Out of the total of 1131 branches of Vedas which have originated, there are only 7 branches that are available and studied. All the other branches vanished with time. And within the same, the noted Yajurveda which is supposedly known to depict the factual modern science that we know today, had 101 branches out of which only 4 are studied today, that too of Krsna Yajurveda.
Astronomy, Geography, Constellation science, Botany and Animal science; Varahamihr (499 - 587 CE) was another eminent astronomer. In his book, Panschsiddhant, he noted that the moon and planets shine due to the sun. Many of his other contributions captured in his books Bruhad Samhita and Bruhad Jatak, were in the fields of geography, constellation science, botany and animal science. For example he presented cures for various diseases of plants and trees.
Knowledge of botany (Vrksh-Ayurveda) dates back more than 5,000 years, discussed in India's Rig Veda. Sage Parashara (100 BCE) is called the "father of botany" because he classified flowering plants into various families, nearly 2,000 years before Lannaeus (the modern father of taxonomy). Parashara described plant cells - the outer and inner walls, sap color-matter and something not visible to the eye - anvasva. Nearly 2,000 years -later Robert Hooke, using a microscope described the outer and inner wall and sap color-matter.
Metallurgy; India was the world-leader in Metallurgy for more than 5,000 years. Gold jewellery is available from 3,000 BCE. Brass and bronze pieces are dated back to 1,300 BCE. Extraction of zinc from ore by distillation was used in India as early as 400 BCE while European William Campion patented the process some 2,000 years later. Copper statues can be dated back to 500 CE. There is an iron pillar in Delhi dating back to 400 CE that shows no sign of rust or decay.
Cosmology and Psychology; According to India's ancient texts, around 3000 BCE sage Kapil founded both cosmology and psychology. He shed light on the Soul, the subtle elements of matter and creation. His main idea was that essential nature (prakrti) comes from the eternal (purusha) to develop all of creation. No deeper a view of the cosmos has ever been developed. Further, his philosophy of Sankhya philosophy also covered the secret levels of the psyche, including mind, intellect and ego, and how they relate to the Soul or Atma.
