A gunpowder engine, also known as an explosion engine or Huygens' engine, is a type of internal combustion engine using gunpowder as its fuel. The concept was first explored during the 1600s, most notably by famous Dutch polymath Christiaan Huygens .
Christiaan Huygens, Lord of Zeelhem, FRS (/ ˈ h aɪ ɡ ən z / HY-gənz, [2] US also / ˈ h ɔɪ ɡ ən z / HOY-gənz; [3] Dutch: [ˈkrɪstijaːn ˈɦœyɣə(n)s] ⓘ; also spelled Huyghens; Latin: Hugenius; 14 April 1629 – 8 July 1695) was a Dutch mathematician, physicist, engineer, astronomer, and inventor who is regarded as a key figure in the Scientific Revolution.
Invention of the pendulum clock by Christiaan Huygens by Georg Sturm (c. 1885). The motivation behind Horologium Oscillatorium (1673) goes back to the idea of using a pendulum to keep time, which had already been proposed by people engaged in astronomical observations such as Galileo. [4]
Christiaan Huygens was the first person to describe Saturn's rings as a disk surrounding Saturn. In 1655, Huygens became the first person to suggest that Saturn was surrounded by a ring, after Galileo's much less advanced telescope had failed to show rings. Galileo had reported the anomaly as possibly 3 planets instead of one.
From its invention in 1656 by Christiaan Huygens, inspired by Galileo Galilei, until the 1930s, the pendulum clock was the world's most precise timekeeper, accounting for its widespread use. [ 1 ] [ 2 ] Throughout the 18th and 19th centuries, pendulum clocks in homes, factories, offices, and railroad stations served as primary time standards ...
The invention resulted in a great advance in the accuracy of the mechanical watch, from around half an hour to within a few minutes per day. [178] Some dispute remains as to whether the balance spring was first invented by Huygens or by Hooke; both scientists claimed to have come up with the idea of the balance spring first.
Huygens claimed an accuracy of 10 seconds per day. In a pendulum clock, the verge escapement is turned 90 degrees so that the crown wheel faces up (top). The verge escapement consists of a wheel shaped like a crown, called the escape wheel, with sawtooth-shaped teeth protruding axially toward the front, and with its axis oriented horizontally.
1690 – Christiaan Huygens gives the first estimate of the speed of light in air or vacuum, based on Rømer’s work. The result is equivalent to about 2×10 8 m/s in modern units, correct only to the order of magnitude.
