In "Pilgrim at Tinker Creek," Annie Dillard reflects on the phenomenon of shadows appearing blue when cast outdoors. She explains that this effect is due to the light from the blue sky rather than the yellow light of the sun. This observation prompts her to consider the nature of light and perception, emphasizing the interplay between environment and experience.
Moreover, Dillard highlights the vastness of the universe by mentioning the infinitesimal particles that contribute to the blue hue. This notion evokes a sense of wonder about the intricate details of our surroundings and the cosmic influences that shape even the simplest aspects of nature, like shadows.
