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.

Le Verrier predicted the position of this new planet and sent his calculations to German astronomer Johann Gottfried Galle.

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.

* 1846 – Astronomers Urbain Jean Joseph Le Verrier, John Couch Adams and Johann Gottfried Galle collaborate on the discovery of Neptune.

* 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.

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.

He postulated, based largely on simple subtraction from Le Verrier's calculations, that another planet of roughly 12 Earth masses, which he named " Hyperion ", must exist beyond Neptune.

Therefore, in order to be viable, Fatio and Le Sage postulated that the shielding effect is so small as to be undetectable, which requires that the interaction cross-section of matter must be extremely small ( P10, below ).

* 1855 – Le Verrier observes a 35 arcsecond per century excess precession of Mercury's orbit and attributes it to another planet, inside Mercury's orbit.

Le Brocquy is widely acclaimed for his evocative " Portrait Heads " of literary figures and fellow artists, which include William Butler Yeats, James Joyce, and his friends Samuel Beckett, Francis Bacon and Seamus Heaney, in recent years le Brocquy's early " Tinker " subjects and Grey period " Family " paintings, have attracted attention on the international marketplace placing le Brocquy within a very select group of British and Irish artists whose works have commanded prices in excess of £ 1 million during their lifetimes that include Lucian Freud, David Hockney, Frank Auerbach, and Francis Bacon.

From 1466 on, Le Thanh Tong declared excess surplus set as 12, which includes three government Xinghua, four districts and 17 European.

The racing MC12s were entered into the American Le Mans Series races in 2005 but exceeded the size restrictions and consequently paid weight penalties due to excess range.

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.

This anomalous rate of precession of the perihelion of Mercury's orbit was first recognized in 1859 as a problem in celestial mechanics, by Urbain Le Verrier.

It could be said that Aalto's international reputation was sealed with his inclusion in the second edition of Sigfried Giedion's influential book on Modernist architecture, Space, Time and Architecture: The growth of a new tradition ( 1949 ), in which Aalto received more attention than any other Modernist architect, including Le Corbusier.

Le Page's description of Moncacht-Apé's route across the continent, which neglects to mention the need to cross the Rocky Mountains, may be the source of Lewis and Clark's mistaken belief that they could easily carry boats from the Missouri's headwaters to the westward-flowing Columbia.

In 1867, three years before it happened, for example, Le Pelletier did so to anticipate either the triumph or the defeat of Napoleon III in a war that, in the event, begged to be identified as the Franco-Prussian war, while admitting that he could not specify either which or when.

Germaine Tailleferre of the French group Les Six wrote several works which could be considered to be inspired by Surrealism, including the 1948 Ballet Paris-Magie ( scenario by Lise Deharme ), the Operas La Petite Sirène ( book by Philippe Soupault ) and Le Maître ( book by Eugène Ionesco ).

After the publication of the Méry video-tape by Le Monde on 22 September 2000, in which Jean-Claude Méry, in charge of the RPR's financing, directly accused Chirac of organizing the network, and of having been physically present on 5 October 1986, when Méry gave in cash 5 millions Francs, which came from companies who had benefited from state deals, to Michel Roussin, personal secretary ( directeur de cabinet ) of Chirac, Chirac refused to follow up his summons by judge Eric Halphen, and the highest echelons of the French justice declared that he could not been inculpated while in functions.

In Montparnasse's heyday ( from 1910 to 1920 ), the cafés Le Dôme, La Closerie des Lilas, La Rotonde, Le Select, and La Coupole — all of which are still in business — were the places where starving artists could occupy a table all evening for a few centimes.

The dean of Rouen recovered the body from the chapter of Le Mans a month later by law suit so the Young Henry could be buried in Normandy as he had desired in his testament.

Martin was a committed anti-Communist, but he seriously underestimated the severity of the South Vietnamese situation, to the point that in the spring of 1975, when most American officials were convinced that South Vietnam was doomed to collapse, he continued to believe that Saigon and the Mekong Delta area could be held because of the tenacity of the Army of the Republic of Vietnam ( ARVN ) in the Battle of Xuan Loc under the command of General Le Minh Dao.
