What are the differences between net, network, mesh and grid? If I have a look at the OED entries, I have a feeling of rather a circular definition: mesh Material made of a network of wire or thread... net A piece of open-meshed material... grid A network of lines that cross each other... Could you list some most common collocations with each of the words and explain why this particular one is used? Such as why do we use mosquito net and not mosquito mesh? | 1 |
Astroturfing is a word used to describe a fake or counterfeit grassroots campaign. The clever term is derived from the notion that one kind of fake grass is astroturf. Another more niche example is from mathematics. We call the "germ" of a function the part at the bottom of a stalk in some sheaf. We call this a germ because it is like the germ for the stalk of a plant. In both of these examples, one makes an analogy to create a term, and then related terms, carry on this analogy to build terms related to the first. Is there a specific name for this sort of term? | 1 |
There is always a debate around Earth Hour every year, and the opposite side of Earth Hour usually claims that The (sudden) decrease and increase of the power usage in the start and end of Earth Hour will cause much more power loss (than the save of power), and even do damage to the power supply system. Is this statement true? To what extent? Thank you very much. | 1 |
I'm currently working on some graph theory, and I'm checking the robustness of graphs, by removing random vertices from a graph and then check how many vertices are outside the giant component. Then I'll do that for a lot of vertices, and plot them using ListPlot. This takes along time to calculate, is there a way I can visualise it, that it plots something everytime a value is calculated. thisFunctionTakesVeryLongAndReturnsAList := .... ListPlot[thisFunctionTakesVeryLongAndReturnsAList [graph]] thisFunctionTakesVeryLongAndReturnsAList calculates a value that can be plotted all the time | 1 |
If two stick two magnets the mass will be less than sum of the individual magnets. They lose certain mass while they stick together. Probably, they release some energy. My question is: when the magnets are separated, whether their original mass is restored to its original level? If that is right then after performing sticking and separating several times of the two magnets, they should vanish. | 1 |
Possibly two questions in here: Are these sentence constructions logical, and if they are, why are they different? I swam across the Ocmulgee River. I swam across the Pacific Ocean. I swam across the Red Sea. I swam across Lake Winnipeg. I can't think of a way of phrasing the lake example while using an article with a proper noun. I thought at first it was because Lake Winnipeg is different; it's generic portion (the "Lake") comes first and the name of that body comes second, but I swam across Falls Lake is the same. Yet the sentence I swam across the lake sounds right to me. ...Why? | 1 |
There is a similar question that gives a bit of an explanation, but little mathematical proof here: force applied not on the center of mass I would like mathematical proof that shows that the velocity of a rigid body when a force is applied to the center of mass is equal to the velocity of the same rigid body when the same force is applied to a point on the body other than the center of mass. Thanks in advance! | 1 |
Via Cantor's back-and-forth method we know that the linearly ordered set of all rational numbers and the linearly ordered set of all real algebraic numbers are isomorphic. But from the point of view of what people usually do with rational numbers or with algebraic numbers, the order isomorphisms yielded by Cantor's proof are icky. Are there any that are well behaved and have nice mathematical properties? | 1 |
Okay, so recently I ended up saying this: Well, that is unfortunate... sometimes it happens, sometimes it doesn't. Okay. You know, just saying "Sometimes it happens" already tells you that something happens sometimes and other times it doesn't. But, sometimes, I need to make very clear that this "something" doesn't happen always. That's why I say sometimes it happens, sometimes it doesn't But is there a way to shorten this phrase? To make it simpler, but still making very clear the fact that this "something" may not happen? Repeating "sometimes" is not very much of my liking... | 1 |
There are many businesses that hosts other related or unrelated business as part of their service. Example a plaza/shopping mall will have various stores, owned and operated by others, a university may host other organisations such as book stores, restaurants, computer stores etc. The University of Technology, Jamaica has an organisation/business called the Technology Innovation Centre (TIC), that is a business incubator. TIC itself hosts various businesses not relating to the University. All these hosted businesses uses the address and name of their host as part of their own address.What name is given to these type of businesses that play hosts to other businesses? | 1 |
I have a forum where you can Like a reply. After you press that button it changes from Like to Liked. Now I want to add a Dislike button so I would like to replace the "Liked" text for something that would also include "Disliked". I think the word should be close to something like "Done", "Voted", or "Pressed" but also related with the original text. Do you have any suggestions? | 1 |
I am working on displaying source code for which I pass a path to a macro. Now I am wondering if it is possible using xstring or stringstrings to match from after the last delimiter, i.e. / to the end of the string to determine the filename. Example: I might pass ../code/subfolder/project/code.java to the macro for which I want to extract the substring code.java. It seems easy to match the first occurrence of a character, but not the last. | 1 |
