Instead of you, take apart objects and technological devices in daily life and have a glimpse of the operating principle behind them!
● scientific principles ranging from eraser to rocket launch.
● clear and detailed sectional drawings and perspective drawings, and explain the internal structure and operation mode of the object step by step.
● take you to explore how scientists are inspired by devices in science fiction and realize it step by step in the real world.
● the explanation of the principle is simple, the pictures are vivid, and the little experiment is more interesting. Let the children do it together.
● true stories from the laboratory, understanding the invention and research process of scientists and engineers, and their biographies.
Have you ever wondered how the microwave oven heats food? Do you want to open the computer and see what's hidden inside? Did you know that the invisibility cloak exists not only in the story of Harry Potter, but also in the real world?
