"Half of the time I was working from about eight in the morning until eight at night, and the other half I was incapacitated by excruciating pain." This is what I have currently. Is this correct or is there a better way to approach this sentence? To be specific, I am wondering about my comma usage, and whether or not m... | 1 |
I learned a lot from prof Tao's notes and books because unlike many authors, he seems to prefer writing more words, explanations and intuitions rather than just mathematical formulae. His approach is also very pedagogical, and quite often, when talking about one concept, he also talks about similar concept in other fie... | 1 |
I'm new in this study and I don't know much about the foundations of mathematics, so I have a question. If I'm doing category theory, and I need to talk about "small categories" , "locally small" and etc, I need to have some set theory foundation like NBG where I can talk about this things, right? But, if I want to tak... | 1 |
I'm looking for a foundational book that builds up ideas like transcendental functions. For example, how the trigonometric functions are truly defined when plotted as continuous functions. I believe Shilov briefly touches on this in his "Elementary Real and Complex Analysis", but I'd like a more broad and in-depth trea... | 1 |
We all know that it uses less energy to go by wheeled transport than walking if the terrain is smooth and there are not too many hills. We also all know that when going up steep hills we get off whatever wheeled transport we are using and walk. To make things concrete, let us consider a child's scooter. How can one cal... | 1 |
The phrasal verb "sit on sth" means "to be a member of a group of people". Well, according to Longman, "to sit in / on sth" means "to be a member of a committee, parliament, or other official group", the same thing. I don't know why my phrasal verbs book "says" just "sit on sth" and doesn't say the "in" too. Perhaps Pa... | 1 |
I was wondering how one would actually calculate how much oxygen would dissolve into water given the necessary initial conditions, and what those initial conditions would need to be. I assume they would be pressure, and initial concentration, but I really don't know where I would go from there. Clearly air and water ha... | 1 |
I'm designing a space ship for a comic I'm writing. I was just finishing up the first sketch when I thought whether such a design would actually be possible. Hence my question: A spaceship is located in deep space. A propulsion system (let's make it a rocket) is attached to the side, and thus not in one line with the s... | 1 |
Let S be the intersection of diagonals in a cyclic quadrilateral. Let p be a circumcircle of a triangle ABS and it intersects BC in M and q is a circumcircle of a triangle ADS and q intersects CD in N. Prove that M, N and S are collinear. I tried proving that vectors NC and DC are the same, and also that vectors CM and... | 1 |
Question: Why is ionic lattice energy inversely proportional to the radius of the atom? Most heterogeneous covalent molecules are polar to some extent. The degree of polarity, or the dipole moment, depends on the difference in electronegativity difference between the two atoms. The larger the dipole moment, the higher ... | 1 |
As far as I know, a magnetic field can only be produced by a moving electric charge, or from a particle's spin (this is how a permanent magnet works, all the spins are in the same direction) What is strength and direction of the magnetic field of a stationary electron at the origin with spin oriented straight up? I sus... | 1 |
I would like to know the status of the following problem: Given a simple graph, is there a walk traversing each vertex at least once and each edge at most once? (I am asking for a complete trail, a sort of cross-breed between Eulerian and Hamitonian walks, in a way.) In particular, is that problem known to be solvable ... | 1 |
Sometimes I'll look at a word for too long and I become convinced that it's spelled or pronounced incorrectly. This happens most frequently with "spider" (I think that should be pronounced "spih-dur" [like "spitter"], not "speye-dur") and happened just now with "finger" ("fin-gur", not "feen-gur"). There's a similar va... | 1 |
I'm currently studying Single-Variable Calculus independantly through MIT OCW. I can only focus on one course at a time independantly since it takes up so much time, and I really want to study Linear Algebra next instead of Multi-Variable Calculus. My question is simply this: after understanding Single-Variable Calculu... | 1 |
I've just been wondering about how atoms and molecules can be quantum mechanically thought about, and I have a question. It is often said that intermolecular bonding is purely "electrostatic". I hope what this means is that it is easier to consider molecules as point charges that are attracted, but in reality, there is... | 1 |
Are binary systems (in case of stars and other celestial bodies) more favorable than independent existence? I've been going through an article regarding pulsars, where it was stated that 'many pulsars are found in binary systems.The companion of pulsars have been found to be normal stars, planets, white dwarf stars, ne... | 1 |
Source: gradestack.com This is a problem I am trying to solve for a long time. But still not able to proceed. After spending some time, I got a doubt whether this question is correct. Because, in a rhombus, diagonals bisects each other. Here PA=PC. That means, P is the center point of diagonal AC. So PD must be equal t... | 1 |
I am interested in why many small animals such as ants can lift many times their own weight, yet we don't see any large animals capable of such a feat. It has been suggested to me that this is due to physics, but I am not even sure what to search for. Could someone explain why indeed it is easy for smaller objects/life... | 1 |
