But at the end of the sitting, when Michelangelo showed him the quick, free drawings, with the mother roughed in, holding her son, the model grasped what Michelangelo was after, and promised to speak to his friends.

When he showed this model as his `` solution '' as to how the Howe sewing machine operated, he was told he was `` wrong '', and discovered to his amazement that the Howe Machine, which was unknown to him in detail, used two threads while the one that he had perfected used only one.

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.

The magnetic resonance absorption was detected by employing a Varian model Af broad line spectrometer and the associated 12-inch electromagnet system.

One measurement at 40 Mc/sec was obtained with the Varian model Af unit.

Paper electrophoresis was carried out on the concentrated samples in a Spinco model R cell using barbital buffer, pH 8.6, ionic strength 0.075, at room temperature on Whatman 3MM filter paper.

Ultracentrifugation was then carried out in a Spinco model L ultracentrifuge at 40,000 rpm for 125 to 150 min, refrigeration being used throughout the run.

When she said that she didn't have the money, he said that she could come in for treatment with his office model until she was ready to buy one.

His interpretation was a model of refinement and accuracy.

In need of a model for his statuette, Gibbons was introduced by his future wife Dolores del Río to Mexican film director and actor Emilio " El Indio " Fernández.

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.

These results refined Ernest Rutherford's and Antonius Van den Broek's model, which proposed that the atom contains in its nucleus a number of positive nuclear charges that is equal to its ( atomic ) number in the periodic table.

Shortly after, in 1913, Rutherford's postdoctoral student Niels Bohr proposed a new model of the atom, wherein electrons orbited the nucleus with classical periods, but were only permitted to have discrete values of angular momentum, quantized in units h / 2π.

In our current understanding of physics, the Bohr model is called a semi-classical model because of its quantization of angular momentum, not primarily because of its relationship with electron wavelength, which appeared in hindsight a dozen years after the Bohr model was proposed.

* Working from Wernicke's model of aphasia, Ludwig Lichtheim proposed five other types of aphasia, but these were not tested against real patients until modern imaging made more in-depth studies available.

* Anomic aphasia, also known as Anomia, is another type of aphasia proposed under what is commonly known as the Boston-Neoclassical model, which is essentially a difficulty with naming.

The plum pudding model of the atom by J. J. Thomson, who discovered the electron in 1897, was proposed in 1904 before the discovery of the atomic nucleus in order to add the electron to the atomic model.

In this model, the atom is composed of electrons ( which Thomson still called " corpuscles ", though G. J. Stoney had proposed that atoms of electricity be called electrons in 1894 ) surrounded by a soup of positive charge to balance the electrons ' negative charges, like negatively charged " plums " surrounded by positively charged " pudding ".

During the 1930s other ideas were proposed as non-standard cosmologies to explain Hubble's observations, including the Milne model, the oscillatory Universe ( originally suggested by Friedmann, but advocated by Albert Einstein and Richard Tolman ) and Fritz Zwicky's tired light hypothesis.

Further levels of editing have also been proposed, including: a late 8th century edition pointing to Hezekiah of Judah as the model for kingship ; an earlier 8th century version with a similar message but identifying Jehu of Israel as the ideal king ; and an even earlier version promoting the House of David as the key to national well-being.

The proposed encoding does not use the lexical encoding model used in the existing ISO-IR / 169 registered character set, but instead applies the Unicode and ISO character-glyph model to the Bliss-character model already adopted by BCI, since this would significantly reduce the number of needed characters.

In light of these weaknesses, Barnlund ( 2008 ) proposed a transactional model of communication.

The discovery of the cosmic microwave background in 1965 lent strong support to the Big Bang model, and since the precise measurements of the cosmic microwave background by the Cosmic Background Explorer in the early 1990s, few cosmologists have seriously proposed other theories of the origin and evolution of the cosmos.

In this sense they are reminiscent of the oscillatory universe proposed by Richard Chace Tolman: however in Tolman's model the total age of the universe is necessarily finite, while in these models this is not necessarily so.

Paul Drude proposed the first theoretical model for a classical electron moving through a metallic solid.

As a serious proposal, it was first suggested by mathematician John Von Neumann in the late 1940s when he proposed a kinematic self-reproducing automaton model as a thought experiment.

Precise measurements of cosmic background radiation are critical to cosmology, since any proposed model of the universe must explain this radiation.

In his major " state of the art " review of 1855, he proposed a substantially complete and correct model for the etiology of the disease.

The relational model, first proposed in 1970 by Edgar F. Codd, departed from this tradition by insisting that applications should search for data by content, rather than by following links.

Young's experiment, performed in the early 1800s, played a vital part in the acceptance of the wave theory of light, vanquishing the corpuscular theory of light proposed by Isaac Newton, which had been the accepted model of light propagation in the 17th and 18th centuries.

In the 20th century German chemist Walther Nernst proposed a mathematical model to determine the effect of reactant concentration on electrochemical cell potential.
