Physics World magazine issue including analysis of Stephen Hawking's last work on the black hole information paradox

Physics World: Planetary Science: Secrets of the solar system, volume 29, No.7, July 2016. A post-it marks the page with an article on Stephen Hawking's latest research on the black hole information paradox with Malcolm Perry and Andrew Strominger.

While most magazines in Stephen Hawking's office dating after 2015 are transient, this one contains an article explaining the latest published research by Stephen Hawking on the black hole information paradox problem with Malcolm Perry and Andrew Strominger. In this research they coined the term 'soft hair'.

Most of the journals and magazines in Stephen Hawking's office were transient items, which would have entered upon publication, and gradually circulated out in a relatively short time frame. The vast majority of such items in the office date from the last years of Stephen's life, from 2015 onwards, and haphazardly reflect on subscriptions, affiliations and societies where he happened to be most active at that moment in time.
