Telstar

Telstar is the name of various communications satellites, including the first ever such satellite able to relay television signals. The first two Telstar satellites were "Telstar 1", launched July 10, 1962 and operational until February 21, 1963, and "Telstar 2", launched May 7, 1963 and operational until May 16, 1965. They were experimental, and nearly identical. Telstar 1 relayed the first television pictures, telephone calls and fax images through space and provided the first live transatlantic television feed.

Belonging to AT&T, the original Telstar was part of a multi-national agreement between AT&T, Bell Telephone Laboratories, NASA, the British General Post Office, and the French National PTT (Post, Telegraph & Telecom Office) to develop experimental satellite communications over the Atlantic Ocean. Bell Labs held a contract with NASA, reimbursing the agency three million dollars for each of the two launches, independent of success.

Launched by NASA aboard a Delta rocket from Cape Canaveral on July 10, 1962, Telstar 1 was the first privately sponsored space launch. A medium-altitude satellite, Telstar was placed in an elliptical orbit completed once every 2 hours and 37 minutes, inclined at an angle of approximately 45 degrees to the equator, with perigee about 1000 km from Earth and apogee about 6000 km from Earth (This is in contrast to most of today's communications satellites, which are placed in circular geostationary orbits.

Telstar 1 relayed its first, and non-public, television pictures – of a flag outside Andover Earth Station in Maine, USA – to France on July 11, 1962. Almost two weeks later, on July 23, at 3:00 p.m. EDT, it relayed the first publicly available live transatlantic television signal. The broadcast was made possible in Europe by Eurovision and in North America by NBC, CBS, ABC, and the CBC. The first public broadcast featured CBS's Walter Cronkite and NBC's Chet Huntley in New York, and the BBC's Richard Dimbleby in Brussels. The first pictures were the Statue of Liberty in New York and the Eiffel Tower in Paris. The first broadcast was to have been remarks by President John F. Kennedy, but the signal was acquired before the President was ready, so the lead-in time was filled with a short segment of a televised major league baseball game between the Philadelphia Phillies and the Chicago Cubs at Wrigley Field. The batter Tony Taylor was seen hitting the ball to the right fielder George Altman. From there, the video switched first to Washington, DC; then to Cape Canaveral, Florida; then to Quebec, Canada and finally to Stratford, Ontario. The Washington segment included a press conference with President Kennedy, talking about the price of the American dollar, which was causing concern in Europe.

During that evening, Telstar 1 also relayed the first telephone call to be transmitted through space, and it successfully transmitted faxes, data, and both live and taped television, including the first live transmission of television across an ocean. In August 1963, Telstar 1 became the first satellite used to synchronize time between two continents, bringing the United Kingdom and the United States to within 1 microsecond of each other (previoius efforts were only accurate to 2000 microseconds).

Telstar 1, which had ushered in a new age of the benevolent use of technology, became a victim of technology during the Cold War. The day before Telstar 1 was launched, the United States had tested a high-altitude nuclear bomb (called Starfish Prime) which energized the Earth's Van Allen Belt where Telstar 1 went into orbit. This vast increase in radiation, combined with subsequent high-altitude blasts, including a Soviet test in October, overwhelmed Telstar's fragile transistors; it went out of service in early December 1962, but was restarted by a workaround in early January 1963. The additional radiation associated with its return to full sunlight once again caused a transistor failure, this time irreparably, and Telstar 1 went out of service on February 21, 1963.

According to the US Space Objects Registry, Telstar 1 and 2 were still in orbit as of June 2009.

Chrysler Slant-6

The Slant-6 is one of Chrysler's two best known automobile engines, along with the Hemi V8. The engine is an inline-6 piston engine specifically designed such that the cylinders are inclined at a 30-degree angle from vertical. The 30° inclination of the Slant-6 gave a lower height overall engine package, which enabled vehicle stylists to lower hoodlines, and also made room for the water pump to be mounted with a significant lateral offset, significantly shortening the engine's overall length. In addition, the slanted cylinder block provided ample space under the hood for intake and exhaust manifolds with runners of longer and more nearly equal length compared to the "rake" or "log" style manifolds found on other inline engines. These manifolds give a more even cylinder-to-cylinder fuel distribution and are less restrictive for better airflow through the engine.

