BOOKS & ARTS COMMENT Books in brief

MOOCs and Their Afterlives Edited by Elizabeth Losh University of Chicago Press (2017) Whither MOOCs — the massive open online courses that promised to vastly scale up access to higher education? This multi-author volume reveals a bumpy evolution, from wrangles over “educational monoculture” to the emergence of spin-offs such as POOCs (participatory open online courses). Media theorist Elizabeth Losh is typically insightful. She argues that if we forget the long US tradition of open learning through efforts such as the Chautauqua adult- education movement and the Tuskegee Institute Movable School, we are likely to “romanticize novelty” and cramp innovation.

Planet Hunters: The Search for Extraterrestrial Life Lucas Ellerbroek (Translated by Andy Brown) Reaktion (2017) In this delightful scientific chronicle of humanity’s quest for “other worlds”, astronomer Lucas Ellerbroek mixes memoir, history and meetings with remarkable planet hunters. The field’s roots are speculative: mathematician Christiaan Huygens’s 1698 best-seller Cosmotheoros, for instance, posited intelligent extraterrestrial life.
