I am attempting to write a personal statement at the beginning of a resume and am having a quandry as to how to write the following: I am a super hero with seven years' experience in blowing out fires with my exhalation... I assume that since the experience doesn't belong to the seven instances of years, this is incorrect use of the plural possessive. How can I write this statement properly? | 1 |
I'm working with algorithms that filter their input (that is, remove part of it), and I'm not sure this phrase is unambiguous: This function returns the filtered elements. Is it obvious that filtered here means the elements that have passed the filter? Or could it mean the elements that have been filtered out? If both are present, I believe it's easier to eliminate the ambiguity: This function returns a pair of lists (filtered_out,filtered_in) . This function returns a pair of lists (filtered_out,filtrate). Buf if I see just a variable named filtered, without the _out and _in suffixes, I'm not sure which one should be inferred. | 1 |
Is the matrix that we get from diagonalization the only possible diagonal matrix that can be transformed from say matrix A? Assuming that A is diagonalizable? I think it is but I don't know how to prove it? The way I look at diagonalization now is that it is an algorithm but I am not sure if the matrix that we get from it is the only diagonal matrix that we can transform from A. Can someone please explain to me. Thanks. | 1 |
The game of Go is... or The game of go is... Apparently the International Go Federation capitalizes it. Its dictionary entry doesn't appear to be (from what I have seen). It seems to fit the definition of a proper noun as it isn't preceded by an article (such as "the" or "an"). So which is it? Also, where does that put checkers, chess, basketball, football, etc. They are never (or at least not regularly) capitalized, yet they seem to have the same characteristics. I predict the argument is going to be that Monopoly is capitalized because it is a brand and go should not be capitalized since it is not a brand and it is not referring to a specific instance of anything. Is that correct? | 1 |
I'm studying the first chapter of Hartshorne's Algebraic Geometry by myself and I found this book really hard for a beginner like me, but my advisor said to me that I had to study Algebraic Geometry by this book during my vacations. Then any part of the Hartshorne's book which I find very dry or superficial I search the same subject in another books or notes available online which are easier to read and have more exemples. Then my question is where I can find more material of this concept of dimension and height explained in this page of Hartshorne's book: Thanks in advance. | 1 |
Legolas prodded him across the bridge ("You'll beg for mercy, but you'll get none from me, oho no!"), up the beech-lined path ("You'll never work in this country again, I'll bloody well see to that!") Source. What's the meaning of the expression "I'll bloody well see to that!"? It means something like "I'll make sure of that!" I am not sure what it really means. | 1 |
A sometimes online sparring partner of mine recently wrote: Men (as opposed to women) have had a purpose that should serve us well should this new transhuman world ever actually materialize: We provide; we protect; we invent; we drive the engine of economies. Normally, I wouldn't separate the items in a series after a colon with semicolons unless one or more of them included a comma of its own. But here the items are independent clauses, which makes me think that semicolons should be used, regardless. So, what's correct? | 1 |
Einstein in his derivation of special relativity came upon the equivalence of energy and matter, and given the right circumstances, the relation can go either way - matter can become energy, and energy can become matter - right? So my question relates to the second process - energy becoming matter. While I know energy does not literally condense into matter in the sense that steam condenses into water, by analogy does the (rather loose) saying: "matter is essentially condensed energy" have any merit? | 1 |
Why is it that supergravity is an extension to general relativity? In what ways? What I have read until now says the following: GR got itself concerned with gravity after the revolution of special relativity. Then supersymmetry was a plausible new theory and after the investment of supersymmetry in general relativity, supergravity was born. Thus, this chain tells us that Sugra is an extension of GR. If this is right, I don't think this is the only way to explain it, is it? How can I technically understand how this is true? | 1 |
I would like to know more about the idiom "to get going" especially in the meaning "to depart", I mostly use it to mean "get started" but I've heard that it has very many other meanings. Is "get going" in the following sentence an idiom or not: We should get the car going soon or else we'll be late. Side question, where does this idiom come from? | 1 |
I was wondering how precise the location of an object in a Lagrange point needs to be to maintain stability, since it seems that several natural objects (asteroids) exists together in some of these locations, and also space missions that have sent spacecraft to them have overlapped in time. As part of the same question I wonder how close to each other these spacecraft are at this points. I assume that in real life Lagrange points are not really points (mathematically), but there is a margin to them? I believe that some of the points are not that stable and require spacecraft to make adjustments. Maybe this control capability also helps them be together at these locations? | 1 |
I've noticed this paper which explains that they have observed the "Hawking radiation" emitted by a black hole analog. In which sense the Bose-Einstein condensate described by the paper can be considered a black hole analog? It is essentialy that the "analog of an event horizon" for sound waves is created or are there other relevant aspects? And what has been observed which mimics Hawking radiation? Is there something in this experimental observation that can only be explained by quantum effects, such as phonons? | 1 |
