If an > electron moves from rest at the origin of co-ordinates of the system K > along the axis of X under the action of an electrostatic force X, ..." Is this your translation? Is "the axis of X" what is normally called the x-axis in English? Maybe you could quote it in German so that someone who knows more German than I do can comment. Anyway, I agree that calling the abscissa axis the x-axis is not ideal, but it's very commonly done. In that case X is not a variable. > > I disliked already the used of 'force' for electrical field strength. > > But anyhow... > > 'X' is here the x-component of the electric field-strength vector and > called 'X' > > 'X' is also the name of the x-axis of system K. > > Therefore we have twice the symbol 'X' in the same sentence (actually > also in the same line), but with two different meanings. > > It is not really wrong, but VERY bad writing style. > > At least Einstein could have made different types of symbols > distinguishable by attributes like italic or bold fonts. > > > TH -- athel -- biochemist, not a physicist, but detector of crackpots
