WHY THE TERRACOTTA ARMY SWORDS ARE SHINY AFTER 2,000 YEARS.

Scientists have decoded how the bronze weapons of China's iconic Terracotta Army remained pristine and shiny despite being buried for nearly 2,000 years. The team found that the chrome plating on the weapons - once thought to be the earliest form of anti-rust technology - derives from a decorative varnish rather than a preservation technique. The study, published in the Journal "Scientific Reports', reveals that the chemical composition and characteristics of the surrounding soil, rather than Chromium, may be responsible for the weapons' famous preservation power.

VIEWS OF MANU AND KAUTILYA ON THE ADMINISTRATION OF JUSTICE.

The state performed its duty of protection of society and the individual through coercive enforcement of the standards of justice based on the concept of ' Dharma '. From the Vedic period onward, the perennial attitude of Indian culture had been justice and righteousness. Justice, in the Indian context, was a human expression of a wider universal principle of nature and if men were entirely true to nature, their actions would be spontaneously just. Men experienced Justice, in the sense of a distributive equity, as moral justice, social justice, and legal justice.

The ethical code of society and its cultural standards were inter-related. The cultural maturity and social amicability and even their det...

ANCIENT INDIA'S LINKS TO TODAY.

You may not have heard of Shu-ilishu but he is a man of great significance. He reaches out to us from almost 4,300 years ago, through a small Akkadian cylinder seal now housed at the Louvre Museum in Paris. On the seal, you will find an image of him talking to two men. The inscription describes Shu-ilishu as the interpreter of the Meluhhan language. 'Meluha' was, in all probability, the term used by ancient Mesopotamians for the Indus Valley region, and the presence of an oficial 'interpreter' there indicates just how important the steady flow of good from the Indian sub-continent was.  Precious and vibrant lapis lazuli stones, carnelian beads, wood and even dogs would go across via old trade routes and ports like Lothal (in modern-day Gujarat) to Akkad, capital of the Akkadian Empire (03rd millennium BCE) and now in modern-day Iraq. There are also references to a settlement of Meluhhans in the city of Guabba in Sumer, in Mesopotamia.  The story of Shi-ilishu and ...