I am studying graphs through an online course and came across the idea of a "connected component", a "subgraph in which any two vertices are connected to each other by paths, and which is connected to no additional vertices in the subgraph." This means that a single graph need not be connected. So my question is: what, if not connectivity, defines a graph and separates it from another graph? And as an aside, if there is no such boundary, is it ever useful to think of all graphs being connected? | 1 |
I guess I can call them 'politician words' but.... What do you call a word/phrase that has a lot of emotion behind it, but doesn't necessarily have any specific meaning. E.G.: Freedom, Liberty, Terrorism, Patriotism, etc. Speech words doesn't quite get it. Rhetorical dynamite words? Nahh. Sending vague messages to your medulla oblongata to scare you into voting for me is highly accurate, if unwieldy. | 1 |
I used to make my presentation with PowerPoint and Keynote which both were easy but this LaTeX is driving me crazy since you should add anything you want in a hard way! In fact, I have tried to search about different types of effect I can use for LaTeX presentation but I was not successful to find many. Is there anyone knows a good source, different effect command, etc.? | 1 |
So recently in the blog post on tetration, it talked about tetration with nice clean powers (calling them these because I don't know the right term). But how does it work when given a complex power? How about a decimal power? Or even just a negative power? And one final yet somewhat unrelated question: can you use some sort of method to reverse tetration by using tetration? | 1 |
It's often convenient to add line numbers to a page automatically and the lineno package generally does the trick. But I've had two problems with it It doesn't seem to align the line numbers with the actual text lines - linenumbers drift between lines and occasionally skip lines as well as a consequence. Sequences of equations get skipped. Now I've seen this work properly in other PDFs and so was wondering if there's some magic option I'm missing. All I do is include the package and then turn line numbering on. | 1 |
Negative probabilities are naturally found in the Wigner function (both the original and its discrete variants), the Klein paradox (where it is an artifact of using a one-particle theory) and the Klein-Gordon equation. Is a general treatment of such quasi-probability distributions, besides naively using 'legit' probabilistic formulas? For example, is there a theory saying which measurements are allowed, so to screen negative probabilities? Additionally, is there an intuition behind negative probabilities? | 1 |
I'm reading Jerome K. Jerome's 'Three men in a boat' The above is about fishermen's bluff. My question is in the above paragraph a man knocks ashes (from his pipe) against the bars. But what is bars? On the counter? or on the window bars? But it is not likely under the circumstances, so I just wonder if 'bars' mean something different or particular meaning in this context. | 1 |
I've spent some time on Halmos' Measure Theory and must upvote such a good book. I want to solve most exercises in this book. I'm not sure whether there is a solution manual or instructor manual that can be downloaded or read online coz solutions are very important for self-study. I've tried to google it several times and results corresponding to my search were not satisfactory. | 1 |
Writing "enough" three times in such a short sentence seems too repetitive. So is there a different or more succinct way to write it? Horrible example sentence: I am drunk enough, fast enough and dumb enough that it just might work! Just removing the first and second "enough" would change the meaning, no? I am drunk, fast and dumb enough that it just might work! So can I write the sentence as follows and get across the same meaning as the example sentence or did I just come up with nonsense? I am drunk-, fast- and dumb enough that it just might work! Thank you for your replies! | 1 |
I was doing a question about resonance of sound box connecting to a tuning fork. It asks why the sound lasts for a shorter time with sound box than if the tuning fork is struck identically without the sound box. Is it because the sound box dampens the vibration of tuning fork, or because due to larger contact area of box with air the box transfers vibrational energy at higher rate to air, or these two reasons are actually the same thing? So does it mean that resonator will always dampen the driving oscillator? I'm quite confused between the idea of energy transfer in resonance and damping. Thanks in advance:) | 1 |
When I am composing a large document in LaTeX, I often compose the chapters in separate documents. When I do this I have to copy and paste a large block of header text to the chapter I am editing so I can make sure the formatting is correct while I am writing it. How can I import a header file of formatting information with a single line? | 1 |
Considering the fault of any experimental evidence from LHC for supporting the supersymmetry idea until now, can we say that it is dead? Generally the people who are working on this subject say that MSSM probably is dead but we have some new extensions of it such as NMSSM. This argument seems weird a bit. Sometimes I feel that it is a vain try to keep an idea live because they have invested their scientific life on it. On the other side, I have to confess that the supersymmetry is a beautiful idea. But it seems that the nature does not like it and we have to accept it. Other related question is, if the supersymmetry fails, can we say that the superstring fails too? | 1 |
Please tell me the meaning of stereotype in the following passage Reflexes: This is the behaviour in which movement takes place in a particular organ. This movement is very fast, stereotype, and for a short duration such as knee jerk, blinking of eyes and withdrawal of hand from a hot place". This is a behavioral science term, not sociological. Edit: Thank you everyone for the reply. Finally I got the answer from Britannica - Stereotyped response | 1 |
When someone practices something, they do it often/as a habit. When someone says something is practical, they usually mean it is pragmatic/sensible/applicable, yet not necessarily practiced. And my teachers have used practicum to refer to a test, which is an examination, not an instance of practice. What is the common root of these words, what does it mean, and why do these words seem to mean different things? | 1 |
