Necessity isn't the only mother of invention. Though it wasn't always easy to get patents or the credit they deserved, women are responsible for many items we use today.

1. THE PAPER BAG

America got a brand new paper bag when cotton mill worker Margaret Knight invented a machine to make them with a flat square bottom in 1868. (Paper bags originally looked more like envelopes.) A man named Charles Annan saw her design and tried to patent the idea first. Knight filed a lawsuit and won the patent fair and square in 1871.

2. KEVLAR

Lightweight, high-tensile Kevlar—five times stronger than steel—will take a bullet for you. DuPont chemist Stephanie Kwolek accidentally invented it while trying to perfect a lighter fiber for car tires and earned a patent in 1966.

3. THE FOOT-PEDAL TRASH CAN

Lillian Gilbreth improved existing inventions with small, but ingenious, tweaks. In the early 1900s, she designed the shelves inside refrigerator doors, made the can opener easier to use, and tidied up cleaning with a foot pedal trash can. Gilbreth is most famous for her pioneering work in efficiency management and ergonomics with her husband, Frank. Two of their 12 children, Frank Jr. and Ernestine Gilbreth, humorously wrote about their home/work collaborations in the book Cheaper by the Dozen.

4. MONOPOLY

Elizabeth Magie created The Landlord's Game to spread the economic theory of Georgism—teaching players about the unfairness of land-grabbing, the disadvantages of renting, and the need for a single land value tax on owners. Fun stuff! Magie patented the board game in 1904 and self-published it in 1906. Nearly 30 years later, a man named Charles Darrow rejiggered the board design and message and sold it to Parker Brothers as Monopoly. The company bought Magie's patent for the original game for $500 and no royalties.

5. WINDSHIELD WIPERS

Drivers were skeptical when Mary Anderson invented the first manual windshield wipers in 1903. They thought it was safer to drive with rain and snow obscuring the road than to pull a lever to clear it. (Another woman inventor, Charlotte Bridgwood, invented an automatic version with an electric roller in 1917. It didn't take off, either.) But by the time Anderson's patent expired in 1920, windshield wipers were cleaning up. Cadillac was the first to include them in every car model, and other companies soon followed.

6. DISPOSABLE DIAPERS

Marion Donovan didn't take all the mess out of diaper changing when she patented the waterproof "Boater" in 1951. But she changed parenting—and well, babies—forever. The waterproof diaper cover, originally made with a shower curtain, was first sold at Saks Fifth Avenue. Donovan sold the patent to the Keko Corporation for $1 million and then created an entirely disposable model a few years later. Pampers was born in 1961.

7. THE DISHWASHER

Patented in 1886, the first dishwasher combined high water pressure, a wheel, a boiler, and a wire rack like the ones still used for dish drying. Inventor Josephine Cochrane never used it herself, but it made life easier for her servants.

8. LIQUID PAPER

In the days before the delete key, secretary Bette Nesmith Graham secretly used white tempera paint to cover up her typing errors. She spent years perfecting the formula in her kitchen before patenting Liquid Paper in 1958. Gillette bought her company in 1979 for $47.5 million. And that's no typo.

9. ALPHABET BLOCKS

Children don't read books by anti-suffrage author Adeline D.T. Whitney these days—and that's probably for the better. But the wooden blocks she patented in 1882 still help them learn their ABCs.

10. THE APGAR SCORE

Life is a series of tests, starting with the Apgar, named after obstetrical anesthesiologist Dr. Virginia Apgar. In 1952, she began testing newborns one minute and five minutes after birth to determine if they needed immediate care. About 10 years later, the medical community made a backronym—an acronym designed to fit an existing word—to remember the criteria scored: Appearance, Pulse, Grimace, Activity, and Respiration.

11. MARINE SIGNAL FLARES

Communication between ships was once limited to colored flags, lanterns, and screaming things like "Thar she blows!" really loudly. Martha Coston didn't come up with the idea for signal flares all by herself. She found plans in a notebook that belonged to her late husband. The determined widow spent 10 years working with chemists and pyrotechnics experts to make the idea a reality. But she was only named administratrix in the 1859 patent—Mr. Coston got credited as the inventor.

12. THE CIRCULAR SAW

A weaver named Tabitha Babbitt was the first to suggest that lumber workers use a circular saw instead of the two-man pit saw that only cut when pulled forward. She made a prototype and attached it to her spinning wheel in 1813. Babbitt's Shaker community didn't approve of filing a patent, but they took full advantage of the invention.

