The Masters is the biggest golf tournament of the year.

But let's face it, sometimes golf can be slow. As a result, the cameras tend to wander to the golfers' wives and girlfriends.

It's interesting to see how they react to their significant others' play — and they all happen to be very beautiful.

These women have gotten a ton of airtime so far, and they should get even more on Sunday.

So let's learn a little more about them.

Paulina Gretzky, Dustin Johnson's fiancee, has been the talk of the golf world recently after landing the cover of Golf Digest.

Some people didn't think she deserved the cover as much as an LPGA golfer would (we agree), but in Gretzky's defense she has done some modeling. Most recently she was in this TaylorMade commercial.

Gretzky is known for her racy Instagram feed. Here she is with Johnson and her parents, Wayne and Janet Gretzky.

CTNews.com reports that the Copper Beech mansion in Connecticut, which was once the most expensive home for sale in the U.S., has officially sold for $120 million.

The home was first listed for $190 million back in May of 2013, but the 12-bedroom mansion failed to attract a buyer. The price was chopped to $130 million in September, and after another $10 million discount, the gorgeous Connecticut property is now in contract, though there's no word yet on the buyer.

The 50-acre estate dates back to the 1890s, and was owned by timber magnate John Rudey. The property carried a reported $120 million in debt, likely accounting for the sky-high initial sale price.

The 12-bedroom home has 15,000 square feet of living space, 7,000 square feet of basement and attic space, and an 1,800-foot-long driveway. There's also a grass tennis court, innumerable gardens, apple orchard, greenhouses, 75-foot-long heated pool, and a carriage house.

The estate was listed with Christie's International Real Estate and David Ogilvy & Associates.

Earlier this week, CBS announced that Steven Colbert, of "The Colbert Report," will take over the "Late Show" when David Letterman retires in 2015.

Colbert has hosted his own political news program since 2005, adopting the unforgettable character of an idiotic, conservative political pundit. In his new gig, he will leave his fictional persona behind.

Although many fans don't know what to expect, Colbert has proved himself as a smart and hilarious guy ever since growing up the youngest of 11 children in a Southern Catholic family.

The youngest of 11 children, Stephen Colbert was born in Washington, D.C., on May 13, 1964.

Growing up in Charleston, S.C., his interest in acting was sparked by parts in several school plays.

It helped that he grew up in a home full of singing and dancing. His actress mother, Lorna, taught him how to do stage falls by pretending to faint on the kitchen floor.

On Friday, Eviction Free San Francisco, tenant rights activists and other concerned citizens gathered in the Mission District in San Francisco to protest the recent evictions of several teachers from homes in the area.

Click here to go straight to photos of the protest >>

The protesters were directly targeting Jack Halprin, who is a part of Google's legal team. Eviction Free San Francisco says that he is evicting tenants from a building he moved into, including several so-called "Ellis Act evictions." The Ellis Act is a provision in California that enables landlords to evict tenants in order to "go out of business."

Earlier in the day, many of the same protesters blocked a Google bus in the Mission District.

Johnny (no last name given), a longtime San Francisco resident and a tenant in the building who is fighting his Ellis Act eviction, said in a statement, "I don't think rich Google lawyers should be able to come into a neighborhood and buy a piece of property that is a rental property and then quickly evict everyone there to make a bigger profit. I think it's unethical."

This marks the third protest in two months that has singled out a Google employee at their home. Earlier this month, protestors targeted Google Ventures venture capitalist Kevin Rose.

We have reached out to Halprin and will update this post when we hear back. 

People gathered at Dolores Park, which is in the heart of the city's famous Mission District.

Despite the march's hilly route, people of all ages came to show support.

Many of the protesters' signs expressed anger against Google and other tech companies.

Here they are: the most important charts in the world.

We asked our favorite portfolio managers, strategists, analysts, and economists across the Street for the charts they deem the most important right now. This is what they sent us.

Much of the focus is on the amount of slack left in the labor market and the U.S. economy in general. Many are focused on the euro, too, which has surprised many observers with its persistent strength.

But there are a lot of other things going on — such as the drop in inflation expectations since the Fed began winding down quantitative easing (QE).

Enterprise cloud company Salesforce.com, and its billionaire co-founder Marc Benioff, are on top of the world right now.

He just celebrated Salesforce.com's 15-year anniversary; the company was named No. 7 on Fortune's 100 Best Companies To Work For 2014; revenues hit more than $4 billion; and it said Friday it was leasing 700,000 square feet for a new Salesforce.com Tower in San Francisco so they could hire 1,000 more employees this year.

