Conceiving the line NN' to be that of the nodes at any time, and the earth and lunar orbit to be moving in the direction of the straight arrows, the earth will be on one side of the ecliptic from M2 to M5, and on the other side from M6 to M 1, intersecting it at the nodes.Advertisement
This excess is, however, subject to wide variation, owing to the obliquity of the ecliptic and of the lunar orbit to the equator, and therefore to the horizon.
The other side of the moon is therefore invisible from the earth, but in consequence of the libration about six-tenths of the lunar surface may be seen at one time or another, while the remaining four-tenths are for ever hidden from our view.
This shows that the side of the moon presented to us is held in position as it were by the earth, from which it also follows that the lunar globe is more or less elliptical, the longer axis being directed toward the earth.

He compiled the Hakimite Tables of the planets, and observed at Cairo, in 977 and 978, two solar eclipses which, as being the first recorded with scientific accuracy, 4 were made available in fixing the amount of lunar acceleration.Advertisement
Yet his rationale of the tides in De Motibus Stellae is not only memorable as an astonishing forecast of the principle of reciprocal attraction in the proportion of mass, but for its bold extension to the earth of the lunar sphere of influence.
Gravitation was thus shown to be the sole influence governing the movements of planets and satellites; the figure of the rotating earth was successfully explained by its action on the minuter particles of matter; tides and the precession of the equinoxes proved amenable to reasonings based on the same principle; and it satisfactorily accounted as well for some of the chief lunar and planetary inequalities.
One is the existence of dark and bright regions, irregular in form, on its surface; the other is the complete illumination of the lunar disk when seen as a crescent, a faint light revealing the dark hemisphere.
To an observer on the moon our earth would present a surface more than ten times as large as the moon presents to us, consequently this earth-light is more than ten times brighter than our moonlight, thus enabling the lunar surface to be seen by us.

In the article Calendar (q.v.), that part of chronology is treated which relates to the measurement of time, and the principal methods are explained that have been employed, or are still in use, for adjusting the lunar months of the solar year, as well as the intercalations necessary for regulating the civil year according to the celestial motions.
Euphratean exploration has so far brought to light no traces of ecliptical partition by the moon's diurnal motion, unless, indeed, zodiacal associations be claimed for a set of twenty-eight deprecatory formulae against evil spirits inscribed on a Ninevite tablet.4 The safest general conclusions regarding this disputed subject appear to be that the sieu, distinctively and unvaryingly Chinese, cannot properly be described as divisions of a lunar zodiac, that the nakshatras, though of purely Indian origin, became modified by the successive adoption of Greek and Chinese rectifications and supposed improvements; while the manazil constituted a frankly eclectic system, in which elements from all quarters were combined.
The insurmountable difficulties presented by the lunar theory forced Kepler, after an enormous amount of fruitless labour, to abandon his design of comprehending the whole scheme of the heavens in one great work to be called Hipparchus, and he then threw a portion of his materials into the form of a dialogue intended for the instruction of general readers.
Lastly, in astronomy he is credited by Ptolemy with an explanation of the motion of the planets by a system of epicycles; he also made reseafches in the lunar theory, for which he is said to have been called Epsilon (e).
The Restoration Of The Equinox To Its Former Place In The Year And The Correction Of The Intercalary Period, Were Attended With No Difficulty; But Lilius Had Also To Adapt The Lunar Year To The New Rule Of Intercalation.

