Over the Rainbow: The Technicolor Life of the Man Who Created Oz

Original image

By Kelly K. Ferguson

In December 1900, L. Frank Baum was a struggling, 44-year-old writer living in Chicago with his wife and four children. Christmas was only days away, and Baum was desperately searching for a way to buy presents for his family.

On a whim, Baum went downtown to ask his publisher for a royalties' advance for the five books he'd written that year. He walked out with a check for one of the books, and promptly stuck it in his pocket. He didn't bother to take a look at it.

When Baum arrived home, his wife, Maud, was ironing a shirt. He reluctantly handed her the check, and at the same moment, they both discovered that it was for $1,423.98—roughly $40,000 today. Paralyzed with disbelief, Maud burned a hole through the shirt.

That book, of course, was The Wonderful Wizard of Oz.

The Man Behind the Curtain

Lyman Frank Baum was born in 1856 in Chittenango, New York. As a child, his weak heart limited his capacity for rough-and-tumble play. So, despite being the seventh of nine kids, he spent most of his childhood alone, indoors, and dreaming.

As a young man, Baum leapt like a flea from career to career. By his early 30s, he'd been a journalist, a printer, a postage-stamp dealer, and a champion poultry breeder, which led him into publishing, with his trade journal The Poultry Record. He also ran his own theater company, where he wrote, directed, and acted in his own plays.

Then, in 1881, Baum met his leading lady—Maud Gage, a sophomore at Cornell. But Maud's mother, Matilda, disapproved of the union. Matilda Gage was a feminist who marched alongside Elizabeth Cady Stanton and Susan B. Anthony in the women's suffrage movement. She saw Baum as a flake who'd never amount to anything, and she told her daughter she'd be a "darned fool" to marry the itinerant actor. Yet, Baum's charm, sincerity, and uncanny ability to tell fantastic stories were no match for Matilda, and he soon won her over. He also became a feminist.

Frank married Maud in 1882, but troubles were around the corner. Baum's theater company went belly-up, and without local prospects, he looked west for opportunity. In 1888, he moved his family to the Dakota Territory, where he opened a store in the town of Aberdeen. (Years later, when Baum wrote descriptions of the Kansas prairie in The Wonderful Wizard of Oz, he was actually describing South Dakota.) His shop, Baum's Bazaar, sold Chinese paper lanterns, Bohemian glass, gourmet chocolates, and other exotic items. But Baum overestimated the frontier's demands for novelty shopping. In a few short years, he'd gone bust yet again.

At this point, L. Frank Baum was 35 with no career. He headed east for Chicago, where he received guidance from an unexpected source: his mother-in-law. Matilda Gage convinced Baum to pursue his one true talent, telling stories. In Aberdeen, children had stalked Baum, demanding story hour from the raconteur. Kids loved his tales because they weren't thinly disguised morality lessons. Instead, Baum's stories were fantasies filled with candy, toys, magic, and adventure. Heeding Matilda's advice, Baum decided to give writing a try.

In 1899, Baum teamed up with illustrator W.W. Denslow and published Father Goose, His Book, a collection of pictures and verse. The collaboration worked so well that it inspired Baum and Denslow to try their hands at a full-length novel.

As a child, Baum had loved the European fairy tales of the Brothers Grimm, but he loathed the dark, grisly endings. He envisioned a new American fairy tale in which ingenuity and spunk paid off. In Baum's words, he wanted to create a world where "wonderment and joy are retained, and the heartache and nightmares left out."

It was a great idea, but what would he call this utopia? Family legend holds that Baum scanned his office for ideas. While staring at his filing cabinet, he drew inspiration from a label on the bottom drawer marked "O-Z."

Baum's book was turned down by every major publishing house. Finally, a distribution company agreed to take on the novel about Oz, but only if Baum and Denslow agreed to shoulder the printing expenses. The bet paid off. Today, the masterful integration of color illustrations and text is heralded as a pioneering achievement in literature, a precursor to the graphic novel. Denslow's drawings were unique in that they not only reflected the plot, but also furthered it. His vibrant pictures spilled over from one page to the next.

More importantly, children loved Baum's story. By the end of 1900, Maude had burned a hole through her husband's shirt, and The Wonderful Wizard of Oz was the best-selling book in America.

Oz Fest

Over the next 20 years, Baum would pen more than 70 books under several pseudonyms. Unfettered by gender restrictions, he often wrote under female names, including Suzanne Metcalf, Laura Bancroft, and Edith Van Dyne. Baum also tried his hand at science-fiction, demonstrating a knack for predicting the future on par with H.G. Wells. A running theme in Baum's work was the triumph of technology over distance and time, and many of his fictional inventions—televisions, satellites, cell phones, laptops—eventually became realities of everyday life.

