A senior scientist who said physics “was invented and built by men” has been suspended with immediate effect from working with Cern.
Prof Alessandro Strumia of Pisa University made the comments in a presentation organised by the European nuclear research centre.
Cern issued a statement on Monday suspending Prof Strumia pending an investigation.
It states his presentation was “unacceptable”.
“Cern always strives to carry out its scientific mission in a peaceful and inclusive environment,” the statement reads, calling the presentation “contrary to the Cern Code of Conduct”.
The organisation says it was “unfortunate” the views of the scientist, who works at a collaborating university, “risks overshadowing the important message and achievements of the event”.
