracies.

Overall, both printed books and PDF texts have their own advantages and disadvantages, and the choice between the two may depend on personal preference and the specific needs of the reader.
