Aryabhata... Aryabhata आर्यभट/ आर्यभट्ट (476–550 CE) mentions the reasons for eclipse in no unclear terms. चन्द्रो जलमर्कोऽग्निर्मृद्भूश्छायापि या तमस्तद्धि | छादयति शशी सूर्यं शशिनं महती च भूच्छाया || [आर्यभाटीय, गोलपादः 37] chandro jalam_arko'gnir_mRid_bhUsh_chhAyApi yA tamas_taddhi | chhAdayati shashI sUryam shashinam mahatI cha bhUch_chAyA || [i.e. chandraH jalam, arkaH agni, mRit bhUH, chAyA api yA tamaH tat hi chAdayati shahI suryam, shashinam mahatI cha, bhUH chAyA ] [AryabhAtIya, Gola-pAdaH 37] "moon is of water, sun is of fire, earth is of soil, and its shadow is of darkness. the moon covers the sun, and the great shadow of the earth covers the moon." [The book of Aryabhata, Sphere section, #37] He then discusses in detail, how to calculate the size of Earth's shadow and the size of the eclipsed part. These computations were improved by later astronomers a bit. His calculations were so accurate that 18th century scientist Guillaume Le Gentil, during a visit to Pondicherry, India, found the Indian computations of the duration of the lunar eclipse of 30 August 1765 to be short by 41 seconds, whereas his charts were long by 68 seconds. (Wikipedia) Considered in modern English units of time, Aryabhata calculated the sidereal rotation (the rotation of the earth referencing the fixed stars) as 23 hours, 56 minutes, and 4.1 seconds; the modern value is 23:56:4.091. Similarly, his value for the length of the sidereal year at 365 days, 6 hours, 12 minutes, and 30 seconds (365.25858 days) is an error of 3 minutes and 20 seconds over the length of a year (365.25636 days). He even gave the times for Jupiter's revolution, distance of Sun and earth, earth circumference. He also pioneered in trigonometry and trigonometric calculations. Tables of sine and cosine of angles were calculated that are even today precise to 3-4 places of decimal point. Some of his statements on astronomy, in AryabhAtIya golapAda chapter, worth noting are: 1. Sun illuminates half of the earth, moon and planets, the other half remains dark. [5] 2. Heavenly bodies seem to move westward at equator, similar to parallax by which the forest seems to move from a moving boat. [9] 3. Sri Lanka 90 degrees from pole, Ujjain 22.5 degree north of Lanka. [14] 4. Cause of eclipses due to shadow of moon and earth and many calculations around it. [37]5. Color of moon at different parts of total eclipse! [46] 6. At poles, Sun visible for 6 months, on moon, sun visible for half a lunar month! [17] He did a lot more in mathematics including calculating the value of Pi correct up to 4 decimal places and knowing that it was indeterminate. Adding sequence of squares and cubes, and finding solutions to what is now called as Diophantine equations (Ax + By = C, A, B, C are integer, find integer solutions for x and y)

Spartan Posted October 7, 2014 Report Posted October 7, 2014 Astronomy Aryabhata's system of astronomy was called the audAyaka system, in which days are reckoned from uday, dawn at lanka or "equator". Some of his later writings on astronomy, which apparently proposed a second model (or ardha-rAtrikA, midnight) are lost but can be partly reconstructed from the discussion in Brahmagupta's khanDakhAdyaka. In some texts, he seems to ascribe the apparent motions of the heavens to the Earth's rotation. He may have believed that the planet's orbits as elliptical rather than circular.[21][22] Motions of the solar system Aryabhata correctly insisted that the earth rotates about its axis daily, and that the apparent movement of the stars is a relative motion caused by the rotation of the earth, contrary to the then-prevailing view, that the sky rotated. This is indicated in the first chapter of the Aryabhatiya, where he gives the number of rotations of the earth in a yuga,[23] and made more explicit in his gola chapter:[24] In the same way that someone in a boat going forward sees an unmoving [object] going backward, so [someone] on the equator sees the unmoving stars going uniformly westward. The cause of rising and setting [is that] the sphere of the stars together with the planets [apparently?] turns due west at the equator, constantly pushed by the cosmic wind. Aryabhata described a geocentric model of the solar system, in which the Sun and Moon are each carried by epicycles. They in turn revolve around the Earth. In this model, which is also found in the Paitāmahasiddhānta (c. CE 425), the motions of the planets are each governed by two epicycles, a smaller manda (slow) and a larger śīghra (fast). [25] The order of the planets in terms of distance from earth is taken as: the Moon, Mercury, Venus, the Sun, Mars, Jupiter, Saturn, and the asterisms."[8] The positions and periods of the planets was calculated relative to uniformly moving points. In the case of Mercury and Venus, they move around the Earth at the same mean speed as the Sun. In the case of Mars, Jupiter, and Saturn, they move around the Earth at specific speeds, representing each planet's motion through the zodiac. Most historians of astronomy consider that this two-epicycle model reflects elements of pre-Ptolemaic Greek astronomy.[26] Another element in Aryabhata's model, the śīghrocca, the basic planetary period in relation to the Sun, is seen by some historians as a sign of an underlying heliocentric model.[27]
