Disorder Definition and 74 Threads

Let's say you have a very dirty small room room and a giant clean library (lots of organized books) and let's say these occupy the same number of microstates. The entropy according to this equation is the same for the library and the room. But one is more ordered than the other one. How does it...

I'm sorry for posting this thread. I know that this is not the right site to ask but my curiosity is really bothering me and I need an answer about this serious illness that I'm having right now. In these past few days, I noticed that I have this anxiety called " Chronic anxiety" and honestly I...

Note: not homework; thread moved to biology 1. Homework Statement It is not a textbook problem, but a real life scenario, as such I am not sure the solution exists. A child is born with a rare genetic condition (1 chance in a million). There is about 1/3 chance it comes from a mutation that...

Homework Statement Produce an detailed understandsing of the anatomy and function of the lymphatic system, using correct scientific terminology to explain the rationale for use of corrective treatment for lymphedema. Homework Equations N/A The Attempt at a Solution Lymphatic edema is the...

Homework Statement How does Hodgkin's lymphoma effect the "normal" function of the lymphatic system? Homework Equations N/A The Attempt at a Solution After research I have found out that HL casues lymph nodes to become inflames. I have concluded HL causes lymph fluid to get blocked at lymph...

How much correct to say entropy is always measure of disorder Is disorder always related to entropy

Entropy is often represented as a representation of disorder in a system or the amount of energy deposited as unusable in a system. What are the other perspectives about entropy?

Something I've always wondered: why do we measure the amount of disorder (entropy) rather than the amount of order? We don't measure brightness by the amount of "dark". Surely order is the thing of interest, so why don't we measure that rather than measuring the absence of it? And in...

From what I know, the law says that disorder increases over time. But, when a building is constructed the disordered bricks,cement etc. take form of the ordered building. Am I wrong or is this an exception?

Hi all, Based on a previous post on Anderson Localization, I'm posting a more general question here: given that there is substantial disorder in many systems in general (e.g., the body, or the Earth), why do we not see effects like Anderson Localization more frequently - that is, why aren't...

Hi all, Just did a little bit of (layperson) reading about Anderson localization and disorder in crystal structures. Here's my question: shouldn't all matter contribute to 'restricting' the wave function of e.g., an electron, whether it's in a crystal structure or not? That is, what's specific...

Hi. I have heard this, that entropy is often called "disorder" but _isn't really so_. And I am even more puzzled by the connection and difference between entropy from "information theory" pov and from "thermodynamic" pov. I see stuff like this...

Thinking of entropy as a measure of disorder, how do we distinguish order and disorder. Entropy should increase with time resulting in more and more disorder with the passage of time. The solar system evolved with time. Now, do we consider the formation of the solar system as getting ordered or...

Would a perfectly ordered crystal in an isolated system with no temperature be able to store information that can be used to predict the future of that system? I am asking this question with the Big Bang in mind: intuitively, it appears to me that at the beginning of the universe there should...

I have written a common app essay about my social anxiety disorder and how I overcame it and how it made me stronger but I am bit confused that whether this topic will be apt for college essay.I am thinking it might have a negative impact on my profile but I also want to write about it because...

when they mean disorder do they mean the range of velocities of the particles increasing as entropy increases? so there are larger differences between the low KE particles and the high KE particles?

How can life be compatible with the second law of thermodynamics? Here is how. Life is a self-organized system. A self-organized system is a system in which organization arises SPONTANEOUSLY, which means that the probability of the appearance of organization is large. But this means that...

Is entropy a measure of "disorder"? In textbooks I never saw a definition of entropy given in terms of a "measure of disorder", and am wondering where this idea comes from? Clausius defined it as an "equivalent measure of change", but I do not see the relation with a concept of "order" or...

Hey, I was wondering if anybody could give me a brief overview (if possible) of how weak localization differs from strong localization, and any rigorous definitions of "disorder" and "localization" (if they exist) and perhaps recommend some good papers to read on the subject. Thanks

I am seeking information regarding mental health. I am wondering if there is a mental illness, disorder, syndrome, etc. that is characterized by persistent arguing/fighting? Is there an adult version or form of the oppositional defiant disorder? Almost as if the individual is addicted to arguing...

Hi, I'm sorry and hope this forum allows people who don't study but are interested in physics to post their primitive questions: I like watching documentaries and in every documentary on physics that i watched when it came to entropy, it was simply described as disorder as if that was a...

Hello, I was diagnosed with language disorder(learning disability) since I was a kindergarten. I am having a lot of trouble with reading and writing, and also have poor communication skills when it comes to meet people in general. It also affects my schoolwork no matter what subject I'm...

In my TD classes I have to deal with entropy. But what does it really mean? I know that it is the degree of disorder and the equation S=q/t. But what is this disorder? How can a physical system be aware of order and disorder since it is an abstract concept?They say that solids have high order...

Entropy is the measure of ored and disorder. But who tells that what is order and what is disorder? Isnt it a relative or subjective thing? How to define it in general, or it can be definet only for thermodinamic systems?

I am a year three who suffer badly from bipolar disorder II, it damages me both school grades and communication skills (and honestly speaking, not training myself on these things, I have been only doing only what I want, not what I need, bad idea) . nevertheless, I like nature, I spent far...

I am convinced that order must come from disorder. If there is something to be disordered, then if there is nothing constraining things to become ordered, then it seems axiomatic that some order eventually arises. Specifically, with regard to the formation of the Observable universe from a...

