Catching Solar Waves
Kelvin-Helmholtz instabilities occur when two fluids of different densities or different speeds flow by each other. In the case of ocean waves, that's the dense water and the lighter air. As they flow past each other, slight ripples can be quickly amplified into the giant waves loved by surfers. In the case of the solar atmosphere, which is made of a very hot and electrically charged gas called plasma, the two flows come from an expanse of plasma erupting off the sun's surface as it passes by pl
Africa's Disease Burden
LSE Health and the LSE Africa Initiative in collaboration with The British Academy invites you to an event on Africa’s disease burden. Chronic non-communicable diseases have become major causes of adult disability and death in Sub-Saharan Africa. Chronic disease deaths in men and women as a whole are higher in sub-Saharan African than in virtually all other regions of the world and co-exist with a high burden of infectious diseases. In advance of the UN’s High Level Meeting on chronic non-co
Oklahoma Flag and Anthem The Oklahoma state flag honors more than 60 groups of Native Americans and their ancestors. The blue field comes from a flag carried by Choctaw soldiers during the civil war. The center shield is the battle shield of an Osage warrior. It is made of buffalo hide and decorated with eagle feathers. Two symbols of peace lie across the shield. One is the calumet, or peace pipe. The other is an olive branch. Crosses on the shield are Native

Learn About a More Complicated Friction/Inclined Plane Problem
Khan Academy Presents: Fun with two masses, some wire, a pulley, and a ramp with friction. (10:15) Sal Khan uses computer software and different colors for demonstration.
Plate tectonics is an earth sciences topic that attracts a good deal of interest, given that it a topic very often featured in popular science programmes on TV and radio. It is a subject that have strong visual appeal. The coverage is S279 is self-contained, up to date and is written in a way that will be accessible to those with interest and motivation, all the more so for those who have some pre-existing scientific understanding.
Where the Shape of the Egg Comes From?
The shape of the egg is postulated to be the consequence of opposing forces relative to the location of perspective of points that define the spaces of its' contents. For example, net velocities of motion of light emitted in two planes plus the velocity of motion of its' source would be expected to be decreased in the case when the direction of the light beam is opposed to the direction of motion to cause the blunt edge and increased when it aligns with the direction of motion of its' source t

"We No Longer Control Our Resources": Donna Koons Kingsley Describes the Struggle of Trinidad's Oilf
A slew of international financial crises in the early 1990's, including collapses in Mexico, Southeast Asia, and Russia, highlighted the important influence international lending organizations such as the International Monetary Fund (IMF) and the World Bank had over economic decisions in the developing world. Often in cooperation with local elites, these bodies have forced countries to respond to debt crises by privatizing public industries and utilities, in many cases selling these public resou
"The Momentum Was Catching On:" Lillian Roberts Describes Organizing Hospital Workers in New York Ci
Municipal workers led a wave of strikes that made the 1960's and early 1970's a highpoint for organized labor militancy in New York City. Teachers, social workers, sanitation workers, and parks employees all fought to improve work conditions, low-paying wage scales, and to reform the city's social services. Lillian Roberts arrived in New York in 1965 to organize low-paid and often disrespected hospital workers for American Federation of State, County, and Municipal Employees (AFSCME). At the tim
Chlorine Nitrate over the Arctic from CLAES (2-12-93 - 3-16-93)
Key to understanding the chlorine chemistry in the polar stratosphere is the measurement of polar stratospheric clouds, chlorine monoxide, and the reservoir gas chlorine nitrate. Chlorine nitrate has been measured by the Cryogen Limb Array Etalon Spectrometer, CLAES. CLAES makes measurements by looking at infrared emission from cloud particles and trace gases. CLAES measurements help to show that the polar stratospheric clouds which form in the cold Arctic stratosphere have converted most of the

Tower of Babylon - Plastic Palace
Watch two of America's most commonly consumed plastic items—hangers and bottles—get repurposed, designed, and transformed into large-scale works of art by students at Georgia Tech's College of Architecture. The purpose? To help build awareness about sustainability and to creatively convey the astronomical volume of recyclable material we carelessly dispose of everyday.