The numbers down the left side of the chart represents the mother's lunar age at the time she conceived.
The months across the top of the chart represent the lunar month when the mother conceived.
Part of the chart's use includes converting your age and the month in which you are conceiving from solar months to lunar.
A lunar month is the time it takes to pass from one full moon to the next - roughly 29.5 days.
Your lunar age is also calculated differently, because you are thought to be one year old at the time of your birth according to the Chinese calendar.
To determine your Chinese age, subtract the year in which you were born from the current year (or the year in which you conceived), then add one to the number - this is your lunar age, plus or minus a few days for the shorter month length.
To determine the lunar month, take a look at a Chinese calendar for that year.
Proponents believe that the Chinese lunar birth calendar is about 99 percent accurate.
In addition to the possibility of using a Chinese lunar calendar to predict the sex of a baby once a woman becomes pregnant, some women use the calendar or Chinese birth chart to possibly increase their odds of conceiving a boy or a girl.
The Chinese Lunar Pregnancy Calendar is an ancient document that contains a chart listing which gender a woman will conceive in a given month.
It's based on the lunar calendar, which generally gives women a higher age than the eastern calendar.
For example, a woman who is 34 might be 36 on the lunar chart.
The jury is still out on whether timing intercourse around ovulation or following the Chinese lunar calendar will really increase your chances of having a girl.
Then there's the Chinese Lunar Pregnancy Calendar, which predicts gender based on the mother's lunar age at conception and the month the baby is conceived in.

Whichever system is used, either lunar or solar, all of the Chinese astrologers adhere to the five element theory to assist in creating astrological charts.
The Chinese New Year Day is based on the Chinese lunar calendar, whereas the Chinese Year of the (insert appropriate animal - in 2009 it's the Ox) is based on the Chinese solar calendar.
Before the years were assigned an animal, the twelve-year lunar cycle was governed by the theory of the Twelve Earth Branches.
Unlike Western astrology, traditional Chinese astrology is based on lunar cycles.
In this way, one is able to find a little bit of information on everything from palmistry to the lunar cycles.
For example, under the heading Lunar Phases, you'll find all the lunar phases listed and a few words on timing and the moon, but there is no further information about how the moon you're born under affects your personality.
One important fact to keep in mind is that the Chinese lunar new year occurs somewhere between January 21 and February 21, not on January first as found in the Western solar calendar.
Chinese astrology is based not on the solar calendar like western astrology, but on the lunar calendar.
Since it takes twelve years for a complete lunar cycle, each of the twelve zodiac signs represents one year, instead of a constellation as in western astrology.
That's because Chinese astrology is based on the lunar calendar, not the solar calendar which western astrology uses.
Each lunar calendar year is governed by an element just as your zodiac sign is governed by a specific element.

