It is true that many discoveries and inventions have been made in India throughout history, but it is also true that these contributions have not always been widely recognized or acknowledged by the world. One example of this is the discovery that the Earth revolves around the sun, which is often attributed to Nicolaus Copernicus. However, it is believed that this discovery was first made by the Indian mathematician and astronomer Aryabhata in the 5th century.
There are several reasons why the contributions of ancient Indian scientists and scholars have not always been widely recognized or acknowledged. One reason is that during the time when many of these discoveries were made, India was ruled by foreign powers, such as the British, and the contributions of Indians were often overlooked or attributed to the colonizers. Additionally, many of the scientific texts and manuscripts from ancient India were lost or destroyed over time, making it difficult to trace the origins of certain discoveries. Furthermore, European scholars in the past had a tendency to view non-European cultures as being inferior and therefore may not have given credit where credit was due.
Another reason is the language barrier. Most of the ancient Indian scientific texts were written in Sanskrit, which is a language not widely spoken or understood outside of India. This made it difficult for European scholars to access and study these texts, and as a result, many of their contributions went unrecognized. Furthermore, there were also challenges in terms of translation as the scientific terms and concepts used in ancient Indian texts were different from those used in Europe, and many translators were not familiar with the technical vocabulary.
The lack of acknowledgement of ancient Indian contributions is also rooted in the fact that India did not have a strong tradition of scientific publication and dissemination, unlike the European countries. European scientists had established institutions and societies dedicated to the promotion and dissemination of scientific knowledge, which helped to disseminate and popularize their works. In contrast, Indian scholars and scientists often kept their works private and did not publish them widely.
Another reason is that the Western world has been the dominant force in shaping the narrative of science and technology and has been able to disseminate it globally. Also, the west has been able to influence the way in which scientific knowledge is being studied, taught, and researched. This has led to the overwhelming emphasis on the contributions of Western scientists in the history of science and technology.
In conclusion, there are several reasons why the contributions of ancient Indian scientists and scholars have not always been widely recognized or acknowledged by the world. The colonization of India, the loss of texts and manuscripts, language barriers, the lack of scientific dissemination and publication, and the dominance of the Western narrative have all contributed to the under-representation of Indian contributions in the history of science and technology. Today, however, there is ongoing effort to acknowledge and recognize the contributions of ancient Indian scientists and scholars, and to make their works more widely known and studied.
