In 1999, Albert Einstein was awarded Time's Person of the Century. The father of special and general relativity, Einstein's theories introduced concepts that would help make dozens of modern technologies possible. "I have no special talents," Einstein was quoted saying. "I am only passionately curious." Here are some facts about the physicist who gave us crazy hair and E=MC^2.

1. When Albert Einstein was born, his misshapen head terrified the room.

On March 14, 1879, baby Einstein emerged with a "swollen, misshapen head and a grossly overweight body," according to Denis Brian's book, Einstein: A Life. When she got a look at him later, the chunky child terrified Einstein's grandmother, who screamed, "Much too fat! Much too fat!" Thankfully, Albert would eventually grow into his body. (However, he did have trouble developing in other arenas: He supposedly wouldn't start speaking until the age of 2.)

2. As a child, Einstein was the king of throwing temper tantrums.

The young genius had a habit of throwing objects whenever he was displeased; once, a frustrated Einstein even threw a chair at his teacher. The 5-year-old enjoyed bombarding his tutors and family members: His sister Maja, who was often conked in the head by Einstein's fusillades, later quipped, "It takes a sound skull to be the sister of an intellectual."

According to the biography by Alice Calaprice and Trevor Lipscombe, "When he became angry, his whole face turned yellow except for the tip of his nose, which turned white."

3. Einstein did not struggle in school.

The idea that Einstein had trouble in school is a myth. During summers, a pre-teen Einstein would study mathematics and physics for fun, eventually mastering differential and integral calculus by age 15. But that's not to say he was a perfect student. Einstein hated rote learning and refused to study subjects that didn't interest him. So, naturally, when the obstinate number-lover took the entrance exam to the polytechnic school in Zurich, he flunked the language, zoology, and botany sections.

4. Nobody knows Einstein's IQ.

Einstein's IQ was never tested, though that hasn't stopped people from guessing. Lots of websites claim the physicist's IQ was 160, but there's simply no way of verifying that claim. "One fundamental problem with the estimates I've seen is that they tend to conflate intellectual ability with domain-specific achievement," Dean Keith Simonton, professor emeritus of psychology at the University of California, Davis told Biography. For all we know, Einstein's aptitude in arenas outside of physics might have rivaled that of an average Joe.

5. Einstein refreshed his brain by playing the violin.

Whenever Einstein needed to relax, he turned to music. He started violin lessons at age 5 and, at around 17, impressed his teachers at cantonal school with his playing during a music exam. Around 1914, when Einstein lived in Berlin, he'd play sonatas with his friend and fellow theoretical physicist, Max Planck. And after he became famous, Einstein would play a handful benefit concerts alongside greats like Fritz Kreisler. "Music helps him when he is thinking about his theories," his second wife, Elsa, said. "He goes to his study, comes back, strikes a few chords on the piano, jots something down, returns to his study." [PDF]

6. Fashion was not Einstein's strong suit.

Einstein hated wearing socks and was immensely proud of the fact that he didn't have to wear them while giving lectures at Oxford in the 1930s. His antipathy apparently stemmed from a childhood realization: "When I was young I found out that the big toe always ends up making a hole in a sock," Einstein reportedly said. "So I stopped wearing socks." As an adult, he typically wore an undershirt, baggy trousers held by rope, and a pair of (occasionally women's) sandals.

7. Einstein loved sailing (and was absolutely terrible at it).

While an undergraduate in Zurich, Einstein fell in love with sailing—a passion that would persist throughout his life. There was just one problem: He was a horrible sailor. He regularly tipped his boat over and required rescue dozens of times. (His sailboat was named Tinef, Yiddish for "worthless.") In 1935, The New York Times reported on Einstein's sailing misadventures with the punny headline: "Relative Tide and Sand Bars Trap Einstein."

8. Fatherhood gave Einstein his iconic crazy hair.

As a young man, Einstein sported a well-maintained head of dark hair—that is, until his son Hans was born in 1904. Like many new parents, Einstein discovered that having a new mouth to feed changed everything: The patent clerk was so busy trying to support his family that he stopped combing his hair and visiting the barber. Slowly, an iconic look was born.

Einstein would spurn barbers for the rest of his life. His second wife, Elsa, would cut his mop whenever it became disheveled.

9. Einstein had a habit of mindlessly gorging on food.

When Einstein was a patent clerk, he formed a book club with two friends and called it the "Olympia Academy." The trio usually dined on sausages, Gruyere cheese, fruit, and tea. But on Einstein's birthday, his friends brought expensive caviar as a surprise. Einstein, who had a knack for mindlessly eating when talking about something he was passionate about, began stuffing his face while discussing Galileo's principle of inertia—totally unaware of what he was eating. He later offered this excuse: "Well if you offer gourmet foods to peasants like me, you know they won't appreciate it."

