aryabhatt dvitiy ganit aur jyotish donoan vishayoan ke achary the.
- granth
inaka banaya hua 'mahasiddhaant granth' jyotish siddhaant ka achchha granth hai. aryabhat dvitiy ne bhi apana samay kahian nahian likha hai.
- samay
daktar sianh aur datt ka mat hai [1] ki ye 950 ee. ke lagabhag the, jo shak kal 872 hota hai. dikshit lagabhag 875 shak kahate haian. aryabhat dvitiy brahmagupt ke bad hue hai, kyoanki brahmagupt ne aryabhatt ki jin batoan ka khandan kiya hai ve 'aryabhatiy' se milati haian, 'mahasiddhaant' se nahian. mahasiddhaant se to prakat hota hai ki brahmagupt ne aryabhatt ki jin-jin batoan ka khandan kiya hai ve isamean sudhar di gee haian. 'kuttak ki vidhi' mean bhi aryabhatt pratham, bhaskar pratham tatha bahmagupt ki vidhiyoan se kuchh unnati dikhaee p dati hai. isalie isamean sandeh nahian ki aryabhat dvitiy brahmagupt ke bad hue haian.
brahmagupt aur lall ne ayan chalan ke sanbandh mean kaee charcha nahian ki hai, parantu aryabhat dvitiy ne is par bahut vichar kiya hai. apane granth 'madhyamadhyay' ke shlok 11- 12 mean inhoanne 'ayan biandu' ko ek grah manakar isake 'kalpabhagan' ki sankhya 5,78,159 likhi hai jisase ayan biandu ki varshik gati 173 'vikala' hoti hai jo bahut hi ashuddh hai. spashtadhikar mean spasht ayanaansh janane ke lie jo riti bataee gee hai usase prakat hota hai ki inake anusar ayanaansh 24 aansh se adhik nahian ho sakata aur ayan ki varshik gati bhi sada ek si nahian 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 sanbandh mean hamare siddhaantoan ko koee nishchay nahian hua tha.
- muanjal ke 'laghumanas' mean ayan chalan ke sanbandh mean spasht ullekh hai, jisake anusar ek kalp mean ayan bhagan 1,99,669 hota hai, jo varsh mean 59.9 vikala hota hai. muanjal 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.
