Passage: Both Sui and Tang empires occupied the same location. In 582, Emperor Wen of the Sui dynasty sited a new region southeast of the much ruined Han Dynasty Chang'an to build his new capital, which he called Daxing (大興, “Great Prosperity”). Daxing was renamed Chang'an in year 618 when the Duke of Tang, Li Yuan, proclaimed himself the Emperor Gaozu of Tang. Chang'an during the Tang dynasty (618–907) was, along with Constantinople (Istanbul) and Baghdad, one of the largest cities in the world. It was a cosmopolitan urban center with considerable foreign populations from other parts of Asia and beyond. This new Chang'an was laid out on a north-south axis in a grid pattern, dividing the enclosure into 108 wards and featuring two large marketplaces, in the east and west respectively. Everyday, administrators of the two marketplaces would beat gong for three hundred times in the morning and evening to signify the start and stop of business. People lived in the wards were not allowed to go outside after curfew. Officials with higher-ranking had the privilege to live closer to the central avenue. Chang'an's layout influenced city planning of several other Asian capitals for many years to come. Chang'an's walled and gated wards were much larger than conventional city blocks seen in modern cities, as the smallest ward had a surface area of 68 acres and the largest ward had a surface area of . The height of the walls enclosing each ward were on average 9 to in height. The Japanese built their ancient capitals, Heijō-kyō (today's Nara) and later Heian-kyō or Kyoto, modelled after Chang'an in a more modest scale yet was never fortified. The modern Kyoto still retains some characteristics of Sui-Tang Chang'an. Similarly, the Korean Silla dynasty modeled their capital of Gyeongju after the Chinese capital. Sanggyeong, one of the five capitals of the state of Balhae, was also laid out like Chang'an.

Passage: Wasson was born Isabel Deming Bassett in Brooklyn, NY on January 11, 1897, daughter of urban planner Edward Bassett and Annie Preston Bassett, and sister of inventor and engineer Preston Bassett. Wasson graduated Phi Beta Kappa from Wellesley College in 1918, majoring in history so she could take a wide range of science courses. She took classes in geology after graduation at the University of Chicago and the Massachusetts Institute of Technology. She met her future husband, petroleum geologist Theron Wasson, whom she married in 1920, while working towards a master's degree in geology at Columbia University, which she finished in 1934. They had three children: Elizabeth W. Bergstrom, a biologist; Edward B. Wasson, a petroleum geologist; and Anne Harney Gallagher, an art historian. Wasson worked as a petroleum geologist in her husband's office at the Pure Oil Company from the early 1920s until 1928. She published two scholarly articles on geology, one co-authored with her husband about an oil field discovered by Pure Oil in 1914, and another by herself about the ages of rock formations in Ohio and new terminology for them; the latter was cited in a number of other papers and a recent book. After 1928 she spent over 50 years in River Forest, IL, teaching science in the local public schools, lecturing, bird watching (ornithology), and mentoring generations of young naturalists. She was quoted in this 1986 Chicago Tribune article as an expert on local geology at age 89. She was honored for her contributions to local history in 1982 when the Wasson Room was named after her in a local school to hold local history resources. Her interests included archaeology; she discovered a Native American religious mound in Thatcher Woods, near her house in River Forest, in the 1930s. An article about her discovery called her "the one who started the environmental education movement in America back in the 1920s and '30s." Theron and Isabel divorced in 1953 and she did not remarry. From 1953-1954, Wasson served as President of the Chicago Ornithological Society. Wasson also taught classes at the Morton Arboretum in Lisle, Illinois. She died in La Grange Park, IL, in 1994.

Passage: Soon after the start of World War II, it was proposed to convert the four prototypes to long-range maritime patrol aircraft. V2 underwent a trial modification. It was fitted with an extended nose section with extensive glazing (like the Heinkel He 111 H-6), defensive armament (a 7.92 mm/.312 in MG 15 machine gun in the nose, twin-beam positions, a ventral cupola, and a powered dorsal turret), a compartment for ordnance in the fuselage, and navigation and military radio equipment. The company had by now been renamed as the Blohm & Voss aircraft division so the converted aircraft was redesignated the BV 142 V2/U1 while the V1 was similarly converted. Both were used operationally from late 1940 and were posted to the Luftwaffes second surveillance Group. This unit was assigned to the operations staff of Luftflotte III in France. However, their performance was disappointing, and after only a few missions they were withdrawn from service in 1942. Aircraft V3 and V4 were used as transport aircraft for the occupation of Denmark and in the Norway campaign with the KGr.z.b.V. 105 (Special combat team) and could transport 30 fully equipped soldiers over 4,000 km (2,490 mi). The ultimate fate of V3 and V4 is unknown. It was later planned to use the V1 and V2 to carry the Henschel GT 1200C guided torpedo, but the plan was cancelled.
