11 Elegant Facts About Top Hats

From the patriotic number that Uncle Sam sports to the titular topper in Dr. Seuss’ The Cat in the Hat, top hats showcase personality and style—and their history is just as colorful as the people who wear them. 

1. THEY CAN BE COOL (LITERALLY).

A 1911 Popular Mechanics marveled over a new invention, an electric fan built for use inside of top hats. Flipped on with a switch at the brim, the fan “keeps head cool in hot weather.” The battery was built to last for several days of cooling, and replacements were only 15 cents a pop (that's a little under $4 today). 

Popular Science, much like Popular Mechanicstook on top hats as an item of interest. In a July 1930 issue, one writer mused about the storage potential of hats if a pocket was inserted into them. Women’s hats could store everything from a powder puff to a needle and thread, and for men, “quite a lot could be easily hidden away in a silk top hat.”

2. THEY INSPIRED AN INSULT.

Top hats gave rise to the phrase “high hat,” used to refer to someone who is snobby or too good for something (like the kind of aristocrat that wore a top hat in the trend’s early years).

3. "MAD AS A HATTER" HAS NOTHING TO DO WITH ALICE.

Lewis Carroll’s the Mad Hatter in Alice’s Adventures in Wonderland was known for dressing to the nines with a grandiose top hat, but interestingly, the character wasn’t the origin of the phrase “mad as a hatter.” The term dates back to the 18th century, when factories used mercury in the production of felt, a common material for making all types of hats. Factory workers exposed too frequently to the metal developed mercury poisoning, which induced a type of dementia, or “mad hatter.”

4. THEY'VE BEEN POPPING OUT WHITE RABBITS FOR 200 YEARS.

The first time a bunny mysteriously popped out of a top hat was in 1814, when French magician Louis Comte supposedly performed the now-classic magic trick for the first time.

5. NIXON WORE ONE.

Well into the 20th century, it was common for presidents to wear top hats to look extra posh at their inaugurations. President Richard Nixon was the last president to be inaugurated wearing a top hat, and no president has donned a cap for the big day since.

6. SOME WERE COLLAPSIBLE.

The most portable of top hats, the gibus, was invented in 1840 by its namesake, Antoine Gibus. The spring-loaded topper was built to be folded up and put away when not worn, and could pop back to full-size when a gentleman was ready to head outside. They were also known as opera hats, because they were easy to condense and store under your seat while you took in a show.

7. ONE MOGUL RAISED THE ROOF (IN ORDER TO FIT HIS TOPPER).

It’s rumored that financier J.P. Morgan had a custom-made limousine built for himself with an extra-high roof that allowed him to ride in style without having to take off his top hat (and presumably, expose his balding head).

8. THEY MAKE FEBRUARY 2 A CLASSY AFFAIR.

February 2 is a big day for all of us—it’s when we find out how much longer we (theoretically) have to wait for spring—but it’s also a big day for top hats. The Punxsutawney Groundhog Club, the folks who tote around trusted weather predictor Punxsutawney Phil, break out their top hats every Groundhog’s Day for the big ceremony.

9. THEY'VE GOTTEN PROGRESSIVELY … LOWER.

Top hats have spanned quite a range of heights over the years. Early on, they stood tall (really tall), some reaching up to eight inches high. The Victorian Era was a more subdued time for top hats, with tallest hat height only reaching between six and seven inches. And by the time the 1920s rolled around, the headpieces had dwindled to a measly five or so inches, which is the height most top hats are still at today.

10. SLASH DIDN'T PAY FOR HIS.

Slash, the most hardcore of top hat fans, admitted to the Huffington Post a few years ago that he actually shoplifted his iconic hat (along with the belt tied around it).

11. LINCOLN'S HAT FOILED AN ASSASSINATION ATTEMPT.

President Abraham Lincoln’s hat may have been his signature look, but it also may have saved his life. In 1864, someone fired a shot at Lincoln as he was riding a horse near his summer home, not too far from the White House. It knocked his hat off, and the soldiers who picked it up remarked it had a bullet hole in the top. Lincoln was wearing his trademark top hat the night he died as well, leaving it on the floor next to him during the performance at the Ford Theater.

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!

10 Facts About the Tomb of the Unknown Soldier
May 29, 2017

Library of Congress

On Veterans Day, 1921, President Warren G. Harding presided over an interment ceremony at Arlington National Cemetery for an unknown soldier who died during World War I. Since then, three more soldiers have been added to the Tomb of the Unknowns (also known as the Tomb of the Unknown Soldier) memorial—and one has been disinterred. Below, a few things you might not know about the historic site and the rituals that surround it.

