Magnetic fields frozen into meteorite grains tell shocking tale of solar system birth The most accurate laboratory measurements yet made of magnetic fields trapped in grains within a primitive meteorite are providing important clues to how the early solar system evolved. The measurements point to shock waves traveling through the cloud of dusty gas around the newborn Sun as a major factor in solar system formation. “The measurements made by Roger Fu of MIT and Benjamin Weiss, also of MIT, are astounding and unprecedented,” said Steve Desch of Arizona State University. “Not only have they measured tiny magnetic fields thousands of times weaker than a compass feels, they have mapped the magnetic fields’ variation recorded by the meteorite, millimeter by millimeter.” Construction debris It may seem all but impossible to determine how the solar system formed, given it happened about 4.5 billion years ago. Among the most useful pieces of debris are the oldest, most primitive, and least altered type of meteorites called the chondrites.

An imaginary city that changed the twentieth century Yes, it does. It's very weird that a captain of industry like Gillette would come up with such socialist-sounding ideals. You'll note he was a member of this little socialist nutjob group before he caught a clue and successfully marketed the safety razor. It surprises me how people use things like game theory and mathematical theorems to "prove" that the private ownership of the means of production is a bad thing. 1. 2. 3. Nash totally ignores this, like most socialists do, because if they showed any understanding of how people really act then they'd realize how stupid a one size fits all solution is to any problem.
Three Chinese Leaders: Mao Zedong, Zhou Enlai, and Deng Xiaoping Mao Zedong Mao Zedong (1893-1976) was one of the historic figures of the twentieth century. A founder of the CCP (Chinese Communist Party), he played a major role in the establishment of the Red Army and the development of a defensible base area in Jiangxi province during the late 1920s and early 1930s. He consolidated his rule over the Party in the years after the Long March and directed overall strategy during the Sino-Japanese War and the civil war. Following the establishment of the PRC (People's Republic of China) in 1949, Mao was responsible for many of the political initiatives that transformed the face of China. During the early 1960s, Mao continued his restless challenge of what he perceived as new forms of domination (in his words, "revisionism," or "capitalist restoration"). In 1969 Mao designated Defense Minister Lin Biao, a Cultural Revolution ally, as his heir apparent. From Focus on Asian Studies, Vol.
Strays Online - A fantasy webcomic Changing Channel characteristsics Width and depth are simple variables and generally increase downstream as more water is added from tributaries. Width can be derived either from the water surface width (occupied channel width) or from measuring from bank to bank, giving the bank full width. We can calculate the stream order from source to mouth too, and this gives us an indication of the size and shape of river channels. The stream order is calculated as follows; Stream order 1 streams have NO tributaries feeding into them, they are the original streams that start at springs up in the source. Stream order 2 streams occur where two stream order 1 rivers come together at a confluence Stream order 3 streams occur where two stream order 2 rivers come together at a confluence (not a stream order 2 with a 1, it must be the SAME stream order meeting) The stream order continues like this. Wetted Perimeter is the measure of how much water contact there is with the bed and the banks of a river. Source
A closer look at communities thriving in unexpected places In Caracas, the capital of Venezuela, nearly 70 percent of the population lives in slums that appear to drape like silk over every hill of the city. Iwan Baan: Ingenious homes in unexpected placesIwan Baan is not as interested in what architects build as he is in the beautiful ways that people appropriate the spaces once the planners are gone. In today’s talk, Baan — whose breathtaking image of lower Manhattan after Hurricane Sandy hangs on at least one of our walls — shows incredible images from communities thriving in ways that seem quite opposite to the uniformity of suburbs. Baan’s talk will have you marveling at human ingenuity. In the center of Caracas is the Torre David, a 45-story unfinished office tower that was in the midst of construction until the developer died in 1993, followed by the crash of the Venezuelan economy the following year. With no lifts or escalators, the tower is essentially a forty-five-story walk up. In Makoko, forced evictions are a daily reality.
The internet is awesome-Chinese history in film version – Frog in a Well China British Pathé has put some 80,000 of their old newsreels on YouTube. This is a massive treasure trove of cool stuff, and the many hours I will spend looking at them are fully justified as "work". A lot the commentary is bland, foreigner-centered and uninformed, but the pictures are great. Civil War in China. (1922) Not much analysis, but a a nice funeral. Some of these are listed as unknown material with no date. such as. World Faces Crisis As Japan And China Clash In Far East (1938) I suppose I should comment and tell them what this is. Maybe Village Children Of South China (1951) is more your style?
Goblins Futurology: The tricky art of knowing what will happen next 23 December 2010Last updated at 02:38 By Finlo Rohrer BBC News Magazine Cheap air travel was among the predictions (illustration from Geoffrey Hoyle's book) A 1972 book which predicts what life would be like in 2010 has been reprinted after attracting a cult following, but how hard is it to tell the future? Geoffrey Hoyle is often asked why he predicted everybody would be wearing jumpsuits by 2010. These colourful ideas from his 1972 children's book, 2010: Living in the Future, helped prompt a Facebook campaign to track him down. "I've been criticised because I said people [would] wear jumpsuits," explains Hoyle, the son of noted astronomer and science fiction author Fred Hoyle. Hoyle's book is a product of its time. Fortunately, jumpsuit proliferation has not occurred as Hoyle predicted "Most of it is based on the evolution of a political system," Hoyle notes. The author also predicted widespread use of "vision phones" and doing your grocery shopping online. Continue reading the main story
Korean War The Korean War (25 June 1950 – 27 July 1953)[29][a][31] was a war between the Republic of Korea (South Korea), supported by the United Nations, and the Democratic People's Republic of Korea (North Korea), at one time supported by China and the Soviet Union. It was primarily the result of the political division of Korea by an agreement of the victorious Allies at the conclusion of the Pacific War at the end of World War II. The Korean Peninsula was ruled by the Empire of Japan from 1910 until the end of World War II. The failure to hold free elections throughout the Korean Peninsula in 1948 deepened the division between the two sides; the North established a communist government, while the South established a right-wing government. The U.S. provided 88% of the 341,000 international soldiers which aided South Korean forces, with twenty other countries of the United Nations offering assistance. Names In the U.S., the war was initially described by President Harry S. Background
Evidence of one of the universe's oldest stars discovered Astronomers using the Subaru Telescope on Mauna Kea, Hawaii say they have found the first ever evidence for the universe's first-generation of starsThe groundbreaking discovery was made in a second-generation starThe team found a chemical signature that must mean the younger star was made from one much olderIf correct, it would be the first evidence for such a stellar body ever foundFirst-generation stars ultimately gave rise to the planets, galaxies and other objects in the universe today By Jonathan O'Callaghan for MailOnline Published: 16:58 GMT, 22 August 2014 | Updated: 18:31 GMT, 22 August 2014 Astronomers have found the first ever evidence for the huge stars that are thought to have populated the early universe. With a mass many hundred times that of the sun, they would have lived very short lives and none are still in existence today. However traces of one has now been found, and the potentially groundbreaking discovery could yield fascinating information about the early universe.
