title: Muslim world
text: One of the common definitions for "Islamic philosophy" is "the style of philosophy produced within the framework of Islamic culture." Islamic philosophy, in this definition is neither necessarily concerned with religious issues, nor is exclusively produced by Muslims. The Persian scholar Ibn Sina (Avicenna) (980–1037) had more than 450 books attributed to him. His writings were concerned with various subjects, most notably philosophy and medicine. His medical textbook The Canon of Medicine was used as the standard text in European universities for centuries. He also wrote The Book of Healing, an influential scientific and philosophical encyclopedia.

title: Queen Zixi of Ix
text: Queen Zixi of Ix, or The Story of the Magic Cloak, is a children's book written by L. Frank Baum and illustrated by Frederick Richardson. It was originally serialized in the early 20th-century American children's magazine "St. Nicholas" from November 1904 to October 1905, and was published in book form later in 1905 by The Century Company. The events of the book alternate between Noland and Ix, two neighboring regions to the Land of Oz, and Baum himself commented this was the best book he had written. In a letter to his eldest son, Frank Joslyn Baum, he said it was "nearer to the "old-fashioned" fairy tale than anything I have yet accomplished," and in many respects, it adheres more closely to the fairy tale structure than the Oz books.

title: Tikki Tikki Tembo
text: Tikki Tikki Tembo is a 1968 picture book written by Arlene Mosel and illustrated by Blair Lent. The book tells the story of a Chinese boy with a long name who fell into a well. It is a sort of origin myth about why Chinese names are so short today. The book is controversial because it appears to retell a Japanese story and because it does not portray Chinese culture accurately.

title: 2008 Sichuan earthquake
text: Experts point out that the earthquake hit an area that has been largely neglected and untouched by China's economic rise. Health care is poor in inland areas such as Sichuan, highlighting the widening gap between prosperous urban dwellers and struggling rural people. Vice Minister of Health Gao Qiang told reporters in Beijing that the "public health care system in China is insufficient." The Vice Minister of Health also suggested that the government would pick up the costs of care to earthquake victims, many of whom have little or no insurance: "The government should be responsible for providing medical treatment to them," he said.

title: 2008 Sichuan earthquake
text: Reginald DesRoches, a professor of civil and environmental engineering at Georgia Tech, pointed out that the massive damage of properties and houses in the earthquake area was because China did not create an adequate seismic design code until after the devastating 1976 Tangshan earthquake. DesRoches said: "If the buildings were older and built prior to that 1976 earthquake, chances are they weren't built for adequate earthquake forces."

title: 2008 Sichuan earthquake
text: News reports indicate that the poorer, rural villages were hardest hit. Swaminathan Krishnan, assistant professor of civil engineering and geophysics at the California Institute of Technology said: "the earthquake occurred in the rural part of China. Presumably, many of the buildings were just built; they were not designed, so to speak." Swaminathan Krishnan further added: "There are very strong building codes in China, which take care of earthquake issues and seismic design issues. But many of these buildings presumably were quite old and probably were not built with any regulations overseeing them."

title: The Oregon Trail: Sketches of Prairie and Rocky-Mountain Life
text: The Oregon Trail: Sketches of Prairie and Rocky-Mountain Life (also published as The California & Oregon Trail) is a book written by Francis Parkman. It was originally serialized in twenty-one installments in "Knickerbocker's Magazine" (1847–49) and subsequently published as a book in 1849. The book is a first-person account of a 2-month summer tour in 1846 of the U.S. states of Nebraska, Wyoming, Colorado, and Kansas. Parkman was 23 at the time. The heart of the book covers the three weeks Parkman spent hunting buffalo with a band of Oglala Sioux.

title: 2008 Sichuan earthquake
text: As a result of the magnitude 7.9 earthquake and the many strong aftershocks, many rivers became blocked by large landslides, which resulted in the formation of "quake lakes" behind the blockages; these massive amounts of water were pooling up at a very high rate behind the natural landslide dams and it was feared that the blockages would eventually crumble under the weight of the ever-increasing water mass, potentially endangering the lives of millions of people living downstream. As of May 27, 2008, 34 lakes had formed due to earthquake debris blocking and damming rivers, and it was estimated that 28 of them were still of potential danger to the local people. Entire villages had to be evacuated because of the resultant flooding.

title: 2008 Sichuan earthquake
text: Malaysia-based Yazhou Zhoukan conducted an interview with former researcher at the China Seismological Bureau Geng Qingguo (耿庆国), in which Geng claimed that a confidential written report was sent to the State Seismological Bureau on April 30, 2008, warning about the possible occurrence of a significant earthquake in Ngawa Prefecture region of Sichuan around May 8, with a range of 10 days before or after the quake. Geng, while acknowledging that earthquake prediction was broadly considered problematic by the scientific community, believed that "the bigger the earthquake, the easier it is to predict." Geng had long attempted to establish a correlation between the occurrence of droughts and earthquakes; Premier Zhou Enlai reportedly took an interest in Geng's work. Geng's drought-earthquake correlation theory was first released in 1972, and said to have successfully predicted the 1975 Haicheng and 1976 Tangshan earthquakes. The same Yazhou Zhoukan article pointed out the inherent difficulties associated with predicting earthquakes. In response, an official with the Seismological Bureau stated that "earthquake prediction is widely acknowledged around the world to be difficult from a scientific standpoint." The official also denied that the Seismological Bureau had received reports predicting the earthquake.

title: Geology
text: Some modern scholars, such as Fielding H. Garrison, are of the opinion that the origin of the science of geology can be traced to Persia after the Muslim conquests had come to an end. Abu al-Rayhan al-Biruni (973–1048 CE) was one of the earliest Persian geologists, whose works included the earliest writings on the geology of India, hypothesizing that the Indian subcontinent was once a sea. Drawing from Greek and Indian scientific literature that were not destroyed by the Muslim conquests, the Persian scholar Ibn Sina (Avicenna, 981–1037) proposed detailed explanations for the formation of mountains, the origin of earthquakes, and other topics central to modern geology, which provided an essential foundation for the later development of the science. In China, the polymath Shen Kuo (1031–1095) formulated a hypothesis for the process of land formation: based on his observation of fossil animal shells in a geological stratum in a mountain hundreds of miles from the ocean, he inferred that the land was formed by erosion of the mountains and by deposition of silt.
