Radio/Wireless communication
Radio/Wireless communication
We all know that Marconi received a Nobel Prize in Physics in
1909 for contribution to the development of wireless telegraphy.
But the first public demonstration of radio waves for communication
was made by Sir Jagdish Chandra Bose in 1895, two years prior to
Marconis similar demonstration in England.
Sir Bose was posthumously credited (more than a century later)
for his achievement. The fact remains that this discovery truly
shaped the face of modern wireless communication.
Steel & Metal works
Ancient Indians were pioneers in metallurgy. High quality steel
was produced, almost two thousand years before it was understood by
the West. One of the most remarkable feat in metallurgy: creating a
seamless celestial globe, was invented in Kashmir. It was earlier
considered impossible to create a metal globe without seams.
Ink
Many ancient cultures and civilizations independently discovered
and prepared ink for writing purposes. The source of carbon pigment
used in Indian Ink (called musi) used in ancient India, was India.
Since 4th century BC, the practice of writing with ink with a sharp
pointed needle was common in South India.
Diamond Mining
Worldwide, India was the only source of diamonds until the
discovery of mines in Brazil in the 18th century. Almost 5000 years
ago, diamonds were first recognized and mined in central India.
Cataract Surgery
Indian physician Sushruta (6th century BCE) had the knowledge of
performing cataract surgery. It spread to China from India. Greek
scientists would visit India to get operations done and also to
learn the nitty-gritties.
