The Time Machine is the first book on the subject of time travel. In the first chapter, it first describes the manner and environment of the time traveler to talk about profound problems, then from the mathematician's view that space only has three dimensions to four-dimensional geometry, and then begins to discuss whether time is the fourth dimension of space. The time traveler says that it is wrong to be unable to move in time, such as memory. He said he was thinking of a machine to travel through time, and then it's written in the book that he had a little model machine, and then he took the doctor and Philby and they showed them a real time machine, and he said he wanted to explore time.
