A book by Dr. Venketeswara R. Pai and co-authors on Bhaskaracharya's Siddhāntaśiromaṇi was released by the Hon'ble Union Minister for External Affairs, Dr. S. Jaishankar at the India International Centre, New Delhi, during a conference on Mathematical Practices in South Asia.
Titled "Bhāskarācārya's Siddhāntaśiromaṇi – Grahagaṇita with the Vāsanābhāṣya", this book is a translation, from Sanskrit to English, of Siddhantasiromani composed in 1150 CE by the mathematician-astronomer Bhaskaracharya in Sanskrit. Grahaganita is one section of the original Siddhantasiromani with 460 verses and Vāsanābhāṣya is a commentary by Bhaskaracharya included in the same book.
The present book, by Dr. Pai and co-authors, translates both of these sections into English along with explanatory notes. Furthermore, this is the first time Vāsanābhāṣya is being translated into English, making it accessible to a wider audience.
Dr. Pai is a faculty member at the Humanities and Social Sciences Department of IISER Pune and is working on the history of astronomy in the Indian subcontinent. He co-authored the present book along with M. S. Sriram, Sita Sundar Ram. The book has been published in two volumes as part of the Culture and History of Mathematics (Vol 13) series by the Hindustan Book Agency, and is going to be published by Springer.
