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.

The Number 25

25

.

In religion

  • In the Bible the number twenty-five is of cardinal importance in Ezekiel’s Temple Vision (Ezekiel 40-48).
  • Twenty-five is also seen near God’s throne in heaven. God’s throne, plus the thrones of the twenty-four elders, makes for 25 total. (Revelation 4:1-4)

In mathematics

  • 25 is a square number, being 5² = 5 × 5.
  • 25 is the smallest square that is also a sum of two squares: 25 = 3² + 4². Hence it often appears in demonstrations of the Pythagorean theorem.

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.

  • USS Bainbridge
  • The nuclear powered USS Bainbridge (DLGN-25/CGN-25) was initially classed as a guided missile destroyer leader in the United States Navy, and later re-designated as a guided missile cruiser in 1975.
  • In 1966–67, 1969, 1970, 1971 and 1972–73, USS Bainbridge was involved Vietnam War combat operations, as well as voyages to Australia, the Indian Ocean and Arabian Sea.
  • In 1982 she won the Marjorie Sterrett Battleship Fund Award.
  • After receiving her final nuclear refueling overhaul in 1983–85, Bainbridge operations included counter-drug smuggling patrols in the Caribbean, several deployments to northern European waters and four Mediterranean cruises including combat operations off Libya.
  • During 1994 she was deployed to support UN resolutions that became part of Operation Sharp Guard, enforcing sanctions against the Former Republic of Yugoslavia and Bosnia.
  • Finally deactivated in October 1995, Bainbridge was decommissioned in September 1996 and towed to Bremerton, Washington in mid-1997 where she was put in dry dock to begin “recycling,” the process by which nuclear-powered warships are scrapped.

  • USS Somerset (LPD-25)
  • The USS Somerset (LPD-25), a San Antonio-class amphibious transport dock, is the fifth ship of the United States Navy of that name; in this case in honor of Somerset County, Pennsylvania.
  • The name honors the passengers of United Airlines Flight 93 whose actions prevented terrorist hijackers from reaching their intended target, forcing the airplane to crash in Stonycreek Township in Somerset County, PA, on September 11, 2001. In the words of Secretary of the Navy Gordon R. England, “The courage and heroism of the people aboard the flight will never be forgotten and USS Somerset will leave a legacy that will never be forgotten by those wishing to do harm to this country.”
  • Some 22 tons of steel from a crane that stood near Flight 93’s crash site have been used to construct Somerset’s stemhold.
  • She was launched on 14 April 2012, and was christened three months later, on 28 July.

  • 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.
  • The M25 “Three Shot Bazooka” was an experimental tripod mounted rocket launcher with overhead magazine circa 1955.

  • Remington R-25
  • The Remington R-25 is a hi-tech hunting rifle that uses the direct-impingement gas system, where gas is ported down a tube into the action and the bolt carrier is cycled via the gas blowing the carrier off the tube.
  • The upper and lower receivers are made from aluminum forgings, and the handguard is turned aluminum, all impervious to the weather; climate changes will have no effect on accuracy or bedding.
  • Additionally, the R-25 has a Mossy Oak Treestand coating, so if you aren’t careful in the woods, you may spend some time hunting for the rifle you set down while doing something else.
  • The magazine holds four rounds, a prudent choice since the purpose of the R-25 is hunting.

Time for another significant number factoid Friday.

Today the number is one hundred and fifty, 150.

These are just some of the things that are associated with that number.

Enjoy.

One Hundred And Fifty  150

.

In religion

  • There are 150 Psalms in the Bible, the authorship of which is usually ascribed to King David, although scholars now believe that they are the work of several authors.
  • Psalm comes from the Greek psalmos, a song sung to a harp. Some ultra-orthodox Protestant sects (like the Free Church of Scotland) forbid the singing of any hymns that aren’t psalms.
  • The last Psalm in the Bible, Psalm 150, is perhaps the one most often set to music.

  • The number of sons of Ulam, who were combat archers, in the Census of the men of Israel upon return from exile (I Chronicles 8:40)

In mathematics

  • 150 is the sum of eight consecutive primes (7 + 11 + 13 + 17 + 19 + 23 + 29 + 31).
  • Given 150, the Mertens function returns 0.
  • In 150BC the Greek Stoic philosopher and polymath, Crates of Mallos, while laid up in Rome, staved off boredom by constructing the world’s first 3D globe. It showed four symmetrical land masses, separated by water and a central ocean.
  • The Professor’s cube is a 5 x 5 x 5 version of Rubik’s cube (which is 3 x 3 x 3). It has 150 coloured squares.

In science

  • Steven Austad, a health researcher at the University of Texas, believes that children who are alive today could easily live to 150.
  • Based purely on body size, when compared with other mammals, humans shouldn’t live more than 30-40 years. But our large brain enables us to live in complex social groups that give us protection. The evidence is there in other species: solitary wasps have a lifespan of two weeks but social wasps live for three years.
  • In much the same way lions, which are sociable creatures, live longer than tigers, which are solitary. Austad is so sure that someone alive today will still be here in the year 2150 that he has placed a bet on it with a friend. Presumably he also believes that he will be around to collect.
  • The only animal currently capable of living for 150 years is the giant tortoise.

.

  • Dunbar’s number
  • Dunbar’s number is a suggested cognitive limit to the number of people with whom one can maintain stable social relationships. These are relationships in which an individual knows who each person is, and how each person relates to every other person.
  • Proponents assert that numbers larger than this generally require more restrictive rules, laws, and enforced norms to maintain a stable, cohesive group. It has been proposed to lie between 100 and 230, with a commonly used value of 150.
  • Dunbar’s number states the number of people one knows and keeps social contact with, and it does not include the number of people known personally with a ceased social relationship, nor people just generally known with a lack of persistent social relationship, a number which might be much higher and likely depends on long-term memory size.
  • Dunbar’s number was first proposed by British anthropologist Robin Dunbar, who theorized that “this limit is a direct function of relative neocortex size, and that this in turn limits group size … the limit imposed by neocortical processing capacity is simply on the number of individuals with whom a stable inter-personal relationship can be maintained.” On the periphery, the number also includes past colleagues such as high school friends with whom a person would want to reacquaint themself if they met again.

  • A-150 – The Batleship that never was.
  • Design A-150, also known as the Super Yamato class,[A 1] was an Imperial Japanese plan for a class of battleships. Begun in 1938–39, the design was mostly complete by 1941.

  • The Puckle gun
  • The Puckle gun (also known as the Defence gun) was invented in 1718 by James Puckle (1667–1724) a British inventor, lawyer and writer.
  • It is a tripod-mounted, single-barreled flintlock weapon fitted with a multi-shot revolving cylinder. It was intended for shipboard use to prevent boarding.
  • The barrel was 3 feet (0.91 m) long with a bore of 1.25 inches (32 mm). It had a pre-loaded cylinder which held 11 charges and could fire 63 shots in seven minutes—this at a time when the standard soldier’s musket could at best be loaded and fired three times per minute.
  • Puckle demonstrated two versions of the basic design: one, intended for use against Christian enemies, fired conventional round bullets, while the second variant, designed to be used against the Muslim Turks, fired square bullets. The square bullets were considered to be more damaging. They would, according to the patent, convince the Turks of the “benefits of Christian civilization.” The square bullets, however, were discontinued due to their unpredictable flight pattern.
  • The Puckle Gun drew few investors and never achieved mass production or sales to the British armed forces, mostly because British gunsmiths at the time could not easily make the weapon’s many complicated components.
  • One newspaper of the period sarcastically observed, following the business venture’s failure, that the gun has “only wounded those who hold shares therein”.
