Today (July 08, 1695) is the birthday of Christiaan Huygens, who took part in the world scientific revolution through the wave principle that light propagates in waves.

Today (July 08, 1695) is the birthday of Christiaan Huygens, who took part in the world scientific revolution through the wave principle that light propagates in waves.

Christiaan Huygens was born on April 14, 1629 in Den Haag, Netherlands. Studied law, and mathematics at Leiden University. After that, he started studying science. Huygens discovered the lens of the telescope. He studied the sky with it. It was designed by Huygens, a simple eyepiece used in low-cost telescopes today. He attracted worldwide attention due to his wave theory that light propagates in waves. Huygens' theory later helped to explain the wave-particle duality that light has the duality of particle and wave. Huygens' famous discovery was that "every point of a wave interface can be considered as the starting point of the second wave of waves. This is called Huygens philosophy.

In 1655 he discovered Titan, the largest satellite of Saturn. Larger than Mercury, it is the largest satellite in the Solar System. The previous largest satellite was Jupiter's "Conimet". In 1656 he also explored the rings of Saturn and discovered that they were made of small rocks. Huygens, who discovered Titan, is named for the astronomical landing vessel on Titan sent by NASA in the United States. The spacecraft was sent to study Titan, which has a dense atmosphere similar to that of the Earth's atmosphere millions of years ago.

In 1659, Huygens explored the Orion nebula and drew a model of it. His painting is the first map of the Orion volume. Through his television, Orion separated the different parts of the atmosphere and gave clear explanations of it as early as the 17th century. In honor of this work, the luminous center of the Orion cluster was named the "Hygiene Area" in his memory. Huygens also invented the pendulum clock to help determine time. He discovered that even if he operated only one of the two pendulums, which could be built on a single source of flexibility, the movement would be carried to the next pendulum and the same vibration and counter-vibration would occur alternately. This pendulum swing is still found in science centers today.

He also rewrote Isaac Newton's second law of motion into a quadratic equation. At the request of Eloise Pascal, he wrote a book on the theory of probability and published it in 1657. His contribution to the development of contemporary computational and differential calculus is considered important. Christiaan Huygens, who took part in the World Scientific Revolution through wave theory, passed away on July 08, 1695, at the age of 66, in The Hague, Dutch.
