1. Statue Of Ramanujacharya

1.1 According to Vishishtadwaita (qualified monism)

The living entities are believed to be qualitatively one with the Supreme and at the same time quantitatively different. Ramanuja's assertion was that the quantitative difference means that the fragmentary parts of the Supreme are dependent on the Supreme but they cannot become the Supreme.
According to this philosophy the living entities are individual personalities, so too is the Supreme also a personality-the Ultimate Personality.
The material world is the energy of Godhead, and the subjective reality does not undergo any change of substance in the matter of material manifestation.
About the end of the tenth century, the Visishtadvaita system of philosophy was well established in Southern India and the followers of this creed were in charge of important Vaishnavite temples.
A 216-foot tall statue of Vaishnavite saint Sri Ramanujacharya is set to be unveiled in Hyderabad soon.

It will become the world’s second tallest statue and will be called as Statue of Equality, after the statue of the Great Buddha of Thailand (302 feet).
It is made of panchaloha (an alloy of gold, silver, copper, brass and tin/lead) and its base depicts 36 elephants and 27-feet-high lotus petals.
Near the statue will be another idol of the saint made of gold, weighing 120 kg for regular worshipping.

1.3 About Ramanujacharya

Ramanujacharya, or Ilaiya Perumal is a South Indian Brahman theologian and philosopher, the single most influential thinker of devotional Hinduism.
He was a bhakti saint and also spread the message of equality. His philosophy became known as vishishtadwaita or qualified non-dualism. His philosophical foundations for devotionalism were influential to the Bhakti movement.
His disciples were likely authors of texts such as the Shatyayaniya Upanishad. himself wrote influential texts, such as bhāsya on the Brahma Sutras and the Bhagavad Gita, all in Sanskrit.
He provided an intellectual basis for the practice of bhakti (devotional worship) in three major commentaries: the Vedartha-Samgraha, the Shri-Bhashya and the Bhagavadgita-Bhashya.

Raman Spectroscopy

Raman spectroscopy is one of the vibrational spectroscopic techniques used to provide information on molecular vibrations and crystal structures.
This technique uses a laser light source to irradiate a sample, and generates an infinitesimal amount of Raman scattered light, which is detected as a Raman spectrum.

Raman scattering (Raman effect)

When light is scattered by matter, almost all of the scattering is an elastic process (Rayleigh scattering) due to which there is no change in energy.
However, a very small percentage of scattering is an inelastic process (Raman scattering), thus a scattered light has different energy from incident light.
Raman Spectroscopy been is now being used to ascertain if gold or gemstones on Thanjavur paintings are fake or not.
