Nearly all great inventions come from the need to solve a problem. And the creation of one of the world's first men's modern wristwatches in 1904 was no different.

This invention was born when Louis Cartier, one of three grandsons of Cartier's founder, befriended the Brazilian aviator and adventurer Alberto Santos-Dumont.

Santos-Dumont is regarded by many to be the first man to successfully pilot a flight. He is so beloved by Brazilians that they even paid tribute to him at this year's Olympic opening ceremony in Rio de Janeiro.

At the beginning of his aviation career, Santos-Dumont had a predicament: As a pilot, he was not able to easily pull out his pocket watch mid-flight to tell the time because his hands were clearly needed on the plane's controls of the open cockpit. To solve his friend's problem, Louis Cartier set out to develop Cartier's first modern wristwatch.

Now known as the Santos de Cartier, the creation parted with convention in many ways. Until then, most men's watches were placed on a chain and stored in a pocket or worn as a brooch.

The new wristwatch design enabled Santos-Dumont to tell the time with minimal movement.

It also stood out for its industrial style because it was mounted on leather — an unheard-of material for watchmakers at the time. Most watches were embellished with precious metals and stones, like pearls and onyx, to complement motifs seen in fine-jewelry collections.

A timeless design

Hinting at the art deco movement that was to come, the Santos de Cartier was geometric in design featuring an extra-large bezel, a rounded dial, and curved lugs leading to the strap.

Most interestingly, it exposed what most watchmakers hid: screws. The look of the watch was an ode to modern machinery, and the screws echoed the rivets on the body of an aircraft — another nod to Santos-Dumont.

This was meant to be a man's watch. The style suggested its wearer should be an avid adventurer, explorer, and early supporter of technological progress.

Even today, Cartier describes this first watch as modern yet timeless: a perfect balance of form and function. The original Santos de Cartier would evolve into many different models, and hints of its iconic design are still seen in current collections.

In tribute, a lounge within the Cartier Fifth Avenue Mansion in New York — which is opening in mid-September after a two-and-a-half-year renovation — is dedicated to Santos-Dumont.

The watchmaking tradition carries on today in the Santos 100 Carbon Watch, which houses the newly developed caliber 1847 MC movement, named for the year Cartier was founded, within a scratch-resistant carbon-coated case.

Entirely developed, manufactured, and assembled by the Cartier Manufacture in Switzerland, the Santos 100 has an automatic movement and a dual-direction winding automatic mechanism mounted on a ball bearing to provide great durability and stability.

The Santos de Cartier Collection continues to captivate fans around the world more than 100 years after it was introduced. This tremendous feat of design and function has graced the wrists of prolific writers, world-class entertainers, brilliant athletes, and accomplished designers alike.

On August 24, a 6.2-magnitude earthquake devastated thousands of buildings in central Italy. An estimated 3,000 people lost their homes, 292 people were killed, and police and firefighters are still searching through the debris.

Italy is now working to rebuild its towns to be more resistant to future earthquakes, and a renowned architect is stepping in to lead the effort.

According to The Guardian, Prime Minister Matteo Renzi is consulting Renzo Piano for help with the reconstruction.

Renzi recently met with Piano to lay out a national recovery plan, which will take 50 years to implement fully. It will begin with moving displaced residents to camps and shelters, and then shift focus toward changing and strengthening laws that regulate buildings' levels of earthquake safety.

Renzi solicited Piano's help because Piano is simply one of the best architects in the world. In 1998, he won the Pritzker Prize, often considered the Nobel Prize of architecture. He is known for his geometric, high-tech designs, which are often characterized by open layouts and strong lines.

Some of Piano's most notable works include towers like the The New York Times Building in Manhattan, the Centre Georges Pompidou in Paris, and The Shard in London, the tallest skyscraper in the European Union.

The architect has previously worked with UNESCO on disaster recovery and prevention, and has designed earthquake-safe buildings in Japan and California as well. He'll draw on that experience in this new undertaking.

"We have to act quickly, with the utmost urgency," Piano told The Guardian. "Anti-seismic requirements must be inserted in the laws of the country to make our homes safe, just as it's compulsory for a car to have brakes that work."

Piano is already calling for stricter building regulations and ways to protect the country's historic architecture against future disasters.

