“Fight Against Stupidity And Bureaucracy”

.

By special request, today’s significant number is the number six. My thanks to John in Australia for the suggestion, turns out it was a very interesting choice. So let’s get started. Enjoy.

## The Number Six  6

.

.

In religion

• Chapter One of Genesis, the first book in the Old Testament, tells us that the Creation was done over a six day period, and that man was created on day number 6. Moreover, six days were appointed to man for his labor, while one day is associated in sovereignty with the Lord God, as His rest.
• The serpent also was created on the sixth day.
• The Sixth Commandment relates to the worst sin – murder.
• The sixth clause of the Lord’s prayer treats of sin.
• There are six points on a Star of David.
• There are six Orders of the Mishnah.
• Six symbolic foods are placed on the Passover Seder Plate.
• The Jewish holiday of Shavuot starts on the sixth day of the Hebrew month of Sivan.

.

• In Islam there are Six articles of belief
• Fasting six days of Shawwal, together with the month of Ramadan, is equivalent to fasting the whole year

.

• In Hindu theology, a trasarenu is the combination of 6 celestial paramanus (atoms)

.

In mathematics

• Six is the first number which is neither a square number nor a prime number.
• Six is the largest of the four all-Harshad numbers.
• There are six basic trigonometric functions.
• A cube has six faces.

• A hexagon is a regular polygon with six sides.
• A hexahedron is a polyhedron with six faces, with a cube being a special case.
• S6, with 720 elements, is the only finite symmetric group which has an outer automorphism. This automorphism allows us to construct a number of exceptional mathematical objects such as the S(5,6,12) Steiner system, the projective plane of order 4 and the Hoffman-Singleton graph.
• Six similar coins can be arranged around a central coin of the same radius so that each coin makes contact with the central one (and touches both its neighbors without a gap), but seven cannot be so arranged. This makes 6 the answer to the two-dimensional kissing number problem. The densest sphere packing of the plane is obtained by extending this pattern to the hexagonal lattice in which each circle touches just six others.

In science

• Six is the atomic number of carbon.
• A benzene molecule has a ring of six carbon atoms.
• The prefix “hexa-“ (Greek word for ‘six’) also occurs in the systematic name of many chemical compounds, such as “hexamethyl”.
• A hexamer is an oligomer made of six sub-units.
• Adenine is one of four bases that code for all life in deoxyribonucleic acid. Adenine’s molecular structure is based on a hexagonal ring bonded to a pentagonal ring.

• In the Standard Model of particle physics, there are six types of quark and six types of lepton.
• In statistical mechanics, the six-vertex model has six possible configurations of arrows at each vertex.
• The six-fold symmetry of snowflakes arises from the hexagonal crystal structure of ordinary ice.
• People with sexdactyly have six fingers on each hand.

• Six babies delivered in one birth are sextuplets.
• There are six tastes in traditional Indian Medicine called Ayurveda: sweet, sour, salty, bitter, pungent, and astringent. These tastes are used to suggest a diet based on the symptoms of the body.
• Phase 6 is one of six pandemic influenza phases.
• The cells of a beehive honeycomb are 6-sided.

• Insects have 6 legs.
• The measuring instrument called a sextant got its name because its shape forms one-sixth of a whole circle.

In space

• The New General Catalogue object NGC 6 is a spiral galaxy in the constellation Andromeda.
• Messier object M6, a magnitude 4.5 open cluster in the constellation Scorpius, also known as the Butterfly Cluster.
• The gaseous planet Saturn has hexagonal clouds on its north pole discovered by Voyager 1 in 1977 and verified again in 2006 by the Cassini spacecraft, meaning this hexagon is a persistent structure on the scale of a planet.

.

