Early life and education
Dianna Cowern was born on May 4, 1989 and raised on Kauai island in Hawaii.[1] Her father was a tree farmer and her mother ran a bed and breakfast.[dc 1] Through most of her early education, Cowern was fascinated by mathematics.[dc 1] She went to a high school with eighty students, crediting her two physics teachers with her interest in the subject.[1][4][5] During this time, she was inspired by Neil deGrasse Tyson and became interested in science communication.[6]
Cowern studied physics at the Massachusetts Institute of Technology (MIT), graduating in 2011 with a Bachelor of Science.[6] During her time at MIT, she researched dark matter under Jocelyn Monroe. After graduation, Cowern was a research fellow at the Harvard–Smithsonian Center for Astrophysics, where she researched low-metallicity stars under Anna Frebel.[7][8] After her fellowship, she moved to San Diego.[9]
Career
Summarize
Perspective
Cowern started her YouTube channel Physics Girl on October 21, 2011.[dc 2] Her first video, "What to do with a physics degree...", was made shortly after she finished college.[9] Cowern made it as a joke for friends, but it got more views than she expected.[4][5] As her videos gained viewers, she renamed her channel Physics Girl and shifted toward teaching physics concepts.[9]
When Cowern started making videos, she worked as an iPad app developer at General Electric.[8][10] She then worked as an educator at Fleet Science Center[9] and the outreach coordinator at University of California at San Diego's Center for Astrophysics and Space Sciences research unit.[1]
In 2014, Cowern won the top video prize in the Flame Challenge from the Alan Alda Center for Communicating Science at Stony Brook University, with the topic "What is color?", as voted by fifth grade students.[1][11][12] Her channel became popular around this time; in following months, she had some viral videos and collaborated with YouTubers such as Veritasium.[2] A December 2014 video, explaining fluid dynamics by creating a vortex in a swimming pool, was her first to get five million views.[12][10] After news coverage of Cowern winning the Flame Challenge, she was contacted by PBS Digital Studios.[10] The studio began producing Physics Girl in 2015, when the channel had about 35 videos and 125 thousand subscribers. The channel became Cowern's full-time job.[13] That year, she participated in a conference organized by the U.S. News & World Report in San Diego.[7][11]
By 2017, PBS Digital Studios produced thirty-two Physics Girl videos per year.[6][14] The channel featured ArcAttack in a 2016 video about electromagnets[15] and Rodney Mullen in a 2018 video about axes of rotation in skateboarding tricks.[16] Cowern hosted the 2019 Google Science Fair.[17] Cowern announced on September 25, 2020, that her channel was ending its partnership with the PBS.[dc 3] A 2021 series of Physics Girl videos, sponsored by Toyota, demonstrated a hydrogen fuel cell car and discussed renewable energy. By 2022, she was one of the most-subscribed science communicators on YouTube.[18]
Style
Physics Girl is about physical phenomena in everyday life.[9][4] The videos have an eccentric, informal style.[5] The channel has covered topics including curveballs and creating a cloud with one's mouth, as well as higher-level physics concepts.[4][7][9] It also has an AP Physics exam review series.[18] People who have appeared on the channel include science communicator Bill Nye, YouTube CEO Susan Wojcicki, and skateboarder Tony Hawk.[9] Cowern's videos are edited with frequent jump cuts;[19] she told Nature in 2018 that her videos took up to a week to make and that she made fast-paced videos because "they can click away at any moment."[13]
Cowern has said her goals are to give children an interest in physics and to show underrepresented groups such as women in science.[7][9] According to media scholar Nicholas Qyll, Cowern is part of "a new generation of self-confident scientists who use entertaining communication of scientific topics on social media to reach and give lasting inspiration to an increasingly large audience".[20]
Awards and honors
In 2018, Cowern won a Webby Award for Best Web Personality.[21] The following year, she was listed in Forbes 30 under 30 in the category of education.[9][22] The asteroid 21943 Diannacowern, previously designated as 1999 VG114, was named on March 17, 2025, in recognition of her contributions to science communication.[23]
Personal life
In May 2022, Cowern announced that she had recently married.[dc 4] Cowern developed long COVID in July 2022.[dc 5] She was hospitalized in March 2023 as her symptoms similar to myalgic encephalomyelitis/chronic fatigue syndrome continued to worsen.[dc 6][dc 7] She became unable to move and stayed at home with her husband as her caretaker. Cowern's sister created a donation fund.[24] In a January 2025 YouTube video, Cowern said that she is able to stand on her own for short periods of time.[dc 8]
