How we could discover quantum gravity without rebuilding space-time

In the search for a theory that unites general relativity and quantum physics, many have tried to rethink space-time. But what if space-time emerges naturally, like a hologram?

Why we must inspire people with the magic of condensed matter physics

Condensed matter is a huge field of physics that gets less attention than it deserves. We must show people its subtle magic if we are to draw in a diverse set of researchers for the next generation, says Felix Flicker