I am aware that the universally accepted style is to put an apostrophe-s at the end of the second possessor's name. Example: Amy and Steve's car My question is not whether that is the common rule; I know it is. My question is whether anyone knows of a style guide, grammar, or other authority that condones writing this in the usual style of a plural possessor; that is, with an apostrophe on the end of the compound/plural owner's name: John and Jacks' house John Merrill, Stephen Arthur, Chuck Williams, and Donald Smiths' law firm Thanks! | 1 |
In photography the negative means the lightest areas of the photographed subject appear darkest and the darkest areas appear lightest. But I was wondering: is this the way how negative should actually be described at all? What if the negative just meant that you reverse the (visible) spectrum. What kind of image would that produce? Would the whites still be whites? (unlike in the "traditional" negative where white -> black) | 1 |
In order to answer a question I have to take a look at a document that is not with me by the time that question was raised. Which of these sentences is more suitable to express that idea? I am not able to answer your question without taking a look at document X; I cannot answer your question before taking a look at document X; Feel free to suggest any other sentence that you may think appropriate. | 1 |
The dispersion of white light beam while passing through a triangular prism is well known. Considering the reversibility of optical path, it should be possible to reverse the experiment. How can one implement the reverse experiment of lights' dispersion in experiment? What are the necessary and sufficient conditions of the incident light beam(s) in order to obtain a white light beam after passing through a dispersive prism? For example, can one remove some of light beams with specific wavelengths or adjust their intensity but still obtains white light beam? | 1 |
In my understanding, Alternating Direction Method for Multipliers (ADMM) is widely viewed as a tool to parallelize large-scale convex-optimization problems arising in statistics and other related fields. The following paper by S. Boyd is a good reference https://web.stanford.edu/~boyd/papers/pdf/admm_distr_stats.pdf But one can also use, like Help needed to define a constraint in an optimization problem?, ADMM to solve non-convex problems I am looking for a paper that I can cite when ADMM is used for solving otherwise non-convex problems? | 1 |
Initialisms are pronounced as words and acronyms are spelt letters. However, some words sound the same, said and spelt. e.g. Input Output can be abbreviated as IO. It can be spelt I-O or pronounced Io as in the moon/god. There is no way to tell the difference in how it is said or written. Is a word which is pronounced the way it is spelt, an initialism, an acronym or both? | 1 |
The plural of 'passerby' is 'passersby' with an 's' acting like an infix (W-B says that this is the only plural form of the word). This seems like a very interesting exception, so I thought I would ask a question. Are there any other English words that are made plural by an 's' put inside the noun? One criterion has to be met: the singular noun is composed of one (unhyphenated) word only. | 1 |
A customer want to place his gold to bank account. He shows up in a bank with his gold bars and says that he wants to put it to his gold account. I was unable to choose the correct word here. Customer delivers his precious metal bullion to the bank. Customer leaves his precious metal bullion in the bank. Customer gives up his precious metal bullion to the bank. Customer leaves out his precious metal bullion to the bank. Customer leaves his precious metal bullion to the bank. Customer submits his precious metal bullion to the bank. Customer puts away precious metal bullion to the bank. Customer ... precious metal bullion to the bank. Which word should I choose? | 1 |
I am confused about some definitions in logic/ axiomatic set theory: We stated in our logic lecture the ZFC axioms and called the members of a ZFC-model "sets". But to define formulas and structures, we needed sets as in "A structure is a non-empty set with functions and relations" and also for formulas, we needed, e. g. a variable set. Could you help me solving my problem? For me it currently seems circle-reasoning. Best regards | 1 |
A toy is randomly put in a given Cereal box as a promotional gift. There can be N different types of toys and each one can be of any type N (IID). (a) Find the expected number of cereal box one has to buy before she can have atleast one toy of each type, (b) If she has already collected m toys, what is the expected number of different toys she has collected. Can someone explain how to model this problem using Indicator Random variables. | 1 |
"Gas prices are going up." Which of the following is also a general statement about gas prices: The price of gasoline is going up. The gas price is going up. And could you tell me why? I have this question because although I know, for example, both "Tigers are big" and "The tiger is big" are generic constructions, but I am not sure how to use "the" when it is a noun phrase instead of a single noun. | 1 |
This is going to sound stupid but anyways. I am currently in a physics class and my teacher likes us to use dimensional analysis which I do not understand how to use or what to do with it! So firstly can someone explain that? And secondly, I can do all of the work (my way) and show all the work and my units, he just doesn't know "how I did it" but I still get the right answer and have all the work stated and he docks points for this, is that at all fair? Any opinions from other teachers would be greatly valued here. | 1 |
I'm using in hopes that in the following sentence. However, it does not seems to be formal and appropriate for a scientific paper. Is there any similar phrase that has the same meaning but more formal ? Thanks. To overcome this crucial issue, a popular solution has been used where a task is assigned to many workers and the results for this task are aggregated in hopes that the aggregated result is actually the correct one. | 1 |
