The sutras, though not devoted to pure mathematics, are the world's 1st treatises on it.They contain the seminal discoveries not just of Geometry, but also of Algebra & maybe even the place value. Their deserved recognition in the history of Math is denied https://twitter.com/JoeAgneya/status/958285734388973569

The Sulba Sutras were so inconvenient for the Mullerian gang trying to undermine Vedic culture and make it secondary to Mesopotamia and Greece, they forced so many arbitrary dates on so many CRITICAL texts. And their successors still get away with such gross incompetence.

It is very remarkable that such an archaic work would try to deal with irrational numbers. It was only much later that Aryabhatta would recognize 'irrationality'. Many different approaches are found in the different sutras to obtain pi in a wide range of values 2.99 to 3.2022

It is interesting that humans first stumbled upon irrational numbers when trying to construct a Vedic fire altar. The root of 2 was one that challenged the Vedic Purohits/mathematicians. In the sutras the following solution is found,giving a value 1.412156.. correct to 5 decimals

Though the equation may be used to argue that Apastamba & Manava thought root 2 was an exact number,and didn't know irrationality, they were interested in practical use, not the stone hard modern approach. Many later Indian texts clearly state these cannot be exactly determined

The Pythagorean(or Baudhayana to be truthful) triples obtained in the Sulba sutras are-

5, 12, 13

8, 15, 17

12, 16, 20

12, 35, 37

5, 12, 13

8, 15, 17

12, 16, 20

12, 35, 37

Contribution to Algebra- The Quadratic equations make their first appearance in literature in the sutras of Baudhayana, Manava and Apastamba- the first men with whose names the history of Mathematics SHOULD start.

The forms ax2 = c and ax2 + bx = c are seen.

The forms ax2 = c and ax2 + bx = c are seen.

Another beautiful achievement of these late Vedic minds is having formulated probably the world's OLDEST formula for calculating square roots. Here, for calculating the irrational root of 10, a is taken as 9 and r is 1. You get 3.162278, correct to 6 decimal places.

There is nothing wrong if the west wishes to call Galileo the 'Father of modern Physics', but refusing to acknowledge that his work is not entirely original and had heavily drawn on the manuscripts of Aryabhata, Bhaskara etc is unacceptably Eurocentric. https://twitter.com/maxplanckpress/status/964176283394564096

Already stated a 100 times, but it's implications cannot be allowed to go unrecognized:- Europe was digesting the manuscripts of the Indian Trio- Aryabhatta, Brahmagupta & Bhaskara for close to 500 years before Galileo threw things down the tower of Pisa & apples fell on Newton.

The Aryabhatiya contains explicit affirmations of the relativity of motion. Aryabhatta was not only fully aware of the concept, he also worked on some of the fledgeling "equations" of modern physics such as relative velocity(gati). Shouldn't his ideas be compared with Galileo's?

Just like Tycho Brahe stole the erroneous planetary model of Neelakanta, Galileo chose to use the exact same analogy used by Aryabhatta to describe relativity- a thousand years later.

THE BOAT!

Verses 9 and 10 of Aryabhatiya's astronomy section describe it.

THE BOAT!

Verses 9 and 10 of Aryabhatiya's astronomy section describe it.

"Similar to a person in a boat moving forward who sees the stationary objects

on the bank of the river as moving backwards, the stationary stars at Lanka (equator) are viewed as moving westwards"

Aryabhatta wonderfully describes two things here.

on the bank of the river as moving backwards, the stationary stars at Lanka (equator) are viewed as moving westwards"

Aryabhatta wonderfully describes two things here.

He brings to account the earth's rotation in the same verse. The boat has an independent uniform motion, while the movement of the stars is rotational. People on a boat and all people on earth witness the same principle!

Aryabhatta discusses the opposite experiences of observers in the north and south poles of the earth, variance between latitude and time and even hints the force(Gurutva) which prevents people from falling off the earth- something explicitly done before him in the Surya Siddhanta

Verse 31 is the cherry on the cake. One must remember that this is the 5th century AD(possibly older), when Europe(and most of the world) was contributing nothing just like India after Mohammadan invasions. Imagine the light the Aryabhatiya must have been to Arabs & Europeans

"Divide the distance between the 2 bodies moving in the opposite

directions by the sum of their speeds, and the distance between the two bodies moving in the same direction by the difference; this will give the time

elapsed since the two met or before they will meet"

-Aryabhatta

A. Parakh and Roopa H Narayan drew attention to the seminal ideas of physics contained in the Aryabhatiya and their probable influence on later day Europe.

How did the Aryabhatiya and its path breaking algebra, trigonometry and astronomy enter the Arab and western world?

According to the Tabqatul-Umam written by Said al-Andalusi(1029–1070AD) a scientific delegation led by an Indian astronomer Kanaka visited Baghdad itself!

He carried only a small collection- but it contained the most catalytic of all combinations. The most advanced manuscripts on earth then. He gave this priceless trilogy to the Caliph of Islam.

