For him, the fact that his theory gave a straightforward explanation of the anomalous perihelion shift of the planet Mercury, discovered earlier by Urbain Le Verrier in 1859, was important evidence that he had at last identified the correct form of the gravitational field equations.

* 1811 – Urbain Le Verrier, French mathematician ( d. 1877 )

In the 1840s, the French mathematician Urbain Le Verrier used Newtonian mechanics to analyse perturbations in the orbit of Uranus, and hypothesised that they were caused by the gravitational pull of a yet-undiscovered planet.

On 23 September 1846, the night following his receipt of the letter, Galle and his student Heinrich d ' Arrest discovered Neptune, exactly where Le Verrier had predicted.

In 1848, Jacques Babinet raised an objection to Le Verrier's calculations, claiming that Neptune's observed mass was smaller and its orbit larger than Le Verrier had initially predicted.

Le Verrier denounced Babinet's hypothesis, saying, " is absolutely nothing by which one could determine the position of another planet, barring hypotheses in which imagination played too large a part.

* 1877 – Urbain Le Verrier, French mathematician ( b. 1811 )

* September 23 – Discovery of Neptune: The planet is observed for the first time by German astronomers Johann Gottfried Galle and Heinrich Louis d ' Arrest as predicted by the British astronomer John Couch Adams and the French astronomer Urbain Le Verrier.

Calculations by both John Couch Adams and Urbain Le Verrier predicted the general position of the planet, and Le Verrier's calculations are what led Johann Gottfried Galle to the discovery of Neptune.

In an attempt to explain peculiarities of Mercury's orbit, in the 19th-century French mathematician Urbain Jean Joseph Le Verrier hypothesized that they were the result of another planet, which he named Vulcan.

In 1840, François Arago, the director of the Paris Observatory, suggested to the French mathematician Urbain Jean Joseph Le Verrier that he work on the topic of the planet Mercury's orbital motion around the Sun.

By 1843, Le Verrier published his provisional theory on the subject, which would be tested during a transit of Mercury across the face of the Sun in 1843.

Le Verrier renewed his work and, in 1859, published a more thorough study of Mercury's motion.

Le Verrier postulated that the excess precession could be explained by the presence of a small planet inside the orbit of Mercury, and he proposed the name " Vulcan " for this object.

In December 1859, Le Verrier received a letter from a French physician and amateur astronomer called Edmond Modeste Lescarbault, who claimed to have seen a transit of the hypothetical planet earlier in the year.

Le Verrier took the train to the village of Orgères-en-Beauce, some 70 kilometres southwest of Paris, where Lescarbault had built himself a small observatory.

Le Verrier arrived unannounced and proceeded to interrogate the man.

Le Verrier thought he was satisfied that Lescarbault had seen the transit of a previously unknown planet.

Based on Lescarbault ’ s " transit ", Le Verrier computed Vulcan ’ s orbit: it supposedly revolved about the Sun in a nearly circular orbit at a distance of 21 million kilometres, or 0. 14 astronomical units.

Numerous reports — all of them unreliable — began to reach Le Verrier from other amateurs who claimed to have seen unexplained transits.

Nevertheless, Le Verrier continued to tinker with Vulcan ’ s orbital parameters as each new reported sighting reached him.

Le Verrier would assist Berlin Observatory astronomer Johann Gottfried Galle in locating the planet on 23 September 1846, which was found within 1 ° of its predicted location, a point in Aquarius.

It reached Galle on 23 September and in it Le Verrier asked him to look at a certain region of sky to find a predicted new planet, which would explain the perturbations of the planet Uranus.

Not concluding that Newton's law of universal gravitation was flawed, however, astronomers John Couch Adams as well as Urbain Le Verrier independently predicted a new planet, calculated its weight and orbit through Newton's theory, and so was discovered the planet Neptune where predicted.

Le Verrier soon reported that Mercury's perihelion — the peak of its orbital ellipse nearest to the Sun — advanced each time Mercury completed an orbit, a phenomenon not predicted by Newton's theory, which astrophysicists were so confident in that they predicted a new planet, named Vulcan.

