Figure skating jumps
Jumps are referred to by how many times the skater turns in the air. One revolution (one and a half for the Axel) is a "single" jump. Two revolutions (two and a half for the Axel) is a "double" jump. Three revolutions (three and a half for the Axel) is a "triple" jump. Four revolutions (four and a half for the Axel, although this has never been done in competition) is a "quadruple" or "quad" jump. The first triple jump landed in competition was a loop jump. It was landed by Dick Button in 1952. The first quadruple jump landed in competition was a toe loop jump. It was landed by Kurt Browning in 1988. Currently, men in world-class competition usually attempt a full set of triples and sometimes one or two quadruple jumps in their free skating programs. Triple Axels are rare for ladies, and quadruple jump attempts even more so.
Bjørn G. Andersen
At the University of Bergen, Andersen played a central role in building up the study of Quaternary geology. His students and the university benefited from his international contacts and he conducted filed trips to the Antarctic, South America and New Zealand. Most of all his contribution was to reveal the foundation of Scandinavian landscapes.
Andersen's first expedition to the South Pole came in a period of small Norwegian interest in the Antarctic after the great achievements of Roald Amundsen in 1911–1912. Andersen was the second Norwegian to visit the Pole after the Amundsen expedition. An American expedition which reached the Pole a week before him honored his achievements by naming a mountain escarpment Andersen Escarpment after him.
