Kepler also posed the problem in 1610, and the paradox took its mature form in the 18th century work of Halley and Cheseaux.

The name " saros " () was first given to the eclipse cycle by Edmond Halley in 1691, who took it from the Suda, a Byzantine lexicon of the 11th century.

Another impact destroyed the Halley Multicolor Camera, but not before it took photographs of the nucleus at closest approach.

Vega mission descriptionThe Vega program was a series of Venus missions which also took advantage of the appearance of Comet Halley in 1986.

Deciding not to wait, Clarke instead took his inspiration from the approach of Comet Halley in 1986 and focused his sequel on the comet's future return, in 2061.

" While Harris's work is often classified as a technical dictionary, it also took material from Newton and Halley among others.

Many visitors have been to Martim Vaz, the most famous of whom was the English astronomer Edmund Halley, who took possession of the island on behalf of the British Monarchy in 1700.

The inquest into the death of Paul-Louis Halley took place in Oxford, England, in late October 2005.

They later took part in the " Halley en Obras ", along with other bands: Alakrán (" Skorpion "), JAF and Kamikaze, in 1988.

When Halley asked Newton's opinion on the problem of planetary motions discussed earlier that year between Halley, Hooke and Wren, Newton surprised Halley by saying that he had already made the derivations some time ago ; but that he could not find the papers.

It appears that Hooke professed to have a solution of the problem of the path of a body moving round a centre of force attracting as the inverse square of the distance, but Halley declared after a delay of some months that Hooke " had not been so good as his word " in showing his solution to Wren, and started for Cambridge, in the month of August 1684, to consult Newton on the subject.

In the following November Newton redeemed his promise to Halley by sending him, by the hand of Mr Paget, one of the fellows of his own college, and at that time mathematical master of Christ's Hospital, a copy of his demonstration ; and very soon afterwards Halley paid another visit to Cambridge to confer with Newton about the problem.

This method of designating stars first appeared in a preliminary version of John Flamsteed's Historia Coelestis Britannica which was published by Edmond Halley and Isaac Newton in 1712 without Flamsteed's approval.

Along with the inventor and microscopist Robert Hooke ( 1635 – 1703 ), Sir Christopher Wren ( 1632 – 1723 ) and Sir Isaac Newton ( 1642 – 1727 ), English scientist and astronomer Edmond Halley ( 1656 – 1742 ) was trying to develop a mechanical explanation for planetary motion.

Hooke remained bitter about Newton claiming the invention of this principle, even though Newton ’ s “ Principia ” acknowledged that Hooke, along with Wren and Halley, had separately appreciated the inverse square law in the solar system, as well as giving some credit to Bullialdus.

In 1712, Isaac Newton, then President of the Royal Society, and Edmund Halley obtained the data and published a pirated star catalogue.

Wren was unconvinced, Hooke did not produce the claimed derivation although the others gave him time to do it, and Halley, who could derive the inverse-square law for the restricted circular case ( by substituting Kepler's relation into Huygens ' formula for the centrifugal force ) but failed to derive the relation generally, resolved to ask Newton.

( Matching accounts of this meeting come from Halley and Abraham De Moivre to whom Newton confided.

) Halley then had to wait for Newton to ' find ' the results, but in November 1684 Newton sent Halley an amplified version of whatever previous work Newton had done on the subject.

The contents of ' De motu ...' so excited Halley by their mathematical and physical originality and far-reaching implications for astronomical theory, that he immediately went to visit Newton again, in November 1684, to ask Newton to let the Royal Society have more of such work.

When Hooke's claim was made known to Newton, who hated disputes, Newton threatened to withdraw and suppress Book 3 altogether, but Halley, showing considerable diplomatic skills, tactfully persuaded Newton to withdraw his threat and let it go forward to publication.

Newton acknowledged Wren, Hooke and Halley in this connection in the Scholium to Proposition 4 in Book 1.

