Alan Cook facts for kids

Sir Alan Hugh Cook was a brilliant English scientist. He was a physicist, which means he studied how the world works. He was especially good at measuring things very, very precisely. His work helped us understand geophysics (the Earth's physical processes) and astrophysics (space and stars).

Early Life

Alan Cook was born in Felsted, England, in 1922. He was the oldest of six children. His father worked for customs and excise. His family went to church often, and Alan kept his Christian faith throughout his life. He went to school in Felsted and then at Westcliff High School. In 1939, he won a special scholarship. This allowed him to go to Corpus Christi College, Cambridge, a famous university. In 1948, he married Isabell Weir Adamson. They had a son and a daughter. Alan Cook passed away in 2004 from cancer.

Scientific Career

Alan Cook started studying science at Cambridge University in 1940. He learned about physical sciences, biological sciences, and geology. After graduating in 1943, he worked for the Navy during World War II. He helped with electronic counter-measures. After the war, he returned to Cambridge. He earned his doctorate degree by studying gravity in the British Isles. This work made him very interested in making super-accurate measurements in many areas of science. Later, he joined the National Physical Laboratory. There, he did many important experiments.

• He measured the exact density of mercury. This helped scientists figure out atmospheric pressure more precisely.
• He measured how fast things fall.
• He used the orbits of Sputnik satellites to understand Earth's gravity.

He also worked on improving how we measure time and length. He used advanced techniques like laser interferometry and masers. In 1966, he became a leader in the Laboratory's quantum metrology division. In 1969, he became a professor at Edinburgh University. He started the geophysics department there. Three years later, he moved back to Cambridge University. He became the Jacksonian Professor of Natural Philosophy at the Cavendish Laboratory. At the Cavendish Laboratory, he started a group that studied astrophysics. He did experiments with microwaves and tested gravity at very short distances. From 1979, he led the Cavendish Laboratory. One of his students was Michael Foale, who later became an astronaut! After he retired, Alan Cook became very interested in the history of science. He edited a journal about it for the Royal Society.

Honours and Awards

Sir Alan Cook received many important awards for his scientific work:

• 1969: He became a Fellow of the Royal Society. This is a very high honour for scientists.
• 1988: He became the President of the Royal Astronomical Society.
• 1988: He was given a knighthood, so he became Sir Alan Cook.
• 1993: He received The Chree Medal and Prize.