Business Insider recently released its annual list of the best colleges in America, which emphasized schools with high graduation rates, early-career earnings, and top-notch student life experiences. 

The ranking also took into account the annual net cost of each school — the average cost of tuition for all students that applied for financial aid, after accounting for the amount of financial aid received — according to the US government's College Scorecard.

Private colleges dominated the list, with 42 of the top 50 spots. While private schools typically have higher tuition, they also tend to award generous financial aid to students, effectively trimming annual net cost for students, leading to a higher ranking on the overall list.

Here are the top-25 best private colleges in America.

If you're a burger lover from the Pacific Northwest, you know Burgerville.

While classic chains such as McDonald's and In-N-Out dominated Foursquare's state-by-state analysis of the most popular fast-food chains in America, Oregon has a favorite that is unfamiliar to most of the country: Burgerville.

The 40-unit chain is known for its fresh food and local ingredients, making it a mega hit in Oregon and Washington. However, while the better-burger market seems pretty stuffed with competition, Burgerville is no newcomer — the first location opened in 1961.

The menu is filled with high-quality takes on traditional fast-food fare, with an emphasis on local foods. According to Burgerville, 72% of ingredients come from within 400 miles of headquarters in Vancouver, Washington.

The burgers' beef is antibiotic-free, never frozen, and raised on a cooperative of family ranches in the Pacific Northwest. Dairy for milkshakes is sourced from regional farms.

The menu also has some items that you wouldn't find at most fast-food joints, like the Wild Smoked Salmon and Hazelnut Salad and the vegetarian Anasazi Bean Burger.

Burgerville serves up a variety of seasonal sides, including fried asparagus and superthick Walla Walla onion rings.

The chain's commitment to sustainability goes beyond the menu. Burgerville recycles cooking oil into biodiesel and purchases wind energy credits equivalent to 100% of the power used at the corporate office and restaurants.

The one drawback of the local-food model is that it creates difficulty when it comes to growing the business outside of the Pacific Northwest. As a result, the chain has focused on appealing to potential customers in Oregon or Washington — including those just traveling through the states.

When nearing the edge of Burgerville territory on highways, the chain has posted signs warning drivers that, should they continue, they will be passing the last Burgerville for more than 24,000 miles. For those traveling by plane, the chain has a different solution — hydroflask stainless steel containers to keep milkshakes cold for up to eight hours are sold at the Portland airport location.

The regional chain has a few other quirks that make it unique. For example, it's one of the few fast-food chains to allow bikes at drive-thrus, as well as a rare chain with unionized workers.

These peculiarities seem to be part of what makes Burgerville lovers so passionate about the chain.

Burgerville may not expand beyond the Pacific Northwest anytime soon. However, if you're in the area, Oregonians believe that you can't find a better burger anywhere else.

The early birds will inherit the earth.

At least, that's what a 2009 University of Leipzig study found. The researchers concluded that "morning people were more proactive than evening types."

However, being an effective early riser isn't just about waking up before everyone else. It's about putting yourself in a positive mindset and getting important things done before everyone else.

So there's no point in setting your alarm clock at a crazy early time if you're just going to zone out in front of the television for a bit before slouching off to work.

In order to to start your day right, you've got to get into some good habits.

Here are seven morning rituals that may seem hard to adopt, but will ultimately reap major rewards, if you stick with them:

Jenna Goudreau contributed to a previous version of this article.

SEE ALSO: I tried waking up at 4 a.m. every day like Pepsi CEO Indra Nooyi, but I ended up creating a perfect morning routine for myself

DON'T MISS: I followed Benjamin Franklin's daily schedule for a week, and the most rewarding part was also the most difficult

Make a plan the night before

This isn't a morning ritual, per se, but it's a habit that's definitely conducive to a productive morning routine.

So make sure to set yourself up for a successful morning by creating a game plan the night before.

It's always helpful to have everything you need for the day laid out and ready to go when you wake up. Make sure you're stocked on whatever you need for breakfast. Write out a little schedule on what you need to accomplish the next day.

This all sounds pretty simple, but when you're getting home at night, it's very tempting to just crash on the sofa with a glass of wine and leave all the thinking for tomorrow.

Wake up painfully early

Sorry, night owls. It's time to adapt.