I have a PDF document, evidently produced using LaTeX, which has wide white margins and crop marks. I'd like to remove these margins and corresponding crop marks. Is there a tool to do it automatically? EDIT Werner suggested to use pdfpages package to include PDF's pages in a LaTeX document. I should actually include only the pages of the PDF I'd like to crop and use options to trim it. I'm waiting for an help in recognizing the most appropriate options to do so. | 1 |
Is there a word that describes the case of using an adjective to describe a noun that already suggests as much? Examples the pretty model won all of the awards the smart genius answered every question the dangerous monster ate the man the fast jet the floating buoy Some of these examples might not be the best, but I hope they give the right idea. I know they are superfluous, but I'm not trying to define the adjectives themselves, but the act of using them. | 1 |
With How do I change color settings in TeXStudio? and How can I set a dark theme in TeXstudio? I managed to change the colour of the editor (in this case to a darker theme to prevent eye strain). Now I would like to change the colour of The toolbars The Structure and Message / Log File menus The line numbers at the left of the editor The Line, Visual column, Text column counter below the editor I already tried the advanced options from Options -> Configure TeXstudio. | 1 |
I have observed while driving at night the yellow marks on road seem white. What I understand is the color of an object is the visible light wavelengths it does not absorb. In other words the yellow line does not absorb yellow light. The head light of my car is normal and thus is slight yellow light. So from my understanding the color of the line should not really change and still be yellow. Can somebody confirm the same observation (or is something wrong with my eyes) and tell me the reason. | 1 |
On points arranged in a parallelogram lattice, like on the image in this Wikipedia article, how to calculate the maximal distance any point on the plane may have to its closest point from the lattice. Or alternately, the maximal radius of a disk that can be placed on the plane such that it does not contain any point of the lattice. As input I have the side length and both diagonals of one possible parallelogram that fits the lattice. Edit: I meant the lattice not grid, i.e. only the sparse set of intersection points of a parallelogram grid. | 1 |
As you see in the picture, the blonde woman is kicking another woman in the stomach. Can the blonde woman say: Take my kick. (I mean that she wants to give her kick to another woman and she humorously offers the other woman to receive her kick) And what is your opinion about this picture? Can the African woman say: Take my punch. If these sentences are not correct, what would a native speaker suggest? Thank you . | 1 |
I am in search of a word that has the meaning of 'capacity of a person to habituate to a new environment'. I can use adaptability. Like he is more adaptable than others. But 'adaptable' may not necessarily imply to a place, it may imply adapting emotions also. So is there any word that signifies the capability of a person who habituates to a new environment quickly. f I call it X. I can say as. He is Xer than others. | 1 |
I've just saw in Maclane and Moerdijik's book ("Sheaves in Geometry and Logic: A First Introduction to Topos Theory") about the Cohen forcing viewed in a categorical way using Topos theory. Is there any reference for forcing techniques using categories and Topos? Can the other kinds of forcing (iterated, Prickry, etc.) be viewed in the same (analogous) way? Any reference for the last question? Thanks in advance. | 1 |
Many intuitive knot invariants including Jones' polynomial are inspired by statistical mechanics. Further profound connections have been explored between knot theory and statistical mechanics. I was looking if similar connection have been found for graph invariants. I am interested to know if any attempts have been made form statistical physics community to solve graph isomorphism problem. Since both knot problem and graph isomorphism are problem about testing structural equivalence there might be connection between them. | 1 |
I was reading linear vector spaces. When doing some exercise to prove some statements based on the properties defined for linear vector spaces, i suddenly noticed, outside the things defined, i'm using a common notion without proof. This notion also surfaced when i was studying Group theory. After giving a thought i come to the conclusion that i've used it in all systems which are modeled after euclid. I mean first i give some postulates. Then i derive statements from those postulates. Euclid also has it as "common notion" : If equals are added to equals, the wholes are equal. So i started wondering that if anybody challenged this or attempted to build a system without this. | 1 |
If the explanation for the B-field due to a current in a wire that I've heard (length contraction by moving electrons in conductor) is true, would you really need to be moving to feel the "B-field" of this wire? What I mean is, if the electrons within the conductor are moving quickly enough, then they will already be (barely) length-contracted along their path. Since there is no "moving positive-charge", as electrons are the only charges that are moving, wouldn't this length-contraction of electrons immediately come off as an increase in negative-charge density? | 1 |
I'm interested in quantum mechanics book that uses high level mathematics (not only the usual functional analysis and the theory of generalised functions but the theory of pseudodifferential operators etc, certainly the modern mathematics). If there isn't something similar please give me a reference to the book that is strictly supported by mathematics (given a set of mathematically descripted axioms author develops the theory using mathematics as a main tool). | 1 |
