对于布朗运动之误解[编辑]
值得注意的是，布朗运动指的是花粉迸出的微粒的随机运动，而不是分子的随机运动。
但是通过布朗运动的现象可以间接证明分子的无规则运动。
一般而言，花粉之直径分布于30～50μm、最小亦有10μm之谱，相较之下，水分子直径
约0.3nm（非球形，故依部位而有些许差异。），略为花粉的十万分之一。因此，花粉
难以产生不规则振动，事实上花粉几乎不受布朗运动之影响。在罗伯特·布朗的手稿中
，“tiny particles from the pollen grains of flowers”意味着“自花粉粒中迸出
之微粒子”，而非指花粉本身。然而在翻译为诸国语言时，时常受到误解，以为是“水
中的花粉受布朗运动而呈现不规则运动”。积非成是之下，在大众一般观念中，此误会
已然根深蒂固。
在日本，以鹤田宪次‘物理学丛话’为滥觞，岩波书店‘岩波理科辞典’[3]、花轮重
