Getting started to flight.

Since childhood every people thinks to fly in the sky as the birds do.

Many years ago flying in the sky was such a dream that they can't do at that time.

A man trying to fly by attaching  a large wing 
From many centuries, humans have tried to fly just like the birds and have studied the flight of birds. Wings made of feathers or light weight wood have been attached to arms to test their ability to fly. The results were often disastrous as the muscles of the human arms are not like a birds and cannot move with the strength of a bird.



But after a lot of experiments human finds the way to fulfill their dreams by developing a unique thing by which the get success to touch the sky and we know that unique thing as "AEROPLANE".

                     This invention takes a great place to improve the humans society and now a stage came in  generation of human  being that people wants  explore the universe by going outside the earth. The people not only have desire but some of our intelligent scientists found the opportunity to explore universe and telling us about the world outside the earth....


  • Invention of  AEOLIPILE (a stream powered device)
Drawing of Aeolipile Created by Hero  Hero(or Heron of Alexandria was an ancient Greek mathematician and engineer worked with air pressure and steam to create source of power. 
      One experiment that he was developed was the aeolipile which used jets of stream to create rotary motion.The aeolipile consist of a vessel, usually such as a sphere or a cylinder, arranged to rotate on its axis, having opposite bent or curved (L-shaped) nozzles projecting from it. When the vessel is pressurized with steam , steam escaped through the nozzles which gave thrust sphere that caused it to rotate.
      The importance of the aeolipie is that it makes the start of engine invention.
