Are there any (mathematical) puzzles that are still unresolved? I only mean questions that are accessible to and understandable by the complete layman and which have not been solved, despite serious efforts, by mathematicians (or laymen for that matter)? My question does not ask for puzzles that have been shown to have... | 1 |
If a couple are having a romantic or sexy get away where they're staying in bed and having sex and otherwise hanging out - is there a term use for the periods where they're not actually in the act of having sex? Perhaps pillow talk is the closest term I can think of here - but this seems to refer to the act of just tal... | 1 |
I'm not a native english speaker (so forgive me for my poor language skills in general :) ) and I'm puzzled by this "whose / which / of which" issue. I have a sentence like this: "BLAA is a project whose purpose is to build and...". To me it sounds that it should have which instead of whose. I was always tought that wh... | 1 |
I intend to study linear algebra during my summer vacation.I will be thankful if anyone could please point me to a good text.I do not care about the difficulty as long as the book is self contained.I do have some experience with problem solving and proof-writing. Edit:I don't care about applications.I prefer one which ... | 1 |
I was wondering if there was any way to flip a transistor or similar node component around in the circuitikz package? For the bipoles it's fairly simple as you just reverse the start and end, but for more advanced circuits I'm having trouble (things such as current mirrors or what have you). I've seen various solutions... | 1 |
I was aked to solve the following problem: Guiven three lenghts and a triangle ABC, from every vertex whe draw one of the three lenghts, find the conditions such that the three lenghts meet in one point. Then I suposed that at least two lenghts and a side makes a triangle, supose that the side is AB and the two lenghts... | 1 |
I've seen constraint and restriction used quite often in scientific literature. For example, This algorithm needs to be further improved due to severe space constraint and restriction. I simply can't figure out the subtle difference between constraint and restriction. They seem to be circularly defined according to eac... | 1 |
I am looking for a high school/ pre-college level Algebra book that is self contained for self-study. Nothing special, I don't want a book about number theory, but a book in preparation of high school geometry, trigonometry and calculus. I have noticed that recommendations for Algebra books on this site, start with boo... | 1 |
In my report, I am defining/describing some terms. What is a proper way to start and format a sentences like: The term crawling denotes the practice of ...

This might seems off topic or something, but I am a middle school student and i'm really into Quantum Field Theory and String theory and every video on youtube or article on the internet shows only the concept and Intro to these theories but I want to know about the maths envolved and do the maths myself as well , so i... | 1 |
So the category of affine schemes is dual to the category of commutative rings, Stone spaces are dual to Boolean algebras, localizable measurable spaces are dual to commutative Von Neumann algebras, and I'm sure there are many more examples. In general, a category of algebraic structures is going to be dual to some rel... | 1 |
I've been trying to find one single word that covers knowledge concerning both the properties and cultivation of plants, but have come short with some words. Here are some of the words I thought of, but eventually found lacking: Botany: I feel this implies purely scientific research on plants, ignoring the cultivation ... | 1 |
I'm trying to come up with a better word to describe a "driver" or "conditional"; basically, the name of an object or event which is a trigger for something else. Would it be appropriate to say that a button which turns on a light is an affector? If I believe I understand its usage in this context, it would only be an ... | 1 |
I just need to know what exactly happens when charging/discharging a capacitor. Is there any heat transfer between the capacitor and the surroundings? Is there a heat transfer between other parts of the surroundings (wires, the battery)? Another thing I don't understand generally... How do we know if a process is rever... | 1 |
Me and my dad are having a dispute over if this is is a run on sentence or not: From making silly pictures on Photoshop to playing a game that brought me to another world, and even being dubbed as the IT guy in elementary school. He argues that it's a run on, and the ending can't stand on it's own. I think otherwise. M... | 1 |
I was wondering if there is a method for finding primitive idempotents of a finite dimensional algebra (over a field)? or in other words is there any way to build the complete set of primitive idempotents from one (idempotent)? Or if it is impassible to find a method, I believe a good reference or some tricks (general ... | 1 |
Sometimes, I forget to use the proper form when an adverb is required. Or sometimes it simply doesn't appear to me one is required, unless I actually consider the grammar of my sentence. I suppose that's mostly because in my native language (German), there is no morphological difference between an adverb and an adjecti... | 1 |
I'm doing an analysis, of client contracts that contain the following factors: The per-unit license price (A) The initial order quantity (B) The recommended retail price (C) What I'd like is a single figure that represents "How good of a deal" the client got, with the quality of the deal being a low license price in co... | 1 |
This is perhaps a beginner/simple question, but how does includegraphics determine the "box" encapsulating a vector graphic embedded on, say, a letter-size paper? When I read my EPS files (generated with Matlab) using GhostView, they appear in some corner of a full-size, otherwise blank page. Do the various page proper... | 1 |
What is the principle behind centrifugation? I understand the idea that you spin something around the centripetal force will cause an apparent force on the spinning system. However I don't quite grasp how particles (in the non subatomic sense) with different density should be affected differently. Quite coarsely, I wou... | 1 |
For a long time I have been investigating this question on my own, but it seems impenetrable. The question is this: To find a method whereby it becomes possible to convert proof A into proof B, where the proofs A,B can be of anything, e.g. a lemma, theorem, etc. For example, it is possibly in geometry to solve somethin... | 1 |
I have some confusion over the ER=EPR conjecture. In what way does entanglement in the laboratory lead to black holes? I must not be reading the literature correctly. Perhaps it should read " It's possible to entangle particles near an Einstein-Rosen Bridge in a way to effectively show ER=EPR by appropriate measurement... | 1 |
Here is an example from Murphy's grammar textbook: You are in a restaurant. You and your friend are looking at the menu. Maybe your friend has decided what to have. You ask her/him. You: What ...?

