By combining massive amounts of diverse data, scientists from NASA and the Massachusetts Institute of Technology have created a beautiful high-resolution model of the Earth’s ocean currents.
The project, called Estimating the Circulation and Climate of the Ocean (ECCO), uses observational data—including ocean surface topography, surface wind stress, temperature, salinity profiles and velocity data—collected between June 2005 and December 2007. By incorporating these data into an M.I.T. model, the result is “realistic descriptions of how ocean circulation evolves over time,” according to the press release. “These model-data syntheses are among the largest computations of their kind ever undertaken.”
I’m mesmerized! :O

Freezing glass may shed light on a great mystery in mathematics
The way in which disorderly systems like glasses freeze could shed light on one of the greatest enigmas in mathematics today.
The mystery in question concerns prime numbers, which are essentially the elementary particles of arithmetic — a prime number such as 2 is divisible only by 1 and itself, while a composite number such as 4 is divisible by 1, 2 and 4.
One key tool for how prime numbers are distributed in the universe of numbers is theRiemann zeta function. A better understanding how the zeta function works could help mathematicians understand a mysterious pattern in how prime numbers seem to be distributed, upon which many theorems in math rest.
And now scientists are finding remarkable similarities between how disordered systems like glasses freeze and how prime numbers are distributed.
In glasses, atoms are freeze solid, arranged in a disorderly manner, while in crystals, they are arrayed in an orderly fashion. The way energy is distributed within disordered systems like glasses resembles a random landscape of hills and valleys. As the amount of energy within such a system is lowered, any travelers navigating this landscape would slow and eventually stop. The areas in which they would tend to freeze in place resemble the way numbers cluster with the Riemann zeta function.
And that means that a greater understanding of the process of freezing might help tackle one ofthe greatest unsolved problems in mathematics. The scientists detailed their findings online April 26 in the journal Physical Review Letters.

Ronald Van Der Meijs: Clouds of Knotted Sound
water-filled brass and bronze bowls on turntables. Watch a demo here.
The sound installation consists of two sound bowls. Because the two different sine waves are dueling with each other it creates nodes in the sound field that are audible and visible. These resonance areas can be observed in space by walking around the installation and can be observed with your ears. The visibility of the sound is created by the vibration patterns of the water in the bowls. The installation creates a sculpture of sound.
ed: I don’t even know what these things are, but they’re organized neatly.

My stamp arrived today! Along with a set of blank recycled cards. They are hand-cut with rounded corners using a traditional guillotine. Manufactured from 75% UK post consumer waste and 25% dung from the Sri Lankan elephant. The dung is collected, cleaned up and turned into pulp. The card itself it treated using non-chlorine methods to remove all bacteria, and is manufactured using the heritage steam-driven Fourdrinier machine, the worlds first mechanised paper-making machine dating back to 1895. Time to get stamping!
Still fundraising, as ever. Spread the word please people.

All of that can be done on a single iPad today….One last look at the Space Shuttle Endeavor’s cockpit before it was shut down forever and all I can think is wow…look at all those buttons.
