Me veseli . Zame je bila posebno zanimiva naslednja trditev o temperaturi:
key insight was that absolute temperature is nothing more than energy per molecular degree of freedom. This suggests that Clausius ratio between absorbed energy and absolute temperature is nothing more than the number of molecular degrees of freedom.

Mene pa so fascinirale naslednje domislice:
Ignorance can spread and grow, but it can't disappear. That's all there is to the much celebrated second law.
The famous second law of thermodynamics. The law that according to famous astronomer Arthur Eddington holds a supreme position amongst all laws of physics.
Is it all that simple? Yes it is. In an infinitely expandable reversible universe observing stones falling in ponds and causing their surfaces to ripple, but never witnessing ripples on a pond throwing out a stone, is in essence no weirder than observing only downward motion in a harmonic accelerator.
Slika prikazuje nadomestno shemo kondenzatorja pri nizkih frekvencah, ki jo sestavlja vzporedna vezava idealnega kondenzatorja (brez izgub) in upora (ta predstavlja vse izgube). Izgubni faktor je ponazorjen v kazalčnem diagramu kot razmerje med tokom skozi upor (U/R) in tokom skozi kondenzator U/(1/wC).
