Kolokolo Bird Blog Archive What Easter lamb is no common point of Aries?
Today my collection at the Academy of Uczniowska lesson that for me you would not expect: a bit of religion, ancient abstract lights history, a lot of astronomy and a little geography.
Topics covered: Easter and Passover, solar and lunar calendars, the Jewish calendar, the legacy of the Babylonian Jewish calendar, constellations on the ecliptic and zodiac, equinox and change the length of the day, I and II Kepler's law, the precession abstract lights of the equinoxes, lunar and solar cycles abstract lights - a cycle of Meton, month synodic, sidereal and dragon, atmospheric refraction and conditions of observation, repeatability eclipses, Gaussian algorithm for determining the date of Easter, the use of different calendars in civilian life, Christianity and Judaism.
Teaching aids: - globe; - Lamp (the sun); - Orange (Moon); - Sugar lamb (Aries), useful also suitably evocative Pisces abstract lights and Taurus. - Map of the sky (SkyChart 3.6 - a free program for Windows, Mac and Linux); - HORIZONS - Internet service ephemeris JPL-NASA; - Geographical atlas (GoogleEarth); - Old Testament; - WikiPedia.
Lecture, discussion, search the Wiki, the Old Testament and ephemeris: Christian churches use to determine the cycle of the liturgical abstract lights year solar calendar. Easter (and related holidays, as the post or Corpus Christi), however, are determined by the lunar calendar, almost identical to the Jewish calendar. To search in the house (or interrogate a priest, preferably Orthodox): where is the deviation? Why anniversary of the birth of Jesus is celebrated according to the solar cycle, and the anniversary of the resurrection of the moon?
Christian Easter should fall at the same time as the Jewish Passover. In the Middle Ages, was calculated according to the same rules that applied Jews, but these rules were later in a little different way formal (Gregorian abstract lights calendar is more accurate than the Jewish, and this in turn from Julian) and now about once every five years, it happens that Western Easter is a week before Passover. A lasting a week of Passover begins on the fifteenth day of the month of Nisan.
The Jewish day begins at sunset. A new month starts when the sky can be seen for the first time after the new moon the moon. Watch the entire month with the help of the globe, the lamp (the Sun) and orange (Moon) and the sky map. We note that the route passes the Moon during the month synodycznego, sidereal and the dragon. We notice subtle changes between successive months: declination ecliptic Moon, elliptic orbits of both the Moon around the Earth and the Earth around the Sun. We do drawings with exaggerated pulling these ellipses. With the help of the ephemeris (servicing Horizon) calculate with precision-second moments of the new moon. We discuss the observing conditions (clear sky background, atmospheric abstract lights refraction): how far (in terms of angle) Moon must be from the Sun, so we can observe it in the west? What shape is twirl Moon, depending on the latitude of the observer (Jerusalem), the seasons and the declination of the Moon? So we have: 15 Nisan (and every other month) is always abstract lights right after the full moon. Just as Christian abstract lights (Western, Eastern Orthodoxy tends exceptions here) Easter attributable to the first Sunday after the first full after the spring equinox. Question: when it begins to Nisan?
A year is 12 months, every after 29 or 30 days. This year would have been too short by about 11 days compared with the solar year - every few years is therefore a leap year, with an additional month. This extra month is added if necessary, two months before Nisan. In the Old Testament was based on observations, but ever since late antiquity Jews use here Meton cycle (previously known Babylonians) 19 solar years is with pretty good accuracy lunar 235 months. With the help of maps of the sky we see the appearance of the sky by jumping after exactly 19 years. With the ephemeris look like the sky looked at intervals of 380 years (20 cycles of Meton). Jewish year begins in the fall and has 12 months to change the 29 - and 30-day. In 7 years of each set 19 adds an additional 30-day month. In addition, two months alter the length of time (from 29 to 30 or from 30 to 29) for reasons abstract lights primarily liturgical, but also to compensate for the average duration abstract lights of a month to month synodycznego. As a result, the beginnings of months in the years to move compared to the astronomical date (and the Gregorian calendar). About what? Let's count and see a map of the sky.
We looked already on the map and ephemeris for minor discrepancy between the cycle of Meton, and the actual length of the year. Let's, as long as the Jewish calendar were leaving in relation to the astronomical year - that is, how the average for the entire 19-year cycle of the date of paddles
