🔗 Musical Instruments 🔗 Electronic music

The blaster beam is a concept electric musical instrument consisting of a 12 to 18-foot (3.5 to 5.5 m) long metal beam strung with numerous tensed wires under which are mounted electric guitar pickups which can be moved to alter the sound produced. The instrument is played by plucking the strings with fingers or striking with sticks, pipes or even large objects. The instrument produces a very distinctive bass tone, the sound of which is often described as 'dark' or 'sinister'.

The blaster beam was designed by John Lazelle in the early 1970s, and was first widely used by Francisco Lupica who built several out of iron. American child-actor-turned-musician Craig Huxley created his own refined version of the beam out of aluminum which was brought to fame in the soundtrack for Star Trek: The Motion Picture (1979) in which composer Jerry Goldsmith used the instrument to create the signature V'ger sound. Earlier that year, Huxley performed his custom-built blaster beam on Robert Prince's score for the season three Wonder Woman episode "Spaced Out". The instrument was also used by composer James Horner for several of his early soundtracks, including Battle Beyond the Stars (1980) and Star Trek II: The Wrath of Khan (1982), Michael Stearns for his score to the IMAX film Chronos, and in David Shire's soundtrack to 2010 (1984), which score was co-written by Huxley. Huxley also played the instrument on the Quincy Jones song, "Ai No Corrida”.

Huxley successfully patented his design of the beam in 1984.

The instrument has since been used to create dark unnatural sounds in other movie soundtracks in the late 1970s and early 1980s, including the films The Black Hole, Forbidden World, Dreamscape, and Meteor, in the last of which it was used during shots of the giant looming meteorite as it approached Earth. It has also been used by new age artists including Kitaro, Stearns and Huxley. The blaster beam was also used for the seismic charge sound used by Jango Fett, in Star Wars: Episode II – Attack of the Clones.

Some more unexpected attention came in the early nineties when several women attending a music concert in New York's Central Park claimed to have been stimulated by the sound created by a blaster beam being used in the performance. This prompted Australian radio station 2SER-FM to conduct an experiment in which they played a continuous loop of a blaster beam performance and asked their female listeners to report any stimulation they experienced. (FM's frequency response typically starts at around 50 Hz which is similar to the theoretical lowest frequencies of the blaster beam, but these frequencies might have been more prominent at the live concert.) On this occasion none of the show's listeners reported any arousal whatsoever.

In 2016, composer Bear McCreary featured the Blaster Beam in his score to 10 Cloverfield Lane, performed by Craig Huxley.

The Church Rock uranium mill spill occurred in the U.S. state of New Mexico on July 16, 1979, when United Nuclear Corporation's tailings disposal pond at its uranium mill in Church Rock breached its dam. The spill remains the largest release of radioactive material in U.S. history, having released more radioactivity than the Three Mile Island accident four months earlier.

The mill, which operated from June 1977 to May 1982, was located on privately owned land about 17 miles (27 km) northeast of Gallup, New Mexico, and was bordered to the north and southwest by Navajo Nation Tribal Trust lands. The milling of uranium ore produced an acidic slurry of ground waste rock and fluid (tailings) that was pumped to the tailings disposal area. The breach released more than 1,100 short tons (1,000 t) of solid radioactive mill waste and 94 million US gallons (360,000 m³) of acidic, radioactive tailings solution into the Puerco River through Pipeline Arroyo. An estimated 1.36 short tons (1.23 t) of uranium and 46 curies of alpha contaminants traveled 80 miles (130 km) downstream to Navajo County, Arizona, and onto the Navajo Nation. In addition to being radioactive and acidic, the spill contained toxic metals and sulfates. The spill contaminated groundwater and rendered the Puerco unusable to local residents, mostly Navajo peoples who used the river's water for drinking, irrigation, and livestock. They were not warned for days of the toxic dangers from the spill.

The governor of New Mexico, Bruce King, refused the Navajo Nation's request that the site be declared a federal disaster area, limiting aid to affected residents. The nuclear contamination event received less media coverage than that of Three Mile Island, possibly because it occurred in a very rural area not served by major media. The spill also happened in Native American country, among a community who reportedly did not have their concerns addressed by medical authorities.

In 2003, the Church Rock Chapter of the Navajo Nation began the Church Rock Uranium Monitoring Project to assess environmental impacts of abandoned uranium mines; it found significant radiation from both natural and mining sources in the area. As of 2016, the EPA National Priorities List included the Church Rock tailings storage site, where "groundwater migration is not under control".

