Do you have an uncontrollable desire to jump up and dance while watching “Dancing with the Stars”? Perhaps it’s not the music and excitement, but tarantism. In the 17th century, this urge to engage in a frenzied whirling dance, accompanied by nervous bouts of melancholy and hysteria, spread widely in southern Italy. The syndrome’s name comes from an energetic dance, the tarantella, a supposed cure for the venomous bite of a tarantula. The officially dubbed “tarantism” followed a 1518 outbreak when a woman danced for days in the streets of Strasbourg. Before long, dozens of ... Read More
Linguistic Myths and Adventures in Etymology
The alarm went off. What does that mean? Recently, a friend who is learning English couldn’t quite figure it out. Isn’t the alarm going on, not off, he asked. Comprehending such phrases is often one of the more difficult steps in learning a language. These idiomatic expressions are collections of words that mean something different than each word’s dictionary definition. For example, “that barking dog next door is driving me up the wall,” if taken literally, could mean that the neighbor’s poodle has recently earned a driver’s license and is using a car to accelerate up the ...

Presidents’ Day: Just Another Presidential Fable
In the United States, February brings “Presidents’ Day” and some familiar stories, such as George Washington chopping down ye olde cherry tree, circulate anew. Sweet as it may sound about not lying to one’s father, this story is not true. Nor, to bite into a story of more recent vintage, did he have wooden teeth. Let’s skeptically consider a few of the many fables that regularly appear about current and past presidents, and critically think about the purposes they may serve. First, we need to address the initial fable of a “Presidents’ Day.” Yes, Martha, there is no such ... Read More
Numerology Doesn’t Know the Score

We entered the new year with all sorts of expectations and excitement, but I’m sure none compared to the chills from realizing 2012 will see the last major numerical date event — using the Gregorian calendar — for almost another century: December 12, 2012 — better represented as 12/12/12. I know, just a few months ago, we achieved 11/11/11. But not until 2101 will we be able to write 01/01/01, just as we did on that numerically glorious day of January 1, 2001. Disappointing I know, but should we celebrate or cower? Is this the end of the world, as the Mayans sort-of predicted? No, ... Read More
Full Moon Myths Leave Skeptics Howling
A stock image of the holiday season is a night scene of Santa and his reindeers silhouetted across a full moon, his sleigh packed with presents ready to be delivered throughout the evening. While this joyous image fits some of our romantic notions of being moonstruck, it contradicts some widely held beliefs about the negative effects of full moons. (And never mind that the odds of experiencing a full moon on Christmas Eve itself are very small: the last one was in 2007 and the next may not appear until 2026.) A teacher I know, complaining about her students’ boisterous behavior in the ... Read More
