A boomerang is a simple wooden implement used for various purposes. It is primarily associated with Australian Aborigines, but other forms are found amongst peoples of North East Africa, Arizona and southern California Native Americans and in India. The oldest boomerang found so far was discovered in a cave in the Carpathian Mountains in Poland and is believed to be about 20,000 years old. Boomerangs come in many shapes and sizes depending on their geographic/tribal origins and intended function. The most recognizable type is the returning boomerang, a kind of throwing stick that, when thrown correctly, travels in a curved path and returns to its point of origin. Other types of boomerang are of the non-returning sort, and indeed, some are not thrown at all but are used in hand-to-hand combat by Aboriginal people. Boomerangs can be variously used as hunting weapons, percussive musical instruments, battle clubs, fire-starters, decoys for hunting waterfowl, and as recreational playthings. The smallest boomerang may be less than 10 cm from tip-to-tip, and the largest over 2 meters in length. Tribal boomerangs may be incised and/or painted with designs meaningful to its maker. Most boomerangs seen today are of the tourist or competition sort, and are almost invariably of the returning type.

The BOOMERanG experiment (Balloon Observations Of Millimetric Extragalactic Radiation and Geophysics) measured the cosmic microwave background radiation of a part of the sky during three sub-orbital (high altitude) balloon flights. It was the first experiment to make large, high fidelity images of the CMB temperature anisotropies. By using a telescope which flew at over 42,000 metres high, it was possible to reduce the atmospheric absorption of microwaves to a minimum. This allowed massive cost reduction compared to a satellite probe, though only a small part of the sky could be scanned.
