7 Things You Should Know About The Indy 500

Original image

Most Americans only pay attention to open-wheel racing one Sunday out of the year. Although the sport doesn't have a Nascar-like spot in the country's heart, the Indianapolis 500 manages to generate fan interest—only fitting for an event that's nicknamed "The Greatest Spectacle in Racing." Whether this year's 92nd running of the Indy 500 is your first time watching the race or a beloved annual tradition, the great spectacle may have a few confusing moments. We've tried to answer some of the inevitable questions for you.


Why is the Indianapolis Motor Speedway called "the Brickyard"?
Because the original racing surface of the track didn't work. When the Speedway opened in 1909, its track was made of crushed stone and tar. This mixture was even less functional than it sounds; when racing started several drivers suffered fatal crashes due to the unstable track. The Speedway's owners wanted to address this problem quickly, so they replaced the track with 3.2 million paving bricks. Thus, the track was nicknamed "the Brickyard."

By 1936, though, the bricks were starting to wear down, and certain patches were paved over. Repairs gradually covered more bricks until 1961, when pavers covered the rest of the track, leaving only a three-foot strip of brick at the start/finish line. This narrow swath of bricks is till visible on the track, although the bricks themselves are occasionally switched out due to wear. In 1996, Nascar driver Dale Jarrett and his crew gave birth to a new tradition when they kissed the bricks after winning the Brickyard 400, the track's premiere stock-car race. Indy 500 winners have since taken to smooching the masonry, starting with Gil de Ferran after his 2003 win.

What the heck is a Carb Day?

Indy 500 preparations are known as "the Month of May" in racing circles because of the painstaking work that goes into perfecting each car before the green flag drops. Due to the long lead-in time, many of the pre-race days have nicknames and have become events of their own.

Since the field is limited to 33 cars, drivers must qualify for a spot in the race. The pole day qualifying determines not just who will drive in the race, but in what position they'll start. The final practice day before qualifying is known as "Fast Friday," because teams really open up their cars and take the speediest practice laps they can.

"Fast Friday" is followed by the Pole Day time trials in which drivers vie for starting their sports and starting positions in the race. When the dust settled after Pole Day this year, Scott Dixon had claimed the top starting spot in the race; he pocketed a cool $100,000 just for winning the pole.

After two more days of qualifying comes "bump day," or the last day of qualifying. Once 33 drivers have posted qualifying times to fill out the field, any driver who then wants to earn a spot in the race has to post a qualifying time faster than the slowest qualifier currently in the field. The slowest driver is then "bumped" out of the field.

The Friday before the race is known as Carb Day. Carburetion Day, as it was originally known, historically gave teams a chance to calibrate their carburetors for race-day conditions. However, due to the rise of fuel injection no car with a carburetor has been in the field since 1963, and today Carb Day is largely a final chance for drivers to practice in their race-day cars. Pit crews also compete in a pit stop challenge competition on Carb Day.

What songs are sung before the race?
Florence.jpgThe Purdue University All-American Marching Band plays a number of signature songs before each year's race, including "Stars and Stripes Forever" and Indiana's state song, "On the Banks of the Wabash." The signature song, though, is "Back Home Again in Indiana," a beloved tribute to the Hoosier state. The song itself might not be familiar to you, but the crooner who belts it out probably is. Jim Nabors, who played Gomer Pyle on The Andy Griffith Show and Gomer Pyle, U.S.M.C., has performed the song most years since 1972. Illness kept him out of last year's race, but he's set to make a triumphant return this year. Since the 1940s, organizers have also released thousands of balloons from an infield tent during the singing of "Back Home Again in Indiana," adding an extra visual flair to the tradition.

If that's not enough Nick-at-Nite-era sitcom star power for you, then you'll be pleased to learn that Florence Henderson, native Hoosier and matriarch of The Brady Bunch, will once again sing "God Bless America," a song she's performed every year since the early 1990s.

