At the outset let me start with the quote from the father of the theory of relativity, Albert Einstein who aptly remark that……
"We owe a lot to the Indians, who taught us how to count, without which no worthwhile scientific discovery could have been made."
Apart from Einstein Will Durant, American historian stated that
"India was the motherland of our race, and Sanskrit the mother of Europe's languages: she was the mother of our philosophy; mother, through the Arabs, of much of our mathematics; mother, through the Buddha, of the ideals embodied in Christianity; mother, through the village community, of self-government and democracy. Mother India is in many ways the mother of us all".
One of the essential features about the Vedic scene was the ambrosial amalgamation of the mind and the Mother Nature, achieved by our ancestral genius. This fusion was made possible by the sharp observation of the life in all forms by the sages of the yore. What helped them more in this exceptional contribution to the humanity was the lately lost faculty of lifting the mind to the ultimate spiritual level through meditation. From this spiritual height, the cause-effect relationship of natural phenomena, the intricate mechanism that guides and supports the organisms and the hopes, opportunities and threats that direct the forward progress of humanity etc. became crystal-clear to the visionary minds of our ancestors. Thus, in short, the Vedic knowledge was the creation of vision, insights, and observation and was tested in the biggest laboratory of them all, the Nature. Here my humble effort is towards the unveiling of the Vedic period of the Indian ancestry for an appreciation of its spectacular achievements in science. The ancient India of Vedic and ensuing eras gave the world many a legacy in mathematics, medicine, and natural sciences.
