Title: The Evolution of Technology in Ancient India Ancient India was a hub of technological advancements that shaped the course of history. From the invention of the decimal system to the development of metallurgy, Indian civilizations were at the forefront of innovation. One of the most significant contributions was the invention of the number zero by mathematicians in the 5th century CE. This revolutionary concept laid the foundation for modern mathematics and science. The field of medicine also saw remarkable progress in ancient India. The Ayurvedic system of medicine, which originated around 1500 BCE, emphasized the use of natural remedies and surgical techniques. Sushruta, often regarded as the "Father of Surgery," conducted complex surgeries including cataract removal and plastic surgery using rudimentary tools. Indian craftsmanship in metallurgy was highly advanced, with the production of high-quality steel known as Wootz steel. This steel was used to create the legendary Damascus swords, renowned for their strength and sharpness. The intricate designs of Indian jewelry and sculptures also showcased the mastery of metallurgical techniques. Furthermore, India's architectural marvels such as the Ajanta and Ellora caves and the temples of Khajuraho stand as a testament to the engineering prowess of ancient Indian builders. The precise alignment of structures, intricate carvings, and use of advanced acoustics demonstrate a deep understanding of architecture and design
