Chaandra Siddhanta II
Chandra Siddhanta II, Theory of Luna
In the Orient, Lalla contributed heavily to the Lunar Theory, as did Newton, Ptolemy & Brahe in the Occident !
Both are great Civilizations and none plagiarized from the other !
John Playfair, mathematician,
Extolled the Eternians,
For their possession of a Calculus
Equivalent to Trignometry.
( Did not Einstein say
Indians taught us Maths ?
Or the great Laplace, that System Decimal
Is Indian in origin ? )
The multi step algorithms
Of mighty Hindu Astronomy
Is known as Graha Sphuta Ganita,
Base of all Panchang computations.
We have not defined Vipata Kendra,
The Vipata Anomaly,
Vi means without
Patha means Node.
Vipata Anomaly means Angle
Between Position and Node.
This is the Second Correction,
Position reduced to Ecliptic.
Manda Anomaly means Angle
Between Position and Aphelion
Sheeghra Anomaly means Angle
Between Position and Sun
By Position we mean
The Position of the Planet.
Aphelion is a Point,
180 degrees away from Perihelion.
Of the Fourteen Kendras plotted
The First One deals with the Annual Equation
Moon accelerates during July
And decelerates during Jan !
First Kendra Sin ( Mr + 180 ) * 658
The Second dealt with Equation Parallactic
Sun’s perturbing action on Luna
Creates inequalities in her motion
Second Kendra Sin ( Lc – Lr ) * 121
The Third dealt with Evection,
Moon seems to be carried away
By the Sun’s celestial pull !
Third Kendra Sin ( 2*T – Mc ) * 4467
The Fourth deals with The Variation
Moon accelerates at 0 and 180
And decelerates at 90 and 270
Fourth Kendra Sin ( 2*T + 6 Signs ) * 2145
All these Four
Are major perturbations.
Ten more are there
Needing corrections trignometric!
Anomaly is defined as the Angle
Between Position & Perihelion
There is no Eccentric Anomaly,
In Indian computations !
