Writers, anthropologists, historians make use of written records, relics and works of art to tell a complete story but now researchers from the University of California Berkeley and Brown remind us that there is another path to humanities research, and this is where computer and social sciences cross paths. "We demonstrated the use of various techniques for mining visual patterns and trends in the data that significantly decrease the time and effort needed to arrive at the type of conclusions often researched in the humanities."
Smiling is a relatively recent phenomenon in the history of photography. Finally, the researchers group the photos by decade and then blended the faces to create a single "average" face for each decade. Here's how smiles have changed for men over the past century: Here's how smiles have changed on women's faces during that same period: As you can see, for both men and women, portraits evolved from being a mere twinkle in the eyes in the 1900s to toothy smiles in the 2010s.
Turn-of-the-century photographers used to tell subjects to say "prunes" rather than "cheese," so that they would smile less. The main challenge for the team was to collect enough photos to create an "average" student profile for each decade from the 1900s to the 2010s. The group hopes to use the dataset to study things like "the cycle-length of fashion fads."
The photos with the closest smile to the average for that 10-year period. It shows a rapid increase in the intensity of smiles between the 1900s and 1950s, a trend that continues today. From "prunes" (left) to "cheese" (right): Lip curvature was used to measure the intensity of smiles.
We take it for granted that, when someone takes our photo, we should smile for the camera. This "lip curvature metric" measures the angles at the corners of the mouth - basically, how far the corners of the mouth curve upwards. The next two images below show the men and women with the smile closest to the average smile of the 10-year period, from 1905 to 1955 and then 1965 to 2005.

Data mining helped researchers show how smiling evolved from the 1900s up to the present day. "We demonstrated the use of various techniques for mining visual patterns and trends in the data that significantly decrease the time and effort needed to arrive at the type of conclusions often researched in the humanities," the authors concluded in their study.
There's a reason why people 100 years ago looked miserable. A new study has revealed how our smiles have evolved in photographs as a direct result of improving technology. The research was done using a new data-mining tool, which can reveal patterns in anything from phone conversations to behaviour on social media. There's a reason why people 100 years ago looked miserable in history books.
In a study of undergraduates, women who expressed sincere joy in their college yearbook photos were relatively more likely to be married by age twenty-seven and more likely to have satisfying marriages at age fifty-two. Studies show that people who tell more vivid and engaging narratives have higher well-being later in life. Many on Facebook applied the filter of the French tricolour on their pictures to create a memory for themselves. I posit that perhaps it was more than a memory.
Kirk Ambrose was a junior when this photo appeared in the 1963 Hardin-Simmons University yearbook. photos by Eric J. Shelton/Reporter-News Abilene Christian University sophomore Erica Greene prepares to take a quiz in her Greek class on Wednesday. Bryon Martin, assistant director of multicultural enrichment and support at ACU, said students at the school started writing letters in the 1950s to the college's paper, The Optimist, that segregation was wrong.
New, previously unpublished childhood photos show the 39-year-old country star, The Voice coach and upcoming Kids' Choice Awards host sporting glasses, a large gap on the side of his front teeth, a little bit of baby fat, some flannel and, oh yeah, a sweet, sweet curly mullet. "I mean I was playing the guitar by the time I was 15," he told Jimmy Kimmel.
Anne Hathaway 's certainly been having a fun, girl-power week of celebrating her female friends. Speaking again with Glamour UK , she said, "She just seems to be following her heart. I met her -- I hope it's OK to say this -- when she and Jake [Gyllenhaal] were together. She was 20 at the time, and we hung out one night. I was like, 'You are a magnificent creature.' She was on fire and I've watched her become this force of nature."
