hutchphd said:Are you saying that alpha changes iff e2 changes ?
No. I am saying that ##\alpha## doesn't change at all. You can "change" the value of ##e## or ##h## or ##c## by choosing different units. However, you can only pick two of those values by choosing units; once you've picked two, the third value is forced by the fact that ##\alpha## has to stay the same.
