The Second Law of Thermodynamics requires that everything always is trending toward entropy. We plunge towards the random and chaotic. Entropy points the arrow of time in just one direction, and we will not return here. For us, the Conquering Heroes entered battle and valiantly arose victorious, and now the parade is literally over and we face a long offseason. Already the Message Board demands to know what next year will provide. We ask how long we can enjoy this feeling while we already feel i...

Yes, that is a minus sign, and yes

 

The Stefan-Boltzmann Law in physics enables us to determine not only the outward radiative flux from a body at a certain temperature, but also the maximum equilibrium temperature that any given single source of radiation could achieve in a target. There are online calculators such as here to which you may wish to refer. If you enter one (1) for both the emissivity and the