10. Einstein had a bawdy sense of humor.

Einstein enjoyed the occasional dirty joke. When he accepted his first job as a professor, he said, "[N]ow I too am an official member of the guild of whores." And when a member of his book club gave him a nameplate that said "Albert, Knight of the Backside," Einstein proudly kept it tacked on his apartment door. Later in life, he'd tell jokes to his pet parrot, Bibo. (Einstein believed the bird was depressed and needed a laugh.)

11. Einstein loved the famous tongue photo.

On his 72nd birthday, Einstein was leaving an event held in his honor. As he was getting into his car, photographers asked him to smile for the camera. Einstein, however, was sick and tired of grinning for a photograph—he'd be doing it all evening—so he popped his tongue out instead. Einstein liked the photo so much that he put it on his greeting cards.

12. Einstein was an inventor.

Having spent seven years working in the Swiss Patent Office, Einstein was naturally curious about inventing and would secure approximately 50 patents during his lifetime. He enjoyed tinkering with electronics and would eventually patent a self-adjusting camera, a refrigerator that could last 100 years, and even a blouse.

13. When it came to love, Einstein was no genius.

Einstein, who married twice, had multiple extramarital affairs—including one dalliance with a possible Russian spy. His first marriage with Mileva Marić (a physicist he met at the Swiss Polytechnic School) soured after the birth of their third child. As their marriage crumbled, Einstein imposed a list of brusque—if not cruel—demands which included: "You will obey the following points in your relations with me: 1. You will not expect intimacy from me … 2. You will stop talking to me if I request it." Unsurprisingly, they divorced. Later, Einstein married his cousin, Elsa Löwenthal.

14. A letter Einstein signed helped spark the Manhattan Project.

Einstein was not part of the Manhattan Project, but he was instrumental in getting it started. In the late 1930s, German scientists discovered nuclear fission of uranium, a major step toward the development of the atomic bomb. Much of the world's uranium was held in the Congo—then a colony of Belgium—so two Hungarian-American physicists named Leo Szilard and Eugene Wigner decided to get Einstein to write a letter to his friend, the Queen of Belgium. Einstein suggested a letter to a Belgian minister instead, but an encounter with an economist who knew President Roosevelt resulted in a change in direction and a letter that prompted America to start its own experiments.

15. Einstein loved answering fanmail from children.

Einstein received countless letters from the public, but he always tried to answer mail sent by children. (In one letter, a young girl complained about her troubles with math. The professor supposedly wrote back, "Do not worry about your difficulty in Mathematics. I can assure you mine are still greater.") Einstein's many correspondences with children—filled with charm and encouragement—are compiled in a book by Alice Calaprice called Dear Professor Einstein.

16. Einstein turned down the presidency of Israel.

After the first president of the State of Israel, Chaim Weizmann, died in 1952, the Prime Minister asked Einstein to step into the (mostly ceremonial) role. The physicist declined, writing: "I am deeply moved by the offer from our State of Israel, and at once saddened and ashamed that I cannot accept it. All my life I have dealt with objective matters, hence I lack both the natural aptitude and the experience to deal properly with people and to exercise official functions."

17. Einstein was an outspoken advocate for racial justice.

Having abandoned Germany in 1933 to avoid Nazi persecution, Einstein was sensitive of the racial discrimination he saw in the United States. He championed the rights of African Americans and was a member of the NAACP. When the famed black singer Marian Anderson came to perform at Princeton in 1937 and was denied a hotel room, Einstein invited her to stay in his home. He was also pen pals with W.E.B. Du Bois and, when Du Bois became the target of the Red Scare, Einstein effectively saved Du Bois by offering to be his character witness. In a 1946 speech he delivered at Pennsylvania's Lincoln University, he called segregation "a disease of white people," vowing, "I do not intend be quiet about it."

18. Einstein was the inspiration for Yoda.

Yoda's face was partly modeled after Einstein's. According to Star Wars special-effects artist Nick Maley, "A picture of Einstein ended up on the wall behind the Yoda sculptures and the wrinkles around Einstein's eyes somehow got worked into the Yoda design. Over the course of this evolutionary process Yoda slowly changed from a comparatively spritely [sic], tall, skinny, grasshopper kind of character into the old wise spirited gnome that we all know today."

19. Einstein's theories are more relevant than you think.

It's easy to assume that Einstein's theories of relativity are purely theoretical, but they really do affect your everyday life. For instance, the theory of general relativity states that gravity affects time: Time moves by faster for objects in space than objects here on Earth. And that has profound implications for many space-based technologies, especially the accuracy of your GPS. His theories also explain how electromagnets work and are foundational to nuclear technology.

