I made a mistake in: "D is medium dependent" I correct it to: "D is medium independent"

Hi, D=εE, and E=Q/(4πεr^2). We may suppose generally that, E is inverse proportional to permittivity. Combining the interpretation to the first equation, E is dependent variable, and D is the independent variable. That is, D is medium dependent. Anyway, E is dependent on the permittivity...
