Significant Number Factoid Friday – Today The Number Is Eighty-Four 84

“Fight Against Stupidity And Bureaucracy”


Time for another significant number factoid.

Today the number is 84.

As usual there is a lot more to it than you might have thought.

If you are into numbers, facts, trivia, or you just like the number 84 then this is for you.



84 .

In religion

  • 84 occurs in the Bible 2 times and once as part of other numbers: — Luke, 2.37 and Nehemiah, 11.18
  • 84th Book of Enoch describes the Dream Visions told to Methuselah.



In Mathematics

  • 84 is the sum of the first seven triangular numbers (making it a tetrahedral number), as well as the sum of a twin prime (41 + 43).
  • You can count the number 84 in two different ways in this figure. There are 84 diamond-shaped tiles to make this 2-dimensional pattern. Or you can build a 3-dimensional pyramid with 84 blocks.


  • A hepteract is a seven-dimensional hypercube with 84 penteract 5-faces.
  • The Greek-based numeric prefix octacontatetra- means 84.
  • The Latin-based numeric prefix quattuoroctoginta- means 84.
  • The Roman numeral for 84 is LXXXIV.



In Science

  • 84 is the Atomic Weight of Krypton, a noble gas and is present in the air at about 1 ppm. The atmosphere of Mars contains a little (about 0.3 ppm) of krypton. It is characterized by its brilliant green and orange spectral lines.


  • 84 is the Atomic Number of Polonium, discovered in 1898 by Marie and Pierre Curie. It is a silvery metal, that has more isotopes than any other element, all of which are radioactive. Polonium has been found in tobacco as a contaminant and in uranium ores.
  • Polonium has been used as an assassin’s weapon, notably, in the murder of Alexander Litvinenko, a Russian dissident, in 2006. According to Prof. Nick Priest of Middlesex University, an environmental toxicologist and radiation expert, speaking on Sky News on December 2, Litvinenko was probably the first person ever to die of the acute a-radiation effects of 210Po.

  • It has also been suggested that Irène Joliot-Curie was the first person to die from the radiation effects of polonium. She was accidentally exposed to polonium in 1946 when a sealed capsule of the element exploded on her laboratory bench. In 1956 she died from leukemia.
  • According to the book The Bomb in the Basement, several death cases in Israel during 1957–1969 were caused by 210Po. A leak was discovered at a Weizmann Institute laboratory in 1957. Traces of 210Po were found on the hands of professor Dror Sadeh, a physicist who researched radioactive materials. Medical tests indicated no harm, but the tests did not include bone marrow. Sadeh died from cancer. One of his students died of leukemia, and two colleagues died after a few years, both from cancer. The issue was investigated secretly, and there was never any formal admission that a connection between the leak and the deaths had existed.
  • Abnormally high concentrations of 210Po have been detected in July 2012 in clothes and personal belongings of the Palestinian leader Yasser Arafat, who died in 2004 of uncertain causes. However, the spokesman for the Institut de Radiophysique in Lausanne, Switzerland, where those items were analyzed, stressed that the “clinical symptoms described in Arafat’s medical reports were not consistent with polonium-210 and that conclusions could not be drawn as to whether the Palestinian leader was poisoned or not”, and that “the only way to confirm the findings would be to exhume Arafat’s body to test it for polonium-210.” On 27 November 2012 Arafat’s body was exhumed and samples were taken for separate analysis by experts from France, Switzerland and Russia. Results are expected by April 2013.

  • USS Constitution
  • The USS Constitution is one of the first six frigates of the U.S. Navy, built by the Naval Act of 1794. These frigates were designed by Joshua Humphreys who designed them to be the major vessels of the young U.S. Navy. For this reason, the Constitution and the others were designed and built bigger, stronger and better armed than the rest of the frigates of the period.
  • Initially she was commissioned to provide protection for merchant ships of the United States during the Quasi-War with France, and fight the Barbary Pirates of Tripoli during the War. However, the Constitution is most famous for her actions during the War of 1812 between the United States and Britain, when she captured numerous merchant ships and defeated five warships from Britain: HMS Guerriere, HMS Java, HMS Pictou, HMS Cyane and HMS Levant.
  • In the battle with Guerriere she earned the nickname “Old Ironsides” and the public respect and affection that often saved her from being dismantled. This frigate has actively served the United States through the years, and either as flagship in the Mediterranean squadrons and Africa, sailed around the world in 1840. During the Civil War she served as a training ship for the Naval Academy.
  • Nowadays Constitution’s mission is to promote understanding of the role of the Navy in times of war as in time of peace through educational outreach, historical demonstrations and active participation in public events. This ship is active, and as such, its crew of 60 officers and sailors members, participates in ceremonies, educational programs and special events while keeping the ship open to visitors year round offering free tours. All personnel assigned is an active member of the Navy and the allocation to this crew is considered a special duty. Traditionally, the command of the ship is assigned to a Navy commander.
  • She is to date the oldest ship still afloat and is active worldwide.