The engine was introduced in two sizes in 1960: The 170 cubic-inch (2.8 L) "LG" (Low-G, referring to the relatively short engine block casting and crankshaft stroke) in the Valiant, and the 225 CID (3.7 L) "RG" (Raised-G, referring to the relatively tall engine block casting and crankshaft stroke) in full-size Plymouth and Dodge Dart models. In 1960, the engine was referred to by Plymouth division as the "30-D Economy Six" engine, the "30-D" referring to the 30° cylinder block angle.

The G-engine gained an enviable reputation for reliability and nearly unstoppable durability. The basic engine design incorporates much heavy-duty engineering, in part because the engine was designed from the start to be made of either iron or aluminum: The block is of a deep-skirt design, with the crankshaft axis well above the oil pan rails for structural rigidity. Although only four main bearings are used, they are of the same dimensions as those in the Hemi. Very efficient cooling and lubrication systems, a favorable rod ratio, and an extremely strong forged steel crankshaft (on engines made through mid-1976) all contributed to the engine's apparent indestructibility. In addition, the G-engine also provided better performance than most of its competition in the 1960s and 1970s.

The G-engine was offered in various configurations in the North American market until 1983 in cars, and 1987 in trucks.

Boston Molasses Disaster

The Boston Molasses Disaster occurred on January 15, 1919, in the North End neighborhood of Boston, Massachusetts in the United States. A large molasses storage tank burst, and a wave of molasses rushed through the streets at an estimated 35 mph (56 km/h), killing 21 and injuring 150. The event has entered local folklore, and residents claim that on hot summer days, the area still smells of molasses.

The disaster occurred at the Purity Distilling Company facility on January 15, 1919, an unusually warm day. At the time, molasses was the standard sweetener in the United States. Molasses can also be fermented to produce rum and ethyl alcohol, the active ingredient in other alcoholic beverages and a key component in the manufacturing of munitions at the time. The stored molasses was awaiting transfer to the Purity plant situated between Willow Street and what is now named Evereteze Way in Cambridge, Massachusetts.

Near Keany Square, at 529 Commercial Street, a huge molasses tank 50 ft tall, 90 ft in diameter and containing as much as 2,300,000 US gallons collapsed. Witnesses stated that as it collapsed, there was a loud rumbling sound like a machine gun as the rivets shot out of the tank, and that the ground shook as if a train were passing by.

The collapse unleashed an immense wave of molasses between 8 and 15 ft high, moving at 35 mph. The molasses wave was of sufficient force to break the girders of the adjacent Boston Elevated Railway's Atlantic Avenue structure and lift a train off the tracks. Nearby, buildings were swept off their foundations and crushed. Several blocks were flooded to a depth of 2 to 3 feet (60 to 90 cm).

The Boston Globe reported that people "were picked up by a rush of air and hurled many feet." Others had debris hurled at them from the rush of sweet-smelling air. A truck was picked up and hurled into Boston Harbor. Approximately 150 were injured; 21 people and several horses were killed — some were crushed and drowned by the molasses. The wounded included people, horses, and dogs; coughing fits became one of the most common ailments after the initial blast.

Jeff "Skunk" Baxter

Jeff "Skunk" Baxter is an American guitarist best known for his stints in the rock bands Steely Dan and The Doobie Brothers during the 1970s. More recently, he has been working as a defense consultant and chairs a Congressional Advisory Board on missile defense.

While working at Manny's Music Shop in Manhattan in 1966, Baxter met guitarist Jimi Hendrix, who was just beginning his career as a frontman. For a short period during that year, Baxter was a member of a Hendrix-led band called Jimmy James and the Blue Flames, along with fellow Manny's employee Randy California.