But can we call him a traitor? Sharing knowledge freely was in the nature of the Vedic culture he came from. Never in his wildest dreams would he have imagined that the Arabs and the Latins would scavenge on it, plagiarize it & later put a racial identity & a price tag on science

Arab historian Al-Qifti(~1200AD) reports that the Caliph(or more likely his Persian astronomers) was so amazed that ordered them to be translated to Arabic. Al-Fazari did that job. And he became the first 'Arab astronomer' of renown. His famous work is Zīj al-Sindhind(siddhānta).

The sindhind spread all over the muslim world, incl Spain. In the library of Toledo was the great repository of centuries of manuscripts, translations and commentaries. By 1100AD, all of it fell into the hands of the church. Mass Latin translations and appropriation began.

The Indian astronomical tables had been compiled by the astronomers at Toledo and was known as the 'Toledo tables' which accurately predicted motions of celestial bodies. By 1270, Alfonso of Castile turned them into 'Alfonsine tables'. Vedic origins vanished there-and remains so.

Sanskrit jyā & koti-jyā became sine & cosine.

One must admit, the Arab/Persian scholars were far more intellectually honest than the Nicky Copernican & Christo Clavian gangs.

Kanaka led the scientific delegation to Baghdad in the year 771 AD, a hundred years after Brahmagupta died. That was the year the baton of reason was given to foreigners.

In a way it was good. Indian mahaviharas & institutions were going to be destroyed in the next few centuries.

In a way it was good. Indian mahaviharas & institutions were going to be destroyed in the next few centuries.

But that does not mean the story was over in India. Part 2 was beginning.The Arabs and Latins were not capable of advancing science to the next level- The analytical level of calculus. Because they simply did not have the cultural/philosophical sophistication to conceive of it.

They used the numerals, place value and the basic math for trade, navigation & astronomy. The clumsy Roman numerals were wiped out of use, though tally sticks had to be forcibly burned even in 18th CE. A commendable achievement was the standardisation of heliocentrism by Keplar.

While the Church scholars of the 12th-13th CE were busy translating and manufacturing manuscripts to attribute everything to Greeks, in India, the Trilogy had already reached the South, where Bhaskara and the Kerala mathematicians would painstakingly expand them & invent calculus

The Vedic circle method is described in the youngest Sulba-Sutra but it is very probably MUCH older.

"Although its earliest description is in the Katyayana Sulba-sutra, it is believed to have been used in the east-west alignment of Harappan structures." http://indianexpress.com/article/explained/in-pyramid-perfection-hint-of-a-variant-on-an-indian-tool-5073312/

One wonders-If archaeological evidence for such math & technology in India is found only in the Harappan era and if literary attestation is found only in Vedic SulbaSutras-What is difficult in accepting they both represent the same culture?

Baudhayana & Apasthamba were Harappans!

Who was Leonhard Euler?

He- like Newton, Gregory etc- 'independently rediscovered' a 1000 year old Indian mathematical method. This time from Aryabhatta himself. The "Euler's method" for ordinary differential equations https://twitter.com/CUP_SciEng/status/985525759442849792

In Ganita 12 , Aryabhatta mentions the use of the numerical method of sine differences, though in a cursory verse. It was elaborated further by Brahmagupta.

How do we know Euler was studying Indian manuscripts?

He published an elaborate article on the Indian calender in 1700.

He gets even bolder/dumber and adds-

In other words, he implies that plagiarism can be established only if the plagiarists self damningly gives attribution to their true sources.

Just wow.

Dear reader, let that sink in.

The most intelligent man on earth at that time- Sankara Variar-was serving a king who was literally enthralled to the Portuguese

At a time when the Jesuits were manuscript hunting to learn Indian trigonometry just to reform the Julian calendar.

2. Coming back, let us give @thewire_in the 2nd DOCUMENTED evidence of European contact with KSOM.

"I am trying to learn the methods of reckoning time from an intelligent Brahmin."

-Matteo Ricci wrote to Petri Maffei in Dec 1581

That Brahmin was probably a disciple of Sankara

The original words in Portuguese-

“Com tudo não me parece que sera impossivel saberse, mas has de ser por via

d`algum mouro honorado ou brahmane muito intelligente que saiba as cronicas dos tiempos, dos quais eu procurarei saber tudo”

Reproduced in Documenta Indica, XII (p 474)

Now we can TRULY appreciate how UTTERLY wrong the article's 'sequential development' statement is

Clavius whose lifelong work was decimal system & Indian trigonometric tables died in 1612. Newton was born in 1642

The Vedanga Jyotisha(~1370 BCE)was already declared outdated by Varahamihira 1000 yrs before Nobili

Obviously neither Nobili nor his master Clavius was capable of digesting the latest, most advanced Indian texts-Yuktibhasa & Yuktidipika

That required the services of Newton & Co
