A Brief history Of Flight

 


The history of flight is a story of human ingenuity, creativity, and perseverance. It is a tale of our never-ending desire to explore and push the boundaries of what is possible. From the earliest attempts at flying to the modern era of commercial aviation and space exploration, flight has played a significant role in shaping our world and changing the way we live.

The story of flight begins with the ancient dream of flight that dates back to the earliest civilizations. Ancient mythologies and folklore from around the world are full of stories about flying gods and heroes. For centuries, humans tried to replicate the flight of birds with crude flying machines, such as kites and gliders.

The first recorded flight attempt was made by Abbas Ibn Firnas, an Andalusian Muslim polymath, in the 9th century. He constructed a rudimentary flying machine, which was made of silk and eagle feathers and was said to have flown for a few seconds before crashing. In the 11th century, the Chinese inventor and scholar, Shen Kuo, wrote about a flying machine called the "fire bird," which was propelled by steam and had wings made of wood and bamboo.

In the 15th century, Leonardo da Vinci, the Italian polymath, sketched designs for flying machines, including a glider and a helicopter. However, these designs remained on paper and were never built during his lifetime.

The first successful manned flight was made by the Montgolfier brothers, Joseph and Étienne, in 1783. They constructed a hot air balloon made of paper and silk, which flew for about 10 minutes with two passengers on board. This historic flight paved the way for the development of other types of aircraft, including the dirigible, which was a type of airship that was powered by an engine and could be steered in different directions.

In the early 20th century, the race to achieve powered flight was on. The Wright brothers, Orville and Wilbur, are credited with building and flying the first successful powered airplane in 1903. Their aircraft, the Wright Flyer, was made of wood and fabric and was powered by a gasoline engine. It flew for 12 seconds and covered a distance of 120 feet. This historic flight marked the beginning of the age of the aviation.

In the following years, aviation technology advanced rapidly. The first commercial passenger flight took off in 1914, and the first transatlantic flight was completed in 1919. Aircraft were used extensively during World War I and II for reconnaissance and bombing missions.

In the post-war years, commercial aviation became more popular and accessible to the general public. The jet engine, which was developed in the 1930's, revolutionized aviation by enabling faster and more efficient flights. The first commercial jetliner, the de Havilland Comet, was introduced in 1952 and marked a new era in air travel. During the 1960s and 70s, the space race between the United States and the Soviet Union led to significant advancements in aerospace technology. The first human spaceflight was made by Yuri Gagarin, a Soviet cosmonaut, in 1961. The United States achieved the first manned moon landing in 1969 with the Apollo 11 mission.

Since then, space exploration has continued to expand, with new discoveries and advancements being made in the fields of astronomy, astrophysics, and space technology. Today, there are plans for manned missions to Mars and the establishment of permanent settlements on the moon.

In addition to commercial aviation and space exploration, flight has played a significant role in military operations, scientific research, and emergency response. Aircraft are used for search and rescue missions, firefighting, and disaster relief efforts. They have also been used to transport humanitarian aid and medical supplies.

What is CTBT( Comprehensive Nuclear-Test-Ban Treaty)?

 



CTBT stands for Comprehensive Nuclear-Test-Ban Treaty. It is a multilateral treaty that bans all nuclear explosions, whether for military or civilian purposes, in all environments. The treaty was adopted by the United Nations General Assembly in 1996 and has been signed by 185 countries and ratified by 170.

The CTBT's main objective is to prevent nuclear explosions and the development of new nuclear weapons by verifying that nuclear tests are not being conducted. This is achieved through the establishment of a comprehensive International Monitoring System (IMS), which consists of a global network of monitoring stations and laboratories that monitor the planet for any signs of nuclear testing.

The CTBT has not yet entered into force, as it requires ratification by eight specific countries listed in the treaty's Annex 2, including the United States, China, and North Korea. However, the treaty has had a significant impact on global efforts to halt the spread of nuclear weapons, and it continues to be an important component of international efforts to promote disarmament and prevent the proliferation of nuclear weapons.

Pig Heart in Human

 


         Heart is a major organ of our human body. On 3 December 1967 a South African cardiac surgeon name Christiaan Neethling Barnard performed first human to human heart transplant operation.The heart of  Denise Darvali a accident victim into Louis Washkansky of 54 years old. After gaining full consciousness  Washkasky died after 18 days.

Now in our question arises.....  Can a pig heart can replace a human heart???

At the university of MarylandMedical Centre on January 7, 2022. Bartley P. Griffith an American Heart surgeon, performed first successful Transplant of a genetically modified pig heart to a 57 years old David Bennett Sr. He dies after two months.


                                                    Dr Dhaniram Baruah

Before  25 years of Bartley P. Griffith. On 1 January 1997 a Indian heart surgeon from  Assam  in India Dhaniram Baruah performed the world first heart transplant a pig’s heart in human body. The transplant was performed on Purna Saikia, worked for seven days.

The Golden River – Subansuri

             Gold rush or gold fever is a discovery of gold. Gold rushes happened at most of the continents. From Califorina , New South Wales so on. Myself talking about a river region where the gold rush occurred but not mentioned in the history books. Located in India a northeastern state name Arunachal Pradesh, a river name- Subansuri.



 Subansuri is called the River of gold. According to ancient mythology – the river beds composed of black sand, pebbles and boulder  and gold nuggets are extracted in traditional and old method. The word ‘subarna’ & ‘suri’ means gold & flow respectively. It is the biggest tributary of the mighty Brahamputra contributing 11% of its discharge. Originate from Tibetan Himalayas and makes its way to India via Arunachal Pradesh.

Now no more gold extraction took place where. But I m focusing on the natural beauty of this region in a brief scale. For adventurer, naturalist it is far better then gold. 

Main Bird in this region is Great Hornbill (Buceros bicoris)


Main animals in this region are Red Punda, Mithun( Bos frontalis)




Main tree of this region are Pine tree and Hollong (Disterocarpus retusus)


Main orchid is the Foxtail orchid (rhychostylis retusa)





Fish in this region are Tourt fish, Golden Mahseer (Tor putitora).





 Along the region of this river orchid, bird and animal sanctuary are situated. The lower half of the river is a delight for anglers, trekking and river rafting best time to visit March to June and September to November. The river was golden with gold in past but now golden with all natural beauties