From the same period also they have employed, in the adjustment of their solar and lunar years, a period of nineteen years, twelve of which are common, containing twelve lunations each, and the remaining seven intercalary, containing thirteen lunations.
Acquaintance with foreign systems of twenty-eight lunar divisions tended doubtless to fix its position, which remained, nevertheless, always equivocal.
For genethliacal purposes the signs were divided into six solar and six lunar, the former counted onward from Leo, the " house " of the sun, the latter backward from the moon's domicile in Cancer.
The solar day, the solar year, and the lunar month, or lunation, may therefore be called the natural divisions of time.
In Order To Put An End To The Disorders Arising From The Negligence Or Ignorance Of The Pontiffs, Caesar Abolished The Use Of The Lunar Year And The Intercalary Month, And Regulated The Civil Year Entirely By The Sun.
The Lunar Year, Consisting Of Twelve Lunar Months, Contains Only 354 Days; Its Commencement Consequently Anticipates That Of The Solar Year By Eleven Days, And Passes Through The Whole Circle Of The Seasons In About Thirty Four Lunar Years.
The Lunar Year, Therefore, Contained 354 Days, Falling Short Of The Exact Time Of Twelve Lunations By About 8.8 Hours.
The First Expedient Adopted To Reconcile The Lunar And Solar Years Seems To Have Been The Addition Of A Month Of Thirty Days To Every Second Year.
Two Lunar Years Would Thus Contain 25 Months, Or 738 Days, While Two Solar Years, Of 3654 Days Each, Contain 7302 Days.V The `, Difference Of 72 Days Was Still Too Great To Escape Observation; It Was Accordingly Proposed By Cleostratus Of Tenedos, Who Flourished Shortly After The Time Of Thales, To Omit The Biennary Intercalation Every Eighth Year.
In Fact, The 72 Days By Which Two Lunar Years Exceeded Two Solar Years, Amounted To Thirty Days, Or A Full Month, In Eight Years.
The Jews Celebrated Their Passover On The 14Th Day Of The First Month, That Is To Say, The Lunar Month Of Which The Fourteenth Day Either Falls On, Or Next Follows, The Day Of The Vernal Equinox.
The Observance Of This Rule Renders It Necessary To Reconcile Three Periods Which Have No Common Measure, Namely, The Week, The Lunar Month, And The Solar Year; And As This Can Only Be Done Approximately, And Within Certain Limits, The Determination Of Easter Is An Affair Of Considerable Nicety And Complication.
In connecting the lunar month with the solar year, the framers of the ecclesiastical calendar adopted the period of Meton, or lunar cycle, which they supposed to be exact.
The lunations are supposed to consist of twenty-nine and thirty days alternately, or the lunar year of 354 days; and in order to make up nineteen solar years, six embolismic or intercalary months, of thirty days each, are introduced in the course of the cycle, and one of twenty-nine days is added at the end.
This gives 19 X354+6 X 30429 = 6 935 days, to be distributed among 235 lunar months.
But every leap year one day must be added to the lunar month in which the 29th of February is included.
The reason is that the sum of the solar and lunar inequalities, which are compensated in the whole period, may amount in certain cases to io, and thereby cause the new moon to arrive on the second day before or after its mean time.
The cycle of the sun brings back the days of the month to the same day of the week; the lunar cycle restores the new moons to the same day of the month; therefore 28 X 19 = 53 2 years, includes all the variations in respect of the new moons and the dominical letters, and is consequently a period after which the new moons again occur on the same day of the month and the same day of the week.
Besides the solar and lunar cycles, there is a third of 15 years, called the cycle of indiction, frequently employed in the computations of chronologists.
By means of the lunar cycle the new moons of the calendar were indicated before the Reformation.
We have already seen that the year 1 of the era had Io for its number in the solar cycle, 2 in the lunar cycle, and 4 in the cycle of indiction; the question is therefore to find a number such, that Iv.
The Lunar Cycle Contained 6 939 Days 18 Hours, Whereas The Exact Time Of 235 Lunations, As We Have Already Seen, Is 235X29.530588= 6939 Days 16 Hours 31 Minutes.
Another Addition Of Eleven Gives Thirty Three For The Epact Of The Fourth Year; But In Consequence Of The Insertion Of The Intercalary Month In Each Third Year Of The Lunar Cycle, This Epact Is Reduced To Three.
This Method Of Forming The Epacts Might Have Been Continued Indefinitely If The Julian Intercalation Had Been Followed Without Correction, And The Cycle Been Perfectly Exact; But As Neither Of These Suppositions Is True, Two Equations Or Corrections Must Be Applied, One Depending On The Error Of The Julian Year, Which Is Called The Solar Equation; The Other On The Error Of The Lunar Cycle, Which Is Called The Lunar Equation.
Thus The Epacts I 1, 22, 3, 14, &C., Become 10, 21, 2, 13, &C. On The Other Hand, When The Time By Which The New Moons Anticipate The Lunar Cycle Amounts To A Whole Day, Which, As We Have Seen, It Does In 308 Years, The New Moons Will Arrive One Day Earlier, And The Epacts Must Consequently Be Increased By Unity.
Thus The Epacts 11, 22, 3, 14, &C., In Consequence Of The Lunar Equation, Become 12, 23, 4, 15, &C. In Order To Preserve The Uniformity Of The Calendar, The Epacts Are Changed Only At The Commencement Of A Century; The Correction Of The Error Of The Lunar Cycle Is Therefore Made At The End Of 300 Years.
The Years In Which The Solar Equation Occurs, Counting From The Reformation, Are 1700, 1800, 1900, 2100, 2200, 2300, 2500, &C. Those In Which The Lunar Equation Occurs Are 1800, 2100, 2400, 2700, 3000, 3300, 3600, 3900, After Which, 4300, 4600 And So On.
In Consequence Of The Solar And Lunar Equations, It Is Evident That The Epact Or Moon'S Age At The Beginning Of The Year, Must, In The Course Of Centuries, Have All Different Values From One To Thirty Inclusive, Corresponding To The Days In A Full Lunar Month.
The Second Column, Corresponding To The Following Year In The Lunar Cycle, Must Have All Its Epacts Augmented By 11; The Lowest Number, Therefore, In The Column Is 12, Then 13, 14, 15 And So On.
In That Year The Omission Of The Intercalary Day Rendered It Necessary To Diminish The Epacts By Unity, Or To Pass To The Line C. In 1800 The Solar Equation Again Occurred, In Consequence Of Which It Was Necessary To Descend One Line To Have The Epacts Diminished By Unity; But In This Year The Lunar Equation Also Occurred, The Anticipation Of The New Moons Having Amounted To A Day; The New Moons Accordingly Happened A Day Earlier, Which Rendered It Necessary To Take The Epacts In The Next Higher Line.
When The Solar Equation Occurs Alone, The Line Of Epacts Is Changed To The Next Lower In The Table; When The Lunar Equation Occurs Alone, The Line Is Changed To The Next Higher; When Both Equations Occur Together, No Change Takes Place.
The Reason For Doubling The 25 Was To Prevent The New Moons From Being Indicated In The Calendar As Happening Twice .On The Same Day In The Course Of The Lunar Cycle, A Thing Which Actually Cannot Take Place.
When The Golden Number Is 19, That Is To Say, In The Last Year Of The Lunar Cycle, The Supplementary Month Contains Only 29 Days.
In Order To Investigate A Formula For The Epact, Let Us Make E=The True Epact Of The Given Year; J =The Julian Epact, That Is To Say, The Number The Epact Would Have Been If The Julian Year Had Been Still In Use And The Lunar Cycle Had Been Exact;, S =The Correction Depending On The Solar Year; M =The Correction Depending On The Lunar Cycle; Then The Equation Of The Epact Will Be E=J S M; So That E Will Be Known When The Numbers J, S, And M Are Determined.
We Have Therefore S= (C 16) (C 16) 4 With Regard To The Lunar Equation M, We Have Already Stated That In The Gregorian Calendar The Epacts Are Increased By Unity At The End Of Every Period Of 300 Years Seven Times Successively, And Then The Increase Takes Place Once At The End Of 400 Years.
Had The Anticipation Of The New Moons Been Taken, As It Ought To Have Been, At One Day In 308 Years Instead Of 3121, The Lunar Equation Would Have Occurred Only Twelve Times In 3700 Years, Or Eleven Times Successively At The End Of 300 Years, And Then At The End Of 400.
In Those Years In Which The Line Of Epacts Is Changed In The Gregorian Calendar, The Golden Numbers Are Removed To Different Days, And Of Course A New Table Is Required Whenever The Solar Or Lunar Equation Occurs.
The Year Is Luni Solar, And, According As It Is Ordinary Or Embolismic, Consists Of Twelve Or Thirteen Lunar Months, Each Of Which Has 29 Or 30 Days.
The Years Of The Hegira Are Purely Lunar, And Always Consist Of Twelve Lunar Months, Commencing With The Approximate New Moon, Without Any Intercalation To Keep Them To The Same Season With Respect To The Sun, So That They Retrograde Through All The Seasons In About 321 Years.
Appended to the London edition of the solar and lunar tables are two short tracts - the one on determining longitude by lunar distances, together with a description of the repeating circle (invented by Mayer in 1752), the other on a formula for atmospheric refraction, which applies a remarkably accurate correction for temperature.
The humerus often has a foramen (entepicondylar) on the inner side of its lower end; the tibia and fibula may be separate or united; but the scaphoid and lunar of the carpus are also united, while the centrale is free.
In the carpus the scaphoid and lunar are welded, but the centrale remains distinct.
In the Bathyergoidea the scaphoid and lunar of the carpus are separate, the tibia and fibula united and the clavicles normal.
The tibia and fibula are separate, but the scaphoid and lunar are united, and the clavicles are generally incomplete.
As clerk (1795) and then as supercargo (1796, 1798, 1799) he made four long voyages; and, being an excellent navigator, he afterwards (1802) commanded a vessel, instructing his crews in lunar and other observations.

