However, the bibliography contains the DOI, the URL, the ISSN, a further e-print... | 1 |
I came across this problem in my textbook, and I don't understand why the answer is 'as' and not 'that'. "We are attracted to people who have a sense of humor, who can laugh at the same things ____ we laugh at." In the sentence above, the word that goes in the blank is 'as' according to the textbook. Could someone expl... | 1 |
I want to apply the Biot-Savart law to calculate the magnetic field at a point created by current flowing through a square/rectangular conductor. More specifically, a trace on a printed circuit board. To me, a trace on a circuit board is the summation of many infinitesimal rectangular conductors. I have seen lots of ex... | 1 |
I just came across the following sentence in the book "The theory of everything": If one keeps traveling in a certain direction on the surface of the Earth, one never comes up against an impassable barrier or falls over the edge, but eventually comes back to where one started.

When someone has unreasonable expectations and feels that he is owed by others, this trait is described as a "sense of entitlement". But how do you refer to the person who has this trait other than calling him "a person with a sense of entitlement"? If there is no single word to describe this kind of character, can you... | 1 |
Let's say I want to describe a habit in the past (something that happened many times over and over again) in the form of a conditional statement. Is the following sentence grammatically correct?

I have been trying to understand the notion of parallel transport and covariant derivative. I am unable to see why the change in a vector when it is parallel transported from one point to another shouldn't be a vector. If it is, why isn't the Levi-Cevita connection not a tensor ? Hence my questions are : What is a conn... | 1 |
I need some help with the following question: In the game of "odd man out" each player tosses a fair coin. If all the coins turn up the same except for one, the player tossing the different coin is declared the odd man out and is eliminated from the contest. Suppose that three people are playing. What is the probabilit... | 1 |
I've just switched from mac to windows and have just started using TeXworks. I like it, but I find that the default pdf viewer is difficult to use.

While reading my copy of "Resnick and Halliday", I noticed that the book has made a distinction b/w the terms " degree celsius" and "celsius degree". When I googled this, I was able to find only one matching hit(on the first page), which stated that while degree celsius is the unit for the measured temperature, celsius... | 1 |
A single toss of a fair coin cannot be predicted. But if we observe a large number of tosses, we can prove mathematically the law that roughly half of them will show up heads. The movements of individual molecules in a gas cannot be predicted and can be assumed to be random. But if we observe some macroscopic phenomena... | 1 |
Here's what I know about dark matter: Astrophysicists realized the movements of galaxies and other astronomical bodies cannot be explained by the gravitational effects of matter known to be there, so either there is a lot of matter missing that doesn't react with light or general relativity needs to be fixed. For the p... | 1 |
So, I have been solving a number of exercises involving contraction mapping. However, I am struggling to understand what exactly contraction mapping is at its most basic.

I was wondering how this phrase sounds in English: She is a little bit shy. In my country the people say "a little bit" a lot, and sometimes they use it wrong. I have the impression that in US (or even in other countries where English is spoken), people prefer to be more specific saying "She is shy". Anyway, I don't wa... | 1 |

Additional questions I have are: Is there a difference between van der Waals and Casimir forces? Are there... | 1 |
This question on a different SE site asks the question of what the etymology of the word "Xenomorph" is, and the consensus, from the comments at least, is that it has none - that it was purely invented for that movie. My question is, is this true? Did this word purely exist as a creation of the movies, as a portmanteau... | 1 |
I looked up the definition of a Joke on Dictionary.com which gave me this "Something said or done to provoke laughter or cause amusement, as a witticism, a short and amusing anecdote, or a prankish act."

A recent paper authored by Niayesh Afshordi and Joao Magueijo is in the news claiming to challenge Einstein's theory on constancy of light speed. It says light might have travelled with a faster pace during the initial stages of Big bang which apparently sets aside the inflation hypothesis. My question is whether it ac... | 1 |
I'm writing a thesis in a scientific area, and in a draft I wrote that it was "not possible to tell which set of data is more accurate", meaning that it was not possible to tell which was closer to the true values of the thing being measured. One of my supervisors objected to this language, claiming that either one is ... | 1 |
I have been reading up on the correct use of 'which' and 'that' but I am still struggling. I am unsure if 'must be taken regularly' is restrictive or not. Both 'which' and 'that' sound correct to me.

