Pressure in water and air. Pascal's law applies for fluids. Pascal's principle is defined as: A change in pressure at any point in an enclosed incompressible fluid at rest is transmitted equally and undiminished to all points in all directions throughout the fluid, and the force due to the pressure acts at right angles to the enclosing walls.
1621 – Willebrord Snellius: Snell's law; 1632 – Galileo Galilei: The Galilean principle (the laws of motion are the same in all inertial frames) 1660 – Blaise Pascal: Pascal's law; 1660 – Robert Hooke: Hooke's law; 1662 – Robert Boyle: Boyle's law; 1663 – Otto von Guericke: first electrostatic generator
The law was named for chemist and physicist Robert Boyle, who published the original law in 1662. The French physicist Edme Mariotte discovered the same law independently of Boyle in 1676. 1671: Newton–Raphson method – Joseph Raphson (1690), Isaac Newton (Newton's work was written in 1671, but not published until 1736).
Blaise Pascal [a] (19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, philosopher, and Catholic writer.. Pascal was a child prodigy who was educated by his father, a tax collector in Rouen.
Pascal made contributions to developments in both hydrostatics and hydrodynamics. Pascal's Law is a fundamental principle of fluid mechanics that states that any pressure applied to the surface of a fluid is transmitted uniformly throughout the fluid in all directions, in such a way that initial variations in pressure are not changed.
Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. [1]: 3 It has applications in a wide range of disciplines, including mechanical, aerospace, civil, chemical, and biomedical engineering, as well as geophysics, oceanography, meteorology, astrophysics, and biology.
The siphon is a simple instrument; but the forcing-pump is a complicated invention, which could scarcely have been expected in the infancy of hydraulics. It was probably suggested to Ctesibius by the Egyptian wheel or Noria , which was common at that time, and which was a kind of chain pump, consisting of a number of earthen pots carried round ...
Therefore, it is important to keep and maintain records that help establish who is first to invent a particular invention. The inventor's notebook (also called a journal, lab book or log book) is a systematic device for recording all information related to an invention in such a way that it can be used to develop a case during a patent ...
