science fiction novels
I have read a number of the previous posts. Many authors are having individuals read their manuscripts and then these individuals offer their feedback to the author. I have a counter intuitive notion that I believe applies to science fiction novels and perhaps other genres, as well. I believe the reading audience (through the influence of the publishing houses) has become accustomed to grammatically flawless novels, but also in the field of science fiction especially, the audience has become accustomed to novels that are full of scientific and mathematical errors. I have never heard or read about any author or other experienced professional giving this advice to writers, but I believe to fulfill the expectations of the reading audience a science fiction novel must have very many scientific and mathematical errors in it. These errors can be both small and large. I would suspect that helpful readers would suggest to the author that he remove scientific errors from a work in progress but that may not be the best course of action.
