Proszę przetłumaczyć,tylko nie z tłumacza !!!!!.Every so often, a genius comes along. Albert Einstein completely changed our ideas of space and time. He is called the "father of modern physics". But what does a genius look like as a child? Einstein was born in Germany. He wasn't impressive as a child. He was very slow to talk and his parents were worried about him. At school. his teachers weren't impressed, either. He found school boring and was badly-behaven! He left at the age of 15 without passing his final exams. 2.However, Einstein was very curious about the world. His father and uncle had an engineering company, and he was always asking questions about electricity and machines. When he was small, his father gace him a compass. Einstein was fascinated because the needle always pointed north. He wanted to fine out about the universe, but these things weren't taught in schools. So he read lots of books on his own. 3.Einstein finally finished his education in Switzerland. he wanted to work in a university, but no-one thought he was good enough. When he was 23, he got a job in a government office in Switzerland. His job was to look at people's inventions and give them a patent for their ideas. The work was easy for him and he had time to think. He spent a lot of time writing about the laws of physics and the universe. He sent his papers to scientific magazines. The science world was amazed to read them. No-one had ever heard of this young office worker. 4.Between 1901 and 1954, Einstein published more than 300 scientific works. When he was 30, he was finally offered a job at Zurich University. E =mc2 is his famous theory about energy. The idea was so advanced taht no-one could actually prove it worked until much later. In 1919, one of Einstein's theories about light was proved to be correct and he finally became famous. in 1921, he won the Nobel Prize of Physcics. he was very happy about this. But he told everybody, 'I have no special talents. i am only passionately curious.'
