Excitement grows about the Event Horizon Telescope, physics of bent rulers, could you be the next director general of CERN? 

05 Apr 2019 Hamish Johnston

Here at Physics World we are getting very excited about an upcoming announcement from astronomers working on the Event Horizon Telescope, which will be made on 10 April. The aim of the telescope is to take the first image of a black hole, so fingers crossed!

To whet your appetite, you can watch the above video of astrophysicist Avery Broderick who explains how the telescope (which is really several telescopes worldwide) works. There is much more about the Event Horizon Telescope in the feature article “Portrait of a black hole” by Tushna Commissariat.

For something a little more down to earth, there is a fascinating paper in Physics Education called “The curve shape of a bent ruler—analytical, numerical and experimental studies”. It is a comprehensive theoretical, numerical and experimental study of how rulers bend by Anders Johansson, who is an adult education teacher in Sweden. “The experimental investigations, the algebraical expressions and the numerical simulations can be useful in high school teaching and at undergraduate university level,” he writes in the abstract of his paper.

Could you be the next director-general of CERN? The world’s most famous physics lab is looking for a leader as outlined in this recruitment notice.

If you need some tips for polishing your CV, check out “Leadership required”, which offered advice to potential candidates when the job was last up for grabs in 2014. And if you get the job, here is what to expect on a typical day “A day in the life of CERN’s director-general”.