  • USS Bulkeley (DDG-84)
  • USS Bulkeley (DDG-84) is an Arleigh Burke-class destroyer in the United States Navy. She was named after Vice Admiral John D. Bulkeley, who was a World War II Medal of Honor recipient.
  • Bulkeley was laid down on 10 May 1999 by Ingalls Shipbuilding and launched on 21 June 2000 in Pascagoula, Mississippi. She was commissioned on 8 December 2001 and is currently homeported at Naval Station Norfolk, Virginia.
  • In February 2011, the Bulkeley was involved in a mission to rescue four American citizens from the yacht Quest which was attacked by Somali pirates.
  • On 5 March 2011, Bulkeley was involved in rescuing a Japanese oil tanker, MV Guanabara, from Somali pirates while on duty with Combined Task Force 151 off the coast of Oman. Three of the pirates were tried and convicted in Japan, the fourth was turned over to juvenile authorities, as it was determined that he was a minor.
  • On 16 May 2011 the Bulkeley responded to a mayday call from the Panamanian flagged very large crude carrier Artemis Glory by dispatching a Blackhawk helicopter to its position. Seeing that a piratical skiff carrying four men was firing upon the Artemis Glory, the Blackhawk engaged the skiff. After killing its four crewmembers, the helicopter withdrew without any casualties to its own crewmembers or that of the Artemis Glory.
  • The ship returned to Norfolk on 15 July 2011. During its deployment, it had participated in operations which had captured 75 Somali pirates and had missile strikes by its carrier strike group against the Libyan government.

  • No. 84 Squadron
  • No. 84 Squadron of the Royal Flying Corps (RFC) was formed on 7 January 1917 and moved to France in September 1917. It flew the SE.5 over the Western front, at one time based in Bertangles, France until it returned to the UK in August 1919. The squadron was disbanded on 30 January 1920. Its aces included Walter A. Southey.
  • The squadron was reformed on 13 August 1920 at Baghdad in Iraq, moving to Shaibah in September, where it remained for the next 20 years. Its initial equipment was DH.9As (until January 1929) and these were replaced by Wapitis (beginning October 1928), Vincents (December 1934) and Blenheims Mk.Is ( February 1939), before moving to Egypt in September 1940. It later operated in Greece, Iraq, and the Western Desert before moving briefly to the Far East. No. 84 Squadron flew the Vultee Vengeance dive bomber from Assam in North-East India but, contrary to some reports, not the Commonwealth Boomerang fighter from New Guinea during World War II (this was done by No. 84 Squadron RAAF). The squadron re-equipped with the Mosquito in February 1945 and in September 1945 with the Bristol Beaufighter. In 1949 No. 84 Squadron flew Bristol Brigands during Operation Firedog.
  • The squadron was disbanded again on 20 February 1953, but 204 Squadron was renumbered to No. 84 Squadron on the same day. The squadron was the transport squadron for the RAF in the Middle East till 1971. Its Vickers Valetta flight was detached to become No. 233 Squadron RAF on 1 September 1960 at RAF Khormaksar to provide general transport for the British Army in the Aden Protectorate. The squadron was disbanded yet again at Muharraq on 31 October 1971.
  • The squadron was reformed on 17 January 1972 from 1563 Flt and a detachment from 230Sqn with Westland Whirlwind HAR.10s at RAF Akrotiri to aid UN operations and operate search and rescue. It later (March 1982) replaced the Whirlwind with the Westland Wessex HC.2 and later still (June 1984) with the Westland Wessex HU.5C. It was the last squadron to use the Westland Wessex.
  • Since January 2003 the squadron has been assigned to British Forces Cyprus at RAF Akrotiri in the search and rescue role using the Bell Griffin HAR2. The helicopters are leased from and maintained by a civilian company. 84 Squadron aircraft are also used for UN duties in maintaining the buffer zone separating Cypriot and Turkish forces. In recognition of this role the aircraft are always unarmed and carry a light blue band around their tail, matching the blue berets of UN peacekeepers.
  • 84 Squadron is the only serving squadron never to have been based in the United Kingdom.