In this Phys.SE answer Ron Maimon stats: there is no relativistic particle formalism in which the particles have postive energies and casual propagation. You can either deal with fields in which case the particle notion is non local or you can deal with particles. But then they go back in time. Is this true that there can be no particle interpretation where particles only travel forward in time? I'm not asking about path intergrals but the particle interpretation in general, I'm also aware the field interpretation is the more popular. | 1 |
We easily find probabilities by counting the number of ways we can meet a condition and dividing it by the number of total possible outcomes. This is using combinatorics to solve probabilities. Im looking for a scenario, or a type of complicated combinatorial problem, in which the approach at counting the number of ways of meeting a condition is actually easier by multiplying the probability of meeting the condition (determined in other ways) by the total possible number of outcomes. I realize this may be an absurd question, but its been in the back of my mind for some time. Can anyone imagine up such a problem? This is for the sake of education, so that we may all learn of new problem solving techniques. | 1 |
What is wind? I think it is kind of a vibration of air particles. If so, is it a longitudinal or a transverse wave? Or is it just a bunch of air particles being pushed? Smells disperse in wind so the latter explanation might be a better. And breath also consists of movement of air particles. But how can wind travel so far without stopping? Can it be the pressure produced by temperature difference pushing it? So could you say it can be attributed to a wave? Any help would be appreciated, thank you. | 1 |
I've read it can be due to 'intrinsic semiconductor conduction' and surface conduction. The LED I am looking at is InAs, which is apparently prone to surface conduction. I have tried out what these two quantities are on google but have been unsuccessful. In particular because I have no extensive mathematical knowledge of the subject, and so am looking for a qualitative answer. And why does reverse leakage current increase with higher temperatures? | 1 |
Q: Is the italicised verb form correct in this sentence? Jane's pale face suggested she could be ill: her parents suggested that she have a medical examination. A: The sentence is grammatically correct. The subjunctive remains in force even though it is likely the patient will follow the doctor's advice. To actualize the blood test with "has" would be telling an untruth. The subjunctive holds the notion of a suggestion in place. Thus does grammar make its own modest contribution to truthful speaking. I don't see how this sentence can be grammatical. Please could you offer any comments. | 1 |
I am just about to create my beamer file for my upcoming presentation in which I need to open another program (NetLogo if it helps) to show it to the audience. Is there any possibility to create a shortcut or link so that I only have to press 'next' or click on that shortcut to open the program? Or do I have to close the PDF my self and open the other program? I'd be most thankful for your answers. | 1 |
I am sure all of us have played with rubbing things and producing static electricity and when I was charging my comb by rubbing it on my hair and watching it attracting a small piece of paper, I heard a very feeble noise just like an electric buzz sound. I could feel the electron "cloud" all around the comb and the paper it I could find no reason as to why a sound should be produced. From where is that sound coming from? | 1 |
This is a historical question partly, and maybe too broad for this site, but would require some familiarity with modern physics research practice so hopefully appropriate here. Einstein's later years, after general relativity, were (as I understand it) taken up predominantly by his effort to find a unified theory that explains both gravitation and electromagnetism and their interrelation. And from what I understand his approach was mainly mathematical, trying variations of functions and so forth, looking for something that fit - and doing his work predominantly on paper. Had he access to modern computers - programming languages, mathematica, etc. - how might that have changed his progress, and willingness to give up perhaps? And in what ways have computers in general changed / revolutionized theoretical & mathematical physics? | 1 |
Lately, I have been watching sparks while connecting my electronic devices and I can notice that electricity is kind of blue, and theoretically it's blue because it reflects blue wavelengths?? And that makes it a particle (like if I said that light is a particle because photons). So am I correct? If electricity doesn't have that color because of that, then why is it blue?? After asking this now I think the following questions: Does electricity have the exact temperature to produce blue light (in terms of the EM spectrum)?? If the answer is no, why does electricity have color?? | 1 |
If context is needed, I'm happy to supply it.. The sentence I want to rephrase: Some selection of this kind has for some time been imperatively called for, by the wants of the gardener, farmer, and amateur, the multiplicity of sorts in the larger works and catalogues rendering them nearly useless to those who merely wish to know those kind adapted for family or market supply. I'm at a loss of words for interpreting the sentence into concise rephrasing for elementary comprehension. It's from a book by Robert Buist titled "The Family Kitchen Gardener" (Full book). The sentence is under PREFACE a few paragraphs down. | 1 |
