  2. 2. About Stephen William Hawking Stephen Hawking, born in 1942, British theoretical physicist andmathematician whose main field of research has been the nature of space and time, including irregularities in space and time known as singularities. Hawking has also devoted much of his life to making his theories accessible to the public through lectures, books, and films.Hawking was born in Oxford, England, and he showed exceptional talent in mathematics and physics from an early age. He entered Oxford University in 1958 and became especially interested in thermodynamics(the study of the interaction of matter and energy), relativity theory, andquantum mechanics (see Quantum Theory). In 1961 he attended a summer course at the Royal Observatory that encouraged these interests. He completed his undergraduate courses in 1962 and received a bachelor’sdegree in physics. Hawking then enrolled as a research student in general relativity at the department of applied mathematics and theoretical physics at the University of Cambridge.Hawking earned his Ph.D. degree from Trinity College at the University of Cambridge in 1966. He stayed at the University of Cambridge, doingpost-doctoral research, until he became a professor of physics in 1977. Hebecame one of the youngest fellows of the Royal Society in 1974. In 1979 he was appointed Lucasian Professor of Mathematics at Cambridge. During his postgraduate program, Hawking was diagnosed as having Amyotrophic Lateral Sclerosis (ALS), a rare progressive disease that handicaps movement and speech. This disease makes it necessary for Hawking to carry out the long and complex mathematical calculations that his work requires in his head. He has been able to continue his
  3. 3. studies and to embark upon a distinguished and productive scientific career despite his illness.From its earliest stages, Hawking’s research has been concerned with theconcept of singularities—breakdowns in space and time where the classic laws of physics no longer apply. The combination of time and three- dimensional space is called space-time. The most familiar example of a singularity is a black hole, the final form of a collapsed star. Much of what scientists believe about space-time comes from the theory of relativity, which was developed in the early 20th century by German American physicist Albert Einstein. During the late 1960s Hawkingproved that if the general theory of relativity is correct, then a singularity must also have occurred at the big bang. The big bang is the explosion that marked the beginning of the universe and the birth of space-time itself.The properties of space-time, the beginning of the universe, and a unifiedtheory of physics are all fundamental research areas of science. Hawking has made, and continues to make, major contributions to the modernunderstanding of all these areas. He has also made his work accessible to the public through several books, including A Brief History of Time (1988) and Black Holes and Baby Universes and Other Essays (1993), which are suitable for a general audience. In 1992 American filmmaker Errol Morris helped make A Brief History of Time into a film about Hawking’s life and work.
