# Why Experts Can't Agree on the Lengths of the World's Coastlines

Measuring the distance between two places on a map is pretty straightforward. But if you want to calculate how long a shoreline is, things can get complicated. Just search "U.S. coastline length" and you'll find that results can vary by tens of thousands of miles.

How can cartographers come up with numbers that differ so wildly if they're all measuring the same thing? The answer, according to the video below from RealLifeLore, lies in a phenomenon called the Coastline Paradox.

Measuring the East Coast of the U.S. isn't the same as calculating the miles separating the tip of Florida from the tip of Maine. A coast doesn't follow a straight line. It's made up of divots and curves that start to multiply the closer you zoom in on the map. Accounting for every single detail of the coast is impossible. One, because the shore is always changing shape, and two, because these intricacies go all the way down to the molecular level.

That means cartographers have to pick a unit of measurement with which to estimate the length of the coast. If one team measures in miles and another measures in units of 100 miles, their results will look very different. Smaller measurements produce longer and, technically, more accurate numbers. But at some point, if you keep drilling down to smaller and smaller units, the length of a coastline appears to approach infinity—which doesn't seem entirely right, either. So every measurement of a coastline you see is really just a rough estimate.

The Coastline Paradox isn't the only complication that makes cartography an imperfect science. Even Mount Everest's title as the world's tallest mountain isn't totally uncontested.

# 11 Weird Place Names From Around the World

The sign on the train station platform helps you pronounce this 58-letter-long Welsh town name.

Shakespeare wasn’t wrong when he said that a rose by any other name would smell as sweet. But if these places had any other names, they probably wouldn’t have made this list (or international headlines, in a couple of cases). Read on to discover the fascinating details behind Tasmania’s Eggs and Bacon Bay, French Polynesia’s Disappointment Islands, and other strangely named locales from all corners of the globe.

## 1. Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch, Wales

At 58 characters, this tiny Welsh village on the isle of Anglesey has the longest place name in Europe. Translated to English, it’s a phrase that describes the town’s location: Saint Mary's Church in the hollow of the white hazel near a rapid whirlpool and the Church of St. Tysilio of the red cave. According to Atlas Obscura, the town has existed in some form for thousands of years, but in 1880 a publicity-oriented tailor changed its name from Llanfairpwll to its current moniker in an attempt to attract tourists. Luckily for us, Llanfairpwll is still an acceptable nickname, as is Llanfair PG. Listen to weather reporter Liam Dutton pronounce it like a pro here.

## 2. Batman, Turkey

Both a Turkish province and its capital city are named Batman for the nearby Batman River. Batman itself could have come from the ancient unit of measurement (equal to 16.96 pounds), or it could be a shortening of the name of the nearby Bati Raman mountains. Either way, the city became the source of scandal in 2008 when its then-mayor, Huseyin Kalkan, threatened to sue Warner Bros. and director Christopher Nolan over their use of the term in the Dark Knight trilogy. (No lawsuit was ever actually filed.) There are also plenty of people who want to reinforce the connection between the place name and superhero—over 26,000 have signed a petition to change the province’s borders to look like the bat symbol.

## 3. Eggs and Bacon Bay, Tasmania

Tasmania’s Eggs and Bacon Bay is named after a regional wildflower commonly known as eggs and bacon, whose petals are a mixture of the sunny yellow of egg yolks and the deep red of bacon. The bay made national news in 2016 when PETA petitioned unsuccessfully to change its name to a more animal-friendly “Apple and Cherry Bay.” It doesn’t look like the idea ever made it to a vote at the local council, and officials didn’t seem keen on it. Huon Valley deputy mayor Ian Paul told The Guardian that the idea was “ludicrous,” adding “I feel pretty strongly about it. This is our heritage, it is our history.”

## 4. Wonowon, British Columbia

It’s not a coincidence that this Canadian town, pronounced “one-oh-one,” is located on Alaska Highway’s Mile 101, where the U.S. Army operated a 24-hour checkpoint during World War II. The town was originally named Blueberry after the nearby Blueberry River, but was eventually changed to Wonowon to prevent people from confusing it for another Blueberry in the southeastern Kootenay region. It’s not clear when the name officially changed to Wonowon, but according to a mention in a 1956 issue of the Northern Sentinel, the Post Office recognized it as Wonowon, while the residents still called it Blueberry. Why Blueberry in the first place, you ask? Possibly because British Columbia produces 96 percent of Canada’s cultivated blueberries.

