It had been pointed out previously by J. J. Thomson in his series of lectures at Yale University in May 1903 that the dynamic equilibrium between the velocity generated by a concentration gradient given by Fick's law and the velocity due to the variation of the partial pressure caused when ions are set in motion " gives us a method of determining Avogadro's Constant which is independent of any hypothesis as to the shape or size of molecules, or of the way in which they act upon each other ".

Euler is the only mathematician to have two numbers named after him: the immensely important Euler's Number in calculus, e, approximately equal to 2. 71828, and the Euler-Mascheroni Constant γ ( gamma ) sometimes referred to as just " Euler's constant ", approximately equal to 0. 57721.

The history of quantum chemistry essentially began with the 1838 discovery of cathode rays by Michael Faraday, the 1859 statement of the black body radiation problem by Gustav Kirchhoff, the 1877 suggestion by Ludwig Boltzmann that the energy states of a physical system could be discrete, and the 1900 quantum hypothesis by Max Planck that any energy radiating atomic system can theoretically be divided into a number of discrete energy elements ε such that each of these energy elements is proportional to the frequency ν with which they each individually radiate energy and a numerical value called Planck ’ s Constant.

Constant False Alarm Rate, a form of Automatic Gain Control ( AGC ), is a method that relies on clutter returns far outnumbering echoes from targets of interest.

French offers a closer pun: " Constant " is both a first name and the quality of steadfastness, thus the play is commonly known as De l ' importance d ' être Constant, though Jean Anouilh translated the play under the title: Il est important d ' être Aimé (" Aimé " is a name which also means " beloved ").

By contrast, a Cosmological Constant is static, with a fixed energy density and w < sub > q </ sub > = − 1.

* Constant rule: If c is a constant, then

Constant flux calorimetry ( or COFLUX as it is often termed ) is derived from heat balance calorimetry and uses specialized control mechanisms to maintain a constant heat flow ( or flux ) across the vessel wall.

Constant reclassification of the 85 reported species has resulted in a considerably smaller number of distinct species, as there is a great deal of disagreement today between systematists over classification.

The Constant Item Purchasing Power Accounting model is an International Accounting Standards Board approved alternative basic accounting model to the traditional Historical Cost Accounting model.

The IASB requires entities to implement IAS 29 which is a Constant Purchasing Power Accounting model during hyperinflation.

Distilled water is also used in Constant Positive Airway Pressure ( CPAP ) machines.

Constant folding is the process of simplifying constant expressions at compile time.

Constant folding can be done in a compiler's front end on the IR tree that represents the high-level source language, before it is translated into three-address code, or in the back end, as an adjunct to constant propagation.

Constant propagation is the process of substituting the values of known constants in expressions at compile time.

ATLAS-3 instruments, mounted on a Spacelab pallet in the cargo bay, included Atmospheric Trace Molecule Spectroscopy ( ATMOS ), which collected more data on trace gases in the atmosphere than on all three of its previous flights combined ; Shuttle Solar Backscatter Ultraviolet Spectrometer ( SSBUV ), which took ozone measurements to calibrate ozone monitor on aging NOAA-9 satellite as well as cooperative measurements with other ATLAS-3 instruments ; Active Cavity Radiometer Irradiance Monitor ( ACRIM ), which took extremely precise measurements of the sun's total radiation for 30 orbits as calibration reference for sister instrument on Upper Atmosphere Research Satellite ( UARS ) launched in 1991 ; Measurement of the Solar Constant ( SOLCON ), provided by Belgium, which also measured solar radiation but as reference point to track changes over years ; Solar Spectrum Measurement ( SOLSPEC ), French instrument, measured sun's radiation as function of wavelength ; and Solar Ultraviolet Spectral Irradiance Monitor ( SUSIM ), which collected its highest precision solar ultraviolet radiation measurements in its 15-year lifetime.

According to Karl Mannheim's historical reconstruction of the shifts in the meaning of ideology, the modern meaning of the word was born when Napoleon Bonaparte ( as a politician ) used it in an abusive way against " the ideologues " ( a group which included Cabanis, Condorcet, Constant, Daunou, Say, Madame de Staël, and Tracy ), to express the pettiness of his ( liberal republican ) political opponents.

Constant wars with many of the major powers in Europe rendered a significant marriage with a foreign princess unlikely, or so Louis XIV told his brother, Monsieur, when persuading him to accept the king's legitimised daughter, Françoise Marie de Bourbon ( known as Mademoiselle de Blois ), as wife for Philippe.

Constant propagation can also cause conditional branches to simplify to one or more unconditional statements, when the conditional expression can be evaluated to true or false at compile time to determine the only possible outcome.

* Constant Lambert's ballet Horoscope was being performed in the Netherlands in 1940, and the unpublished full score had to be left behind when German forces invaded that country.

She danced and acted at various Dublin theatres until 1740, when her success as Sir Harry Wildair in The Constant Couple led to her being given her London debut at Covent Garden ; she became well known as an actress thereafter.

# Constant Comparison Analysis, or called " coding system ": Coding enables the researcher to locate and bring together similarly labelled data for examination and to retrieve data related to more than one label when wanting to consider patterns, connections, or distinctions between them.

Dylan would leave most of these songs behind when he moved to the concert stage in 1963, but he performed " Man of Constant Sorrow " during his first national television appearance in mid-1963 ( a performance included on the 2005 retrospective No Direction Home ).

Constant touring and concert appearances had built up a strong fan base by mid 1981, when the small amount of soul music cover versions were outnumbered by the band's own tracks.

Constant use of only the parking pawl, especially when parking on a steep incline, means that driveline components, and transmission internals, are kept constantly under stress, and can cause wear and eventual failure of the parking pawl or transmission linkage.

This way the large HMS Golden Phoenix and HMS House of Sweden ( the former VOC – ships Gulden Phenix and Huis van Swieten ) and HMS Welcome and HMS Leicester were lost and the smaller Constant John, Unicorn and John and Sarah ; when this was shown by Spragge, personally sounding the depth of a second channel despite the assurances by Pett, to be insufficient, they were joined by the Barbados Merchant, Dolphin, Edward and Eve, Hind and Fortune.

* In her New Yorker review of A. A. Milne's The House at Pooh Corner ( 1928 ) Dorothy Parker, writing under the book reviewer pen name Constant Reader, purposefully mimics baby talk when dismissing the book's syrupy prose style: " It is that word ' hummy ,' my darlings, that marks the first place in The House at Pooh Corner at which Tonstant Weader fwowed up.

Constant lowering of tolls meant that the carriage of some bulky, non-perishable, and non-vital goods by water was still feasible on some inland waterways – but the death knell for commercial carrying on the narrow canals was sounded in the winter of 1962 – 1963, when a long hard frost kept goods icebound on the canals for three months.

Constant touring coupled with their decision to manage themselves hampered the group's creative output, which was already slow due to Gavurin and Wheeler, the main songwriters, " being chained by pokiness and perfectionism when it to writing and recording music.

In theoretical physics, when Einstein originally tried to produce a general theory of relativity, he found that the theory seemed to predict the gravitational collapse of the universe: it seemed that the universe should either be expanding or collapsing, and to produce a model in which the universe was static and stable ( which seemed to Einstein at the time to be the " proper " result ), he introduced an expansionist variable ( called the Cosmological Constant ), whose sole purpose was to cancel out the cumulative effects of gravitation.

" O ' Neil, though, expressed concern that the U. S .' s reluctance to completely sever relations with FRAPH until 1995 ( when Constant was arrested ) may have allowed several high-profile figures to go into hiding.
