Nicotine is the natural, highly-addictive substance in tobacco, and it takes as little as seven seconds to reach the brain after you inhale a drag from a cigarette or other device, according to the World Health Organization.

Once it reaches our brains, nicotine can dramatically raise the activity level of feel-good chemical signalers deep in our brain's reward system.

This key effect is actually what all abused drugs, including nicotine, appear to have on our brains.

As a result, using nicotine or other addictive drugs doesn't just make us feel euphoric — it also makes us want to use again.

The producers at the infographics site Column Five recently made this graphic to show how quickly and easily our bodies can become primed to use nicotine.

The Germans are famous for using long words used to describe hyper-specific, complex sentiments. For instance, the 26-letter word vergangenheitsbewaeltigung describes the inability to cope with the past. And, of course, schadenfreude reflects the happiness you derive from somebody else's pain. 

In honor of Oktoberfest, which wraps up this weekend in Münich, we have entmystifiziert, or “demystified," our favorite German expressions that have no clear English meaning.

Here are "acht" (eight) of our favorite German words:

1. Sauregurkenzeit

A typical German vacation, which can last anywhere from three to six weeks in July through August, is referred to as the Sauregurkenzeit. This literally translates to "pickle time," possibly because cucumbers come into season in the summer. This is the "off-season" where nothing happens because everyone is away. Washington, D.C. experiences a Sauregurkenzeit during Congress' five-week summer recess.

2. Torschlusspanik 

Imagine that all your friends are getting married, moving to the suburbs, and having children while your love life consists of matches on Tinder. That brutal feeling of  "anyone will do at this point cause I'm not getting any younger" is torschlusspanik.

3. Frühjahrsmüdigkeit

This 18-letter word is used to describe a general sense of weariness in the springtime, specifically between mid-March through mid-April. In German, the word Frühjahr means "springtime," and Müdigkeit means "tiredness." Conjoined, Frühjahrsmüdigkeit is "springtime lethargy."

4. Erbsenzähler

Anyone who's obsessed with details and a bit of a control freak would be referred to as an Erbsenzähler. The word Erbsen means "peas" and Zähler means "tally." Therefore, an Erbsenzähler literally describes a person who counts their peas.

5. Honigkuchenpferd

By dissecting this word, you have "horse-shaped honey cake." Literally, it means having a giant dorky grin on your face. If your mom embarrasses you in front of your friends, you're probably going to have a honigkuchenpferd-looking smile. German dictionaries translate this word as the action of "grinning like a Cheshire cat" given the wide-sweeping smile from the Cheshire cat in "Alice and Wonderland." 

6. Backpfeifengesicht 

This word essentially means "a face that is begging to be punched." The word Backpfeife means either "punch or slap" and Gesicht means "face." The German punk bank, Die Ärzte, named one of its songs Backpfeifengesicht since the lyrics mention a person who's apparently wearing a stupid look that frustrates the singer.

7. Geborgenheit

The feeling you get when sitting near a warm fire, while wrapped in a blanket, when it's cold and rainy outside is geborgenheit. The word describes a sense of security, coziness, and comfort.

8. Pantoffelheld

A man who may act tough in front of his friends but can't stand up for himself against his wife is what Germans call a Pantoffelheld or a "slipper hero." The first part of the word, Pantoffel means "slipper" and the latter, Held means "hero." The closest English reference would be someone who is "whipped" by an overbearing partner.

There is currently a gigantic camera being built in the mountains of Chile, in the foothills of the Andes, that will be like nothing we've ever seen before. While the new iPhone 6S camera may have just upgraded from eight megapixels to 12, this will have a whopping 3,200 megapixels — making it a 3.2 billion pixel camera.

Named the LSST, or the Large Synoptic Survey Telescope, it is set to be the largest camera in the world. Scheduled to be finished in 2019, it will combine a telescope, mirror, camera, data system, and survey technology. 

This thing is going to huge. It's just one addition to a class of giant land-based telescopes coming online in the next decade. It will have a lower enclosure 100 feet in diameter, a service and operations building of 32,000 square feet attached to it, as well as another section for the calibration telescope. 

What it will do

The LSST will record the entirety of the visible nighttime sky twice a week, taking over 800 panaromic images during each of those nights. This will result in 30 terabytes of data each evening.

From these captures, it will produce an animated 3D map of the universe. With a large depth of details, these maps will allow us to analyze the solar system in a new way, including studying mysterious dark matter and learn more about our own Milky Way galaxy.

How it will work

The LSST will focus on capturing images of space at night. It's able to cover 10 square degrees of sky (which, for reference, is equal to 40 times the size of the moon). This ability comes from its large mirror and field of view, which work hand-in-hand to capture billions of objects that are too faint to be seen with the naked eye.

The powerful data system will be able to keep track of the brightness and positions of space objects, like galaxy clusters and asteroids, as well as comparing the images being taken in the present with those of the past. This even includes detecting and keeping track of asteroids that might be threatening to Earth. 

Access to the findings

Luckily, these maps won't be an exclusive experience to scientists. The public will be able to view the moving 3D map via the internet each night as it captures the sky.