1. THERE WERE FOUR UNKNOWN SOLDIER CANDIDATES FOR THE WWI CRYPT.

To ensure a truly random selection, four unknown soldiers were exhumed from four different WWI American cemeteries in France. U.S. Army Sgt. Edward F. Younger, who was wounded in combat and received the Distinguished Service Medal, was chosen to select a soldier for burial at the Tomb of the Unknowns in Arlington. After the four identical caskets were lined up for his inspection, Younger chose the third casket from the left by placing a spray of white roses on it. The chosen soldier was transported to the U.S. on the USS Olympia, while the other three were reburied at Meuse Argonne American Cemetery in France.

2. SIMILARLY, TWO UNKNOWN SOLDIERS WERE SELECTED AS POTENTIAL REPRESENTATIVES OF WWII.

One had served in the European Theater and the other served in the Pacific Theater. The Navy’s only active-duty Medal of Honor recipient, Hospitalman 1st Class William R. Charette, chose one of the identical caskets to go on to Arlington. The other was given a burial at sea.

3. THERE WERE FOUR POTENTIAL KOREAN WAR REPRESENTATIVES.

The soldiers were disinterred from the National Cemetery of the Pacific in Hawaii. This time, Army Master Sgt. Ned Lyle was the one to choose the casket. Along with the unknown soldier from WWII, the unknown Korean War soldier lay in the Capitol Rotunda from May 28 to May 30, 1958.

4. THE VIETNAM WAR UNKNOWN WAS SELECTED ON MAY 17, 1984.

Medal of Honor recipient U.S. Marine Corps Sgt. Maj. Allan Jay Kellogg, Jr., selected the Vietnam War representative during a ceremony at Pearl Harbor.

5. BUT THE VIETNAM VETERAN WASN'T UNKNOWN FOR LONG.

Wikipedia // Public Domain

Thanks to advances in mitochondrial DNA testing, scientists were eventually able to identify the remains of the Vietnam War soldier. On May 14, 1998, the remains were exhumed and tested, revealing the “unknown” soldier to be Air Force 1st Lt. Michael Joseph Blassie (pictured). Blassie was shot down near An Loc, Vietnam, in 1972. After his identification, Blassie’s family had him moved to Jefferson Barracks National Cemetery in St. Louis. Instead of adding another unknown soldier to the Vietnam War crypt, the crypt cover has been replaced with one bearing the inscription, “Honoring and Keeping Faith with America’s Missing Servicemen, 1958-1975.”

6. THE MARBLE SCULPTORS ARE RESPONSIBLE FOR MANY OTHER U.S. MONUMENTS. 

The Tomb was designed by architect Lorimer Rich and sculptor Thomas Hudson Jones, but the actual carving was done by the Piccirilli Brothers. Even if you don’t know them, you know their work: The brothers carved the 19-foot statue of Abraham Lincoln for the Lincoln Memorial, the lions outside of the New York Public Library, the Maine Monument in Central Park, the DuPont Circle Fountain in D.C., and much more.

7. THE TOMB HAS BEEN GUARDED 24/7 SINCE 1937. 

Tomb Guards come from the 3rd U.S. Infantry Regiment "The Old Guard". Serving the U.S. since 1784, the Old Guard is the oldest active infantry unit in the military. They keep watch over the memorial every minute of every day, including when the cemetery is closed and in inclement weather.

8. BECOMING A TOMB GUARD IS INCREDIBLY DIFFICULT.

Members of the Old Guard must apply for the position. If chosen, the applicant goes through an intense training period, in which they must pass tests on weapons, ceremonial steps, cadence, military bearing, uniform preparation, and orders. Although military members are known for their neat uniforms, it’s said that the Tomb Guards have the highest standards of them all. A knowledge test quizzes applicants on their memorization—including punctuation—of 35 pages on the history of the Tomb. Once they’re selected, Guards “walk the mat” in front of the Tomb for anywhere from 30 minutes to two hours, depending on the time of year and time of day. They work in 24-hour shifts, however, and when they aren’t walking the mat, they’re in the living quarters beneath it. This gives the sentinels time to complete training and prepare their uniforms, which can take up to eight hours.

9. THE HONOR IS ALSO INCREDIBLY RARE.

The Tomb Guard badge is the least awarded badge in the Army, and the second least awarded badge in the overall military. (The first is the astronaut badge.) Tomb Guards are held to the highest standards of behavior, and can have their badge taken away for any action on or off duty that could bring disrespect to the Tomb. And that’s for the entire lifetime of the Tomb Guard, even well after his or her guarding duty is over. For the record, it seems that Tomb Guards are rarely female—only three women have held the post.

10. THE STEPS THE GUARDS PERFORM HAVE SPECIFIC MEANING.

Everything the guards do is a series of 21, which alludes to the 21-gun salute. According to TombGuard.org:

The Sentinel does not execute an about face, rather they stop on the 21st step, then turn and face the Tomb for 21 seconds. They then turn to face back down the mat, change the weapon to the outside shoulder, mentally count off 21 seconds, then step off for another 21 step walk down the mat. They face the Tomb at each end of the 21 step walk for 21 seconds. The Sentinel then repeats this over and over until the Guard Change ceremony begins.
