According to the Bernoulli's equation, if velocity decreases, then pressure increases. I am trying to understand the Bernoulli's effect based on a situation. Suppose we have a stream of water. Let's assume it is an ideal fluid. Imagine the water flows out from a wider pipe to a narrower pipe. Since the area decreases, ... | 1 |
I hope this isn't an inappropriate question here! I'd like to ask the following (perhaps slightly ill-posed) question: why do we study prime ideals in general (commutative or non-commutative) rings? The situation is somewhat clear to me in some nice cases such as Dedekind rings, but even in slightly more general settin... | 1 |
The following quote from Anthony Burgess has a comma after it: There is, in fact, not much point in writing a novel unless you can show the possibility of moral transformation, or an increase in wisdom, operating in your chief character or characters. But this quote from William S. Burroughs doesn't: There is in fact s... | 1 |
While learning about shock waves in an introductory Gas Dynamics course, it was revealed that normal shocks are unstable if formed in a converging channel. Even if the local conditions ostensibly require the presence of a shock in the converging section, the flow instead chooses to reinvent itself, moving the shock wav... | 1 |
We are struggling to find the correct word(s) that describes a list of all messages in the system that are sorted by recency. Trending does not work because what we are displaying is not what is popular in the system, only the most recent. Recent does not work because it implies there is a limit to the number of messag... | 1 |
In an electron gun, the heating filament heats the cathode, releasing electrons by thermionic emission. I've read that "electrons are negatively charged particles and the positively charged cylindrical anode develops a strong electric field that exerts a force on the electrons, accelerating them along the tube". Howeve... | 1 |
My understanding is that in quantum mechanics the wavefunction may be expressed as a function or as a ket vector (composed of many orthogonal ket vectors). I'm not too sure about the further differences between these two approaches. For example, I am familiar with operating on the wavefunction as a function with the ha... | 1 |
What is the English word for "collecting money for a special event from a group of people"? For example, say some friends are planing a party. Each one has to contribute some amount of money to the event. What is the word or phrase that can be used to explain this kind of activity? I have found "fund raising" to have a... | 1 |
I'm trying to write a tagline for my live blogging service, and this is what I've come up with: Live blogs that are a breeze to write, a pleasure to read and are actually updated in real-time. Is that correct grammar or should it be Live blogs that are a breeze to write, a pleasure to read and actually updated in real-... | 1 |
Given any problem, how do I know whether it is solvable using Dynamic Programming? For example: consider the rod cutting problem. Now, how do I know whether dynamic programming will give me an optimal answer? Basically my question is: how do I check if a problem follows the "Principle of Optimality" - that optimal solu... | 1 |
In mathematics we often have statements like a x <= b, where a and b are constants and x is a variable. Now there may be variables satisfying the inequality (that is the statement is true) as well as variables violating it (in which case it's false). However I don't have any words in my vocabulary to express stricter s... | 1 |
Let's say me and a colleague are going to a meeting and I want to make sure his responses to the questions raised are similar to mine, that we are in agreement and we will responde in a similar manner. Can I say: "Let's make sure our responses are aligned" or, "Please let me know your views cause I want my responses to... | 1 |
The words "opportunism" and "opportunist" suggest the ability to take advantage of situations -- but they assume that one is doing so for one's own benefit, which makes the terms pejorative. What is a non-pejorative word in English that means "have the skill and wisdom to recognize and seize opportunities that lead to ... | 1 |
This image from NASA illustrates drag coefficients for several shapes: It is generally accepted that some variation of the teardrop/airfoil shape has the lowest drag coefficient. I was wondering what shape has the highest drag coefficient. The image suggests that it is a flat plate, and that would seem to be an intuiti... | 1 |
Clouds are made out of tiny droplets of water. These droplets, to my understanding, act like tiny prisms (which is why there are rainbows after rain). From my line of thinking, if we had a room with a bunch of prisms randomly placed about and had a light enter from one side, the walls would be quite colorful. Why, then... | 1 |