According to Wikipedia, A set of states C is a communicating class if every pair of states in C communicates with each other. A communicating class is closed if the probability of leaving the class is zero. Would you call an absorbing state a closed communicating class since it cannot be left and it communicates with itself? However, one problem with calling an absorbing state a closed communicating class is that since it consists of only one state (obviously) - and this might not satisfy the definition of a set of states. | 1 |
English has a "intricate" relationship between graphemes and phonemes,i.e. there is no sure way of knowing how to pronounce something by just looking at its written form. Generally any language has this property, but English is much more complicated in comparison to - say - Italian (which happens to be my native language). This fact is known, and I remember stumbling upon a very nice sentence by an English Author, who leverage on this fact and wrote a sentence whose words did not make any sense together, but if you read them, then the "sounds" formed a perfectly meaningful phrase. I seem to remember something concerning "god" and a "fish"? Not sure though. Anybody remember that? | 1 |
In a research problem in an unrelated area, me and a student found it necessary to count the number of directed graphs with every vertex having one outward-pointing edge, with no restrictions on the number of edges pointing inward. Not being a graph theorist, I was wondering if this is a well-known class of directed graphs. Is the number of such graphs for fixed n known? If it is unknown or an open problem, we'll work on it together, but it seems likely to be known. | 1 |
I am writing an ad and would like to write: "Our team of economists are at your service and available by phone or email. They will be happy to respond...". I know that grammatically speaking, 'team' is the subject of the sentence and, being singular, would dictate that 'it' is "at your service". BUT, it just feels better reading this and it evokes a picture of a bunch of economists doing what they do rather than a single unit". Is what I'm doing OK? Should I be arrested by the grammar police? | 1 |
Possible Duplicate: Temporarily increase line spacing I tried to follow these examples here Temporarily increase line spacing but in my case it didn't change anything. I have to use a latex template, which is provided by my university. My title looks currently like this: as you can see, the third line has not enough spacing. Can anyone help me to fix this issue?

Does a first-person possessive pronoun have to come last if it is in a list with others?" "My irresponsible sister loves jewelry, so she took both Sally's and mine.

Does a magnetic field have concentrations of magnetic force lines as seen when putting iron filings over top a bar magnet or are these imaginary? I.e. are they just an artifact of the iron being a 'conductor' of the magnetic field lines making them look like they are concentrated along these path lines but are really continuum of strength around the bar magnet when there are no filings are present? Also I learned that field lines do not cross, yet there are magnet configurations who's forces are explained as the magnetic force vectors are indeed crossing and are additive such as a Halbach Magnet Array. So what is actually happening here? | 1 |
In an airplane, the lady attending you is known as the attendant, besides sometimes being called a stewardess or air hostess. What does she do? Just serve you. Then what is that my maid does? Nothing but serve me. Can I therefore call my maid, my attendant? What about my other servant? Can I call him my attendant too, since I cannot call a male person my maid? Is gender the only difference? Then who and what are pages? I am looking for a clear distinction between these four terms. | 1 |
So I asked a question earlier similar to this, and the solution made sense; however, the graph was very simple with only five vertices. If the graph is more complex like this one then how would you determine if the graph is a bipartite? When I asked earlier, I was shown the method of trying different color combinations for all the vertices, and checking if the edges connected opposite vertices that way, but is there another way to do it for a more complex graph like this one? | 1 |
I do understand the concept of Naive Bayesian classification, as it tries to calculate the probability of an outcome of a class given multiple evidences. It comes from the Bayes theorem and it is called naive as it tries to each of piece of evidence as independent. This approach is why this is called naive Bayes. However, I wonder why in the derivation of the mathematics behind Naive Bayesian Classificaiton, we take logs and odds. So my question is basically the following: Why odds and log odds transformations are meaningful ? | 1 |
I would like to understand the first law of thermodynamics, but I have some problems with the basic concept. How to define exactly the internal energy? As I see it, given a system of particles, which the principle of work is in force for. Can it be considered 'per definitionem' the isolated thermodynamical system? If yes, the diatermic system can be defined as a system where the priciple of work isn't met. Therefore, if we define the internal energy as the sum of kinetic and potential energies of the particles, there is a term missing from the equation of the sum-work in diatermic case, called heat, which the first law postulates. How can heat be mathematically characterized? | 1 |

The function of behaviour is an important theme of evolution. Should either in or of be favoured in the above sentences? | 1 |
Is there some way to produce these figures using TeX itself preferably using TikZ? If yes, then I would also like to add labels right next to the nodes rather than using a legend. This is a screenshot from a paper I am reading and I would prefer using TeX to create them than using some external tools.

