Query: What is the origin of the word "eureka"?
Eureka (Greek: Εύρηκα) is an interjection used to celebrate a discovery or invention. It is a transliteration of an exclamation attributed to Ancient Greek mathematician and inventor Archimedes.
The city of Eureka, California, founded in 1850, uses the California State Seal as its official seal. Eureka is a considerable distance from Sutter's Mill, but was the jumping off point of a smaller gold rush in nearby Trinity County, California in 1850. It is the largest of at least eleven remaining US cities and towns named for the exclamation, "eureka!". As a result of the extensive use of the exclamation dating from 1849, there were nearly 40 locales so named by the 1880s in a nation that had none in the 1840s.[9] Many places, works of culture, and other objects have since been named "Eureka"; see Eureka (disambiguation) for a list.
Eureka is a small community centered on the intersection of what is now U.S. 24 and Illinois 117. It is also one of the towns along the Ronald Reagan Trail, a series of roads that connect towns in central Illinois that were of importance to Reagan's early life. President Reagan attended and graduated from Eureka College, whose campus is in Eureka.
The Eureka Spurs () are several rock spurs exposed along the east side of the head of Mariner Glacier, southwest of Mount McCarthy, in Victoria Land. They were so named, after the ancient Greek word eureka, by the Victoria University of Wellington Antarctic Expedition field party to Evans Neve, 1971–72, on the occasion of fossil discoveries made in the area.
The exclamation 'Eureka!' is attributed to the ancient Greek scholar Archimedes. He reportedly proclaimed "Eureka! Eureka!" after he had stepped into a bath and noticed that the water level rose, whereupon he suddenly understood that the volume of water displaced must be equal to the volume of the part of his body he had submerged. (This relation is not what is known as Archimedes' principle—that deals with the upthrust experienced by a body immersed in a fluid.[2][3]) He then realized that the volume of irregular objects could be measured with precision, a previously intractable problem. He is said to have been so eager to share his discovery that he leapt out of his bathtub and ran naked through the streets of Syracuse.
"Eureka" comes from the Ancient Greek word εὕρηκα heúrēka, meaning "I found (it)", which is the first person singular perfect indicative active of the verb εὑρίσκω heuriskō "I find".[1] It is closely related to heuristic, which refers to experience-based techniques for problem solving, learning, and discovery.
Eureka was originally laid out as "Walnut Grove" in 1855. The name was changed to "Eureka" because of a naming conflict with another Walnut Grove. Sources differ on who proposed the name Eureka. The city is named from the Greek expression Eureka, meaning "I have found it".
Another mathematician, Carl Friedrich Gauss, echoed Archimedes when in 1796 he wrote in his diary, "ΕΥΡΗΚΑ! num = Δ + Δ + Δ", referring to his discovery that any positive integer could be expressed as the sum of at most three triangular numbers.[11] This result is now known as Gauss' Eureka theorem[12] and is a special case of what later became known as the Fermat polygonal number theorem.
The Rebecca/Eureka transponding radar was a short-range radio navigation system used for the dropping of airborne forces and their supplies. It consisted of two parts, the Rebecca airborne transceiver and antenna system, and the Eureka ground-based transponder. Rebecca calculated the range to the Eureka based on the timing of the return signals, and its relative position using a highly directional antenna. The 'Rebecca' name comes from the phrase "Recognition of beacons". The 'Eureka' name comes from the Greek word meaning "I have found it!".
The expression is also the state motto of California, referring to the momentous discovery of gold near Sutter's Mill in 1848. The California State Seal has included the word eureka since its original design by Robert S. Garnett in 1850; the official text from that time describing the seal states that this word's meaning applies "either to the principle involved in the admission of the State or the success of the miner at work". In 1957 the state legislature attempted to make "In God We Trust" the state motto as part of the same post WWII anti-Communist movement that successfully added the term "under God" to the American Pledge of Allegiance in 1954, but this attempt did not succeed and "Eureka" was made the official motto in 1963.[8]
Eureka is a small eastern suburb of Ballarat, Victoria, Australia – (AU). It was originally part of Ballarat East but became its own suburb in 1946 in recognition of the area's significance to Australian history. Eureka is bordered by Specimen Creek to the north, Canadian Creek to the south, Queen and Joseph streets to the west and Kline and Stawell Street to the east. The suburb takes its name from the Eureka Lead – a lead is an ancient river bed that contains gold – of the Eureka Mining Company and is most notable as the site of the historic event of the Eureka Rebellion. This was the site where the rebel miners flew the Eureka Flag for the first time, a flag that has since become a symbol of the working class and trade union movement. The site is marked by several monuments and a museum called the Museum of Australian Democracy at Eureka (M.A.D.E), which opened in May 2013 and houses the original Eureka Flag, on loan from the Art Gallery of Ballarat.
On June 7, 1911, seven ministers and sixteen congregations organized to form the Eureka Classis. The name of the Classis came from the Greek word ‘eureka’ which means ‘I found it’ and not on the town Eureka, South Dakota, where the second meeting of the Classis would be held. The name was designed to mean that they had found a solution to their doctrinal problems with the rest of the denomination. 
