GENERAL I ARTICLE Aryabha~a and Axial Rotation of Earth 2. Naksatra Dina (The Sidereal Day) Amartya Kumar Dutta In the first part of this series, we discussed the celestial sphere and .Aryabhata's principle of ax ial rotation; in this part we shall discuss in de tail the concept of sidereal day and then men tion .Aryabhata's computations on the duration of sidereal day. Amartya Kumar Dutta is in the Stat-Math Unit of It. is unfortunate that science students in India, by and Indian Statisticallnstiutte, large, do not have technical awareness regarding the re Kolkata. His research searches of ancient Indian scientists. Thus, although interest is in commutative there are plenty of articles on Aryabhata, their contents algebra. have remained confined to research journals and schol arly texts without percolating into the general cultural Part 1.

It. will not be possible to make a se rious analysis of the entire range of Aryabhat.a's work in a few pages. We hope that the preliminary exposure will encourage youngsters to acquire some general know ledge of astronomy and make a deeper study of A.ryabhata's work using existing literatures and their own indepen dent judgements.

Chapter Two Astrological Works in Sanskrit
51 CHAPTER TWO ASTROLOGICAL WORKS IN SANSKRIT Astrology can be defined as the 'philosophy of discovery' which analyzing past impulses and future actions of both individuals and communities in the light of planetary configurations. Astrology explains life's reaction to planetary movements. In Sanskrit it is called hora sastra the science of time-'^rwRH ^5R5fai«fH5iref ^ ^Tm ^ ^ % ^i^J' 11 L.R. Chawdhary documented the use of astrology as "astrology is important to male or female as is the case of psychology, this branch of knowledge deals with the human soul deriving awareness of the mind from the careful examination of the facts of consciousness. Astrology complements everything in psychology because it explains the facts of planetary influences on the conscious and subconscious providing a guideline towards all aspects of life, harmony of mind, body and spirit. This is the real use of astrology^. Dr. ^.V.Raman implies that "astrology in India is a part of the whole of Indian culture and plays an integral part in guiding life for all at all stages of life" ^. Predictive astrology is a part of astronomy that exists by the influence of ganita and astronomical doctrines. Winternitz observes that an astrologer is required to possess all possible noble quantities and a comprehensive knowledge of astronomy, ' Quoted from Sabdakalpadruma, kanta-ll, p.550 ^ L.R.Chawdhari, Secrets of astrology.

Histroy of Astrology
THE HISTORY OF ASTROLOGY THE HISTORY OF ASTROLOGY Astrology consists of a number of belief systems which hold that there is a relationship between visible astronomical phenomena and events in the human world. In the West, astrology most often consists of a system of horoscopes that claim to predict aspects of an individual's personality or life history based on the positions of the sun, moon, and planetary objects at the time of their birth. Many other cultures have attached importance to astronomical events, and the Indian, Chinese, and Mayan cultures developed elaborate systems for predicting terrestrial events from celestial observations. Source : Wikipedia, the free encyclopedia THE HISTORY OF ASTROLOGY Astrology’s origins in Indo-European cultures trace to the third millennium BCE, with roots in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Through most of its history it was considered a scholarly tradition. It was accepted in political and academic contexts, and its concepts were built into other studies, such as astronomy, alchemy, meteorology, and medicine. At the end of the 17th century, new scientific concepts in astronomy (such as heliocentrism) began to damage the credibility of astrology, which subsequently lost its academic and theoretical standing. Astrology saw a popular revival in the 19th and 20th centuries as part of a general revival of spiritualism and later New Age philosophy, and through the influence of mass media such as newspaper horoscopes. ETYMOLOGY The word astrology comes from the Latin astrologia, deriving from the Greek noun αστρολογία , which combines ἄἄἄστρο astro, 'star, celestial body' with λογία logia, 'study of, theory, discourse (about)'. -

On the Laws of Planetary Motions by Aryabhatta I and Kepler

He came up with three th lived in Pataliputra I in the 5 century AD (476-550) and laws governing their motion. These laws are: Kepler (1571-1630). The history of astronomy is reviewed where this contribution by Aryabhatta was not commonly 1) Every planet's orbit is an ellipse with the Sun at known to public or among the scientific community. Kepler’s a focus; laws are very widely known throughout the world. 2) A line joining the Sun and a planet sweeps out The findings of this work is that the Aryabhatta’s laws equal areas in equal times; and more accurately represent the planetary motions than those of 3) The square of a planet's orbital period is Kepler even though they were written about 1000 years earlier. proportional to the cube of the semi-major axis of its orbit. In other words, his third law states that 1.

Aryabhata's Mathematics Introduction
Aryabhata’s Mathematics Subhash Kak Introduction This paper presents certain aspects of the mathematics of Āryabha ṭa (born 476) that are of historical interest to the computer scientist. Although Āryabha ṭa is well known in history of astronomy, the significance of his work to computing science is not as well appreciated and one of the objectives of the 2006 RSA Conference was to address this lacuna. The cryptographic community has recently become aware of Āryabha ṭa because his algorithm to solve congruences can be used in place of the Chinese Remainder Theorem in certain situations [33]. His code has had applications in securing passwords and personal identification numbers [37],[38]. Very little is known of the personal life of Āryabha ṭa, and the summary that follows is based on my essays in Scribner’s Encyclopedia of India [1]. He was born in A śmaka but later lived in Kusumapura, which the commentator Bhāskara I (c. 629) identifies with Pāṭaliputra (modern Patna). It appears that he was the kulapati (head) of the University at Nāland ā in Magadha [2]. There is no agreement about the location of A śmaka, but since the Āryabha ṭian school has remained strong in Kerala in South India, some believe that he may have belonged to that region. In addition, Āryabha ṭa employed the Kali era (3102 BC) which remains popular in South India. The A śmaka people were taken in early literature to belong either to northwest India or the region in South India between the rivers God āvar ī and Narmad ā. Āryabha ṭa wrote at least two books: the Āryabha ṭīya and the Āryabha ṭa-siddh ānta , of which the latter is known only through references in other works. -
Astronomy in India
Astronomy in India From pre-history to advent of telescope Origin of Astronomy As human being gathered capacity to wonder at, and indulge in certain amount of speculation The regularity of appearance and disappearance of these objects should have impressed them. the sequence of day and night, and the obvious connection of the sun the periodic waxing and waning of the moon the unchanging character of the stellar vault Origins.. Primitive societies noticed that the hunting seasons changed along with the periodic change in the night sky. Animals and birds migrated with seasons… Soon primitive agriculture settlements emerged In agricultural societies sowing and other operations depended on climatic changes or the seasons. The seasons arrived with appearance of certain groups of stars and changed with the arrival of others. Proto astronomy in India Just as any civilization, in India too proto-astronomy is seen even at the time of dawn of civilization Lunar calendar sticks from Nicobar Islands. waxing and waning of moon is recorded. The stick belongs to upper Paleolithic period. ( 11000 to 8000 years BP) In addition we have engraved Ostrich egg shell in an open campsite, upper paleolithic layer near Patna and bone engraved with cross hatching in an upper paleolithic layer and another in a mesolithic layer at Bhimbhetka Astronomy in folk tradtion… in Andhra, the Orion is called as `prongs of a plough' (gorakoaiahlu or gorthi koaiahlu in Telugu) not by the traditionally known name of Mrigsirsha, the Pleiades is called a `hen with chicks' (pillalakodi), and not as Krittikas. In Tamil this group of star is called „Addupu‟ meaning „three stone stove‟. -