This is possibly a silly question but when we derive the equations of motion of a particle using the principle of least action. We must assume that there is a single minimum (for a fixed choice of boundary conditions), right? What happens if we have two minimums? How do we decide what trajectory that particle took? Is ... | 1 |
I am documenting a piece of software that will be transferred to a customer. The customer will run the software continuously. They may choose to update and improve it, but this is optional. To keep the software running smoothly, there is a minimum set of upkeep tasks that must be done periodically. Things like checking... | 1 |
I am working on a barn door tracker for taking astro photos. My drive train has a small periodic error that I'm trying to eliminate and I was hoping someone might be able to suggest a formula that would approximate what is shown in the attached image. The image shows three cycles of the error. It appears to me to be si... | 1 |
I am currently completing a maths project that aims to approximate the roots of functions using MATLAB. The two root finding methods that I have used are inverse quadratic interpolation and the secant method. I have written scripts for both methods and have obtained approximations to the roots of different functions. I... | 1 |
Wikipedia gives the following definition of a formal proof: A formal proof or derivation is a finite sequence of sentences (called well-formed formulas in the case of a formal language) each of which is an axiom, as assumption, or follows from the preceding sentences in the sequence by a rule of inference. Given this d... | 1 |
I have heard of impulsive differential equations being used in some epidemiological models of infectious disease. I haven't heard of them before in my math education, and I was wondering how they might work. I presume there is some mechanism to introduce a step-wise/impulse discontinuity, but I'm not sure what a simple... | 1 |
In the foreword for a knitting book there's this passage: Knitting has become as ubiquitous as the humble sheep. Which is followed by a couple more sentences on how great it would be to learn how to knit etc. I've googled "the humble sheep", and haven't had any success. Is the phrase roughly equivalent to "Wool is ever... | 1 |
I'm using the word subscription with the following meaning: subscription: an arrangement to receive something, typically a publication, regularly by paying in advance.

