Victoria Hart was born in 1988, and is commonly known as Vi Hart.
She is a self-described "recreational mathemusician" who is well known for creating mathematical videos on YouTube.
Hart founded the virtual reality research group eleVR and has co-authored several research papers on computational geometry and the mathematics of paper folding.
Hart won the 2018 Communications Award of the Joint Policy Board for Mathematics for "entertaining, thought-provoking mathematics and music videos on YouTube that explain mathematical concepts through doodles".
Hart is the child of mathematical sculptor George W. Hart, and received a degree in music at Stony Brook University. Hart identifies as "gender agnostic".
Hart's career as a mathematics popularizer began in 2010 with a video series about "doodling in math class".
After these recreational mathematics videos - which introduced topics like fractal dimension - grew popular, Hart was featured in The New York Times and on National Public Radio, eventually gaining the support of the Khan Academy and making videos for the educational site as their "Resident Mathemusician".
Many of Hart's videos combined mathematics and music, such as "Twelve tones", which was called "deliriously and delightfully profound" by Salon.