13. RETRACTABLE DOG LEASH

New York City dog owner Mary A. Delaney patented the first retractable leading device in 1908. It attached to the collar, keeping pooches under control, while giving them some freedom to roam. Incidentally, someone named R.C. O'Connor patented the first child harness 11 years later. Coincidence? Maybe.

14. SUBMARINE TELESCOPE AND LAMP

It's difficult to find any in-depth information about early inventor Sarah Mather. Her combination telescope and lamp for submarines, patented in 1845, speaks for itself.

15. FOLDING CABINET BED

Sarah E. Goode's folding cabinet bed didn't just maximize space in small homes. In 1885, it made her the first African-American woman with a U.S. patent. The fully functional desk could be used by day and then folded down for a good night's sleep. The Murphy bed came along some 15 years later.

16. THE SOLAR HOUSE

Biophysicist Maria Telkes's place was in the house—the very first 100 percent solar house. In 1947, the Hungarian scientist invented the thermoelectric power generator to provide heat for Dover House, a wedge-shaped structure she conceived with architect Eleanor Raymond. Telkes used Glauber's salt, the sodium salt of sulfuric acid, to store heat in preparation for sunless days. Dover House survived nearly three Massachusetts winters before the system failed.

17. SCOTCHGARD

Apparently, it takes a stain to fight one. In 1952, 3M chemist Patsy Sherman was perplexed when some fluorochemical rubber spilled on a lab assistant's shoe and wouldn't come off. Without changing the color of the shoe, the stain repelled water, oil, and other liquids. Sherman and her co-inventor Samuel Smith called it Scotchgard. And the rest is ... preserving your couch.

18. INVISIBLE GLASS

Katharine Blodgett, General Electric's first female scientist, discovered a way to transfer thin monomolecular coatings to glass and metals in 1935. The result: glass that eliminated glare and distortion, which revolutionized cameras, microscopes, eyeglasses, and more.

19. COMPUTERS

Women in computer science have a role model in Grace Hopper. She and Howard Aiken designed Harvard's Mark I computer, a five-ton, room-sized machine in 1944. Hopper invented the compiler that translated written language into computer code and coined the terms "bug" and "debugging" when she had to remove moths from the device. In 1959, Hopper was part of the team that developed COBOL, one of the first modern programming languages.

10 Game of Thrones Fan Theories About How the Series Will End

HBO
HBO

Our faces are longer than Jon Snow’s right now. It’s been nearly a year since the last season of Game of Thrones ended, but season 8—the series's final one—won’t air until next spring. To tide you over until 2019, we’ve collected some of the most plausible as well as the most bonkers fan theories about what could go down in the final episodes. They predict everything from a new contender for the Iron Throne to a new species classification for a major character. On the bright side, we’ll all have plenty of time to debate these before the first episode airs.

1. JON SNOW WILL KILL DAENERYS.

Almost since the series began, fans have been predicting that Jon Snow is the Prince Who Was Promised—a reincarnation of the legendary hero Azor Ahai. But most predictions have overlooked a central piece of the Azor Ahai legend, which may spell doom for Daenerys: Azor Ahai, a lousy metallurgist, had a tough time forging his fabled flaming sword Lightbringer. Then he realized he needed to temper the blade by plunging it into the heart of his wife, Nissa Nissa, to imbue it with her power. (Because in the logic of this legend, killing a powerful woman turns a mediocre man into a hero.) If Jon Snow is Azor Ahai, the theory goes, then Daenerys will be his Nissa Nissa—the one true love he must kill in order to save the realm.

2. THE LANNISTERS’ REPAID DEBTS WILL BE THEIR DOWNFALL.

You know the family creed: A Lannister always pays his debts. In Season 7, Cersei stayed true to her family name when she paid off a large debt to the Iron Bank. Most viewers read this as a play to buy the loyalty of the bank and its mercenary soldiers, but one Machiavellian Redditor has predicted that paying off the debt will have the opposite effect. “While the Lannisters were in debt to the Bank, the Bank had a vested interest in their success,” one Redditor wrote. Now that the debt is paid, the Iron Bank will invest in the side that seems to have the best chance of winning—and right now, that doesn’t look like Cersei's.

3. EURON GREYJOY IS THE FATHER OF CERSEI’S CHILD.

Somehow this seems more disturbing than Jamie being the baby’s incestuous father. PopSugar rolled out this hot take based on some circumstantial evidence. First, Euron and Cersei cooked up a plan to betray Jon and Daenerys without telling Jamie, which “raises the question about what else Cersei was doing with Euron behind Jamie’s back.” Then there’s the fact that Cersei just let Jamie ride north to fight the White Walkers, which doesn’t seem like a risk you’d want your unborn child’s father to take. She has no idea when or if he’ll be back. But on the other hand, she knows exactly where Euron will be. Perhaps she’s keeping an eye on her baby’s true father.

