Significant Number Factoid Friday – Today The Number Is Twenty-Five 25

“Fight Against Stupidity And Bureaucracy”

.

It’s been a while since I did a number factoid.

My only excuse is the time it takes to compile these, which I haven’t managed to find for a few months, so if you missed them my apologies.

However, there is one today, so if you like this sort of thing I hope you enjoy.

In militaria

  • B-25 Mitchell
  • Named in honor of General Billy Mitchell, a pioneer of U.S. military aviation, the B-25 Mitchell was an American twin-engined medium bomber manufactured by North American Aviation that saw service over four decades. By the end of its production, nearly 10,000 B-25s in numerous models had been built.
  • It was used by many Allied air forces, in every theater of World War II, as well as many other air forces after the war ended, including The Royal Air Force (RAF), Royal Canadian Air Force, Royal Australian Air Force, Dutch Air Force, Soviet Air Force, China Air Force, Brazilian Air Force,  and by the Free French.

  • However, the incident for which the B-25 is perhaps best known is one that happened in America. At 9:40 on Saturday, 28 July 1945, a USAAF B-25D crashed in thick fog into the north side of the Empire State Building between the 79th and 80th floors.
  • Fourteen people died – eleven in the building and the three occupants of the aircraft including the pilot, Colonel William Smith.
  • Betty Lou Oliver, an elevator attendant, survived the impact and a subsequent uncontrolled descent in the elevator.
  • Partly as a result of this incident, Towers 1 and 2 of the World Trade Center were designed to withstand an aircraft impact. However, this design was based on an impact by a Boeing 707 aircraft in common use in the late 1960s and early 1970s, not the larger Boeing 767, two of which, (American Airlines Flight 11 and United Airlines Flight 175), struck the towers on September 11, 2001, resulting in their eventual collapse.

  • Boeing VC-25
  • The Boeing VC-25 is the United States Air Force designation for a military version of the Boeing 747 airliner. The A-model (VC-25A) is the only variant of the VC-25.
  • The VC-25 is most famous for its role as Air Force One, the call sign of any U.S. Air Force aircraft carrying the President of the United States. The two aircraft currently in U.S. service are highly modified versions of Boeing’s 747-200B, with tail numbers 28000 and 29000.
  • Although the Air Force One designation technically applies to the aircraft only while the President is aboard, the term is commonly applied to the VC-25s more generally.
  • They often operate in conjunction with Marine One helicopters that ferry the President to airports in circumstances where a vehicle motorcade would be inappropriate.

  • MIG-25
  • The Mikoyan-Gurevich MiG-25 is a supersonic interceptor and reconnaissance aircraft that was among the fastest military aircraft to enter service.
  • It was designed by the Soviet Union’s Mikoyan-Gurevich bureau. The first prototype flew in 1964, and the aircraft entered into service in 1970.
  • It has a top speed of Mach 2.83 (as high as Mach 3.2, but at risk of significant damage to the engines), and features a powerful radar and four air-to-air missiles.
  • When first seen in reconnaissance photography, the large wing planform suggested an enormous and highly maneuverable fighter. This was during a period of time when U.S. design theories were also evolving towards higher maneuverability due to combat performance in the Vietnam War.
  • The capabilities of the MiG-25 were better understood in 1976 when Soviet pilot Viktor Belenko defected in a MiG-25 to the United States via Japan. It turned out that the weight of the aircraft necessitated large wings.
  • Production of the MiG-25 series ended in 1984 after completion of 1,190 aircraft. A symbol of the Cold War, the MiG-25 flew with Soviet allies and former Soviet republics, remaining in limited service in Russia and several other nations.
  • It is the second fastest and second highest-flying military aircraft ever fielded after the SR-71 reconnaissance aircraft.

  • M25 “Three Shot Bazooka”
  • Bazooka is the common name for a man-portable recoilless antitank rocket launcher weapon, widely fielded by the United States Army. Also referred to as the “Stovepipe”, the innovative bazooka was among the first-generation of rocket propelled anti-tank weapons used in infantry combat.
  • Featuring a solid rocket motor for propulsion, it allowed for high-explosive anti-tank (HEAT) warheads to be delivered against armored vehicles, machine gun nests, and fortified bunkers at ranges beyond that of a standard thrown grenade or mine. The Bazooka also fired a HESH round, effective against buildings and tank armour.
  • The universally-applied nickname arose from the M1 variant’s vague resemblance to the musical instrument called a “bazooka” invented and popularized by 1930s U.S. comedian Bob Burns.

Significant Number Factoid Friday – Today The Number Is Twelve 12 (Part 1)

“Fight Against Stupidity And Bureaucracy”

.

Welcome to significant number factoid Friday.

