Second law violation? Let\'s ask Matt (Introduction)

the violation of the second law of the thermodynamics can be shown by radiation heat transfer between two surface through curved mirror.It is explained on web page hsoylu.wordpress.com.-Halil,-This is a purely theoretical treatment, akin to Maxwell's Demon.-The damning statement comes during the problem definition here:
"Two surfaces of it have emissivity equal one ε=1 (perfect
absorber) and later two surfaces are perfect reflectors that emit no radiation
ε=0."-There are no instances where such devices have ever been built, because in order to get a "perfect absorber" you would need to acheive the operational temperature of Absolute Zero. As our universe has never reached that temperature (and won't for several billion years) this setup has no practical value on the question of breaking the law of thermodynamics--especially when taking into consideration the fact that neither life nor the Sun are perfectly reflective & absorptive surfaces.-That said, it is an interesting thought experiment!

\"It is, brahmin, because of attachment to views, adherence to views, fixation on views, addiction to views, obsession with views, holding firmly to views that ascetics fight with ascetics.\"