The Museum focused on the Eureka Stockade as the place of origin of Australia's democracy. The Museum housed the original Eureka Flag, upon which the rebels swore an oath to the flag as a symbol of defiance against the ruling colonial government. The flag was on loan from the Art Gallery of Ballarat.
Eureka (also called "Eureka!") is an Australian musical with music by Michael Maurice Harvey, book and lyrics by Gale Edwards and John Senczuk and original book and lyrics by Maggie May Gordon.

After her transformation, Sakuya erects a barrier around temple city, blocking out everything, including trapar (which is now poisonous to her). Norb eventually brings the Gekkostate to meet Sakuya, since her help is needed to get Renton and Eureka past the Great Wall successfully. Eureka meets with Sakuya in another reality in the form of a library. There they talk about what they learned and how Sakuya and Norb first met. After sending Eureka back, she and Norb stay in the temple to disable the barrier around it and use the energy to help Eureka and Renton pass through the Great Wall. For Sakuya and Norb, they were taken to the Zone where they could be together while Renton and Eureka discovered Earth.
The city was named from the Greek word "eureka", meaning "I have found it!" The city and its history was explored on the show "Ghost Adventures" in 2018.

Eureka or Eureka Landing, is a former mining town and steamboat landing, now a ghost town, on the Arizona bank of the Colorado River in what is now La Paz County, Arizona. It was originally located in Yuma County, Arizona from 1863 through the 1870s.
Eureka was originally known as "Ruby Hollow" before it developed into a bustling mining town. Incorporated as a city in 1892, Eureka became the financial center for the Tintic Mining District, a wealthy gold and silver mining area in Utah and Juab counties. The district was organized in 1869 and by 1899 became one of the top mineral-producing areas in Utah. The Eureka Micropolitan Statistical Area housed the "Big Four" mines—Bullion Beck and Champion, Centennial Eureka, Eureka Hill, and Gemini-and later the Chief Consolidated Mining Company.
Eureka's role as the central financial point for the district ensured its survival. It housed business establishments, including the second-ever JCPenney store (then called the Golden Rule Store), financial institutions, local and county governmental buildings including Eureka City Hall (1899) and a Juab County Courthouse (1892), various churches, and the meeting places for numerous labor, social, and fraternal organizations. Mining entrepreneurs such as John Q. Packard, John Beck, Jesse Knight, and Walter Fitch Sr. were important figures in Eureka and Tintic history. In 1979, Eureka was placed in the National Register of Historic Places as part of the Tintic Mining District Multiple Resource Area, recognizing the importance of remaining buildings and sites.
According to a report by the City of Eureka, the Greater Eureka area minimally includes the unincorporated adjacent or nearby neighborhoods and Census Defined Populated Areas of Bayview, Cutten, Elk River, Freshwater, Humboldt Hill, Indianola, Myrtletown, Pine Hill, Ridgewood Heights, and Rosewood, all of which have Eureka addresses, postal zip codes and Eureka-specific telephone numbers. The Greater Eureka area makes up the largest urban settlement on the Pacific Coast between San Francisco and Portland. This area is similar to what the U.S. Census officially defines as the Eureka UC (urban cluster), which is a "densely settled core of census tracts and/or census blocks that meet minimum population density requirements, along with adjacent territory containing non-residential urban land uses as well as territory with low population density included to link outlying densely settled territory with the densely settled core" of up to 50,000 in population. The bayside communities of Manila, Samoa, and Fairhaven (all on the Samoa Peninsula), and King Salmon and Fields Landing (both located south of the city), and communities listed above, with the exception of Elk River and Freshwater, are shown to be part of the Eureka Urban Cluster. A 2011 community study performed by the St. Joseph Health System, projects increased growth of 20,000 to occur in the unincorporated communities (outskirts) located adjacent to Eureka. If that forecast is realized, Greater Eureka could achieve a population of at least 65,000, barring any increase within the city limits. Eureka is the largest city of the Eureka-Arcata-Fortuna Micropolitan Area, a construct of the U.S. Census Bureau, which is synonymous with the County of Humboldt.
Production of the movie triggered inevitable historical controversies. Various historical societies claimed ownership of the original Eureka flag. The design of the flag used in the film differs from the original Eureka flag. Peter Lalor's great-grandson complained about Chips Rafferty's casting, claiming he was nothing like Lalor.
The city is famous in Australia for the Eureka Rebellion, the only armed rebellion in Australian history. In response to this event the first male suffrage in Australia was instituted and as such Eureka is interpreted by some as the origin of democracy in Australia. The rebellion's symbol, the Eureka Flag, has become a national symbol and is held at the Museum of Australian Democracy at Eureka in Ballarat.
Eureka is one of California's historic landmarks. The California State Historical marker, #477, designating Eureka, is located in Old Town, one of the nation's best preserved original Victorian era commercial districts. The city was voted as the No. 1 best small art town in John Villani's book "The 100 Best Small Art Towns in America." Eureka hosts the region's largest monthly cultural and arts event, "Arts' Alive!" on the first Saturday of each month. More than 80 Eureka business and local galleries open their doors to the public. Often local cuisine and beverages accompany live performances by acclaimed regional bands and other types of performance art. The downtown Eureka area is also decorated with many murals.
