Carlo Rovelli reports on a conference which brought together two communities that have evolved independently for many years.
In 1997, Juan Maldacena conjectured a deep relationship between gravity and quantum field theory.
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.
A field configuration is topologically non-trivial if it exhibits the topology of a “mathematical knot” in some space, real or otherwise.
We have conquered the easiest challenges in fundamental physics, says Nima Arkani-Hamed. The case for building the next major collider is now more compelling than ever.
Ideas from supersymmetry have been used to address a longstanding challenge in optics – how to suppress unwanted spatial modes that limit the beam quality of high-power lasers.
The last few years have seen an explosion of ideas concerning naturalness, but we’re only at the beginning of our understanding, says theorist Nathaniel Craig.
It is high time we addressed the low representation of women in high-energy theoretical physics, says Marika Taylor.
"People say that string theory doesn’t make predictions, but that’s simply not true."
