The colour pdf tells about animals and sport (mechanics and heat), about the sky at night (relativity and the structure of the universe), about lightning, nerves and the brain (electricity, light, language and truth), and about colours, pleasure and the stars (basic and advanced quantum physics). The text provides as many interesting facts as possible, together with their general description. It aims to make one enjoy looking at nature, thinking about nature, and experimenting with nature. If you are interested, a separate research volume tells about the search for a final, unified theory of physics.