A set of r marbles is selected from an infinite supply of red, blue, white and yellow marbles. A selection must satisfy the condition that either the number of red marbles is even and the number of blue marbles is odd, or the number of white marbles is even and the number of yellow marbles is odd. Does it mean a select... | 1 |
I am looking about similar triangles and I always see the word corresponding but I always forget to include it in the definition. I am trying to think of an example I can use to show the importance of the word corresponding. So here is the definition: Ex: "If the measures of the corresponding sides of two triangles are... | 1 |
Most of the proofs of the Cauchy-Schwarz inequality on a pre-Hilbert space use a fact that if a quadratic polynomial with real coefficients takes positive values everywhere on the real line, then its discriminant is negative(e.g. Conway: A course in functional analysis). I think this is somewhat tricky. Moreover I ofte... | 1 |
Autorefractors are being used by eye opticians for eye diagnosis. I searched internet for articles and wiki page as well but I wasn't satisfied. I am interested to know how do they actually work. How the machine is able to focus sharp on retina automatically. How do they figure out spherical/cylindrical aberration for ... | 1 |
I received an e-mail including the following sentence: I am not asking for a facetious grade change, just one that would allow me to pass. What the writer means is that the request isn't frivolous or petty. This use sounds wrong to me, but the literal dictionary definition doesn't contradict it (the dictionary definiti... | 1 |
The product of nonempty sets is nonempty. I am fascinated that such a simple and seemingly intuitive statement can lead to rather astonishing results such as the Banach-Tarski paradox or the solution to this riddle. I am also intrigued by the seemingly innocent results that rely on AC (the existence of algebraic closur... | 1 |
Let G be a finite planar graph, then there is a natural walk around the outer (i.e. the unbounded) face of G. It might happen that a vertex v is visited more than once by this walk. Proof that this is a cut-vertex. This is a task which might be obvious at first glance, but I wasn't able to do it rigorously, i.e. by cit... | 1 |
I am looking for a good mathematical rigorous introduction to solid state physics. The style and level for this solid state physics book should be comparable to Abraham Marsdens Foundations of mechanics or Arnols mechanics book for classical mechanics or to Thirrings Physics course for quantum mechanics. Any recommenda... | 1 |
Is there any way to tell how many clusters there are with respect to all the roots of a polynomial? Specifically, I'm after the multiplicity of each root but since I would like to work in floating-point arithmetic I'm afraid I have to deal with clusters. I don't mind any method of finding out: be it by numerical-iterat... | 1 |
Example: The three picked up their chopsticks and started on the food. The scene seemed strangely normal to Naomi. It was as if everything were OK, and her mom were perfectly healthy. In fact, she looked more lively and energetic than Naomi remembered. The whole illness issue seemed like a distant, bad dream. Something... | 1 |
As I've been trying to wrap my head around the principles of decoherence and quantum behavior I am left wondering why fundamental particles are 'allowed' to exhibit quantum properties even in ideal conditions ( close to absolute zero and in a 'box'). If a particle/photon behaves in a probabilistic superposition state a... | 1 |

Wikipedia defines the notion of a pure set as follows: a hereditary set (or pure set) is a set whose elements are all hereditary sets. Why does this definition make sense? It seems to be circular. Also, wikipedia says: The inductive definition of hereditary sets presupposes that set membership is well-founded (i.e., th... | 1 |
The original sentence is "The Spaniards brought horses to the Americas." I recently have made a final-term test question like this: Q: Where did the Spaniards brought horses? A: ______________________________________(Make sure to use the 'it-cleft') Not a few students answered like this: "It was the Americas that the S... | 1 |
We have terms like 'high culture' and 'high art'. They are used to describe things deemed of a higher quality, or held in higher esteem, than products of popular culture. We also have terms like 'art music' and 'art film'. What I'm looking for is a similar term to describe literature. Like high literature or art book o... | 1 |
I'm looking for a way to truncate outliers in a time-series graph. Some context: I'm plotting two different metrics on a single graph. It's important to understand what portion of "Metric A" takes up respective to "Metric B". "Metric B" can at times spike to a high value thus increasing the Y-Axis scale which then mini... | 1 |
Context: I'm programming a system for exams, each exam has people on it, in the industry we would call one of these people a 'Delegate'. Unfortunately in the programming language c# 'Delegate' is a reserved word and I can't really use it without my code looking terrible. I need a word to represent a person who will be ... | 1 |
How does quantum electrodynamics actually explain HOW reflection occurs on a microscopic scale? Note that Feynman's QED lecture series/book is not sufficient, as he only assumes that light DOES reflect ('turn around and go back') in order to expound his path integral theory. My question is why does light have the prope... | 1 |
I'm not very advanced in LaTeX. I don't know what e.g. XeLaTeX or LaTeX->dvipdfmx are. I only use ShareLaTeX and used to use Overleaf.