## 5. Spa, Belgium

Spa, Belgium, sounds relaxing, and for good reason. The word spa comes from this eastern Belgian town, whose curative mineral springs have been visited since the 16th century and were even mentioned by Pliny the Elder. Spa itself could be derived from espa, the Walloon word for "spring" or “fountain,” or the Latin word spagere, meaning “to scatter, sprinkle, moisten.” Or it could be an acronym for the Latin phrase sanitas per aquas, which fittingly means “health through water.”

## 6. Westward Ho!, England

In 1855, Charles Kingsley published a book called Westward Ho!, in which a young man leaves his home in Bideford, England, to pursue a seafaring life of adventure under the tutelage of famed explorer Sir Francis Drake. The book became a bestseller, and some enterprising folks formed the Northam Burrows Hotel and Villa Building Company in 1863 with the intention of capitalizing on the attention. They started by building the Westward Ho! Hotel, and continued to develop the area by constructing terraces, lodges, bath houses, stables, and a golf club. As development progressed, the village that sprung up around the hotel became known as Westward Ho! also.

## 7. The Office Girls, Antarctica

The Office Girls are two glacial islands, also called nunataks, about seven miles away from Welcome Mountain near the Southern Ocean coast of Antarctica. There are so many tiny pieces of land to map in Antarctica that the U.S. has an Advisory Committee on Antarctic Names to name them all—and in 1970 they chose “The Office Girls” as a tribute to all of the personnel who assisted with the administrative side of the missions from home in the continental U.S.

## 8. Punkeydoodles Corners, Ontario

The origin of the name of this tiny hamlet has been debated for decades. Some people say it’s the product of a German tavern owner’s slurred rendition of “Yankee Doodle Dandy,” while others say Punkeydoodle was an insult thrown at resident pumpkin-grower John Burbrigg by a vexed neighbor, and from then on his plot of land was called “Punkeydoodle’s Corners.” The charming Canadian town was once home to a somewhat charming Canadian crime: Mischief-makers often stole the town’s sign, until Canada Day in 1982, when community members replaced it with a concrete monument that weighs almost a ton.

## 9. Malpelo Island, Colombia

The Spanish words mal pelo translate to “bad hair” in English, implying that this island is in some way a nightmare for bouffants, beehives, and blowouts. It’s more likely the result of a metaphorical game of telephone that spanned half the globe and several centuries. It could be derived from the Latin malveolus, meaning “inhospitable” or “spiteful,” which might’ve become malbolo and later mal pelo [PDF]. It’s also on a world map from 1550 as ye mallabry, which probably means malabrigo, a word for “shelterless” that Spanish cartographers used to mark some islands and bays. Malabrigo sort of sounds like mal pelo, at least if you’re shouting it to someone on the opposite side of the island.

## 10. Hotazel, South Africa

Welcome to Hotazel, where it’s hot as hell—or at least it was on the day in 1915 when a group of land surveyors assessed a farm in South Africa and named the whole place “Hot As Hell,” now spelled “Hotazel.” The climate is actually pretty reasonable, with summer temperatures sometimes reaching the 90s (in Fahrenheit) and winter temperatures sometimes dipping into the 30s.

## 11. Disappointment Islands, French Polynesia

In 1765, Lord Byron’s grandfather John Byron was sailing around the tip of South America when he chanced upon a tiny island in the distance. To him and his scurvy-ridden crew, it looked like paradise, but he soon realized the high surf and coral reefs prevented safe anchorage. That, in addition to the spear-wielding natives stationed along the shore, dashed their hopes so severely that Byron named the island (and its nearby sister landmass) the Islands of Disappointment. This may have shielded the islands from centuries of follow-up explorers, but it also literally gives them a bad name. In reality, says BBC Travel’s Andrew Evans, they’re "timeless."

# 6 Weird Things Embedded in City Streets

Most of us spend our days walking around with our eyes pointed straight ahead or looking around, seeing the rest of the world mostly at eye-level. But there are advantages to looking down, and not just because it helps you avoid stepping on other people’s feet. Strange, wondrous, and occasionally terrible things have been found stuck to the surface of city streets—just take a look at the examples below.

## 1. Toynbee Tiles

If you have a revolutionary idea to share with the masses, you could write an op-ed in a major paper, talk to a local member of congress, start an activist organization, or pay for a PR campaign. Or, you could carve the message into a square of gummy linoleum and stick it in the street. Whatever floats your boat!

The linoleum method is the one employed by the mysterious creator of the Toynbee Tiles—lettered rectangular plaques that have appeared in dozens of major U.S. cities since the 1980s, as well as in several South American locations. Most of the tiles contain some version of the following message:

TOYNBEE IDEA
IN KUBRICK'S 2001
ON PLANET JUPITER

Tile-followers, and there are a few, generally interpret Toynbee as a reference to 20th century British historian Arnold J. Toynbee, although some think it could refer to the Ray Bradbury short story "The Toynbee Convector." The 2001 is, of course, a reference to Stanley Kubrick's 2001: A Space Odyssey, which depicts a voyage to Jupiter.

