Third , it is this " moment " of the segment of space - time which based on the the philosophy of the nature and describing the mechanical movement that symbolize the transform from the view of integralization in classical atomism of mathematics to the view of integralization of modern real number 另外，正是基于新的自然哲学的、作为描述机械运动的时空片段的“瞬”标志着古典数学原子论的积分观向现代的分割实数连续统的积分观的转化，而现代数学的微分概念更是直接源于描述机械运动的速度和与运动轨迹密切相关的曲线的切线问题。