According to Wikipedia, the past tense (and past participle) of the verb to output is either output or outputted. Are these two forms entirely interchangeable? Or do they have certain nuance in meaning or context (e.g. in programming one of the forms is preferred)? Instead of correct results, my program output/outputte... | 1 |
So one of the exercises I am doing is to prove (or disprove) that 'Every compact set on a metric space is bounded'. Verbally, I can 'prove' this by simply stating: "If the every compact set on a metric space is not bounded, then there exists an infinite number of open covers, and if something is compact, there are only... | 1 |
I've heard people using this idiom, such as "each day is better than the next", or "you hope that each experience you have is better than the next" (heard this one on a TV show not long ago), apparently in a positive way. However, if taken literally, I find the meaning very negative - if the current thing is better tha... | 1 |
Linkin Park sings "wash the poison from off my skin" in Castle of Glass. Shawn Mendes sings "ripping all the skin from off my bones" in Mercy. As far as I can remember these are the only two occasions where I have heard that expression. To me it sounds like it should be "off from" (if at all). Is this normal, or did th... | 1 |
I have been on and off of this problem for three days and need to present the proof tomorrow. I am thinking that because I know for any element in the additive group of integers modulo n the order for that element is the ratio of n and the greatest common factor of that element and n then I can say,[...chirp, chirp, ch... | 1 |
"My female cousin working for a finance company was dismissed. Disappeared along with her job were her confidence and smiling face." There is a very complicated system in Chinese for naming different relatives. For example, in Chinese, different words are used for a female cousin and a male cousin. Also, the word for a... | 1 |
I am trying to implement Microsoft Excel's GROWTH function in JavaScript. This function calculates predicted exponential growth by using existing data. What makes it tricky is that it must work with multiple sets of known_x's values. I could not find any reference equation. Any suggestions? The part that might be relev... | 1 |
I'm interested in writing a numerical integrator to solve the motion of systems of pendulums. For example, a simple case would be the double pendulum. The motion can be quite complex in general. Is there a way to determine if a system of pendulums is going to produce stiff DEs before actually trying to integrate them? ... | 1 |
I am fairly new to this so apologies for informal terminology. After I discovered what space filling curves are, I came to the conclusion that any point in any number of dimensions can be represented as a single number along a space filling curve, given that the curve covers enough space. I also imagine that it is poss... | 1 |
I've found plenty of blog posts and papers where the authors claim that the Higgs mass divergence (usually presented with a momentum cutoff) doesn't show up under dimensional regularization. Unfortunately I've never seen a book or paper which explains this with any more detail: it's usually just stated as a fact. Is th... | 1 |
I need some assistance with a calculation I'm trying to do. I have access to surgery waiting times data (date arrived, date completed) and I want to figure out the expected waiting time for a new patient - this should take into account the number of patients already waiting and those who have completed (I think). I've ... | 1 |
People on Reddit often comment "I lost it" while quoting the funniest part of a joke to highlight how funny that part is. As I don't speak English much, I am not sure if this is Reddit-specific, but I guess not. Where does this come from? Is it related that laughing from a joke is similar to "losing your mind"? That se... | 1 |
I've searched the question in the forum, and found the following conclusion : - "In electromagnetism, electric flux is the rate of flow of the electric field through a given area. Electric flux is proportional to the number of electric field lines going through a virtual surface. But, It doesn't make intuitive sense to... | 1 |
I've heard mentioned in various classes that neutron stars, like superconductors, are described by BCS theory. I know that in superconductors a key element in forming cooper pairs is a net attractive force between the electrons which would normally repel one another. That attractive force is accounted for via lattice v... | 1 |
I have to submit some paperwork for the approval of an activity. However, I have already got approval, the paperwork is only necessary to submit the specifics (the date, people involved, and other details which have already been approved) for sign-off. What is the word (or expression, but preferably a single-word) to d... | 1 |
I've been studying the representation theory of groups from Tung's "Group Theory in Physics." I understand Young symmetrizers of different Young diagrams are essentially primitive idempotents in the group algebra of the symmetric group and then all inequivalent minimal left ideals as well as all inequivalent irreducibl... | 1 |
What is the meaning of the text quoted below? In the physical world, if a system is described by an equation that is first order in time, the system is general dissipative (has energy loss). If the equation is second order in time, the system may be non dissipative. Such a system has time-reversal symmetry. Can somebod... | 1 |
I'm thinking of those old U.S. wartime movie-theater newsreels that celebrated victories, but combined with aspersions and taunts on the enemy. "We're great and those guys are idiots." Not necessarily in film format like a newsreel; maybe a printed publication. Example: The Mouth of Sauron Magazine, the ??? of Mordor, ... | 1 |
