Physics World is the membership magazine of the Institute of Physics, one of the largest physical societies in the world. It is an international monthly magazine covering all areas of physics, pure and applied, and is aimed at physicists in research, industry, physics outreach, and education worldwide. Overview The magazine was launched in 1988 by IOP Publishing Ltd, under the founding editorship of Philip Campbell. The magazine is sent free to members of the Institute of Physics, who can access a digital edition of the magazine; selected articles can be read by anyone for free online. It was redesigned in September 2005 and has an audited circulation of just under 35000. The current editor is Matin Durrani. Others on the team are Michael Banks (news editor) and Tushna Commissariat and Sarah Teah (features editors). Hamish Johnston, Margaret Harris and Tami Freeman are online editors. Alongside the print and online magazine, Physics World produces films and two podcasts. The Physics World Stories podcast is hosted by Andrew Glester and is produced monthly. The Physics World Weekly podcast is hosted by James Dacey. Breakthrough of the Year The magazine makes two awards each year. These are the Physics World Breakthrough of the Year and the Physics World Book of the Year, which have both been awarded annually since 2009.
