"Wonder is an essential survival skill." We walk past nature without giving it a second thought. Robert Macfarlane reminds us of the wonder behind a rainbow: "When you see a rainbow, you still stop. That's wonder. Rainbows are the charismatic megafauna of wonder. They do it often and well." "The other thing about a rainbow is it's utterly bespoke. It was no one else's rainbow, because it's a prismatic function: the water is lensing light and separating light into its constituent wavelengths. If you'd stepped a yard to the right and become a different person, you'd have seen a different rainbow. That's wondrous." "And science finesses the real into wonder. Science doesn't mean unweaving the rainbow. It can help us continue to be astonished by the world, just understand a little bit better how it works." "I don't see science and wonder as opposed."
