I’m happy to announce the No Bullshit Guide to Math & Physics version 5.4 has been released. This update contains two years’ worth of text improvements based on readers’ feedback and suggestions. The main focus of the edits was the math fundamentals chapter, making it easier to follow for beginners. The other big news is that the book is now available in .epub and .mobi formats.
Below I’ll give an overview of the changes to the book with additional comments about the importance of each change. I’ve included links to PDF excerpts of all the new sections[1,2,3,4,5,6] as well as a detailed red-blue diff that shows all edits so this blog post can serve as a complete “patch” for readers who have an older version of the book.