It currently employs about 13,000 worldwide — 4,000 in the Bay Area.

Although there's some controversy about where the growth is coming from, and the $2.2 billion spent on sales and marketing instead of becoming profitable, Benioff is clearly staying in hyper-growth mode.

That growth doesn't help the tech unrest going on in San Francisco, but Benioff, a third-generation San Franciscan, has a plan for that, too. He recently launched SF Gives to raise $10 million for antipoverty programs.

With its workforce scattered among buildings in San Francisco, Salesforce.com calls itself an "urban campus."

Salesforce occupies a handful of buildings in San Francisco in an "urban campus." 50 Fremont St. isn't the official headquarters but it is one big hub. The lobby is modern but that's misleading ...

Salesforce.com's style is louder, brighter and Hawaiian, like this mural on elevator-hall ceilings. Co-founder Marc Benioff owns a huge compound in Hawaii and signs his annual letter "Aloha."

Inside there's still plenty of artwork, like this ornate piece near a staircase in the human resources department.

Some species of viruses, fungi, protozoans, wasps, and tapeworms take over the brains and actions of the animals and insects they infect — making them do whatever their new master wants.

A recent issue of the Journal of Experimental Biology was completely dedicated to these parasites, which turn their hosts into zombies.

This is usually controlled by special biochemistry. The parasites release chemicals or manipulate the genes of their host, changing their behaviors. Most them them do this by changing the brain's chemicals, or by inducing "sickness behaviors" by messing with the host's immune system.

"The fact that parasites can so efficiently alter host behavior is fascinating," guest editor of the journal, Michael Dickinson, from the University of Washington, said in an article in the issue. "There is something horrifying and wondrous about a tiny 'implant' being able to control such a large animal machine."

Hymenoepimecis argyraphaga – These wasps live in the spider Plesiometa argyra. The wasp injects chemicals into the spider that make it abandon its web and build a completely different one, with a thick sheet to protect the wasp's offspring's cocoons, which they build after chewing through the spider's body.

Baculovirus – This virus infects Gypsy moth caterpillars and releases an enzyme that stops their natural molting cycle, makes them eat continually, and forces them to climb to the top of trees and clamp onto the leaves until it dies and liquefies, raining down viruses across the forest to infect other caterpillars.

Toxoplasma gondii – Picked up from cat poop, this tiny (one-celled) parasite infects the brains of rats, causing them to make extra dopamine and testosterone, which makes them fearless. When they aren't afraid of cat smells, they venture out into the animals' presence, and get eaten, spreading the parasite to the cat. They also mate more, spreading the parasite to other rats.

When the world's top automakers need a design that's capable of captivating the public's imagination, they turn to the master craftsmen at boutique design firms. 

Over the last 100 years, few firms have penned more memorable and striking designs than Gruppo Bertone. 

Sadly, the famed Italian design firm behind some of the most iconic cars in automotive history, has confirmed it has entered bankruptcy proceedings.

According to BBC's Top Gear, mounting debt forced the firm to shutter its operations last month and send its 120 employees home. 

"The problem is many debts and very high costs. At the moment everything is blocked,"a company spokesperson told the Telegraph. "People haven't been coming to work for a month and a half now."

The fate of the famed design house, known for its adventurous and avant garde concepts, should be clear by the end of April when the court will either announce a buyout deal or the liquidation of its assets.

This isn't the troubled firm's first brush with financial peril. Bertone faced similar financial troubles in 2007, 2008, and 2011.

It was able to stave off collapse by selling off its prized manufacturing assets and famed design prototypes. But stripped of its most valuable assets, Bertone does not seem to have the stamina to withstand another barrage of creditors.

As Bertone once again teeters on the brink of collapse, here's a look back at some of its greatest artistic contributions to automotive history.

In the supercar gospel, the Lamborghini Miura is Genesis. The Miura, which catapulted designer Marcello Gandini to stardom at the 1966 Geneva Motor Show, is credited with pioneering the mid-engine form that's since become synonymous with supercars.

The 1974 Lamborghini Countach and its iconic upward-hinged doors became the go-to bedroom poster for a whole generation of teenage boys. If the Miura is the car that made Gandini a star, then the Countach is the car that made him immortal.

The futuristic Alfa Romeo Pandion Concept debuted at the 2010 Geneva Auto Show, to celebrate Alfa's 100th anniversary. The Pandion features Bertone's signature upward-hinged doors.