In 1888 Paul du Bois-Reymond argued against Le Sage's model, partly because the predicted force of gravity in Le Sage's theory is not strictly proportional to mass.

* August 31-Urbain Le Verrier publishes full details of the predicted orbit and the mass of the new planet.

In the 1850s, Urbain Le Verrier made detailed calculations of Mercury's orbit and found a small discrepancy in the planet's perihelion precession from predicted values.

Other notable works by Grousset published under the Laurie pseudonym include De New York à Brest en Sept Heures York to Brest In Seven Hours ( 1888 ), which predicted a transatlantic tunnel ; Le Secret du Mage Secret Of The Magician ( 1890 ), in which evidence of an advanced prehistoric is discovered ; Le Rubis du Grand Lama Ruby Of The Great Lama ( 1894 ), which features a steam-powered flying island ; Atlantis ( 1895 ), which describes how the mythical kingdom has survived under a glass dome at the bottom of the sea near the Azores ; Le Maître de l ' Abîme Master Of The Abyss ( 1905 ), which features a revolutionary submarine, and finally Spiridon le Muet The Mute ( 1907 ), a remarkable novel about a human-sized, intelligent ant.

The next ring is named the Le Verrier ring after Urbain Le Verrier, who predicted Neptune's position in 1846.

It is named after John Couch Adams, who predicted the position of Neptune independently of Le Verrier.

For example, in 1929 he was forced to retract an accusation that Martin Wagner's primary activity as chief of city planning for Berlin was funnelling architectural commissions to extremist friends, and he labeled Le Corbusier's Ville Contemporaine project for transforming Paris " only vieux jeu " ( old hat ) and sarcastically predicted that it was likely to be realized,

In it, the assassin's sword was seen hanging by a single strand of horsehair above Le Peletier's body, a concept inspired by the proverbial ancient tale of the sword of Damocles, which illustrated the insecurity of power and position.

Soon he would begin his own architectural practice with his cousin, Pierre Jeanneret ( 1896 – 1967 ), a partnership that would last until the 1950s, with an interruption in the WWII years, due to Le Corbusier's ambivalent position towards the Vichy regime.

During the Vichy regime, Le Corbusier received a position on a planning committee and made designs for Algiers and other cities.

Le Pen himself and the rest of his party disagree with this label ; earlier in his political career, Le Pen described his position as " neither left nor right, but French " ( ni droite, ni gauche, français ).

At the 2007 24 Hours of Le Mans, Stéphane Sarrazin secured pole position but the 908s proved unreliable and ceded victory to Audi.

The first step required the capture of the German Transloy Line, effectively the German fourth defensive position that ran from the village of Le Transloy in the east to Le Sars on the Albert-Bapaume road.

Nicknamed " Le Tigre " ( The Tiger ), he took a very harsh position against defeated Germany and argued for the payment of reparations.

By October 1982, Le Pen supported the prospect of deals with the mainstream right, provided that the FN did not have to soften its position on key issues.

In the tenth FN national congress in 1997, Mégret stepped up his position in the party as its rising star and a potential leader following Le Pen.

Henri Le Caron, who, while acting as a secret agent of the British government, held the position of " Inspector-General of the Irish Republican Army ," asserts that he distributed fifteen thousand stands of arms and almost three million rounds of ammunition in the care of the many trusted men stationed between Ogdensburg, New York and St. Albans, Vermont, in preparation for the intended raid.

Rather than remain at the studio for further tuition Le Mesurier decided to leave and take a position in repertory theatre with the Edinburgh-based Millicent Ward Repertory Players, earning £ 3. 10s a week.

After the Second Gulf War starting in 2003 under the George W. Bush administration, Le Monde diplomatique continues its position of criticizing the US policy of " violent intervention " in the Middle East and the neoconservative ' project to " reshape " the so-called " Greater Middle East " region.

The Voltaire Network, which has somehow changed position since the September 11 attacks and whose director, Thierry Meyssan, became a leading proponent of 9 / 11 conspiracy theory, explained that although the Norwegian version of Le Monde diplomatique had allowed it to translate and publish this article on its website, the mother-house, in France, categorically refused it this right, thus displaying an open debate between various national editions.