Our company occasionally has to write letters to a third-party in response to a complaint. There are times when we only know the complainant's last name (usually with first initial). Typically, we would write something like "Mr. Jones signed up for service on..." or "Mrs. Smith contacted us on...". If we do not know th... | 1 |
A Ponzi scheme is a fraudster uses money from new investors to pay old investors, so that it looks like he is doing something profitable. At some point, when all the investors want their money, he doesn't have it (because he took some of it). A key part of the definition of Ponzi scheme is fraud (the fraudster said he ... | 1 |
I am using Tikz externalize for the figures in a manuscript. The original files containing the Tikz/pgfplots code have been deleted (but will be regenerated in several hours when my simulations finish running). In the meantime, I would like to make a few changes to the text and give it to someone else to review. I stil... | 1 |
I'm wondering if there's a word or term for a person who looks for an opportunity to insult and berate other people. I'm sure you've all been there; you're using an online public forum, like Facebook, to voice an opinion. There's always that one person who gets completely offended, or they take things completely out of... | 1 |
First of all, I ain't a native speaker. And one of the most confusing sentences to me is I ain't going to this place no more. Ain't in this sentence basically means am not, so it translates to I am not going to this place no more. What exactly does no more in this sentence mean? Does it have the same meaning as any mor... | 1 |
I am facing an example that I am not able to understand at all. It says the the limit of a pointwise convergent sequence of positive semi-definite metrices is positive semi-definite. Basically, I do not understand how to use the pointwise convergence for a matrix, that is, I do not know a definition that is general eno... | 1 |
Here is the full question: Prove that every continuous function on a closed interval is Riemann integrable. Give an example of a continuous function on an open interval which is not integrable. I think he might be Riemann integrable for the second question because I'm pretty sure that every continuous function on an op... | 1 |
I am brand new to lattices/partitions. Given that the set of all partitions of a finite set is a poset ordered by refinement, how does one prove that it is a lattice? I know you have to prove that the join and meet exist, but how does one construct them in this case? In other words, what are the join and meet of two pa... | 1 |
I have been reading about Jupiter as of late and reason I am asking is if Jupiter has strong enough gravity to pull hydrogen to itself then it should be only matter of time when it will acquire enough mass to ignite itself and become a star, same would apply to any other planet that is big enough to hold hydrogen (In o... | 1 |
As I understand it (and admittedly it's a weak grasp), a computer processes information irreversibly (AND gates, for example), and therefore has some minimum entropy increase associated with its computations. The true entropy increase is much greater, and comes from the conversion of electrical energy to heat. How effi... | 1 |
In my mathematical writing in grad school there used to be sentences like "Whenever x is a fish, then x is an animal." (Yes, that's what my dissertation was on!) I am a native speaker of English and this seemed fine to me. My adviser (who is not a native speaker of English, though it's not entirely relevant) insisted t... | 1 |
I notice that a lot of researchers tend to have crappy-looking websites, often because they aren't willing to put in the time it takes to learn HTML, CSS, and design principles--they'd rather do research. I'm assuming that said researchers know LaTeX, as it's pretty much the standard for academic typesetting. So why no... | 1 |
I once asked some English people the following question: "At what time do you go to sleep?" They gave me a blank stare. You see, I tried to avoid the standard expression "At what time do you go to bed?" because it is ambiguous. I may get into my bed but may not fall asleep right away. I may be reading or emailing on my... | 1 |
I'm looking for a mathematical treatment of mass action kinetics under the assumption of detailed balance. In particular, I'm interested in the proof that the free energy is a global Lyapunov function. There are many papers that prove this for the more general case of "complex balance". However, I'm not particularly in... | 1 |
This has been bugging me for a while, does anyone know what this word is? Maybe I imagined it. I thought it might have been "superfluous", but I don't think that is it, then I thought it might have been "hyperbole" but I do not think that is it either. Any thoughts? Here is some context. Person A: If a billion people v... | 1 |
Is there a term for the word that describes where a person is from or what nationality they are? For example, someone from America is an American, and someone from Finland is a Finn. Is there are term for the words American and Finn that denotes that they mean "someone from a particular place"? I could have sworn I stu... | 1 |
To me "I must help her" sounds wrong. I feel that I would rarely say this. On one website they say that 'must' is more for personal obligations (e.g. I must help my mother.) and that 'have to' is for external obligations (e.g. my boss says I have to finish the report.) Is it that simple (and vague)? Or does anyone have... | 1 |
Is the sentence: "We felt we had let our coach down because we hadn't won the match" correct? I read a sentence "We felt we had let our coach down because we didn't win the match" in an English textbook. I wonder that, when we compare the happening time of the three things: A "feel" B "let our coach down" and C "did no... | 1 |
I'm interested in knowing the structure of a CNOT gate, in quantum computing. THe problem with that is, that I've read how the structure of a nuclear quantum computer works, but I still don't understand how that can be implemented to create a quantum CNOT gate. I've read the article of the original proposal of Cirac-Zo... | 1 |
A: I can't understand why my parents keep me from buying fast food. B: Me, too. It's delicious. Does B's answer sound natural? In Korea, we usually teach that we should use 'me, neither' in a negative sentence, 'me, too' in a positive sentence. But I am not sure if this is always true. I think that 'me, too' is a valid... | 1 |
While reading about linear algebra for math olympiads in these notes, I came across the following assertion: Remark. The set of invertible matrices form a Zariski (dense) open subset, and hence to verify a polynomial identity, it suffices to verify it on this dense subset. Could someone provide an explanation of what i... | 1 |
I'm in the process of learning about Matroid Theory (I'm reading Oxley's book). I came to this from combinatorics and topology. Now, I just read of connections between matroids and combinatorial optimization. Yet the only example I've seen so far is that of the greedy algorithm. So, I'm wondering if there is some astou... | 1 |
The Free Dictionary defines it as "to start to accept and deal with a difficult situation," but I don't know what accept means in this expression. Does accept mean to welcome the difficult situation? That can't be right, as I've heard "come to terms with" pertain to one whose friend or family member died, and I doubt a... | 1 |
I was excited to learn that XeLaTeX finally has microtype support (I had asked about that earlier). However, after adding microtype to my document, I noticed that line breaks at hyphens now go wrong. Previously, the word foo-bar would be hyphenated as: foo- bar But with microtype enabled, I now get foo-bar and that run... | 1 |
I'm working through Mumford's Red Book, and after introducing the definition of a sheaf, he says "Sheaves are almost standard nowadays, and we will not develop their properties in detail." So I guess I need another source to read about sheafs from. Does anybody know of any expository papers that cover them? I'd prefer ... | 1 |
As a physics newbie I'm trying to get a grip on basic orbital mechanics. I think I'm beginning to get grasp on how bodies interact with each other. When a body approaches another body it accelerates due to gravity. It can reach a point where its velocity is high enough to keep falling but also keep missing the object i... | 1 |
I have a circle with a known center and radius. I have an arc with a known radius and two points on its edge, where one end is at the same position as the circle's center. Is there a way to find their point of intersection that's simpler than turning this into two circles and intersecting those (and somehow figuring ou... | 1 |
I'm having trouble deciding whether the word 'name' can be used possessively. Currently I'm thinking it's correct to say: Patients' names have been altered to provide anonymity However it just doesn't look right to me. Is the above correct for a group of patients or would any of the following be better: Patients names ... | 1 |
What is the rigorous justification of Wick rotation in QFT? I'm aware that it is very useful when calculating loop integrals and one can very easily justify it there. However, I haven't seen a convincing proof that it can be done at the level of path integral. How do we know for sure that Minkowski action and Euclidean... | 1 |
I have been studying the concept of transcedental numbers. Till now, I had taken it for granted that all important numbers like pi and e were transcedental. I have no reason for assuming this or for clustering them together. It's just my intuition had placed numbers like pi, e and the golden ratio together and for some... | 1 |
I have a problem analysing this sentence from the point of finite/nonfinite clauses, clause elements and their functions: He does not want to destroy his parents' dream of him achieving a Cambridge degree.