• Apollo 6
• Apollo 6, the final unmanned mission of the United States Apollo Program, was launched on April 4, 1968. It was an A type mission and the second test flight for the Saturn V launch vehicle, intended to demonstrate full lunar injection capability of the Saturn V with a nearly full simulated payload, and also the capability of the Command Module’s heat shield to withstand a lunar-speed re-entry.
• The mission was not designed to go to the moon, but merely to achieve a trans-lunar speed toward an imaginary point in space nowhere near the moon, then turn around and return in about 10 hours.
• However, fuel line failures in several Saturn V second and third stage engines prevented it from achieving lunar injection, but it was able to get close to lunar return velocity by using the Apollo spacecraft’s engine, as was done on Apollo 4, the first Saturn V test. Despite the engine failures, the flight nonetheless provided NASA with enough confidence in the Saturn V to use it for manned launches.

In politics

• Massachusetts was sixth to receive statehood on, Wednesday, February 6, 1788.
• The Sixth Amendment (Amendment VI) to the United States Constitution is the part of the United States Bill of Rights that sets forth rights related to criminal prosecutions. The Supreme Court has applied the protections of this amendment to the states through the Due Process Clause of the Fourteenth Amendment.
• The sixth President of the United States of America was John Quincy Adams (1767–1848) who served from March 4, 1825 to March 4, 1829. His V.P. Was John C. Calhoun.

.

• The sixth Prime Minister of Australia was Sir Joseph Cook, (7 December 1860 – 30 July 1947). A coal miner from Silverdale, Staffordshire, Cook emigrated to Lithgow, New South Wales during the late 1880s, and became General-Secretary of the Western Miners Association in 1887.
• He was a founding member of the Australian Labor Party, and was elected to the New South Wales Legislative Assembly as Member for Hartley in 1891.
• Later Cook switched to the Free Trade Party, and was a minister in the cabinet of Premier George Reid from 1894 to 1899. During Australia’s first federal election in 1901, Cook was elected unopposed to the federal seat of Parramatta, and served as the deputy to Reid, then Alfred Deakin, following the creation of the Commonwealth Liberal Party from Cook’s and Deakin’s parties.
• As leader of the Liberal Party, Cook became Prime Minister following the 1913 elections; but he only had a one-seat majority in the lower house and no majority at all in the upper house, so he repeatedly sought to obtain a double dissolution. The outbreak of World War I just before the September 1914 election led to a Labor victory. Following a split in the Labor party in 1916, Cook joined William Morris Hughes’ Nationalist Party of Australia, and following the Nationalist victory in the 1917 election, served as Minister for the Navy, then Treasurer under Hughes.
• In 1921 Cook resigned from the federal parliament, and was appointed Australian High Commissioner in London. During 1928 and 1929, he headed the Royal Commission into South Australia as affected by Federation. He died in Sydney in 1947.

.

• Australia has six states, Queensland (capital, Brisbane); New South Wales (capital, Sydney); Victoria (capital, Melbourne); Tasmania (capital, Hobart);        South Australia (capital, Adelaide); and Western Australia (capital, Perth). The Northern Territory (capital, Darwin), as the name implies, is classed as a ‘territory’, not a ‘state’.

.

• The ‘Six Counties’ is a term used to describe Northern Ireland which consists of the six north-eastern counties of the island of Ireland. It was created when Ireland was partitioned in 1921.  After a campaign of terrorism, murder and bombing lasting almost thirty years the London government (of first Conservative John Major and later Labour Tony Blair) along with the Clinton administration brought about a ‘peace’ agreement that saw terrorists installed as part of the Northern Ireland government in Belfast. This was done during the 1990s and pre the 9/11 terrorists attacks on New York when Americans got first hand experience of what terrorism was all about. It is questionable if a post 9/11 American administration would have been so keen to participate in appeasing terrorism.

