I’ve watched Jurassic Park twice in my life – once when I was six and the second time a couple of weeks ago. It inspired me to think about how gaps in time change our way of perceiving.
Very little in science fiction can transcend the gimmickry of a technical conceit, yet without that conceit at its heart a book is not truly science fiction.
