Podcast Script

podcast_script": “Welcome back to the LL Study Guide review podcast for season one oh nine, match day two. I’m glad you’re here.

We’re going to walk through all six questions from today’s match, talk about the right answers, and add just enough story and context so these ideas actually stick. If you want the full write up, with links and deeper dives, you can always check the study notes on our website at L L Study Guide dot com.

Let’s jump right in with question one.

Question one was: What imperial and U.S. customary unit is equal to 258.9988 hectares?

The correct answer is: square mile.

So, a square mile is the basic big chunk of land in the old imperial and U.S. customary systems. One square mile is the area of a square that’s one mile by one mile on each side. When you convert that to metric, it’s a little over two and a half square kilometers, and more precisely, about two hundred fifty-nine hectares. That matches the number in the question, two hundred fifty-eight point nine nine eight eight.

A hectare, by contrast, is a metric unit. Picture a square that’s one hundred meters on each side. That’s ten thousand square meters, and that’s one hectare. Farmers, foresters, and environmental scientists use hectares all the time.

The fun thing about square miles is that they don’t just live in math problems. In the United States, the public land survey system divides land into “sections,” and a section is exactly one square mile. If you’ve ever flown over the Midwest and seen that big, tidy checkerboard of fields, a lot of that is square-mile sections laid out long ago.

And then there’s the City of London, the historic financial core of London, which is famously nicknamed “the Square Mile.” That’s both a literal nod to the unit, because the district is just over one square mile in area, and a symbolic nickname that gets used in finance news all the time.

If you want to see the exact conversions and some maps that make this clearer, check the study notes on the website.

All right, from units of land to a man who fought across a lot of it: question two.

Question two was: 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 correct answer is: William McKinley.

William McKinley, the twenty-fifth president, was the last U.S. president who actually fought in the Civil War. He enlisted at eighteen in the twenty-third Ohio Volunteer Infantry, fought for the Union, and rose from private all the way up to brevet major.

A “volunteer infantry” regiment like the twenty-third Ohio wasn’t part of the small prewar regular army. It was made up of civilians who signed up after the war broke out. Brevet rank, like McKinley’s brevet major, was basically an honorary promotion given for gallantry or meritorious service. You might still get paid as a lower rank, but you could be addressed and recognized as the higher one.

The twenty-third Ohio is a great pub quiz answer all by itself, because it had not one but two future presidents: Rutherford B. Hayes, who commanded the regiment and later became the nineteenth president, and then young McKinley, who served under him. Imagine telling people in that unit, “Two guys here are going to be president someday.”

McKinley’s Civil War service became a big part of his political image. One favorite story from the Battle of Antietam has him dashing under fire to bring hot coffee and food to troops at the front. Whether or not that’s embellished, his campaign used that story heavily when he ran for president in the eighteen nineties, at a time when many veterans were still voting and Civil War memory was central to politics.

He’s also the final entry in that run of Union veterans in the White House: Ulysses Grant, Rutherford Hayes, James Garfield, Benjamin Harrison, and then McKinley. Together they define a lot of what we call the Gilded Age presidency.

If you like musical theater, McKinley shows up again in Stephen Sondheim’s show “Assassins.” The assassin, Leon Czolgosz, and the Buffalo exposition where McKinley was shot are all dramatized there. It’s a very different way to meet a nineteenth-century president, but a memorable one.

You can dig into the regiment’s history and McKinley’s battlefield stories in the study notes on our site.

Now we pivot from battlefields to abstract math that still ends up winning Nobel Prizes. On to question three.

Question three was: 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 correct answer is: topology.

Topology is often called “rubber sheet geometry.” It’s the branch of math where you care about properties that don’t change if you stretch, twist, or bend an object, as long as you don’t tear it or glue parts together. So a circle and a perfect oval are the same from a topological point of view. But a donut and a sphere are different, because the donut has a hole.

That donut brings us to the classic topology cartoon: a coffee mug with one handle is, topologically, the same as a donut. You can imagine deforming the donut until part of it sticks out like a handle and deepens into a cup shape, all without cutting or attaching anything new. There’s still just one hole. That’s the kind of thinking topology studies.

The word itself comes from Greek: “topos” meaning place, and “logos” meaning study. So, “study of place.” The question contrasts it with topography, which is “topos” plus “graphia,” meaning writing or description. Topography is about mapping mountains and valleys on the actual Earth’s surface. Topology doesn’t care whether your space is a landscape, a rubber band, or some high dimensional abstract object.

What makes this question fun is that the Nobel Prize in Physics in twenty sixteen was awarded for using these purely mathematical ideas in real materials. Thouless, Haldane, and Kosterlitz showed that certain strange phases of matter, like very thin films or systems in extremely low temperatures and strong magnetic fields, have properties you can best understand using topology. For example, some quantities in those systems take on whole-number values that stay locked in place unless something dramatic happens. Those integers are topological in origin.

And once you start looking for it, topology pops up all over culture. The Möbius strip, that single-sided twist of paper, shows up in art, in logos, in Escher prints. Klein bottles, impossible to build perfectly in our three-dimensional world, feature in geeky T-shirts and puzzles. They all come from the same way of thinking about shapes that don’t change under smooth deformations.

If you want a gentle explanation of the Nobel work with nice diagrams, check the show notes; we link to the Nobel committee’s “popular science” summary there.

From abstract shapes, let’s head to the edge of the map, where countries and time zones nearly touch. Question four.

