Bye I'm so mad, are all texts on spherical geometry so hard to parse? It's not even difficult mathematically, I just can't imagine this was made for self studying. It probably wasn't, but how great is a book that is impossible to follow without a teacher. My entire experience reading this book is to use other sources to understand the book instead of the book being the main source I learn from, if I only needed a list of contents I could've gotten that from anywhere. Sigh.
