I am not very good at speaking and listening English. Can someone please suggest some songs, which have clear pronunciation of English words, to listen and understand the songs too and also I can use them to improve my vocabulary. Actually very fast music, especially those with too many and loud musical instruments never helped me understanding the lyrics.
What is the physics behind welding iron? It is obviously the electricity that causes the two metal parts to fuse but what is the role of the welding rod and why is it said to damage your eyes when you look at the spark. Is it just the brightness, or does it radiate a specific wavelength that is more damaging, such as UV rays?
The universe is believed to have originated from absolutely nothing, and we know it is still expanding. Physics says "something can arise from nothing". I understand how mass and energy are related and one can take the form of other. But, how can everything arise from absolutely nothing?
I am pretty new to Turing Machines and I am trying to understand the basic things first...so my question is , would this machine accept all words ending in 'a' ? if that's the case would the REJECT state be all string without 'a' and ending with 'b' ?
Is this sentence correct? She will grow up hating what she sees in the mirror. Or should it be: She will grow up hating what she will see in the mirror. I think first one is correct, I just want to know why and the rule.
"packet" and "package" are synonyms when we refer to mailings, but does the same apply to "network packet"? My co-worker frequently says: "network package". It's like nails on a chalkboard to me, but is it correct?
Which one is more proper to use: 'allocable' or 'allocatable'? Sources say the former is derived from the original Latin word 'allocare', while the latter is a part-of-speech-variant of the English word 'allocate'. Also, is there a standard rule in English to form able-ending adjective of words terminating in 'ate'? Thank you.
I need to find uses and interesting questions by using jacobian matrix for a project work ,can any one help me. I found jacobian matrix is used in dynamical systems, but i didn't understand it.Is there is any question in dynamical systems which is connected to jacobian matrix
I have the same problem like here: How to create custom section titles with a "<title> <number>" format in ConTeXt? But I would like to solve it in LaTeX. Is there a simple way to adapt code from the @phg's answer?
If I tell you the real and imaginary parts of the index of refraction for all frequencies, name a property that can't be predicted based on that information. If you're assuming this is a gas, specify your answers to properties measured in gases. Likewise for solid, etc. edit: I see my question is not a good fit for this site: https://physics.stackexchange.com/help/dont-ask My apologies!
I am making a small book and I want to put a phrase in both pages like the picture above, I want to keep the chapter title and page numbers. Could you give me a hand on this?
Well, our professor in class posed a question to all of us: Is frequency a scalar quantity? The obvious answer, of course, is yes, it is, because it does not have a direction associated with it. But then, a scalar is defined as a coordinate invariant quantity. In the case of frequency this obviously fails (the Doppler shift). So how do we classify it?
Is there a general name for the following properties, (similar to the properties of existence of an additive identity, existence of multiplicative identity etc): For any given set, the intersection with the empty set results in the empty set. For any real number, multiplication with zero results in zero.
I have a question that is short and sweet: Are spectra (both fluorescence and absorbance) of any molecule dependent on temperature? In particular, is the spectral lineshape function of any molecule dependent on the temperature (so, kinetic energy) of the surroundings and possibly itself?
Why is this a wrong Triangulation ? I have to say, we had triangulation at the end of the topology course, so not in details. And the professor only mentioned the basic rules for the triangulation, but in this case, idon't know why it fails.
I was reading the book "Theories of Integration" by Douglas Kurtz, and I have a question about the following proof from the book. Specifically, would it be valid to replace the argument that follows "It remains to show that A satisfies the Definition [of Riemann Integral]" by: Thanks!
If it's infinite, is it countable or uncountable infinite? I am a newbie to this topic... I don't know what modular arithmetic for polynomials means. Can someone please give me a link where I can learn?
I have problem with sentences structures. I have sentences: I specialize in design wireless and wired network infrastructure, configure devices company's Cisco Systems and MikroTik, and security and techniques used successfully to protect IT resources. Additionally, I have knowledge of voice over IP (VoIP) technology. I am not sure, is this sentence grammatically correct? Thank you in advance for your help.
If one rotates a function such as the sine function about the origin, is there a general method to find the taylor series for the rotated function? Assuming of course that the rotated function is still a single valued function.
I would like to find a mathematical function like the one I sketched below. My first idea was to rotate a sin function, but now I don't think that would work because I would like the function to be well-defined so that for one x, there is only one y.
I understand that the quadratic equation can solve any second order polynomial. Furthermore, equations exist for polynomials up to fourth order. However, without a graduate level degree and a deep understanding of mathematics, is there an explanation of how we can prove that the equations for solutions to a fifth order and above don't exist? Thanks in advance.
Suppose you met a famous person, and you were shy and anxious and almost overwhelmed by them. Is there a word for describing that? Similar to getting stage fright, or "choking", except in this case for a person? When he said hello to me, I couldn't respond. I (was) __________.
When two nouns come together like taxi driver, the role of the first noun is noun adjunct. Now the question is what is the second noun's role. I mean the role of driver in taxi driver. Thanks
I feel like it could mean either "what you are capable of doing," or "what you are willing to do." Do one of those better represent the meaning of this phrase or are they both right?
I've been trying to look at stopping times and continuous time change in martingales but have trouble understanding without some concrete examples. Anyone knows of any good references that might be helpful? Thanks!
A wire has cylindrical symmetry, therefore we should consider the possibility of the induced by field in the p,phi and z directions. I know from the right hand rule that we only get a field in the phi direction but I'm not sure how we show that there is no field radially or along the length of the wire.
