Study Notes

Question 1: Square Miles and Hectares

SCIENCE - What imperial and U.S. customary unit is equal to 258.9988 hectares?

The unit is the square mile. A square mile (mi² or sq mi) is an area unit in both the imperial and U.S. customary systems; 1 square mile equals 2,589,988.110336 m², which is 258.9988110336 hectares (about 2.59 km²).

A hectare (ha) is a metric land‑area unit equal to a square 100 m on a side — 10,000 m² — or about 2.471 acres, widely used for fields, forests, and farms. Because a square mile contains 640 acres, that works out to roughly 259 hectares, matching the 258.9988‑hectare conversion in the question.

Connections

  • In the U.S. Public Land Survey System, a section is one square mile (640 acres); many Midwestern and Western townships are 6×6 miles, divided into 36 sections, so county maps and rural land deeds often grid the landscape in square‑mile blocks.
  • London’s historic financial district, the City of London, is nicknamed the Square Mile because it covers about 1.1 square miles (2.9 km²); finance stories about “the Square Mile” are literally using this unit as a place‑name.
  • Environmental journalism frequently uses hectares: for instance, Merriam‑Webster’s contemporary examples reference hundreds of thousands of hectares of Indonesian forest loss, and agricultural guides routinely convert hectares to acres or square miles when describing land‑use change.
  • Because 1 hectare is 0.01 km² (0.003861 mi²), a handy rule of thumb is that 100 ha ≈ 0.39 sq mi and 260 ha ≈ 1 sq mi; this kind of back‑of‑the‑envelope conversion shows up in agronomy and land‑management references.

Question 2: William McKinley, Civil War Veteran President

AMER HIST - What man was the last of the five U.S. Civil War combat veterans (all Union) to serve as president, having enlisted in June 1861 at age 18 in the 23rd Ohio Volunteer Infantry and ultimately reaching the rank of Brevet Major?

The answer is William McKinley, the 25th president of the United States. He served in the Union Army’s 23rd Ohio Infantry from 1861 to 1865, rising from enlisted private to brevet major, and was the last U.S. president to have fought in the Civil War, following fellow Union veterans Grant, Hayes, Garfield, and Benjamin Harrison.

The 23rd Ohio was a volunteer infantry regiment—raised from civilian volunteers rather than the small prewar Regular Army—that saw hard campaigning in West Virginia, Antietam, and the Shenandoah Valley. A brevet promotion in the 19th‑century U.S. Army was essentially an honorary promotion to a higher rank, usually granted for gallantry or meritorious service, which typically did not carry the full pay, authority, or seniority of the substantive rank, so McKinley’s brevet‑major title recognized his service without giving him a permanent major’s commission.

Connections

  • The 23rd Ohio is famous for having two future presidents in its ranks: commanding officer Rutherford B. Hayes (later the 19th president) and young commissary sergeant McKinley, a favorite anecdote in Civil War unit histories and battlefield‑tour narratives.
  • McKinley’s Civil War record—including his celebrated dash under fire to deliver hot coffee and rations at Antietam—was heavily used in his 1896 “front porch” presidential campaign, appealing to veterans and projecting steadiness during the turmoil of the 1890s economy.
  • The cluster of five postwar Republican presidents with Union combat service—Grant, Hayes, Garfield, Harrison, McKinley—defines the Gilded Age presidency and is often highlighted in overviews of how Civil War memory shaped late‑19th‑century politics.
  • McKinley’s 1901 assassination at the Pan‑American Exposition in Buffalo by anarchist Leon Czolgosz is dramatized in Stephen Sondheim and John Weidman’s musical Assassins, particularly in “The Ballad of Czolgosz” and related scenes—so musical‑theatre fans may first meet him through that portrayal.

Question 3: Topology and the 2016 Nobel Prize

MATH - David Thouless, Duncan Haldane, and Michael Kosterlitz won the 2016 Nobel Prize for their work on phases of matter related to what branch of mathematics concerned with properties that survive continuous deformation (stretching, bending, etc.)? Its name comes from Greek for “study of place”, and it is distinct from the similarly named field meaning “description of place” that deals with the representation of the Earth’s surface features.

