For a fixed point in the moving frame k, the corresponding point in the stationary frame K will have an x = const + vt and is dependent upon time t, whereas x' = x - vt = const isn't. ============================================== In Einstein's paper, where no "const" is mentioned, � 4. Physical Meaning of the Equations Obtained in Respect to Moving Rigid Bodies and Moving Clocks "Between the quantities x, t, and tau, which refer to the position of the clock, we have, evidently, x=vt" Since vt = x/t * t , x = x*1 (big deal) and x is not dependent upon time. However, computing the integral of v.dt, we are aware the result is x plus a constant. All this means the length x' is a constant, the coordinate x' moves in the K-frame but remains fixed in the k-frame. The coordinate 0' = 0-vt also moves in the K-frame. In everyday terms, the velocity of the back of the bus (0') is v when the velocity of the front of the bus (x') is v (simultaneously!) and the length of the bus is constant. The back of the bus (0') cannot be at the bus stop (0) if the front of the bus (x') is at the bus stop (0), the front of the bus (x') has a different coordinate to the back of the bus (0'). Einstein is hopelessly confused by the constant length x' and the coordinate x' which is the front of the bus and moves along the road as he shines his light up and down the length of the bus (x'-0'). This is proven by the dork's attempt to differentiate tau(x',0,0, t+ x'/(c-v)) which he claims is @tau/@x' + 1/(c-v) * @tau/@t He is differentiating tau with respect to a coordinate (ridiculous) and time tau with respect to time t (legitimate, but equal to 1).
