Obscenity vs. Profanity vs. Vulgarity: What's the Difference?

Original image

bubble.gifThe Dilemma: You just stubbed your toe or opened your 401(k) statement and you want to let loose with some language that would make a sailor blush. Which category do those colorful words fall under?


People You Can Impress: Sailors, legal scholars, linguists.


The Quick Trick: Who's mad at you for saying what you said? Obscenity gets you in trouble with the law. Profanity gets you in trouble with religious folks and The Powers That Be. Vulgarity just gets you in trouble with your mother.

The Explanation: Obscenity (from the Latin obscenus, meaning "foul, repulsive, detestable") generally covers sexual or scatological references to the body or bodily functions (i.e. F*&k and s#$t). The term is also used in a legal context to describe expressions (whether words, images or actions) that offend the sexual morality of a given time and place and are not protected by the First Amendment.

In this legal context, though, we're still grappling with what counts as obscene and what does not.

Former Supreme Court Justice Potter Stewart once famously said that he couldn't define what kind of material was obscene, but he knew it when he saw it. We've came little further with the Miller Test, which comes from the 1973 ruling of the Supreme Court case of Miller v. California. If an expression meets these three criteria, then it's obscene:

1. The average person, applying contemporary community standards, would find that the work, taken as a whole, appeals to the prurient interest.

2. The work depicts/describes, in a patently offensive way, sexual conduct or excretory functions specifically defined by applicable state law.

3. The work, taken as a whole, lacks serious literary, artistic, political or scientific value.

If the expression fails to meet any one of those criteria, then you're off the hook. "Average person," "community standards," "patently offensive" and "serious value" are all fairly subjective terms, though. Even with the Miller Test, there's no national standard for what classifies as obscene, and distinctions between protected expression and unprotected obscene expression vary among federal court districts.

If you're being profane, you don't need to worry about the Supreme Court (it has no legal definition), but if you believe in an immortal soul, you might be in trouble. Profane (from the Latin profanes, meaning "outside the temple") originally referred to things not belonging to the church. Later it meant blasphemy, sacrilege or taking the Lord's name in vain (we just call that blasphemy now).

Today, profanity is an expression that is specifically offensive to members of a religious group. The definition also extends to expressions that are scatological, derogatory, racist, sexist, or sexual. What is and isn't profane largely depends on the context and the company you keep.

Finally, vulgarity (from the Latin vulgis, meaning "the common people,"), which used to refer to text written in a vernacular instead of Latin, has two definitions today, depending on who you ask. For some, vulgarity is generally coarse or crude language. For others, it is more specifically the act of substituting a coarse word in a context where a more refined expression would be expected.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

These $425 Jeans Can Turn Into Jorts

Opening Ceremony

Modular clothing used to consist of something simple, like a reversible jacket. Today, it’s a $425 pair of detachable jeans.

Apparel retailer Opening Ceremony recently debuted a pair of “2 in 1 Y/Project” trousers that look fairly peculiar. The legs are held to the crotch by a pair of loops, creating a disjointed C-3PO effect. Undo the loops and you can now remove the legs entirely, leaving a pair of jean shorts in their wake. The result goes from this:

To this:

The company also offers a slightly different cut with button tabs in black for $460. If these aren’t audacious enough for you, the Y/Project line includes jumpsuits with removable legs and garter-equipped jeans.