4. DAENERYS WILL DIE BEYOND THE WALL.

Redditor Try_Another_NO reached all the way back to season 2 to substantiate this theory about Daenerys’s demise. While Daenerys is in the House of the Undying, she has a series of possibly prophetic visions. She walks through the throne room in Kings Landing, which is damaged and filled with snow. Before she can touch the Iron Throne, she’s called away by a sound and suddenly finds herself walking beyond the wall. There she meets Khal Drogo who says he has resisted death to wait for her. According to the theory, these were clues about the series’s end: The White Walkers will threaten Kings Landing. Daenerys will turn away from the throne to fight the White Walkers. Death awaits her beyond the wall.

5. CLEGANEBOWL WILL FINALLY HAPPEN.

For years fans have eagerly awaited a fight between Sandor and Gregor Clegane, which has been affectionately dubbed “Cleganebowl.” In the season 7 finale, the Hound hinted that the much-hyped fight is coming when he told his brother, “You know who's coming for you.” The cryptic message also spawned a fan theory about the real origin of the Clegane brothers’ beef. Our only version of the tale comes from noted liar/sleazebag Littlefinger, who claimed Ser Gregor burned his brother’s face over a stolen toy. But Redditor 440k11 thinks the Hound has always had a talent for reading the future in the flames. In fact, the theory goes, the Hound saw his brother’s death foretold in a fire and told him about it. Enraged, young Gregor pushed his brother’s face into the fire he was reading, burning Sandor and cementing their lifelong enmity.

6. VARYS IS ACTUALLY A MERMAN.

The case for this one is watertight. The books make several mentions of merlings living alongside dragons, giants, and White Walkers—mythical creatures we know exist in Essos. Varys, meanwhile, constantly covers his lower body in long robes. What is he hiding? According to Redditor nightflyer, it’s his freaky fish body. In the books, it would explain his cryptic response when Tyrion threatened to have him thrown off a ship: “You might be disappointed by the result.” In the show, it might explain how Varys traveled from Dorne to Daenerys's ship in Mereen seemingly overnight in the middle of season 7. (It wasn’t lazy writing—he swam there!) In general, it might explain why he’s such a slimy weirdo.

7. THE MAESTERS ARE COLLUDING WITH CERSEI TO BEAT DAENERYS.

Finally, a fan theory fit for our political age! According to this theory, the maesters are natural enemies of magic. The strange forces that bring the dead back to life, reveal the future in fire, and allow Arya to wear many faces are beyond the maesters’ powers of rational explanation. But if magic were eliminated, the maesters’ monopoly on knowledge would continue unchallenged. It follows, then, that the maesters would feel comfortable with Cersei’s cruel reign but threatened by Daenerys’s magical dragons. Maybe that explains why a former maester built Cersei a weapon meant to kill dragons. And maybe the maesters will intervene in the conflict more directly in the next season.

8. ARYA WILL KILL CERSEI ... WEARING JAMIE’S FACE.

Predicting that Jamie will kill Cersei is so mainstream. Seeing Jamie kill Cersei for the good of the realm would reprise his role as the Kingslayer (or Queenslayer). It would neatly fulfill the Volanqar prophecy—the prediction a witch made to a young Cersei, that she would be killed by a volanqar (which translates to "younger sibling" in High Valyrean). And it would be so easy. Reasoning that George RR Martin would never do something so obvious, and that Arya’s assassin character arc has to led to a more consequential target than Walder Frey, Redditor greypiano predicts that Arya will be Cersei’s killer. If she first kills Jamie and uses his face to catch Cersei unaware, then the volanqar prophecy will be confirmed (even if it’s on a technicality).

9. VISERION WILL COME BACK TO LIFE.

Here’s a fan theory for moms, from a mom. Redditor Cornholio_the_white wrote that after the season 7 finale, their mom called to say she was sad about Viserion’s death. But she had a prediction: “I think it’s going to remember its mother.” She explained that Daenerys’s love would free Viserion from the Night King’s spell. Cornholio_the_white scoffed. That wasn’t possible. The dragon was dead. But then Mom dropped a compelling counterargument: “Not if the Red Woman brings it back. They’re keeping her around for something.”

