boomerang(bo͞o`mərăng'), special form of throwing stick, used mainly by the aborigines of Australia. Other forms of throwing sticks were used by the peoples of ancient Egypt, Ethiopia, and India and by the indigenous peoples of the SW United States. The boomerang is sickle-shaped with arms slightly curved in opposite directions as in a propeller. The trajectory of a boomerang is usually an arc, but in some cases it is a full circle. The boomerang of the Australian aborigines (from whom the name is derived) is made in two types. The smaller boomerang, 12 to 30 in. (30 to 75 cm) long, is used only for sport and is thrown so that it returns to the thrower. The larger war boomerang is 24 to 36 in. (60 to 90 cm) long and does not return; it is used for hunting and warfare.
Boomerang(religion, spiritualism, and occult)
A boomerang is a configuration resembling a yod but involving a fourth planet directly opposed to the “action planet” at the tip of the yod. In a yod, two planets form a sextile (60°) aspect and both in turn form a quincunx (150°) aspect with a third planet. If lines were drawn to the center of the horoscope from all three planets, the resulting pattern would look like a capital Y. The planet at the bottom tip of the Y is said to be the action planet because its house placement is where the action takes place when the configuration is activated by a transit or a progression. The interpretation often given to a yod in a natal chart is that it indicates a life that proceeds along in a certain pattern for a period of time until the established pattern is abruptly interrupted and the native is forced to proceed in a new direction, though the new direction is one for which the person had actually been preparing for some time. A completely unanticipated promotion in one’s chosen profession, for example, might be brought about by an activated yod configuration.
When a fourth planet is involved in a yod so that it forms an opposition (180°) aspect to the action planet and semisextile (30°) aspects to the remaining two planets, the resulting formation is called a boomerang, a designation coined by Joan McEvers. In a boomerang, the situation anticipated at the point of the action planet “boomerangs” when the configuration is activated. One example McEvers uses in her explanation of the boomerang is Ralph Waldo Emerson, who had such a configuration in his natal chart and who, when fortune placed the 26-year-old minister in the pulpit of Boston’s Old North Church, found himself in a situation with which his non-conformist temperament had difficulty coping. He was eventually forced to leave the ministry. Thus, Emerson’s opportunity “boomeranged.”
a type of wooden throwing stick for combat and hunting, widely used among many Australian tribes. Sticks resembling the boomerang have also been found in ancient Egypt, southern India, Southeast Asia, and Mexico. The boomerangs known to the Australians were of the returning type and were capable of describing complex paths, closed figure eights, and so on, in flight. A returning boomerang is a curved plate that forms two vanes of unequal length; the lower surface is flat, and the upper surface is convex (its cross-section is similar to that of an airplane wing). The flight dynamics of a boomerang that is simultaneously in forward and rotational motion is very complex: the comparatively rapid rotation of the boomerang in the air creates an aerodynamic moment that affects the boomerang like a rotating gyroscope and continually deflects it from the direction of flight. The line of flight also depends on the direction of the wind and the skill of the thrower.