Question four was: 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 correct answer is: Russia and the United States.

The Diomede Islands sit right in the middle of the Bering Strait, between Alaska and Siberia. Little Diomede belongs to the United States, as part of Alaska. Big Diomede belongs to Russia. The distance between them is only about two point four or two point five miles, just a few kilometers.

So while you might have heard that Alaska and Russia are about fifty-five miles apart at their closest points on the mainland, between these two islands that gap shrinks to essentially a long swim. In fact, swimmer Lynne Cox did exactly that in nineteen eighty-seven, crossing from Little Diomede to Big Diomede in near-freezing water as a symbolic Cold War peace gesture.

Another twist here is time. The International Date Line runs between the islands, so even though they’re only a couple of miles apart, they’re almost a full day apart on the calendar. That’s where the nicknames “Yesterday Island” for Little Diomede and “Tomorrow Island” for Big Diomede come from. You can literally see into “tomorrow,” at least in a poetic sense.

Geographically, they sit in the region called Beringia, which is the name we give to the land bridge that once connected Asia and North America when sea levels were lower. Many archaeologists think early humans, along with mammoths and other animals, crossed between continents here.

Because of all that, the Diomede pair shows up a lot in geography trivia and pop science articles. They’re a neat example of how international borders, time zones, and deep history all stack up in one tiny spot.

For maps and satellite images that really show how close those islands are, take a look at the study notes on our site.

Now let’s head from frozen islands to a very different kind of confinement: a fictional maximum security prison on premium cable. Question five.

Question five was: 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 correct answer is: Oz.

Oz is a gritty one-hour prison drama created by Tom Fontana that premiered on HBO in July nineteen ninety-seven. It’s widely recognized as HBO’s first true one-hour dramatic series. Before that, HBO had done original shows like The Hitchhiker, a half-hour horror and mystery anthology, and First and Ten, a half-hour football comedy. Oz is the one that really established the hour-long prestige drama format on the network.

The show is set in a fictional maximum security prison called Oswald State Correctional Facility. Inside it, there’s an experimental unit called Emerald City. Yes, that’s a deliberate Wizard of Oz nod. The prison as a whole is nicknamed “Oz,” and the tagline “It’s no place like home” is a dark twist on Dorothy’s famous “There’s no place like home.” Instead of magical safety, you get violence, gang rivalries, and moral ambiguity.

Oz broke a lot of television rules at the time. It was brutally violent, and because it was on a subscription cable channel, it pushed explicit content and language in ways network shows couldn’t. It also treated characters as genuinely mortal and fallible. Main characters could disappear or die in shocking ways. The show used a lot of serialized storytelling, where actions had long-term consequences.

In retrospect, Oz looks like the opening move in HBO’s prestige TV era. Without Oz, it’s hard to imagine The Sopranos arriving two years later, followed by The Wire, Six Feet Under, and all the others. Many actors moved from Oz to those later shows. Fans of The Wire will recognize faces like J. D. Williams, Seth Gilliam, Lance Reddick, and more popping up in Oz first.

If you want to trace that family tree of actors and see how critics talk about Oz as the “first” HBO drama, you can find those references collected in the show notes.

Finally, we close with a question from the world of fast food and clever utensils. Question six.

Question six was: 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 correct answer is: spork.

A spork is that hybrid utensil that’s mostly a spoon, but with short fork tines at the end, and sometimes even a little cutting edge. You see them all the time in school cafeterias, fast food restaurants, and on airplanes.

Back in eighteen seventy-four, Samuel W. Francis got a U.S. patent for an “improvement in combined knives, forks, and spoons.” His design was more elaborate than a simple plastic spork, but the idea was the same: a single tool that could do the job of multiple pieces of cutlery.

The word “spork” itself is a portmanteau, combining “spoon” and “fork.” It shows up in the early twentieth century, and in nineteen fifty-one, Hyde W. Ballard registered “Spork” as a trademark for a particular kind of stainless steel combination utensil. Then in nineteen seventy, the Van Brode Milling Company registered it again for a plastic spoon-fork-knife product.

At the same time, K F C started handing out plastic sporks with their meals in the nineteen seventies. They were cheap, lightweight, and covered most of what customers needed to eat chicken, mashed potatoes, and coleslaw. That’s a big reason the spork feels so closely associated with fast food culture.

It’s also a great reminder of the difference between patents and trademarks. A patent protects an invention, the way something works mechanically, for a limited time. A trademark protects the name, logo, or symbol used to sell it. So you can have many people making spork-like utensils long after the original patents expire, but specific brands can still own the word “Spork” in certain contexts.

The spork has even turned into a little cultural icon. In Pixar’s movie WALL E, there’s a gag where the robot is sorting old cutlery into forks and spoons, then freezes in confusion when he picks up a spork. He can’t decide which pile it belongs in. There’s also an indie film literally titled “Spork,” about a teenager nicknamed after the utensil, leaning into that in-between, hybrid identity.

If you’d like to see the original eighteen seventy-four patent drawings or read more about the amusing alternative name “foon,” the study notes on our site have you covered.

All right, that’s all six questions from match day two.

To quickly recap: A square mile matches about two hundred fifty-nine hectares. William McKinley was the last Civil War combat veteran to become president. Topology is the abstract “study of place” behind that twenty sixteen Nobel. The Diomede Islands are the closest points between Russia and the United States. Oz kicked off HBO’s era of one-hour prestige dramas. And the humble spork turned a nineteenth-century patent into a fast food staple.