Suppose you are given a differential equation and a set of initial conditions (or boundary conditions) pointing to a unique solution. Is there any way to know off-hand if the solution will be an even function, an odd function, or neither? This is, I suppose, tricky, because the fundamental set of solutions could include both even and odd functions (say, sine and cosine). The trick is knowing a priori that, for a given set of conditions, the constant coefficient for all of the odd solutions is zero and the constant coefficient for all (or some?) of the even functions are non-zero values. Or vice versa. Can this be done? | 1 |
Within the multicol environment I want to be able to fix a figure to be displayed at either the top or bottom of a column (as in a scientific journal). The figure environment cannot be used in multicol and I've tried using wrapfig and even creating a minipage to do this, but the figure always seems to be placed where it is inserted in the text and therefore must be moved every time an edit is made. Is there a way to force a figure to be positioned at the top or bottom of a column in multicol? | 1 |
Is there some relationship between the correlation of two random variables, and Bayes Theorem? A bit of background intuition, if W = random variable denoting number of women in a room, and L = random variable denoting number of long-haired people in the same room, we can infer about one variable given the other either using the correlation value or the conditional expectation value as given by Bayes Theorem (though Bayes deals with events, probability densities are tied to expectations anyway) Thanks | 1 |
For something to be a blackhole, it must have gravity and the radius must be smaller than the schwarzschild radius for its mass. -Electrons have gravity -Electron are theoretically believed to be infinitely small points Since it has gravity it is capable of being a black hole. Since its radius is infinitely small, it must have a schwarzschild radius and thus be a black hole. | 1 |
I have read online that light can produce a weak gravitational field (for example antiparallel beams should, in principle, attract weakly). This made me wonder if light can produce minute gravitational waves? Even if the waves were extremely weak (no disregarding of those high order terms in the applicable equation, whatever equation that may be), could the gravitational waves dissipate energy (on the order that is expected for cosmological redshifts) when light travels across cosmological distances? I was thinking about the debunked tired-light hypothesis regarding the cosmological redshift, and I wondered if anyone has considered a mechanism whereby gravitational waves dissipate energy. | 1 |
I'm deeply interested in understanding delayed choice eraser experiment. Although I understand the experimental results, the retro causality is causing a big headache. From what I understand, the hidden variables theory is a no - no, due to experimental verification of the Bells inequality... A recent PDF that I came across confused me, hence this question... The PDF claims that the superposed eigenstates will continue to evolve, if not interrupted by a detector. My question is: Can it be established that it continues to evolve despite not being measured? Doesn't that violate the Copehagen interpretation -or- is it an understanding that is implicit to the quantum processes itself? Or am I making a noob mistake? | 1 |
I'd like to quantify over all cardinalities of sets. My end goal is to make a category-theoretic arguement: For all cardinalities of sets, in the category of sets with maps as morphisms: the subclass of objects with that given cardinality is closed under the class of isomorphisms, thereby forming a subcategory, for each set cardinality, where the morphisms are isomorphisms. Can I quantify over a class that isn't a set? Is there a good way to specify this class of cardinalities? Is there a better way to go about this? | 1 |
Consider two different shaped containers having same area: one is cylinder, the other is like an inverted pyramid (roughly). Both have the same level of water, the weight of the inverted pyramidal container will therefore be greater than that of the cylinder. But I know from Pascal's law that the pressure should be same in both containers. If the base areas are the same then the force (weight as measured by a scale) should also be the same. Why are the weights different? | 1 |
I am working on size dependent surface energy of metals. I need to know the different energies between the atoms. Different papers use different energies but their meanings seem alike, therefore they confuse me a lot. The concepts I confuse are: bulk free energy, cohesive energy, Gibbs free energy, binding energy Can someone tell me the correct definitions of them and show their differences in detail? | 1 |
Usually it is said that black holes cannot have electric or magnetic dipole, only electric charge and angular momentum are allowed quantities besides mass So, it would seem that black holes behave as perfect diamagnets that don't allow field lines to enter into the event horizon? If I place a magnetic dipole pointing near an event horizon, what is the boundary condition of the magnetic field on the horizon? does the field lines flow around the event horizon perfectly? | 1 |
What is the act of making something ownerless? All I've seen is to "declare something ownerless". However, in this statement one isn't so much as announcing as he is transferring something property. Moreover, if one wants to discuss his act of transferring, it wouldn't make sense to use the word "declare" (i.e "his declaration of making this item ownerless was ineffective" sounds like a mouthful). | 1 |
I'm studying model theory nowadays, and I understand how one-sorted (classical) signatures and structures work. However I am also interested in groupoids, which can not be described as a structure for a one-sorted signature. Looking up online, I came to the notion of many-sorted signature: nLab, Wikipedia. According to nLab, these can be used to describe, for example, directed (multi-)graphs, which seems easy enough: Take sorts for edges and vertices, and source and range maps from edges to vertices. However I can't see how can we describe a signature for categories in this language. We need all the ingredients for graphs (edges=arrow, vertices=objects), and at least one function symbol for composition, but since composition is only partially defined, I don't see how this can be done. | 1 |