No one knows who's behind the tiles, and it may not be a single individual. For years, many tile enthusiasts believed they were the work of James Morasco, a Philadelphia carpenter who communicated with the Philadelphia Inquirer in the early 1980s about the idea of resurrecting the dead on the planet Jupiter. But the tiles have continued to appear long after Morasco's death in 2003, and his widow claims he never had anything to do with them.

The story gets much, much weirder. David Mamet claims the idea for the tiles came from one of his plays; many of the tiles contain screeds against the mafia, media, and the Jews; Larry King is somehow involved. For those who are intrigued, the excellent 2011 documentary Resurrect Dead delves deeper into the mystery.

## 2. The Paris Central Guillotine

It’s been called “the most awful spot in Paris.” These five rectangular indents near the Pére-Lachaise Cemetery in Paris look ordinary enough, but they have a grisly tale to tell. They’re actually slabs that once formed the foundation for the Paris guillotine, which sliced off 69 heads—in public—between 1851 and 1899. (France continued sending people to the guillotine until 1977, but not here.) The guillotine stood at the entrance to the now-demolished Prison de la Roquette, and shut down when the prison itself ended its dark days.

## 3. The Hess Triangle

It may be the ultimate New York-style "screw you, buddy," at least as far as the city's streets are concerned. Where 7th Avenue and Christopher Street cross in Manhattan's West Village, there's a mosaic triangle that takes up about 500 square inches. Its black letters spell out an oddly aggressive message: "Property of the Hess Estate which has never been dedicated for public purposes."

The message, and the triangle, are a remnant of a very minor early 20th century property battle, in which New York City used eminent domain to seize a nearby apartment building when expanding the IRT subway in the late 1910s. The apartment building was owned by Philadelphia landlord David Hess, whose family later noticed that the city’s seizing had left them this one tiny triangle. City authorities asked the family to donate the triangle, but they refused, installing this defiant mosaic instead, in 1922. It’s a little outdated, however: in 1938, the family finally gave up and sold the plot to the owners of Village Cigars for \$1000, or \$2 per square inch.

## 4. Jewish Tombstones

During World War II and for decades afterwards, Jewish tombstones in Poland were treated as construction material, plundered from cemeteries to pave streets, courtyards, and passageways, and used to repair walls and curbs. In 2014, the city of Warsaw agreed to return 1000 Jewish tombstones, known as matzevot, that had been used to build a pergola and stairs inside a city park.

Polish photographer Łukasz Baksik spent several years documenting the tombstones’ appropriation as paving material and masonry, with the results published in a book called Matzevot for Everyday Use. Meanwhile, a nonprofit called From the Depths runs the Matzeva Project, which aims to find and restore some of the millions of gravestones still hidden in Poland, as well as the often-forgotten Jewish cemeteries from which the stones were stolen.

## 5. Potholes Crying out for Help

Potholes are the mosquito of urban infrastructure problems: minor but persistently irritating. Over the past few years, several people have been trying new approaches to getting them repaired. In Panama City, the TV show Telemetro Reporta launched a project in 2015 installing motion-sensitive detectors in the city’s potholes. When a car ran over the sensor, the device automatically sent a tweet to the Ministry of Public Works. In Chicago, artist Jim Bachor took a more delicious approach, creating mosaics of popsicles and other items inside potholes both in Chicago and Jyväskylä, Finland. The crudest—but potentially most effective—technique comes from Manchester, where a man who identified himself to the BBC only as “Wanksy” drew penis shapes around potholes. “They [potholes] don't get filled. They'll be there for months,” Wanksy said. “Suddenly you draw something amusing around it, everyone sees it and it either gets reported or fixed." The local city council spokesperson called the drawings “incredibly insulting.”

## 6. Tourist-friendly QR codes

It’s not as weird as the other entries on the list, but possibly more useful. Rio is known for its stunning beaches, spectacular Carnival, and the black-and-white sidewalk mosaics around the city known as Portuguese pavement. In 2013, the city began installing QR codes using the same black-and-white stone used to create decorative images of fish, waves, and vegetation. The city installed about 30 of the codes at beaches, scenic hotspots and historic sites, and tourists can use the codes alongside a smartphone app to get background information in Portuguese, Spanish, and English.

This list first appeared in 2016 and was republished in 2019.
