Jason strives for realism in physics in science fiction. He spends a great deal of time looking at military studies of the limits of human G tolerance and how people can actually survive reentry. He tries very hard to have no ‘magic tech’ like inertia dampening and artificial gravity in his work. In this talk we’ll discuss why ‘magic tech’ is okay to use, when it’s too much, and why writers who stick to real physics can still produce incredibly dramatic scenes.