I'm trying to write a program that lets the user put in the center point of a circle and its radius, and the put in two points to form a rectangle. Then I'm wanting it to print out whether the if the circle is touching/inside the rectangle in any way or not. I feel that I need to know all points the circle touches in order to know if its touching the or inside the rectangle at all. Not sure if I made that completely clear, but any ideas? | 1 |
In cosmology: A comoving observer is the only observer that will perceive the universe, including the cosmic microwave background radiation, to be isotropic. (Wikipedia) According to this definition, is Earth considered as a comoving reference frame, or are we supposed to have a "peculiar velocity"? What is the current precision for measuring if a frame is comoving or not, and for measuring its peculiar velocity? Or: From which speed (with respect to Earth) a frame would be considered as peculiar? | 1 |
I have recently been studying Bayesian as well as Frequentive Statistics (mostly null hypothesis significance testing) and am confused as to the meaning of the distribution of the likelihood and observed data in both. According to my understanding, Bayesian school of though treats the distribution of the sampled data to be same as that of the likelihood of th data conditioned over the hypothesis (For example if data follows a normal distribution then the likelihood function is also normal with same mean and variance) whereas in the frequentive school, the likelihood or null distribution is basically the distribution followed by the test statistic which is different from the distribution followed by the data. Could someone explain whether my understanding is correct? | 1 |
Very simply put, if one places a block of some material on a level surface and pushes it horizontally, a certain coefficient of friction is measured. If one tightly couples an oscillator of some sort to the block such that it vibrates, a much smaller coefficient of friction is generally observed. Any explanations of this effect, with varying frequencies of oscillation? Worth noting is that the vibrating coefficient of friction is less than the normal dynamic coefficient of friction. While perhaps not more efficient energy-wise, it appears it could be a useful effect. | 1 |
Suppose a system A which is a vessel of water with two electrodes, connected by a resistor, placed in the water. If you apply voltage to the electrodes, energy is transferred from the battery (not included in system A) to system A. I read in a book that the form of energy transferred is work, and not heat. But basically what happens is that the resistor heats up and transfers heat to the water, am I wrong? | 1 |
It's strange that he should say so. She tiptoed lest the guard should hear her. It's crucial that she should have her own car. . I've seen those three sentences somewhere on the internet. I found them very unintuitive and quite deceiving, so I've been looking for the explanation, yet did not find one. If you could explain the usage of "should" in those sentences, I should be very grateful. | 1 |
I'm building a site with two main categories. One side is portfolio work, the other is written work. Among the written work, there will be personal blogs, tutorials, more in-depth articles, etc. I'm looking for a short, preferably single-word name for all of my written work. I thought about using 'writings', but it feels a bit like bad choice because it's so close to the verb to write. Does anyone have opinions on this option or suggestion for a single word? | 1 |
I am required to find a research topic in this domain, so I'm really interested in finding out what kind of problems are covered in this domain, and how others are using these techniques to solve them. Preferably, I'd be more interested in if/how one can use them in Machine Learning or Pattern Recognition. I know this is a very open-ended questions, so I will not get a concrete answer. At this point, I only require a board answer to help me get started to get acquainted more with this area. | 1 |
I translate some spiritual texts and this word revelation is very tricky to translate to another language that really does not have a similar word. For example: "God has sent a new revelation to the world." What could be good synonyms for it in a general (non-Christian) spiritual context, where I am coming from. The original text is in American English. Possible translations: New message New information Insight What else? Dictionaries mainly refer to Bible and book of Revelations, but that is just confusing, because this text is not about Bible and should not be confused with it. | 1 |
Possible Duplicate: Would you be weightless at the center of the Earth? The issue of weightlessness at the center of the Earth has obviously already been discussed, however I am curious as to know what will it feel like as a human. Will it be absolute weightlessness as experienced by being in space, or will the mass of the Earth surrounding you pull you apart in all directions in a free floating expansion with your eyeballs popping out, etc. | 1 |
When the context is science, the word "theory" means a logical/mathematical framework which tries to explain the phenomena. Infact in science "Theories" carry some "Claims" or "Predictions" while every sub-discipline of science could be presented in many number of theories. But in "Mathematics" the word "Theory" seems to merely refer to a sub-discipline of a mathematical field of study. For example I could call "Number theory" the discipline of "Studying Diophantine equations" or "Group theory" the "Study of certain types of algebraic structures(namely Groups)" or "Differential equation theory" the "The methods of solving differential equations". Does the word "Theory" in mathematics have some special meaning like bringing some claims or predictions or is it just a reference to the mathematical sub-discipline we are studying? | 1 |
