Stephen Hawking, who died on 14 March at the age of 76, was the physicist the whole world knew. But what exactly were his key scientific achievements? Out now in print and digital format, the May 2018 issue of Physics World examines Hawking’s scientific legacy through the eyes of Seth Lloyd from the Massachusetts institute of Technology, who knew the great man and includes some of his favourite Hawking anecdotes too. It’s an unmissable article that you can also read online here.
Elsewhere, you can discover the eight most promising wearable technologies for monitoring your health and find out why research into the mysteries of liquids could help us know what’s going on at high pressures inside planets like Jupiter.
Plus learn about the upcoming International Day of Light on 16 May, explore working in the Paralympics “pit lane” in this month’s Lateral Thoughts article, and find out what life’s like as a PhD physicist with a career at NASA’s Jet Propulsion Laboratory in California.