The branch of mathematics is topology. Topology studies properties of spaces that remain unchanged under continuous deformations—stretching, bending, twisting, or crumpling, but not tearing or gluing—and the 2016 Nobel Prize in Physics cited Thouless, Haldane, and Kosterlitz for applying these ideas to “topological phase transitions and topological phases of matter”.

The term topology comes from Greek topos (“place”) and logos (“study”), emphasizing that it is, loosely, the “study of place” at a very abstract level. By contrast, topography (from topos and graphia, “writing/description”) refers to the detailed description or mapping of the Earth’s surface—elevations, landforms, and other surface features represented on topographic maps. A classic topological joke is that a coffee mug with one handle and a donut (torus) are “the same” shape, because one can be continuously deformed into the other without cutting or gluing; what matters is the presence of a single hole.

Connections

  • The Nobel committee’s citation for the 2016 Physics Prize explicitly credits the laureates with revealing how topological concepts explain exotic phases of matter such as thin superconducting films and quantum Hall systems, showing how a once‑esoteric mathematical field now guides real materials science.
  • Visual icons of topology—Möbius strips, coffee‑cup/donut cartoons, and Klein bottles—appear widely in art, logos, and stamp designs; the Möbius strip, for instance, features in artworks by M. C. Escher and in logos for institutions like Brazil’s IMPA and various recycling symbols.
  • Topology has become central to chemistry as well: “chemical topology” and molecular knot theory analyze how knots, links, and other entanglements in molecules affect their properties, with applications to molecular machines, supramolecular chemistry, and topological polymers.
  • In drug discovery, topological indices derived from molecular graphs are used in quantitative structure–activity relationships (QSARs), correlating structural features with biological activity and helping screen candidate molecules computationally.

Question 4: Diomede Islands and U.S.–Russia Geography

GEOGRAPHY - The Diomede Islands are shared by two countries, with 2.4 miles separating Big Diomede to the west (or perhaps technically, far far east) from Little Diomede. These islands serve as the closest points between what two countries?

The islands mark the closest points between Russia and the United States. Big Diomede (Ratmanov Island) belongs to Russia, Little Diomede to the U.S. state of Alaska, and the two rocky islands sit in the middle of the Bering Strait only about 2.4–2.5 miles (around 3–4 km) apart.

The Diomede Islands lie between the Chukchi Peninsula of far‑eastern Russia and Alaska’s Seward Peninsula, within the narrow Bering Strait that links the Pacific and Arctic Oceans. Little Diomede is U.S. territory with a small Inupiat community; Big Diomede is Russian and uninhabited by civilians. The International Date Line passes between them, creating a roughly 21‑hour time difference despite the short distance, which is why they’re sometimes nicknamed “Yesterday Island” (Little Diomede) and “Tomorrow Island” (Big Diomede).

Connections

  • The National Park Service points out that while mainland Alaska and Russia are about 55 miles apart, at the Diomede pair the water gap shrinks to only about 2.5 miles—close enough that winter sea ice can form a temporary bridge between the countries.
  • Long‑distance swimmer Lynne Cox famously swam from Little Diomede to Big Diomede in 1987, covering roughly 2.2 miles in near‑freezing water as a symbolic Cold War–era gesture of goodwill between the U.S. and Soviet Union.
  • The islands sit within the broader region of Beringia, the now‑submerged land bridge that once connected Siberia and Alaska; many archeologists think early humans, as well as animals like mammoths and bison, crossed this corridor between Asia and the Americas when sea levels were lower.
  • Trivia columns, geography blogs, and news quizzes often highlight the Diomede pair as an example of how the U.S. and Russia are only a couple of miles and nearly a full day apart, making them a recurring “fun fact” about international borders and time zones.

Question 5: Oz and the Birth of HBO Drama

TELEVISION - While shows like The Hitchhiker and 1st & Ten existed previously, what series is widely considered HBO’s first true dramatic television series, debuting in July 1997 with the tagline “It’s no place like home”?

