grnth

inaka banaya hua 'mahasiddhant grnth' jyotish siddhant ka achchha grnth hai. aryabhat dvitiy ne bhi apana samay kahin nahin likha hai.

samay

daktar sinh aur datt ka mat hai [1] ki ye 950 ee. ke lagabhag the, jo shak kal 872 hota hai. dikshit lagabhag 875 shak kahate hain. aryabhat dvitiy brahmagupt ke bad hue hai, kyonki brahmagupt ne aryabhatt ki jin baton ka khndan kiya hai ve 'aryabhatiy' se milati hain, 'mahasiddhant' se nahin. mahasiddhant se to prakat hota hai ki brahmagupt ne aryabhatt ki jin-jin baton ka khndan kiya hai ve isamen sudhar di gee hain. 'kuttak ki vidhi' men bhi aryabhatt pratham, bhaskar pratham tatha bahmagupt ki vidhiyon se kuchh unnati dikhaee padati hai. isalie isamen sndeh nahin ki aryabhat dvitiy brahmagupt ke bad hue hain.

brahmagupt aur lall ne ayan chalan ke snbndh men kaee charcha nahin ki hai, parntu aryabhat dvitiy ne is par bahut vichar kiya hai. apane grnth 'madhyamadhyay' ke shlok 11- 12 men inhonne 'ayan bindu' ko ek grah manakar isake 'kalpabhagan' ki snkhya 5,78,159 likhi hai jisase ayan bindu ki varshik gati 173 'vikala' hoti hai jo bahut hi ashuddh hai. spashtadhikar men spasht ayanansh janane ke lie jo riti bataee gee hai usase prakat hota hai ki inake anusar ayanansh 24 ansh se adhik nahin ho sakata aur ayan ki varshik gati bhi sada ek si nahin rahati. kabhi ghatate-ghatate shoony ho jati hai aur kabhi badhate-badhate 173 vikala ho jati hai. isase siddh hota hai ki aryabhat dvitiy ka samay vah tha jab ayanagati ke snbndh men hamare siddhanton ko koee nishchay nahin hua tha.

  • munjal ke 'laghumanas' men ayan chalan ke snbndh men spasht ullekh hai, jisake anusar ek kalp men ayan bhagan 1,99,669 hota hai, jo varsh men 59.9 vikala hota hai. munjal ka samay 854 shak ya 932 eesvi hai, isalie aryabhat ka samay isase bhi kuchh pahale hona chahie. inaka samay 800 shak ke lagabhag hona chahie.
