Why Macedonia Is Getting a New Name

For the first time since becoming an independent nation in 1991, the Republic of Macedonia is rebranding itself. As CNN reports, the Balkan nation will soon be called the Republic of Northern Macedonia, a name change that will hopefully help to heal the country's tense relationship with Greece.

Macedonia adopted its former title after gaining independence from Yugoslavia 27 years ago, and the name immediately caused conflict. Its neighbor to the south, Greece has a region of its own called Macedonia. Greece claimed that Macedonia's name suggested a sense of entitlement to territory that belonged to them and took it as an insult.

Even decades later, the bad blood stirred by the decision remained. Greece's issue with the name has even prevented Macedonia from joining the European Union and NATO. The new title, which was agreed upon by Macedonian prime minister Zoran Zaev and Greek prime minister Alexis Tsipras on June 11, is meant to be a step towards better relations between the two countries.

"Our bid in the compromise is a defined and precise name, the name that is honorable and geographically precise—Republic of Northern Macedonia," Prime Minister Zaev said at a press conference, as reported by Reuters. Macedonia will hold a popular vote to officially change the name in a referendum later this year.

A country changing its name isn't uncommon, but reasons for the revision vary. In April 2018, the country formerly known Swaziland announced it would be called eSwatini, the name it went by prior to British colonization.

Are You Smart Enough to Pass Thomas Edison's Impossible Employment Test?

If you thought Elon Musk's favorite question to ask job applicants was tough, you should see the employment test devised by Thomas Edison. When he wasn't busy inventing the light bulb or phonograph, or feuding with Nikola Tesla, Edison was apparently devising a trivia test of nearly impossible proportions.

As Smithsonian reports, the 146-question quiz was designed to weed out the candidates who would be ill-suited to work at his plant, which was a desirable place to get a job in 1921. College degrees didn't impress him much—"Men who have gone to college I find to be amazingly ignorant," he once remarked—so he needed to find a more effective method of determining prospective employees' knowledge.

The test may have been too effective, though. Of the 718 applicants who took the test, only 57 achieved a passing score of 70 percent, and only 32 scored Edison's desired result of 90 percent or higher. This was certainly frustrating to applicants who considered themselves to be pretty well-educated. An unsuccessful applicant named Charles Hansen, who shared all of the questions he remembered with The New York Times in 1921, called the test a "silly examination." Another applicant said it was "not a Tom Edison but a Tom Foolery test" [PDF].

After the test questions became public knowledge, reporters went out and started polling people to see how well they'd do on Edison's test. Albert Einstein reportedly failed (he didn't know the speed of sound offhand), as did Edison's youngest son, who was a student at MIT at the time.

If you want to challenge yourself, check out a few of the questions below, then scroll down to see the answers that appeared in The New York Times. (Note: The answers given were the correct answers in 1921, but some may have changed since then. Some questions and answers have been edited lightly for clarity.)

1. What city in the United States is noted for making laundry machines?

2. In what country other than Australia are kangaroos found?

3. What region do we get prunes from?

4. Name a large inland body of water that has no outlet.

5. What state is the largest? The next?

6. What is the name of a famous violin maker?

7. What ingredients are in the best white paint?

8. What causes the tides?

9. To what is the change of seasons due?

10. Who discovered the South Pole?

11. How fast does light travel per foot per second?

12. Of what kind of wood are axe handles made?

13. What cereal is used all over the world?

14. Name three powerful poisons.

15. Why is a Fahrenheit thermometer called Fahrenheit?

1. Chicago

2. New Guinea

3. Prunes are grown in the Santa Clara Valley and elsewhere.

4. The Great Salt Lake, for example

5. Texas, then California (Note: Today it's Alaska, then Texas)

6. Stradivarius

7. Linseed oil, with a small percentage of turpentine and liquid dryer, together with a mixture of white lead and zinc oxide

8. The gravitational pull of the moon exerted powerfully on the ocean because of its fluidity, and weakly on the Earth because of its comparative rigidity.

9. To the inclination of the Earth to the plane of the ecliptic. In the Earth's revolution around the Sun, this causes the Sun's rays to be received at varying inclinations, with consequent variations of temperature.

10. Roald Amundsen, and then Robert Falcon Scott

11. Approximately 186,700 miles a second in a vacuum and slightly less through atmosphere.

12. Ash is generally used in the East and hickory in the West.

13. No cereal is used in all parts of the world. Wheat is used most extensively, with rice and corn next.

14. Cyanide of potassium, strychnine, and arsenic are all acceptable answers.

15. It is named after Gabriel Daniel Fahrenheit, the German physicist who invented it.

Why is North Always Up on Maps?

Geophysicists recently updated the World Magnetic Model—navigational data used for everything from cell phones to satellites—and found that magnetic north, a spot once located in Arctic Canada, is moving quickly toward Siberia. But even this discovery doesn't quite explain why maps always feature north at the top.

There’s nothing inherently upward about north. Some early Egyptian maps put south on top, while in medieval Europe, Christian cartographers tended to give that distinction to east, since you had to turn that way to face Jerusalem. Others placed east on top because of the rising Sun (that’s why we orient ourselves). And early American settlers sometimes used maps with west on top, because that was the direction they were often heading.

If anyone deserves the blame for today’s northward bias, it’s Claudius Ptolemy. In the 2nd century, he wrote the influential Geographia, which featured a “global” map with north on top. No one’s positive why he positioned it that way, but it may be that the Library of Alexandria—where he did his research—simply didn’t have much information on the Southern Hemisphere. During the Renaissance, Ptolemy’s work was revived. By then, the phenomenon of magnetic north had been discovered, making his layout even more appealing to mapmakers.

The magnetic north pole, however, was not located until 1831. On an otherwise disastrous expedition to Arctic, British explorer James Clark Ross discovered the pole—the spot where a compass needle on a horizontal axis points straight down—on the west coast of Canada's Boothia peninsula. "I must leave it to others to imagine the elation of mind with which we found ourselves now at length arrived at this great object of our ambition," Ross recalled. "Nothing now remained for us but to return home and be happy for the rest of our days."