Work is force applied over distance. Is it also reasonable to say that work is (the same thing as) the transfer of energy? When work is done, the equivalent energy is transferred. But if energy is transferred, such as by heating something, is that (or could that be) called work? Also, if a black body is subjected to a stream of energy, which it absorbs and radiates away, is any work done? The black body, let's assume, remains at a constant temperature, but energy is transferred to it and then radiated away. Is any work done? So what I'm really asking about is how the term "work" should be used. | 1 |
I was just wondering that is it ever possible that some object produces only invisible light when it catches fire? Something like invisible flames. If this is possible, can you please give one example? I have checked a phenomenon called Back-body Radiation and energy emitted by excited electron when fall back to lower orbit, which are responsible for colour of the flame. It looks like it is possible to produce invisible flames. Please correct me if I am wrong on any point. | 1 |
Stephen King (author of "The Shining") in his book "On Writing", writes: American grammar doesn`t have the sturdiness of British grammar (a British advertising man with a proper education can make magazine copy for ribbed condoms sound like the Magna goddam Carta), but it has its own scruffy charm I'm interested to know what King means by "sturdiness" here. Can anyone give some examples or more insight into what exactly King is talking about? | 1 |
I could only find this blog that suggests that complacence is "is a calm satisfaction with oneself" whereas "complacency means a self-satisfaction but coupled with a lack of awareness of what is happening around it." Is there a difference between the two and if not, is one more proper than the other? What would be the grammatical term for such a difference in the ending of a word? I just remembered that stagnation is probably the preferred word, so perhaps ignore the stagnancy vs stagnance part (stagnancy seems to be entirely incorrect anyway). | 1 |
I've heard a grammar rule which is, if there is any verb followed by a preposition except the 'to' preposition, the verb must have a 'ing'. As example, I've this sentence: I am going for playing. Where the 'play' verb is in 'ing' form. But in this sentence: I am going to play. the 'play' verb is in normal form. I just want to know that is the rule correct? If correct then is there any other exceptional preposition like 'to'? | 1 |
If I marry a woman and she has a child, I am a step parent. But what if the sequence is reversed? For example, suppose I am married to a woman, get divorced and she subsequently has a child by someone else. Is there any word in the English language to describe what my relationship (if any) is to this child? This is my situation; I'm close to this child and always at a loss to describe our situation as other than family friend. Can anyone offer another suggestion? | 1 |
I am new to LateX and I would like to know if there is a class which allows for creating a book cover design to send to the printers ? I already have the book cover design done in Adobe Photoshop with the front cover, spine. In other words, the final image is ready. How would Memoir Class work for this ? Now i only need to get it ready for printers, so I need to know how to set bleeds, spine, crop marks etc. to be able to send the final print ready pdf to printers. | 1 |
Today our teacher said that dual spaces are "big" and told us that this is a consequence by Hahn-Banach's theorem. So I was wondering whether the dual space of a space is always "bigger" or equal compared with the space itself? I thought a good way to check the adjective "big" by mathematical methods is to ask whether there is an injective map in the dual space. I am very interested in any comment on this. | 1 |
They say inflation must have occured because the universe is very homogeneous. Otherwise, how could one part of the universe reach the same temperature as another when the distance between the parts is more than light could have traveled in the given time? Why can't this problem be solved without inflation? If each part started with the same temperature to begin with, then they can have the same temperature irrespective of the distance between them. Am I missing something here? | 1 |
I have a set of numbers (each one corresponding to a payment made from the same person) and I would like to assign a probability value to a new specified number given that historical data. I've looked at the Chebyshev's inequality as a simple means to do that but I don't get the expected results. The formula evidences only obvious differences from the time series and also gives too little probability value to numbers that are lower than at least one of the historical ones. | 1 |
Assuming I rotate a disk, I want to know how long it takes to completely stop, and the number of revolutions it made since I removed my fingers off the disk. Lets say a DVD I rotate with my fingers. I only know the radians per second (velocity) of the last moment I touched the disc. Can you guys tell me where to start? Im trying to implement this on an iPhone app. So it would be nice if you mention equations. It should not be exact. | 1 |
What is the term for words that can be used as the opposite of themselves? I know there are a few of them out there, it is possible to 'Dust a cake with Icing' and if the cake were on a shelf for a long time (must be a bad bakery) then it would be acceptable to 'Dust the cake' to remove any dust particles... In this case, 'Dust with Icing' implies the addition of something to the cake where 'Dust the cake' implies the action of removing dust from the cake Other examples: Bolt - To hold in place or to Run away with haste... Trim - To remove a small portion or to add small bits that make it pretty... | 1 |
In an English-language text I wrote recently, I used this sentence It ain't pretty, but it'll keep! to describe the durability of a newly erected wall that (due to my poor masonry skills) looks hideous, but should withstand the floods it'll be shielding the property against. In my native German dialect, this is a valid use of "keep." But is it actually in English, too? | 1 |