These new, highly detailed images will allow us to see billions of objects in space that we can't with our own eyes.

Education is important to the team behind the LSST. The group is also planning to develop research projects which students can do in school, in their home, or out at museums.

Why Chile?

Telescopes are almost never located in highly populated areas because of the threat of light pollution. Cloud cover can also be a problem, so they are also usually put at higher altitudes and in drier climates. 

Cerro Pachón, the mountain in Chile where the LSST will be located, was chosen as the best option by an appointed committee. 

Construction started in 2014, and it's scheduled to be completed by 2019.

The 2016 "Michelin Guide to New York" was announced earlier than originally planned Wednesday night, thanks to social media.

According to the website Eater, Michelin called certain chefs to let them know that they had earned or maintained their star(s), and the chefs then shared the news on social media.

As for the big winners, the six three-star restaurants from last year maintained their status. Since 2011, when Chef's Table at Brooklyn Fare and Eleven Madison Park were inducted into three-star fame, the Michelin Guide hasn't added any new restaurants to its top echelon. But it has demoted one restaurant, Daniel, to two stars.

In all, 10 new restaurants were added to the one-star list this year, and Danny Meyer's The Modern was elevated from one star to two. The longtime favorites 15 East, Gotham Bar and Grill, Lincoln, and Seäsonal were among the restaurants to lose their star and fall off the list.

The biggest snubs were Annisa (upgraded to three stars by The New York Times in 2014), Cosme (from the chef behind the No. 16 restaurant in the world), and Sushi Nakazawa (one of only six New York City restaurants to earn four New York Times stars).

Here's the Michelin Guide's complete 2016 list:

Three Stars: "Exceptional cuisine, worth a special journey"

A sprawling Los Angeles estate that formerly belonged to Sam Simon, the late co-creator of "The Simpsons," has hit the market for $18 million.  

With a property that totals about 1.5 acres, the residence actually includes two homes: a chic modern residence and a second, more historic home designed by architect Richard Neutra in 1948. The house was part of Arts & Architecture magazine's postwar Case Study House Program, which commissioned architects to build affordable and modern homes.

Simon died in March 2015, after a battle with colon cancer. According to the Wall Street Journal, the property is being sold by Simon's estate, and the proceeds will be donated to charity.

La Bouitte, meaning "little house" in the local dialect, was once just that, in the middle of a potato field in Saint-Martin-de-Belleville, purchased by a French couple in 1976. Over the years, remaining in the family, it has turned into a luxury chalet, surrounded by the Saint-Marcel ski slopes and boasting a restaurant with three Michelin stars, helmed by a father and son duo. The food, like the chalet, manages to be both modern and rustic — think haute comfort food — and is inspired by the surrounding mountains and lakes, with ingredients like lake trout and chanterelles from the forest.

Gunnar Garfors had already traveled to all 198 countries in the world when he decided to tackle another travel feat: traveling to more than 19 countries in 24 hours.

Last year, Garfors and his two travel companions, Øystein Djupvik and Tay-young Pak, managed to break a record and make it to 19 countries in one day.

This year, they set out to break another record and make it to 22 US states in 24 hours. And they succeeded.

Garfors said the three friends made the trip for two main reasons: the adrenaline rush that comes with trying to beat a record, and as a kind of promotional tour for the book he just released. 

They traveled mostly by car — and admittedly broke some speed limits — but also took a few flights.

There were some states where the group spent more time than others due to a flight delay or lots of driving, and then there were states where they only hopped out to take a photo or grab food.

Here's a map of the route the group took. According to Garfors, a fair amount of planning went into the route.

And here's the complete list of states they visited in order:

1. Maine

2. New Hampshire

3. Massachusetts

4. Connecticut

5. Rhode Island

6. Vermont

All the actors who've played James Bond left a stylish footprint on the franchise.

It's nearly impossible to judge which Bond has the most sartorial swagger.

But we did it anyway.

6. Roger Moore

By putting Roger Moore in sixth place, we're by no means saying his Bond had no style. Again, all Bonds are stylish — and products of their time.

Unfortunately, Moore's 1970s style is a bit grandfatherly. Wide, patterned ties and gray, patterned sport coats do not make a very debonair James Bond.

5. Timothy Dalton

Timothy Dalton's Bond wore all the right clothes, from tuxedos to high-collared suits. But he didn't wear them convincingly.

He looked out of place in every suited-up scene, as if he much preferred combat gear. Dalton treated formal threads like a uniform he couldn't wait to take off. 

4. Pierce Brosnan

Pierce Brosnan's Bond knew how to rock a suit. Unfortunately, they made him look more like an international mogul than a slightly unhinged British secret agent.

He was a bit more convincing in a tuxedo — but he still looked like an executive at a charity gala, rather than an undercover spy.

Oktoberfest may be famous for beer being guzzled by the liter, but increasingly locals can be seen snorting a white substance from tables all over tents: and it's entirely legal.

Wiesn koks (Oktoberfest cocaine), which is also known as Wiesn Pulver (powder) or Bavarian cocaine, has become locals' pick-me-up of choice.