Baxter graduated from The Taft School in Watertown, Connecticut and attended the School of Public Communication (now College of Communication) at Boston University, entering as a freshman in September 1967, where he studied journalism and continued his work with local Boston bands. Baxter first reached the larger rock audience in 1968 as a member of the psychedelic rock band Ultimate Spinach. Baxter joined that band for their third and final album, titled III. He then went on to play with the Holy Modal Rounders,

After the breakup of Ultimate Spinach, Baxter relocated to Los Angeles, California, finding work as a session guitarist. In 1972 he became a founding member of the band Steely Dan, along with guitarist-bassist Walter Becker, keyboardist Donald Fagen, guitarist Denny Dias, drummer Jim Hodder and vocalist David Palmer (and session player Elliott Randall on various tracks). Becker and Fagen were employed at the time as staff songwriters for ABC Records, and they formed the band as a vehicle to promote their songs.

Baxter appeared with Steely Dan on their first three albums, Can't Buy a Thrill in 1972, Countdown to Ecstasy in 1973, and Pretzel Logic in 1974. Among his contributions was the guitar solo on the 1974 hit single "Rikki Don't Lose That Number".

Baxter left the band in 1974 to join The Doobie Brothers, who at the time were touring in support of their fourth album What Were Once Vices Are Now Habits. As a session man, he had contributed pedal steel guitar to "Black Water" on Vices as well as "South City Midnight Lady" on its predecessor, The Captain and Me. Baxter's first album as a full member of the group was 1975's Stampede.

In early 1979, Baxter and co-founding drummer John Hartman left the band.

Baxter has continued working as a session guitarist for a diverse group of artists, including Willy DeVille, Bryan Adams, Hoyt Axton, Eric Clapton, Gene Clark, Sheryl Crow, Freddie Hubbard, Tim Weisberg,Joni Mitchell, Rick Nelson, Dolly Parton, Carly Simon, Ringo Starr, Gene Simmons, Rod Stewart, Barbra Streisand, and Donna Summer.

Baxter fell into his second profession almost by accident. In the mid-1980s, Baxter's interest in music recording technology led him to wonder about hardware and software that was originally developed for military use, i.e. data-compression algorithms and large-capacity storage devices. As it happened, his next-door neighbor was a retired engineer who had worked on the Sidewinder missile program. This neighbor bought Baxter a subscription to an aviation magazine, provoking his interest in additional military-oriented publications and missile defense systems in particular. He became self-taught in this area, and at one point he wrote a five-page paper that proposed converting the ship-based anti-aircraft Aegis missile into a rudimentary missile defense system. He gave the paper to California congressman Dana Rohrabacher, and his career as a defense consultant began.

Backed by several influential Capitol Hill lawmakers, Baxter received a series of classified security clearances. In 1995, Pennsylvania congressman Curt Weldon, then the chairman of the House Military Research and Development Subcommittee, nominated Baxter to chair the Civilian Advisory Board for Ballistic Missile Defense.

Baxter's work with that panel led to consulting contracts with the Pentagon's Missile Defense Agency (MDA) and National Geospatial-Intelligence Agency. He now consults to the U.S. Department of Defense and the U.S. intelligence community, as well as for defense-oriented manufacturers including Science Applications International Corporation ("SAIC"), Northrop Grumman Corp. and General Atomics Aeronautical Systems Inc. He has been quoted as saying his unconventional approach to thinking about terrorism, tied to his interest in technology, is a major reason he became sought after by the government.

"We thought turntables were for playing records until rappers began to use them as instruments, and we thought airplanes were for carrying passengers until terrorists realized they could be used as missiles," he has said. "My big thing is to look at existing technologies and try to see other ways they can be used, which happens in music all the time and happens to be what terrorists are incredibly good at."

