The ancient Greeks made remarkable achievements in mathematics, astronomy and medicine. They tried to explain natural phenomena through reason instead of superstition.
古希腊人在数学、天文学、医学领域取得卓越成就。他们依靠理性而非迷信去解释自然现象。

    Mathematics 数学
    Euclid is the father of geometry. His great work Elements organized Greek geometrical knowledge into a complete logical system.