Essentially like snuff, Wiesn koks is made of glucose and menthol, and is sold in little glass bottles or Bavarian themed containers for almost $6. You may have read about giant masses and Lederhosen in your guidebook, but you won't find Wiesn koks in there.

The powder is cut into lines on beer tables, or, since those are usually covered in sticky beer, tapped out onto the back of hands, to be snorted through nostrils.

Despite looking like the real deal, Wiesn koks is harmless. Sure, you get a small sugar rush when it hits, and the menthol has a cooling, sinus-clearing effect, but that's about it. Wiesn koks is entirely drug and tobacco free.

That said, it's all about moderation: snuff too much and you might get yourself a bloody nose.

And despite being harmless, tent owners and security personnel have been trying to crack down on the tradition for years. However, locals refuse to give up this bit of culture, because that's really what it is: a cultural, seasonal tradition that basks in revelry and camaraderie.

The movie based on Michael Lewis' best-selling book "The Big Short" will be coming out in December.

The official trailer was recently released, and we can hardly wait to see some of Hollywood's biggest names playing the heroes of the financial crisis— Steve Carell as Steve Eisman, Christian Bale as Michael Burry, Ryan Gosling as Greg Lippmann, and Brad Pitt as Ben Hockett.

Like the book, the film chronicles the stories of this group of Wall Street outsiders who accurately predicted the housing crisis and made a fortune betting against subprime-mortgage bonds.

If you haven't read it yet, we recommend that you do. It's full of incredible details. One in particular that stands out is a passage on the observations of former FrontPoint head trader Danny Moses.

Moses, described as the small-picture guy on Steve Eisman's team, claimed he could tell a lot about a guy just by looking at him.

The best place to study Wall Street people was on the morning commute from Connecticut. Moses estimated that 95% of the people on his morning Metro North train worked on Wall Street.

Just by looking at them, he said, he could tell at a glance what their jobs were and where they worked.

[The following text is excerpted from The Big Short.]

If they were on their BlackBerrys, they were probably hedge fund guys, checking their profits and losses in the Asian markets. [Given the book was based on 2008, you can probably swap BlackBerrys then for iPhones today.]

This is an excerpt from Michael Lewis' The Big Short (pp. 235-237).

If they slept on the train they were probably sell-side people — brokers, who had no skin in the game.

This is an excerpt from Michael Lewis' The Big Short (pp. 235-237).

Anyone carrying a briefcase or a bag was probably not employed on the sell side, as the only reason you'd carry a bag was to haul around brokerage research, and the brokers didn't read their own reports — at least not in their spare time.

This is an excerpt from Michael Lewis' The Big Short (pp. 235-237).

Robert F. Smith, CEO and founder of private equity firm Vista Equity Partners, just graced the cover of Forbes' richest Americans issue.

With a net worth of $2.5 billion, he's ranked No. 268 on Forbes' list of wealthiest Americans.

That puts Smith ahead of early Facebook investor Jim Breyer, who has a net worth of about $2.4 billion, and on par with private equity veteran and Philadelphia 76ers co-owner Josh Harris, who has earned $2.5 billion to date.

He also displaced Michael Jordan, becoming the second-richest African-American in the US — behind Oprah Winfrey.

It's the latest accomplishment in a stellar 12 months for the leader of one of Silicon Valley's budding software and technology investors. Last October, Smith and Vista closed a fund nearing $6 billion, the firm's biggest ever.

He also got hitched to Hope Dworaczyk, mother of his young son, in a wedding that can only be described as epic.

Check out scenes from the life of one of private equity's rising stars:

He faced an uphill battle in Silicon Valley from early on

Smith gave the commencement speech at American University's 2015 graduation, where he spoke about his earliest attempts to get work in Silicon Valley while he was still in high school. 

"I dug up the phone number for Bell Labs to ask about summer internships. They said I could apply if I were a junior or senior in college. I said that was fantastic, because, while I was only a junior in high school, I was getting A’s in computer science and my advanced math courses, so it was like I was in college. Much to my dismay, they disagreed."

But he was persistent and eventually got his way. 

"I called back every day for two weeks straight. The HR director stopped taking the calls after the second day but … I left a message with my phone number. Then I called every Monday for about five months, and every Monday the receptionist chuckled and took a message. I kept at it. To my great surprise, Bell Labs HR Director finally called me back — in June. An intern from MIT hadn’t shown up, and they needed someone fast."

Smith spent years working as an intern at Bell

Smith attended Cornell for undergrad but he never lost touch with Bell Labs. He continued to do work there as an intern during his summer and winter breaks before graduating Cornell with a chemical-engineering degree. 

After Cornell, Smith headed to Columbia University

Smith would go on to earn his MBA from Columbia University. Afterward, he headed straight to Wall Street, taking a job at Goldman Sachs. "When I finished business school and decided to join the tumultuous world of investment banking, my family and friends spoke up with concerns about my sanity," he said in his American University commencement speech. 

Smith would rise to cohead of enterprise systems and storage-investment banking, advising on $50 billion of deals from 1994 to 2000.
