* Pure Python with NumPy as its only dependency. This makes it easier to install.
* Vectors may be represented in a variety of coordinate systems: Cartesian, cylindrical, pseudorapidity, and any combination of these with time or proper time for Lorentz vectors. In all, there are 12 coordinate systems: {*x* - *y* vs *ρ* - *φ* in the azimuthal plane} × {*z* vs *θ* vs *η* longitudinally} × {*t* vs *τ* temporally}.
-* Uses names and conventions set by `ROOT `_'s `TLorentzVector `_ and `Math::LorentzVector `_, as well as `scikit-hep/math `_, `uproot-methods TLorentzVector `_, `henryiii/hepvector `_, and `coffea.nanoevents.methods.vector `_.

* Implemented on a variety of backends:
* pure Python objects
* `SymPy `_ vectors