In 1902, Oz was transformed into a Broadway musical, shortened simply to The Wizard of Oz.

At first, Baum was taken aback by some of the changes. For instance, Dorothy's faithful companion on the stage wasn't Toto, but a cow named Imogene.

But when the play became a Broadway hit, Baum softened. He tried to return to the theater to produce his own plays, but all his efforts, including The Whatnexters and The King of Gee Whiz, were flops. He also tried his hand at a vaudeville show, "Fairylogues and Radio Plays," but that foundered, too.

The truth was that Baum wanted to stop writing about Dorothy and do something new. He intended for the sixth Oz book, The Emerald City of Oz, to be the last in the series. In the story, Baum seals off his fairyland, proclaiming it unreachable from the outside world. But when a film project he was pursuing collapsed, Baum quickly found himself strapped for funds again. He wrote another Oz book, and from then on, Dorothy and the gang kept resurfacing every time Baum needed to pad his wallet.

It's a Twister

In 1919, Baum died of the same heart condition that had kept him indoors as a child. But even death couldn't stop the Oz stories from flowing. Baum wrote the 14th book in the series, Glinda of Oz, on his deathbed, and it was published posthumously. After that, various authors churned out 26 official sequels, which have been translated into 22 languages, from Tamil to Serbo-Croatian.

In 1939, the Oz legacy hit a turning point when MGM released The Wizard of Oz movie. Based on Baum's original storyline, the plot and characters remained relatively faithful to the book, although there were plenty of changes, too. Most of the quotables ("And your little dog, too!") were Hollywood additions, as were the musical numbers and dancing little people. And Dorothy's slippers, which were silver in the book, were changed to ruby in the movie to show off the new technology of color film.

The key difference between the two versions is that in the movie, Dorothy's adventure was "all a dream," while in Baum's book, Oz was very much real. In fact, later in the book series, Uncle Henry and Auntie Em move to the Emerald City to dine off jeweled plates and converse with talking animals. As it turned out, nobody really wanted to go home to Kansas.

The movie established Dorothy, the Tin Man, the Scarecrow, and the Cowardly Lion as cultural icons. Flying monkeys and yellow brick roads became part of the national psyche, and today, Oz's popularity shows no sign of waning. The movies, the spin-offs, the Broadway musicals, the plays, and—more recently—the pop-up book just keep cropping up. Much like Dorothy and the gang, Baum took the long way to finding his true calling, but there's no denying that he left behind an enduring legacy. By writing the quintessential American fairy tale, Baum proved that even late bloomers living in their own fantasy world are entitled to happy endings.

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!

Scientists Think They Know How Whales Got So Big
May 24, 2017

It can be difficult to understand how enormous the blue whale—the largest animal to ever exist—really is. The mammal can measure up to 105 feet long, have a tongue that can weigh as much as an elephant, and have a massive, golf cart–sized heart powering a 200-ton frame. But while the blue whale might currently be the Andre the Giant of the sea, it wasn’t always so imposing.

For the majority of the 30 million years that baleen whales (the blue whale is one) have occupied the Earth, the mammals usually topped off at roughly 30 feet in length. It wasn’t until about 3 million years ago that the clade of whales experienced an evolutionary growth spurt, tripling in size. And scientists haven’t had any concrete idea why, Wired reports.

A study published in the journal Proceedings of the Royal Society B might help change that. Researchers examined fossil records and studied phylogenetic models (evolutionary relationships) among baleen whales, and found some evidence that climate change may have been the catalyst for turning the large animals into behemoths.

As the ice ages wore on and oceans were receiving nutrient-rich runoff, the whales encountered an increasing number of krill—the small, shrimp-like creatures that provided a food source—resulting from upwelling waters. The more they ate, the more they grew, and their bodies adapted over time. Their mouths grew larger and their fat stores increased, helping them to fuel longer migrations to additional food-enriched areas. Today blue whales eat up to four tons of krill every day.

If climate change set the ancestors of the blue whale on the path to its enormous size today, the study invites the question of what it might do to them in the future. Changes in ocean currents or temperature could alter the amount of available nutrients to whales, cutting off their food supply. With demand for whale oil in the 1900s having already dented their numbers, scientists are hoping that further shifts in their oceanic ecosystem won’t relegate them to history.