In a poll of 20 executives cited by Laura Vanderkam, a time-management expert and the author of "What the Most Successful People Do Before Breakfast," 90% said they wake up before 6 a.m. on weekdays. PepsiCo CEO Indra Nooyi, for example, wakes at 4 a.m. and is in the office no later than 7 a.m. Meanwhile, Disney CEO Bob Iger gets up at 4:30 to read, and Twitter CEO Jack Dorsey is up at 5:30 to jog.

Yes, this might sound awful, but if you get to sleep earlier, that'll numb the pain of such early wake ups over time.

The bottom line: Productive mornings start with early wake-up calls.

Start the day right with exercise

Yeah, there are those super humans among us who crave that pre-sunrise workout (or are they just really good liars). Still, for everyone else, waking up at the crack of dawn to sweat and get sore probably doesn't sound ideal.

However, the morning is probably the ideal time to exercise. By starting your day with exercise, you'll prevent yourself from putting it off.

Think about it this way — if some of the busiest people in the world can find time to workout, so can you. For example, Vanderkam notes that Xerox CEO Ursula Burns schedules an hour-long personal training session at 6 a.m. twice a week.

US President Barack Obama starts out each day with strength and cardio training while Twitter CEO Jack Dorsey does three repetitions of a seven-minute workout, as Anisa Purbasari reported for Business Insider.

"These are incredibly busy people," says Vanderkam. "If they make time to exercise, it must be important."

When you're in your early 20s, you learn a lot of valuable life skills that you take with you for the rest of your life.

Some of the most valuable skills men can pick up are related to grooming themselves. In the awkward teen and college years, men can sometimes get away with not knowing things like how to apply cologne or how to start a skincare routine.

But by the time you turn 25, there's really no excuse. It's time to straighten out your grooming routine.

Here are 6 grooming skills every guy needs to master before they turn 25.

How to shave properly.

How to apply deodorant correctly.

It's part of your normal morning routine: You shower, brush your teeth, and apply your underarm antiperspirant or deodorant every day. But it turns out that the time of day you apply your antiperspirant does matter a bit.

The best time to put on your antiperspirant or deodorant is at night, right before you go to bed. That's because it takes time for your antiperspirant to work its magic and close your armpit's sweat ducts.

After this process happens, good antiperspirants and deodorants usually last 24-48 hours, so you'll have plenty of dry times ahead after application. If you're concerned your morning shower will remove the antiperspirant effects of the night before, worry not: they'll continue working their magic, as the aluminum salts have already clogged the sweat ducts at that point.

How to apply cologne correctly.

Fragrance is tricky. The oils are designed to be absorbed and melded with your skin's natural oils, creating your own unique scent. That can't happen when you apply it to your clothing, so you should never apply fragrance to anything but your skin.

The ideal place to apply cologne is the area between your chest and neck, inclusive of both. A bonus is that some men have chest hair, which can trap some fragrance oil, increasing how long the smell might last on their skin.

As for amount, remember the cardinal rule of applying cologne: less is most certainly more. "Cologne should be discovered, not announced," as Art of Manliness says. Overdo it, and you'll give everyone around you a headache.

Finally, after you apply the cologne, pat it on your skin, but do not rub it in.  Rubbing it in can cause it to be absorbed by your skin more quickly, and it can even distort the scent.

Wealth inequality is a mounting issue in America. A new study from online real-estate broker Trulia provides insight into one potential driver of the wealth gap: real estate.

In its study, Trulia compared median home values in 1986 and 2016 for the 100 largest metro areas. They found that homes in the priciest US housing markets from 1986 gained value at a much higher rate over the past 30 years, growing comparatively even more expensive rather than converging with other cities.  

Homeowners in California metros like San Francisco, San Jose, and Orange County — three of the most expensive housing markets in both 1986 and 2016 — have experienced an appreciation in home value of at least 299% over the past three decades on average. Metro areas like Rochester, New York, and Wichita, Kansas, fared significantly worse, with homeowners getting less than a 90% return on home value over the same period — the lowest figures in the study.

In short: Rich homeowners are getting richer, and average homeowners aren't.

Real estate in the West (in metros in California, Oregon, Washington, and Hawaii) earned the highest return, taking the nine top spots in Trulia's ranking. Trulia concluded that income growth and new housing construction are likely contributors to the growth of a region's housing market — two factors that are abundant on the West Coast.

