Isaac NewtonIINTRODUCTIONIsaac Newton (1642-1727), English physicist, mathematician, and natural philosopher, considered one of the most important scientists of all time.
B Calculus (Newton’s “Fluxional Method”) In 1669 Newton gave his Trinity mathematics professor Isaac Barrow an important manuscript, which is generally known by its shortened Latin title, De Analysi . This work contained many of Newton’s conclusions about calculus (what Newton called his “fluxional method”). Although the paper was not immediately published, Barrowmade its results known to several of the leading mathematicians of Britain and Europe. This paper established Newton as one of the...

Swimming.
the swimmer and the pinky finger should enter the water first. At the same time, the swimmer moves the left arm through the water below the left side of the body.Once in the water, the right arm begins pulling the swimmer forward by bending at the elbow. At the same time the swimmer holds the left arm straight as it reachesthe hip and lifts it out of the water. As the right arm continues to pull, the swimmer rotates slightly onto the right side and swings the left arm up above the head. As the s...

Relativity - astronomy.
beta, for example, might be as large as 0.5, and the mass of the electron doubled. The mass of a rapidly moving electron could be easily determined by measuring thecurvature produced in its path by a magnetic field; the heavier the electron, the greater its inertia and the less the curvature produced by a given strength of field ( see Magnetism). Experimentation dramatically confirmed Einstein's prediction; the electron increased in mass by exactly the amount he predicted. Thus, the kinetic ener...

parts of oxygen by weight, which is a ratio of about 1 to 8, regardless of whether the water came from the Mississippi River or the ice of Antarctica. In other words, acompound has a definite, invariable composition, always containing the same elements in the same proportions by weight; this is the law of definite proportions. Many elements combine in more than one ratio, giving different compounds. In addition to forming water, hydrogen and oxygen also form hydrogen peroxide.Hydrogen peroxide h...

Planetary Science - astronomy.
III ORIGINS AND COMPOSITIONS OF PLANETS Astronomers believe that planetary systems are formed of elemental materials that were created in the interiors of giant stars. Some of this material comes from giantstars that shed material into space as they age. Most of the matter to form planets, however, comes from stars that explode as supernovas and spread debris enrichedwith the heavier chemical elements into space. According to the currently accepted views, the most likely first stage in the evo...

ridges. The Mid-Atlantic Ridge is an underwater mountain range created at a divergent plate boundary in the middle of the Atlantic Ocean. It is part of a worldwidesystem of ridges made by seafloor spreading. The Mid-Atlantic Ridge is currently spreading at a rate of 2.5 cm per year (1 in per year). The mid-ocean ridges today are60,000 km (about 40,000 mi) long, forming the largest continuous mountain chain on earth.

Members of Commons can also present a motion in response to the Budget Speech, which reviews the government’s economicrecord, taxation, and expenditure plans, and to Supply Motions, which concern budgets for individual departments. If a majority of MPs support a no-confidence motion,the government must resign. Also, if Parliament rejects a significant government proposal, the government is expected to resign and request the governor-general to call an election....

Airplane.
For example, the Anglo-French Concorde, a commercial supersonic aircraft, was generally limited to over-water routes, or to those over sparsely populated regions ofthe world. This limitation impacted the commercial viability of the Concorde, which ended its regular passenger service in October 2003. Designers today believe theycan help lessen the impact of sonic booms created by supersonic airliners but probably cannot eliminate them. One of the most difficult practical barriers to supersonic fl...

R.P.R. (nouvel épisode du conflit entre gaullistes et giscardiens), il ne le vote donc pas, mais s'abstient de soutenir la motion de censure déposée par l'opposition. La motion ne recueillant pas la majorité, la loi passe sans vote. Indiquons que dans l'affrontement qui l'opposera régulièrement aux chiraquiens, R. Barre fera plusieurs fois usage de cet article 49-3. Tout aussi systématiquement le R.P.R., après avoir marqué publiquement son désaccord sur l'un ou l'autre projet de loi, refusera d...

ever-finer method of reducing material to the nanoscale size. Instead, nanostructures would be assembled atom by atom and molecule by molecule, from the atomiclevel up, just as occurs in nature. However, assembly at this scale has its own challenges. In school, children learn about some of these challenges when they study the random Brownian motion seen in particles suspended in liquids such as water. Theparticles themselves are not moving. Rather, the water molecules that surround the particles...

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...

Galileo

INTRODUCTION
Galileo (1564-1642), Italian physicist and astronomer who, with German astronomer Johannes Kepler, initiated the scientific revolution that flowered in the work of
English physicist Sir Isaac Newton.
V WORK IN ASTRONOMY During most of his time in Padua, Galileo showed little interest in astronomy, although in 1595 he declared in a letter that he preferred the Copernican theory that Earthrevolves around the Sun to the assumptions of Aristotle and Ptolemy that planets circle a fixed Earth ( see Astronomy: The Copernican Theory ; Ptolemaic System). A Observations with the Telescope In 1609 Galileo heard that a telescope had been invented in Holland. In August of that year he constructed a t...

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...

Mars (planet) - astronomy.
The Martian core is probably much like Earth’s, consisting mostly of iron, with a small amount of nickel. If other light elements, particularly sulfur, exist there as well, thecore may be larger than presently thought. From studying Earth’s magnetic field and core, scientists theorize that the motions of the liquid rock in Earth’s core generateits magnetic field. Mars does not have a significant magnetic field, so scientists believe that Mars’s core is probably solid. However, spacecraft data in...

L'article 16 est-il une protection ou un danger pour l'ordre constitutionnel défini par la loi fondamentale de 1958 ? (droit)
a. Des limites subjectives L'article 16 précise en effet que « Ces mesures doivent être inspirées par la volonté d'assurer aux pouvoirs publics constitutionnels, dans les moindres délais, lesmoyens d'accomplir leur mission. » • Pour cette raison, il a souvent été dit que cette mesure était plus une mesure « conservatoire » qu'autre chose : le Président de la République n'a pas véritablement àprendre véritablement le pouvoir, mais à assurer que l'ordre normal des choses puisse reprendre son cours...

Lorsque l’assemblée nationale parle « d’un aventurier », on peut y voir une référence à Napoléon III. En effet, le suffrage universel direct...

INTRODUCTION
Modern Dance, tradition of theatrical dance unique to the 20th century.
Though both had their own interests and styles, their collaboration helped establish modern dance as a 20th-century artform. Shawn helped overcome prejudices against men in the new field of modern dance.E.O. Hoppé/Corbis Because a dance language involves elements such as posture, use of the body’s weight, and the character of movements (sinuous, angular, and so forth)—as well asspecific movements of the head, torso, hands, arms, legs, and feet—most creators of modern dance have considered it ess...
