Well, whoever said thermodynamics is only applicable for engineering?
Of course its applicable to many fields in engineering like mechanics,
chemical, materials even biotech!!Of course its all the same 3 laws
but i suppose the profs apply them in different ways!
I've actually done the same course under three different names
each as useless as the previous though getting progressively tougher.
Well here i've some really wierd proofs for stuff having nothing to do
with engineering.I've been unable to disprove them !
And the consequences of these proofs being true is mind boggling!!
The first. This actually came to me in the middle of a phone conversation
with a friend.Very spontanious but though i've thought about it for hours
later i still can't disprove it.See there's been so much debate on whether
the universe is infinite or is it finite. Now what is the definition of infinity??
A number n is defined to have a limit infinity if for
all x e N , n > x. So is the universe infinite or not? Well , there are so many
bodies in the universe, each having mass and hence entropy. If the
universe were infinite, the entropy of the universe would also be infinite.
But by the second law del s>0 for the universe! But by definition of infinity
it can't exsist!! So obviously our assumption that the universe is infinte is
not valid.So what does this imply?? That the universe has an end,
a boundary. What lies beyond it?? Well no one knows for certain,
but i suppose many theories could be evolved.Just like when we thought
the earth was flat! Which reminds me. There are some people who
extinguish this exciting thought of an universe with a boundary by saying it
has more than 3 spacial dimensions and hence loops around itself, just like
the earth is for 2d. Finite, yet boundary less!
The other proof involves death and ghosts ( more on that later). Now i suppose its
safe to assume that ghosts have more entropy than living beings given that they can
fly and scare people. And just living beings have more entropy then inactive dead
things. Now, in case of "spontanious" death, del g< 0. But i've never
heard of death being exothermic, so obviously it must be a rection with positive
entropy change. Hence ghosts (or something like them) should exsist!!!
Spooky huh???
