Dzuwa ndi mwezi yamakedzana

Pankhaniyi, podziwa zinthu zakuthambo kuwerengetsera malo a dzuwa nthawi iliyonse, inu akhoza kungoyankha, mothandizidwa ndi miyezo izi kutalika kwa dzuwa, kudziwa udindo wa pachimake imene nthawi iliyonse mukufuna; kuti m'pofunika yekha kukhala chida mungathe kuyeza ndi kuganizira kayendedwe ka mfundo pachimake kaya kuzungulira kwa dziko padziko nguli, mwachitsanzo. e. kuthetsa mphamvu ya kasinthasintha akuoneka wa lakumwamba svoda.Solntsa ndi Moon mu Drevnem World ...

Amadziwika kuti udindo wa matupi akumwamba, komanso pachimake ndi malo osiyana a dziko anatsimikiza pa dera lakumwamba m'njira yofanana ndi mtima cha mmene mfundo osiyanasiyana a dziko lapansi, ndiwo yamphamvu ndi longitude; ufuluwo. The meridian loyamba longitude amene amaonedwa (pa equator), ndi amene umadutsa mzati wa dziko ndi mfundo ya March vernal. Ngakhale kalelo anthu ankadziwa kuti mwezi ndi pa chizindikiro cha m'nyenyezi, ndipo chizindikiro chirichonse ndi nthawi zina, ndiye apita sleduyushy m'nyenyezi chizindikiro, Mwezi mu Aries, Moon mu Cancer ....

Equatorial kumpoto kwa mfundo iliyonse mu mlengalenga imatengedwa kukhala laling'ono Arc mtunda kuchokera equator m'mwamba, pamene kumpoto Hrs chilichonse "kufika pamwamba lapansi imatengedwa mbali pakati pa chitsogozo cha mtunda phompho ndi ndege kufanana kwa ndege ya dziko.

Choncho anapezazo pamalo dzuwa zoyenda, ndi zotheka pa nthawi iliyonse kudziwa longitude yamphamvu ndi kumpoto kwa dzuwa; choncho kubala zatchulidwazi awiri chingwe okwera dzuwa ntchito chronometer, kuwonetsa kusintha yunifolomu kwathunthu mu kunyanja longitude pachimake mu malo kuonerera, n'zotheka kudziwa longitude yamphamvu ndipo derali lili pa pachimake kuti zimene mukufuna tsopano.

Koma pamaziko a zimene takambiranazi, pachimake kunyanja mu malo chidwi ndi wina kuposa ufulu wa mfundoyo. Equatorial chomwecho longitude pachimake sichinafike yekha amaona kuti tipeze malo a padziko lapansi, kuyambira amaona osati kuchokera meridian iliyonse pa dziko lapansi, ndi kwa tatchulawa meridian woyamba wa dera lakumwamba; zokhudza pachimake meridian mosalekeza atasintha ake chifukwa kasinthasintha wa dziko lapansi.