So everybody says the gravitational field has no curl, and is not comparable to a liquid swirling around a drain. Observationally, of course, there are many examples of vector fields (which I think are gravitational fields) which look like they have some curl. A pair of stars, for example, one being slowly devoured by ... | 1 |
I am looking for a book (or article, or notes...) explaining details about the link between integral points on varieties defined as complement of certain divisors and integral solutions to the equation(s) defining the divisor itself.

It's common to say that a pregnant woman is expecting, but is it acceptable to say that her husband is expecting? I ask because my male teacher's wife is expecting in a week. In case you didn't know, to be expecting means (for a pregnant woman, at least) that one will be giving birth soon, but it could generalize to ma... | 1 |
I was reading about function and I came across this text, If A and B have same number of elements and particularly if A = B then we only need to prove one of either onto or everywhere defined to prove that it is a bijection. Now I don't get this point. I will be thankful if someone can elaborate this with an example. T... | 1 |
I have found out that using the verb be in passive constructions such as: I had my house be burned down is incorrect, therefore it should be I had my house burned down. But is it possible instead of be to use get? E.g. The wire is passed through the pliers in a specific way to avoid having it get bent. The rope had its... | 1 |
Serre's Duality Theorem is well known and well studied and, as far as I know, there is a "big" algebraic proof for the general case, which is now kind of standard, and can be found in Hartshorne and other references done pretty much in the same way. On the other hand, there is an analytical proof for the small case of ... | 1 |
In layman's terms, how do you determine the resistivity constant of a non-ohmic material having measured voltage and current? I understand that non-ohmic materials don't follow Ohm's Law, but will this still be able to be used to determine the resistance? Otherwise how can I determine an initial resistivity in order to... | 1 |
Suppose there's a box with one face cold, and the opposite face hot. So when the air molecules hit the cooler face, it will transfer its momentum and energy to the wall, bouncing back with less momentum. And when molecules hit the hotter face, it will bounce back faster. And the hotter side will be hit more frequently ... | 1 |
If I place two positive charges of different magnitudes on the x-axis (one at the origin, one at the some position x), as the two charges repel each other are the forces that they impart on each other the same? Why? Edit: I'm working on a problem that has that situation, and the problem asks for me to find the position... | 1 |
I have to do an experiment about light. I preferred to measure the speed of light by the experiment of Michelson and Morley. When you do the experiment, it will result in an interference pattern by changing the distance of one of the mirrors. I know they had the intention to measure the speed of light relative to the e... | 1 |
If I call my mother when I am done shopping in the morning, I might tell her "I am coming home" if she is at home, but "I am going home" if she is not. That afternoon at home, discussing the day's events with my father, I could say "I had already planned to come home after shopping," or "I had already planned to go hom... | 1 |
A pattern that begins a word is generally denoted as "prefix", one that ends a word is generally denoted as "suffix". Is there a word that indicates a pattern that surrounds a word. For instance (hello), is there a word that indicates the parentheses? So if I have several patterns i.e.: "hello" (hello) {hello} [hello] ... | 1 |
I am not a native speaker of English and I am now reading a Sci-Fi book called Dune. I am unable to grasp all the sentences but I do get the overall meaning of paragraphs.

I've just lost a word I use frequently whenever talking about the reasons for punishments. The word should (I think) fill the blank: Punishments, such as jail time, __ people from doing crime. The word is related to stopping, hindrance, incentive, restrict, etc. In this usage, it should also imply that it stops people ... | 1 |
I'm using TextMaker. This is my first time using bibtex. I tried a simple example found in forums where I created a .bib file and ofcourse a .tex file.

