The Stefan-Boltzmann constant (also Stefan's constant), denoted with a Greek letter sigma σ, is a derivable physical constant, the constant of proportionality between the total energy radiated per unit surface area of a black body in unit time and the fourth power of the thermodynamic temperature, as per the Stefan-Boltzmann law.
Its value is 5.670 400(40) × 10-8 J s-1 m-2 K-4.

Oh, that sucker! One of the interesting thing was our professor in China used to have a habbit to use the constant to torture us in calculating the black body temperature, say the sun's surface temprature, the warp engine's core temperature. After filling tons of miserable equations with such "σ"s, we usually ended up with a ridiculous result we don't even believe!
Hi, Vince, you graduated in system, didn't you?:lookaroun I was in Aerospace![]()

Indeed I graduated in systems ... so please don't bully me with your advanced thermodynamics knowledge!
On the other hand, I can hold my own when it comes to astrophysics, string theories and hence warp core principles~
Say, are you interested in going to the sidewalk astro at Chapeters@Ogilvie this sunday?
