It is well known that Albert Einstein was one of the greatest scientists of all time and he was also a really great person. Here are some interesting things about him. When Einstein started to work in America, someone asked him what he needed. He said he needed a desk, some paper and a pencil. He also asked for a big waste-paper basket to hold all of his mistakes. This shows that he knew even the cleverest man in the world can only learn by making mistakes. Einstein regarded time as very important. He never wore socks and he thought putting on socks was a waste of time as people already wore shoes. He also thought it was a waste of time remembering things that could quickly be found in a book. That's why he never remembered his own phone number, which was in the phone book. He knew what was worth remembering. It is true that if we are going to do great things in our lives, we can not waste our time. Einstein liked to joke too. Once in an exam a student asked him why all the questions were the same as last year's. Einstein replied the questions were the same but the answers were different! ,A, B, C, D,,. In one exam, Einstein   _  .