Before the Pebble blew past its Kickstarter goal; before the iWatch was a twinkle in anyone's eye; there was the Casio calculator watch. And it was awesome.

The Casio calculator watch is still awesome. And that's why I just bought one on Amazon for $15.

I never had a calculator watch when I was a kid — the closest thing to a "smart watch" I had was a Game & Watch that played a "Popeye" game — and the one that I have now is hardly as cool as some of the ones from 30 years ago, although it's still pretty cool.

But the calculator watch phenomenon actually started way before Casio became synonymous with this type of timepiece. In fact the first Casio calculator watch came out almost five years after the first calculator watches hit store shelves.

There are debates about which calculator watch actually came first. Some say it was the Calcron LED Wrist Calculator, which was advertised in the "dads and grads" section of a 1975 Playboy magazine. But others say it was the Pulsar, formerly the Hamilton Watch Company, that was the first.

Pulsar calculator watch

The Pulsar calculator watches hit the scene in 1975. They were 18-karat gold and sold for $3,950 (!) at high-end jewelry stores, like Tiffany. (You can buy one now on eBay for a whopping $27,500.)

The watch came with a tiny stylus so you could press the small buttons for the calculator. The battery lasted only a couple of weeks — the watch displayed information when you pressed a button or flicked your wrist, depending on the model, to save battery — and it was heavy and slightly uncomfortable to wear.

In 1976, the company came out with a less-expensive version in stainless steel ($550); a year later it had a 14-karat-gold-filled model for $495, and the stainless steel version dropped to $395.

Hewlett-Pakcard HP-01 calculator watch

In 1977, Hewlett-Packard threw its hat into the ring with its own LED calculator watch, the HP-01. There were five models, and prices ranged from $650 to $850. It was smarter than most pocket calculators at the time, and could perform more than three dozen functions. And according to HP, "when HP discontinued manufacturing the HP-01, its inner workings were destroyed so no one would copy the extraordinarily small package engineering."

But competition was getting fierce, as LED was soon being replaced by more energy efficient LCD displays.

And that's where Casio came in.

Casio C-80

Casio's calculator watches weren't the first of their kind, but Casio did offer the biggest variety of models. The company's first calculator watch was the C-80, which had buttons large enough that you didn't need to use a stylus.

The other great thing about it: It only cost around $50.

And this was just the beginning. That same year, Casio released a touchscreen calculator watch, the TC-50, for around $50, and the CM-32, which did metric conversions. In 1983 it released the CD-40, which was one of the first of a slew of watches — called Data Bank — that allowed you to store actual information, like phone numbers.

Casio CA-53W

Which brings me back to the CA-53W that I just bought on Amazon. Since it's tax season, I've actually used it quite a bit. It's basic — it doesn't even have a light — but it brings back a wave of nostalgia when I look down at my wrist. Now I can be like Marty McFly from "Back to the Future," just like I always wanted to be.

More and more people are equipping their houses with high-tech automation systems, but it's not likely you'll find a smart home as beautiful as this one. 

This five-bedroom house is located on a hilltop in Studio City, Calif., a neighborhood just outside Los Angeles in the San Fernando Valley. The home is visually stunning, but the technology inside is equally impressive. 

The house is divided into zones where temperature and audio can be controlled via wall units. All of the lights in the house can be turned off with just the touch of a button, while disappearing glass walls make for the ultimate indoor-outdoor experience.

It can be rented on HomeAway for $2,995 a night. 

This smart home is perched on the top of a hill overlooking Southern California's San Fernando Valley.

It's extremely private, and each guest is given a pre-programmed custom code that gives them keyless entry to the house's gate, garage, and front door.

Inside, the decor is impossibly chic.

This Sunday marks the beginning of the end for Madison Avenue's most famous ad agency, as the first half of the final 7th season of "Mad Men" premieres on AMC.

But before we begin to say goodbye, here's a refresher of everything you need to know before returning to Sterling Cooper.

Warning: spoilers ahead.

When we last left Don Draper (Jon Hamm) he was still married to his young actress wife, Megan (Jessica Paré).

But he was having an affair with his married neighbor, Sylvia (Linda Cardellini).

The affair goes on until Don's daughter Sally (Kiernan Shipka) catches him in the act.

Decades after the era when the Ku Klux Klan lynched African-Americans, the hate group is still fighting for white power.

There are active chapters in 41 U.S. states, with between 5,000 and 8,000 active members, according to the Southern Poverty Law Center. Members are split among local organizations like the Fraternal White Knights of the Ku Klux Klan in Tennessee and a few national organizations, like the Knights of the Ku Klux Klan.

