Quantum field theory (QFT) provides a comprehensive framework for describing the fundamental interactions of matter and radiation. In the context of atom‐field interactions, QFT elucidates how atoms ...

Mathematicians have struggled to understand the moduli space of graphs. A new paper uses tools from physics to peek inside. “That’s a super hard problem. It’s amazing they were able to,” said Dan ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you wanted to answer the question of what's truly fundamental in ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball rolling in ...

Edward Witten reflects on the meaning of dualities in physics and math, emergent space-time, and the pursuit of a complete description of nature. Among the brilliant theorists cloistered in the quiet ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it’s also the most successful, in terms of sheer predictive power. Simply by following the math of quantum mechanics, ...
