Scaramucci: He doesn’t have any cards when it comes to President Xi. Remember when he came down from like Orange Moses with the tablets and the tariffs. And people looked at that in China and said, well, match those. And they kept ratcheting up. And then the president realized, wait a minute, I'm going to lose this economic trade war. And so he called a truce.

Scalars carry zero indices as lone values a. Vectors gain one as vᵢ packing n components into a column. Matrices take two as Mᵢⱼ filling m×n grids. 3-tensors use three as Aᵢⱼₖ arranging m×n×p entries in cubes. 4-tensors add four as Bᵢⱼₖₗ holding m×n×p×q values in hypercubes. Structural engineers feed the elasticity 4-tensor into finite-element codes that predict how steel beams twist and yield under seismic shear in high-rise frames.
