1905 published three papers in the well-known professional journal "annual physics", offering suggestions and putting forward a brand-new theme: the special theory of relativity appeared an equation in later generations, and the author was a 26-year-old young man, Albert Einstein, an employee of Berne Patent Office. 15 years later, experiments confirmed this theory, astronomers confirmed the theory of relativity, and opened one of the greatest myths of the 20th century. The author traces the life course of a special character, whose life is only influenced by one maxim, that is, "the pleasure of thinking".
