Today, we remember this botanist and his discovery by calling the motion he observed Brownian motion.

今天，我们通过称他观察到的运动为布朗运动来纪念这位植物学家和他的发现。

In describing his work he made an analogy to Brownian motion, the jostling movement of pollen grains in water that was first observed down a microscope by Robert Brown, a botanist, in 1827.

在描述他的工作时，他将其比作布朗运动，1827年植物学家罗伯特·布朗（Robert Brown）首次在显微镜下观察到水中花粉颗粒的不规则碰撞运动。