Moreover, I don't know how to change the crosses to the different symbols given in the diagram drawn above. | 1 |

I don't know how to describe exactly my issue, but I'll make a try: I am writing a document on Lyx, and I am using the module "report". I have customised the page margins but when I write paragraphs, some sentences do not obey the margin and some words are not in the same line. Graphically: From a PDF that is created with Office there is a tool (a ruler I think) with which you can make the paragraphs in order to be all the words in the same line. For example: How can i fix this issue? | 1 |
Is there a word that refers to an official interest group held in school where registration is totally optional but members once registered are expected to come? Official means the school keeps records and members who do not reach a certain attendance threshold would be kicked out. I was thinking of school club but that seems to suggest that attendance is totally optional since clubs have the notion of come-and-go-whenever-you-like. On the other hand, the word association or organization sound too business-like. Besides school club, is there a better word that has a closer meaning to official school interest group? | 1 |
I have the following figure: As of now I create this in Word/Powerpoint and paste the screenshot in a LaTeX file. Is there a way to create this natively? Also, what would be the advantage of doing so? The tables are just place holders and actual table design/content may change. But I prefer if it could be editable and not fixed. I'm not sure I even know where to start or how to go about it. I've never needed to draw anything in LaTeX before. | 1 |
By my current understanding of the two words, the sentence: The preciseness of this precision is very definite is grammatically correct. Correct me if I'm wrong, and if so; what is the distinction between the two words? OED definition of preciseness: Exactness, accuracy; definiteness; minuteness. OED definition of precision: a. An instance of exactness or preciseness; a particular, nicety, minute detail, esp. of language. b. The fact, condition, or quality of being precise; exactness, accuracy. Also, what is the word for the situation in which this can occur? (I want to say it's the opposite of an oxymoron?) | 1 |
I did the best I could. The sentence above can be rephrased: I did the best that I could. In these two examples (that) I could is a relative clause. However, I am not sure whether it is modifying best or the best or an ellipted element. What exactly is this clause modifying? Secondly, what type of phrase is the best here and what type of word is best? | 1 |
Humour me for a minute here and let's imagine that all interesting and plausible supersymmetry models have been "cornered" out by the experimental data; what sort of alternatives are there for having quantum field theories with Poincare symmetry that are allowed to have nontrivial internal symmetries? i.e: that the Coleman-Mandula theorem does not apply? What other assumptions of the theorem can be relaxed or dropped, and still leave us with workable QFT? Are we forced to drop full Lorentz-Poincare symmetry or will the theorem still apply with slight violations of that symmetry? | 1 |
How does one go about creating a TiKz library (is it even possible)? Is this a formidable task for a beginner? As a chemical engineer, I would very much like to have a library to create a process flow diagram, like the one below, in which you place nodes with certain shapes and connect them based on specific ports. Update: I actually found out that there are a couple of libraries for this purpose: chemplants PIDcircutTikZ | 1 |
We observe in static electricity experiments that a comb rubbed on dry hair lifts tiny pieces of paper.This is due to the attraction force exerted by the charge collecting on the surface of the comb on the opposite charges collecting on the hair.This is a very small amount of force.But our body is always exerting gravitational force on all objects around it.Still it cannot draw such tiny pieces of papers.Why? | 1 |
Non-unital completely positive (CP) maps take a maximally mixed quantum state (aka a normalized identity matrix aka an infinite temperature state) and map it to something else. This necessarily decreases its von Neumann entropy and, depending on how you define it, reduces its temperature. Can a stronger connection be made between thermodynamics and CP maps? To what extent do non-unital CP maps reliably cool states that aren't infinite temperature? | 1 |
Layperson here. In a theoretical big crunch with space contracting faster than the speed of light, would information be travelling faster than speed of light? Because the points A and B themselves would be moving towards each other FTL. Maybe this is obvious or I have made a wrong assumption. Either way, please answer. Also, forgive if this has already been asked. I did search and couldn't find such a question. | 1 |
Precision is usually understood as the number of significant figures in some experiment. Accuracy is the difference between the best measurement and the real value. How are precision and accuracy determined from a given experiment? Or equivalently, how are systematical errors and statistical errors calculated. Statistical errors are usually treated approaching "the normal distribution". But I am not sure how systematics are determined...Perhaps making some "pattern" measurements? | 1 |
The Centroid point (at intersection of medians) divides a planar triangle into three equal-area smaller triangles. In case of spherical triangle, the three geodesics joining the vertex to the midpoint of the opposite side of spherical triangle intersect at a (Centroid-like) common point. But, when geodesic is constructed to join this Centroid-like point to the three vertices, the resultant smaller spherical triangles do not have equal area! A different geometrical method or a formula for implementing the exact division of spherical triangle into three equal-area spherical triangles could not be found in literature. | 1 |
