Le mot "volonté" de l'oeuvre de DESCARTES
LE MONDE OU TRAITÉ DE LA LUMIERE, CHAPITRE XIII, De la lumière. Et pour cela il faut savoir que lorsque je dis qu'un corps tend vers quelque côté, je ne veux pas pour cela qu'on s'imagine qu'il aiten soi une pensée ou une volonté qui l'y porte, mais seulement qu'il est disposé à se mouvoir vers là, soit que véritablement il s'ymeuve, soit plutôt que quelque autre corps l'en empêche ; MEDITATIONS METAPHYSIQUES, REPONSES DE L'AUTEUR AUX SECONDES OBJECTIONS, RAISONS QUI...

L'oreille perçoit aisément la différence entre deux voix ou entre deux instruments émettant la même note. À fréquence et intensité égales, les sons sont différents. On dit qu'ils n'ont pas le même timbre. Cette différence s'explique grâce à l'analyse qu'a faite Fourier des signaux périodiques, qui no...

ATMOSPHÈRE
GÉNÉRALITÉS
DESCRIPTION
L'atmosphère est la couche gazeuse qui entoure notre planète et qui s'étend de sa
surface jusqu'à une hauteur difficile à établir, mais que, par convention, on place à
environ 1 000 km d'altitude.
2 La vapeur d’eau se concentre près de la surface terrestre, où elle peut atteindre 4 % du volume de toute l'atmosphère, mais elle est pratiquement absente au- dessus de 10 km. L’eau sous forme de vapeur n’est pas un constituant passif, mais elle interagit avec le rayonnement solaire et avec l’énergie réémise par la Terre chauffée par le Soleil. La quantité de vapeur d’eau qui peut rester dans l'atmosphère dépend de la température. En général, l’air chaud contient plus de vapeur d’eau que l’air...

Detroit - geography.
Automobile industrialist Henry Ford was born near Dearborn, Michigan, in 1863. Ford built his first automobile in 1893 and establishedhis own manufacturing company ten years later. The Ford Company headquarters are in Dearborn, as is the Henry Ford Museum,shown here, which tells of the transition of the United States from an agricultural to an industrial society, a change in which Fordplayed a central part.Townsend P.

divergent tout autour mais qui sont rarement longs, faute d'alimentation ; leur forme dépend de la topographie : glaciers de vallée et glaciers de piémont. 3.3 Les glaciers alpins Les glaciers de type alpin existent dans les montagnes du monde entier dès que celles-ci sont assez élevées pour conserver des neiges permanentes ; les différencesd'englacement dépendent des conditions climatiques zonales et régionales, des volumes de relief supérieurs à la limite des neiges permanentes, de la topogra...

érosion.
En même temps que le lit s'approfondit, il s'élargit parfois. Les berges inscrites dans des matériaux meubles s'éboulent quand elles sont imbibées d'eau, lors des crues ; lescourants les frappent, en particulier dans les courbes, les faisant reculer tandis que les sinuosités s'exagèrent. Ainsi se forment et évoluent les méandres. Cet élargissementdu lit relève de l'érosion latérale. L'eau opère un tri en fonction de sa compétence, ou capacité de transport (taille maximale des alluvions que le co...

Magnetism
I
INTRODUCTION
Magnetism, an aspect of electromagnetism, one of the fundamental forces of nature.
the French physicist Paul Langevin produced a theory regarding the temperature dependence of the magnetic properties of paramagnets (discussed below), which wasbased on the atomic structure of matter. This theory is an early example of the description of large-scale properties in terms of the properties of electrons and atoms.Langevin's theory was subsequently expanded by the French physicist Pierre Ernst Weiss, who postulated the existence of an internal, “molecular” magnetic field inmaterials...

mathématiques - mathématiques.
autres problèmes mathématiques célèbres apparaissent au cours de ce siècle : diviser un angle en trois angles égaux et construire un cube dont le volume est le double d’un cube donné. Ces trois problèmes seront résolus à l’aide d’instruments beaucoup plus complexes qu’une règle et un compas. Ce n’est qu’au XIX e siècle que l’on démontrera qu’il est impossible de les résoudre au moyen de ces deux instruments. Dans la seconde moitié du Ve siècle av. J.-C., une découverte dérangeante est faite :...

Psychoanalysis.
A cornerstone of modern psychoanalytic theory and practice is the concept of anxiety, which institutes appropriate mechanisms of defense against certain dangersituations. These danger situations, as described by Freud, are the fear of abandonment by or the loss of the loved one (the object), the risk of losing the object's love,the danger of retaliation and punishment, and, finally, the hazard of reproach by the superego. Thus, symptom formation, character and impulse disorders, andperversions,...

Burundi - country.
D Way of Life Most Burundians live in self-contained compounds of small round grass huts scattered over the country’s many hills. The rugo , the traditional Tutsi hut, is divided into sections and surrounded by an enclosure and cattle corrals. Families farm scattered plots of land on different soils at different altitudes to minimize crop failure. Thefloors of valleys are avoided due to higher temperatures and tsetse fly infestation. Social roles are largely determined by ethnicity, with the T...

Poverty.
economic and demographic trends, and (7) welfare incentives. A Overpopulation Overpopulation, the situation of having large numbers of people with too few resources and too little space, is closely associated with poverty. It can result from highpopulation density (the ratio of people to land area, usually expressed as numbers of persons per square kilometer or square mile) or from low amounts of resources, or from both. Excessively high population densities put stress on available resources....

From Pride and Prejudice - anthology.
But why Mr Darcy same so often to the Parsonage, it was more difficult to understand. It could not be for society, as he frequently sat there ten minutes togetherwithout opening his lips; and when he did speak, it seemed the effect of necessity rather than of choice—a sacrifice to propriety, not a pleasure to himself. He seldomappeared really animated. Mrs Collins knew not what to make of him. Colonel Fitzwilliam's occasionally laughing at his stupidity, proved that he was generallydifferent, wh...

Saudi Arabia - country.
C Natural Resources Some of the world’s largest oil and natural gas fields lie beneath Saudi Arabia and its offshore waters, representing the country’s most economically important naturalresource. In 2007 Saudi Arabia’s oil reserves were estimated at 264 billion barrels. Before the discovery and exploitation of these reserves in the mid-20th century,Saudi Arabia was one of the poorest countries in the world. Its relatively small population subsisted in a harsh environment with little agricultur...

African American History - U.
In their day-to-day lives, slaves and servants shared similar grievances and frequently formed alliances. Advertisements seeking the return of slaves and servants whohad run away together filled colonial newspapers. When a slave named Charles escaped in 1740, the Pennsylvania Gazette reported that two white servants, a 'Scotch man' and an Englishman, escaped with him. Sometimes interracial alliances involved violence. During Bacon's Rebellion in 1676, slaves and servants took up armsagainst Na...
