Light clock (クリ)
A light clock is working in a moving train. Light path of light clock is illustrated vertically (in books). But this light clock leans somewhat to the right. So, to an observer stands on the ground, zigzag of the light path (saw-tooth like) warps. Two kinds of time dilation ? And if two clocks work, and if these lean differs ?