12 Facts About Netflix, Recommended For You

Netflix has become the world’s intravenous line for filmed entertainment. And like any media empire, it has a few stories of its own to tell. Take a look at some lesser-known, non-buffering facts about the streaming giant.

1. Early Netflix subscribers got a lot of Chinese pornography.

In 1998, Netflix was still in the business of selling as well as renting DVDs. To try and offer consumers something new, co-founder Marc Randolph decided to offer footage of President Bill Clinton’s Grand Jury testimony about his involvement with Monica Lewinsky. But according to the book Netflixed, the duplicating house had a mix-up: out of the 1000 customers who ordered Clinton's interview, a few hundred received discs full of hardcore Chinese pornography.

2. Netflix was originally called Kibble.

Choosing a name for the company was a drawn-out process. Directpix.com, Replay.com, and other names were considered; so was Luna.com, which was the name of Randolph’s dog. When the company was being incorporated, he named it Kibble.com until they could decide on something permanent.

3. Netflix executives used to make house calls.

From the beginning, Netflix has been preoccupied with seeing how users interact with its software in order to select titles. In the late 1990s, subscribers near the company’s location in Los Gatos, California were reached via telephone and asked a series of questions. Then staffers would ask if they could stop by to watch them use the site. Surprisingly, most agreed. Netflix brought them coffee, a small investment for gaining valuable information about their usage.

4. Netflix got Dennis Quaid to sing.

For a 2006-2007 publicity tour, Netflix decided to screen films in thematically-correct locations: For example, Field of Dreams was shown in the “real” Iowa cornfield-slash-baseball diamond featured in the movie. But the company also wanted actors to make appearances. Their approach: offer to let those with bands perform for the crowds. Kevin Costner, Bruce Willis, Dennis Quaid, and Kevin Bacon all agreed to the barter deal. Quaid and his band, The Sharks, played in New Orleans before a screening of his film The Big Easy.

5. Netflix has made a science out of spoilers.

Because so much of Netflix’s high-profile content can be “binged” in a single weekend, the company commissioned cultural anthropologist Grant McCracken to examine how spoilers affect a person’s viewing habits. McCracken identified classifications of spoiler-prone people by whether they ruin a plot twist intentionally or hold it over others. (Some people are “Coded Spoilers,” too self-aware to let anything slip. These people are your friends.) His verdict? Some people enjoy the power they get from having knowledge of spoilers. But if a show is good enough, knowing about key scenes won't dissuade viewers from watching.

6. Netflix staffers think you decide on a movie in two minutes.

Netflix spends more than $150 million on improving their recommendation system every year, trying to arrange selections based on what they think you might like. That kind of personalized menu is necessary: The company estimates that users spend only two minutes browsing for a title before choosing one or opting for another diversion entirely.

7. Netflix staffers also think you might be kind of a liar. 

You can stop trying to impress Netflix with the streaming version of keeping Ulysses on your coffee table. In a 2013 WIRED interview, Carlos Gomez-Uribe—the company's vice president of product innovation from 2010 to 2016—noted that viewers often report viewing documentaries or esoteric foreign movies. “But in practice,” he said, “that doesn’t happen very much.”

8. the first "netflix original" was an abstract test footage short.

In order to test frame rates and how their streaming service handles different kinds of content, Netflix produced 11 minutes of test footage in 2011 that can be viewed by typing “example show” in their search engine. Cut together (as seen above), the shorts become a very strange, very abstract art film, with an unidentified man juggling and reciting Shakespeare. (But not, sadly, juggling while reciting Shakespeare.)

9. Netflix binge-watching might correlate with depression. 

A 2015 study by the University of Texas found that respondents who claimed to binge Netflix shows were more likely to suffer from depression, lack of self-control, or loneliness. The good news? The sample group was small—only 316 people—and the university’s definition of “binge-watching” was as low as two episodes. Amateurs. 

10. There’s a secret Netflix menu.

No, not that kind of secret menu. Pressing Shift + Alt + a left mouse click brings up a troubleshooting menu that allows you to adjust the bit rate of a stream so it doesn’t buffer. (On a Mac, it's Shift + Option + click.) The picture quality won’t be as good, but it’s better than a pixelated Demogorgon.

11. There was once a glitch in the Netflix matrix. 

In 2014, Netflix’s content descriptions became odd amalgamations of two different titles to create one completely nonsensical listing. The summaries were quickly fixed, but not before someone took several screen shots of the mishaps.

12. You'll soon be able to stream Netflix in a Tesla.

In July 2019, Tesla founder Elon Musk informed Tesla owners they would soon be able to stream both Netflix and YouTube in their cars, an attractive option for anyone looking to keep passengers occupied. But there's a catch: The services only work when the cars are parked. The feature will be available in newer-model cars at a date to be determined.
