Tears of Joy
When Twitter Books asked its followers about the last book that made them cry, this is probably not the response they were expecting. We know university isn’t exactly easy so we understand why this person chose this Physics book as their answer.

What we bet they didn’t expect was that the author of the book, Roger Freedman would respond to the tweet and even be cheeky about it. He actually suggested that the commenter was referring to “tears of joy” no doubt, even though he knew full well that wasn’t the case. It looks like Freedman had the last laugh in this case.