In sport

• The National Basketball Association and National Hockey League have six divisions.
• The Original Six teams in the National Hockey League are Toronto, Chicago, Montreal, New York, Boston, and Detroit. They are the oldest remaining teams in the league, though not necessarily the first six; they comprised the entire league from 1942 to 1967.
• In American college football, there are six conferences that automatically qualify for Bowl Championship Series games.
• Six-man football is a variant of American or Canadian football, played by smaller schools with insufficient enrollment to field the traditional 11-man (American) or 12-man (Canadian) squad.
• In a football (soccer) game each side is allowed a maximum of three substitutes, making six in all.
• In ice hockey, six is the number of players per team, including the goaltender, that are on the ice at any one time, excluding penalty situations.
• In volleyball, six players from each team on each side play against each other.
• In some sports, six goals is known as a double-hat-trick, but is very hard to accomplish. A hat-trick in sport is the achievement of a positive feat three times or more during a game, or other achievements based on threes. The term was first used in 1858 in cricket to describe H H Stephenson’s feat of taking three wickets in three balls. A collection was held for Stephenson, and he was presented with a hat bought with the proceeds. The term was used in print for the first time in 1878 and was eventually adopted by many other sports including association football, water polo, and team handball, but did not become popular in North America until the mid-1940s in the National Hockey League.
• In American and Canadian football, a touchdown earns 6 points.
• In Australian Rules football, six points are received for a goal.
• In cricket there are six balls to an over, and a “six” or “sixer” is a shot in which the ball clears the boundary without bouncing, scoring six runs.
• In rugby union, the starting blindside flanker wears jersey number 6. (Some teams use “left” and “right” flankers instead of “openside” and “blindside”, with 6 being worn by the starting left flanker.)
• In most rugby league competitions (but not the European Super League, which uses static squad numbering), the jersey number 6 is worn by the starting stand-off half (Southern Hemisphere term) or five-eighth (Northern Hemisphere term).
• In football (soccer) AC Milan retired shirt number 6 belonging to their legendary center back and captain Franco Baresi in 1997.

• In Britain, Arsenal retired the number 6 shirt after their long serving center back and captain Tony Adams retired in 2002.

• In Major League Baseball: the Atlanta Braves, for manager Bobby Cox; the Boston Red Sox, for Johnny Pesky; the Detroit Tigers, for Hall of Famer Al Kaline; the Minnesota Twins, for Tony Oliva; the St. Louis Cardinals, for Hall of Famer Stan Musial; the San Diego Padres, for Steve Garvey.
• In the NBA: the Boston Celtics, for Hall of Famer Bill Russell; the Orlando Magic, for their fans (the “sixth man”); the Philadelphia 76ers, for Hall of Famer Julius Erving; the Phoenix Suns, for Walter Davis; the Sacramento Kings, also for their fans.
• In the NFL: the Kansas City Chiefs, for Warren McVea.
• In the NHL: the Detroit Red Wings, for Larry Aurie; the Pittsburgh Penguins, for Ian Ackerman; the Toronto Maple Leafs, for Hall of Famer Ace Bailey (the Leafs have a unique policy of not retiring numbers unless the player honored either died or suffered a career-ending incident while a member of the team. Bailey suffered a fractured skull during a game in 1933; while he recovered and lived for nearly 60 years after the incident, he never played again. The Leafs would issue the number to Ron Ellis in 1968 at Bailey’s personal request, and Ellis wore it until his own retirement in 1981.)
• In NASCAR, the number 6 is currently owned by Roush Fenway Racing. Since the 2007 season, the first year in which Roush Racing was merged with the Fenway Sports Group that owns the Boston Red Sox, the Cup Series version of the car has been driven by David Ragan. From 1988 to 2006, Mark Martin drove the #6 in the Cup Series for what was then Roush Racing.

