A right-handed boomerang makes a counter-clockwise, circular flight to the left while a left-handed boomerang flies clockwise to the right.
“The game of life is like the game of boomerangs, deeds and words return to us sooner or later with astounding accuracy” ~Florence Skinner. The origin of the term is uncertain. The most recognisable type of the boomerang is the L-shaped returning boomerang; while non-returning boomerangs, throwing sticks (or kylies) were used as weapons, returning boomerangs have been used primarily for leisure or recreation.
It is well known as a weapon used by some Aboriginal Australian peoples for hunting.. Boomerangs have been historically used for hunting, as well as sport and entertainment.
Today's long-distance boomerangs have almost all an S or ?
For the same reason, the quality of manufactured long-distance boomerangs is often non-deterministic. Beginning in the later part of the twentieth century, there has been a bloom in the independent creation of unusually designed art boomerangs. From theoretical point of view, distance boomerangs are interesting also for the following reason: for achieving a different behaviour during different flight phases, the ratio of the rotation frequency to the forward velocity has a U-shaped function, i.e., its derivative crosses 0. Most sport boomerangs typically weigh less than 100 grams (3.5 oz), with MTA boomerangs (boomerangs used for the maximum-time-aloft event) often under 25 grams (0.9 oz).
This is to minimise drag and lower the lift.
There are different types of throwing contests: accuracy of return; Aussie round; trick catch; maximum time aloft; fast catch; and endurance (see below). At the very time when Aboriginal people and culture were subject to policies that removed them from their traditional lands and sought to assimilate them (physiologically and culturally) into mainstream white Australian culture, causing the Stolen Generations,[41] Aboriginalia found an ironically "nostalgic", entry point into Australian popular culture at important social locations: holiday resorts and in Australian domestic interiors. ... the white spectators were justly astonished at the dexterity and incredible force with which a bent, edged waddy resembling slightly a Turkish scimytar, was thrown by Bungary, a native distinguished by his remarkable courtesy. Practically, it means that the boomerang being at the furthest point has a very low forward velocity. Valaris are usually made of iron which is melted and poured into moulds, although some may have wooden limbs tipped with iron. A properly thrown boomerang will travel out parallel to the ground, sometimes climbing gently, perform a graceful, anti-clockwise, circular or tear-drop shaped arc, flatten out and return in a hovering motion, coming in from the left or spiralling in from behind. As of 2017[update], teams from Germany and the United States dominated international competition. Boomerangs were, historically, used as hunting weapons, percussive musical instruments, battle clubs, fire-starters, decoys for hunting waterfowl, and as recreational play toys. The weapon, thrown at 20 or 30 yards [18 or 27 m] distance, twirled round in the air with astonishing velocity, and alighting on the right arm of one of his opponents, actually rebounded to a distance not less than 70 or 80 yards [64 or 73 m], leaving a horrible contusion behind, and exciting universal admiration. The development of tourist art and souvenirs—the arc of the boomerang: from hunting, fighting and ceremony to tourist souvenir.
This feature, along with carefully executed bends and twists in the wings help to set up an "auto-rotation" effect to maximise the boomerang's hover time in descending from the highest point in its flight. Scates, B. The grip used depends on size and shape; smaller boomerangs are held between finger and thumb at one end, while larger, heavier or wider boomerangs with one or two fingers wrapped over the top edge in order to induce a spin. It's simple, really - what you send out you get back.
Non-discipline record: Smallest Returning Boomerang: Sadir Kattan of Australia in 1997 with 48 millimetres (1.9 in) long and 46 millimetres (1.8 in) wide.
