Pick of the Week
Industry leaders share their favorite videos and creative inspirations.
This week's guest curator is Gail Tifford, senior media director at Unilever.
Gail recommends you watch Khan Academy's "The Beauty of Algebra."
In her own words: "I love the fact that someone can make algebra simple and sexy. As a full-time working mom with children in high school and middle school, I admit my math skills are a bit rusty. I don't have much time to refresh them, so the Khan Academy has been a lifesaver!"