Taylor Swift topped Forbes' Celebrity 100 list this year with reported earnings of $170 million.

Over the years, she has used her money to purchase and rent a number of incredible residences across the US, from Beverly Hills, California, to Nashville, Tennessee, where she made her name as a country star.

We've previously taken a look inside Swift's $17 million seaside Rhode Island mansion— which she reportedly paid for in cash in 2011 — and her new $40,000-a-month townhouse in New York's West Village.

All told, she's spent about $44 million buying real estate (not counting her rental).

Dress codes are intimidating — there's no doubt about that. But with a little knowledge and a flexible wardrobe, you can conquer any hyper-specific dress code thrown at you.

If you're the type of guy who freezes up when he sees an event invitation with the words "cocktail attire," it's time to listen up.

From black tie to casual, here's what to wear when you have to look appropriate.

SEE ALSO: The most surprising thing about wearing a $6,000 Rolex for a month straight

DON'T FORGET: Follow Business Insider's lifestyle page on Facebook!

Black tie is often considered the pinnacle of modern formality (aside from white tie, which has been completely forgotten about, and is almost never worn aside from royal weddings). Attendees of evening events are, however, sometimes requested to wear black tie.

If that's the case, here's what you need to wear:

- A completely black tuxedo with a white formal shirt featuring a wing collar, finished with a black satin bow tie. Sometimes a black satin cummerbund is added, but that is becoming less and less common.

- Black socks and black patent leather shoes are non-negotiable for footwear here.

All three of these essentially mean the same thing: You're going to be wearing a suit.

If you see "black-tie optional" on an invite, know that wearing a tuxedo is not required, but whoever sent the invitation will most likely be wearing one.

An appropriate outfit could include a navy suit with a formal dress shirt and a dark-colored necktie. Cocktail attire is the least formal of the three, while business formal gives you the least leeway here.

Business casual is today's standard office dress code, and it's a lot more freeform than any of the stuffier dress codes.

Jackets are optional but encouraged. Dress pants or chinos are required, as well as a collared shirt and leather shoes.

Jeans are becoming more and more tolerated with every year. If you're going to wear them with a business casual outfit, ensure they are well-fitting, without tears, and in a dark wash.

The words "dressy casual" on an invitation indicate that the party is not formal, but that the host is expecting a little something extra. Throw a blazer on.

There's a lot of debate about the pros and cons of private versus public colleges. But when you get down to the numbers, many great schools exist both categories.

Business Insider recently released its annual list of the 50 best colleges in America, which emphasized schools with high graduation rates, early-career earnings, and top-notch student life experiences. The ranking also took into account the annual net cost of each school — the average cost of tuition for all students that applied for financial aid, after accounting for the amount of financial aid received — according to the US government's College Scorecard.(Read more about the methodology here.)

Business Insider expanded its scope to the top 100 schools and then filtered the ranking to highlight the best public institutions in the country — many of which provide an excellent education at a very low net cost. 

The University of Virginia topped the list, earning a top 10 spot on the main ranking as well. University of Michigan at Ann Arbor and University of California at Berkeley rounded out the top three.

The Faroe Islands, an archipelago under Danish control in the North Atlantic Ocean, is now the site of a fascinating Google project.

Because the islands are remote, Google never bothered to map them for Google Maps Street View.

So several citizens went about trying to get Google to come and photograph the islands' grassy hills and beautiful coastline. 

The islands are only home to about 50,000 people, but there over 70,000 sheep live there. So a couple of Faroese decided to strap cameras to the sheep and map out as much of the islands as they could.

Google does allow independent people to contribute to Street View. 

Google loved the effort, and announced on Wednesday that it's loaned official Street View equipment and a couple of professional 360-degree cameras to finish the job.

Although cultural generalizations can be overly reductive, Lewis, who speaks 10 languages, insists it can be done fairly. "Determining national characteristics is treading a minefield of inaccurate assessment and surprising exception. There is, however, such a thing as a national norm," he writes.

It seems as though Airbnb is trying out something new for its celebrity guests: subletting for free.