  • Nakajima Ki-84 Hayate
  • The Nakajima Ki-84 Hayate was the result of the Imperial Japanese Army Air Service’s search for an aircraft that was a combination of their own agile Ki-43 Hayabusa and their fast Ki-44 Shoki that could compete with newest allied designs.
  • The Ki-84 Hayate (“Gale”) or the Army Type 4 Fighter which was it’s official IJA designation. Hayate was capable of matching the best allied aircraft in the Pacific theater and with its powerful armament to bring down any allied bomber.
  • It was numerically the most important fighter serving with the Japanese Army Air Force (JAAF) during the last year of the Pacific War, and was probably the best Japanese fighter aircraft to see large-scale operation during this period of the war. The Hayate was fully the equal of even the most advanced Allied fighters which opposed it, and was often their superior in many important respects. It was well armed and armoured, was fast, and was very manoeuvrable. Although it was generally outnumbered by Allied fighters which opposed it, it nevertheless gave a good account of itself in battles over the Philippines, over Okinawa, and over the Japanese home islands.

  • F-84 “Thunderjet”
  • Republic Aviation Corporation, Long Island, New York, built P-84 Thunderjets in the 1940s. The Thunderjets were the last of the subsonic straight-wing fighter-bombers to see operational service. They were the aircraft with which flight-refueling techniques for fighters were developed. The first fifteen P-84 production aircraft were fitted with Allison J35A-15 engines and designated YF-84As.
  • F-84 “Thunderjet” was the USAF’s first post-war fighter, making its initial flight on February 26, 1946. Gaining its greatest renown during the Korean War, it was used primarily for low-level interdiction missions. The F-84 attacked enemy railroads, bridges, supply depots and troop concentrations with bombs, rockets and napalm. Its maximum speed was 620 mph.

  • Republic XF-84H
  • The Republic XF-84H “Thunderscreech” was an experimental turboprop aircraft derived from the F-84F Thunderstreak. Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome teething aerodynamic deficiencies, resulting in the cancellation of the program.

  • Canadair CL-84 “Dynavert”
  • The Canadair CL-84 “Dynavert”, designated by the Canadian Forces as the CX-131, was a V/STOL turbine tiltwing monoplane designed and manufactured by Canadair between 1964 and 1972. Only four of these experimental aircraft were built with three entering flight testing. Two of the CL-84s crashed due to mechanical failures, but no loss of life occurred as a result of these accidents. Despite the fact that the CL-84 was very successful in the experimental and operational trials carried out between 1972 and 1974, no production contracts resulted.

  • M-84
  • The M-84 is a main battle tank from the former Yugoslavia .
  • In the 1970s, the Yugoslav army decided to develop its own battle tanks and produce.

The rights of the licensed acquired in 1979 by the Soviet Union. Codenamed Kapela was in the armor wrought Ðuro Ðakovic in Slavonski Brod (Croatia) started production. The first prototype was completed in 1983, and mass production began 1984.  Until the outbreak of war in Yugoslavia over 500 pieces for the Yugoslav army were produced. The battle tank M-84 presented a significant improvement of the overall T-72 represents in the following years made more combat performance upgrades and modernizations in different versions.

  • Z-84
  • The Z-84 again replaced the previous Star SMGs in service, starting in the mid 1980s. The theory was to acquire a gun in 9 mm Parabellum, to match their pistols (and the NATO countries finally). It was offered on the commercial market in 9 mm Largo, but none seem to have been made.
  • The Spanish Army, Air Force and Marines supposedly mostly got out of issuing SMGs around the time this emerged — much like the rest of the world — due to the prevalence of lightweight, select-fire rifles. Unlike the previous replacement cycles, therefore, the Z-70B is still in widespread service for those who are issued SMGs (see the sailors at the top of the page). The Z84 is employed by some Guardia, Police and Military units. Aside from general use (such as the boarding party sailors below), in a recent Small Arms Review article, Julio Montes says:
  • An interesting weapon in the hands of these naval commandos [the UEBC and UOE] is the locally made Star Z-84… It has proved very efficient and reliable even after being submerged and beat up for longer periods of time. The ever-present MP5 is also found.

  • Mauser Gewehr 71/84
  • On December 2, 1871, the Mauser Infantry Rifle Model 71, was officially adopted by the Prussian government, thus becoming the first bolt-action metallic cartridge rifle to enter German military service.
  • The original design single-shot was updated in 1884, refinements including an 8-round tubular magazine designed by Alfred von Kropatschek, making this Germany’s first repeating rifle. This version was designated the Gewehr 71/84 and was officially adopted by the army of Kaiser Wilhelm I on January 31, 1884.
  • In the film The Last Samurai the Japanese Imperial Army carries German bolt-action Mauser M1871/84 rifles, in spite of the fact they were supposedly being armed by the U.S. The 1884 models were altered in appearance by film makers to resemble the more period accurate 1871 models.