My question is very simple. I just would like to know what do they mean by: "I believe you're up" I've heard this expression in a movie and here is the script: I already met your dad. He loves me. Love is very strong word. Well, he at least likes me, right? We're busy tomorrow night. Okay, and we're back. Amy, I believe you're up. Oh, oh. Okay, I got this. | 1 |
Our company uses project management software called Jira. In Jira you can mark one issue so that it 'escalades' another, or 'is escaladed' by another. I think that is something like 'cause', but you can set 'cause' or 'is caused', so they are different. And I find the meme 'that escalated quickly', and looks like it has a similar meaning to escalade. Can anyone tell me what escalade means in 'one issue escalades another'? Can I use escalate instead? | 1 |
Some concepts are just too difficult to be fully understood. Take for example the multivariate causes of the recent recession: who among us can honestly say that he or she grasps the situation completely? With respect to topics like this, although it is not possible to thoroughly grasp the concept, attempts can be made to elucidate--at least partially--the more mysterious parts. Accordingly, is there a phrase that means, "To make less mysterious, but not explain completely because the concept is too difficult"? | 1 |
The hotter something is glowing the more white/blue it appears. A dying medium sized star expands, cools and becomes a red giant for a while, but eventually it is going to gravitationally collapse (once enough Iron (Fe) is accumulated in the core). Then it blows the outer layers away and what is left collapses into a white dwarf. What makes the dwarf shine? and why is it white? Does the luminosity decreases as the object cools down, or is there some other reaction that keeps it glowing for a long time? Can a white dwarf turn brown or black never to be seen again? Do all white dwarfs turn into Neutron stars eventually? | 1 |
I recently heard about the possibility of the creation of a "baby" universe or "pocket" universe from our space time,the theory says that concentrating enough mass into a tiny volume of space (like in black holes) a pocket of false vacuum would form e perhaps it'll continue to expand following it's own inflation period and go on forever completly disconnected from our space time without influencing it any way. Now my question is : supposing that we live in a metastable vacuum we know that true vacuum bubble could form via quantum tunnelling and begin to expand into our space time where these false vacuum bubble (or pocket/baby universe) are supposed to go and expand ? | 1 |
Possible Duplicates: Salutation in an Email How do you greet multiple recipients in an e-mail? How do I use the initial words while writing an e-mail, in particular, to my superiors? Suppose somebody is writing a letter to the HR representative of a company, requesting a letter, approval, information, etc. Should the salutation be written like: Hi or: Dear or her/his name: Dear Jenny Are any of these proper way? Or, should I leave it blank and start with the crux of the matter right away? Does it matter whether I know the person or not, or if the person is not my superior but is a colleague or junior? | 1 |
According to the work of J. Scott Carter you can draw pictures of knotted surfaces in four-space in several different ways. I know the man is a real artist in this, but did anybody come across some software that does this for you ? See for example: http://www.jscottcarter.com/) I guess you can figure out a parametric equation for a knotted sphere, and pay a trip to Mathematica-land, but I haven't done this. This is probably a more specialized version of Topology software) | 1 |
I'm looking for a positive word or phrase - though ideally, a single word - that suggests that old dubious beliefs are being re-examined and questioned. "Self-doubt", has a negative connotation and I would like this to indicate a sort of personal growth. For example, it could describe someone who used to be paranoid and believe that everyone was conspiring against them learning to become more trusting. | 1 |
In this problem are only truth tellers and liars. When meeting two people, A and B, you ask A: "Is any of you a truth teller?", to which A replies: "If B is a liars, then i'm a liar" What are A and B? What I got so far is: If A is telling the truth, then the statement must be true when B is telling the truth, and false when B is lying. If A is lying, then the statement must be true when B is telling the truth, and false when he is lying. I can't seem to find a way to logically formulate this, and I'm thinking this might be because I'm missing something. Have I got it right? | 1 |
A colleague once disparaged his own research to me by saying that it didn't involve any sort of cohomology. It does, in fact, seem like homological ideas appear across disciplines...and are considered to be mathematically "sexy". I wonder what the deep reason for this is? (The answer "because these ideas prove many things" seems cheap, or ad-hoc here.) Where can I find a "bird's eye" modern view of general homology/cohomology? | 1 |
I'm writing a thesis and would like to have the pages on which a new chapter start look fancier than they currently do. I like the example on this page: how can I create a chapter heading like this? However, since the abstract is defined in the preamble, it appears the same in each chapter. Obviously, different chapters need different abstracts and I don't know how to correct this? Secondly, for some reason, the contents of this preamble are changing the font style of the rest of my document and I'd like the bulk of what I'm writing (outside of chapter title and abstract) to stay in the standard font that LaTeX uses. Thanks for any help. | 1 |
I asked a similar question on SciComp, but it is a little out of the domain, so I thought I'd give it a try here as well. Give n points, I would like to place them in a periodic box (periodic such that the distance between two points "wraps around" to the other side) so that the minimum distance between any two points is as large as it can possibly be. How do I do this? I imagine analytically this could be quite difficult, but is there at least a numerical procedure? | 1 |
