Graham offered her correction fluid to IBM, which declined the offer (the company announced its own Correcting Selectric with an integrated lift-off tape in 1973). By 1968, the product – now renamed Liquid Paper – was profitable, and in 1979 the company was sold to the Gillette Corporation for $47.5 million with royalties.
An approximate 'perturbation solution' is obtained by truncating the series, usually by keeping only the first two terms, the solution to the known problem and the 'first order' perturbation correction. Perturbation theory is used in a wide range of fields, and reaches its most sophisticated and advanced forms in quantum field theory.
Flatness refers to the shape of a liquid's free surface. On Earth, the flatness of a liquid is a function of the curvature of the planet, and from trigonometry, can be found to deviate from true flatness by approximately 19.6 nanometers over an area of 1 square meter, a deviation which is dominated by the effects of surface tension.
When searching for a signal in a continuous parameter space there can also be a problem of multiple comparisons, or look-elsewhere effect. For example, a physicist might be looking to discover a particle of unknown mass by considering a large range of masses; this was the case during the Nobel Prize winning detection of the Higgs boson.
Bernoulli's principle is a key concept in fluid dynamics that relates pressure, speed and height. Bernoulli's principle states that an increase in the speed of a parcel of fluid occurs simultaneously with a decrease in either the pressure or the height above a datum. [1]:
The Wicked Bible The Judas Bible in St. Mary's Church, Totnes, Devon, UK. The Wicked Bible omits the word "not" in the commandment, "thou shalt not commit adultery".. The Judas Bible is a copy of the second folio edition of the authorized version, printed by Robert Barker, printer to James VI and I, in 1613, and given to the church for the use of the Mayor of Totnes.
The 2019 Malawian general election was nullified by the Constitutional Court in 2020 because many results were changed by use of correction fluid, as well as duplicate, unverified and unsigned results forms. [55] [56] California allows correction fluid and tape, so changes can be made after the ballot leaves the voter. [57]
Bénard cells. In fluid thermodynamics, Rayleigh–Bénard convection is a type of natural convection, occurring in a planar horizontal layer of fluid heated from below, in which the fluid develops a regular pattern of convection cells known as Bénard cells.
