So if you’re in the USA and you haven’t gotten your planetary postal stamps, you are missing out, friends.

In his classic tale Journey to the Center of the Earth, author Jules Verne dreamed of reaching the center of our planet through volcanic tubes. In the 1960s, scientists took up that challenge and tried to drill down into the earth’s mantle, but abandoned the project due to a lack of funding. Now, a team of scientists aboard the research vessel JOIDES Resolution is working to bore a hole deep into the Atlantis Bank in the Indian Ocean to collect samples of the crust and eventually break through into the mantle. Geologist Henry Dick, co-chief scientist of the expedition, joins Ira for an update on the progress of the project and explains what these samples could reveal about the formation of the planet.
Two jets colliding can form a chain-like fluid structure. With increasing flow rate, the rim of the chains becomes wavy and unstable, forming a fishbone structure where droplets extend outward from the fluid sheet via tiny ligaments. Eventually, the droplets break off in a pattern as beautiful as it is consistent. (Photo credits: A. Hasha and J. Bush)
