Bradwardine, Thomas
velocity is a self-contradiction, a vacuum is impossible. In De proportionibus , Bradwardine first laid out the theory of ratios familiar from the theory of musical ratios as found in Boethius . He used this understanding of operations on ratios to reinterpret Aristotle 's theory. Velocities vary, he said, as the ratio of force to resistance. When the ratio of force to resistance is ‘doubled' the velocity is doubled, when the ratio is ‘tripled' the velocity is tripled and so on, with the...

Sound
I
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...

Trigonometry
I
INTRODUCTION
Trigonometry, branch of mathematics that deals with the relationships between the sides and angles of triangles and with the properties and applications of the
trigonometric functions of angles.
If point P, in the definition of the general trigonometric function, is on the y-axis, x is 0; therefore, because division by zero is inadmissible in mathematics, the tangent and secant of such angles as 90°, 270°, and -270° do not exist. If P is on the x-axis, y is 0; in this case, the cotangent and cosecant of such angles as 0°, 180°, and - 180° do not exist. All angles have sines and cosines, because r is never equal to 0. Since r is greater than or equal to x or y, the values of si...

logistique : Une gestion pertinente des compétences des ressources humaines et la mise en place de relations de collaboration entre une entreprise et ses partenaires de chaîne logistique 3 . Cependant la chaine logistique n’est elle pas un pilier pour améliorer la compétitivité de l’entreprise au national et a l’international ? Intérêt L’objectif de cette thèse est donc de proposer un repere s’appuyant sur ces deux inducteurs pour formaliser une démarche d’évaluation de la performa...

Internal-Combustion Engine.
any Otto-cycle engine and in actual engines today is slightly more than 40 percent. Diesels are, in general, slow-speed engines with crankshaft speeds of 100 to 750revolutions per minute (rpm) as compared to 2500 to 5000 rpm for typical Otto-cycle engines. Some types of diesel, however, have speeds up to 2000 rpm. Becausediesels use compression ratios of 14 or more to 1, they are generally more heavily built than Otto-cycle engines, but this disadvantage is counterbalanced by theirgreater effici...

of sediment. When studied in sedimentary core samples, which can represent many millions of years of deposits, they provide a detailed and continuous history of theearth’s environmental changes. The record is particularly informative for the most recent 2 million to 5 million years, during which major fluctuations in global climatehave occurred. Successive ice ages can be traced by the relative scarcity or abundance of the shells of warm-water and cold-water diatoms in various layers of asedimen...