Today the number is twelve and as usual it has a lot more associations that you might at first think. So many in fact that I have decided to split this post into two parts.

The second part (next Friday) will consist of the many entries in the ‘militaria’ section, while today’s will include the rest.

Even with the split it’s still a long post, but I hope those of you interested in numbers and their associations will enjoy reading it.

The Number Twelve  12

.

12

.

In religion

  • The number 12 is very important in many religions, mainly Judaism, Christianity, and Islam, but also found in some other belief systems.
  • From the Bible we know that Jacob had 12 sons, (Reuben, Simeon, Levi, Judah, Dan, Naphtali, Gad, Asher, Issachar, Zebulun, Joseph and Benjamin), who were the progenitors of the Twelve Tribes of Israel.
  • The New Testament describes twelve apostles of Jesus; after Judas Iscariot betrayed Jesus and hanged himself, a meeting was held (Acts) to add Matthias to complete the number twelve once more.
  • The Book of Revelation contains much numerical symbolism, and a lot of the numbers mentioned have 12 as a divisor.
  • Revelation 12:1 mentions a woman—interpreted as the people of Israel, the Church or the Virgin Mary—wearing a crown of twelve stars (representing each of the twelve tribes of Israel).
  • Also there are 12,000 people sealed from each of the twelve tribes of Israel, making a total of 144,000 (which is the square of 12 multiplied by a thousand).

.

  • The Church of Jesus Christ of Latter-day Saints has a Quorum of the Twelve Apostles.
  • In Orthodox Judaism, 12 signifies the age a girl matures (bat mitzvah)
  • There are 12 days of Christmas; the period of thirteen days including Epiphany is sometimes known as Christmastide, thus Twelfth Night is another name for the twelfth day of Christmas or January 5 (the eve of Epiphany).
  • Similarly, Eastern Orthodoxy observes 12 Great Feasts.
  • In Twelver (or Imami) Shi’a Islam, there are twelve Imams, successors of the prophet Muhammad. These twelve early leaders of Islam were—Ali, Hasan, Husayn, and nine of Husayn’s descendants. Imamah is the Shi‘ah doctrine of religious, spiritual and political leadership of the Ummah. The Shi‘ah believe that the A’immah (“Imams”) are the true Caliphs or rightful successors of Muhammad, and Twelver and Isma‘ili Shi‘ah further that Imams are possessed of supernatural knowledge, authority, and infallibility as well as being part of the Ahl al-Bayt, the family of Muhammad. Both beliefs distinguish the Shi‘ah from Sunnis.
  • In the Quran, the Sura number 12 is Sura Yusuf (Joseph), and it is located in Juz’a number 12. This Sura narrates the story of Prophet Yusuf and his 12 brothers.
  • In Hinduism, the sun god Surya has 12 names. Also, there are 12 Petals in Anahata (Heart Chakra. There are twelve “Jyotirlingas” in Hindu Shaivism. The Shaivites (orthodox devotees of God Shiva) treat them with great respect and they are visited by almost every pious Hindu at least once in a lifetime.

.

  • In antiquity there are numerous magical/religious uses of twelves.
  • Ancient Greek religion, the Twelve Olympians were the principal gods of the pantheon.
  • Greek mythology has the twelve labors of Hercules.
  • The chief Norse god, Odin, had 12 sons.
  • Several sets of twelve cities are identified in history as a dodecapolis, the most familiar being the Etruscan League.

  • The human body has twelve cranial nerves.
  • The duodenum (from Latin duodecim, “twelve”) is the first part of the small intestine, that is about twelve inches (30 cm) long. More precisely, this section of the intestine was measured not in inches but in fingerwidths. In fact, in German the name of the duodenum is Zwölffingerdarm and in Dutch the name is twaalfvingerige darm, both meaning “twelve-finger bowel”.
  • Vitamin B12, also called cobalamin, is a water-soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is one of the eight B vitamins. The vitamin is the largest and most structurally complicated vitamin and can be produced industrially only through bacterial fermentation-synthesis.
  • Dichlorodifluoromethane (R-12), a colorless gas usually sold under the brand name Freon-12, is a chlorofluorocarbon halomethane (CFC), used as a refrigerant and aerosol spray propellant. Complying with the Montreal Protocol, its manufacture was banned in the United States along with many other countries in 1996 due to concerns about damage to the ozone layer. It is soluble in many organic solvents. Dichlorodifluoromethane was also the main component of Silly String.

