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.

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.
 Passage 2:Krul returned to Newcastle as backup to first choice Steve Harper. He made his senior league debut on 8 August 2009 in the opening Football League Championship game of the season away to West Bromwich Albion, coming on as a half time substitute for the injured Harper. Following this match, The Guardian called him "an excellent reserve goalkeeper". He later played the full Football League Cup match against Huddersfield Town on 26 August 2009, which Newcastle won 4–3. Krul also started the 2–0 League Cup defeat to Peterborough. Against Swansea City on 28 November, he again came on to replace the injured Steve Harper. On 2 January, he played in the FA Cup Third Round tie against Plymouth Argyle, the game ending 0–0. He then played in the replay at St James' Park on 13 January, a 3–0 victory. Krul started his first league game for Newcastle on 2 May 2010, the last day of the Championship campaign, against Queens Park Rangers at Loftus Road and kept a clean sheet. In July 2010, Krul signed a new four-year contract with Newcastle.
 Passage 3:In 1909, Alois Hitler Jr. met an Irishwoman by the name of Bridget Dowling at the Dublin Horse Show. They eloped to London and married on 3 June 1910. William Dowling, Bridget's father, threatened to have Alois arrested for kidnapping, but Bridget dissuaded him. The couple settled in Liverpool, where their son William Patrick Hitler was born in 1911. The family lived in a flat at 102 Upper Stanhope Street. The house was destroyed in the last German air-raid on Liverpool on 10 January 1942. Nothing remains of the house or those that surrounded it, and the area was eventually cleared and grassed over. Bridget Dowling's memoirs claim Hitler lived with them in Liverpool from 1912 to 1913 while he was on the run to avoid being conscripted in his native Austria-Hungary, but most historians dismiss this story as a fiction invented to make the book more appealing to publishers. Alois attempted to make money by running a small restaurant in Dale Street, a boarding house on Parliament Street and a hotel on Mount Pleasant, all of which failed. Alois Jr. left his family in May 1914 and he returned alone to the German Empire to establish himself in the safety-razor business.
