Vedic Mathematics
The numbers don't lie. Ancient Indian mathematicians produced results that modern instruments verify to within fractions of a percent. Zero, gravity, calculus, the sidereal day — all discovered in India, centuries before their “official” Western counterparts.

The Accuracy Table
Side-by-side comparison of ancient Indian calculations vs modern measured values. Pi, sidereal day, Earth's circumference, planetary diameters, precession of equinoxes, speed of light.
Aryabhata
476–550 CE · Kusumapura
At age 23, wrote the Aryabhatiya — correctly explaining Earth's rotation, calculating Pi to 4 decimal places, computing the sidereal day within 0.01 seconds, and explaining eclipses as geometric shadows.
Brahmagupta
598–668 CE · Bhinmal, Rajasthan
Defined zero as a number with complete arithmetic rules. Described gravity as an attractive force of the Earth. Both discoveries predate their European counterparts by over 1,000 years.
Madhava & Kerala School
c. 1340–1425 CE · Kerala
Discovered infinite power series for Pi, sine, cosine, and arctangent — 250–300 years before Newton and Leibniz. Calculated Pi to 13 decimal places in c. 1400 CE. Founded systematic calculus.
