    This is in continuation of my earlier article History of Mathematics Preface Bakshali Manuscript.We may now look some ancient Indian treatises on Mathematics.The names that come to one’ s mind are Aryabhatta and Varahamihira.

    Aryabhatta

    Aryabhata (Sanskrit: आर्यभट, ISO: Āryabhaṭa) or Aryabhata I (476–550 CE) was an Indian mathematician and astronomer of the classical age of Indian mathematics and Indian astronomy. He flourished in the Gupta Era and produced works such as the Āryabhaṭīya (which mentions that in 3600 Kali Yuga, 499 CE, he was 23 years old) and the Arya-siddhanta.Aryabhata (Sanskrit: आर्यभट, ISO: Āryabhaṭa) or Aryabhata I(476–550 CE) was an Indian mathematician and astronomer of the classical age of Indian mathematics and Indian astronomy. He flourished in the Gupta Era and produced works such as the Āryabhaṭīya (which mentions that in 3600 Kali Yuga, 499 CE, he was 23 years old) and the Arya-siddhanta.

    His major work, Aryabhatiya, a compendium of mathematics and astronomy, was extensively referred to in the Indian mathematical literature and has survived to modern times. The mathematical part of the Aryabhatiya covers , algebra, plane trigonometry, and spherical trigonometry. It also contains continued fractions, quadratic equations, sums-of-power series, and a table of sines.

    The Arya-siddhanta, a lost work on astronomical computations, is known through the writings of Aryabhata’s contemporary, Varahamihira, and later mathematicians and commentators, including Brahmagupta and Bhaskara.

    Brahmagupta

    Brahmagupta (c. 598 – c. 668 CE) was an Indian mathematician and astronomer. He is the author of two early works on mathematics and astronomy: the Brāhmasphuṭasiddhānta (BSS, “correctly established doctrine of Brahma”, dated 628), a theoretical treatise, and the Khaṇḍakhādyaka (“edible bite”, dated 665), a more practical text.

    • Brāhmasphuṭasiddhānta,composed in 628 CE.
    • Khaṇḍakhādyaka,composed in 665 CE.
    • Grahaṇārkajñāna,(ascribed in one manuscript.

    Lalla

    Lalla (c. 720–790 CE) was an Indian mathematician, astronomer, and astrologer who belonged to a family of astronomers.

    Śiṣyadhīvṛddhidatantra is his work.

    Panini 5th Century BC

    We know Panini to be the grammarian of Sanskrit Language . He was an illustrious Mathematician too. His notation was similar to modern mathematical notation, and used metarules, transformations, and recursion.Pingala (roughly 3rd–1st centuries BC) in his treatise of prosody uses a device corresponding to a binary numeral system. His discussion of the combinatorics of meters corresponds to an elementary version of the binomial theorem. Pingala’s work also contains the basic ideas of Fibonacci numbers. Read this Mathematical Structures of Ashtadyayi

    Pingala 3- 2 Century BC

    Another great mathematician of ancient India.ancient Indian poet and mathematician, the author of the Chandaḥśāstra (also called Pingala-sutras), the earliest known treatise on Metres.( Chandas,Vedic Metres).The Chandaḥśāstra presents the first known description of a binary numeral system in connection with the systematic enumeration of meters with fixed patterns of short and long syllables. The discussion of the combinatorics of meter corresponds to the binomial theorem. Halāyudha’s commentary includes a presentation of Pascal’s triangle (called meruprastāra). Pingala’s work also includes material related to the Fibonacci numbers, called mātrāmeru.

    The Surya Siddhanta,

    Homage to Brahma, Suryasiddhantha

    The Surya Siddhanta ‘The text is known from a 15th-century CE palm-leaf manuscript, and several newer manuscripts. It was composed or revised c. 800 CE from an earlier text also called the Surya Siddhanta.Now date is arbitrarily assigned as 4/5 Century BC!(According to al-Biruni, the 11th-century Persian scholar and polymath, a text named the Surya Siddhanta was written by one Lāta.The second verse of the first chapter of the Surya Siddhanta attributes the words to an emissary of the solar deity of Hindu mythology, Surya, as recounted to an asura (a mythical being) called Maya at the end of Satya Yuga, the first golden age of Hindu mythology, around two million years ago.Maya has Tamil connection. I shall detail this in another post.The Surya Siddhanta thus consists of cryptic rules in Sanskrit verse. It is a compendium of astronomy that is easier to remember, transmit and use as reference or aid for the experienced, but does not aim to offer commentary, explanation or proof. The text has 14 chapters and 500 shlokas. It is one of the eighteen astronomical siddhanta (treatises), but thirteen of the eighteen are believed to be lost to history. The Surya Siddhanta text has survived since the ancient times, has been the best known and the most referred astronomical text in the Indian tradition. Suryasiddhantha

  • Zero Day Aryabhatta Julian Calendars

    The essential difference between the Hindu Calendar and the Julian Calendar is that the Julian Calendar takes Time as Linear,forward Flowing, while Hinduism states that Time is Circular.

    Time calulation Hinduism
    Hindu Measurement of Time

    The reason for this situation is the assumption that Time is Linear.

    West thinks Time is Linear.

    Time flows in one direction that is forward.
    What if Time is Cyclic?

    That is, it flows around and depending on where you are.

    Time moves both forwards and backwards .

    Time is a stream; so is Space. Per se they are Absolute.

    They are Relative to the observer.

    To put it in simpler words ,things exist in Space and Time at all times irrespective of your positioning and what we say to day has happened ,is right now happening at another level for an observer positioned to observe it

    .

    For them, our Universe is Past.

    Similarly for another observer, what we see as future, may be Present.

    Indian Concept of Time.

    Hinduism advocates Cyclic Theory of Time.

    TIME- Calculation in Hindu Philosophy.

    3.2 seconds- 1 Kaashtai.

    30 Kaashtais or 1.6 minutes or 96 seconds -1 Kalai

    30 kalais or 48 minutes – 1 Muhurtham

    15 Days -one Paksha

    2 Paksas – one Month

    6 Months -one Ayanam

    2 Ayanams -one Year)

    There are Four AEONS (yugas).-In terms of Man-Years.

    I. Kali Yugam 4, 32,000 years.

    II. Dwapara Yuga 8, 64,000years. (Kali x 2)

    III. Tretha Yuga 12, 96,000 years. (Kali x 3)

    IV. Krita Yuga 17, 28,000 years. (Kali x 4)

    V. Total 43, 32,000 years

    For Devas, in the next plane of existence, one year by human calculation is one day.

    Time Non Linear.

    Aryabhatta was the ancient Astronomer and mathematician of India.

    He was the first astronomer of the world

    He used the as Zero Day the beginning of Maha Yuga of Hinduism.

    But as the number of years were innumerable, the beginning of Kaliyuga was taken as  the starting Day by the later Astronomers of India,(from the midnight of 17-18 February 3102 BCE (BC)

    This was called Ahargana.

    Julian Day Number was started by a French Scholar Joseph Scaliger in CE (AD) 1582.

    Julian Calendar uses  Greenwhich mean noon of 1st January, 4713 BCE (BC).
