Teenage science explainer wins scholarship for brilliant explanation of quantum tunneling

Maryam Tsegaye, a 17-year-old science adept in Fort McMurray, Alberta, entered a global contest called the "Breakthrough Junior Challenge", in which you create a YouTube video to try to explain a complex scientific concept to everyday folks.

Tsegaye tackled quantum tunneling, and did an absolutely fantastic job of taking its probabilistic weirdness and making it graspable. Seriously, go watch the video: She is all clarity and charisma.

Tsengaye won the contest, which gives her a $250K scholarship, $50,000 for her science teacher, and $100,000 for a new science lab at her school. They made a video of the moment Sal Khan told her she'd won, and it is super heartwarming.