Why are the cars moving at the race's start?
Although rolling starts are common in racing now, Indy 500 organizers claim the use of a pace car originated with the race's first running in 1911. Speedway founder Carl Fisher was supposedly worried that having the large field of racers start from a dead stop would be dangerous, so he suggested that the drivers take a lap at a low speed behind a pace car. At the end of this practice lap, the pace car would leave the track, and the race would begin. The tradition has gradually changed; the pace car now leads the standard 33-car field on two unofficial "parade laps," then on the race's first lap, which is known as the "pace lap."

Although it originated as a safety precaution, the pace car has found its way into Indy's pageantry. The pace car is usually a particularly snazzy American ride (the most frequently used car is the Corvette), and the winner is ceremonially given the keys to a replica following his win. Celebrities have taken the driving duties for the pace car; in recent years Morgan Freeman, Lance Armstrong, and Colin Powell have been behind the wheel. This year two-time winner Emerson Fittipaldi will set the pace in a 2008 Corvette.

indy-trophy.jpgWhat's the deal with the gigantic trophy?
"Gigantic" might actually be an understated description of the Borg-Warner Trophy, which has been awarded to the race's winner since 1936. The sterling silver trophy, which is named after American auto part supply company BorgWarner, stands over five feet tall and weighs over 150 pounds. (In other words, it's taller and heavier than Danica Patrick.) The trophy contains a bas-relief sculpture of every winning driver in Indy 500 history, as well as a gold sculpture of Tony Hulman, the late owner of the racetrack. It's topped with a sculpture of a naked track marshal waving a checkered flag, a sight that's all too familiar to anyone who's ever tried to make a race marshal put on some pants.


Was the trophy always so huge?
No. But in 1986, race organizers ran out of room to put future winners' faces. A large extension was added at the base; it provides ample room to sculpt the winners of every race until 2034. Due to the trophy's value and enormous heft, the winner doesn't actually get to keep it for the year. Instead, since 1988 drivers have been given an 18-inch replica as a memento of their victories.

Why does the winner chug milk in victory lane?
milk.jpgThis tradition exists because three-time winner Louis Meyer was an obedient son. Meyer's mom had told him to drink buttermilk on warm days to cool down. Meyer made a habit of it, and a photographer snapped a picture when he took a long slug of milk in victory lane after winning the 1936 race. An enterprising dairy industry executive saw the picture in the paper and decided to make a bottle of milk part of the standard victory celebration. The tradition got off to a slow start, but it's been an Indy 500 mainstay since 1955. The American Dairy Association now pays a sponsorship to the winner for giving milk such a prime endorsement.

There has been at least one notable exception, though. When Emerson Fittipaldi took the checkered flag in 1993, he eschewed milk in favor of a bottle of orange juice. Was he just confusing his breakfast drinks? Possibly, but some suspected he was trying to boost orange juice consumption since he owned orange groves in his native Brazil. He eventually drank some milk after the orange juice, but later apologized for breaking tradition and donated the dairy sponsorship money to a women's charity.

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!

Whether you want to change your legal name, adopt a new nickname, or simply reinvent your online persona, it's helpful to know the process of resetting your name on Facebook. The social media site isn't a fan of fake accounts, and as a result changing your name is a little more complicated than updating your profile picture or relationship status. Luckily, Daily Dot laid out the steps.

Start by going to the blue bar at the top of the page in desktop view and clicking the down arrow to the far right. From here, go to Settings. This should take you to the General Account Settings page. Find your name as it appears on your profile and click the Edit link to the right of it. Now, you can input your preferred first and last name, and if you’d like, your middle name.

The steps are similar in Facebook mobile. To find Settings, tap the More option in the bottom right corner. Go to Account Settings, then General, then hit your name to change it.

Whatever you type should adhere to Facebook's guidelines, which prohibit symbols, numbers, unusual capitalization, and honorifics like Mr., Ms., and Dr. Before landing on a name, make sure you’re ready to commit to it: Facebook won’t let you update it again for 60 days. If you aren’t happy with these restrictions, adding a secondary name or a name pronunciation might better suit your needs. You can do this by going to the Details About You heading under the About page of your profile.
