Titan Explanation of Saturn's rings Centrifugal force Collision formulae Pendulum clock Huygens–Fresnel principle Wave theory Huygens' engine Birefringence Evolute Huygenian eyepiece 31 equal temperament musical tuning Huygens–Steiner theorem; 14 April 1629 – 8 July 1695) was a Dutch physicist, mathematician, astronomer and inventor, who is widely regarded as one of the greatest scientists of all time and a major figure in the scientific revolution.
Huygens speculated that extraterrestrial life was possible on planets similar to Earth and wrote that the availability of water in liquid form was a necessity for life.
Huygens was educated at home until turning sixteen years old.
In addition to inventing it, Huygens continued his research on pendulums and wrote in 1673 an extensive analysis of the pendulum in his book Horologium Oscillatorium, a major work on pendulums and horology, which is regarded as one of the three most important works done in mechanics in the 17th century.
While the first part of the book contains a description of clock designs, the most part of the book is an extensive analysis of pendulum motion and a theory of curves.
In political terms, the First Stadtholderless Period that began in 1650 meant that the House of Orange was not in power, removing Constantijn's influence.
Further, he realised that his son had no interest in such a career.
The modern concept of probability grew out of the use of expectation values by Huygens and Blaise Pascal (who encouraged him to write the work).
The last years of Huygens, who never married, were characterized by loneliness and depression.
His most famous invention, however, was the invention of the pendulum clock in 1656, which was a breakthrough in timekeeping and became the most accurate timekeeper for almost 400 years In 1659, Huygens was the first to derive the now standard formula for the centripetal force in his work De vi centrifuga, a formula that was published in 1673 in the Horologium Oscillatorium, his book on pendulums.
The formula played a central role in classical mechanics and became known as the second of Newton's laws of motion.
