Life and Chemical Engg

Ironically the only subject i loved in my engg was the one everyone seemed to hate. somehow. i mean Chemical Engineering Thermodynamics.

There are two fundamental concepts in Thermodynamics. they are equilibrium and entropy.

lets define both in a very simple manner;

equilibrium is a state in which a body does not a have a tendency to move on either side on which forces are acting on it. some level of order prevails.

entropy is the degree of randomness of a system. disorderliness.

the chemical funda is that a system at equilibrium will tend to have a low level of entropy. entropy is basically a waste of energy.

just a thought abt entropy. most ppl say that u need passion to do a task well. which is a very wrong notion. atleast Swami Vivekananda says so. and i completely agree ( well, he is a genius, there is no point of my agreeing or disagreeing with him). this is so because, passion is a feeling. feelings means energy is spent and dissipated on them. so loss of energy does not result in good work. all that is needed is focus. less of excitement. silence. concentration. stillness. peace. that will only deliver results.

coming back to our discussion, from definitions of equilibrium , it seems as though equilibrium will decrease entropy. atleast thats the impression i get.

the contradiction

lets look at life. Mr. A is unemployed. he finally gets a nice job. i mean good pay, job roles etc. initially he was desperate for a job. after he got the job, there was an expectation or desire level.
so i can say he was at level 1 initially. his expectation from the job causes his mental state to desire a higher state level 2. as he works on, his state changes continuously from level 1 to level 2. when he reaches level 2 we can say that he has reached an equilibrium wrt to this expectation levels.

now this equilibrium brings a stagnation. he feels unsatisfied. the feelings start showing up. the entropy of his mental system starts to increase.

so equilibrium is infact leading to entropy.

remember the equilibrium is also in the mental system and the entropy is also in the mental system.
isn't that funny?

i dont think there is a flaw in my reasoning.

anyway floor is open to debate.

correct. it is a progressive vicious circle.

I don agree!!
What useful work can be done with water..It needs to be heated to become steam to be able to do some useful work.. There is a basic amount of energy tat all of us need to have to able to trigger any action at all..

Sleep is a state of least entropy..

Prob we should try and minimize that minimum energy required.
I believe that passion is a must..
thats like the triggering force ( even if some energy gets wasted in all the excitement and worries)

If there is a way to keep the drive and also not get excited ,well and good.Prob tats wat Swami Vivekananda meant !!!

@ anu,

din get u. i am slow at grasping things. where did i contradict myself? or where do u contradict me. if u can exactly specify.....

@ harini,

ur logic (reg passion, triggering etc) is very sound. i dont deny. but i strongly feel it is theoretical. and i wrote what i experienced. infact just two days back.

okay. i will try with an example. u must be on ur B.Tech project. u must hv started with a lot of passion. how was the progress initially. slowly the passion must have reduced ( again my surmise). but u wd have become more focussed. i dont know. it happends in this way in most cases. i might still be hopelessly wrong. but do analyse.

or give urself some time. analyse all ur activities for the next few months. take enough samples and test. passion lessens focus. atleast i am convinced. passion is an emotion. emotion means excited state. it will be for lesser duration. then it will come to its ground state ( the most stable).first u need to know where ur feet is. then only u can think of placing ur feet is elsewhere. that is why it is told that ppl shd not make major decisions when they are emotional.

i dont know still if i am making sense. but this is a deeper debate. which cannot be addressed in a blog so easily.

1.I agree that a calm mind works better than an excited one ( high entropy as u say).
My only reasoning is that a basic triggering force is essential.
2.As far as final year proj is concerned we work more towards the end due to deadline.
3.ya i will analyse and let to u know..

anu,

1. expectation takes place in stages. say u set a target of 75%. when u reach 75 % u will have a sense of achievement. this is ur initial equilibrium point. but this equilibrium sets off a chain of events with their own equilibrium points. u move to the next level say 80% ( say just becoz u r frnds are over u) and the chain progresses. equilibrium in prev stage provides entropy that makes u travel to next stage. and it continues. am i olarifying. well i am not sure. thats for u to figure out. but i will be happy if u substantiate.


2. reply to harini

passion is not emotion? hmmmmm....okay for ur sake, i just dropped into dictionary.com and thesaures.com. see the links:

http://dictionary.reference.com/search?q=passion

http://thesaurus.reference.com/search?q=passion

chk out the meaning / definition for urself.

actually there is no need for dictionary.com. i tht it was obvious. ( it is ) .

just close ur eyes and repeat the word passion over and over. u will understand what passion is :))

(and probably get passionate as well;)
