Victoria Hart (born 1988), commonly known as Vi Hart (/ˈv hɑːrt, ˈv hɑːrt/),[3] is a self-described "recreational mathemusician" who is well known for creating mathematical videos on YouTube.[4][5][6] Hart founded the virtual reality research group eleVR and has co-authored several research papers on computational geometry and the mathematics of paper folding.[7][8]

Together with another YouTube mathematics popularizer, Matt Parker, 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".[9]


Hart is the child of mathematical sculptor George W. Hart, and received a degree in music at Stony Brook University.[4] Hart identifies as "gender agnostic".[10][11][12]

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,[4][13] eventually gaining the support of the Khan Academy and making videos for the educational site as their "Resident Mathemusician".[14][15] Many of Hart's videos combined mathematics and music, such as "Twelve tones", which was called "deliriously and delightfully profound" by Salon.[16]

Together with Henry Segerman, Hart wrote "The Quaternion Group as a Symmetry Group", which was included in the anthology The Best Writing on Mathematics 2015.[17]

In 2014, Hart founded a research group called eleVR, with Emily Eifler and Andrea Hawksley, to research virtual reality (VR). They created VR videos, and had also collaborated on educational computer games.[18][19][20][3][21] They created the game Hypernom, where the player has to eat part of 4 dimensional polytopes which are stereographically projected into 3D and viewed using a virtual reality headset.[22][23] In June, the group released an open source web video player that worked with the Oculus Rift.[24] In the same year Hart created the playable blog post Parable of the Polygons with Nicky Case. The game was based on economist Thomas Schelling's Dynamic Models of Segregation.[19][25] In May 2016, eleVR joined Y Combinator Research (YCR) as part of the Human Advancement Research Community (HARC) project.[26] Hart was listed as a Principal Investigator.[27]