  • Apollo 12
  • Apollo 12 was the sixth manned flight in the United States Apollo program and the second to land on the Moon (an H type mission).
  • It was launched on November 14, 1969 from the Kennedy Space Center, Florida, four months after Apollo 11. Mission commander Charles “Pete” Conrad and Lunar Module Pilot Alan L. Bean performed just over one day and seven hours of lunar surface activity while Command Module Pilot Richard F. Gordon remained in lunar orbit. The landing site for the mission was located in the southeastern portion of the Ocean of Storms.
  • Unlike the first landing by Apollo 11, Conrad and Bean achieved a precise landing at their expected location, the site of the Surveyor 3 unmanned probe, which had landed on April 20, 1967. They carried the first color television camera to the lunar surface on an Apollo flight, but transmission was lost after Bean accidentally destroyed the camera by pointing it at the Sun. On one of two moonwalks, they visited the Surveyor, and removed some parts for return to Earth.
  • The mission ended on November 24 with a successful splashdown.

  • STS-12 
  • During the Space Shuttle program, several missions were cancelled. Many were cancelled as a result of the Challenger and the Columbia disasters. Many early missions were cancelled due to delays in the development of the shuttle. Others were cancelled because of changes in payload and missions requirements.
  • STS-12 was originally scheduled for launch on 30 January 1981. The crew of three were to place the satellites TDRS-C and Anik-C2 into orbit during the 2-day mission. An alternate mission was also planned which replaced the TDRS-C with an Intelsat-V satellite, and would last five days instead of two. TDRS-C was eventually made as the replacement for the destroyed TDRS-B and launched from Discovery on STS-26 in September 1988.
  • The crew of STS-12 were, Henry W. Hartsfield, Jr. (Commander); Michael L. Coats (Pilot); and Mission Specialists Richard M. Mullane, Steven A. Hawley and Judith A. Resnik.

  • Majestic 12
  • According to UFO conspiracy theory, Majestic 12 (or MJ-12) is the supposed code name of an alleged secret committee of scientists, military leaders, and government officials, formed in 1947 by an executive order by U.S. President Harry S. Truman. The purpose of the committee was to investigate the recovery of a UFO north of Roswell, New Mexico during July 1947.
  • Initial indications of such a group’s existence appeared in 1978 in declassified Canadian documents. Another reference to a classified group called “MJ-12” was discovered in 1980, but was later identified to be a hoax. In 1984 a set of documents was discovered in United States archives, which closely resemble real declassified documents, but which the FBI have declared to be “completely bogus”.
  • UFO conspiracy theories and the popular media based on them sometimes incorporate Majestic 12.

In politics

  • The 12th President of the United States of America (1849–1850) was Zachary Taylor (November 24, 1784 – July 9, 1850). An American military leader, his 40-year military career ended with far-reaching victories in the Mexican–American War. His status as a national hero won him election to the White House despite his vague political beliefs. His top priority as president was preserving the Union, but he died 16 months into his term, before making any progress on the status of slavery, which had been inflaming tensions in Congress.

In transport

  • Lockheed Model 12 Electra Junior
  • The Lockheed Model 12 Electra Junior, more commonly known as the Lockheed 12 or L-12, is an eight-seat, six-passenger all-metal twin-engine transport aircraft of the late 1930s designed for use by small airlines, companies, and wealthy private individuals.
  • A scaled-down version of the Lockheed Model 10 Electra, the Lockheed 12 was not popular as an airliner but was widely used as a corporate and government transport. Several were also used for testing new aviation technologies.
  • Aviator Milo Burcham flew a Lockheed 12A in the 1937 Bendix Trophy Race from Burbank, California to Cleveland, Ohio. This 12A had been modified with extra fuel tanks in the cabin, allowing it to save time by making the entire 2,043-mile (3,288 km) trip non-stop. The 12A came in fifth at an average speed of 184 mph (296 km/h); this was an impressive performance, since the first and fourth-place winners were both privately owned Seversky P-35 fighters.
  • Another Lockheed 12A, owned by Republic Oil Company and named The Texan, was modified by aviator Jimmie Mattern for a round-the-world flight attempt. Mattern filled the 12A’s cabin with fuel tanks and removed the cabin windows and door; the crew would enter the aircraft via a cockpit hatch. The aircraft was denied a U.S. permit for the flight following the Earhart incident (she had been flying a Lockheed 10 Electra), however it was pressed into action September 1937 in a long range search effort for Sigizmund Levanevsky who crashed somewhere between the North pole and Barrow, Alaska. “The Texan” was outfitted as a luxury transport afterward, and lost in a hangar fire in January 1938.

