[edit] Some math

$\dot{E} = \mathcal {E}, \mbox {with} ~ \mathcal {E} := \mathcal {Q} + \mathcal {W}$

$\dot{S} \ge \mathcal {S}, \mbox {with} ~ \mathcal {S} = \frac {\mathcal {Q}}{\theta}$

try inline $\mathcal {E}$

First aof all see (BBC 2006), but be sure to check (This) and (That) as well! And why not Hilbert & 1900 d
