What's the Difference Between a Button-Up and a Button-Down Shirt?

As you probably already know, collared shirts with buttons running down the middle are typically referred to as either button-ups or button-downs. Some people have a strong preference for one term over the other; others use them interchangeably, believing (erroneously) that they’re synonymous.

Last November, model and author Chrissy Teigen took to Twitter and asked in a poll, “Is it a button up or button down?” Of the 220,000-plus respondents, 66 percent said button-up, and 34 percent said button-down. On the other hand, button-down appears to be the more searched-for term overall, according to Google Trends.

So which one is right? As it turns out, the two terms actually refer to two different garments. The button-down shirt came to be in the late 1800s, thanks to British polo players. Their uniform typically consisted of flannel pants, a wool sweater, and a long-sleeve shirt—all in white. It looked pretty snappy, but the players quickly became irritated by their collars flapping in the wind as they rode around on their horses.

According to Charles Panati’s book on the Extraordinary Origins of Everyday Things, “Players routinely asked seamstresses to batten down their collars, and two buttons became the most popular solution to the problem.” This was called a polo collar at the time, and the style was soon popularized by John Brooks, whose father founded the Brooks Brothers clothing line. (Oddly, polo shirts as we know them today were actually made for tennis, not polo.)

This is all to say that button-down shirts have buttons attached to the collar, while button-up shirts do not. Here’s where it gets a little confusing, though: All shirts with buttons can be called button-ups. However, only some button-ups (the ones with buttons on the collars) can be called button-downs.

As Megan Collins of Style Girlfriend explained it to the Today show, it’s kind of like how “an apple is a fruit, but not all fruits are apples.”

If you ever get mixed up, just keep in mind that the collars of a button-down can be buttoned down. As for their sartorial differences, button-down shirts are less common these days, especially among women's styles. They also tend to be slightly more casual than shirts with free-flapping collars, according to Collins.

If ties aren't your thing, but you're still trying to win style points, you should stick with the more versatile button-up shirt, according to Mainline Menswear.

It's difficult to think of a hobby or job that doesn’t involve some element of coding in its execution. Are you an Instagram enthusiast? Coding and algorithms are what bring your friends' posts to your feed. Can’t get enough Mental Floss? Coding brings the entire site to life on your desktop and mobile screens. Even sorting through playlists on Spotify uses coding. If you're tired of playing catch-up with all the latest coding techniques and principles, the 2020 Python Programming Certification Bundle is on sale for $49.99 to teach you to code, challenge your brain, and boost your resume to get your dream job.

Basically, coding is how people speak to computers (cue your sci-fi vision of a chat with a creepy, sentient computer), and while it does sound a bit futuristic, the truth is that people are talking to computers every day through a program called Python. The 2020 Python Programming Training Certification Bundle will teach you how to build web applications, database applications, and web visualizations in the world’s most popular programming language.

Python is also the language computers are using to communicate back to programmers. You’ll learn how Jupyter Notebook, NumPy, and pandas can enhance data analysis and data visualization techniques with Matplotlib.

Think back to your creepy, sci-fi visual from earlier; was it some form of artificial intelligence? Contrary to what you may have seen in the movies, artificial intelligence is something you can learn to create yourself. In the Keras Bootcamp, you’ll learn how to create artificial neural networks and deep-learning structures with Google’s powerful Deep Learning framework.

Coding is associated with endless text, numbers, and symbols, but the work code is performing is hardly limited to copy. Dig deep into image processing and computer vision tasks with sessions in OpenCV. You’ll give yourself an extra edge when you can use Python for sifting through information and implement machine learning algorithms on image classification.

Explore coding education with the bundle’s 12 courses, spanning from beginner to advanced levels, to elevate your skillset from home. The 2020 Python Programming Certification Bundle is on sale for $49.99.

Why Did Noon Used to Mean 3 p.m.?

3 p.m. is basically noon for people who wake up at 12 p.m.

If you’re a late sleeper, you might find yourself thinking 12 p.m. seems way too early to be considered midday, and the word noon would much better describe, say, 3 p.m. It turns out that ancient Romans would have agreed with you, if only for etymological reasons.

As Reader’s Digest explains, the days in ancient Rome were split into four periods of three hours each. The first hour was at sunrise around 6 a.m.—called prime, for first—followed by 9 a.m. (terce, denoting the third hour), 12 p.m. (sext, for sixth), and 3 p.m. (none, for ninth).

According to Merriam-Webster, Middle and Old English borrowed the time-keeping tradition, along with the Latin word for ninth, which was changed to nōn and eventually noon. Though we’re not sure exactly when or why noon started referring to 12 p.m. instead of 3 p.m., it could have something to do with Christian prayer traditions. In the Bible, Jesus’s crucifixion is said to have taken place at the ninth hour, and that’s when worshippers partook in their second of three daily prayers; the others were in the morning and evening. It’s possible that hungry monks were behind noon’s gradual shift from 3 p.m. to 12 p.m.—since their daily fast didn’t end until after the midday prayer, they had a built-in motive for moving it earlier.

While we didn’t exactly stay true to the original Latin meaning of noon, there’s another important remnant of ancient Rome hiding in the way we tell time today. Romans referred to 12 p.m. as meridiem, for midday, and so do we. A.M. is an abbreviation for ante meridiem, or before midday, and P.M. means post meridiem, or after midday.