  • Renault 12
  • The Renault 12 is a family car produced by French automaker Renault between 1969 and 1980. Available as a saloon (Berline) and estate (Break), it was also produced under license in many countries across the globe into the early 21st century.
  • In its first few years the 12 received praise from the European press for its spacious, comfortable interior, its styling, its performance and its low fuel consumption. However it fared worse in the North American press: in a test of the 1974 model, Road & Track was critical of the engine’s “obtrusive” noise, and called the heavy, non-power steering “a serious design flaw”. They also gave it “very poor marks” for the ventilation system.
  • Renault 12 production and sales ended in western Europe in 1980, but the model continued to be produced and sold by Renault affiliates elsewhere. The last R12 was produced in 1999 in Turkey, whilst Romanian automaker Dacia continued producing the R12-based 1310 sedan and estate until 2004 and the R12-based Dacia Pick-Up until December 2006.
  • In terms of sales the Renault 12 was a successful car, selling 2.5 million units.

  • Vector M12
  • The Vector M12 was a vehicle designed by parent company Megatech LTD the Vector Motors Corporation, and was the first vehicle produced after the hostile takeover of the company from Jerry Wiegert by the Indonesian company Megatech.
  • The vehicle was a rebodied Lamborghini Diablo with a chopper gun fiberglass body set on a lengthened Diablo chassis. It was a loose copy of the Vector AWX-3, which was not released due to the Megatech hostile takeover.
  • The M12 was able to accelerate from zero to 60 mph (97 km/h) in 4.8 seconds and had a top speed of 189 mph (304 km/h) and was produced from 1995 to 1999, when production was halted, partly due to slow sales of the cars and alleged mismanagement of the company.
  • The average price of the vehicle was $184,000 (USD). Today you can purchase a M12 normally for $65,000 to an astounding $189,000 paid by a purchaser of a purple M12 at Barrett Jackson for a record sale price.

  • Noble M12       
  • The Noble M12 is a two-door, two-seat model, originally planned both as a coupe and as a convertible.
  • All M12s have been powered by modified bi-turbocharged Ford Duratec V6 engines. The M12 has a full steel roll cage, steel frame, and G.R.P. (fibreglass) composite clam shell body parts.
  • These famed “Ferrari killers” are extremely lightweight and stiff. Although looking to be track derived, the M12 performs very well on both road and track, with surprisingly good ride quality, but a rigid feel. This is achieved by having no anti-roll bars on the car. This allows the suspension to be stiff yet comfortable.

  • Spyker E12 Zagato
  • Spyker Cars shareholder and CEO, Victor Muller hinted at a Maserati Quattroporte, Porsche Panamera rival with an eight-cylinder (the E8) or a twelve-cylinder (the E12) engine, but due to problems getting the D8 into production, the idea was ignored until recently when Muller has said he “believes now could be the time to resurrect the saloon.”
  • Muller believes it will take about four years from time E8/E12 is revealed to the time it starts production. In March 2011, Muller stated that the production version of the Spyker E8/E12 will use a twelve-cylinder instead of the proposed eight-cylinder engine.

  • V12 engine
  • A V12 engine is a V engine with 12 cylinders mounted on the crankcase in two banks of six cylinders, usually but not always at a 60° angle to each other, with all 12 pistons driving a common crankshaft.
  • Since each cylinder bank is essentially a straight-6, this configuration has perfect primary and secondary balance no matter which V angle is used and therefore needs no balance shafts. A V12 with two banks of six cylinders angled at 60°, 120° or 180° (with the latter configuration usually referred to as a flat-12) from each other has even firing with power pulses delivered twice as often per revolution as a straight-6.
  • This allows for great refinement in a luxury car. In a racing car, the rotating parts can be made much lighter and thus more responsive, since there is no need to use counterweights on the crankshaft as is needed in a 90° V8 and less need for the inertial mass in a flywheel to smooth out the power delivery. In a large displacement, heavy-duty engine, a V12 can run slower than smaller engines, prolonging engine life.

  • W12 engine
  • A W12 engine is a twelve cylinder piston internal combustion engine in a W configuration.
  • W12 engines are manufactured in two distinct configurations. One configuration uses four rows of three cylinders merged into two ‘cylinder banks’ (two narrow-angle VR6 engine blocks), coupled to a common crankshaft – as in the Volkswagen Group W12. Another uses three banks of four cylinders coupled to a common crankshaft – as in the Napier Lion.

