But let me give an example about what I mean: the equation E=m*c² uses variables and those have a valid interpretation in physics as attributes of physical systems. The term 'E' - for instance - means energy. But physicists had to say, what is the system, the term is an attribute of. (what they don't do) In fact meant is the radioactive decay, where a ray is emitted from a radioactive sample. The ray has a certain energy, while the sample looses some mass. So far so good. But this would require a different equation: E_ray = - delta (m_sample) * c² Instead the term 'E' is not an attribute of something anymore, but a 'thing' itself. This shall be equal to inertia times c squared. And that is ***** ... TH
