Input: Consider Input: The Theory of Everything: The Origin and Fate of the Univers . It has come to our attention that the book "The Theory of Everything: The Origin and Fate of the Universe" has been published. Professor Hawking would like to make it clear that he has not endorsed this book. The text was written by him many years ago, however the material has already been published in books such as 'A Brief History of Time'. A complaint was made to the Federal Trade Commission in the US in the hope that they would prevent the publication. We would urge you not to purchase this book in the belief that Professor Hawking was involved in its creation.

Output: NEG

Input: Consider Input: Preposterous! . This book begins with the absurd claim that 'the natural numbers -1, 2,3, 4 etc- appear to have been present at the birth of the universe; part and parcel of the original material from which was knit the ever-expanding continuum of space-time.' The author does not explain in whose mind these numbers are supposed to have appeared or how a concept can be present without a mind to concieve it. Like many mathematicians he seems unable to grasp that mathematics is a language. Thus it's not uncommon to hear ridiculous statements like 'the universe is governed by mathematics' As if numbers exert forces. But this is the first time I've encountered the claim that numbers existed prior to life!

Output: NEG

Input: Consider Input: Out of Ideas . Back in his day Heinlein was the greatest writer of science fiction for adolescent boys. Unfortunately, that day is long past, and Heinlein has wandered far from his strength. This book fills in some gaps from Time Enough for Love and is a rehash of much of that story from an alternate viewpoint. As was the case in Time Enough for Love, sexual coupling of old men and young girls is a recurring theme. Examples: The two female lead characters brag to one another how they had their first sexual experience at ages 12 and 14 and with men 4 times their age. The male lead goes back in time and has sex with his sister, then a young teen, and he, at this point, the oldest man in human history. To make all this go down easier, the young females are the sexual aggressors and the old men are pursued, and said to be 'tripped' if she has her way with him. There is a lot more of this 'weird sex', but I will move on. This is not really a science fiction story per se, but there are a few trappings of science fiction used to decorate the story. Most of it takes place in the first half of the 20th century in mid America. There isn't really a plot. The book is a series of anecdotes occuring in the life of this unlikely heroine, seemingly Heinlein's feminine ideal. It is obvious that the author has run out of ideas at this late point in his career. This book would not have been published if it was the work of an unknown author.