Newton also acknowledged to Halley that his correspondence with Hooke in 1679-80 had reawakened his dormant interest in astronomical matters, but that did not mean, according to Newton, that Hooke had told Newton anything new or original: " yet am I not beholden to him for any light into that business but only for the diversion he gave me from my other studies to think on these things & for his dogmaticalness in writing as if he had found the motion in the Ellipsis, which inclined me to try it ...".

Halley showed that the evaporation from the Mediterranean Sea was sufficient to account for the outflow of rivers flowing into the sea.

The precise recordkeeping of births and deaths by the city of Breslau led to the use of their data for analysis of mortality, first by John Graunt, and then later by Edmond Halley.

Some comets contain " massive amounts of an organic material almost identical to high grade oil shale ," the equivalent of cubic kilometers of such mixed with other material ; for instance, corresponding hydrocarbons were detected in a probe fly-by through the tail of Comet Halley during 1986.

Mathematicians, such as Edmond Halley, developed the life table as the basis for life insurance mathematics.

Halley's 1910 apparition is distinct from the Great Daylight Comet of 1910, which surpassed Halley in brilliance and was actually visible in broad daylight for a short period, approximately four months before Halley made its appearance.

On 12 February 1991, at a distance of from the Sun, Halley displayed an outburst that lasted for several months, releasing a cloud of dust 300, 000 km across.

The telescopes observed Halley, at the faintest and furthest any comet has ever been imaged, in order to verify a method for finding very faint trans-Neptunian objects.

He also gives starting at Lemma 4 and Proposition 40 ) the theory of the motions of comets ( for which much data came from John Flamsteed and from Edmond Halley ), and accounts for the tides, attempting quantitative estimates of the contributions of the Sun and Moon to the tidal motions ; and offers the first theory of the precession of the equinoxes.

The first of the three constituent books was sent to Halley for the printer in spring 1686, and the other two books somewhat later.

Newton also acknowledged to Halley that his correspondence with Hooke in 1679 – 80 had reawakened his dormant interest in astronomical matters, but that did not mean, according to Newton, that Hooke had told Newton anything new or original: " yet am I not beholden to him for any light into that business but only for the diversion he gave me from my other studies to think on these things & for his dogmaticalness in writing as if he had found the motion in the Ellipsis, which inclined me to try it.

Wren's challenge to Halley and Hooke, for the reward of a book worth thirty shillings, was to provide, within the context of Hooke's hypothesis, a mathematical theory linking the Kepler's laws with a specific force law.

After further encouragement from Halley, Newton went on to develop and write his book Philosophiæ Naturalis Principia Mathematica ( commonly known as the Principia ) from a nucleus that can be seen in ' De Motu ' – of which nearly all of the content also reappears in the Principia.

Newton replied promptly, " an ellipse ", and on being questioned by Halley as to the reason for his answer he replied, " Why, I have calculated it.

* 1684 – Isaac Newton's derivation of Kepler's laws from his theory of gravity, contained in the paper De motu corporum in gyrum, is read to the Royal Society by Edmund Halley.

* December 10 – Isaac Newton's derivation of Kepler's laws from his theory of gravity, contained in the paper De motu corporum in gyrum, is read to the Royal Society by Edmund Halley.

Newton's tract ' De motu ...', which he sent to Halley in late 1684, derived what are now known as the three laws of Kepler, assuming an inverse square law of force, and generalized the result to conic sections.

Saunderson possessed the friendship of many of the eminent mathematicians of the time, such as Sir Isaac Newton, Edmund Halley, Abraham De Moivre and Roger Cotes.

Although he began a translation, it was Halley who finished it and included it in a 1706 volume with his restoration of De Spatii Sectione.

De motu corporum in gyrum ( Latin )( translated as " On the motion of bodies in an orbit ") is the ( presumed ) title of a manuscript by Isaac Newton sent to Edmond Halley in November 1684.