In April 2005, he joined the NASA Exploration Systems Advisory Committee (ESAC).

Baxter was a member of an independent study group that produced the "Civil Applications Committee Blue Ribbon Study" recommending an increased domestic role for U.S. spy satellites in September 2005. This study was first reported by the Wall Street Journal on August 15, 2007.

Tasso Ham

Tasso ham is a specialty of Cajun cuisine. It is a spicy, peppery version of smoked pork made from the shoulder butt. In this case, "ham" is a misnomer, since tasso is not made from the hind leg of a pig. This cut is typically fatty, though leaner cuts are often used and have a great deal of flavor. The butt, which will weigh 7 to 8 pounds, is sliced across the grain into pieces about 3 in / 7.5 cm thick. These are dredged in a salt cure, which usually includes nitrates and sugar. The meat is left to cure briefly, only three or four hours, then rinsed, rubbed with a spice mixture containing Cayenne pepper and garlic, and hot-smoked until cooked through.

Tasso is not typically eaten on its own. It is used in dishes ranging from pasta to crab cakes, soup to gravy. Appropriate to its roots, tasso is most often found in recipes of southern or Cajun/Creole origin, such as jambalaya.

Polybius

Polybius is a supposed arcade game featured in an Internet urban legend. According to the story, the Tempest-style game was released to the public in 1981, and caused its players to go insane, causing them to suffer from intense stress, horrific nightmares, and even suicidal tendencies.

According to the story, an unheard-of new arcade game appeared in several suburbs of Portland, Oregon in 1981, something of a rarity at the time. The game, Polybius, proved to be incredibly popular, to the point of addiction, and lines formed around the machines, quickly followed by clusters of visits from men in black. Rather than the usual marketing data collected by company visitors to arcade machines, they collected some unknown data, allegedly testing responses to the psychoactive machines. The players themselves suffered from a series of unpleasant side-effects, including amnesia, insomnia, nightmares, night terrors, and even suicide in some versions of the legend. Some players stopped playing video games, while it is reported that one became an anti-gaming activist. The supposed creator of Polybius is Ed Rotberg, and the company named in the urban legend is Sinneslöschen (German for "sense-deletion"), often named as either a secret government organization or a codename for Atari. The gameplay is said to be similar to Tempest (a shoot 'em up game utilizing vector graphics), while the game is said to contain subliminal messages which would influence the action of anyone playing it.

The origin of the legend is unknown. Some internet commentators think it originated as a usenet hoax. Other bloggers believe the story is a true urban legend – one that grew out of exaggerated and distorted tales of an early release version of Tempest that caused problems with photosensitive epilepsy; the game was reported to have caused motion sickness and vertigo, and was therefore pulled.

Several people have claimed to have a ROM of the game, but none of them have made it available for public scrutiny, a "lack of hard evidence" situation typical of hoaxes and conspiracy theories. Conflicting information is even circulated regarding the style or genre of the game. Some sources claim it is a maze-style game, while others describe it as an action space-fighter.

The Polybius legend received some mass-market attention in the September 2003 issue of GamePro magazine, as part of a feature story on video game urban legends called "Secrets and Lies". The magazine determined the legend to be neither true nor false, but "inconclusive". Additionally, Snopes.com claims to have debunked the myth as a modern-day version of 1980's rumors of "Men in Black" visiting arcades and taking down the names of high scorers at arcade games.

At Folsom Prison

At Folsom Prison is a live album by Johnny Cash, released on Columbia Records in May 1968. Since his 1955 song "Folsom Prison Blues", Cash had been interested in performing at a prison. His idea was put on hold until 1967, when personnel changes at Columbia Records put Bob Johnston in charge of producing Cash's material. Cash had recently controlled his drug abuse problems, and was looking to turn his career around after several years of limited commercial success. Backed with June Carter, Carl Perkins, and Cash's band, the Tennessee Three, Cash performed two shows at Folsom State Prison in Folsom, California on January 13, 1968. The resulting album consisted of 15 tracks from the first show and one track from the second.

