Bubble on Sand
Posted on July 22, 2014
On Cape Cod in Massachusetts this summer, we were fascinated with the bubbles that form after the waves break as the tide was receding. Some of these bubbles lasted thirty seconds or more, traveling along the thin layer of water that ebbed and swirled. I had bubbles on my mind, having recently read Lynn Margulis' 1999 book Symbiotic Planet about her theories on the mechanisms supporting the evolution of life from lifelessness, which included lipid bubbles that could have provided a natural container for various components to work together within.
