The 2020s will sort current anomalies in fundamental physics into discoveries or phantoms, says Ben Allanach.
Read article 'Who ordered all of that?'
Explaining the bizarre pattern of fermion types and masses has led theorists to explore complex symmetry groups, with recent work suggesting that the “flavour scale” could be at a much lower energ...

In 1997, Juan Maldacena conjectured a deep relationship between gravity and quantum field theory.
Read article 'Redeeming the role of mathematics'
Graham Farmelo’s new book sheds light on the current debate on the role of mathematics in theoretical physics, says CERN's former head of theory, Wolfgang Lerche.

The meeting was sponsored by the Humboldt Foundation, based in Bonn, whose mission is to promote cooperation between scientists in Germany and elsewhere.
Read article 'Topological avatars of new physics'
A field configuration is topologically non-trivial if it exhibits the topology of a “mathematical knot” in some space, real or otherwise.
