How Often Is 'Once in a Blue Moon'? Let Neil deGrasse Tyson Explain

From “lit” to “I can’t even,” lots of colloquialisms make no sense. But not all confusing phrases stem from Millennial mouths. Take, for example, “once in a blue moon”—an expression you’ve likely heard uttered by teachers, parents, newscasters, and even scientists. This term is often used to describe a rare phenomenon—but why?

Even StarTalk Radio host Neil deGrasse Tyson doesn’t know for sure. “I have no idea why a blue moon is called a blue moon,” he tells Mashable. “There is nothing blue about it at all.”

A blue moon is the second full moon to appear in a single calendar month. Astronomy dictates that two full moons can technically occur in one month, so long as the first moon rises early in the month and the second appears around the 30th or 31st. This type of phenomenon occurs every couple years or so. So taken literally, “Once in a blue moon” must mean "every few years"—even if the term itself is often used to describe something that’s even more rare.

Attention Nintendo Fans: You're Pronouncing 'NES' All Wrong

More than 30 years after its debut, the NES re-entered the public consciousness when Nintendo released the NES Classic. Its return has prompted a new generation of gamers to ask some important questions, like "When will the NES be back in stock?," "They're selling for how much on eBay?," and "How do you pronounce NES anyway?" Lifehacker has the answer to that last query, and it may be different than what you expect.

This screenshot from the Japanese version of WarioWare Gold for 3DS, shared on Twitter by gamer Kyle McLain, holds a major clue to the console name's true pronunciation. Above the English abbreviation NES, Nintendo has included the Japanese characters “ne” and “su.” Together, they make what NES would sound like if it was pronounced "ness" in Japan.

That would make NES an acronym, not an initialism, but there's still some evidence in support of the latter camp. This video was shared by Twitter user Doctor_Cornelius in reply to the original Tweet, and it features a vintage American Nintendo commercial. At the 1:58 mark, the announcer can clearly be heard saying "The Power Glove for your N-E-S."

So which way is correct? Nintendo is a Japanese company, so gamers may have reason to trust the instincts of the Japanese marketers over the American ones. Either way, if you want to stick with whatever pronunciation you've been saying this whole time, the company is technically on your side.

Buy Books and Never Read Them? There's a Japanese Word for That

In English, stockpiling books without ever reading them might be called being a literary pack rat. People in Japan have a much nicer term for the habit: tsundoku.

According to the BBC, the term tsundoku derives from the words tsumu ("to pile up") and doku ("to read"), and it has been around for more than a century. One of its earliest known print appearances dates back to 1879, when a Japanese satirical text playfully referred to a professor with a large collection of unread books as tsundoku sensei.

While accusing someone of caring more about owning books than reading them may sound insulting, in Japan, the word tsundoku doesn't carry any negative connotations. Tsundoku isn't the same as hoarding books obsessively. People who engage in tsundoku at least intend to read the books they buy, in contrast to people with bibliomania, who collect books just for the sake of having them.

There are many reasons someone might feel compelled to purchase a physical book. Though e-books are convenient, many people still prefer hard copies. Physical books can be easier on the eyes and less distracting than e-readers, and people who read from ink-and-paper texts have an easier time remembering a story's timeline than people who read digital books. Of course, the only way to enjoy those benefits is by pulling a book off your shelf and actually reading it—something people practicing tsundoku never get around to.
