mathematics came from Afghanistan, there would be no algebra today if it wasn't for muslims. medicine came from muslims, in the time of the prophet physicians knew how to do blood transfussions.
Algebra... Pythagoras Theorem, Zero.. .All a combination of work from different places. Pythagoras Theorem and the zero are though to have to have come from India, as well as algebra.
Baudhayana (c. 8th century BCE) composed the
Baudhayana Sulba Sutra, which contains examples of simple
Pythagorean triples, such as: (3,4,5), (5,12,13), (8,15,17), (7,24,25), and (12,35,37)
[26] as well as a statement of the
Pythagorean theorem for the sides of a square: "The rope which is stretched across the diagonal of a square produces an area double the size of the original square."
[26] It also contains the general statement of the Pythagorean theorem (for the sides of a rectangle): "The rope stretched along the length of the diagonal of a rectangle makes an area which the vertical and horizontal sides make together."
The concept of
0 as a number, and not merely a symbol for separation is attributed to India.
[73] In India, practical calculations were carried out using zero, which was treated like any other number by the 9th century CE, even in case of division.

He states that the
Moon and planets shine by reflected sunlight. Instead of the prevailing cosmogony where eclipses were caused by pseudo-planetary nodes
Rahu and
Ketu, he explains eclipses in terms of shadows cast by and falling on earth. Thus the lunar eclipse occurs when the moon enters into the earth-shadow (verse gola.37), and discusses at length the size and extent of this earth-shadow (verses gola.38-48), and then the computation, and the size of the eclipsed part during eclipses. Subsequent Indian astronomers improved on these calculations, but his methods provided the core. This computational paradigm was so accurate that the 18th century scientist
Guillaume le Gentil, during a visit to Pondicherry, found the Indian computations of the duration of the
lunar eclipse of
1765-
08-30 to be short by 41 seconds, whereas his charts (by Tobias Mayer, 1752) were long by 68 seconds

Aryabhata's computation of Earth's
circumference as 39,968.0582 kilometers, which was only 0.2% smaller than the actual value of 40,075.0167 kilometers. This approximation was a significant improvement over the computation by the
Greek mathematician,
Eratosthenes (c. 200 BCE), whose exact computation is not known in modern units but his estimate had an error of around 5-10%
the earliest traces of a
counter-intuitive idea that it is the Earth that is actually moving and the Sun that is at the center of the solar system is found in Vedic and post-Vedic texts
[2][3] such as
Shatapatha Brahmana, which has, according to
Subhash Kak[
unreliable source?]: "The sun is stationed for all time, in the middle of the day. [...] Of the sun, which is always in one and the same place, there is neither setting nor rising.