I saw this expression: "the aim of the activity is "to show the fly the way out of the fly-bottle". " (It is connected with this other expression: "I don't know my way about".) I grasped the general sense of the expression but I don't understand clearly how it is formed, i.e. it's logical analysis (e.g, is "fly" a noun in this case?). Which are the logical analysis and the literal meaning of the expression "to show the fly the way out ot the fly-bottle"? | 1 |
So, from a cursory understanding of English history (and I am very happy to say that) I was able to, one might note that the cultural history of those who lived in England might proceed: Britons who spoke Brythonic Romans who spoke Latin Angles, Jutes, Saxons, et. al. (Anglo-saxons) who spoke various Teutonic dialects Normans (ironically, from the same stock as the former, but trained in French) My guess (and correct me if I'm wrong) is that the Latin influence in English was more to do with the Church and the Normans than it was to do with the Romans directly, but I was wondering if there are words which may be shown to be direct descendants of the ancient Britons' tounge? | 1 |
I am writing a short description of a social experiement. The objective is to get a better idea of the way people think. I have some troubles to understand the difference between those two phrases: To encounter people and better understand their way of thinking To encounter people and better understand the way they think Is there any difference in meaning between those two phrases? If so, could you please tell me what their are? Thanks a lot for your help! | 1 |
Say a roller coaster car is going up a ramp to a drop. At some point it needs to traverse a curve to get to the drop. In general, since the car is constrained to the rail, how is it able to move around on curves without breaking the car? Does there exist some kind of free motion for the wheels to move a little bit? Otherwise it seems like the car would bend. | 1 |
I understand that increasing current decreases the time taken for a capacitor to both charge and discharge, and also increasing the potential difference and charge increase the time taken for a capacitor to charge while decreasing the time taken for it to discharge. However, I am having troubles with deducing what effect resistance will have on it? Is it as simple as V = IR, and increasing resistance with a constant potential difference will decrease current (and thus increase the time taken for a capacitor to both charge and discharge?) | 1 |
Given a plane with an unbounded number of random points, is there an economical algorithm to find the Voronoi zone of any one selected point? I've considered making a "sweeping" circle from that point, adding a line to the zone boundary as I meet points of increasing distance; would this solution be correct as soon as I have enough lines to enclose a polygon? (The obvious corollary question is "If stopping as soon as the point is bounded isn't correct, when do I stop?") | 1 |
are you aware of a diagram showing all the connections between tex-related methods/engines. It would use terms such as tex - latex - context - luatex - xetex - xelatex - pdftex - pdflatex - etex and could even be extended to terms like xdvipdfmx and so on? All this is getting confusing, I think and it would be a good way to summarize. Thanks | 1 |
I have demonstrated that weight only is measured based on the gravitational pull of where you live. For example, the gravity on the surface of Mars is three times smaller than the gravity on the surface of Earth. So my question is simple: If we take into account that weight is only measured based on gravitational pull on that mass, if there was no gravity how would we define mass? That is, would mass weigh anything if no gravitational pull acted on it? Then what would be mass? | 1 |
I was recently shown a pretty cool video about common cosmological misconceptions. It got me reviewing the different between event horizon (current distance within which we will see/interact), particle horizon (current distance within which we have seen/interacted, and the Hubble Sphere (distance at which things are currently receding at the speed of light). I've found the following figure extremely helpful: But I'm very confused about the event horizon currently lying outside of the Hubble Sphere. If the universe is accelerating in its expansion, then it seems like everything outside of the Hubble Sphere at this moment - will never be in causal contact, never be within our light-cone, and thus be outside of our event horizon. Is this figure correct? | 1 |
If black holes must be in black holes in all reference frames, does the formation and or evaporation of SEVERAL black holes occur in the same order in all reference frames ie if one observer determines that black hole A formed, then black hole B, then black hole C, would any observers in any reference frame also be able to derive the same sequence for the formation of the black holes (or for the evaporation)? | 1 |
Possible Duplicate: How to prevent the paragraphs to spread out over the page? When I try to put some tables in my document I get lots of white space between the section (which I am guessing its because latex is trying to adjust positioning of the tables). Sometimes I get tables appearing on a single page by themselves. Is there a way to avoid this? Below is an image of a page showing the ugly spacing. (The boxes represent text areas) | 1 |
QKD protocol is a technique that allow two parties to share common secret key for cryptographic purpose and defined as being secure, by definition. But I am still wondering how can we measure that QKD is secure? In terms of what? and how can it be clearly proved? Is it possible by code it in any programming language like Java? well I am still looking for a good research topic under this area. | 1 |
Angular velocity is the rate of angular displacement about an axis. Its direction is determined by right hand rule. According to right hand rule, if you hold the axis with your right hand and rotate the fingers in the direction of motion of the rotating body then thumb will point the direction of the angular velocity. The direction of angular velocity is above or below the plane. But what does it mean? I mean in linear velocity the direction of velocity is in the direction of motion of body but what does it mean that body is moving in one direction while the direction of its angular velocity is in another direction? | 1 |
