In his article “The Space-time of Physics: a Kinetic Space” Zoltán Néda reveals why is there a lot of confusion concerning the space-time of modern physics. These concepts are used routinely, but if we dig in deeply, finally we have to recognize that usually our knowledge is rather superficial and limited. The logic on which space and time is constructed in physics is an interesting and enlightening story, in which light plays an import role. The space-time of physics is tailored on light, it is built by using the propagation properties of light rays. In such view, it is a kinetic space. The author presents the logic of this construction in a concise and non-technical manner, so that readers without any mathematical background can also enjoy it.
