时光机器

The time machine tells us that the world is four-dimensional, and any entity must extend in four directions. It must have length, width, thickness and duration in time. The time traveler invented the time machine and used it to take me on an amazing journey through time, allowing me to see the great changes that have taken place on earth in 80,000 years. At that time, all mammals except humans were extinct, and there was a terrible phenomenon of cannibalism. Through reading this book, I understand the basic principle of the existence of matter, I know the existence of the entity should be objective. Moreover, the study of human beings is only a small part of the whole scientific field, and the vast majority of the field is not understood by human beings at present. The power of human beings is very small, so we should respect the nature. When I grow up, I also want to explore the uncharted territory of mankind, to learn more about the principles of time and space. Through reading this book, I also learned that in addition to bringing benefits to mankind, scientific progress may also bring disasters to mankind. The rational use of technology will make our lives better, but if we let the evil forces to use technology, human beings will only encounter, and ultimately self-destruction. Therefore, we should not just develop the natural sciences, but also develop the social sciences, so that the development of human nature and the development of science and technology in step.