Give some Lagrangian we use the principle of stationary action to find the desired euqations of motion for something (e.g. a field). A lot of modern physics seems to be based on the principle of stationary action. I read it works for classical mechanics, general relativity, Quantum chromodynamics, quantum electrodynamics, weak interactions and more stuff. However, is there a field where the principle of stationary action does not yield the desired result or where it fails (contradicts some experimental result)? | 1 |
An object that takes physical, material, or corporeal form can be held and seen by humans. When we describe the opposite, something that cannot be held or seen by the naked eye, words like spiritual or non-material are used. I'm looking for a word that's more specific: something to describe the sequences of numbers packed into data chips and technology whatsits. "Information, whether of material or ________ form, can be found at the library." Assume that the library carries books and CDs/DVDs. In order to avoid wordy descriptions, does anyone have any suggestions for a single word that can fill the blank? I avoided antonyms of "physical" because they refer to things that are otherworldly. | 1 |
I'm trying to decide which sentence is correct, or if they both are. which would you recommend as easier to read/understand for the average reader? Hop the rocks quickly and get the star. Quickly hop the rocks and get the star. I'm using this in a promo for a game I made. Assuming both are valid, would it be better to use the first sentence since it begins with a shorter word? | 1 |
There is evidence that some galaxy clusters may experience some bulk rotation. If this is true, how valid is it to use the Ideal Gas Law to estimate the mass (actually, it calculates the acceleration needed to create the pressure gradient - from which the mass is derived)? One of the conditions for an idea gas is that collisions with the 'container' are elastic. If the galaxy cluster is rotating, then gas plasma particles will pick up velocity as they travel outwards (due to the centripetal force) and not bounce back as far inward. This is clearly an inelastic collision. | 1 |
I was reading this introduction to EPR and it seems to imply both that there is a unique g-factor of a given compound, but also that we can calculate multiple g-factors for a compound. For example, here's a picture on that page This clearly shows more than one g-factor for mitoNEET & Fdx. So is there only one g-factor or is it the g-factor at each specific value of the magnetic field that is unique? P.S. Is there a good book/ primer you could recommend to learn more about EPR spectroscopy? | 1 |
Since one can use singular they to avoid sexism in a way or another, I got stuck trying to figure if there is a polite word meaning something like "a group of both Ladies and Gentlemen" that could be put in the following phrase without implying in sexism: Do the Gentlemen need something? I thought about using Gentlemen, however, I have no clue if it implies in a group of men only. Can you help me out? | 1 |
I want to create a cloud of magnetic particles that will levitate in an electromagnetic field with an electromagnet. Is that possible? Is it easy to do or has it been done? I already have the magnetic nanoparticles and I just want to levitate them to form a 'cloud' so that each particle will stand in the air at specific distance from the others. They have the same size/weight. Would that be a problem? They need to sit in the air with specific distance between each other. Any ideas? Thanks! | 1 |
When I pronounce the phrase: "I'm proud of you" to communicate that I'm proud of the person I'm talking to, do I only need to stress the word "proud" a bit? I think that stressing the pronouns "I" and "you" are only needed when we want to make contrast between people, but it's probably less common. Am I right? The common stress pattern I think is something like: da-DA-da-da. | 1 |
I am trying to setup the Predictive Mode of Emacs and to use it with the LaTeX-mode. I have one problem: as soon as LaTeX-mode is loaded, it loads "auto-overlays" and it takes up to two minutes before I can begin to work, which is very annoying. I believe that this "auto-overlays" is used to switch between dictionaries according to where I am in the LaTeX document. Here is the part of my .emacs that concerns the predictive mode: (require 'predictive) (autoload 'predictive-mode "predictive" "predictive" t) (set-default 'predictive-auto-add-to-dict t) (setq predictive-main-dict 'dict-english predictive-auto-learn t predictive-add-to-dict-ask nil predictive-use-auto-learn-cache nil predictive-which-dict t) (add-hook 'latex-mode-hook 'predictive-mode) (setq completion-use-hotkeys nil) (setq predictive-ignore-initial-caps t) (custom-set-variables '(auto-completion-syntax-alist (quote (accept . word)))) Do you have a solution? | 1 |
So, I was at the bar last week, Behind the bar they have these signs with jokes on them. One of them said "If your drinking to forget, please pay me first"(This isn't the question, I get this joke). Somebody at the bar, noticing it, said to the bartender: "I don't have a drinking to forget, but if I did, what about it?". The bartender, looked confused, and then the guy pointed to the sign. The bartender still didn't get it, and he laughed at her. But I didn't get the joke either. This sentence doesn't make any sense to me. Why is it funny? | 1 |
I'm relatively new to TeX, which means I did nothing more than homework and some math things with it. Now I'd like to write invoices with LaTeX (for reusability etc.) I am not searching for a template. What I'm looking for is actually more a starting point and maybe some resources that already helped other people to get started with writing invoices or similar kinds of documents. Where should I start in order to learn to write more complex documents with LaTeX? What helped you? | 1 |
If A,B,C are normal subgroups of a group G where B is a subset of A. Then show that A intersection BC equals B(A intersection C). I m a newbie in abstract algebra n i m new to rigourous mathematical proof. I know that to show two sets are equal i must show that each one is a subset of the other. Plz solve this question | 1 |
