Marshall Island Stick Charts and Embodied Mathematics
There were two things I found most interesting about the article on the Marshall Island stick charts. The first was how detailed and ingenious the charts were, and how skilled the navigators were who used them. It’s a testament to human adaptability and intellect that the Marshallese people were able to use their observations of their environment to discover scientific facts about wave refraction, reflection, and interference, and to put this knowledge to work navigating their environment. I was particularly struck by the section which described how navigators would train lying in different parts of the water around their atolls in order to get a kinaesthetic sense for the structures on their mattang (stick charts mapping wave interactions with other waves and landmasses), and have such a fine-tuned awareness of the feeling of the waves that they could determine where they were on their mattang just by lying in the bottom of their boats and feeling the waves. I was also surprised ...
