u
velocity
u
velocity of a tachyon
U
total energy of an oscillating particle
U A , U B , U V , U 1 ,...clocks
v, v o

Notice that in this book we use γ for the square root, γ =
1 − v 2 /c 2 , and
not for the inverse quantity. This is in accordance with the previous German text “Grenzgeschwindigkeiten und ihre Paradoxa”, Springer Fachmedien
Wiesbaden 1996.
