Mapped: The Literal Translation of Every Country’s Name

 


By 


These days, planes, trains, and automobiles can deliver us to any destination we can name. But how often can we say we know the origins of those names?

Today’s map comes to us courtesy of Credit Card Compare, and it visualizes the literal translations of every country’s name, arranged by continent. Of course, naming conventions are always layered and open to interpretation — especially when they’ve gone through multiple levels of translation — but it’s still an interesting exercise to trace where they are thought to come from.

North America

Starting with the Great White North, Canada’s name is derived from the Indigenous Huron people. Kanata means village, or settlement, in the Iroquoian language. Meanwhile, The United States of America was named in honor of the Italian explorer Amerigo Vespucci. Vespucci is credited with correcting Columbus’ error, in which the latter mistook the New World for the East Indies.

Finally, Mexico comes from the simplified Spanish translation for the Aztec capital, Metztlixihtlico, which is said to mean “place at the center of the moon”. The word is a blend of mētztli for ‘moon’, xictli for ‘navel’ or ‘centre’, and the suffix -co for ‘place’.

South America

Brazil’s name is actually shortened from Terra do Brasil (land of Brazil). The brazilwood tree, or pau-brasil, was valued highly in the early 16th century. It was used to produce red dyes for the European textile industry — hence the “red like an ember” moniker.

Uruguay has a couple of meanings attached to it, the first being “Bird’s Tail” in reference to the uru, a type of quail that lived by the river. Another association is the uruguä, a species of mussel, for which the country is named “River of Shellfish”. It’s interesting to note the relationship to water and rivers, which is reflected in the similarly-themed naming history across the continent.

Venezuela is named for its resemblance to the Italian city of Venice, thus gaining the title of “Little Venice”. Another area also named after European cities? Colombia, which was originally named “New Granada” in a hat tip to the capital of the Spanish province.

Europe

The “Land of the Franks”, France, gets its namesake from the Latin word francia. This dates back even further to the Old German word franka, meaning brave, or fierce. There’s also a political angle to the name: King Louis V famously proclaimed that “France signifies freedom”.

The exact origin for Germany is unknown, possibly because it was composed of various tribes and states before 1871. It’s known as Deutschland (for “of the people”) in German, Alemania in Spanish, Niemcy in Polish, and Saksa in Finnish. Another theory ties it with the Celtic word ‘gair’ for neighbor.

By the Mediterranean, the boot-shaped country of Italy gets its name from the symbol of the Southern Italic Vitali tribe: the bull. The name is connected to the Latin vitulus for ‘calf’ or ‘sons of the bull’. Another interpretation is the phrase diovi-telia, which translates to “land of the light”.


Asia

China’s English name comes from the Qin dynasty, the first unified and multinational state in Chinese history. Although the dynasty only existed between 221-207 BC, it had a profound and lasting influence on the country. A fascinating tidbit is that China’s name in fact borrows from the Persian language, and even Sanskrit.

India’s name comes from Greek, but also the Sanskrit Síndhu, where both refer to the Indus River. Bharat is another official and historically significant name for the Republic of India, and Hindustan is an alternative name for the region, but its use depends on context and language.


Oceania

The Land Down Under of Australia is fairly geographical in its name, drawn from the Latin australis for “southern”. The explorer Matthew Flinders popularized the name as we know it in 1804, and “Australia” replaced “New Holland” as the official continent.

The Māori name for New Zealand is Aotearoa, which is most commonly defined as “the long white cloud” — a reference to early Polynesian navigators discovering the country by relying on cloud formations.


Africa

The name Egypt comes from the Ancient Greek Aiguptos and Latin Ægyptus, and is also derived from hūt-kā-ptah (Temple of the Soul of Ptah). The ancient Egyptian name for the country was km.t (pronounced “kemet”), meaning “black land” likely for the fertile soils of the Nile valley. Today, Egypt’s official name is Jumhūrīyat Miṣr al-ʻArabīyah, or “Arab Republic of Egypt”.

South Africa is aptly named for its geographical location. Interestingly, however, the country has different names in the country’s 11 official languages, including English, Afrikaans, the Venda language, the Tsonga language, and the Nguni and Sotho languages.

What rich histories can be uncovered from your country’s name?

FAVORITE IMAGES OF THE WEEK - 20


UFO GALAXY?
So here's the thing about this galaxy, which is otherwise known as NGC 2683. It's a regular spiral galaxy, about 35 million light-years from Earth. But given our (read: Hubble's) vantage point, we see it from the side, so it has a sort of a flying saucer shape. But that's the only reason we call it the UFO galaxy! If we were elsewhere it'd be a regular spiral galaxy. [via Livescience]

SNAIL MASSAGE
The snail massage, available in Siberian Russia, is believed to help eliminate wrinkles and make skin appear more youthful. We can't speak to that, though this picture did gross out a few of our less slime-tolerant writers.

