This fervent desire to know is the motivation behind all science, so we should not be surprised to find in Vedic India the beginnings of a potent scientific tradition. By the Christian era it would be in full flower: Indian mathematicians would have developed modern numerals, the decimal place system, zero, and basic algebra and trigonometry; surgeons would be performing operations as sophisticated as cataract surgery and caesarian section. But the roots of this scientific spirit are in the Vedas.
