Indian and Islamic calendars
Brahmagupta is still playing an important role in the existing field of astronomy he calculated the positions of heavenly bodies ,he also concluded their rising and setting time frames and as to why the shape of the moon varies with the passing time not only this he also derived the true longitudes between different planets and between sun and moon ,the explanation of solar and lunar eclipses was also an effort by Brahmagupta in his book Brahmasphutasiddhanta (chapter 7). Al-Biruni, the famous Arabic scholar, translated Brahmasphutasiddhanta into Arabic as Sindhind. We are all aware of the fact that Indian and Islamic calendars are based on the positions of sun and moon and it was due to sheer genius of Brahamagupta, which framed the basic foundation of the Indian and Islamic calendars.
BRAHMAGUPTA'S calenders
Brahmagupta's work
Brahmagupta taught us basic mathematics
Brahmagupta describes about Zero as one of the numerals which stood for meaning nothing. He also elaborates as to how integers positive and negative consequence when played with zero.
A general view of Brahmagupta’s enormous work
A brief review of his genuine intelligent work will prove why he is called the mentor of numbers and astronomy.
The gravitational pull of Brahmagupta and Newton
The decision should be left on the people and the world to be decided, which gravitational pull is attracting them more Newton or Brahamagupta’s.
Significance of Brahmagupta discoveries in modern world
If someone questions about the significance of Brahamgupta’s work it will be like questioning the existence of man itself.
Cultural and time travel of Brahmagupta and his concepts
His simple formulae about the cyclic quadrilateral in a circle have become more complex and easier with the help of computers who bargain the millions of calculations in a wink of an eye.
