Stephen Hawking, scientist: “Quiet and silent people are the ones who have the strongest and loudest minds”
The English physicist was diagnosed with ALS at age 21 and managed to live 55 years longer than science predicted.

Stephen William Hawking was a British theoretical physicist and cosmologist. Born on January 8, 1942 in Oxford, Hawking is considered one of the most influential scientists of the second half of the 20th century due to his contributions to fundamental physics and cosmology.
Hawking completed his undergraduate studies at University College, Oxford, where he earned a degree in physics, and continued his postgraduate education at Trinity Hall, Cambridge, specializing in general relativity and cosmology. It was at Cambridge that he spent most of his academic career, eventually becoming the Lucasian Professor of Mathematics, one of the most prestigious positions in the scientific world, which he held from 1979 to 2009.
Hawking’s illness did not halt passion for science
From the age of 21, Hawking lived with amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease that gradually left him almost completely paralyzed and dependent on a voice synthesizer to communicate. Despite these physical limitations, he continued researching and teaching for decades, defying medical expectations and becoming a symbol of intellectual perseverance.
Although Hawking is universally recognized for his work in theoretical physics, he was also a thinker who reflected deeply on the mind, creativity, and the value of introspection. The phrase, “Quiet people have the loudest, strongest minds,” reflects his relationship with his own physical condition. As his body weakened, his mind grew stronger. He lived more than 50 years longer than doctors originally predicted.
Hawking’s biggest contributions
In the scientific field, Hawking made decisive contributions to the understanding of black holes and the structure of the universe. In 1974, he proposed that black holes emit radiation, now known as Hawking radiation, combining principles of quantum mechanics with general relativity. This theory revolutionized the way scientists understood these cosmic objects and opened new paths in modern physics.
Beyond academic research, Hawking became one of the most important scientific communicators of his time. His book A Brief History of Time: From the Big Bang to Black Holes (1988) became an international bestseller, translated into dozens of languages and bringing complex concepts of cosmology to millions of readers around the world.

Throughout his career, he received numerous honors, including becoming a Fellow of the Royal Society, earning the Copley Medal, and receiving the Presidential Medal of Freedom in 2009, one of the highest civilian distinctions in the United States. He also left a mark on popular culture. He appeared in television series such as The Simpsons and Star Trek: The Next Generation, and his life story was portrayed in the film The Theory of Everything (2014).
His scientific legacy, along with his extraordinary ability to connect complex ideas with the general public, continues to inspire researchers, students, and science enthusiasts worldwide.
