OCEAN CURRENT FLOWS AROUND THE MEDITERRANEAN SEA AND WESTERN ATLANTIC.

NASA time lapse simulation showing sea surface currents around western Europe. The visualization covers 11 months, from16 February ‘05 to 16 January ‘06. with each second in the video representing 2.75 days. The different colours represent current depths - white flows are nearest the surface, and darker colours running deeper.

Massive toxic spill in British Columbia pollutes streams and lakes. The Mount Polley Mine mines copper and gold. These mines require massive amounts of toxic acids to “eat” the rocks that contain the copper and gold. The waste is “contained” in a big retention pond (in this case a huge lake). The ponds just sit there with no plans for clean up. Humans are banned from the ponds. Governments say they are safe (despite that ponds fail on average of 30%).

Millions of tons of harmful metals, soils, and wastewater spilled into pristine habitat. Canada’s response? Whooppsy! ¯\_(ツ)_/¯.

An earthen dam at Mount Polley Mine in British Columbia breached on August 4, 2014, sending contaminated water surging into nearby lakes. Wastewater and metal-laden sand spilled from a retention basin and triggered a water-use ban in Likely, British Columbia, and other nearby towns. Local authorities had lifted the ban as of August 12.

On August 5, nearly all of the wastewater in the retention basin had drained, exposing the silty bottom. Hazeltine Creek, normally about 1 meter (3 feet) wide, swelled to a width of 150 meters (490 feet) as a result of the spill. In the aftermath of the flood, a layer of brown sediment coated forests and stream valleys affected by the spill. Notice how much forest immediately north of the retention basin was leveled. Debris, mainly downed trees, are visible floating on Quesnel Lake.

Mathematician Maryam Mirzakhani is the first woman to win a Fields Medal. It had been an all-boys club since the prizes were established in 1936.
Mirzakhani, a native of Iran, is a professor at Stanford University. She won for her work on “the dynamics and geometry of Riemann surfaces and their moduli spaces.”
Here’s how Nature summed up her contributions:

“Perhaps Maryam’s most important achievement is her work on dynamics,” says Curtis McMullen of Harvard University. Many natural problems in dynamics, such as the three-body problem of celestial mechanics (for example, interactions of the Sun, the Moon and Earth), have no exact mathematical solution. Mirzakhani found that in dynamical systems evolving in ways that twist and stretch their shape, the systems’ trajectories “are tightly constrained to follow algebraic laws”, says McMullen. He adds that Mirzakhani’s achievements “combine superb problem-solving ability, ambitious mathematical vision and fluency in many disciplines, which is unusual in the modern era, when considerable specialization is often required to reach the frontier”.


Erica Klarreich wrote a wonderful summary of Dr. Mirzakhani for Quanta magazine, which is worth a read. She’s apparently quite the generalist — deriving intellectual satisfaction in “crossing the imaginary boundaries people set up between different fields.” Among her diverse body of work outside dynamics is her doctoral dissertation on geodesics of hyperbolic surfaces, which another researcher called “the kind of mathematics you immediately recognize belongs in a textbook.” Meanwhile, she’s an unassuming character herself, with a deep love of her work and a phenomenal work ethic: “You have to spend some energy and effort to see the beauty of math.”

Wasted food is world's third-biggest carbon emitter after China and US: UN

ubuntuliberation:

The food the world wastes accounts for more greenhouse gas emissions than any country except for China and the United States, according to a United Nations report.

It says every year about a third of all food for human consumption, around 1.3 billion tonnes, is wasted, along with all the energy, water and chemicals needed to produce it and dispose of it.

Almost 30 per cent of the world’s farmland, and a volume of water equivalent to the annual discharge of Europe’s River Volga, are in effect being used in vain.