The lunar theory connects it with the disappearance of the moon at the time of change or during an eclipse.
It is suggested that this is due to the fact that, at the time of the adoption of the oriental goddess, the Greeks already possessed lunar divinities in Hecate, Selene, Artemis.
It has been explained by reference to the lunar character of the goddess, but more probably signifies " she whose seat is in heaven," whence she exercises her sway over the whole world - earth, sea, and air alike.
It derived its name, according to the etymology of the Pundits, from a prince of the Mahabharata, to whose portion it fell on the primitive partition of the country among the Lunar race of Delhi.
Brown's lunar theory would imply a parallax 8.778".
Instead of confining himself, as before, to the fruitless integration of three differential equations of the second degree, which are furnished by mathematical principles, he reduced them to the three co-ordinates which determine the place of the moon; and he divided into classes all the inequalities of that planet, as far as they depend either on the elongation of the sun and moon, or upon the eccentricity, or the parallax, or the inclination of the lunar orbit.
The treatise on "Mechanics" in Lardner's Cyclopaedia was partly written by him; and his interest in more purely astronomical questions was evidenced by two communications to the Astronomical Society's Memoirs for 1831-1833 - the one on an observation of Saturn's outer ring, the other on a method of determining longitude by means of lunar eclipses.
The system of intercalation in the lunar calendar of the heathen Arabs was designed to secure that the feast should always fall at the time when the hides, fruits and other merchandise were ready for market, 4 and the Meccans, who knew how to attract the Bedouins by hospitality, bought up these wares in exchange for imported goods, and so became the leaders of the international trade of Arabia.
The grateful Byzantines erected a statue to "torch-bearing" Hecate, and adopted the lunar crescent as the badge of the city.