Photojournalist Anthony S. Karen has spent the last eight years documenting Klan organizations in 14 states across the country. We've published some of his photos below; more can be found in an eBook on iTunes called “White Pride.”Karen says that when he works, he strives to be a nonjudgmental observer who accepts each person as an individual. This attitude helped him get incredible access to notoriously wary subjects.Karen started his project by contacting a number of local KKK groups via contact information on their websites. Most said no, but one eventually agreed to let him photograph a cross-lighting ceremony if he left his camera in the car until the ceremony began. 

Cross-lightings are most often associated with attempts by the Klan to intimidate or threaten minority members of its community, though Klan members claim it is meant to symbolize the members' faith in Christ. Some current Klan organizations attempt to distance themselves from cross-lightings meant to intimidate people, which they call "cross-burnings."After the first event, Karen met with the leader of one of the largest Klan organizations, who extended an open invitation for Karen to attend any events that he hosted. The acceptance from the Klan leader led other organizations to take him seriously and invite him to other gatherings. This photo is a Klan gathering in North Carolina.

The Klan also invited him to a lot of casual gatherings, including meetings known as Klonvocations, "unity" barbecues, and even a traditional Klan wedding, held at a Civil War battleground site. Here, an Imperial Wizard and his wife grocery shop before a spring "unity" barbecue.

Klan members were mostly guarded when Karen first met them, so he left his camera at his side for most of the first rally he attended and later only photographed people with their permission.

"Once your subject feels that you respect them as a person, they tend to forget about the camera altogether and the intimacy will occur naturally," Karen told Business Insider.

Karen says that the overall impression he got was that today's Klan members often join because they want to be part of an exclusively white organization that opposes homosexuality, interracial relationships, and illegal immigration.

The largest Klan organization is called Knights of the Ku Klux Klan, which is also known as the Knight's Party, and it's based in Harrison, Ark. Here's the national director of the Knight's Party, Thomas Robb (center), along with some of his family members.

Each year, the Knight's Party holds an annual congress, called the Faith and Freedom Conference. It is usually held outside of Harrison on a Klan member's property. Most attendees come with their whole families, and some camp outside the conference compound for the weekend. Here are Klan members on a break from that conference.

Karen says that, for the most part, members try to avoid confrontation, though it happens most often during public events.

One confrontation that Karen witnessed followed a rally hosted by the Mississippi White Knights of the Ku Klux Klan at the Lee County Courthouse in Tupelo, Miss. The protest was against illegal immigration and local sex offenders. Klan members were also protesting for schools to reinstate mandatory prayers.

It was the first major Klan appearance in Tupelo since the 1970s.

With a life as storied as he had, it's no wonder that Steve Jobs is remembered not only for running an incredibly successful company, but for being tremendously outspoken.

He seemingly had an opinion on everything, and his thoughts often echoed his obsessive commitment to quality at Apple, whether on his approach to mistakes ("Sometimes when you innovate, you make mistakes. It is best to admit them quickly, and get on with improving your other innovations.") or his attention to detail ("Design is not what it looks and feels like. Design is how it works.").

But he had plenty to say on deeper matters as well. Here's a roundup of some of his more thought-provoking words collected from various interviews and speeches.

"Creativity is just connecting things. When you ask creative people how they did something, they feel a little guilty because they didn’t really do it, they just saw something. It seemed obvious to them after a while."

"Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart."

"If you haven’t found it yet, keep looking. Don’t settle. As with all matters of the heart, you’ll know when you find it. And like any great relationship, it just gets better and better as the years roll on."

University of California, San Diego — Geisel Library

UCSD's main library is named in honor of Audrey and Theodor Seuss Geisel — better known as Dr. Seuss — who donated to the library throughout their lifetimes.

The Geisels were long-time residents of La Jolla, the San Diego, California neighborhood that includes UCSD.

Soon, China will begin limiting how many tourists can visit the Forbidden City in Beijing. 

The former Imperial Palace sees about 7 million visitors each year, and officials think that's just too many people.

Worried about inflicting damage to the important historical site, China's state media recently announced that it will begin limiting how many tourists it admits to the Forbidden City. 

The new limitations will prohibit annual ticket holders from visiting during peak seasons, encourage tourists to visit in the afternoon and to buy tickets in advance during festivals and holidays.

Take a look around the UNESCO World Heritage Site — while you still can.

Originally built in the early 1400s, the Forbidden City served as the imperial palace for Chinese emperors and their families for almost 500 years.

