Example Sentences
- "Meronym: twistor"
- "In another parallel universe the amplituhedron, a recent invention in quantum field theory, is a geometric form endowed with a positive Grassmannian, that is an internal arithmetical structure for the calculation of amplitudes in terms of k-planes filling up an n-dimensional space."
- "The amplituhedron is not built out of spacetime and probabilities; these properties merely arise as consequences of the jewel's geometry."
- "Scattering amplitudes that obey the laws of locality and unitarity do emerge from amplituhedra. But unlike in Feynman diagrams, the amplituhedron does not start with space-time that has these properties."
