Did You Know?
- The concept of zero was not just a number but a philosophical breakthrough representing "nothingness" or "void" (Shunya) in Indian thought.
- Ancient Indian surgeons performed cataract surgery using a technique called "couching" over 2,600 years ago, centuries before it appeared elsewhere.
- The Iron Pillar of Delhi, standing rust-free for over 1,600 years, contains 99.72% pure iron - a metallurgical feat unmatched even today.
- Chess pieces originally represented the four divisions of the Indian army: infantry (pawns), cavalry (knights), elephants (bishops), and chariots (rooks).