In a one dimensional lattice system with periodic boundary conditions, in which the last and the first site of the lattice are the same site, momentum is conserved modulo a vector of the reciprocal lattice. My question is if for a system with open boundary conditions, in which the single particle wave functions vanish ... | 1 |
When you put chopsticks (or any other object) in a glass cup of water, why do the chopsticks seem curved or bent? Is it because of the shape of the cup, the water, or the chopsticks itself? Note: I'm sorry I currently don't have an image of it. You can try this at home. Just put a pair of chopsticks in a glass of water... | 1 |
I am a first year student at varsity and I am new to Astronomy. A question came up in my tut asking about the Hubble constant and cosmological time.

Consider the quote from "What is a Grantor Trust" article. This trust is revocable, which simply means it can be altered, modified, and otherwise changed or even terminated during the life of the grantor, provided that the grantor has full mental capacity.

I'm a programmer and like to name my variables as accurately as possible (who knows who will be reading my code in a few years' time?) I've been thinking about sports video games recently, and have thought about the idea of a generic sports game engine. Most sports games have an arena, crowds, a playing surface and pla... | 1 |
I think to answer this question we would have to fully understand the nature of black holes. It seems to me that the smaller black hole could have a lower density than the larger one. In this case the smaller black hole might be effected by the tidal forces of the larger black hole. But if the densities of the two blac... | 1 |
Is it somehow possible to extend TexStudio to use dictionary words in autocompletion? For example, when I type "som", I want the autocompletion list to show me all words from the dictionary starting with "som". I know TexStudio uses autocompletion for words that already appear in the same document. I've tried to create... | 1 |
I'm trying to create my own ultrasonic humidifier. I ordered the misting part which works great but it only functions correctly in shallow water.

