The top photo is Dr. Walter Tschnickel with a cast of a Florida harvest ant’s nest. The illustration below is that of a jellyfish on the right-hand side. The left side is a diagram of the shapes made by drops of ink in water. This correlation and illustration comes to us from D’Arcy Wentworth Thompson. I saw the cast of the ant nest on my tumblr dash just now and immediately thought of Thompson’s jellyfish.

From a distance it looks rather like a big rusty metal box but closer inspection reveals a homemade armored vehicle waiting to be deployed. Sham II, named after ancient Syria, is built from the chassis of a car and touted by rebels as “100 percent made in Syria.” (Herve Bar/AFP/Getty Images)
