Andrew Engel was puzzled. He was sitting in class, but had no idea what the other students were talking about. He had done his homework, paid attention to lectures, and taken notes, but nothing was familiar. “Everyone is so much cleverer than I am,” he thought. It was a strange feeling, as he was always a good student in high school.
He felt even more puzzled a few days later. He got lost on his way to his favorite cinema. What’s worse, he began having trouble finding the right words when speaking. He asked, “What’s for dinner, Mom?” after he had just eaten. Poor Andrew, he was only 15!
His parents were worried and took Andrew to see a doctor. A brain scan（扫描） made it clear: Andrew had a malignant brain tumor(恶性脑肿瘤) . It was pressing on the part of the brain that makes new memory. He should be operated on as soon as possible. Andrew was scared!
Doctors removed the tumor, but Andrew’s memory was still poor. He was told he would probably never go back to school. Andrew was eager to enter a university, but it seemed that his dream wouldn’t come true.
“Even though they told me this, I knew I wanted to go back to school,” Andrew said. “I wanted to get my memory back.”
Andrew began by auditing(旁听) an English class at a nearby school. In class, he took notes carefully and read his notes several times a day, then typed them again and again. He studied twelve hours a day, seven days a week. He worked ten times harder than other students. In 2007, at age 29, he graduated from a local university. Six months later, Andrew found a job.

上是光子流，当光子流受到物体阻挡时，光子就撞到该物体上，就像空气分子撞到物体上一样，它
的动能就转化成对物体的压力。
大约100毫牛的力，用它推动100千克的物体，可产生1毫米/平方秒的加速度。这个加速度极其微小，只有地面重力加速度的一万分之一。
