And man made a thing for him, which we call submarine today. So in today's video we will learn in detail about how the submarine was invented? Who made the first submarine and how was it made? How did that submarine work? Then when was the submarine built for the first time in our India? Which country currently has the world's largest submarine?

So for the first time in history the British scientist who proposed the idea of a submarine was William Bourne. He published a book in the year 1578, whose name was "Inventions or Devices". In this book, he proposed the design of a boat that could dive and walk under water. That is, he had told about the design of the submarine, this is the oldest record with a submarine, there is no older record than this. So 42 years after this book was published in 1578, in the year 1620, Cornelis Drebbel, a Dutch physicist living in the United Kingdom, read the book "Inventions or Devices" written by William Bourne, So after reading this book Cornelis Drebbel got the idea to turn William Bourne's theory into reality. James I was the king of England at that time, so Cornelis Drebbel went to his king and after getting his support, Cornelis Drebbel quickly built a small boat. http://bit.ly/3qvkSzu http://apple.co/3vedIDj