Automobile polo or auto polo was a motorsport invented in the United States that featured rules and equipment similar to equestrian polo but using automobiles instead of horses. The sport was popular at fairs, exhibitions and sports venues across the United States and several areas in Europe from 1911 until the late 1920s; it was, however, dangerous and carried the risk of injury and death to the participants and spectators, and expensive damage to vehicles.

🔗 Astronomy 🔗 Maps

HEALPix (sometimes written as Healpix), an acronym for Hierarchical Equal Area isoLatitude Pixelisation of a 2-sphere, is an algorithm for pixelisation of the 2-sphere and the associated class of map projections. The pixelisation algorithm was devised in 1997 by Krzysztof M. Górski at the Theoretical Astrophysics Center in Copenhagen, Denmark, and first published as a preprint in 1998.

🔗 Robotics

The Canard Digérateur, or Digesting Duck, was an automaton in the form of a duck, created by Jacques de Vaucanson and unveiled on 30 May 1764 in France. The mechanical duck appeared to have the ability to eat kernels of grain, and to metabolize and defecate them. While the duck did not actually have the ability to do this—the food was collected in one inner container, and the pre-stored feces were "produced" from a second, so that no actual digestion took place—Vaucanson hoped that a truly digesting automaton could one day be designed.

Voltaire wrote in 1769 that "Without the voice of le Maure and Vaucanson's duck, you would have nothing to remind you of the glory of France."

The duck is thought to have been destroyed in a fire at a private museum in 1879.

Artificial intelligence (AI) is used on a number of Wikipedia and Wikimedia projects. This may be directly involved with creation of text content, or in support roles related to evaluating article quality, adding metadata, or generating images. As with any machine-generated content, care must be used when employing AI at scale or in applying it where the community consensus is to exercise more caution.

When exploring AI techniques and systems, the community consensus is to prefer human decisions over machine-generated outcomes until the implications are better understood.

Paraloid B-72 or B-72 is a thermoplastic resin that was created by Rohm and Haas for use as a surface coating and as a vehicle for flexographic ink. Subsequently, it has found popular use as an adhesive by conservator-restorers, specifically in the conservation and restoration of ceramic objects, glass objects, the preparation of fossils, the hardening of piano hammers, and can also be used for labeling museum objects.

"Clanker" is a derogatory term for robots and artificial intelligence (AI) software. The term has been used in Star Wars media, first appearing in the franchise's 2005 video game Star Wars: Republic Commando. By 2025, the term had become widely used to express hatred or distaste for machines ranging from delivery robots to large language models. This trend has been attributed to anxiety around the negative societal effects of AI.

The Cahokia Mounds (also simply known as Cahokia) (11 MS 2) is the site of a Native American city (which existed c. 1050–1350 CE) directly across the Mississippi River from present-day St. Louis. The state archaeology park lies in south-western Illinois between East St. Louis and Collinsville. The park covers 2,200 acres (890 ha), or about 3.5 square miles (9 km²), and contains about 80 manmade mounds, but the ancient city was much larger. At its apex around 1100 CE, the city covered about 6 square miles (16 km²), included about 120 earthworks in a wide range of sizes, shapes, and functions, and had a population of between 15,000 and 20,000 people.

Cahokia was the largest and most influential urban settlement of the Mississippian culture, which developed advanced societies across much of what is now the Central and the Southeastern United States, beginning around 1000 CE. Today, the Cahokia Mounds are considered to be the largest and most complex archaeological site north of the great pre-Columbian cities in Mexico.

The city's original name is unknown. The mounds were later named after the Cahokia tribe, a historic Illiniwek people living in the area when the first French explorers arrived in the 17th century. As this was centuries after Cahokia was abandoned by its original inhabitants, the Cahokia tribe was not necessarily descended from the earlier Mississippian-era people. Most likely, multiple indigenous ethnic groups settled in the Cahokia Mounds area during the time of the city's apex.

Cahokia Mounds is a National Historic Landmark and a designated site for state protection. It is also one of the 26 UNESCO World Heritage Sites within the United States. The largest pre-Columbian earthen construction in the Americas north of Mexico, the site is open to the public and administered by the Illinois Historic Preservation Division and supported by the Cahokia Mounds Museum Society. In celebration of the 2018 Illinois state bicentennial, the Cahokia Mounds were selected as one of the Illinois 200 Great Places by the American Institute of Architects Illinois component (AIA Illinois). It was recognized by USA Today Travel magazine, as one of the selections for 'Illinois 25 Must See Places'.