  • STS-40
  • Although designated STS-40, this was in fact the 41st flight of the Space Shuttle and the 11th flight of Columbia. Its mission was to conduct the Spacelab Life Sciences (SLS-1) experiments, the first spacelab dedicated to life sciences research. This included experiments that explored how the heart, blood vessels, lungs, kidneys and hormone-secreting glands respond to microgravity, the causes of space sickness and changes in muscles, bones and cells during the microgravity environment of space flight and in the readjustment to gravity upon returning to Earth.
  • Launch took place on June 5, 1991, 9:24:51 a.m. EDT. It was originally set for May 22,1991, but postponed less than 48 hours before launch when it became known that a leaking liquid hydrogen transducer in orbiter main propulsion system which was removed and replaced during a leak testing in 1990, had failed an analysis by vendor. Engineers feared that one or more of the nine liquid hydrogen and liquid oxygen transducer protruding into fuel and oxidizer lines could break off and be ingested by the engine turbopumps, causing engine failure.
  • In addition, one of orbiter five general purpose computers failed completely, along with one of the multiplexer demultiplexers that control orbiter hydraulics ordinance and orbiter maneuvering system / reaction control system functions in aft compartment.
  • New general purpose computer and multiplexer demultiplexer were installed and tested. One liquid hydrogen and two liquid oxygen transducers were replaced upstream in propellant flow system near 17-inch disconnect area, which is protected by internal screen. Three liquid oxygen transducers replaced at engine manifold area, while three liquid hydrogen transducers here were removed and openings plugged. Launch reset for 8 a.m. EDT, June 1, but postponed again after several attempts to calibrate inertial measurement unit 2 failed. Unit was replaced and retested, and launch was rescheduled for June 5. Launch Weight: 251,970 lbs.
  • The Commander STS-40 was Marine Corps Col. Bryan D. O’Connor. Other crew, Air Force Lt. Col. Sidney M. Gutierrez (Pilot), James P. Bagian, M.D.; Tamara E. Jernigan, Ph.D.; and Margaret Rhea Seddon, M.D. The payload specialists, Francis Andrew Gaffney, M.D., and Millie Hughes-Fulford, Ph.D.

  • Ronald Reagan, former actor and Governor of California (1967-75) was the fortieth President of the United States of America, from January 20, 1981 to January 20, 1989. His Vice President was George H. W. Bush.

  • Reagan’s Presidency was notable for at least two incidents.
  • On March 30, 1981, only 69 days into the new administration, Reagan, his press secretary James Brady, Washington police officer Thomas Delahanty, and Secret Service agent Timothy McCarthy were struck by gunfire from would-be assassin John Hinckley, Jr. outside the Washington Hilton Hotel. Although “close to death” during surgery, Reagan recovered and was released from the hospital on April 11, becoming the first serving U.S. President to survive being shot in an assassination attempt. The attempt had great influence on Reagan’s popularity; polls indicated his approval rating to be around 73%. Reagan believed that God had spared his life so that he might go on to fulfill a greater purpose.
  • A couple of videos, the first rather long but interesting in that it shows the live story of the assassination attempt developing, and the second President Reagan recounting the assassination attempt from his personal perspective.

  • Another controversial incident involving President Reagan happened in summer of 1981 when PATCO, the union of federal air traffic controllers, went on strike, violating a federal law prohibiting government unions from striking. Reagan declared the situation an emergency as described in the 1947 Taft–Hartley Act, and stated that if the air traffic controllers “do not report for work within 48 hours, they have forfeited their jobs and will be terminated”. They did not return and on August 5, Reagan fired 11,345 striking air traffic controllers who had ignored his order, and used supervisors and military controllers to handle the nation’s commercial air traffic until new controllers could be hired and trained. As a leading reference work on public administration concluded, “The firing of PATCO employees not only demonstrated a clear resolve by the president to take control of the bureaucracy, but it also sent a clear message to the private sector that unions no longer needed to be feared.”

In sport

  • In football (soccer), forty is generally considered to be the number of points that a Premier League team (or, by extension, a team in any 20-team league with a standard home-and-away season) needs to avoid relegation.
  • In baseball, each team in Major League Baseball is allowed to have 40 players under major-league contracts at any given time (not including players on the 60-day disabled list). From September 1 to the end of the regular season, teams are allowed to expand their game-day rosters to include the entire 40-man roster.
  • In tennis, the number 40 represents the third point gained in a game. A score of 40-40 (three points each) is called “deuce”, at which time a player must score two consecutive points to win the game.

  • Beginning with the 2013 season, forty cars will run each race in NASCAR’s second-level Nationwide Series.
  • The jersey number 40 has been retired by several North American sports teams in honor of past playing greats or other key figures:
  • In Major League Baseball: the Houston Astros, for Don Wilson; the Pittsburgh Pirates, for Danny Murtaugh, most noted as the team’s longtime manager.

  • Curtiss P-40 Warhawk
  • Manufactured by Curtiss-Wright Corporation of Buffalo, New York and designed by Donovan Berlin, the Curtiss P-40 Warhawk’s first flight was on 14 October 1938. Over 13,700 were built and during its twenty year life it was used by the United States Army Air Forces, the Royal Air Force, Royal Australian Air Force, Royal Canadian Air Force, Royal New Zealand Air Force, and many others. A single-engine, single-seat, all-metal fighter and ground attack aircraft, it was used extensively by most Allied powers during World War II, and remained in front line service until the end of the war.
  • The British Commonwealth and Soviet air forces used the name Tomahawk for models equivalent to the P-40B and P-40C, and the name Kittyhawk for models equivalent to the P-40D and all later variants.

