Entropy!!!

navidafrasiabiannavidafrasiabian CanadaPosts: 1,363 ✭✭✭✭✭
Think of this situation:
You are crossing a street and when you see that light is red, you stop!
Entropy of the whole universe always increases and that means things get more random. So, when you stand in a specific place something messy should happen somewhere to keep the entropy increasing.
Based on what I said, do you think obeying the rules make the world a better place or no matter how hard we try, someone else do its part to make the world more messy place?!

    @Paulette , please ask your husband about this! I really like to know his opinion as you said he is into science and physics.

    I have to say that I loved my short stay in Singapore where people follow rules like no jaywalking, no litter, waiting for people to get out of the metro trains. It makes life much easier when basic rules are followed rather than the disorderly rugby scrum that getting in or out the Tube or Indian metro involves!

    @navidafrasiabian my husband is mainly engaged in entropy as a mathematician, namely in transforming energy into all its forms. He mainly studies the stability problems related to the effects of heat and cold and the materials used in the right proportions depending on the purpose of a building to be built at a specific location in a particular area. He must ensure that no chaos can arise when the buildings are finished. He must therefore follow many rules of laws of nature in order to obtain a safe result.

    Dear @mheredge , now think that their behaviour is the reason of some chaos in Africa. What is your opinion?!
  • mheredgemheredge Posts: 39,678 ✭✭✭✭
    You might have a point @navidafrasiabian. Living within the rules does make it easier for things to progress in a more orderly fashion.

    Oh, when I saw this word, "Entropy", it made me reminisce of my Thermodynamics subject (one of my hatest subject). LOL. :lol:
  • mheredgemheredge Posts: 39,678 ✭✭✭✭
    I thought 'entropy' was a medical term @kindgnice!
  • kindgnicekindgnice LEO Motivator!!! Posts: 7,958 mod
    Oh nope, it is mostly used in one of the Engineering subjects (which I hate), and that's Thermodynamics. :lol: @mheredge
  • mheredgemheredge Posts: 39,678 ✭✭✭✭
    I recall fellow students at Manchester where I was studying telling me that thermodynamics was the least liked subject on their course @kindgnice.
  • PaulettePaulette Posts: 22,499 mod
    I think my husband is then an odd man out because thermodynamics was his favourite course at college @mheredge
  • mheredgemheredge Posts: 39,678 ✭✭✭✭
    Really @Paulette?! The students I remember talking to about how much they hated the subject said that they were very easily distracted during the lectures and used to think of anything other than the subject they were supposed to be listening to.

    How can they?!!! Statistical mechanics and thermodynamics are the most fascinating subjects I have ever studied.
  • mheredgemheredge Posts: 39,678 ✭✭✭✭
    Ah well,maybe you had better teachers @navidafrasiabian. I recall being told that they were most likely to have their minds on other things while sitting in thermo dynamics lectures.

    I think both things are happening at the same time. Some people are causing destruction and others are constructing things, ideas and etc. I believe, the entropy concept is not limited to Physics, am I right @navidafrasiabian ?
  • navidafrasiabiannavidafrasiabian CanadaPosts: 1,363 ✭✭✭✭✭
    It is better to say that Physics is not limited to some abstract subjects. Physics is the language of god. So you are completely right. Entropy is everywhere. Actually, the law of increasing entropy in information science is the most consistent law of universe, something that scientist are sure that it can't be disproved. @inaamz

    Dear @navidafrasiabian , I don't agree that Physics is the language of god!
    Despite that my hatest subject during my bachelore study was thermodynamics ( @kindgnice ;) ), I really interested in entropy.
    Part of increasing entropy, I think, is our desperate shortage of our knowledge about universe, maybe our rules take part in this process.

    Wow! You have lots of friends Marianne! :) @mheredge

    We had the same hatest subject, which is the Thermodynamics. There's only one topic I liked the most from the subtopics of this subject and that was heat transfer. Can you still remember our lectures about heat transfer? It's like Q=mcΔT from which m represents mass, c as specific heat and ΔT as a change in temperature. Geez, I like solving heat transfer problems before. :) @Arvin
  • ArvinArvin Posts: 84 ✭✭
    @kindgnice Absolutely, I remember that. How enjoyable problems we'd tackled through heat transfer!

    The second law of thermodynamics states that the entropy of an isolated system never decreases over time. Such systems spontaneously evolve towards a thermodynamic equilibrium which is the state with maximum entropy. Human behaviour could be related to such an analogy. Following the rules is energy consuming and does not happen spontaneously. There is always a will and self-control behind that, so the system is not isolated. and even when you follow the social rules you contribute to the total increase of the disorder in the universe while breathing, for example, to transform glucose into CO2 and H2O and energy that you are using for your activities. Or while you bite your sandwich to smaller pieces making the system (sandwich) more disordered. All in all, you are increasing the total entropy of the universe either following human rules or not.

    Could we say, @science24, that whenever any forms of energy is converted into heat the entropy increases ?
    Maybe that's too semplicistic an idea, but it's what I remember from my thermodinamic studies though, if my memory doesn't fail me.
    It's been long time ago, but I loved thermodinamics, although I had to struggle with all the maths involved in it.
    Especially I was amazed at learning that, by studying the heat flow you could understand what direction a chemical reaction could spontaneously go: the one which led to the products containing minor energy, being propelled by dissipation of part of it into heat and probably entropy too.

    I think that obeying the rules doesn't necessarily makes the world a better place to live in: it depends on the rule. The fact the rules are generally democratically set and enforced don't prove they are likely to make ours the best world ever.
    Take for instance tens of diesel vehicles stuck in a line.
    All those motorists are certainly obeying the rules.
    Apparently they aren't contributing to make the world a messier world.
    Therefore, if a cyclist passes the line of cars, you could think he's mostly to blame for the increase in entropy.
    After all, the idling diesel engines aren't moving, completely following and complying with societal rules.
    The most likely reality, though, is that the anticonformist cyclist, the one who broke the mainstream rules, was the least contributor to pollution, entropy, and, alone, flew the flag of a possible cleanest growth.

    Come to France @filauzio. I think here people believe the rules are there for breaking a lot of the time.
