Valston Hancock.
Valston Hancock (31 May 1907 – 29 September 1998) was a senior commander in the Royal Australian Air Force (RAAF). A graduate of the Royal Military College, Duntroon, Hancock transferred to the RAAF in 1929 and qualified as a pilot. After fifteen years of occupying staff and training posts, he saw combat in the Aitape–Wewak campaign of the Pacific War during 1945. Flying Bristol Beaufort light bombers, he led No. 100 Squadron, and later No. 71 Wing, earning the Distinguished Flying Cross. After the war, Hancock became the inaugural commandant of RAAF College, followed by a succession of senior positions, before being promoted to air marshal and serving as Chief of the Air Staff from 1961 to 1965. He was knighted in 1962. In his role as the Air Force's senior officer, Hancock continued the policy of developing a chain of forward airfields in Northern Australia. He also evaluated potential replacements for the RAAF's English Electric Canberra bomber.

Rigel

Rigel.
Rigel is a blue supergiant star in the constellation of Orion, approximately 860 light-years (260 pc) from Earth. It is the brightest and most massive component of a star system of at least four stars that appear as a single blue-white point of light to the naked eye. A star of spectral type B8Ia, Rigel is calculated to be anywhere from 61,500 to 363,000 times as luminous as the Sun, and 18 to 24 times as massive. Its radius is over 70 times that of the Sun, and its surface temperature is 12,100 K. Rigel varies slightly in brightness, its apparent magnitude ranging from 0.05 to 0.18. It is classified as an Alpha Cygni variable. It is generally the seventh-brightest star in the night sky and is usually the brightest star in Orion, though it is occasionally outshone by Betelgeuse. With an estimated age of 7 to 9 million years, Rigel has exhausted its core hydrogen fuel, expanded and cooled to become a supergiant. It will end its life as a type II supernova.

Margaret Macpherson Grant

Margaret Macpherson Grant.
Margaret Macpherson Grant (1834–1877) was a Scottish heiress and philanthropist. Born in Aberlour parish to a local surgeon, she was educated in Hampshire and inherited a large fortune from her uncle, Alexander Grant, a planter and merchant who had become rich in Jamaica. Macpherson Grant took up residence in Aberlour House, which had been built for her uncle by William Robertson. She lived unconventionally for a woman of her time, entering into what was described as a form of marriage with a female companion, Charlotte Temple, whom she met in London in 1864. Macpherson Grant donated generously to charitable enterprises, establishing an orphanage (now the Aberlour Child Care Trust) and founding St Margaret's Episcopal Church in Aberlour. She made several wills over the course of her life that would have left her estate to Temple, but after Temple left her to marry a man, Macpherson Grant revoked her will, and the bulk of her fortune went to cousins, who were probably unknown to her.

Banksia blechnifolia

Banksia blechnifolia.
Banksia blechnifolia is a species of flowering plant that was first described by Victorian state botanist Ferdinand von Mueller in 1864. Its leaves are reminiscent of the fern genus Blechnum. B. blechnifolia is one of several closely related species that grow as prostrate shrubs, with horizontal stems and thick, leathery upright leaves. The red-brown flower spikes are up to 20 centimetres (8 in) high and appear from September to November. As the spikes age, they turn grey and develop as many as 25 woody seed pods. Insects such as bees, wasps, ants and flies pollinate the flowers. Found in sandy soils in the south coastal region of Western Australia in the vicinity of Lake King, B. blechnifolia is non-lignotuberous, regenerating by seed after bushfire. The plant adapts readily to cultivation, growing in well-drained sandy soils in sunny locations. It is suitable for rockeries and as a groundcover.
