Edwin Herbert Land, ForMemRS, [2] FRPS, Hon.MRI (May 7, 1909 – March 1, 1991) was an American scientist and inventor, [4] best known as the co-founder of the Polaroid Corporation. He invented inexpensive filters for polarizing light, a practical system of in-camera instant photography , and the retinex theory of color vision , among other things.
The American physicist and industrialist Edwin Herbert Land (1909–1991) launches the first instant camera, Polaroid camera Model 95 on the market. Three American engineers at Bell Laboratories (John Bardeen, Walter Brattain and William Shockley) invent the transistor. Its lesser size and power compared with electron tubes brings (from 1955 ...
The Babcock test was the first inexpensive and practical test which were used to determine the fat content of milk. Invented by Stephen Moulton Babcock in 1890, the test was developed to prevent dishonest farmers who could, until the 1890s, water down their milk or remove some cream before selling it to the factories because milk was paid by ...
The Edwin H. Land Medal is jointly presented by The Optical Society and the Society for Imaging Science and Technology (IS&T). [1] The Land Medal was established in 1992 to honor the noted scientist and entrepreneur Edwin H. Land, [2] who is noted for his invention of instant photography, for founding the Polaroid Corporation, and for developing the theory of Retinex, amongst many other ...
Konstantin Konstantinov (1817/1819–1871), Russia – device for measuring flight speed of projectiles, ballistic rocket pendulum, launch pad, rocket-making machine Sergei Korolev (1907–1966), USSR – first successful intercontinental ballistic missile ( R-7 Semyorka ), R-7 rocket family , Sputniks (including the first Earth-orbiting ...
Introduced in 1964, it reached a speed of 210 km/h (130 mph). 1960: The first functioning laser is invented by Theodore Maiman. 1963: The first electronic cigarette is created by Herbert A. Gilbert. Hon Lik is often credited with its invention as he developed the modern electronic cigarette and was the first to commercialize it.
Experimented in aeronautics at age 13 with a Chinese top (1796); [28] first design of a fixed-wing aircraft (1799); [51] used a whirling arm to test aerofoils at varying angles (1804); [51] presented a paper outlining specific design parameters for building a glider (1810); [51] designed, constructed, and had flown (short hop) a tri-plane (1849 ...
Inventor Frederick Adams had forecast that the aerodynamic, "cigar-shaped" train could be run at a speed of 100 miles per hour (160 km/h) with less expenditure than is now required to keep up a speed of 50 miles per hour (80 km/h). [58] However, the train achieved no more than 60 miles per hour (97 km/h). [59]