The series is Oz, a gritty prison drama created by Tom Fontana. Oz premiered on HBO on July 12, 1997, as the network’s first one‑hour dramatic television series, and promotional materials riffed on The Wizard of Oz with the tagline “It’s no place like home”—a dark inversion of the film’s “There’s no place like home”.

Connections

  • Media historians often credit Oz as HBO’s first full‑blown prestige drama, paving the way for later landmark series like The Sopranos, The Wire, and Six Feet Under by embracing serialized storytelling, morally ambiguous characters, and cable‑only levels of violence, sex, and language.
  • The title, Emerald City cell block, and tagline consciously echo The Wizard of Oz: the prison is nicknamed “Oz”, its experimental unit is “Emerald City”, and the line “It’s no place like home” twists Dorothy’s comforting catchphrase into something ominous about incarceration.
  • Oz became a talent pipeline for HBO: many actors who later anchored The Wire (including J. D. Williams, Domenick Lombardozzi, Seth Gilliam, and Lance Reddick) previously appeared on Oz, so attentive viewers can spot a mini–Wire reunion in this earlier show.
  • Earlier HBO series like The Hitchhiker (1980s horror/mystery anthology) and 1st & Ten (a 30‑minute football sitcom) established HBO’s adult tone but were half‑hour formats; Oz was the first hour‑long original drama, and commentators still point to it as the show that broke many of television’s old rules, from killing off apparent leads to unflinching depictions of prison brutality.

Question 6: The Spork – Hybrid Utensil

FOOD/DRINK - Dr. Samuel W. Francis of Rhode Island received U.S. patent 147,119 on February 3, 1874, for what hybrid, whose common name was trademarked by Hyde W. Ballard in 1951 and the Van Brode Milling Company in 1970, and which was popularized in large part by KFC beginning in the 1970s?

The hybrid utensil is the spork, a combination of spoon and fork (often with a cutting edge). In 1874, Samuel W. Francis of Newport, Rhode Island, received U.S. patent 147,119 for an “Improvement in combined knives, forks, and spoons”—a single implement whose spoon bowl carried fork tines and a knife edge, closely resembling a modern spork. The word spork (a portmanteau of “spoon” and “fork”) appears in early‑20th‑century dictionaries and was registered as a U.S. trademark for a stainless‑steel spoon–fork by Hyde W. Ballard in 1951, then for a plastic spoon–fork–knife by the Van Brode Milling Company in 1970. A modern KFC press release even notes that the chain “helped popularize” sporks in its restaurants in the early 1970s, cementing the utensil in fast‑food culture.

In this context, a patent is a government‑granted exclusive right that allows an inventor to prevent others from making, using, selling, or importing the patented invention for a limited period (typically about 20 years), in exchange for publishing the technical details. A trademark is any word, name, symbol, or design used in commerce to identify and distinguish the goods or services of one producer from those of others—so registering “Spork” protected it as a brand name for particular combination utensils, even though similar designs could still be made under other names. A spork itself is a hybrid eating utensil whose bowl is spoon‑like but features fork‑like tines, often made of lightweight plastic for disposable use.

Connections

  • The spork’s design has made it ubiquitous in institutional settings—fast‑food chains, school cafeterias, prisons, and airlines—because it can handle liquids and solids while remaining cheap and, in plastic form, harder to weaponize than metal cutlery.
  • Pixar’s film WALL‑E turns the spork’s in‑between status into a joke: the robot hero, who carefully sorts human artifacts, finds a plastic spork and can’t decide whether to file it with forks or spoons, reflecting the utensil’s ambiguous identity in a way many viewers remember vividly.
  • There’s even a 2011 indie film titled Spork, about an outsider teen nicknamed after the utensil, underscoring how the word has become a cultural metaphor for hybridity and not fitting neatly into existing categories.
  • Historians of kitchen patents sometimes argue that the name spork underplays earlier designs; one retrospective playfully suggests the modern utensil ought to be called a “foon” (fork + spoon) in honor of another 19th‑century patent that used the term “forked spoon”, illustrating how naming and branding can shape which inventions we remember.
