11. The new time axis of the observer forms an angle " ? " with the previous time axis, with. 12. However, the clock that is moving relative to the black observer marks off time along the blue time axis . 13. The new time axis of the observer forms an angle " ? " with the previous time axis , with. 14. This blue line labelled " ct " 2 may be interpreted as the time axis for the second observer. 15. Taylor's work suggested that self-stable plasmas would be a simple way to approach the problem along the confinement time axis . 16. In the quantitative trend analysis data is plotted along a time axis , so that a simple curve can be established. 17. The axes for the moving observer are not perpendicular to each other and the scale on his time axis is stretched. 18. Activities in time distance diagrams are displayed both along a time axis and along a distance axis according to their relative linear position. 19. A straight line connecting these two events is always the time axis of a possible observer for whom they happen at the same place. 20. The lorentz transformation is the equivalent of a rotation involving the time axis . talk ) 02 : 53, 10 July 2010 ( UTC)
