John Stewart Bell (born June 28, 1928 – died October 1, 1990) was a brilliant physicist from Northern Ireland. He was a member of the Royal Society. He is famous for creating something called Bell's theorem. This theorem is a very important idea in quantum physics, which studies the tiny particles that make up everything. It helped us understand more about how these tiny particles behave.
Early Life and His Work
John Bell was born in Belfast, Northern Ireland. When he was 11 years old, he decided he wanted to be a scientist. By the age of 16, he had already finished high school.
He then went to the Queen's University of Belfast. In 1948, he earned a degree in experimental physics. A year later, he got another degree in mathematical physics. He continued his studies at the University of Birmingham. In 1956, he earned his Ph.D. in physics. He focused on nuclear physics and quantum field theory.
In 1954, John married Mary Ross, who was also a physicist. They met while working on accelerators in the UK.
Bell started his career at the UK Atomic Energy Research Establishment. This place is also known as Harwell Laboratory. After several years, he moved to Geneva, Switzerland. There, he worked for the European Organization for Nuclear Research, known as CERN. At CERN, he mostly worked on theoretical particle physics. He also helped design particle accelerators. Even with all this work, he found time for his main passion. He loved to explore the basic ideas of quantum theory.
His Legacy and Impact
John Bell sadly passed away in Geneva in 1990. He died from a brain hemorrhage. Many people believe he was nominated for a Nobel Prize that year. He did not know about the nomination.
- In 2008, a special award was created in his honor. It is called the John Stewart Bell Prize. The University of Toronto gives this award. It celebrates big discoveries in quantum mechanics. It also recognizes new ways to use these principles.
- There is a street named Route Bell at the CERN site in Meyrin. This street is near Geneva. It was named to honor John Stewart Bell.
- A special day was named after him: November 4. This date is when he shared Bell's theorem with the world.
- Since 2015, there is also a street in Belfast named Bell's Theorem Crescent. This is his hometown.
- The John Bell House was built in 2016. It is in Belfast city center. This building houses over 400 students.
- The entrance to the Olympia leisure center in Belfast is named after him. It is called the "John Stewart Bell Entrance." This center is very close to where he grew up.
- At the Queen's University of Belfast, one of the physics lecture halls is named after John Stewart Bell.
