University Of Chicago Scavenger Hunt
The University of Chicago Scavenger Hunt (or Scav Hunt, colloquially Scav) is an annual four-day team-based scavenger hunt held at the University of Chicago from Thursday to Sunday of Mother's Day weekend in May. The list of items, usually over 300 items long, encompasses cryptograms, competitions, build challenges, a 3 course meal, and a road trip. "Scav Hunt" is well known for its quirky, strange, and impossible items. Scav held the Guinness World Record for largest scavenger hunt from 2011 to 2014. Format The Scavenger Hunt is held annually over four days in May, such that the final day's judgement of items is on Mother's Day. List release "The Hunt" begins ceremoniously at midnight of the Wednesday preceding Mother's Day weekend, with an event known as "List Release." The ceremony surrounding the unveiling of the list usually begins a few hours before midnight, as teams slowly assemble on the ground floor of Ida Noyes Hall. These teams (ranging in size from 1 to over 250 ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GPS Satellite
GPS satellite blocks are the various production generations of the Global Positioning System (GPS) used for satellite navigation. The first satellite in the system, Navstar 1, was launched on 22 February 1978. The GPS satellite constellation is operated by the 2nd Space Operations Squadron (2SOPS) of Space Delta 8, United States Space Force. The GPS satellites circle the Earth at an altitude of about 20,000 km (12,427 miles) and complete two full orbits every day. Satellites by block Block I satellites Rockwell International was awarded a contract in 1974 to build the first eight Block I satellites. In 1978, the contract was extended to build an additional three Block I satellites. Beginning with Navstar 1 in 1978, ten "Block I" GPS satellites were successfully launched. One satellite, "Navstar 7", was lost due to an unsuccessful launch on 18 December 1981. The Block I satellites were launched from Vandenberg Air Force Base using Atlas rockets that were con ...

Thorium
Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is silvery and tarnishes black when it is exposed to air, forming thorium dioxide; it is moderately soft and malleable and has a high melting point. Thorium is an electropositive actinide whose chemistry is dominated by the +4 oxidation state; it is quite reactive and can ignite in air when finely divided. All known thorium isotopes are unstable. The most stable isotope, 232Th, has a half-life of 14.05 billion years, or about the age of the universe; it decays very slowly via alpha decay, starting a decay chain named the thorium series that ends at stable 208 Pb. On Earth, thorium and uranium are the only significantly radioactive elements that still occur naturally in large quantities as primordial elements. Thorium is estimated to be over three times as abundant as uranium in the Earth's crust, and is chiefly refined from monazite sands as a by-product of extracti ...

Breeder Reactor
A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use, by irradiation of a fertile material, such as uranium-238 or thorium-232, that is loaded into the reactor along with fissile fuel. Breeders were at first found attractive because they made more complete use of uranium fuel than light water reactors, but interest declined after the 1960s as more uranium reserves were found,Helmreich, J.E. ''Gathering Rare Ores: The Diplomacy of Uranium Acquisition, 1943–1954'', Princeton UP, 1986: ch. 10 and new methods of uranium enrichment reduced fuel costs. Fuel efficiency and types of nuclear waste Breeder reactors could, in principle, extract almost all of the energy contained in uranium or thorium, decreasing fuel requirements by a factor of 100 compared to widely used once-through light water reactors, which extract less tha ...

Stradivarius
A Stradivarius is one of the violins, violas, cellos and other string instruments built by members of the Italian family Stradivari, particularly Antonio Stradivari (Latin: Antonius Stradivarius), during the 17th and 18th centuries. They are considered some of the finest instruments ever made, and are extremely valuable collector's items. According to their reputation, the quality of their sound has defied attempts to explain or equal it, though this belief is disputed. The many blind experiments from 1817 to as recently as 2014 have found no difference in sound between Stradivari's violins and high-quality violins in comparable style of other makers and periods, nor has acoustic analysis. The fame of Stradivarius instruments is widespread, appearing in numerous works of fiction. Construction Stradivari made his instruments using an inner form, unlike the French copyists, such as Jean-Baptiste Vuillaume, Vuillaume, who employed an outer form. It is clear from the number of f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeusaphone
The singing Tesla coil, sometimes called a zeusaphone, thoramin or musical lightning, is a form of plasma speaker. It is a variety of a solid state Tesla coil that has been modified to produce musical tones by modulating its spark output. The resulting pitch is a low fidelity square wave like sound reminiscent of an analog synthesizer. The high-frequency signal acts in effect as a carrier wave; its frequency is significantly above human-audible sound frequencies, so that digital modulation can reproduce a recognizable pitch. The musical tone results directly from the passage of the spark through the air. Because solid-state coil drivers are limited to "on-off" modulation, the sound produced consists of square-like waveforms rather than sinusoidal (though simple chords are possible). The term "singing Tesla coil" was coined by David Nunez, the coordinator of the Austin, Texas chapter of Dorkbot, while describing a musical Tesla coil presentation by Joe DiPrima and Oliver Greaves du ...

Chicago Sun-Times
The ''Chicago Sun-Times'' is a daily newspaper published in Chicago, Illinois, United States. Since 2022, it is the flagship paper of Chicago Public Media, and has the second largest circulation among Chicago newspapers, after the ''Chicago Tribune''. The modern paper grew out of the 1948 merger of the ''Chicago Sun'' and the ''Chicago Daily Times''. Journalists at the paper have received eight Pulitzer prizes, mostly in the 1970s; one recipient was film critic Roger Ebert (1975), who worked at the paper from 1967 until his death in 2013. Long owned by the Marshall Field family, since the 1980s ownership of the paper has changed hands numerous times, including twice in the late 2010s. History The ''Chicago Sun-Times'' claims to be the oldest continuously published daily newspaper in the city. That claim is based on the 1844 founding of the ''Chicago Daily Journal'', which was also the first newspaper to publish the rumor, now believed false, that a cow owned by Catherine O'L ...

David Hahn
David Charles Hahn (October 30, 1976 – September 27, 2016), sometimes called the "Radioactive Boy Scout" or the "Nuclear Boy Scout", was an American nuclear radiation enthusiast who built a homemade neutron source at the age of seventeen. A scout in the Boy Scouts of America, Hahn conducted his experiments in secret in a backyard shed at his mother's house in Commerce Township, Michigan. Hahn's goal was to build and demonstrate a homemade breeder reactor. While he never managed to build a reactor, in August 1994 Hahn's progress attracted the attention of local police when they found material in his vehicle that troubled them during a stop for a separate matter. When Hahn warned them that the material was radioactive, the police contacted federal authorities. His mother's property was cleaned up by the Environmental Protection Agency (EPA) ten months later as a Superfund cleanup site. Hahn attained Eagle Scout rank shortly after his lab was dismantled.
