A Briefer History of Time is a science humor book by the American astronomer Eric Schulman. In this book, Schulman presents humorous summaries of what he claims are the fifty-three most important events since the beginning of time.The title and cover are a parody of Stephen Hawking's book A Brief History of Time. Coincidentally, Hawking would later write a "sequel" entitled A Briefer History of Time. Hawking's publisher Bantam Books was aware the title had already been used in a popular science book, but went ahead since "The other book was published six years ago, and Professor Hawking is an international figure."
