Janna Levin on Extra Dimensions, Time Travel, and How to Overcome Boots in the Face | Brought to you by Allform and LinkedIn Jobs. “I used to resent obstacles along the path, thinking, ‘If only that hadn’t happened life would be so good.’ Then I suddenly realized, life is the obstacles. There is no underlying path.” — Janna Levin Janna Levin (@jannalevin) is the Tow Professor of Physics and Astronomy at Barnard College of Columbia University. She has contributed to an understanding of black holes, the cosmology of extra dimensions, and gravitational waves in the shape of spacetime. Janna is also director of sciences at Pioneer Works, a cultural center dedicated to experimentation, education, and production across disciplines, as well as Pioneer Works’ virtual home The Broadcast. Janna’s books include How the Universe Got Its Spots and the novel A Madman Dreams of Turing Machines, which won the PEN/Bingham Prize. In 2012, she was the recipient of a Guggenheim Fellowship, a grant awarded to those “who have demonstrated exceptional capacity for productive scholarship.” Her last book, Black Hole Blues and Other Songs from Outer Space, is the inside story on the discovery of the century: the sound of spacetime ringing from the collision of two black holes over a billion years ago. Her new book, Black Hole Survival Guide, is scheduled for publication near the end of 2020. Please enjoy!
