William Ernest Cooke - Achievements

Achievements

  • His star cataloguing system was accepted at an international astronomical conference in Paris in 1909.
  • He developed a method of plotting the transit of tropical cyclones, and issuing weather warnings for shipping and pearling industries
  • He invented a type of heliochronometer which could be used to determine local time and true north accurately. The device was known as a sunclock (picture). In 1924 the device won a gold medal at the British Empire Exhibition.
  • He recognised that by using radio signals form other parts of the world would enable the accurate measurement of longitude. He worked with his son Basil, a pioneer amateur radio operator, who received time signals from Lyons, France. This technique was used in 1921 by the WA Government Astronomer, Curlewis and the SA Government Astronomer, Dodwell, at Deakin, Western Australia to fix a position for the 129th meridian east longitude (129° east). The same group also travelled to Wyndham, Western Australia to determine the WA/NT border on the ground.
  • Cooke is said to have patented over one hundred inventions

Satellite 3894 Williamcooke and Mount Cooke in the Darling Scarp near Jarrahdale are named in his honour.

Famous quotes containing the word achievements:

    There are some achievements which are never done in the presence of those who hear of them. Catching salmon is one, and working all night is another.
    Anthony Trollope (1815–1882)

    Fathers are still considered the most important “doers” in our culture, and in most families they are that. Girls see them as the family authorities on careers, and so fathers’ encouragement and counsel is important to them. When fathers don’t take their daughters’ achievements and plans seriously, girls sometimes have trouble taking themselves seriously.
    Stella Chess (20th century)

    Our achievements speak for themselves. What we have to keep track of are our failures, discouragements, and doubts. We tend to forget the past difficulties, the many false starts, and the painful groping. We see our past achievements as the end result of a clean forward thrust, and our present difficulties as signs of decline and decay.
    Eric Hoffer (1902–1983)
