List of India’s great inventions and contributions
Steel:
It is India that invented steel. Indian steel was deemed the best in the world up until eighteenth century.
Most parts of India produced very fine iron and steel and around 1700-1800 it was perhaps the best steel in the world and distant countries like the Netherlands and Britain imported it and used it for special purposes.
The massive rust-free iron is erected in the Qutub Area of Delhi and was built by Chandra Gupta in 4th Century AD.
Textiles:
India produced the best textile products in the world until it was suppressed by the British, who wanted to sell their products in India.
Dockyard:
The earliest dockyard of the world is located at Lothal, a Harappan acropolis in Gujarat.
Zinc:
Zinc metal was smelted and extracted for the first time both in India and Greece in the mid-I millennium BC.
Planned city lay-outs:
The Indus Civilization was the first to lay out a planned layout of the towns of Mohenjodaro, Harappa, Kalibangan etc.
Raja Bhoja (1018-60 of Dhar -Malwa) who was himself a great engineer and was the architect of Bhojsagar - (one of the largest artificial irrigation lakes of medieval India) was a great patron of engineering projects. He commissioned a university (Bhoj Shala) at Dhar.
Viewing town planning as an important aspect of government, he provided a detailed network of roads connecting villages and towns in his magnum opus, Somarangana Sutradhara. In addition to a chapter on town planning, the Somarangana Sutradhara also included chapters on mechanical engineering, soil testing, orientation of buildings, the selection of building material, architectural styles, and the vertical and horizontal components of buildings.
The Somarangana Sutradhara also describes machines and mechanical devices such as chiming chronometers (putrika-nadiprabodhana), and in his Yuktikalpataru, Raja Bhoja also warned shipbuilders about using iron along the bottom of the vessels for this would render them vulnerable to magnetic rocks at sea.
