A proof of the constancy of the velocity of light (1913)
Can someone please explain the argument in easier terms?<p>I am stuck here itself:<p>&gt;&gt; Then from the law of motion of the star we can derive an equation:
&gt;&gt; u=f(t-t0)<p>The function &#x27;f&#x27; is not specified.  What is it and how is it derived from the laws of motion?<p>Also, what really is tau-0?  It is the time at which light from a stationary star at the same distance would have reached the observer, or alternatively is the time under Lorentz&#x2F;Einstein&#x27;s theory.  However, what meaning is that holding in the said argument.
