Question: Of the first two post-doc positions John Ellis held, which company did he work for the longest? Passage:After completing his secondary education at Highgate School, he attended King's College, Cambridge, earning his PhD in theoretical (high-energy) particle physics in 1971. After brief post-doc positions at SLAC and Caltech, he went to CERN and has held an indefinite contract there since 1978. He was awarded the Maxwell Medal and the Paul Dirac Prize by the Institute of Physics in 1982 and 2005 respectively, and is an Elected Fellow of the Royal Society of London since 1985 and of the Institute of Physics since 1991. He was awarded an Honorary Doctorate from the University of Southampton, and twice won the First Award in the Gravity Research Foundation essay competition (in 1999 and 2005). He is also Honorary Doctor at Uppsala University.

Question: Where was the founder of the Quakers born? Passage:The design of the meeting house is unusual, having swayed away from the designs of traditional Quaker meeting houses. It was a result of the reunification of the two groups of Quakers that had initially separated from a schism in 1827, where two thirds of Quakers abandoned the philosophies of their founder, George Fox, and instead turned to the ideals taught by Long Island preacher, Elias Hicks. By 1926, when it was time to construct a new meeting house in Poughkeepsie, the number of local “Hicksite” Quakers was diminishing, so many had joined the Orthodox Quakers. Alfred Bussel, a New York City architect, was chosen to design a meeting house that appealed to all members. Since he had studied at Haverford College, a Quaker school, Bussell was very familiar with the Society of Friends traditions. One branch had suggested a church-like structure with steeple, organ, and stained-glass windows, while the other wanted a more traditional style meeting house, i.e. evoking simplicity, equality, community, and peace. The design therefore was a unity between the two branches, a sign of what was to come with the official reunification in the 1950s. The result is a simple, colonial revival building without stained-glass or any sort of liturgical ornamentation or symbols, as per Quaker tradition, but had a single front door (Quaker meeting houses had separate entrances for men and women) and an interior layout akin to a church; a central aisle with rows of pews on either side all facing the front of the building.

Question: How old was Lincoln Ellsworth when he first obtained phots of Eros Glacier? Passage:Eros Glacier () is a glacier on the east coast of Alexander Island, Antarctica, long and wide at its mouth, flowing southeast from the Planet Heights into George VI Sound immediately north of Fossil Bluff. It was probably first seen on November 23, 1935, by Lincoln Ellsworth, who flew directly over the glacier and obtained photos of features north and south of it. The mouth of the glacier was observed and positioned by the British Graham Land Expedition in 1936 and the Falkland Islands Dependencies Survey (FIDS) in 1948 and 1949. The glacier was mapped in detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. It was named by the UK Antarctic Place-Names Committee after the minor planet Eros in association with nearby Pluto Glacier and Uranus Glacier.
