Description: (Mathematician)
Alexis Claude Clairaut was a prominent French mathematician, astronomer, and geophysicist recognized for his significant contributions to the validation of Sir Isaac Newton's theories. He played a key role in verifying Newton's theory on the Earth's figure during an expedition to Lapland. Clairaut is credited with formulating "Clairaut's theorem" and making important advancements in the gravitational three-body problem, particularly in the apsidal precession of the Moon's orbit. Additionally, his work encompasses Clairaut's equation and Clairaut's relation in mathematics.
