Hypochondriac comes ultimately from the Greek word hypokhondria, which literally means “under the cartilage (of the breastbone).” In the late 16th century, when hypochondriac first entered the English language, it referred to the upper abdomen.

The upper abdomen, it turns out, was thought to be the seat of melancholy at a time when the now-outdated medical theory of the four humors (blood, phlegm, yellow bile [choler], and black bile [melancholy]) was accepted as a basis for legitimate health practice. In the 17th century, hypochondriac referred to people who suffered from “depression and melancholy without cause,” though we might suppose from the name of this malady that many depressed patients complained of abdominal pains, which otherwise went undiagnosed. “Vapors,” another archaic disorder connected to the upper abdomen, was used as a euphemism for PMS in a time when such things were not discussed in polite conversation. Because doctors were male at this time, “women’s problems” were largely written off as fits of hysteria (another obsolete medical term of Greek origin from the word for womb).

It wasn’t until the 19th century that hypochondriac described someone who suffered “illness without a specific cause.” This sense is still widely used, though today we diagnose modern hypochondriacs by their overuse of the website WebMD.

Whether March winds and April showers will bring forth May flowers is still a hope away, but the facts behind the month’s name are fortunately more certain.

The name March is derived from the Roman “Martius“ named after Mars, the Roman god of war. In ancient Rome, March 1st marked the first day of spring, which coincided with the beginning of the calendar year and the start of the military campaign season – which may explain why soldiers “march into battle.” The Roman ruler, Numa Pompilius, added January and February to the calendar thus making March the third month of the year. While many have adopted the Gregorian calendar, some cultures and religions still celebrate the start of the New Year on March 1st.

(Is it true there used to be one more month called Mercedonius? The accurate answer is sometimes. Here’s the reason why.)

Hares mate during the month of March and a female hare may be seen “boxing” (striking another hare with their paws) off a male to prevent an act of procreation — hence “Mad as a March hare” – a phrase that appeared for the first time in Sir Thomas More’s “The supplycacyon of soulys,” published in 1529. Charles Lutwidge Dodgson, under the pseudonym Lewis Carroll, also referenced this annual event in 1865’s “Alice’s Adventures in Wonderland“(often shortened to Alice in Wonderland) and the passage: “The March hare… as this is May, it won’t be raving mad – at least not so mad as it was in March.”

The Ides of March is a reference to the date Julius Caesar was stabbed to death in 44 B.C. and is observed on the 15th day of the month. Julius Caesar was many things good and bad, but did he deserve to have the month of July named after him? Read our explanation of the mess that defined the Roman calendar before Julius Caesar, here.

“You’d see ‘em wearin’ their baggies, Huarache sandals, too”

“Baggies” were the boxer-style bathing suits preferred by surfer dudes over the traditional Speedo-type form-fitting model. The extra fabric helped to prevent surfboard wax from painfully ripping out upper-leg hair when the surfer rose from a sitting to a standing position. Huarache is a type of woven leather sandal, one that’s actually closer to a shoe than a sandal.

“Warm smell of colitas rising up through the air”

According to the Eagles’ then-manager, “colitas” was explained to Don Henley and Glenn Frey as literally meaning “little buds” by their Mexican-American road manager, and further as Spanish slang for “marijuana.”

“Scaramouche, Scaramouche, will you do the fandango?” … “Bismillah! No!”

Scaramouche is a traditional clown character featured in Italian commedia dell’arte. He is a stock character in Punch and Judy shows and often gets his head knocked off of his shoulders by Punch. The fandango is a lively couples dance usually accompanied by guitars, hand claps and castanets.

“Bismillah” is an Arabic word that means “in the name of God.” It is used at the head of almost every chapter in the Holy Quran.

Radium was discovered by Marie Curie and her husband Pierre in 1898. In 1903, the Royal Academy of Sciences awarded Marie and Pierre Curie and Henri Becquerel the Nobel Prize in Physics, making Marie the first woman to win the prize. Later, in 1911, she would win her second Nobel for isolating radium, discovering another element (polonium), and for her research into the new phenomenon of radioactivity, a word she coined herself.

By 1910, radium was manufactured synthetically in the U.S. But before the effects of radiation exposure were well understood, radium ended up in a lot of crazy places for its purported magical healing properties and its glow-in-the-dark novelty.

Did Viking helmets have horns? Was Napoleon that short? Was the Roman Vomitorium real? (03:58)

Today I found out, before the 17th century, almost all carrots cultivated were purple.  The modern day orange carrot wasn’t cultivated until Dutch growers in the late 16th century took mutant strains of the purple carrot, including yellow and white carrots and gradually developed them into the sweet, plump, orange variety we have today.

• Maria did not marry Georg von Trapp because she was in love with him. As she said in her autobiography Maria, she fell in love with the children at first sight, not their father. When he asked her to marry him, she was not sure if she should abandon her religious calling but was advised by the nuns to do God’s will and marry Georg. “I really and truly was not in love. I liked him but didn’t love him. However, I loved the children, so in a way I really married the children.  … [B]y and by I learned to love him more than I have ever loved before or after.”
• There were 10, not 7 von Trapp children.
• Georg, far from being the detached, cold-blooded patriarch of the family who disapproved of music, as portrayed in the first half of The Sound of Music, was actually a gentle, warmhearted parent who enjoyed musical activities with his family. While this change in his character might have made for a better story in emphasizing Maria’s healing effect on the von Trapps, it distressed his family greatly.
• The family did not secretly escape over the Alps to freedom in Switzerland, carrying their suitcases and musical instruments. As daughter Maria said in a 2003 interview printed in Opera News, “We did tell people that we were going to America to sing. And we did not climb over mountains with all our heavy suitcases and instruments. We left by train, pretending nothing.”
