Vacuum is primarily measured by its absolute pressure, but a complete characterization requires further parameters, such as temperature and chemical composition. One of the most important parameters is the mean free path (MFP) of residual gases, which indicates the average distance that molecules will travel between collisions with each other.
Dyson’s reputation for producing vacuums with epic suction has made the brand a household name. Its lightweight, cordless Dyson Cyclone V10 Absolute is a fan favorite — a powerhouse of a stick ...

Dyson series. In scattering theory, a part of mathematical physics, the Dyson series, formulated by Freeman Dyson, is a perturbative expansion of the time evolution operator in the interaction picture. Each term can be represented by a sum of Feynman diagrams. This series diverges asymptotically, but in quantum electrodynamics (QED) at the ...
