Mona Lisa’s “twin” heading to the Louvre

A second painting of the Mona Lisa by one of Leonardo Da Vinci’s students is now on display at the Prado museum in Madrid, Spain and headed to the Louvre on March 13 to join the famous original. A “technical study” requested by the Louvre shed light on the twin previously believed a recent copy. During the study, experts learned of hidden mountains and other similarities to Da Vinci’s painting, leading them to believe Da Vinci’s student painted it. I wonder how many other works of art have been mistaken because the time was not taken to verify them. Read the full Madrid’s Prado puts Mona Lisa’s “twin” on display story at Reuters.

Can numbers explain everything?

British scientists have created an equation that can predict the shape of any ponytail using the Rapunzel Number, a ratio that accounts for the effects of gravity on hair relative to its length. Seems unimportant, but these new statistics, which solve an issue that has puzzled mathematicians since Leonardo da Vinci about 500 years ago, should help the computer graphics and animation industries represent hair better. Someday we may not need real people in film. Learn more in the Rapunzel number helps scientists quantify ponytails story at Reuters.
