I asked Quasimodo recently how he accomplished this, and he replied that he had painted his model `` a beautiful shade of red and then had her breathe on the canvas '', which was his typical tongue-in-cheek way of chiding me for my lack of sensitivity.

A decade and a half later, the Polish anthropology student, Bronisław Malinowski ( 1884 – 1942 ), was beginning what he expected to be a brief period of fieldwork in the old model, collecting lists of cultural items, when the outbreak of the First World War stranded him in New Guinea.

non-mathematical explanation of the additive effects model was

In 1911, Ernest Rutherford gave a model of the atom in which a central core held most of the atom's mass and a positive charge which, in units of the electron's charge, was to be approximately equal to half of the atom's atomic weight, expressed in numbers of hydrogen atoms.

Moseley, after discussions with Bohr who was at the same lab ( and who had used Van den Broek's hypothesis in his Bohr model of the atom ), decided to test Van den Broek and Bohr's hypothesis directly, by seeing if spectral lines emitted from excited atoms fit the Bohr theory's demand that the frequency of the spectral lines be proportional to a measure of the square of Z.

The Declaration announced the states ' entry into the international system ; the model treaty was designed to establish amity and commerce with other states ; and the Articles of Confederation, which established “ a firm league ” among the thirteen free and independent states, constituted an international agreement to set up central institutions for the conduct of vital domestic and foreign affairs.

Rutherford interpreted the gold foil experiment as suggesting that the positive charge of a heavy gold atom and most of its mass was concentrated in a nucleus at the center of the atom — the Rutherford model.

This model was able to explain observations of atomic behavior that previous models could not, such as certain structural and spectral patterns of atoms larger than hydrogen.

Thus, the planetary model of the atom was discarded in favor of one that described atomic orbital zones around the nucleus where a given electron is most likely to be observed.

The standard model of particle physics was developed that so far has successfully explained the properties of the nucleus in terms of these sub-atomic particles and the forces that govern their interactions.

The first to arrive was Émile Levassor in his Panhard-Levassor 1205cc model.

In the panentheistic model of process philosophy and theology the writers Alfred North Whitehead and Charles Hartshorne rejected that the universe was made of substance, instead reality is composed of living experiences ( occasions of experience ).

In seeking to explain atomic spectra an entirely new mathematical model of matter was revealed.

Thomson theorized that multiple electrons revolved in orbit-like rings within a positively charged jelly-like substance, and between the electron's discovery and 1909, this " plum pudding model " was the most widely accepted explanation of atomic structure.

Once a prototype has passed the tests at a certification lab, and that model is being constructed under the control of a certified quality system, the device is entitled to bear a CE mark, indicating that the device is believed to be safe and reliable when used as directed.

A hyperbolic model of a coral reef has also been constructed for environmental purposes

This had a glass roof and three glass walls constructed after the model of large studios for still photography, and it was fitted with thin cotton cloths that could be stretched below the roof to diffuse the direct ray of the sun on sunny days.

Sydney Brenner, Jack Dunitz, Dorothy Hodgkin, Leslie Orgel, and Beryl M. Oughton, were some of the first people in April 1953 to see the model of the structure of DNA, constructed by Crick and Watson ; at the time they were working at Oxford University's Chemistry Department.

They constructed an animatronic model of a plesiosaur, and dubbed it " Lucy ".

There are two primary ways of constructing statistical models: in a static model, the data is analyzed and a model is constructed, then this model is stored with the compressed data.

Maxwell himself proposed several mechanical models of aether based on wheels and gears, and George FitzGerald even constructed a working model of one of them.

In 1985, he constructed the pelvi-trainer = laparo-trainer, a practical surgical model whereby colleagues could practice laparoscopic techniques.

The first model constructed by Sholes used a piano-like keyboard with two rows of characters arranged alphabetically as follows:

MacCready constructed a model flying machine or ornithopter with a simple computer functioning as an autopilot.

The design of OV-101 was not the same as that planned for OV-102, the first flight model ; the tail was constructed differently, and it did not have the interfaces to mount OMS pods.

* The Chinese polymath statesman and scientist Su Song has the successful pilot model for his astronomical clock tower constructed in Kaifeng, China.

A major part of Washington's legacy, the model rural schools continued to be constructed, with matching funds from the Rosenwald Fund, into the 1930s.

They were designed, constructed and opened in 1913 and 1914 and overseen by Tuskegee ; the model proved successful.

A modification of Alcubierre's model was recently constructed by Chris van den Broeck of the Catholic University of Louvain in Belgium.

The Japanese Emperor Temmu ( r. 672 – 686 ) even established his conscripted army on that of the Chinese model, his state ceremonies on the Chinese model, and constructed his palace at Fujiwara on the Chinese model of architecture.

From the observed X-ray spectrum, combined with spectral emission results for other wavelength ranges, an astronomical model addressing the likely source of X-ray emission can be constructed.

From the onset, Tolkien used comparative philology and the tree model as his major tools in his constructed languages.

For any normal modal logic L, a Kripke model ( called the canonical model ) can be constructed, which validates precisely the theorems of L, by an adaptation of the standard technique of using maximal consistent sets as models.

In queueing theory a model is constructed so that queue lengths and waiting times can be predicted.