Hey guys, I am curious about a condition I have had ever since I can remember. It is a short burst in hypersensitivity especially in hearing and touch. It last for up to about 2 minutes and is quite annoying. It makes every movement feel more difficult and exhausting. When I listen to music...

To show that entropy is not the same thing as disorder (what people intuitively accept as disorder) my textbook gives an example of crystallization in a supersaturated solution. And it argues that since both temprature and disorder decrease the entropy must decrease also, but it does not. Hence...

I have a very hard time learning in public education environments for the following reasons: Whenever I'm attending a class, and the teacher/professor is talking, I would block out everything around me, including but not limited to the teacher talking, most visual information (at least in...

Can a man cure a disease lacking research? I have a neurologic-visual disorder called HPPD since 1 year ago. My vision is a mess. There is no cure nor satisfatory treatment and it's lacking research. I'm 20 years old, am currently coursing engineering. I'm very intelligent and would like to...

Both Kurt Cobain and Amy Winehouse suffered from bipolar (manic-depressive) disorder. Both rocketed to international fame but died young of unnatural causes. Kurt shot himself at the peak of his career (April 5, 1994). Amy's career was largely over after winning 5 Grammy Awards in March 2008...

I understand the pedagogical concern that the idea of “disorder” should be discouraged when introducing entropy to new students (e.g. http://entropysite.oxy.edu/cracked_crutch.html). But I also just read http://www.science20.com/train_thought/blog/entropy_not_disorder-75081" by Steve...

Do you suffer from an affective disorder?? Mental illness is very though to deal with. Most people will just not understand what's going on and think that you're crazy. When you have a broken leg, then people will sympathize with you and help you. But when you have a mental illness, then people...

Folks, According to physics, the universe is expanding with increasing entropy from a state of Order to Disorder. Can this be connected with the idea of the mishaps/misfiring that occur in evolution ie dysfunctional organsims etc that we see all around us. Ie the process of going from...

The word 'cosmos' is defined as an orderly harmonious systematic universe. There are some people who actually think that disorder, randomness and chaos is a better description of the Universe, but I disagree. For the most part the Universe exhibits a very high degree of order, harmony and...

On pages 46-6 and 46-7 of Feynman Lectures, Vol 1, Feynman talks about irreversibility, order, and entropy in mechanics. He gives an example of an irreversible process: (p. 46-7) He then gives the definition of entropy as the logarithm of the number of ways in which the molecules could be...

Hi, first of all I have to say that I know practically nothing about cosmology, though I know some basic physics. The reason for this post is that while reading "A brief history of time" by S. Hawking, he mentions in some parts of the book that a lumpy universe corresponds to a disordered...

Is nostalgia a some kind of disorder? Aren't some people more prone to nostalgic thoughts, or is it that they have more time for such thoughts, or is it that from their point of view their past was more relaxed and wonderful as compared to the present period they are going through, or is it that...

Do people lose their interests when treated for bipolar disorder? Are there any other changes in the mind itself? I am worried ill lose my edge in biology courses if i begin treatment.

Hi all, I've been confused lately by the appearance that the universe is becoming more orderly and the second law of thermodynamics that states that all systems start from order and become disordered. I assume that the Big Bang was hot and disorderly and that it started to get orderly after...

For example, an increase in the entropy of the system will be exactly equal to the entropy decrease of the surroundings. So the net change in the entropy of the system and its surroundings is zero. Putting this in perspective to all the systems and environments in our universe, how is the...

Is Schizoid personality disorder "Asperger/Autism"? "Schizoid personality disorder People with SPD are seen as aloof, cold and indifferent, which causes some social problems. Most individuals diagnosed with SPD have difficulty establishing personal relationships or expressing their feelings in...

"entropy is disorder" = outmoded theory?? The wikipedia article I quote below is confusing me. I followed the links to Frank Lambert's website, where he claims that Peter Atkins, in the 8th edition of his Physical Chemistry, has come around to Lambert's idea that entropy is not related to...

Like a commenter said, who says academics don't make meaningful contributions to public life? :smile: http://bps-research-digest.blogspot.com/2010/06/does-darth-vader-meet-diagnosistic.html

Scientists say disorder is increasing? How come that we have well-orderd galaxies (from randomness) with the passage of time (many are in the process of evolution)? How come elememts have combined together to form cells and eventually living beings. How come humanbeings have started to...

Hi I read an article on this about a year ago or so which outlined the issues and the possible causes. Aside from cellphone radiation, it seemed like none of the other proposed causes had been conclusively ruled out. I'm just wondering if anyone could give me a bit of an update on this...

Hope this isn't in the wrong forum, but I couldn't quite find a place to put this. Do any of you have OCD? I think I might have it because I often engage in repetitive behaviours. I'm not satisfied with myself unless I do every question in a section and get every question correct. I find...

How does disorder (such as structure defect, doping,substitution, etc. )change superconductors' Tc?No matter what kind of superconductor it is. Is there any resent paper exactly and detailedly discussing about this question? Thanks in advance.

Hi all, I'm wanting to write a small program simulating a 1D lattice with some motion. I have the equation: m_{n}\frac{d^{2}u_{n}}{dt^{2}}= k_{n,n+1}(u_{n+1}-u_{n})+k_{n-1,n}(u_{n-1}-u_{n}) Then using a simple trial plane wave (u_{n}=Ae^{-i\omega t}). It boils down to: - \omega^{2}...

When we talk about Entropy we look at how the disorder in a system is measured. Now if we see the whole universe as a system, we can say that the universe tends to constantly go towards more disorder since it is expanding. My question is: If the universe which we live in and governs everything...