The sentence is: "Since they were first invented, we have advanced, and designed stylish glasses for people whose vision need to be corrected." I've been told that the verb needs to be "need" and also that it needs to be "needs". Need: The argument is that the need refers to "people's need" and therefore by implication refers to a plural group, i.e. people need ... Here the antecedent is considered "people" ... Needs: The argument is that the need refers to "vision", i.e. singular ... Here the antecedent is considered "vision" ... Which one is grammatically correct? | 1 |
I'm trying to dive under this incredible world of non-WYSIWYG. So, for my first main challenge I need to write my master's thesis with LaTeX. And I found some difficulties at the very beginning of my work: the cover page. I need to customize the cover page like this model (it's the mandatory model for our thesis in my university): I need the university logo to be within the dotted retangle. I tried to fit it there without success. | 1 |
In class my prof said that when showing a system is at equilibrium it suffices to show that the moment at one point is zero. Why? Why does showing the moment at a point is zero imply the moment of the whole system is zero? If I misunderstood him and the statement above isn't true, how do you show the system is at moment equilibrium at all points of the system? You obviously can't show the moment is at equilibrium for infinite points individually. | 1 |
To me, that means: I can start dreaming after buying a lotto ticket. This is weird because without the lotto ticket, I can have my day-dream anyway. Shouldn't this be something like "your chance to realize your dream has arrived"? This slogan kind of gives me the opposite feeling about buying a lotto ticket, as if it is always nothing more than a day-dream to win the lottery. | 1 |
A human ear responds to a wide range of frequencies. My teacher already has said me, when you are speaking about a part of your body that it belongs to it- it is not artificial et cetera- you must say the following: the eye the ear . . et cetera. But, I just have seen the above sentence. Would anybody kindly elaborate it? Many thanks | 1 |
A variation of "smother", obviously, to describe someone with an inclination to smother other people. "You're just too needy and smothersome." Thoughts? Corrections? Suggestions? Edit: Apologies and clarification. I did find a Google search result that states that this word is an adjective which describes something that is easily smothered. But to me, this word sounds akin to "bothersome": causing bother, troublesome. To me, "smothersome" wouldn't describe something that is easily smothered, instead it would describe something that does the smothering... | 1 |
I am getting familiar with some basics ins probability theory and I have a question concerning moment-generating functions and characteristic functions. The following is cited from Wikipedia: A key problem with moment-generating functions is that moments and the moment-generating function may not exist, as the integrals need not converge absolutely. By contrast, the characteristic function always exists (because it is the integral of a bounded function on a space of finite measure), and thus may be used instead Is there a connection between the following two facts? the characteristic function is (real) analytic moments of all order exist Furthermore I have one question in mind somehow: If a distribution has a characteristic function that is analytic, is the distribution then moment-determinate? | 1 |
I came across a shop selling the fruit jam that my sister had been looking for. But the fruit jam came in apple and peach flavours, I was not very sure which one my sister liked better, so I decided to buy both. Now, given that situation, I want to explain why I bought both apple-flavoured and peach-flavoured jams to my sister: I bought two fruit jams in different flavours because the jams would be sold out. I could not [take any chances / take any chance] . Thank you Kitty | 1 |
I want a word for a person who accepts advice of others. Basically, I am reading a play and in that there is a ruler who accepts the wise advice of others. What word can be used to describe such a person? Example : That man is indeed __________ since he imbibes the noble qualities of the wise by the accepting their advices. Please provide a reference sentence with your answer. | 1 |
Is there any particular problem or scenario where quantum logic may be applied? If so, what is the benefit of using quantum logic instead of classical logic? I've been reading quite a lot on this topic but it still seems like pure theoretic considerations to me. If there is so much effort put into forming new type of logic based on quantum mechanics, are there any practical uses of this type of logic? | 1 |
Earlier I asked this question. So, similarly, imagine the same type of list with elements having a guest and probability of attending, but now each guest also has an age. How can we calculate the expected average age of the guests of the wedding? I can heuristically group the guests into age ranges and then compute the expected number of people in each age range, but this doesn't tell me the expected mean. | 1 |
Hi I am very new to this aspect of physics and I am having trouble with the derivation of the Rayleigh-Jeans from the steps shown at the hyperphysics web site. I have emailed Dr. Rod Nave who is listed as the person-in-charge at the site but it appears there is no one at that email perhaps. It would really be much appreciated if anyone can have a look at the uploaded image file here and follow the queries I make on them. | 1 |
Following the measurement of gravitational waves, many sources described them and explained they carry energy away. What I don't get is how this energy will get transfered back to anything else. If the fabric of space-time itself is vibrating, it would seem to be in impossible for any physical object to gain this energy. What am I missing? How would one hypothetically get energy out of gravitational waves? If impossible, does the universe end up with nothing but GW? | 1 |