  • PPD40
  • The PPD (Pistolet-Pulemyot Degtyarova) was developed by famous Russian small arms designer Fedor Degtyarov. It was formally adopted by the Red Army in 1935 and entered limited production as the PPD-34. Made in small numbers, it was mostly relegated for NKVD use, mostly for border guards. Slightly modified in 1938, it was then produced until 1939 in PPD-34/38 variation, with newly developed 71 rounds drum with long neck.
  • After the Winter War experience (1940 war between USSR and Finland), new version of PPD has been rapidly developed, with the most visible change being the two-part stock, cut to accept new pattern of drums, which had no neck. This became the PPD-40.
  • After the outbreak of the Great Patriotic Warin 1941, it was soon been discovered that the PPD-40 is less than ideal for wartime production, so it was quickly replaced by the more efficient and inexpensive PPSh-41, which appeared in great numbers and was widely used by Red Army.

  • MP40
  • One of the most famous submachine gun designs in history, the M.P. 38 submachine gun started its life under requirements from German Heereswaffenamt (HWA, Army Weapons Office), which saw the need for a compact submachine gun, suitable for use by armored vehicles crews and paratroopers.
  • German arms-making company Erfurter Maschinenfabrik Gmbh, better known under its trade name Erma, began the development of a new weapon under HWA specifications. It was manufactured for just 2 years, when it was replaced in production by externally similar, but less expensive MP-40, which used more stamped parts instead of machined parts, found in MP-38.
  • There also were minor variations in design of MP-38, such as shape of cocking handle etc. MP-40 was also produced in a number of variations, which differed in shape of certain parts; also, toward the end of the war, several production shortcuts were introduced to save the costs of manufacturing. probably the most interesting variation of the MP-40 were the MP-40-II and MP-40-II. These guns featured dual magazine housings which hold two magazines in a laterally sliding bracket. This increase the total ammunition capacity “in the gun” to 64 rounds, in a desperate attempt to catch up with 71-round magazine capacity of Soviet PPSh-41. The later variant, MP-40-II, was made in limited numbers, but turned out to be a failure – sliding dual-magazine housing was a constant source of jams and failures, and was very sensitive to dirt and fouling.
  • Nevertheless, the MP-40 submachine guns were of good design, and set the pattern for so called “second generation” of submachine guns (“first generation” being represented by the wood-stocked and carefully machined MP-18, MP-28 and the like). The second generation weapons usually were of compact design, and made using mostly steel stampings and pressings, or castings.
  • Many MP-40 that survived the WW2, continued to serve up until late 1970s or early 1980s, in few European armies such as Austrian or Norwegian.

  • Taurus MP40
  • During the 1990s Taurus replaced in production its MT-12A submachine gun (licensed copy of the Beretta PM-12) with another foreign design, this time purchased from Chile.
  • Originally known as the FAMAE SAF, in Brazil it is made in a slightly modified form as the Taurus MT-9 (in 9mm Luger) and MT-40 (in .40SW, especially for the Brazilian police forces that favor this caliber). In this case, the MT index stands for Metralhadora Taurus – Taurus Submachine gun, and the digits denote a caliber.
  • Taurus also makes an interesting offshoot of the MT-40, the CT-40 semi-automatic carbine, which is also intended for police and security use but is restricted to semi-automatic fire and has somewhat longer barrel.

  • SVT-40
  • The SVT-38 (Samozaryadnaya Vintovka Tokareva – Tokarev Self-loading rifle) was originally adopted in the 1938 after more than 20 years of the research and development, done by famous Russian arms designer Fedor Tokarev. 
  • This rifle was made in relatively large numbers (more than 1 million made prior to 1945), and was originally issued as a standard infantry rifle, replacing the obsolete Mosin-Nagant M1891/30 bolt action rifles. A few SVT-40 were also manufactured in the sniper variant, (only about 50 000) equipped with scope mounts and telescopic sights, but accuracy was not sufficient. 
  • The SVT-40 had a somewhat controversial reputation. It was highly regarded by the enemies (Finns and Germans) and it was a very sought-after war trophy, re-issued to both German and Finnish troops. On the other hand, it was often considered unreliable and over-complicated by the Soviet troops (when comparing with old Mosin-Nagant rifles), but it was more to the poor training and maintenance, than to the rifle itself. Some better trained and educated Soviet troops, such as Sea Infantry (Marines, which always were some kind of elite in the Soviet army) used the SVT-40 with great deal of success.

