Two namesakes who left indelible mark in their own right: One is Bhaskaracharya and another is Bhaskararaya.
Bhaskaracharya (Bhaskara II) was born in a family of scholars, mathematicians and astronomers, was the leader of a cosmic observatory at Ujjain, the main mathematical centre of ancient India. Bhāskara and his works represent a significant contribution to mathematical and astronomical knowledge in the 12th century. He has been called the greatest mathematician of medieval India. His main work Siddhānta-Śiromani, for “Crown of Treatises” is divided into four parts called Līlāvatī, Bījagaṇita, Grahagaṇita and Golādhyāya, which are also sometimes considered four independent works. These four sections deal with arithmetic, algebra, mathematics of the planets, and spheres respectively. He also wrote another treatise named Karaṇā Kautūhala.
Bhāskara’s work on calculus predates Newton and Leibniz by over half a millennium. He is particularly known in the discovery of the principles of differential calculus and its application to astronomical problems and computations. While Newton and Leibniz have been credited with differential and integral calculus, there is strong evidence to suggest that Bhāskara was a pioneer in some of the principles of differential calculus. He was perhaps the first to conceive the differential coefficient and differential calculus. His book on arithmetic is the source of interesting legends that assert that it was written for his daughter, Lilavati.
There is an interesting anecdote- Bhaskara II studied Lilavati’s horoscope and predicted that she would remain both childless and unmarried. To avoid this fate, he ascertained an auspicious moment for his daughter’s wedding and to alert his daughter at the correct time, he placed a cup with a small hole at the bottom of a vessel filled with water, arranged so that the cup would sink at the beginning of the propitious hour. He put the device in a room with a warning to Lilavati to not go near it. In her curiosity though, she went to look at the device and a pearl from her bridal dress accidentally dropped into it, thus upsetting it. The auspicious moment for the wedding thus passed unnoticed leaving a devastated Bhaskara II. It is then that he promised his daughter to write a book in her name, one that would remain till the end of time as a good name is akin to a second life. Lilavati, later emulated her father and specialised in the same subjects.
The other great giant is the 17th century (1690–1785) Bhaskararaya. He is widely considered an authority on all questions pertaining to the worship of the Mother Goddess in Shaktism/Hinduism. He was born in Hyderabad, Telangana, was welcomed by king Serfoji II of Bhonsle dynasty in South India, and thereupon he settled in Tamil Nadu.
Bhaskararaya is the attributed author of more than 40 and range from Vedanta to poems of devotion and from Indian logic and Sanskrit grammar to the studies of Tantra. Several of his texts are considered particularly notable to the Shaktism tradition, one focussed on the Mother Goddess:
• Commentary on Tripura Upanishad and Bhavana Upanishad
• Commentary on Devi Mahatmya, titled Guptavati. Bhaskararaya, in his Guptavati, offers comments on 224 out of the 579 verses of the Devi Mahatmya.
• Varivasya Rahasya, is a commentary on Sri Vidya mantra and worship. The Varivasya Rahasya contains 167 ślokas numbered consecutively. It has an accompanying commentary entitled “Prakāśa“, also by Bhaskararaya.
• Setubandha is a technical treatise on Tantric practice. It is his magnum opus. It is a commentary on a portion of the Vāmakeśvara-tantra dealing with the external and internal worship of Tripura Sundari.
• “Soubhāgyabhāskara“is a commentary (bhāsya) on Lalita Sahasranama.
• His Khadyota (“Firefly”) commentary on the Ganesha Sahasranama is considered authoritative by Ganapatya.
There is another interesting anecdote attributed to this Bhaskararaaya…
In Rameswaram jyotirlinga temple, many people argued that main Lingam of the temple was not made of sand and also said that if Lingam was made of sand it would have been dissolved while anointing the Lord.
During that time, Bhaskararaaya made a Lingam out of salt and anointed it. But the Lingam did not dissolve. He said that if the Lingam made by him who worship Devi Parvati did not dissolve, then it is of no wonder that the Lingam made by the wife of Lord Vishnu is not dissolved yet. The salt Lingam made by him is present even now behind the main Lingam of the temple. Even after many years, the salt Lingam also has not yet dissolved like the main ‘sand’ lingam!

The stories attributed to these two Indian giants are indeed very interesting, though curious to the scientifically oriented.
