摘要

大约在1861年左右，一位名叫威廉·斯诺·哈里斯（William Snow Harris）的英国医生和电子研究员发表了一本薄薄的书，里面有三个实验。他的目标是帮助读者可视化电导率、电阻和闪电的强大影响。这本小册子的插图是用金箔印刷的，当读者在金属的一端充电时，电流会沿着阻力最小的路径烧焦一条黑色的路线。这本小册子是哈里斯数十年来说服英国皇家海军在木船上采用他的避雷针的努力的一部分。这幅插图显示了一个可怜的水手，他在闪电风暴中意外地被索具缠住了。正如哈里斯所写，如果没有避雷针，水手“很可能会被摧毁”。尽管在11艘舰艇上进行了成功的测试，包括贝格尔号（以达尔文而闻名），但海军部20多年来一直拒绝采用哈里斯的发明。

Past Forward: The Path of Most Resistance

In 1861 or thereabouts, a British doctor and electrical researcher named William Snow Harris published a slim volume containing three experiments. His goal was to help readers visualize conductivity, resistance, and the powerful effects of lightning. The booklet's illustrations were printed with gold leaf, and when the reader applied a charge to one end of the metal, the current would char a black course along the path of least resistance. The booklet was part of Harris's decades-long crusade to convince the Royal Navy to adopt his lightning rods on wooden ships. This illustration shows a poor seaman who accidentally gets caught in the rigging during a lightning storm. As Harris wrote, absent a lightning rod, the sailor “would be probably destroyed.” Despite successful tests on 11 vessels, including the HMS Beagle (of Darwin fame), the Admiralty resisted adopting Harris's invention for over 20 years.