What is the trajectory of a particle in a string or a rope that goes under the effect of a wave pulse. The illustration in this image is not what I am asking about, I just attached it in order to give you an idea of the case I mean. If you give me a picture of the trajectory, I'd be grateful. Thanks in advance. | 1 |
I find typing `a word' and ``a word'' quite inconvenient, because I find it rather annoying to type ` and `` all the time. Instead, I'd prefer typing 'a word' and "a word" (which I often do when I don't pay attention, causing wrong displays). I was hoping the inputenc package would make this possible, but apparently it... | 1 |
It is well-known that in a Noetherian UFD, every height one prime ideal is principal. I was wondering whether this statement holds if one replaces 'UFD' with 'locally factorial domain'. I am aware of the fact that 'locally factorial' in general does not imply 'factorial', i.e., 'unique factorization' (though have never... | 1 |
Can anyone tell the difference between these two phrasal verbs above? A soldier took the flag down from the flagpole. A soldier got the flag down from the flagpole. My father took the electric fan from the wall. My father got the electric fan from the wall. To me, these four sentences look exactly similar in meaning. I... | 1 |
I've been told that HJB equations can be solved numerically. I know very little about the subject, could someone provide a couple of comments or a reference (ideally, one that is accessible for a layman) on: What are the main numerical methods used and, roughly, how do they work? What are the limitations of the methods... | 1 |
I'm doing some research for a book I'm writing, and, as the title implies, I'm looking to understand what happens when a supersonic jet sustains in-flight damage. Specifically, what happens to the occupants if the cockpit is breached? (I assume that this is why jet pilots wear masks?) Could a jet maintain super sonic s... | 1 |
First of all, how exactly do you entangle two atoms? I've heard about how they entangled atoms in quantum Teleportation experiments, but I don't get how they did it. I've heard that the atoms must "interact", but what exactly does that mean? Do they have to touch? Do they have to be within a certain distance - like a f... | 1 |
After spending some time researching about the centrifugal force, I now understand that it is needed in a non-inertial reference frame for Newton's Laws to hold true. However, I don't understand why we only feel the centrifugal force when moving in a circular path. For example, if you imagine yourself being spun around... | 1 |
I am studying elementary particle physics and I am wondering what a parton level Feynman diagram is? My understanding is that partons are representations of the quark and gluon substructure of hadrons, and so I am assuming that any diagram that has a quark or gluon qualifies as a parton-level diagram, but I cannot find... | 1 |
There are many 'rules' on the net saying that a comma should be placed before the relative pronoun 'which' in a non-restrictive clause. (http://www.oxforddictionaries.com/words/relative-clauses) But would the sentence have the same meaning without the comma before the relative pronoun? Does omitting a comma before a re... | 1 |
I am wondering whether there are countably many or uncountably many spanning trees of the integer lattice rooted at a particular vertex, say the origin. In a spanning tree rooted at the origin there is a unique path from each vertex to the origin. There are countably many paths to the origin for each vertex, and each s... | 1 |
I'm taking an intro to proof via number theory class and I'm trying to prove that if a|b and b|c then a|c. So you write down there exist integers k and m such that ka = b and mb = c. Then you substitute ka in for b in the second equation and write (mk)a = c (by associative property). We know (mk) is an integer by the C... | 1 |
The reason I ask this is because I was trying to draw multiple lines in pgfplots (I was trying to make a drawing showing how Riemann sums and integrals are connected). And after unsuccessfully trying to use a for loop for an hour or so, I found this solution, which was pretty unsatisfying since it's just a workaround f... | 1 |
The difference between rational and irrational numbers is always stated as: rational numbers can be written as the ratio of two integers, and irrational numbers can't. However, why do mathematicians make a distinction between these two types of numbers? Why are integers special anyway, other than being historically sig... | 1 |

It seems to me that "optical" relates more to the mechanics of light and vision, whereas "visual" is a much broader term. For example, hallucinations are classed as "visual" or "auditory", rather than "optical" or "acoustic".

In Australian English there has always been a distinction between "pissed" (intoxicated) and "pissed off" (angry, irritated).