  • Carl Gustav Recoiles Rifle
  • The Carl Gustav (also Carl-Gustaf and M2CG; pronounced “Carl Gustaf”) is the common name for the 84 mm man-portable reusable multi-role recoilless rifle produced by Saab Bofors Dynamics (formerly Bofors Anti-Armour AB) in Sweden.
  • The first prototype of the Carl Gustaf was produced in 1946, and while similar weapons of the era have generally disappeared, the Carl Gustaf remains in widespread use today.
  • British troops refer to it as the Charlie G, while Canadian troops often refer to it as the 84, Carl G or Carlo. In U.S. military service it is known as the M3 Multi-role Anti-armor Anti-tank Weapon System (MAAWS) or Ranger Antitank Weapons System (RAWS), but is often called the Gustav or the Goose or simply the Carl Johnson by U.S. soldiers. In Australia it is irreverently known as Charlie Gusto or Charlie Gutsache (guts ache, slang for stomach pain). In its country of origin it is officially named Grg m/48 (Granatgevär or grenade rifle, model 48).
  • In recent years, the weapon has found new life in a variety of roles. The British Special Air Service, United States Special Forces and United States Army Rangers use M3s in bunker-busting and anti-vehicle roles, while the German Bundeswehr maintains a small number of M2s for battlefield illumination. Many armies continue to use it as a viable anti-armor weapon, especially against 1950s- and 1960s-era tanks and other armored vehicles still in use worldwide.
  • In a well-documented incident during the Falklands War, a Royal Marine attacked an Argentinian corvette (ARA Guerrico) using a Carl Gustav.
  • The Carl Gustav was used against Taliban defensive fortifications by soldiers of Princess Patricia’s Canadian Light Infantry in operations in Afghanistan. They developed a new system for firing at night in which a spotter with a night-scope fires tracer ammunition to mark the target for the Carl Gustav gunner.[citation needed]
  • Carl Gustav launchers were used by Free Libyan Army during the Libyan civil war in 2011; the weapons being used were either captured or provided by defecting members of the Libyan Army.

  • M84 Škorpion vz. 61
  • The Škorpion vz. 61 is a Czechoslovak 7.65 mm submachine gun developed in 1959 by Miroslav Rybár (1924–1970) and produced under the official designation Samopal vzor 61 (“submachine gun model 1961”) by the Ceská zbrojovka arms factory in Uherský Brod.
  • Although it was developed for use with security forces and special forces, the weapon was also accepted into service with the Czechoslovak Army, as a personal sidearm for lower-ranking army staff, vehicle drivers, armored vehicle personnel and special forces. Currently the weapon is in use with the armed forces of several countries as a sidearm.
  • The Škorpion was also license-built in Yugoslavia, designated M84. It features a synthetic pistol grip compared to the original version. A civilian, semi-automatic version was also produced, known as the M84A, also available in .380 ACP (9×17mm Short).

1944 was arguably the most interesting year of World War II. Incidents of note included:


  • The Fosse Ardeatine massacre in Rome when 335 Italians are killed, including 75 Jews and over 200 members of the Italian Resistance from various groups.


  • The real “Great Escape” (as opposed to the famous movie version) when 76 Royal Air Force prisoners escape by tunnel “Harry” from Stalag Luft III. Only three made it back to the UK, and of those recaptured, fifty were executed.


  • Exercise Tiger, or Operation Tiger, was the code name for one in a series of large-scale rehearsals for the D-Day invasion of Normandy, which took place on Slapton Sands or Slapton Beach in Devon.
  • The first practice assault took place on the morning of 27 April. H-hour was set for 7:30 am, and was to be preceded by a live firing exercise to acclimatize the troops to the sights, sounds and even smells of a naval bombardment. During the landing itself, live rounds were to be fired over the heads of the incoming troops by forces on land, for the same reason. This followed an order made by General Dwight D. Eisenhower, the Supreme Allied Commander, who felt that the men must be hardened by exposure to real battle conditions.
  • The British heavy cruiser HMS Hawkins was to shell the beach with live ammunition, from 6:30 to 7:00 am, giving the beachmasters half an hour to inspect the beach and declare it safe.
  • However, several of the landing ships for that morning were delayed, and the officer in charge decided to delay the bombardment until 8:30am. This message was received by HMS Hawkins, but not by a number of the landing craft, with the result that troops were landing on the beach at the same time as the bombardment was taking place. This unfortunate mix-up resulted in a “friendly fire” incident with 946 American servicemen losing their lives.
  • The incident was under the strictest secrecy at the time due to the impending invasion, and was only nominally reported afterward. As a result it has been a largely “forgotten” disaster of WWII.

  • However many people mistakenly believe that the Smith & Wesson (S&W) .44 calibre revolver heavily featured in numerous Hollywood movies, particularly Clint Eastwood’s Dirty Harry is called the .44 Magnum (the most powerful handgun in the world), neither of which are true. The revolver used in those movies is actually the Smith & Wesson Model 29, a six-shot, double-action revolver chambered for the .44 Magnum cartridge. It comes in a variety of models with 3″, 4″, 5″, 6″, 6½”, 8″ and, later, 10″ barrel lengths.