  • Husqvarna M/40
  • The ‘Luger-like’ L-35 pistol was developed by the Finnish designer Aimo Lahti and manufactured by Finnish company VKT from 1935 until 1985 or so. It was adopted as a standard sidearm for Finnish army in 1935. 
  • In 1940, Sweden purchased a license for Lahti pistol, simplified it and began production as a Husqvarna M/40 pistol. Due to simplification and poor quality of steel used in M/40, these guns tended to crack when fired 9mm “submachinegun” ammunition, and also M/40 were less reliable than original L-35s, so in the 1980s almost all M/40s were recalled from military service and replaced by older m/07 pistol (licensed Browning M1903 pistols) as an emergency feature.

  • HK-UMP40
  • The UMP (Universal Machinen-Pistole = Universal Submachine Gun) had been developed by the Heckler & Koch company of Germany in the mid- to late- 1990s and first appeared on the markets in 1999. The key idea behind the UMP was to create a lightweight and powerful submachine gun, that was also cheaper than one of the H&K’s flagships, the MP-5. UMP, being targeted primary for USA law enforcement market, first appeared in .45ACP and .40SW chamberings, and later – in 9mm. 
  • The UMP is a blowback-operated select-fire submachine gun, being fired from the closed bolt. The receiver is made from the polymer, the controls are fully ambidextrous. UMP can be fired in full-auto, in single shots, and in 2 or 3 round bursts (optional). UMP also has bolt hold-open device, which traps the bolt in the open position when the last round from magazine had been fired. UMP has side-folding buttstock and two set of picatinny rails – one on the top of the receiver, and the other – on the forend. These rails can accept wide variety of sighting and other equipment, such as red-dot sights, laser pointers, tactical grips and flashlights. The barrel has quick mount for snap-on silencer.

And finally,

Last, but definitely not least, perhaps one of the greatest ever inventions also carries the ’40’ tag. It is WD-40.

WD-40 is the trademark name of a penetrating oil and water-displacing spray, developed in 1953 by Norm Larsen, founder of the Rocket Chemical Company, in San Diego, California.

The term ‘WD-40’, is an abbreviation of the phrase “Water Displacement, 40th formula”.

Larsen was attempting to create a formula to prevent corrosion in nuclear missiles, by displacing the standing water that causes it. He claims he arrived at a successful formula, which is primarily composed of various hydrocarbons, on his 40th attempt.

WD-40 was first used by Convair to protect the outer skin, and more importantly, the paper thin “balloon tanks” of the Atlas missile from rust and corrosion.

WD-40 first became commercially available on store shelves in San Diego in 1958

Significant Number Factoid Friday – Today The Number Twenty-Three 23

“Fight Against Stupidity And Bureaucracy”

 .

They’ve been ‘beautiful’,  they’ve been ‘big’  and they’ve been ‘unusual’.  Today we have ‘significant’ number, twenty-three, 23, so-called because of its use and the beliefs surrounding it.

Enjoy.

 

Twenty-three

23 sign

Until the recent Jim Carey movie that highlighted the Discordian fascination with the idea that everything that happens on earth and in all of existence is somehow related to the number 23, that number was really only of significance to a few conspiracy theorists.

Jim Carey movie '23'

Discordia is a rather rare belief that is based on the study of random events and numbers. The number 23 is sacred because it belongs to a Greek Goddess named Eris. She is the Goddess of Chaos and her followers practice a form of ritual worship called chaos magic.

 

In Religion

  • Although the Old Testament is unspecific, it is widely held that Adam and Eve had 23 daughters;
  • The 23rd verse of the first chapter of Genesis brings the act of creation to a close;
  • the 23rd chapter of the book of Genesis deals entirely with death, namely that of Abraham’s wife, Sarah;
  • The 23rd Psalm alao known as ‘the psalm of David’, and even better known to many by its first line ‘The Lord Is My Shepherd’ is the most famous and most quoted of the Psalms;
  • The Ancient Egyptians hailed the New Year on July 23 – the day Sirius rises behind the sun;
  • According to ancient Mayan prophesy on December 23, 2012 the world will end;
  • In Islam, the Qur’an was revealed in a total of 23 years to Muhammad;
  • Muslims believe the first verses of the Qur’an were revealed to the Islamic prophet Muhammad, on the 23rd night of the 9th Islamic month.

 

 

In Maths

  • 23 is the lowest prime that consists of consecutive digits that are also primes;
  • Prime numbers have been described as being the building blocks of the world of numbers and therefore also the building blocks of the reality that we experience;
  • The Birthday Paradox states that a group of 23 randomly-selected people is the smallest number where there will be a probability higher than 50 per cent that two people will share the same birthday.

