Today is a Holiday in Honor of the World’s Most Remarkable Alphabet

Happy Hangul Day! October 9th is a South Korean national holiday held in honor of the invention of the Korean writing system, which experts have called the most “scientific” (plus the most “ingenious,” “rational,” “subtle,” “simple,” “efficient,” and “remarkable”) writing system ever devised.

It was created in the 1440s by a committee of scholars commissioned by King Sejong. King Sejong, also known as Sejong the Great, was a fervent supporter of literature, science, and technology in his day. Some 200 years before the founding of the first scientific academy of the enlightenment, Sejong convened a group of handpicked scholars for his “Hall of Worthies.” One of their major assignments was to come up with a writing system to represent the Korean language.

At that time, Korean was written with Chinese characters. Learning to use Chinese characters, along with the adjustments required in adapting them to the Korean language, was an arduous process, requiring years of education and training. This meant that literacy was only available to a tiny elite. Sejong wanted to open literacy to the general population, but that would require a system that was easier to learn.

The system Sejong’s worthies devised used a combination of alphabetic and syllabic approaches. There were independent symbols for consonants and vowels, but they were grouped into syllables when written. You can see this in the modern form for the word “hangul” (pronounced ‘hangeul’):

Each syllable is grouped into a square character

한 (han) 글 (geul)

Each of those characters is composed of symbols for individual sounds

ㅎ h + ㅏ a + ㄴ n =  한 (han)
ㄱ g + ㅡ eu + ㄹ l = 글 (geul)
 

The system provides a simple, compact packaging of information, easy to read and to learn. According to the postscript of the original description of hangul, "a wise man can acquaint himself with them before the morning is over; a stupid man can learn them in the space of 10 days."

What makes the system especially scientific is that it only distinguishes those sounds which are important for the language. Its symbols reflect psychologically relevant features. For example ㄱ g and ㅋ k are basically the same sound, a consonant formed by a closure at the back of the mouth, except that there is a stronger burst of air with the k. (This distinction holds in English as well. Try pronouncing them one after the other.) In hangul, they are also the same symbol, with the air-burst difference represented by an additional line. The same kind of difference holds between ㄷ d and ㅌ t. They are both formed by contact between the tongue and area behind the upper teeth, but t has a stronger burst of air, which is represented by the same extra line in the symbol. Other distinctive features of the language are represented with similar consistency.

Unlike most writing systems, which developed over long periods of time and took on various inconsistencies in the process, the hangul system was consciously engineered and handed down all at once by a royal proclamation in 1446. The date of that proclamation, October 9th, became a national holiday in 1945 (North Korea celebrates it on January 15th, which is considered the creation date). In 1991, because of economic concerns about workers having too many days off, the holiday was eliminated.

But in 2013, for the first time in 22 years, Hangul Day was reinstated as a national holiday. Celebrate by learning to read hangul. You can also play with this hangul generator, but if you use it to see how you might write your name, please do not run off to the tattoo parlor with the result. The proper use of hangul requires a proper knowledge of Korean, the language for which it was specifically, and quite perfectly, designed.

Turn Your LEGO Bricks Into a Drone With the Flybrix Drone Kit

Now more than ever, it’s important to have a good hobby. Of course, a lot of people—maybe even you—have been obsessed with learning TikTok dances and baking sourdough bread for the last few months, but those hobbies can wear out their welcome pretty fast. So if you or someone you love is looking for something that’s a little more intellectually stimulating, you need to check out the Flybrix LEGO drone kit from Fat Brain Toys.

What is a Flybrix LEGO Drone Kit?

The Flybrix drone kit lets you build your own drones out of LEGO bricks and fly them around your house using your smartphone as a remote control (via Bluetooth). The kit itself comes with absolutely everything you need to start flying almost immediately, including a bag of 56-plus LEGO bricks, a LEGO figure pilot, eight quick-connect motors, eight propellers, a propeller wrench, a pre-programmed Flybrix flight board PCB, a USB data cord, a LiPo battery, and a USB LiPo battery charger. All you’ll have to do is download the Flybrix Configuration Software, the Bluetooth Flight Control App, and access online instructions and tutorials.

Experiment with your own designs.

The Flybrix LEGO drone kit is specifically designed to promote exploration and experimentation. All the components are tough and can totally withstand a few crash landings, so you can build and rebuild your own drones until you come up with the perfect design. Then you can do it all again. Try different motor arrangements, add your own LEGO bricks, experiment with different shapes—this kit is a wannabe engineer’s dream.

For the more advanced STEM learners out there, Flybrix lets you experiment with coding and block-based coding. It uses an arduino-based hackable circuit board, and the Flybrix app has advanced features that let you try your hand at software design.

Who is the Flybrix LEGO Drone Kit for?

Flybrix is a really fun way to introduce a number of core STEM concepts, which makes it ideal for kids—and technically, that’s who it was designed for. But because engineering and coding can get a little complicated, the recommended age for independent experimentation is 13 and up. However, kids younger than 13 can certainly work on Flybrix drones with the help of their parents. In fact, it actually makes a fantastic family hobby.

Why Are Common Graves Called Potter’s Fields?

For centuries, regions around the world have maintained common graves called potter’s fields, where they bury unidentified victims and impoverished citizens who couldn’t afford their own cemetery plots. The term potter’s field has been around for just as long.

The earliest known reference to a potter’s field is from the Gospel of Matthew, which historians believe was written sometime during the 1st century. In it, a remorseful Judas gives the 30 silver coins he was paid for betraying Jesus back to the high priests, who use it to purchase a “potter’s field” where they can bury foreigners. It’s been speculated that the priests chose land from a potter either because it had already been stripped of clay and couldn’t be used for farming, or because its existing holes and ditches made it a particularly good place for graves. But Matthew doesn’t go into detail, and as the Grammarphobia Blog points out, there’s no evidence to prove that the original potter’s field was ever actually used for its clay resources—it could’ve just been a parcel of land owned by a potter.

Whatever the case, the term eventually caught on as English-language versions of the Bible made their way across the globe. In 1382, John Wycliffe translated it from Latin to Middle English, using the phrase “a feeld of a potter,” and William Tyndale’s 1526 Greek-to-English translation of the passage featured “a potters felde,” which was altered slightly to “potters field” in King James’s 1611 edition.

Around the same time, a new definition of potter was gaining popularity that had nothing to do with pottery—in the 16th century, people began using the word as a synonym for tramp or vagrant. According to the Oxford English Dictionary, it was first written in a 1525 Robin Hood tale, and William Wordsworth mentioned it in his 1798 poem “The Female Vagrant.” It’s likely that this sense of the word helped reinforce the idea that a potter’s field was intended for the graves of the unknown.

It’s also definitely not the only phrase we’ve borrowed from the Bible. From at your wit’s end to a fly in the ointment, here are 18 everyday expressions with holy origins.