Despite little initial investment by Columbia, the album was a hit in the United States, reaching number one on the country charts and the top 15 of the national album chart. The lead single from the album, a live version of "Folsom Prison Blues", was a top 40 hit, Cash's first since 1964's "Understand Your Man". At Folsom Prison received good reviews upon its release and has since been considered one of the greatest albums of all time. The ensuing popularity revitalized Cash's career, and led to a release of a second prison album, At San Quentin. The album was re-released with additional tracks in 1999 and as a three-disc set in 2008.

Zapruder Film

The Zapruder film is a silent Standard 8 mm color home movie of the presidential motorcade of John F. Kennedy through Dealey Plaza in Dallas, Texas, on November 22, 1963, filmed by a private citizen named Abraham Zapruder. The film is the most complete visual recording of the assassination of President John F. Kennedy.

Zapruder filmed the Presidential motorcade while being steadied by his receptionist, Marilyn Sitzman, standing on top of the most western of the two concrete pedestals that extend from the John Neely Bryan north pergola concrete structure overlooking Elm Street in Dealey Plaza, Dallas, Texas at 12:30 pm Central Standard Time, November 22, 1963. The film depicts the presidential limousine from the time it completed its turn onto Elm Street until it passed out of view under a railway overpass. Of greatest notoriety is the film's depiction of a fatal shot to President Kennedy's head when his limousine was almost exactly in front of and slightly below Zapruder's position.

The film was examined by the Warren Commission and all subsequent investigations into the assassination. The Zapruder frames used by the Warren Commission were published in black and white as Commission Exhibit 885 in volume XVIII of the Hearings and Exhibits. Frames of the film have also been published in several magazines, and the film was featured in several movies. Copies of the complete film are available on the Internet.

In 1994, the Zapruder film footage was deemed "culturally significant" by the United States Library of Congress and was selected for permanent preservation in the National Film Registry.

Vasa

Vasa was a Swedish warship that was built from 1626 to 1628. The ship foundered and sank after sailing less than a nautical mile (ca 2 km) into her maiden voyage on 10 August 1628. Vasa fell into obscurity after most of her valuable bronze cannons were salvaged in the 17th century. She was located again in the late 1950s, in a busy shipping lane just outside the Stockholm harbor. She was salvaged with a largely intact hull on 24 April 1961. She was housed in a temporary museum called Wasavarvet ("The Wasa Shipyard") until 1987, and was then moved to the Vasa Museum in Stockholm. The ship is one of Sweden's most popular tourist attractions and, as of 2007, has attracted more than 25 million visitors.

Vasa was built top-heavy and had insufficient ballast. Despite an obvious lack of stability in port, she was allowed to set sail and foundered a few minutes later when she first encountered a wind stronger than a breeze. The impulsive move to set sail resulted from a combination of factors. Swedish king Gustavus Adolphus, who was abroad on the date of her maiden voyage, was impatient to see Vasa join the Baltic fleet in the Thirty Years' War. At the same time, the king's subordinates lacked the political courage to discuss the ship's structural problems frankly or to have the maiden voyage postponed. An inquiry was organized by the privy council to find someone responsible for the disaster, but no sentences were handed out.

During the 1961 recovery, thousands of artifacts and the remains of at least 15 people were found in and around the hull of the Vasa by marine archaeologists. Among the many items found were clothing, weapons, cannons, tools, coins, cutlery, food, drink and six of the ten sails. The artifacts and the ship itself have provided historians with invaluable insight into details of naval warfare, shipbuilding techniques and everyday life in early 17th-century Sweden. No expense was spared in decorating and equipping the Vasa, one of the largest and most heavily armed warships of her time, adorned with hundreds of sculptures, all of them painted in vivid colors. She was intended to express the expansionist aspirations of Sweden and the glory of king Gustavus Adolphus.
