Sun theory

The sun theory is the name of many theories-groups of texts. This is the famous volume of Indian astronomy. The text available at the present time seems to be a compilation written in medieval times, but this text is based on old versions which are considered composed in the early 6th century.

Indian mathematicians and astronomers have also d it, such as Aryabhata and Varahamihira, etc. Varahmihir has mentioned it in his Panchasiddhika including four other commentaries, which are:

The work described as Surya Tantra has been molded many times. Its earliest mention is found in the Buddhist period (Third Century, BC). It indicates the middle period of work, preserve and edited (in 1858 by Burgas). A tenth century commentator of Varahmihir, has quoted six verses from the Sun theory, one of which is no longer found in this theory. The present sun theory can then be considered as a direct descendant of available text available to Varahamihira. In this article, the version edited by Burgas will be found only. See the evidence of the occult epoch, to read them, the therapeutic principle.

Here are the rules given by which the motion of cosmic bodies can be known along with their actual position. These conditions of different stars, except for the constellations of the Moon Also makes the knowledge of the situation. By this, solar eclipse can also be assessed.

Subject matter There is a detailed description of astronomical time chakras in the Surya Siddhanta. Astronomy

The following is a list of topics in this text:

The pure methods of timing measurements by the solar clock are described in chapters 3 and 13. Time cycle

The time-cycles described in this book were unconsciously pure. Hindu Cosmic Time Chakras come in the verses 11-23 of the first chapter of the Sun Theory:

"(Verse 11). The one who starts with breath (prana) is called reality, and that which starts with error is called a real, six vows are made from a breath. The pulse is formed.

(Verse 12). And one day (day and night) is formed from sixty nerves. From thirty days a month (month) is formed. A citizen (Sawan) month is equal to the number of sunrises.

(Verse 13). A moon mass is made up of so many moon dates. A solar month is sure to enter the sun's zodiac sign. Twelve months make one year. One year is called a day of the Gods.

(Verse 14). The days and the nights of the gods and the demons are reciprocal. Six of them are six (sixty) years of deities. Similar demons are also there.

(Verse 15). Twelve thousand thousand (thousand) divine years are called a Chatyuga. A chaturag is about 33 million solar years.

(Verse 16) are the four days of Chaturugi and the evening. The difference between the ages of Satyuga and Satyuga and other eras, as measured, is as follows:

(Verse 17). By multiplying the tithi of a quadruple, respectively, by four, three, two, and one, the period of katyuga and other eras is given. The sixth part of all of them is their summer and evening.

(Verse 18). The seventy-four chaturugi are the age of a manvantar or a manu. At the end of it is the evening, whose period is equal to one Satyuga and it is a catastrophe.

(Verse 19). There are fourteen monventers in one sentence, with their evening; At the beginning of each Era, there is the fifteenth evening / Usha. This is also equal to Satyuga.

(Verse 20). In an eclipse, there are one thousand quadrilateral and then there is a catastrophe. This is a day of Brahma. After this there is such a long night.

(Verse 21). By this day and night assessment, his age is one hundred years; His half age has passed, and from the rest it is the first plan.

(Verse 22). In this era, six Manu, including his evening, has now passed the seventh quadrangle of seventh Manu (the son of Vaishavat Vivaswan (Sun)).

(Verse 23). At present, the age of twenty eight years has passed ......... When assessing the astronomical time cycle, the following results are found.

The exact value given by the nakshatriya year is not as pure as it is. Its value is 365.258756 days, which is 3 minutes and 27 seconds less than the modern value. This is because, as the authors, or editors, after calculations made later, the Hindu cosmic time is slightly different from the calculation of Chahra and it is calculated here. He probably did not understand the calculation of complex calculations of the time cycle. The editor has used the average speed and equal precision of the sun, which is lower than the estimation of Hindu Cosmic Time Chakra. Planetary diameter

The diameter of the planets is also computed in the solar system. The diameter of Mercury has been given 3008 miles, which is only 1% less than the modern accepted value (3032 mi). In addition, the diameter of Saturn, Mars, Venus and Jupiter is also calculated. Saturn's diameter is 73882 miles, which is only 1% unclean. Mars is said to be 3772 miles, which is approximately 11% unclean. The diameter of Venus is 4011 miles and the diameter of Jupiter is 41624 miles, which is almost half the current accepted values. Trigonometry

The sun theory is the root of the modern trigonometry. In this, the formula (sine), cosine formula (cosine or "perpendicular sign") and the enlum sign (reverse sign) is used first. It contains the first time, and also includes the earliest use of the tangent and secant.

Of [the sun's meridian zenith distance] find the jya ("base sine") and kojya (cosine or "perpendicular sine"). If then the jya and radius be multiplied respectively by the measure of the gnomon in digits, and divided by the kojya, the results are the shadow and hypotenuse at mid-day.

In modern notation, this gives the shadow of the gnomon at mid-day as

s = g without & # x2061; & # x03B8; cos & # x2061; & # x03B8; = g tan & # x2061; & # x03B8; {\displaystyle s={\frac {g\sin \theta }{\cos \theta }}=g\tan \theta }

and the hypotenuse of the gnomon at mid-day as

h = g r cos & # x2061; & # x03B8; = g r 1 cos & # x2061; & # x03B8; = g r sec & # x2061; & # x03B8; {\displaystyle h={\frac {gr}{\cos \theta }}=gr{\frac {1}{\cos \theta }}=gr\sec \theta }

where & # xA0; g {\displaystyle \ g} is the measure of the gnomon, & # xA0; r {\displaystyle \ r} is the radius of the gnomon, & # xA0; s {\displaystyle \ s} is the shadow of the gnomon, and & # xA0; h {\displaystyle \ h} is the hypotenuse of the gnomon.

Kindergarten experiment

The Indian solar and lunisolar calendars are widely used, with their local variations, in different parts of India. They are important in predicting the dates for the celebration of various festivals, performance of various rites as well as on all astronomical matters. The modern Indian solar and lunisolar calendars are based on close approximations to the true times of the Sun’s entrance into the various rasis.

Conservative "panchang" (almanac) makers still use the formulae and equations found in the Surya Siddhanta to compile and compute their panchangs. The panchang is an annual publication published in all regions and languages in India containing all calendrical information on religious, cultural and astronomical events. It exerts great influence on the religious and social life of the people in India and is found in most Hindu households.
