Question
When one of these operations is rotation-free, it is known as a “boost.” For 10 points each:
[10m] Name these linear operations named for a Dutch physicist that map between inertial reference frames in special relativity.
ANSWER: Lorentz transformations [or Lorentz transforms or Lorentz boosts]
[10h] In addition to vectors in spacetime, another Lorentz covariant vector is this quantity whose first component equals energy over the speed of light and whose latter three components equal the Lorentz factor times mass times velocity.
ANSWER: four-momentum [or momentum–energy or momenergy; prompt on momentum]
[10e] The Lorentz factor is denoted with this letter. This letter names the region of the electromagnetic spectrum with greater energy than X-rays.
ANSWER: gamma [accept gamma rays]