PINK PANTHER, SORT OF
Couple things wrong with calling this a naturally pink panther: First, it's not a panther/cougar/puma/mountain lion--it's a leopard. Second, it's claimed to be pink, but I'm not so sure about it from this photo. It definitely looks a little blushed, but...what do you guys think? Read more here.

MAPPING WIKIPEDIA
Mapping Wikipedia is a project to map out where (and in what language) Wikipedia's writers are writing from. It's fascinating, actually--why are people writing Arabic articles in New York, Boston, and DC, but hardly at all in Philadelphia? Why are Italians writing so many more English-language articles than Spaniards? Play with it here.

In the quest for dark energy, astronomers have created an unprecedented 3-D map of galaxies in a volume of about 650 cubic billion light years.
Hundreds of astronomers from the Sloan Digital Sky Survey III (SDSS-III) and the Max Planck Institutes for Extraterrestrial Physics (MPE) and for Astrophysics (MPA) contributed to this map. The astronomers found that the map agrees with the current cosmological model (the Lambda Cold Dark Matter model) and confirmed that dark energy is a cosmological constant.

Insights Into Dark Energy

Understanding how dark energy interacts and affects our universe is crucial to unraveling how the universe came to be and how it may end. Dark energy is believed to be what contradicts the force of gravity and is what is accelerating the expansion of the universe. These findings were submitted to the Monthly Notices of the Royal Astronomical Society (MNRAS) as a collection of papers.
“We have spent a decade collecting measurements of 1.2 million galaxies over one quarter of the sky to map out the structure of the universe over a volume of 650 cubic billion light-years,” says Dr. Jeremy Tinker of New York University in a press release.
The Baryon Oscillation Spectroscopic Survey (BOSS) of the SDSS-III carried out the precise measurements found. By studying the tugs between dark energy and dark matter, the scientists were able to determine the Baryonic Acoustic Oscillation (BAO) between the galaxies in the map to measure the expansion rate of the universe.

Frozen Waves

The normal BAO size is found from pressure waves that traveled throughout the universe when it was only 400,000 years old (the universe is currently 13.8 billion years old). The distribution of matter throughout the galaxy represents a frozen image of the life of these waves. All galaxies are therefore separated preferentially by a characteristic distance in what is called the BAO scale.
Using observations from the cosmic microwave background (CMB), the size of the acoustic scale at the universe’s current age can be determined. This is because the light that is emitted corresponds to when the pressure waves became frozen. Seeing how the distribution of galaxies has changed since then can give astronomers clues to how dark energy and dark matter have battled over the expansion rate of the universe. Ariel Sanchez, from MPE, was the astronomer who led the search to find the total amounts of dark energy and dark matter in the universe.
“Measuring the acoustic scale across cosmic history gives a direct ruler with which to measure the universe’s expansion rate,” says Sanchez in the same press release. “ With BOSS, we have traced the BAO’s subtle imprint on the distribution of galaxies spanning a range of time from 2 to 7 billion years ago.”

How Far Away?

These very precise measurements had to be analyzed many times, in particular the distances from Earth to the galaxies in the map. Using a spectrometer, the light from a galaxy appears red-shifted as it is moving away from us. The red-shift in light is how the astronomers were able to correlate the galaxy’s distance from Earth; the farther a galaxy is, the faster it moves and therefore the more it is red-shifted. Dr. Shun Saito from MPA contributed models to the BOSS data analysis.
“However, galaxies also have peculiar motions and the peculiar velocity component along the line-of-sight leads to the so-called redshift space distortion,” says Saito in the same press release. “This makes the galaxy distribution anisotropic because the line-of-sight direction is now special — only along this direction the distance is measured through a redshift, which is contaminated by peculiar velocity. In other words, the characteristic anisotropic pattern allows us to measure the peculiar velocity of galaxies — and because the motion of galaxies is governed by gravity, we can use this measurement to constrain to what level Einstein’s general relativity is correct at cosmological scales. In order to properly interpret the data, we have developed a refined model to describe the galaxy distribution.”
Another possible approach is to use the angular positions of the galaxies in the sky rather than the 3-D physical positions in the universe.
“This method uses only observables,” says Dr. Salvador Salazar, a junior MPE researcher, in the same press release. “We make no prior assumptions about the cosmological model.”
Many approaches have been used to try and analyze the huge BOSS data set. “We now have seven measurements, which are slightly different, but highly correlated,” Sanchez says in a separate press release. “To extract the most information about the cosmological parameters, we had to find not only the best methods and models for data analysis but also the optimal combination of these measurements.”

Upholds Theory

Their strenuous efforts have paid off as the BOSS data show that dark energy is causing the expansion of the universe with an error of only 5 percent in the cosmological constant found. The cosmological constant is called Lambda, as coined by Albert Einstein as a repellant effect in the universe. These findings are still consistent with the relatively young theory of the cosmological model.
The map also reveals that galaxies tend to move to areas with more matter, staying true to the laws of gravity as well as the infall of material following the laws of general relativity. This suggests that the idea of the expansion of the universe is caused by a phenomenon like dark energy that works on large cosmic scales and dismisses the notion that our laws of gravity are breaking down.

