Was Mona Lisa Faking Her Smile?

Art is supposed to be a highly subjective experience, contradicting science's focus on objective conclusions. But a team of neuroscientists believe they've arrived at a definitive interpretation about Leonardo da Vinci's famous Mona Lisa. According to their research, the subject in the painting is putting on a forced smile.

In a paper published in the journal Cortex, researchers from the U.S. and Europe set out to examine the smirk of the painting's subject, believed to be a woman named Lisa Gherardini, whose husband commissioned the painting as a gift. First, they created chimeric images of the Mona Lisa's expression by bisecting her face and mirror-imaging the left or right sides to create full smiles. Then, they asked 42 study participants to describe the images from a list of six different emotions. Thirty-nine said the left side was expressing happiness. No one in the group labeled the right side as appearing happy. Most said it was neutral, while five said it was actually displaying disgust.

Conclusion? The happiness of the smile appeared only on the left, and was therefore asymmetrical and "non-genuine."

Coupled with their observation that the face of the Mona Lisa appears expressionless around the cheeks and eyes, the researchers surmised that the woman in the painting was appearing to be insincere. They argue that Leonardo likely took his model's blank expression and added a slight smirk on the left side: perhaps Gherardini simply couldn't maintain a pleased expression while sitting for the duration of the work. They also speculate that Leonardo may have known an asymmetrical smile was thought to be non-genuine and purposely depicted it to draw more reactions out of the painting's viewers.

It's also possible that none of these theories is correct. Like any great work of art, its meaning could remain enigmatic for another five centuries at least.

The Longest Movie Ever Made Would Take You More Than 35 Days to Watch Straight Through

A typical movie lasts between 90 minutes and two hours, and for some viewers, any film that exceeds that window is "long." But the longest film you've ever seen likely has nothing on Logistics—a record-breaking project released in Sweden in 2012. Clocking in at a total runtime of 35 days and 17 hours, Logistics is by far the longest movie ever made.

Logistics isn't your standard Hollywood epic. Conceived and directed by Swedish filmmakers Erika Magnusson and Daniel Andersson, it's an experimental film that lacks any conventional structure. The concept started with the question: Where do all the gadgets come from? Magnusson and Andersson attempted to answer that question by following the life cycle of a pedometer.

The story begins at a store in Stockholm, where the item is sold, then moves backwards to chronicle its journey to consumers. Logistics takes viewers on a truck, a freight train, a massive container ship, and finally to a factory in China's Bao'an district. The trip unfolds in real time, so audiences get an accurate sense of the time and distance required to deliver gadgets to the people who use them on the other side of the world.

Many people would have trouble sitting through some of the longest conventional films in history. Kenneth Branagh's Hamlet (1996) lasts 242 minutes, and Joseph L. Mankiewicz's Cleopatra (1963) is a whopping 248 minutes long. But sitting down to watch all 857 hours of Logistics straight through is nearly physically impossible.

Fortunately, it's not the only way to enjoy this work of art. On the project's website, Logistics has been broken down into short, two-minute clips—one for each day of the journey. You can watch the abridged version of the epic experiment here.
