In 1726 Isaac Newton became one of the first aerodynamicists in the modern sense when he developed a theory of air resistance which was later verified for low flow speeds. Air resistance experiments were performed by investigators throughout the 18th and 19th centuries, aided by the construction of the first wind tunnel in 1871.
In the Greek school at Alexandria, which flourished under the auspices of the Ptolemies, attempts were made at the construction of hydraulic machinery, and about 120 BC the fountain of compression, the siphon, and the forcing-pump were invented by Ctesibius and Hero. The siphon is a simple instrument; but the forcing-pump is a complicated ...
Newton's analysis of this book, which he made in Cambridge while protecting himself from London's 1665–1666 infection, is the most substantial written statement he is known to have made about the plague, according to Bonhams. As far as the therapy is concerned, Newton writes that "the best is a toad suspended by the legs in a chimney for ...
Sir Isaac Newton (1642–1727) Cambridge University physicist and mathematician Sir Isaac Newton (1642–1727) was a fellow of the Royal Society of England, who created a single system for describing the workings of the universe.
Commonly cited examples of multiple independent discovery are the 17th-century independent formulation of calculus by Isaac Newton, Gottfried Wilhelm Leibniz and others, described by A. Rupert Hall; [3] the 18th-century discovery of oxygen by Carl Wilhelm Scheele, Joseph Priestley, Antoine Lavoisier and others; and the theory of the evolution ...
1672: Sir Isaac Newton: discovers that white light is a mixture of distinct coloured rays (the spectrum). 1673: Christiaan Huygens: first study of oscillating system and design of pendulum clocks; 1675: Leibniz, Newton: infinitesimal calculus. 1675: Anton van Leeuwenhoek: observes microorganisms using a refined simple microscope.
