Q: Passage: The first obelisks may start to appear in the later 16th century and it is suggested that the obelisk on Compton Pike is Elizabethan in date. More securely dated is a series of obelisks which start to appear in the 18th century. The first of these was the Wakeman obelisk of 1702 by Nicholas Hawksmoor, which is set in the square at Richmond, Yorkshire. Probably several hundred obelisks exist in the British Isles dating from 18th and early 19th centuries. Most of these obelisks, which are often landmarks commemorate famous people and their achievements. At Stowe in Buckinghamshire an obelisk was erected in memory of Wolfe's victory at Quebec in 1752, while at the death of the Duke of Cumberland in 1765 was noted by an obelisk at Englefield Green in Surrey. Thomas Coke, Earl of Leicester, Coke of Norfolk the farming pioneer has a particularly fine obelisk, set up in the park he created at Holkham in Norfolk. Sometimes an obelisk was used to mark the site of a battle such as the obelisk on the site of English Civil War battlefield at Naseby in Leicestershire. Occasionally obelisks are used as mile markers, as on the Great North Road at a mile from Westminster. In Lincoln an elaborate obelisk was set up on the High Bridge in 1762–63 as a conduit for dispensing water, while Anthony Salvin used obelisks as water fountains on the Belton House estates in Lincolnshire.

He graduated from the University of Iowa with Ph.D. in 1948 with thesis The polarizability of the meson-charge cloud of a neutron in an external electrostatic field. He was from 1948 to 1949 an Atomic Energy Commission (AEC) Fellow at the Institute for Advanced Study and from 1949 to 1951 an AEC Fellow at the Berkeley Radiation Laboratory. He was from 1951 to 1954 an assistant professor of physics at Indiana University and from 1954 to 1957 an associate professor of physics at the University of Wisconsin, Madison. In 1953 he was elected a fellow of the American Physical Society. From 1957 to 1981 he was a staff member of Lawrence Berkeley National Laboratory, as well as a professor of physics at the University of California, Berkeley. In 1974 he was elected a member of the National Academy of Sciences. From 1981 to 1991 he was the director of the Marine Physical Laboratory, Scripps Institute of Oceanography, as well as a professor of physical oceanography at the University of California, San Diego. In 1991 he retired as professor emeritus. His doctoral students include Shang-keng Ma.
 Link Information: Lawrence Berkeley National Laboratory (LBNL), commonly referred to as Berkeley Lab, is a United States national laboratory that conducts scientific research on behalf of the United States Department of Energy (DOE).

Q: Passage: Time Air was a regional airline that initiated operations in Lethbridge. Founded in 1966 as Lethbridge Air Service, Time Air flew a variety of turboprop aircraft and also operated jet service as well with Fokker F28 Fellowship twin jets. In February 1976, the Official Airline Guide (OAG) listed up to eight round trip flights a day operated by Time Air nonstop between Lethbridge and Calgary with Fokker F27 Friendship and de Havilland Twin Otter turboprops. According to the November 15, 1979 edition of the OAG, Time Air was operating up to ten flights a day nonstop to Calgary with DHC-6 Twin Otter and Short 330 turboprop aircraft. By April 1985, the airline was operating larger Dash 7 turboprops on the Lethbridge-Calgary route in addition to the Short 330 aircraft with up to nine flights a day. In 1995, Time Air was flying the Fokker F28 twin jet on a daily basis between Calgary and Lethbridge in addition to other flights operated on the route with Dash 8 turboprops. This appears to have been one of the few times that Lethbridge had scheduled passenger jet service. Time Air was also flying at this time as a Canadian Partner air carrier as part of a code sharing agreement with Canadian Airlines International (formerly CP Air). There was also competition on the Lethbridge-Calgary route at this time as Air BC was operating Dash 8 turboprops as an Air Canada Connector air carrier via a code sharing agreement with Air Canada. Air BC also operated British Aerospace BAe Jetstream 31 between Lethbridge and Calgary at one point. Time Air operated other flights as well from Lethbridge including direct service to Vancouver via an intermediate stop in either Kelowna or Penticton, British Columbia during the 1980s and also nonstop service in 1988 to Great Falls, Montana. In 1993, Time Air and Ontario Express began operating as Canadian Regional Airlines on behalf of Canadian Airlines International which then eventually acquired Time Air and merged the airline with Ontario Express. By 1999, Time Air was operating Dash 8 turboprops as well as Fairchild Swearingen Metroliner on its flights to Calgary as Canadian Regional while Alberta Citylink was flying BAe Jetstream 31 turboprops on its services to Calgary as Air Canada Connector.