My assignment asks us to prove or provide a counter example for If R is symmetric, then Rc is symmetric. I know that if R is symmetric, then (x,y) and (y,x) are both in R, but what I do not understand is what is R^c, what does R^c do to the relation? I believe that complement basically means "not", so does that mean th... | 1 |
The metaphor of a surface (typically a pool table or a trampoline) distorted by a massive object is commonly used as a metaphor for illustrating gravitationally induced space-time curvature. But as has been pointed out here and elsewhere, this explanation seems (to a layman like me, at least), to be "hopelessly circula... | 1 |
A field F is algebraically closed if every non constant polynomial in F[x] has a root in F. Is this the right definition? I am wondering if only one root in F and the rest of the roots not in F can also be considered 'algebraically closed'? I remember reading somewhere that if a root is in F then all roots are in F. Is... | 1 |
Assuming an object is moving in a straight line propelled by a force. How much energy would that force have to exert so that there are no known forces or objects that could stop it from moving in that straight line? I'd guess limits like the speed of light might come into play here, but it would be interesting to know ... | 1 |
I am in sales and when I make a cold call I typically begin the conversation with, "I just wanted to..." Some common phrases are, "I just wanted to see if you might be interested..." or "I just wanted to follow up with you..." I hate this phrase as it shows a lack of confidence and it's not truthful. I want more than J... | 1 |
I am a newbie to Mac OS X. I installed TeXmaker and found that the Chinese characters in the interface are garbled completely (see figure below). I tried a lot to fix this but nothing worked.

Apart from Cantor's diagonalization argument, there are a number of ways to show that cardinality of R is greater than that of N (eg: Baire Category theorem, path connectedness of R and so on). Are there any arguments outside Set Theory which naturally lead us to sets of higher cardinality than R ? In other words, if S... | 1 |
In prime numbers, one has the sieve of Eratosthenes, which is a method of computing the next prime, once you have all previous primes: You just cross out the multiples of the previous primes on the number line, and the first remaining number is the next prime. I wonder whether there is such a method for prime gaps. Of ... | 1 |
I have a problem in Texmaker. I have divided a document into a number of subfiles. I would like to compile the whole document from the current subfile without running the master file.

I was looking at reviews for Sakurai's Quantum Mechanics textbook, and some mentioned it being outdated, specifically mentioning his use of imaginary time. Is this idea deliberately avoided in modern treatments? I can't see why a simple parameter change t->it, would be or not be an outdated concept. It doesn't make thi... | 1 |
I am looking for a word or phrase regarding something that is "impossible". I can't seem to put my finger on it, but I am trying to think of the word to describe something that is the top of the top, and thus impossible to achieve? The only two words I have come up with are elusive and formidable, neither of which real... | 1 |
According to Biber's Longman Student Grammar of Spoken and Written English, insterts are one of the three families of words (apart from lexical and functional words).

I believe the answer to this question is yes. I was hoping someone would critique my logic. Let X be a separable and metrizable space. Then it has a countable dense subset A. Let B be a basis for X. For every a in A, choose a basis element U in B such that a is in U (if such exists). This forms a countable collection V... | 1 |

With reference to Black holes in particular, how can you approximate the luminosity of an accretion disk? It is possible to quantify the temperature at a given point, but as the disk is not a black body, and this temperature is at a specific point, I am unsure how to equate this to luminosity - surely you could not do ... | 1 |
I happened upon the following sentence in a textbook: 'An increase in the number and size of islets is characteristic of infants born to diabetic mothers.

I recently found myself in a situation where I wanted to use a line that went something like this: "...we must examine the effects these ideas had on their respective creators..." and I just couldn't find the right word in place of "creators". Something feels off about "creators". We don't create thoughts we have thoug... | 1 |
In the book The Road to Reality by Roger Penrose, projective geometry as developed during the Renaissance is framed as (eventually) playing a pivotal role in quantum mechanics.