In militaria

• Carrier Air Wing Six
• Carrier Air Wing Six (CVW-6) was a United States Navy aircraft carrier air wing whose operational history spans from the years prior to World War II to the end of the Cold War, including participating in the Battle of Midway, the Battle of the Eastern Solomons, and the Vietnam War.
• When the unit was named “Air Group Six” during its time on the Enterprise, it was the Navy’s only carrier-based air group to carry out three complete tours of duty during World War II.
• It was based on 15 different carriers during its operational lifetime. The lineage of Carrier Air Wing Six can be traced to the Enterprise Air Group, created on 1 July 1938, which included the following squadrons and aircraft:
• Bombing Six (VB-6) — 18 Douglas SBD-2 Dauntless dive bombers
• Fighting Six (VF-6) — 18 Grumman F4F-3 Wildcat fighter
• Scouting Six (VS-6) — 18 Douglas SBD-2 Dauntless dive bomber
• Torpedo Six (VT-6) — 18 Douglas TBD Devastator torpedo bomber

.

• Douglas DC-6
• The Douglas DC-6 is a piston-powered airliner and transport aircraft built by the Douglas Aircraft Company from 1946 to 1958. Originally intended as a military transport near the end of World War II, it was reworked after the war to compete with the Lockheed Constellation in the long-range commercial transport market.
• More than 700 were built and many still fly today in cargo, military and wildfire control roles.
• The DC-6 was known as the C-118 Liftmaster in United States Air Force service and as the R6D in United States Navy service prior to 1962, after which all U.S. Navy variants were also designated as the C-118.

.

• Shenyang F-6
• The F-6 was a Chinese copy of the MiG-19S Farmer-C cannon-armed day fighter. From the late 1960s to the final batch in 1971, a total of more than 70 F-6s were reported delivered, equipping six squadrons at 3 bases, for both interceptor and attack duties. Some of the 1971 batch were late production F-6C version, featuring a prominent braking parachute housing at the base of the rudder.
• A few FT-6 two-seat trainers also appear to have been supplied. The FT-6 wasn’t certified for production until December 1973, so these examples must have been delivered after this date. It is also reported that 4 F-6 aircraft are fitted with ventral cameras for the reconnaissance role – whether these are export versions of the JZ-6 or local conversions is not known.

.

• Beechcraft T-6 Texan II
• Developed from the Pilatus PC-9, the Beechcraft T-6 Texan II is a single-engined turboprop aircraft built by the Raytheon Aircraft Company (now Hawker Beechcraft). The T-6 is used by the United States Air Force for basic pilot training and by the United States Navy for Primary and Intermediate Joint Naval Flight Officer (NFO) and Air Force Combat Systems Officer (CSO) training. It has replaced the Air Force’s T-37B Tweet and is replacing the Navy’s T-34C Turbo Mentor.
• The T-6A is also used as a basic trainer by the Royal Canadian Air Force (CT-156 Harvard II), the German Air Force, the Greek Air Force, the Israeli Air Force (Efroni), and the Iraqi Air Force.

.

• AT-6
• As well as being an initial trainer, the multirole Hawker Beechcraft AT-6 is capable of performing missions including: net-centric ISR with the ability for precise geo-registration, streaming video and datalinks, light attack including combat search and rescue (CSAR), close air support, forward air control and convoy escort, homeland defense (border security), port security, counter-narcotics operations and civil missions such as disaster area reconnaissance, search and rescue and firefighting. There are tandem HOTAS (hands on throttle and stick) controls fore and aft for pilot and instructor.
• Hawker Beechcraft showcased the AT-6 at the Royal International Air Tattoo and Farnborough International Airshow in the UK in 2010.

.

• Fiat L6/40
• The Fiat L6/40 was a light tank used by the Italian army from 1940 and on through World War II. It was designed by Fiat-Ansaldo as an export product, and was adopted by the Italian Army when officials learned of the design and expressed interest. It was the main tank employed by the Italian forces fighting on the Eastern Front alongside the L6/40-based Semovente 47/32 self-propelled gun. L6/40s were also used in the North African campaign.
• The official Italian designation was Carro Armato (“armored tank”) L 6/40. This designation is understood as follows: “L” for Leggero (Italian: “light”), followed by the weight in tons (6) and the year of adoption (1940).