The first volume contains his previously published writings; the second those left in manuscript, including the substance of his lectures on the Lunar Theory.
Sir Isaac Newton, who depended for the perfecting of his lunar theory upon "places of the moon" reluctantly doled out from Greenwich, led the movement for immediate communication; whence arose much ill-feeling between him and Flamsteed.
They were, on the other hand, probably acquainted, a couple of millenniums before Meton gave it his name, with the nineteen-year cycle, by which solar and lunar years were harmonized; 1 they immemorially made observations in the meridian; regulated time by water-clocks, and used measuring instruments of the nature of armillary spheres and quadrants.
In the Ephemerides published year by year, the times of new moon were given, together with the calculated intervals to the first visibility of the crescent, from which the beginning of each month was reckoned; the dates and circumstances of solar and lunar eclipses were predicted; and due information was supplied as to the forthcoming heliacal risings and settings, conjunctions and oppositions of the planets.
Kugler 7 that the various periods underlying their lunar predictions were identical with those heretofore believed to have been independently arrived at by Hipparchus, who accordingly must be held to have borrowed from Chaldaea the lengths of the synodic, sidereal, anomalistic and draconitic months.
He, nevertheless, used telescopes to good purpose in his studies of lunar topography, and his designations for the chief mountainchains and " seas " of the moon have never been superseded.
The general trend of lunar investigation has been against the view that there is any resemblance between the surfaces of the moon and of the earth, except in the general features already mentioned.
The period of revolution, or the lunar month, depends upon the point to which the revolution is referred.
This Hipparchus was enabled to do by lunar eclipses.
We may conclude the ancient history of the lunar theory by saying that the only real progress from Hipparchus to Newton consisted in the more exact determination of the mean motions of the moon, its perigee and its line of nodes, and in the discovery of three inequalities, the representation of which required geometrical constructions increasing in complexity with every step.
The modern lunar theory began with Newton, and consists in determining the motion of the moon deductively from the theory of gravitation.
But the great founder of celestial mechanics employed a geometrical method, ill-adapted to lead to the desired result; and hence his efforts to construct a lunar theory are of more interest as illustrations of his wonderful power and correctness in mathematical reasoning than as germs of new methods of research.
During the twenty years following he devoted a large part of his energies to the numerical computation of the lunar inequalities, the redetermination of the elements of motion, and the preparation of new tables for computing the moon's position.
Thus a new branch of the lunar theory was suggested - the determination by theory of the effect of planetary action.
It was therefore surprising when, in 1877, Simon Newcomb found, by a study of the lunar eclipses handed down by Ptolemy and those observed by the Arabians - data much more reliable than the vague accounts of ancient solar eclipses - that the actual apparent acceleration was only about 8.3".
His first recorded observation was made before he was sixteen, and the presentation of an elaborate lunar map procured for him admission to the Academy, on the 21st of April 1736, at the early age of twenty.

