Stephen Hawking

Stephen William Hawking was born on January 8, 1942, in Oxford, England, during the height of the Second World War. His parents, Frank and Isobel Hawking, had moved from London to Oxford to seek a safer environment for the birth of their first child. Hawking grew up in a highly intellectual household where education was deeply valued. In 1959, at the age of seventeen, he entered University College, Oxford, to study physics and chemistry, finding the academic work exceptionally easy. After graduating with a first-class honors degree in natural science, he transitioned to Trinity Hall, Cambridge, in 1962 to pursue graduate studies in cosmology under the supervision of Dennis Sciama. It was during his early years at Cambridge that Hawking began experiencing symptoms of physical clumsiness, which led to a diagnosis of amyotrophic lateral sclerosis (ALS), a form of motor neurone disease, in 1963. Doctors initially gave him only two years to live. Although the diagnosis plunged him into a brief depression, it ultimately galvanized his academic focus, spurred on by his relationship with Jane Wilde, whom he married in 1965.\n\nHawking's early scientific breakthrough came in the late 1960s through his collaboration with the mathematician Roger Penrose. Applying the mathematics of general relativity to the entire universe, Hawking and Penrose demonstrated that if the universe obeys general relativity and contains the matter we observe, it must have begun as a singularity—a point of infinite density and spacetime curvature. This work, published in 1970, provided a robust mathematical foundation for the Big Bang theory, showing that time and space indeed had a physical beginning.\n\nIn the early 1970s, Hawking turned his attention to the physics of black holes. In 1974, he published a revolutionary paper in the journal Nature titled 'Black hole explosions?', which shocked the physics community. Utilizing quantum field theory in a curved spacetime background, Hawking calculated that black holes are not completely black. Instead, quantum fluctuations near the event horizon allow virtual particle-antiparticle pairs to form; one particle falls into the black hole while the other escapes as thermal radiation. This phenomenon, subsequently named Hawking radiation, implied that black holes lose mass over time and will eventually evaporate entirely. This discovery bridged thermodynamics, quantum mechanics, and general relativity, but it also introduced the 'black hole information paradox'—the unresolved question of what happens to the physical information encoded in matter that falls into a black hole once the black hole evaporates.\n\nHawking continued to push the boundaries of theoretical cosmology in the 1980s. Alongside physicist James Hartle, he proposed the Hartle-Hawking state in 1983, often referred to as the 'no-boundary proposal.' This model suggested that before the Planck epoch, the universe had no boundary in space or time; instead, time behaved like a spatial dimension, effectively removing the need for a singular beginning point in the traditional sense. In 1979, Hawking was appointed the Lucasian Professor of Mathematics at Cambridge, a prestigious chair once held by Isaac Newton. He held this post for thirty years until his retirement in 2009.\n\nBeyond his academic achievements, Hawking became a global cultural phenomenon through his efforts to popularize science. In 1988, he published 'A Brief History of Time: From the Big Bang to Black Holes'. Written in non-technical language, the book explained complex topics such as cosmology, superstring theory, and the unification of physics. It became an unprecedented commercial success, spending more than four years on the Sunday Times bestseller list and selling millions of copies worldwide. Despite his severe physical limitations—by the late 1980s, he had lost his voice following a tracheostomy and relied on a computerized speech-generating device operated by his cheek muscle—Hawking traveled extensively, giving public lectures and advocating for scientific literacy and disability rights.\n\nThroughout his later life, Hawking received numerous accolades, including the Albert Einstein Award, the Hughes Medal, the Copley Medal, and the Presidential Medal of Freedom, the highest civilian honor in the United States. He was elected a Fellow of the Royal Society in 1974, one of its youngest members. While he never received the Nobel Prize in Physics—largely because Hawking radiation remains extremely difficult to observe experimentally—his theoretical insights fundamentally reshaped modern physics. Hawking passed away on March 14, 2018, at his home in Cambridge at the age of seventy-six. His ashes were interred in Westminster Abbey, positioned between the graves of Isaac Newton and Charles Darwin, a fitting tribute to his monumental legacy in the history of science.