In many religious calendars, the day goes from sunset to sunset. When translating to the civil calendar, you can divide that day into two parts: from sunset to midnight (A), and from midnight to the following sunset (B). For terminology, "eve" works well for part A. Is there a term for part B? The closest I've found ar... | 1 |
Do you think that the following sentence structure is correct? "Attach any material you need included". I meant to say "Attach any material that you need to include". I agree it may not be formal but I don't think it is wrong or difficult to understand. Do you think that the sentence is wrong? If yes, where do you thin... | 1 |
I'm trying to understand the symmetry content of the conductivity matrix: one information is, presence of time-reversal symmetry causes the off-diagonal terms to vanish. When this is broken (e.g. in Hall effect) off-diagonal terms become finite. (A side question is, why is the conductivity matrix always anti-symmetric?... | 1 |
I have heard that in America, and likely elsewhere as well, we are beginning to be more gratuitous with our use of extreme words when not entirely accurate, such as the words "awesome", "always", "never", "crazy", etc. Is there a word or phrase to name this phenomenon? What are the implications of this behavior with re... | 1 |
In the photocurrent experiment, if the intensity of light is kept constant, but the frequency is slightly increased, what's the effect on the saturation current? I think saturation current should decrease because the number of photons should decrease. But, all my reference books say that the saturation current depends ... | 1 |
I couldn't help but wonder every time I saw such a noun phrase. I've seen both forms used equally often, so I guess both of them can be used interchangeably. But do I guess right?

Every word I say is true; this I promise you. I think the pronoun 'this' is the direct object of the verb 'promise' and 'this' should be be placed after 'you', but it is placed at the beginning of the sentence. Because this sentence is on a web page about English grammar at http://grammar.yourdictionary.com , I believe... | 1 |
Is it theoretically possible for an object or particle to change to the opposite direction without making a complete stop first? Lets say I have a fictional hammer swing setup like this: I fire an electron to the hammer and the hammer smashes it back, is it possible for the electron (or any other particle or body) to c... | 1 |
I have recently been reading about Quantum Electrodynamics which I found very interesting, but even more confusing. I understand photons mediate the electromagnetic force and interactions between charges can be described by virtual photon exchange.

I vaguely remember seeing something like a "picture" of various groups a while back. It was as if the elements of the group were each associated with a point and many points had segments connecting them, but not all were connected. Does anyone know what I am talking about? If so, would you care to take the time to expl... | 1 |
Is it possible for a black hole to be ejected from a galaxy after an encounter with the central supermassive black hole? What would be the impact of the passage of the hyperV-BH through the galaxy? Is it observable? Have we observed any hypervelocity black holes? What experimental techniques do we need to be sure (how ... | 1 |
I'm thinking of writing a paper on a new way of deriving the conservation of energy from symmetry principles and the Galilean transformations, but I'm not sure where to publish. Taking a look at AJP, it tends to be there for teachers at universities writing papers on how best to teach a certain topic, and to clear up m... | 1 |
Hmmm... You can definitely drop down the voltage, and ideal capacitors don't dissipate any power. So it seems, at first glance, that you could use a capacitor divider as a lossless voltage step-down device for AC. So you could use a cheaper variable cap divider as a replacement for a Variac? And it would be continuousl... | 1 |

I've been wondering if there is a word to express that something was current at the time of its creation. It (in bold) should plug-in into a sentence similar to: The results are based on an analyses that deal with the then-current methods. As far as I can tell, both "contemporary" and "current" refer to now, whereas I ... | 1 |
I am looking for a textbook in control theory (for a friend) that covers topics such as Pontryagin's maximum principle. My friend is not a mathematician by trade, but holds a degree in applied mathematics (and is thus not math-shy, but prefers to skip detailed discussions on regularity and prefers intuition). Recent as... | 1 |

In the phrase "My dog wiggles it's butt" there seems to be a division of opinion as to whether the use of the apostrophe is grammatically correct.

To negate a participle phrase we use not at the beginning of it, as in "Not having heard the news, he had no idea what was going on."

So basically, you have three different types of 'things' (for lack of a better term): You have that which is necessary, that which is contingent (you have a choice), and that which is necessary but only because it must be so after a contingent choice has been made.

I was trying to measure the noise of a device with metal probes. I was not sure whether I should trust the results because I was told contact noise might contribute to some degree. I am a little confused about the notion of "contact noise". Is it because of the contact resistance (every resistor is a noise source)? Or ... | 1 |
Usually, I think "have to" indicates obligation, which is pretty similar to "must".

In German, there's a term "Reizblase" which describes the bladder of someone who has to hit the bathroom every ten minutes.

The thing is, the German word holds up nicely in ... | 1 |

When I look in old mathematical textbooks from the seventies and before, mathematics is always upright. Their use of italic letters in other contexts, however, shows that this is not because of technical limits. On the other hand, all textbooks I have seen with italic math look very TeX-like. So I was wondering if this... | 1 |
In compton scattering, a photon may deliver only some of its energy to an electron. But when dealing with photon electron interaction in an atom, it's all or nothing. Why the difference?
