The mathematical part of the Aryabhatiya covers arithmetic, algebra, plane trigonometry, spherical trigonometry, fractions, quadratic equations, sums-of-power series, and a table of sines.<\/span>\r\n<ul>\r\n\t<li><b>Khagol-shastra: <\/b><span style=\"font-weight: 400\">The part of Aryabhatiya which deals with astronomy is known as Khagol-shastra. Khagol was the famous astronomical observatory at Nalanda, where Aryabhata studied.<\/span><\/li>\r\n<\/ul>\r\n<\/li>\r\n\t<li style=\"font-weight: 400\"><b>Arya Siddhanta: <\/b><span style=\"font-weight: 400\">It deals with astronomical calculations, and it contains a description of several astronomical instruments, like<\/span>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The gnomon (shanku-yantra)<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">A shadow instrument (chhaya-yantra)<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Semicircular and circular angle-measuring devices (dhanur-yantra\/ chakra-yantra)<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">A cylindrical stick called the yastiyantra<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">An umbrella-shaped device (chhatra-yantra)<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Bow-shaped as well as cylindrical water clocks<\/span><\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n<h3><span style=\"font-weight: 400\">Aryabhata Contribution to Astronomy<\/span><\/h3>\r\n<p><span style=\"font-weight: 400\">Aryabhata made remarkable contributions to ancient astronomy. His system of astronomy was called the audAyaka system (days are reckoned from uday, dawn at Lanka, equator).<\/span><\/p>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><b>Principle of Rotation: <\/b><span style=\"font-weight: 400\">The discovery, recorded in the Aryabhatiya, that the Earth rotates around its own axis from west to east is significant.<\/span>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Aryabhata also declared that the Earth rotates around the Sun and the moon moves around the Earth.<\/span><\/li>\r\n<\/ul>\r\n<\/li>\r\n\t<li style=\"font-weight: 400\"><b>Eclipses: <\/b><span style=\"font-weight: 400\">In Aryabhatiya, he introduces the idea of shadows, cast by and falling on Earth, moon, and planets, and states that the lunar eclipse is caused by the entering of the moon into the Earth's shadow.<\/span>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Aryabhata gives formulas for the length and diameter of the Earth's shadow, the timing and duration of the eclipses, and the size of the eclipsed part of the sun or moon.<\/span><\/li>\r\n<\/ul>\r\n<\/li>\r\n\t<li style=\"font-weight: 400\"><b>Circumference of the Earth:<\/b><span style=\"font-weight: 400\"> Aryabhata also revealed that the circumference of the Earth is 39,968km. It is 40,072 km according to modern scientific calculations.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Reflected Sunlight: <\/b><span style=\"font-weight: 400\">Aryabhata correctly stated that the Moon and planets shine because they reflect sunlight. This was a major scientific insight in ancient astronomy.<\/span><\/li>\r\n<\/ul>\r\n<h3><span style=\"font-weight: 400\">Aryabhata Contribution to Mathematics<\/span><\/h3>\r\n<p><span style=\"font-weight: 400\">Aryabhata\u2019s mathematical work is one of his most enduring achievements.
