They also believed that thewealth of a nation depended primarily on the possession...

LE QUARK (Sciences et Techniques)
Dans les années 60, grâce au développement des accélérateurs, la liste des nouvelles particules subatomiquesdécouvertes par les physiciens s'allongea remarquablement. Il devint par conséquent important de comprendres'il existait une structure ordonnée dans laquelle on pût les placer. C'est ce que firent en 1968 Sheldon Glashow,Abdus Salam et Steven Weinberg avec le « modèle standard », qui jusqu'à présent rend compte desobservations expérimentales.

Capitalism.
Physiocracy is the term applied to a school of economic thought that suggested the existence of a natural order in economics, one that does not require direction from the state for people to be prosperous. The leader of the physiocrats, the economist François Quesnay, set forth the basic principles in his Tableau économique (1758), in which he traced the flow of money and goods through the economy. Simply put, this flow was seen to be both circular and self-sustaining. More important, however...

INTRODUCTION
Sound, physical phenomenon that stimulates the sense of hearing.
A fundamental law of harmony states that two notes an octave apart, when sounded together, produce a pleasant-sounding combination. Other combinations of notescan also be pleasing. Physically, an interval of a fifth consists of two notes, the frequencies of which bear the arithmetical ratio 3 to 2, and a major third, the ratio 5 to4. Fundamentally, the law of harmony states that two or more notes sound pleasant when played together if their frequencies bear small, whole number ratios; if thefreq...

Anaxagoras therefore suggested that all things are composed of very small particles, or “seeds,” which exist in infinite variety. To explain the way in whichthese particles combine to form the objects that constitute the familiar world, Anaxagoras developed a theory of cosmic evolution. He maintained that the activ...

This text also shows the development of poetic forms such as the tanka (short poem), a form structured around alternating lines of 5 an...
