  4. 4. Challenging life of Stephen Hawking • Stephen Hawking was born on 8 January 1942 to Frank and Isobel Hawking. Despite family financial constraints, both parents had attended the University of Oxford, where Frank had studied medicine and Isobel, Philosophy Politics and Economic. The two met shortly after the beginning of the Second World War at a medical research institute where Isobel was working as a secretary and Frank as a medical researchers.
  5. 5. Spreading of disease   In early 1963, just shy of 21, Hawking was diagnosed with motor neurone disease, more commonly known as Lou Gehrig's disease. He was not expected to live more than two years. Completing his doctorate did not appear likely. Yet Hawking defied the odds, not only attaining his Ph.D. but forging new roads into the understanding of the universe in the decades since. As the disease spread, Hawking became less mobile, and was confined to a wheelchair. Talking grew more challenging and, in 1985, an emergency tracheotomy caused his total loss of speech. A speech generating device constructed at Cambridge, combined with a software program, serves as his electronic voice today, allowing Hawking to select his words by moving the muscles in his cheek.
  6. 6.   Hawking continued at Cambridge after his graduation, serving as a research fellow, and later as a professional fellow. In 1974, he was inducted into the Royal Society, a worldwide fellowship of scientists. In 1979, he was appointed Lucasian Professor of Mathematics at Cambridge, the most famous academic chair in the world (the second holder was Sir Isaac Newton, also a member of the Royal Society. Over the course of his career, Hawking studied the basic laws governing the universe. He proposed that, since the universe boasts a beginning – the Big Bang – it will likely have an ending. Working with fellow cosmologist Roger Penrose, he demonstrated that Einstein's General Theory of Relativity suggested that space and time began at the birth of the universe, and ends within black holes, a result that implied that Einstein's theory of General Relativity and quantum theory must be united.
  7. 7.  Hawking is a popular writer. His first book,"A Brief History of Time," was published in 1988 and became an international best seller. In it, Hawking aimed to communicate questions about the birth and death of the universe to the lay person.  Since then, Hawking has gone on to write other nonfiction books aimed at nonscientists. These include "A Briefer History of Time," "The Universe in a Nutshell," "The Grand Design," and "On the Shoulders of Giants."
