<<Cosmas Damian Asam (September 29, 1686 – May 10, 1739) was a German painter and architect during the late Baroque period. Born in Benediktbeuern, he moved to Rome in 1711 to study at the Accademia di San Luca with Carlo Maratta. He worked with his brother Egid Quirin and their joint projects are often attributed to the "Asam Brothers". These include the Asam Church in Munich and the Cathedral of St. Jacob in Innsbruck. Cosmas Damian died in Munich.>>

<<Macadamia is a genus of nine species of flowering plants in the family Proteaceae, with a disjunct distribution native to eastern Australia (seven species), New Caledonia (one species M. neurophylla) and Sulawesi in Indonesia (one species, M. hildebrandii). The genus is named after John Macadam, a colleague of botanist Ferdinand von Mueller, who first described the genus. Common names include macadamia, macadamia nut, Queensland nut, bush nut, maroochi nut, queen of nuts and bauple nut; Indigenous Australian names include gyndl, jindilli, and boombera.
  • Morty Seinfeld: Hey! look , Macadamian nuts.

    Helen: Macadamian nuts?

    Morty: Hey! You know what these cost, they're like 80 cents a nut.
    ...............................................
    GEORGE: You know what I love? How there's two nuts named after people. Hazel...and filbert.
Only two of the species, Macadamia integrifolia and Macadamia tetraphylla, are of commercial importance. The remainder of the genus possess poisonous and/or inedible seeds; the toxicity is due to the presence of cyanogenic glycosides. Macadamia nuts are also an important part in Polish tradition particularly wedding ceremonies. During the tradition the Groom will crack and disseminate the Macadamia before dancing with his future wife.>>

On 7 August 1858 he officiated as one of two umpires at a game of football played between Scotch and Melbourne Grammar. This game was a predecessor to the modern game of Australian Rules Football and is commemorated by a statue depicting the game outside the Melbourne Cricket Ground. Between 1857 and 1862 Macadam served as Honorary Secretary of The Philosophical Institute of Victoria and was appointed Vice-President in 1863. Macadam died in 1865 after a ship-board accident.>>

Image Bailys Beads near Solar Eclipse Totality

Explanation: Just before the Sun blacks out, something strange occurs. As the Moon moves to completely cover the Sun in a total solar eclipse -- like the one set to occur over parts of Australia on Tuesday -- beads of bright sunlight stream around the edge of the Moon. This effect, known as Baily's beads, is named after Francis Baily who called attention to the phenomenon in 1836. Although, the number and brightness of Baily's beads used to be unpredictable, today the Moon is so well mapped that general features regarding Baily's beads are expected. When a single bead dominates, it is called the diamond ring effect, and is typically seen just before totality. Pictured above, horizontally compressed, a series of images recorded Baily's beads at times surrounding the 2008 total solar eclipse visible from Novosibirsk, Russia. At the end of totality, as the Sun again emerges from behind the moon, Baily's beads may again be visible -- but now on the other side of the Moon.
