Stephen Hawking is brilliant but unmotivated, Stephen Hawking was a 21-year-old PhD student at Cambridge when he first noticed something was wrong. He was falling down a lot, and dropping things. He went into the hospital for tests, and learned he had amyotrophic lateral sclerosis, or ALS. The doctors told him he would gradually lose control of every muscle in his body.
"My dreams at that time were rather disturbed," Hawking said. "Before my condition had been diagnosed, I had been very bored with life. There had not seemed to be anything worth doing. But shortly after I came out of hospital, I dreamt that I was going to be executed. I suddenly realized that there were a lot of worthwhile things I could do if I were reprieved."
The doctors gave the young man two and a half years to live. That was in early 1963. Over the next half century, Hawking defied all odds and went on to become one of the most celebrated scientists of the era, making major contributions to quantum cosmology and the understanding of black holes. Along the way, the wheelchair-bound Hawking became a cultural icon, a symbol of disembodied intellect and indomitable spirit.