10. GENDRY IS THE LEGITIMATE CHILD OF CERSEI AND ROBERT BARATHEAN.

This theory throws another contender for the Iron Throne into the mix. It maintains that Gendry was not Robert Barathean’s bastard son—in fact, he was the only legitimate child of the king. We know that Cersei and Robert had a child—a “black-haired beauty”—who supposedly died shortly after birth. Curiously, Cersei says she never visited her firstborn child in the crypt, even though we know she is a fiercely devoted mother. Perhaps that’s because she knew her son was actually in Fleabottom as a blacksmith’s apprentice. And perhaps it was Cersei all along who was looking out for Gendry, securing his apprenticeship and protecting him from Joffrey’s purge of Robert’s bastards. Gendry, for his part, remembers only that his mother had yellow hair. If that yellow-haired woman was Cersei, Gendry would have the most legitimate claim to the Iron Throne of anyone in Westeros.

10 Things You Might Not Know About Steve Martin

Is there anything Steve Martin can't do? In addition to being one of the world's most beloved comedians and actors, he's also a writer, a musician, a magician, and an art enthusiast. To celebrate his birthday (he turns 73 today), here are 10 things you might not have known about Steve Martin.

1. HE WAS A CHEERLEADER.

As a yellleader (as he refers to it in a yearbook signature) at his high school in Garden Grove, California, Martin tried to make up his own cheers, but “Die, you gravy-sucking pigs,” he later told Newsweek, did not go over so well.

2. HIS FIRST JOB WAS AT DISNEYLAND.

Martin’s first-ever job was at Disneyland, which was located just two miles away from his house. He started out selling guidebooks, keeping $.02 for every book he sold. He graduated to the Magic Shop on Main Street, where he got his first taste of the gags that would later make his career. He also learned the rope tricks you see in ¡Three Amigos! from a rope wrangler over in Frontierland.

3. HE OWES HIS WRITING JOB WITH THE SMOTHERS BROTHERS TO AN EX-GIRLFRIEND.

Thanks to a girlfriend who got a job dancing on The Smothers Brothers Comedy Hour, Martin landed a gig writing for the show. He had absolutely no experience as a writer at the time. He shared an office with Bob Einstein—better known to some as Super Dave Osborne or Marty Funkhauser—and won an Emmy for writing in 1969.

4. HE WAS A CONTESTANT ON THE DATING GAME.

While he was writing for the Smothers Brothers, but before he was famous in his own right, Martin was on an episode of The Dating Game. (Spoiler alert: He wins. But did you have any doubt?)

5. MANY PEOPLE THOUGHT HE WAS A SERIES REGULAR ON SATURDAY NIGHT LIVE.

Martin hosted and did guest spots on Saturday Night Live so often in the 1970s and '80s that many people thought he was a series regular. He wasn't. 

6. HIS FATHER WROTE A REVIEW OF HIS FIRST SNL APPEARANCE.

After his first appearance on SNL, Martin’s father, the president of the Newport Beach Association of Realtors, wrote a review of his son’s performance in the company newsletter. “His performance did nothing to further his career,” the elder Martin wrote. He also once told a newspaper, “I think Saturday Night Live is the most horrible thing on television.”

7. HE POPULARIZED THE AIR QUOTE.

If you find yourself making air quotes with your fingers more than you’d really like, you have Martin to thank. He popularized the gesture during his guest spots on SNL and stand-up performances.

8. HE QUIT STAND-UP COMEDY IN THE EARLY 1980S.

Martin gave up stand-up comedy in 1981. “I still had a few obligations left but I knew that I could not continue,” he told NPR in 2009. “But I guess I could have continued if I had nothing to go to, but I did have something to go to, which was movies. And you know, the act had become so known that in order to go back, I would have had to create an entirely new show, and I wasn't up to it, especially when the opportunity for movies and writing movies came around.”

9. HE'S A MAJOR ART COLLECTOR.

As an avid art collector, Martin owns works by Pablo Picasso, Roy Lichtenstein, David Hockney, and Edward Hopper. He sold a Hopper for $26.9 million in 2006. Unfortunately, being rich and famous doesn’t mean Martin is immune to scams: In 2004, he spent about $850,000 on a piece believed to be by German-Dutch modernist painter Heinrich Campendonk. When Martin tried to sell the piece, “Landschaft mit Pferden” (or "Landscape With Horses") 15 months later, he was informed that it was a forgery. Though the painting still sold, it was at a huge loss.

10. HE'S AN ACCOMPLISHED BLUEGRASS PERFORMER.

Many people already know this, but we’d be remiss if we didn’t mention that he’s an extremely accomplished bluegrass performer. With the help of high school friend John McEuen, who later became a member of the Nitty Gritty Dirt Band, Martin taught himself to play the banjo when he was 17. He's been picking away ever since. If you see him on stage these days, he’s likely strumming a banjo with his band, the Steep Canyon Rangers. As seen above, they make delightful videos.