In diagrams I often see light waves depicted as little sine waves that travel through space. And often when describing polarizers, the explainer will angle their hand to show the angle of polarization and bob it up and down in a sine wave action, apparently emulating the amplitude of the wave. My questions is, is the amplitude of light really like this? Where it moves up and down or side to side in space? Or, is the sine wave relationship just an analogy? | 1 |
All the time I see people replying with "of course I will" or "yes it is!" (to "it's not that good" and not placing a comma after "of course" and "yes". The second case seems even more extreme, as even placing a comma would not help - it would still be a comma splice. However, if I do place the commas, the sentences become very confusing, as many people would probably read that as "I will, of course" and "it is, yes". Now, to me it seems that grammatically, there is no option but to leave the commas in place - though, again, this may cause confusion. Any ideas? | 1 |
Higher algebra by hall and knight states that"A compound ratio can be formed by multiplying together the fractions which denote them or by multiplying the antecedents to form new antecedent and multiplying the consequents to form new consequent" but what is the meaning of the word compound ratio.If ratio is used for comparison then what is the purpose of compound ratio? Can anyone help me?. I will be grateful. | 1 |
Which of the last three verb patterns apply to the verb 'recommend'? I recommend that you wait. (present subjunctive, American usage) I recommend that you should wait. (substitute for present subjunctive, British usage) I recommend waiting. (subject of the gerund not mentioned) I recommend you/your waiting (subject of the gerund mentioned) I recommend to wait. (subject of the infinitive not mentioned) I recommend you to wait. (subject of the infinitive mentioned) | 1 |
Is a good example of 'intestinal fortitude' when someone faces his/her fair share of adversity and bounces back from it? Or when a boxer is repeatedly pummeled and knocked down in a fight, and he keeps returning to his feet to continue notwithstanding the beating endured (he's showing a lot of heart, internal strength and 'guts')? Can you say 'He had the intestinal fortitude ('guts') to call me a buffoon'? Is 'ovariological fortitude' the female equivalent of this term? | 1 |
In Lagrangian Mechanics we choose the path of least action. Given a uniform gravitational field, and a particle of finite mass; and fixing two points the start & end-point we consider all paths connecting the two points and minimise the action. This turns out to be a Brachistone, as first shown by Bernouilli. When we fix the end-point vertically below; the Brachistone is in fact astraight-line. But is there a principle in Lagrangian Mechanics that allows me to choose the point vertically below? Of course, we know from Newtons Mechanics that this must be the case. But how do we determine that end-point entirely within Lagrangian Mechanics? | 1 |
In the context of usable security (related to computer science), a major challenge is to provide security means in such a way that all of the people including those with some disabilities (e.g., blindness and deafness) be able to use information systems. So, in some cases we need to refer to these two general group of users. The question is how to do so in a respectful way. For example, referring them as ordinary and disabled users is a bit harsh. Also, I don't like using "disabled users and users without any type of disabilities" to refer them. What's the best way to describe these two group of users? Shorter options are preferred! | 1 |
Classically, if one has an electron orbiting a proton, how can the magnetic field felt by an observer with the same instantaneous velocity as the electron be calculated? It seems that I may find the magnetic field felt by this observer by boosting the proton to the same frame as the electron at some instant, and then calculating the B-field generated by transforming the E-field of the proton in the rest frame. Is this not the correct reasoning? If not, why so? | 1 |
Can I make a heat pump beat the Carnot efficiency? Why is the Carnot process the most efficient one? If I have a heatpump that is sphere shaped, and cascaded in layers like a onion can I beat Carnot efficiency? Heat would be transferred and concentrated from the outermost layer that is in contact with ambient air, and brought towards the center to heat a fluid. | 1 |
Please, help me to clarify this question. Assuming that there are many books I owe to a person and some of them are here on my table, is it correct to say: "The books I owe you are on my table"? Will it show that those books just belong to ones I owe to the person, and somewhere else are other books I owe him? Or will it strictly mean that these are the only books I owe? The confusion is because "the" is often used for an exhaustive list. And if to say: "The book I owe you is on my table" - the same question - can it just show that this is one of those books and there are other books I owe somewhere? Thanks. | 1 |
I am wondering if saying "tune to this music" would make sense? Guitars can be tuned to particular note, can people tune to song, or music, or idea? Google doesn't return many results for "tune to" so I guess it sounds strange, but I found a song "Tune to the Music" by Status Quo. I am asking this question because I am looking for a name for new web site related to music and songs and tune-to also came to my mind. | 1 |
I was doing so research on neutron stars and I bumped into this stock exchange page. Does a neutron star burn? Quote from an awnser: The Pauli exclusion principle causes the neutrons to resist further compression. That is, the neutrons, being identical fermions, can't all be put in the same state. So to get them closer and closer together you have to go into higher and higher energy states. This confused me, how can a neutron be in an energy state. Does this relate to nuclear strong force in any way? | 1 |
Person A uses the phrase "eager beaver" to mean an enthusiastic person. Person B chuckles. Basically my question boils down to who the weirdo is, so to speak: A, because "eager beaver" is outdated and the sexual connotations are too strong to hope that one should understand the "normal" meaning B, because "eager beaver" is a perfectly benign phrase with no sexual meanings whatsoever. Anyone who sees sexual connotations in this phrase is simply being immature. | 1 |
