Now let us show how rapidity transforms under Lorentz boosts parallel to the zaxis. Start with Equation 6 and perform a Lorentz boost on E=cand p z y0 = 1 2 ln E=c pz+ pz E=c E=c pz pz+ E=c = 1 2 ln (E=c+pz) (E=c+pz) (E=c pz)+ (E=c pz = 1 2 ln E=c+pz E=c pz q+ = 1 2 ln E+pzc E pzc + ln 1 1+ :y0 = y+ ln q 1 1+ : 1 + : 6

In 1908 Hermann Minkowski explained how the Lorentz transformation could be seen as simply a hyperbolic rotation of the spacetime coordinates, i.e., a rotation

Irreducible Sets of Matrices 9 III.4. Unitary Matrices are Exponentials of Anti-Hermitian Matrices 9 III.5. The infinitesimal Lorentz Transformation is given by: where this last term turns out to be antisymmetric (see problem 2.1) This last term could be: " A rotation of angle θ, where " A boost of rapidity η, where A Lorentz transformation is represented by a point together with an arrow, where the defines the boost direction, the boost rapidity, and the rotation following the boost. A Lorentz transformation with boost component, followed by a second Lorentz transformation with boost component, gives a combined transformation with boost component. We see that the Lorentz transformations form a group, similar to the group of rotations, with the rapidity being the (imaginary) rotation angle. First written 15 November 2004 Last revised 2 December 2019 5 Lorentz boost (x direction with rapidity ζ) where ζ (lowercase zeta) is a parameter called rapidity (many other symbols are used, including θ, ϕ, φ, η, ψ, ξ).

On |para World Heritage Encyclopedia, the aggregation of the largest Lorentz Transformation The primed frame moves with velocity v in the x direction with respect to the fixed reference frame. The reference frames coincide at t=t'=0. Rapidity Last updated May 28, 2019. In relativity, rapidity is commonly used as a measure for relativistic velocity. Mathematically, rapidity can be defined as the hyperbolic angle that differentiates two frames of reference in relative motion, each frame being associated with distance and time coordinates. components of a velocity specifying a boost.