OUR 10 FAVORITE SCIENCE IMAGES OF THE WEEK


The Shiny New iPhone 7
Apple unveiled the next generation of the iPhone — the iPhone 7 and iPhone 7 Plus — at its annual September event this week. While aesthetically similar to the 6s and 6s Plus, the upgraded iPhone has several important differences. It’ll have a pressure-sensitive home button, water resistance, a better camera with image stabilization, a faster processor, and much needed expanded storage capacity. Oh, and it won’t have a headphone jack. Read more about it here.

A Flatworm Named After Obama
A new species of blood fluke was found infecting the lungs of turtles in Malaysia. Scientists found clusters of tens to hundreds of fluke eggs in the turtle’s lung alveoli, the tiny sacks where blood receives oxygen and gets rid of carbon dioxide. They dubbed the parasitic flatworm Baracktrema obamai, in honor of the President of the United States (who is the fifth cousin twice removed of one of the discovering scientists).

Lost And Then Found
The European Space Agency’s Philae lander had been missing since its botched touchdown on comet 67P/Churyumov-Gerasimenko in November 2014. But on September 5th, scientists looking at a photo taken by Philae’s mothership, the Rosetta orbiter, unexpectedly found the lander wedged in a crevasse. The discovery of the lander's location means that researchers can finally decode some of the transmissions sent by Philae back to Ground Control in the time between when the Philae lander bounced out of view and before it stopped sending messages altogether.

Making Generators From Fish Scales
Physicists in India have created a battery-free generator out of fish scales. The clear, flexible generator can harvest the energy from small movements such as body motions, sound vibrations, and wind flow, then convert it into electrical power. The collagen in fish scales is a piezoelectric material, meaning that it generates an electric charge when put under mechanical stress. It offers a more environmentally friendly alternative to traditional piezoelectric generators that rely on toxic elements such as lead and bismuth.

An Ecological Success Story
It’s been a good week for whales. NOAA (National Oceanographic and Atmospheric Administration) Fisheries took nine of 14 populations of humpback whales off the endangered species list. It's a place that humpback whales have occupied since the Endangered Species Act was signed in 1973. The Marine Mammal Protection Act still applies to all humpback whale populations, and the whales will continue to be protected from hunting and other activities. New regulations will also limit the distance at which vessels can approach humpback whales in Alaska and Hawaii, where whales are frequently spotted. But federal agencies will no longer be required to consult with the NOAA every time they engage in an activity that might affect non-endangered humpback whale populations.

Gorgeous Topographic Arctic Maps
A new set of 3D topographic maps offer a gorgeous, high-resolution look at Alaska’s rugged terrain. The maps were created from satellite images at a resolution of two meters, making them the most precise maps yet of the Arctic. They are the first maps to be released by the ArcticDEMs project, which aims to "create the first-ever publicly available, high-resolution, satellite-based elevation map of Alaska." The maps will be updated frequently to document how the landscape changes due to erosion, sea level changes, and other forces.

America’s First Offshore Wind Farm
Four completed wind turbines three-and-a-half miles off the coast of Block Island in Rhode Island are part of a pilot project to generate offshore wind energy in the United States. A Department of Energy assessment of the potential for offshore wind energy found that there were over 320,000 square miles of water off our coasts that could be used to generate 4,150 gigawatts of electricity if it was completely utilized. In 2012, the capacity of all energy plants in the entire United States was only 1,100 GW. Read more here.

A Case For A Vaccine Against Flesh-Eating Bacteria
Scientists found that different strains of a group of bacteria that are responsible for flesh-eating disease, toxic shock syndrome, and strep throat all share the same type of proteinon their surface. These are called M proteins, and though there are more than 200 M proteins that we know of, they all have some features in common. This means that researchers can study the shared patterns and how they may stifle our immune response. And eventually, scientists may be able to develop a vaccine based on these common patterns.

e-Drive Retro
A Green Retrofit For Your Classic Car
E-Drive Retro can turn that gas-guzzling vintage vehicle into a clean, green electric machine. The company has developed a plug-in electric drivetrain of its own design that can replace the internal combustion drivetrain of cars built from the 1950s through the 1970s. The company's goal is to create a whole new category of cars: Electric Vehicle Classic Car Conversion.


Google
Drones That’ll Deliver Your Takeout
Project Wing, a subdivision of Google’s parent company Alphabet, will use self-guiding drones to deliver Chipotle food at Virginia Tech this fall. The drones are capable of both flying and hovering on pre-planned routes, avoiding hazards as they go. If all goes according to plan, the drones will hover and slowly lower the food to the customer below. This will test the drone’s ability to keep the order intact and warm while delivering to the customer, pushing the limits for drone delivery because of food’s relatively fragile nature.