Several people I know were good in mathematics when they were in high school and they loved it but when they joined a university (specializing in mathematics) they felt mathematics is hard and that they were somewhat deceived because this wasn't the type of mathematics they loved and joined the university to learn. How... | 1 |
After reading this answer about the gravitational force I wondered how that applied to the electric force, since both have the same basic form - product of the masses or charges over distance squared. If I was in a charged metal-walled elevator that was "falling" in an electric field, would I be just as oblivious as my... | 1 |
I asked a question on one of the stackexchange sites and one user edited a sentence I made from "We were relocating so we...." to "We were moving house so we....". As an english speaker, I have never heard of "moving house" in context of relocation in a sentence before. Presently I am even doubting if relocating is cor... | 1 |
In many mathematics texts I've seen "ordered n-tuple" appear, and in such texts, there isn't any mention of just "n-tuple". So I'm wondering: are there really cases where one writes "n-tuple" and somehow it's not ordered? If not, I'm thinking the "ordered" in "ordered n-tuple" is really not necessary and can be shorten... | 1 |
I had to edit my question because I think it led to misunderstanding. For me, the definition of "immunity" is quite different from "impunity", and I know the differences. But what I don't know is that is the law the thing that draw the line? It seems to me they both refer to exemption from punishment. for example, a po... | 1 |
Which is the better verb to use with data: feeding or entering? Furthermore, which is more common in the literature of the field and which do people who work in the field say more often? Are they used for different kinds of input systems? If the data are automatically continuously input by a machine (e.g., the Mars pro... | 1 |
I want to use beamer (Madrid style) for a presentation I'm giving next week, but I am forced to use the institutional title page. That means that the whole background is filled by an image and the title itself cannot be in a coloured box. In the worst case I will have to pdftk the title page onto the presentation, but ... | 1 |
My teacher made an example to explain DFA, it was about paths (URL paths), the rules were as follows: S ::= / S ::= /O O ::= [a-z] O ::= [a-z]R O ::= [a-z]S R ::= [a-z] R ::= [a-z]R R ::= [a-z]S Examples of paths could be: /foo, /foo/, foo/bar and so on. However, I don't understand why you would need the R rules since ... | 1 |
The problem is, that I fail to unambiguously understand this phrase. There are two ways in which I can understand it (and a number of similar phrases): I may never be able to do this = It's impossible for me to ever do this ('never' negates 'may') I may never be able to do this = It's possible that I will never be able... | 1 |
According to Newton's laws, if net force is zero on a particle then the particle is at rest or in uniform motion, and if it is not zero then it is accelerating. So when a car moves on the road, friction helps it to accelerate. If the acceleration is zero, (i.e) it is moving with constant velocity, the net external forc... | 1 |
I have to do a final project for my PDE subject and last year I did one about Game Theory (specifically, Prisonner's Dilemma and Snowdrift game) for my ODE subject, which the rest of the students enjoyed and which my teacher thought it was a fun approach to the contents of the subject. I want to do a similar thing, but... | 1 |
The title gives away pretty much the entire question except for the fact that the class of functions I am interested in is a subset of twice continuously differentiable functions. I think that if an odd function (defined on the whole real line) is concave on the positive real line, then it is convex on the negative rea... | 1 |
Do you know if the concept of chemical potential can be properly defined for nucleons in the nuclei? I mean, if I can picture the nuclei like an interacting gas of nucleons, then may I think of a chemical potential for nucleons, similarly to the case of an electron liquid. Of course the nature of the interactions is di... | 1 |
So imagine you're at the beach; you go into the water and the moment you enter the water you stop hearing anything from the outside world.

Would appreciate a quick response... | 1 |
The usual solution to fix lines that overflow is to rewrite it. However, that hardly works with bibliography entries that experience the same problem. So what can I do to fix it? I can't rewrite anything since the information needs to be "as-is". I can't provide a minimal example because if I take the entry that overfl... | 1 |
I have studied in a course several algorithms to integrate ODE's numerical: Runge-Kutta, Predictor-Corrector methods, Taylor...

Why is it true that the lower sums of f with respect to some partition is less than the lower integral (which is the supremum of the lower sums) I think what I'm confused about is the difference between a lower sum and the lower integral, how can the lower integral be the supremum of the lower sums when a lower sum is ... | 1 |
Gravitational force is mediated by graviton exchange. If I am standing outside a black hole, I can of course feel the attracting force towards the black hole.

I'm looking to communicate the idea that performing a task would be less costly (more than just financially; technically, or when risk is considered) if you start from scratch or anew, instead of attempting to alter or change some existing object or entity. The closest phrase I can think of that satisfies this is "it m... | 1 |
Is it always true that projective objects are retracts of free objects? I know that retracts of projective objects are always projective, so in particular, retracts of free objects are projective.