See Cornhill Magazine, " How the Stars got their Names " (1882, p. 35), and " Some Solar and Lunar Myths " (1882, P. 440); Max Muller, Selected Essays, i.
In 1838 he published a revision of the lunar theory, entitled Fundamenta nova investigationis, &c., and the improved Tables of the Moon based upon it were printed in 1857, at the expense of the British government, their merit being further recognized by a grant of 1000, and by their immediate adoption in the Nautical Almanac, and other Ephemerides.
A theoretical discussion of the disturbances embodied in them (still familiarly known to lunar experts as the Darlegung) appeared in the Abhandlungen of the Saxon Academy of Sciences in 1862-1864.

It was thus an effective compromise between the solar year and the lunar month, and contrasts very favorably with the intricate and clumsy years of other ancient systems. The leap-year of the Julian and Gregorian calendars confers the immense benefit of a fixed correspondence to the seasons which the Egyptian year did not possess, but the uniform length of the Egyptian months is enviable even now.
Aristarchus of Samos observed at Alexandria 280-264 B.C. His treatise on the magnitudes and distances of the sun and moon, edited by John Wallis in 1688, describes a theoretically valid method for determining the relative distances of the sun and moon by measuring the angle between their centres when half the lunar disk is illuminated; but the time of dichotomy being widely indeterminate, no useful result was thus obtainable.

In none of the existing, and in but few of the extinct types, are collar-bones, or clavicles, developed; and the scaphoid and lunar bones of the carpus are separate.
His method of estimating the relative lunar and solar distances is geometrically correct, though the instrumental means at his command rendered his data erroneous.

Although it did not enter into the calendar of the Greeks, and was not introduced at Rome till after the reign of Theodosius, it has been employed from time immemorial in almost all eastern countries; and as it forms neither an aliquot part of the year nor of the lunar month, those who reject the Mosaic recital will be at a loss, as Delambre remarks, to assign it to an origin having much semblance of probability.
But in the course of a few years the accumulated difference between the solar year and twelve lunar months would become considerable, and have the effect of transporting the commencement of the year to a different season.
The synodical revolution of the moon laid down the lines of the solar, its sidereal revolution those of the lunar zodiac. The first was a circlet of " full moons "; the second marked the diurnal stages of the lunar progress round the sky, from and back again to any selected star.
Relationship of a more intimate kind connects the Hindu lunar mansions with those of the Arabs and Chinese.
Thus Mercury, as the planet nearest the sun, obtained Virgo, the sign adjacent to Leo, with the corresponding lunar house in Gemini; Venus had Libra (solar) and Taurus (lunar); and so for the rest.

But in the early ages of the world, when mankind were chiefly engaged in rural occupations, the phases of the moon must have been objects of great attention and interest, - hence the month, and the practice adopted by many nations of reckoning time by the motions of the moon, as well as the still more general practice of combining lunar with solar periods.
The Mongolian peoples not only count their lunar months by these signs, but they reckon the successive days by them, rat-day, bull-day, tiger-day, &c., and also, by combining the twelve signs in rotation with the elements, they obtain a means of marking each year in the sixty-year cycle, as the woodrat year, the fire-tiger year, &c. This method is highly artificial, and the reappearance of its principle in the Mexican and Central American calendar is suggestive of importation from Asia.