.

• Ordnance QF 6 pounder
• The Ordnance Quick-Firing 6-pounder 7 cwt, or just 6 pounder, was a British 57 mm gun, their primary anti-tank gun during the middle of World War II, as well as the main armament for a number of armoured fighting vehicles.
• It was first used in North Africa in April 1942, and quickly replaced the 2 pounder in the anti-tank role, allowing the 25 pounder to revert to its intended artillery role.
• The United States Army also adopted the 6 pounder as their primary anti-tank gun under the designation 57 mm Gun M1.

.

• The Six Gun
• Whilst not actually a firearm as such, the term ‘six gun’ or ‘six shooter’ is a general, if inaccurate, description of a revolver. The original name came from the fact that the majority of the early revolvers had a cylindrical bullet magazine that held six rounds of ammunition.

• However, modern revolvers come in a variety of capacities including 5 round, 6 round, 8 round and 10 round. An example being the Smith & Wesson Model 617 is a 10 round capacity .22LR revolver shown below.

Six Million

• The Holocaust, also known by the Biblical word Shoah (which means calamity), was the mass murder or genocide of approximately six million Jews during World War II. Led by Adolf Hitler and the Nazi Party, it was part of a program of systematic state-sponsored murder by Nazi Germany throughout German-occupied territory.
• Of the nine million Jews who had resided in Europe before the Holocaust, approximately two-thirds were killed. Over one million Jewish children were killed in the Holocaust, as were approximately two million Jewish women and three million Jewish men.
• Some scholars argue that the mass murder of the Romani and people with disabilities should be included in the definition, and some use the term “holocaust” to describe other mass murders, including those of Soviet prisoners of war, Polish and Soviet civilians, and homosexuals. Recent estimates based on figures obtained since the fall of the Soviet Union indicates some ten to eleven million civilians and prisoners of war were intentionally murdered by the Nazi regime.
• The persecution and genocide were carried out in stages. Various laws to remove the Jews from civil society, most prominently the Nuremberg Laws, were enacted in Germany years before the outbreak of World War II. Concentration camps were established in which inmates were subjected to slave labor until they died of exhaustion or disease. Where Germany conquered new territory in eastern Europe, specialized units called Einsatzgruppen murdered Jews and political opponents in mass shootings. The occupiers required Jews and Romani to be confined in overcrowded ghettos before being transported by freight train to extermination camps where, if they survived the journey, most were systematically killed in gas chambers. Every arm of Germany’s bureaucracy was involved in the logistics that led to the genocides, turning the Third Reich into what one Holocaust scholar has called “a genocidal state”.
• There are numerous Holocaust Memorials throughout the world, including in Jerusalem, Washington, and Berlin, Germany.

.

• However, it was not the German Nazis, but the Croatian Ustase who were responsible for some of the most bloody and sadistic crimes carried out against the Orthodox population in Croatia. Some of their crimes so heinous that they even appalled the Nazis.
• The Ustaše committed their deeds in a bestial manner not only against males of conscript age, but especially against helpless old people, women and children. The number of the Orthodox that the Croats massacred and sadistically tortured to death has been estimated at approximately three hundred thousand.
• The legacy of the brutality of this genocidal campaign still affects the political situation in that part of Europe.

.

• Think it could never happen again? Don’t be too sure. In 1994 in Rwanda, Africa somewhere in the region of one million people were murdered by the Interahamwe death squads in a genocidal campaign. Local officials assisted in rounding up victims and making suitable places available for their slaughter. Tutsi men, women, children and babies were killed in thousands in schools. They were also killed in churches with the collusion of some clergy. The victims, in their last moments alive, were also faced by another appalling fact, namely that their cold-blooded killers were people they knew – neighbors, work-mates, former friends, sometimes even relatives through marriage.
