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.

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.

Where Exactly Is Anne Boleyn's Body?

Anne Boleyn had a pretty rough 1536. First, a pregnant Anne discovered her husband was having an affair with Jane Seymour, one of her ladies in waiting. Some believe the shock and betrayal caused Anne to suffer a miscarriage in early February—and at least one report says it was the boy Henry VIII so desperately wanted. The birth of a healthy baby boy probably would have saved Anne’s life, but since she was unable to produce a male heir to the throne, her husband decided to simply replace her. Anne found herself imprisoned in the Tower of London on May 2, accused of adultery, incest, and high treason. Her marriage was annulled on May 17, and she was relieved of her head on May 19.

To add insult to all of this injury, no one bothered to give Anne a proper burial. Though the execution itself was meticulously planned, it hadn't occurred to anyone that there was no coffin until after Anne’s head rolled. After rummaging around the grounds, someone eventually scrounged up an old arrow chest to cram the corpse into.

She and her brother were then buried in an unmarked grave in front of the altar at St. Peter’s ad Vincula, within the Tower of London, and then completely forgotten about for the next 300-plus years. It wasn’t until Tower repairs in 1876 that Anne resurfaced—maybe.

Bones were discovered under the altar during the renovations, and based on the circumstantial evidence of an arrow chest coffin, bones belonging to a slender woman between the ages of 25 and 35, and a decapitated head, it was assumed that the remains belonged to Anne. However, Henry VIII disposed of his fifth wife Katherine Howard in the exact same manner, and had her corpse thrown in with the pile of bodies accumulating under the altar. Still other women were decapitated and buried in the same place, including Margaret Pole, Countess of Salisbury; Lady Jane Grey; and Lady Rochford.

Despite the fact that five headless women were buried there at one point, only four bodies were uncovered. The remains of Katherine Howard had seemingly disappeared, perhaps due to the quicklime found in the graves. Regardless of the uncertainty, Queen Victoria had the bodies exhumed and placed in individual coffins. A plaque with the name of the person thought to be inside was affixed to each coffin, and each one was given a proper reburial underneath the altar.

Is it really Anne Boleyn who lies beneath, or did workers really find someone else, giving credence to the theory that Anne Boleyn’s relatives had her body secretly reburied elsewhere? Unless DNA testing is performed on the remains, we’ll probably never know.

The Very Real Events That Inspired Game of Thrones's Red Wedding

Ask any Game of Thrones fan to cite a few of the show's most shocking moments, and the so-called "Red Wedding" from season 3's "The Rains of Castamere" episode will likely be at the top of their list. The events that unfolded during the episode shocked fans because of their brutality, but what might be even more surprising to know is that the episode was based on very real events.

Author George R.R. Martin has said that the inspiration for the matrimonial bloodbath is based on two dark events in Scottish history: the Black Dinner of 1440 and 1692's Massacre of Glencoe. “No matter how much I make up, there’s stuff in history that’s just as bad, or worse,” Martin told Entertainment Weekly in 2013. And he’s absolutely right. See for yourself.

The Massacre of Glencoe

In 1691, all Scottish clans were called upon to renounce the deposed King of Scotland, James VII, and swear allegiance to King William of Orange (of William and Mary fame). The chief of each clan had until January 1, 1692, to provide a signed document swearing an oath to William. The Highland Clan MacDonald had two things working against them here. First of all, the Secretary of State, John Dalrymple, was a Lowlander who loathed Clan MacDonald. Secondly, Clan MacDonald had already sworn an oath to James VII and had to wait on him to send word that they were free to break that oath.

Unfortunately, it was December 28 before a messenger arrived with this all-important letter from the former king. That gave Maclain, the chief of the MacDonald clan, just three days to get the newly-signed oath to the Secretary of State.

Maclain was detained for days when he went through Inveraray, the town of the rival Clan Campbell, but still managed to deliver the oath, albeit several days late. The Secretary of State’s legal team wasn't interested in late documents. They rejected the MacDonalds's sworn allegiance to William, and set plans in place to cut the clan down, “root and branch.”

In late January or early February, 120 men under the command of Captain Robert Campbell arrived at the MacDonalds's in Glencoe, claiming to need shelter because a nearby fort was full. The MacDonalds offered their hospitality, as was custom, and the soldiers stayed there for nearly two weeks before Captain Drummond arrived with instructions to “put all to the sword under seventy.”

After playing cards with their victims and wishing them goodnight, the soldiers waited until the MacDonalds were asleep ... then murdered as many men as they could manage. In all, 38 people—some still in their beds—were killed. At least 40 women and children escaped, but fleeing into a blizzard blowing outside as their houses burned down meant that they all died of exposure.

The massacre was considered especially awful because it was “Slaughter Under Trust.” To this day, the door at Clachaig Inn in Glen Coe has a sign on the door that says "No hawkers or Campbells."

The Black Dinner

In November of 1440, the newly-appointed 6th Earl of Douglas, who was just 16, and his little brother David, were invited to join the 10-year-old King of Scotland, James II, for dinner at Edinburgh Castle. But it wasn’t the young King who had invited the Douglas brothers. The invitation had been issued by Sir William Crichton, Chancellor of Scotland, who feared that the Black Douglas (there was another clan called the Red Douglas) were growing too powerful.

As legend has it, the children were all getting along marvelously, enjoying food, entertainment and talking until the end of the dinner, when the head of a black bull was dropped on the table, symbolizing the death of the Black Douglas. The two young Douglases were dragged outside, given a mock trial, found guilty of high treason, and beheaded. It’s said that the Earl pleaded for his brother to be killed first so that the younger boy wouldn’t have to witness his older brother’s beheading.

Sir Walter Scott wrote this of the horrific event:

"Edinburgh Castle, toune and towre,
God grant thou sink for sin!
And that e'en for the black dinner
Earl Douglas gat therein."