In Metaphysics

  • The number 23 has also been studied by many great metaphysicists, including Robert Shea and Robert Anton Wilson who wrote three books about the number. The number is seen by these authors as being the key to illumination and they also claim that major shifts in collective consciousness and world events can be seen in each cycle of 23 years.

 

In Love

  • Twenty three is also a significant number in love. This is because in ancient China, the number two was assigned a feminine role and the number three was given a masculine role. The number 23 then became to symbolize marriage, procreation, and progeny.

 love 23

In Psychology

  • The great psychologist and anthropologist Carl Jung also thought that the number 23 was special and defined it as a number of synchronicity.

 

In Politics

  • The 23rd President of the United States was Benjamin Harrison (1833–1901). Served as President from March 4, 1889 to March 4, 1893.   Party – Republican.  VP – Levi P. Morton;

  •  The Twenty-third Amendment (Amendment XXIII) to the United States Constitution permits citizens in the District of Columbia to vote for Electors for President and Vice President. The amendment was proposed by Congress on June 17, 1960, and ratified by the states on March 29, 1961. The first Presidential election in which it was in effect was the presidential election of 1964. Prior to the passage of the amendment, residents of Washington, D.C. were forbidden from voting for President or Vice President as the District is not a U.S. state. However, they are still unable to send voting Representatives or Senators to Congress.

 

In Space

  • The tilt of Earth’s axis is roughly 23o accounting for the changing seasons and the procession of the Zodiac;
  • The first Apollo landing on the moon was at 23.63 degrees east; the second was 23.42 degrees west;
  • On July 23, 1996 the “Mysterious Eyes” of comet Hale-Bopp are first sighted.

 

In Militaria

  • The most famous aircraft with the 23 designation is the Russian Mikoyan-Gurevich MiG-23 also known by the NATO reporting name ‘Flogger’.
  • It is a third generation variable-geometry fighter aircraft, and was the first attempt by the Soviet Union to design look-down/shoot-down radar and one of the first to be armed with beyond visual range missiles. It was also the first MiG production fighter aircraft to have intakes at the sides of the fuselage.
  • Production started in 1970 and reached large numbers with over 5,000 aircraft built. Today the MiG-23 remains in limited service with various export customers.

  • In America, the Northrop YF-23 or Northrop–McDonnell Douglas YF-23 was a less commercially successful single-seat, twin-engine fighter aircraft designed for the United States Air Force (USAF). The design was a finalist in the USAF’s Advanced Tactical Fighter (ATF) competition, battling the Lockheed YF-22 (developed by Lockheed, Boeing and General Dynamics) for a production contract. Two YF-23 prototypes were built with the nicknames “Black Widow II” and “Gray Ghost”.
  • Although the YF-23 was stealthier and faster, but less agile than its competition. After a four-year development and evaluation process, the YF-22 was announced the winner in 1991 and entered production as the Lockheed Martin F-22 Raptor.
  • The U.S. Navy considered using the production version of the ATF as the basis for a replacement to the F-14, but these plans were later canceled. As of 2009, the two YF-23 prototypes were museum exhibits.

  • On the ground the Soviet ZU-23-2 anti-craft gun was developed in the late 1950s. It was designed to engage low-flying targets at a range of 2.5 km as well as armoured vehicles at a range of 2 km and for direct defense of troops and strategic locations against air assault usually conducted by helicopters and low-flying airplanes.
  • In the Soviet Union, some 140,000 units were produced. The ZU-23 has also been produced under licence by Bulgaria, Poland, Egypt and the People’s Republic of China.
  • Development of this weapon into a self-propelled anti-aircraft gun (SPAAG) led to the ZSU-23-4 Shilka. (see below)
The ZU-23-2 in Saint Petersburg

  • However, the best known piece of ground militaria is probably the  ZSU-23-4 “Shilka” is a lightly armored, self-propelled, radar guided anti-aircraft weapon system. The acronym “ZSU” stands for Zenitnaya Samokhodnaya Ustanovka, meaning “anti-aircraft self-propelled mount”. The “23” signifies the bore diameter in millimeters; the “4” signifies the number of gun barrels.
  • It is named after the Russian Shilka River. Afghan soldiers nicknamed it maszyna do szycia (sewing machine) due to the sound of firing guns and because of the similarity of the name “Shilka” to the Russian word meaning “to sew”). It is also referred to by its nickname of “Zeus”.

While Burroughs was thinking about the incident, a radio bulletin announced the crash of a Flight 23 on the New York-Miami route. The pilot was another Captain Clark. The events prompted an obsession which saw Burroughs record every occurrence of the number 23 for the rest of his life.