According to a report from TMZ, the San Francisco-based home rental startup is providing a multimillion-dollar penthouse through October for two celebrity guests: Kim Kardashian and Kanye West. The home usually costs guests $10,000 per night, but TMZ reports that Airbnb is picking up the tab. 

It's not clear what Airbnb is getting out of the deal, but previous reports said that Kim Kardashian will likely post on social media about the apartment throughout her time there. She has already posted on Instagram about the place and tagged Airbnb.

Boasting a rooftop pool, five bedrooms, six bathrooms, and a home gym, the penthouse is reportedly on the market for $24.5 million. The "insane" penthouse is listed by real estate agent Andrew Azoulay, but reportedly is owned by hedge funder Harsh Padia. In September 2015, the penthouse was on the market for an asking price of $30 million. 

Take a tour of the 7,000-square-foot home.

If you're at all attuned to America's real estate market, you've heard about San Francisco's ongoing housing crisis.

Residents have been doing crazy things to survive the sky-high cost of living, from camping out in Google's parking lot to taking up residence on a sailboat. 

But according to a recent report by online real-estate broker Trulia, the story is slightly different for San Francisco's longtime homeowners, who are enjoying incredibly high rates-of-return on their homes.

In 1986, America's most expensive housing market was San Francisco, where the median value of a home was $160,955. Today, it remains the country's most expensive housing market, with a median home value of $1,058,474. That's a 557% rise over 30 years, more than any other US metro area.

New York City is an extremely cosmopolitan place, and walking around the city, one often hears a plethora of languages being spoken.

The American Community Survey is a massive annual effort by the Census Bureau to measure various aspects of American life. Among many other things, respondents are asked if they speak a language other than English at home, and if so, what language is spoken. Using this data, as explained in more detail at the bottom of this post, Business Insider was able to map out New York City's most popular non-English languages.

First, here's the most commonly spoken non-English language in each NYC community district. Unsurprisingly, Spanish is pretty dominant. There are quite a few Chinese speakers in the southern Brooklyn neighborhoods of Bensonhurst and Bay Ridge, and in Flushing, Queens, and a few other language enclaves scattered around the city.

Because Spanish shows up in so many neighborhoods, we made an alternate version of the map where we found the most common non-English, non-Spanish language:

The maps were made using the ACS Public Use Microdata Sample, an edited version of the individual responses to the survey. With this data, we were able to calculate the most commonly spoken non-English language in each of New York City's Census-designated "Public Use Microdata Areas," which closely conform to the city government's community districts, for which the city provides very nice-looking map outlines.

Buying a home isn't just a 20% down payment and a monthly check for the mortgage.

There are a mountain of hidden costs — from closing fees to taxes — that can add up to more than $9,000 each year, real estate marketplace Zillow estimates — and that number will only jump if you live in a major US city.

For every man experiencing hair loss, there comes a time when you need to make a decision. Do you continue to fight it, or do you just embrace it?

American tennis legend Andrew Agassi went through that process publicly, right in the middle of his career.

The eight-time Grand Slam winner says it all started when he began losing his hair around the age of 19. To hide it, he grew his hair into its famed mullet shape, admitting in his 2010 autobiography "Open" that he sometimes wore hairpieces to hide the regression.

Finally, Agassi shaved his head in 1995, at the tender age of 25.

"When I did that, I never felt freer in my life," Agassi told Business Insider at an event promoting his new charity-focused partnership with Lavazza coffee company. "It was like a weight off my shoulders."

"I hated feeling like a fraud. When you're not honest with yourself — that [feeling] got very tiring for me."

As for any advice Agassi has for men going through the same thing, his is pretty simple.

"The most precious thing we have in life is time, so any time you spend worrying about something, get rid of it," he said. "Why spend a moment worried about something? Life is too short for that."

As for regrets, Agassi has at least one: his signature late '80s/early '90s mullet.

"The truth is that if I found a picture of myself like that, I'd probably burn it," he said.

Agassi also said he regretted waiting so long to completely shave his head, but admitted that there were some benefits to delaying it.

"In a sense it was good timing too, because it took a lot of people on the journey with me," he said, in reference to the sudden media attention shaving his head brought to him and the issue.

So take it from one of the most successful shaved athletes and men in the world: if you're balding, just shave it. Be true to yourself. After all, it's just one less thing to worry about.
