An insect like a wasp or a water strider can rest atop the water, held up by surface tension. This means that the cohesive force of the water molecules sticking to each other is stronger than the force of the bug being pushed down by gravity. This works because it spreads its weight out over a large surface area (like snowshoes). That creates a slight indentation in the top of the water, changing the direction that the light coming down is refracted and re-directing it slightly sideways (that’s where the bright halos around the dark areas come from). And what’s the absence of light?
Richard Feynman does his best to explain why science, in essence, is a form of art that may be much deeper and more philosophical than simple art itself. By no means am I calling art simple, but I will openly say I have much more respect and interest in scientists than artists, sorry artist friends.

“This 80-minute documentary focuses on the growing “wealth gap” in America, as seen through the eyes of filmmaker Jamie Johnson, a 27-year-old heir to the Johnson & Johnson pharmaceutical fortune. Johnson, who cut his film teeth at NYU and made the Emmy®-nominated 2003 HBO documentary Born Rich, here sets his sights on exploring the political, moral and emotional rationale that enables a tiny percentage of Americans – the one percent – to control nearly half the wealth of the entire United States. The film Includes interviews with Nicole Buffett, Bill Gates Sr., Adnan Khashoggi, Milton Friedman, Robert Reich, Ralph Nader and other luminaries.”
This is fantastic and I’ve always wanted someone to do a visualization of ocean currents like this. It’s like Van Gogh… from space. The Scientific Visualization Studio at NASA’s Goddard Space Flight Center created this mesmerizing animation called Perpetual Ocean which visualizes the ocean’s surface currents over a 30-month period between June 2005 and December 2007.
