The Physics of Space Battles

This is a treatise of how combat might happen in space taking into account orbital mechanics among other things. I am not sure where I found it, it mentions SF so probably on one of the other SF fan sites out there. It is written by <span style="line-height: 115%; font-family: 'Helvetica','sans-serif'; color: black; font-size: 9pt"><em>Joseph Shoer Ph.D an aerospace engineer. </em><font size="2" face="Verdana">Subjects discussed include: technology, weapons, combat spacecraft designs, and how an old comic got it right.</font></span>
