GHAZI ATTACK OF 1971    The PNS Ghazi was the naval submarine, which was used in the naval battle of India-Pakistan Naval War of 1971 during the Bangladesh liberation war and hence popularly known as "Ghazi Attack".  PNS Ghazi was assigned with a two-fold objective. The primary goal was to find and sink INS Vikrant and the second one was to lay mines on India's Eastern seaboard with or without accomplishing the primary objective.   Finally on November 14, 1971, PNS Ghazi secretly sailed 3,000 miles (over 4,800km)     from the Arabian Sea to Bay of Bengal in a bid to locate and destroy INS Vikrant. Its secondary mission was to plant mines in India's eastern seaboard.   Ghazi started looking for Vikrant on November 23 off Madras but was not aware that she was 10 days too late and the Vikrant was actually somewhere near the Andaman islands.  Indian Navy got wind of the Ghazi's presence off the Sri Lankan coast by local fisherman which was spotted by INS Akshay throug

  The Shunga Empire was an ancient Indian dynasty from Magadha that controlled areas of the central and eastern Indian subcontinent from around 184 to 75 BCE. The founder of the dynasty, Pushyamitra Shunga, overthrew the Mauryas; either in 187 B.C. or 184 B.C. After him there were nine other rulers. Among them, Agnimitra, Vasumitra, Bhagvata and Devabhumi were the prominent ones. The names of the first two were associated with some events in political history, whereas the latter two were known for their long rule.  H. C.

According to some historians, this was an internal revolt against the last Mauryan ki

 Most of the people have seen a honeycomb , and also the hexagonal structure which it resembles. But we have never given it a thought that why only Hexagonal??? Lets explore the significance of this hexagonal structure and relate it to material science . A material with honeycomb structure has minimal density and relatively high out of plane compression properties. Man-made honeycomb structured materials are usually made up by layering a material between two thin layers that provide great strength in tension. credits:- https://www.plascore.com/honeycomb/honeycomb-panels/ The above image shows what exactly happens inside a single honeycomb layer. Honeycomb panel strength works an I beam . The core acts like a vertical element and the facing acts like flange. This combination provides a very high shear strength. Thicker the core , greater will be the strength of material. This kind of material comes under the category of composites. credits:- https://www.plascore.com/honeycomb/honeycomb-
