What we gifted to the world....
Innivations of India which are under rated by the world.
Zero - Mathematics does not make sense without 0. Although it has no value, it plays a vital role in Arithmetic. He was a great mathematician and an ace astronomer.

High quality steel was produced in South India since ancient times. The tech used to manufacture it was later on called the crucible technique. wrought iron 1st put with glass and charcoal in a container and was heated till the metal melted and absorbed carbon
India was the first nation to have a dock that dated back to 2400BCE. People belonging to the Harappa Civilization were the first to build a dock in Lothal. This proves their immense understanding of oceanology and marine engineering.
Diamonds were first mined in India. Huge deposits of diamonds were found in Central India and it gradually developed as a precious stone. India till 18th century was the only country where diamonds were found and were later on exported to other countries.
Leprosy was first noticed by Indians and various ancient remedies are also mentioned in the Atharva Veda. Lithiasis treatment or the treatment for eradicating stones was first introduced in India.
Cataract surgery and plastic surgery were also first performed by the ancient physician Sushruta. These surgeries dated back to 2000BCE and his work were later translated to Arabic language and gradually passed on to European countries.
wool, cotton originated from India. Evidences show that people of the Indus Valley used cotton and India pioneered the art of cotton spinning and used it in making fabric. Jute, a plant fiber, was cultivated in India since ancient times.
Buttons are a major part of our clothing even today. Buttons were invented in India and various historical evidences and excavations prove that buttons were used by the people belonging to the Indus Valley Civilization.
Cotton Gin is a machine used to separate cotton from the seeds. The evidence of this machine was found through the carvings on Ajanta caves where the pictures of these machines were engraved. Dating back to 500 AD, this hand roller machine was locally called Charkha.

Now let's talk about Rust free Iron pillars/beams which are approx 1000-2600 year old and even today rust free.
Its amazing and wonder in the field of metallurgy.
Iron gets easily oxidized https://t.co/7nxpZUuCX7 pic.twitter.com/LIXmLygaRP

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.

Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.
...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.
Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.