It was closed off to visitors for hundreds of years. Only the emperor, his immediate family, officials, and servants could access the complex — hence the name, "Forbidden City."

But today it's one of the most popular tourist sites in China, with about 7 million visitors each year.

Istanbul, Turkey, was just ranked the most popular travel destination in the world by TripAdvisor.

Millions of TripAdvisor users voted on their favorite destinations around the world, and Istanbul took the top spot. This is surprising because the city jumped 11 spots from the previous year, surpassing perennial favorites like London and Rome.

So why are travelers flocking to Istanbul? Perhaps it's because the vibrant city embodies both ancient and modern. It's chock-full of historic mosques and monuments, but it also has tons of hip boutiques, cool restaurants, and design-savvy boutique hotels that hipsters, foodies, artists and fashionistas love. The city feels decidedly chic — and travelers from all over the world are taking note.

Located in a former warehouse on the Bosphorus, the Istanbul Modern showcases cutting-edge contemporary art from Turkish artists.

The restaurant at the Istanbul Modern serves international cuisine in a sleek design-conscious setting.

Nearby, the neighborhood of Cihangir is quickly becoming one of the coolest areas in Istanbul, attracting hipsters and artists with its Bohemian chic vibe and its cafes, shops and galleries.

Music has always been one of the most important aspects of AMC's "Mad Men."

Which is why, when creator Matthew Weiner wanted to use a Beatles song in season 5's "Lady Lazarus" episode, he refused to settle for anything but the real deal.

Instead of using a cover of the band's "Tomorrow Never Knows," Weiner insisted they use a master recording that cost the production upward of $250,000.

As we head into the Season 7 (Part 1) premiere this Sunday, here's the behind-the-scenes story of how one pricey "Mad Men" episode came to be.

"The Band of the 20th Century"

From the real-life ad campaigns to the fashions, most everything on "Mad Men" is authentically 1960s. But for Weiner, there was always one glaring inauthenticity on the show.

“It was always my feeling that the show lacked a certain authenticity because we never could have an actual master recording of the Beatles performing," Weiner told The New York Times. "It always felt to me like a flaw. Because they are the band, probably, of the 20th century.”

That isn't to say that the series has never sampled from the band's catalogue. In season 4 episode "Hands and Knees," Beatles song "Do You Want to Know a Secret" played over the credits. However, it was an instrumental cover which only requires the more affordable publishing rights.

The difference between publishing rights and master rights is that while the publishing rights are controlled by the publisher working for the songwriter or composer, master recordings are owned by record labels. Labels get to set the price for how the song is being used and how popular they think it is.

Acquiring the rights to any music can be costly enough, but gaining the rights to a Beatles recording is extremely expensive and difficult — a fact that Weiner and "Mad Men" would soon come to realize.

Don Draper's $250,000 Beatles Record

For television, the Beatles had always been the "holy grail" when it came to licensing.

This meant that "Mad Men" had an up-hill battle, but it helped that the remaining members of the band are fans of the show.

"In the case of the Beatles, they're not known for opening up their song catalogue to everyone," show writer Andre Jacquemetton told the Canadian Press. "It just turns out actually that they're huge fans of the show.

According to The Wall Street Journal, it's common to hear Beatles covers, but not the actual Beatles songs. When it does happen, it typically "involves fees of over $1 million." Such was the case with 2010's "Dinner For Schmucks," which used "Fool on the Hill" for a reported $1.5 million.

In contrast, most other popular songs that are licensed for TV shows can be purchased for under $100,000.

Ultimately, Lionsgate — the studio behind "Man Men"— paid $250,000, and used the song for less than 2 minutes in season 5's "Lady Lazarus," as Don Draper tried to stay in tune with '60s youth culture, but was ultimately left unimpressed.

Watch the $250,000 scene below:

The Beatles and "The End" of "Mad Men"

"Mad Men's" use of "Tomorrow Never Knows" was the first time a TV show had used a Beatles master track, and with that distinction came a price that was about five times the average rate.

Yet, even though the costs were high, this may not be the last time "Mad Men" uses the Fab Four's catalogue.

As we head into the series' final season, the music of Paul, John, George, and Ringo may play into Weiner's end-game for the entire series, as he told Grantland:

"I want to leave the show in a place where you have an idea of what it meant and how it’s related to you. It’s a very tall order, but I always talk about 'Abbey Road. What’s the song at the end of 'Abbey Road'? It’s called ‘The End.’ There is a culmination of an experience of people working at their highest level."