I wrote the following sentences: Eyed closed, he imagined the moment disintegrating, returning to the stars, and continue existing there for eternity. Eyed closed, he imagined the moment disintegrating, and returning to the stars to continue existing there for eternity. Now, I'm not sure if I should say continue existing there or continuing existing there.
Suppose I somehow know propagator for a given quantum mechanical system but I don't happen to know either the Lagrangian or Hamiltonian. (For simplicity, assume that this is non-relativistic.) Is there a procedure by which I can recover the original Lagrangian?
I used to say cleats but found it uncommon for some people, though I had no trouble with soccer shoes. I have always lived in a Spanish-speaking country (Nicaragua) so I find it hard to know why that is. Are cleats only used in some places? Wikipedia also mentions football boots.
Which is a good book to refresh discrete maths fundamentals for a grad student? It would be great if the book has short and terse explanations of concepts with lots of worked out examples(/to be worked out exercises) to set the brain rolling. Can someone suggest a similar refresher for graduate level algorithms?
Given two latitude and longitude points, the bearing with respect to north of a great-circle path starting at each point, and the distance between the two points, how can I calculate the latitude and longitude of the intersection of the two paths if it exists?
Can anything be stated about the distribution of the digits of Pi, i.e., if I were to sample n digits of Pi, can anything be said about the probability to observe certain digits, or is there any reason to assume that they would not be evenly distributed? This is purely a curiosity question.
Recently I have considered the following question: for a sequence of i.i.d. random variables(maybe normal distribution), the expectation of the maximum of n such kind of variables is dependent on n, so if n goes to infinity, will the expectation of the maximum of infinite i.i.d random variables be infinite? What is the upper bound of it?
What is a polite way to describe a person as "white-washed", i.e. a person of visible color who acts and talks and cultured the way a white Western person is. Or is white-washed OK ?
So I am filling out a CV and answering about my education, when it comes up 'year obtained' I have never come across this on a CV before and if I have it hasn't been worded this way. Could someone help me? I am confused about whether it asking me the year I started or left, Thank you.
What would be a good term for the subject of a requirement? If one has a requirement applied to them, they would be the [word] of that requirement. I'm looking for something more descriptive than subject or target. Constrained seems like a good fit, but it feels a bit unwieldy?
Is there a non-collective noun for an "instance" of publicity? In other words, a restaurant receives publicity every time a local newspaper publishes a review or an article about it. Each of those articles or reviews are examples of a [blank] for the restaurant?
We know that the ring of analytic function on a connected open set is a Bezout domain. Do we know what happens if we remove the hypothesis of connectedness? It is no longer a domain, but does the ring share the same nice properties like: every finitely generated ideal is principal?
The other day I was talking to a friend about when to use "middle" or "center". I was using it in the context of top, middle, bottom, as a listing, and he suggested it should be top, center, bottom. I want to know whether it should be middle or center.
I have a feeling that this usage - which I personally find highly irritating, because it suggests either that the initiator of a conversation is helping a person who is in dire straits or that they themselves are in trouble and seeking help from a lifeguard figure - became popular in California, but is that correct?
Recently, I am studying Chinese Zodiac Compatibility. They said "Snake (one born in Snake year) and Rat (one born in Rat year) are a volatile pair". I am not sure what "volatile pair" mean? like each person can go to different direction in their life or something like that? or they just do not like to each other See the website here http://www.travelchinaguide.com/intro/social_customs/zodiac/compatibility.htm
What are the Ishibashi states and Cardy states in CFTs? I am familiar with conformal field theory language. It would be great if someone can discuss about the basic idea of these states and their applications.
If a rubber ball is red, I know that it is absorbing all colours except for red, which it is reflecting. So there is not actually a part of the object that contains any red. But what tells an object to reflect the light that it does? Is it something in the surface that does not let that wavelength enter it? Thanks.
I have always wondered and once I even got it, but then completely forgot. I understand that gravity causes high and low tides in oceans, but why does it occur on the other side of Earth?
Which of the following is correct when addressing an audience or more than one person? Or are both equally valid? I hope you have all had wonderful summers! OR I hope you have all had a wonderful summer!
Please forgive my stupidity. So many years after my undergraduate study and so many years after dealing with various concrete ODEs and PDEs, I still cannot tell the essential difference between them. What specific belongs to PDEs but not to ODEs? What conclusion for ODEs cannot be generalized to PDEs? At the moment, my understanding is simply that PDEs have more than one variables.
Is it okay to use ain't in formal conversation? I know ain't can be used for am not, is not, are not, have not, has not. So if I can use it in day-to-day life, it will be easier for me I guess.
As an ESL I'm not sure if I can use the following sentences: You can take no other directions. I'm using it on giving indications to a foreigner. Should I use instead: You can't take other directions. Which one do you think it is the most natural/idiomatic?
Can someone give me some information about this area? PDEs on non-cylindrical domains I take to mean parabolic (let's fixed parabolic) PDEs on domains which evolve in time. What is the state of the art on this topic? What kind of problems do people consider? What tools are used for existence and uniqueness? Any recommended papers?
Sometimes I feel uncomfortable to say "How do you spell xxx ?". It sounds like asking his or her own way of spelling a word implicating that I am not necessarily expecting the correct answer. Is "How do you ... ?" a polite question to ask the right way to do things ?
I'll take the sky diver example. Right when a sky diver jumps out of the plane the net force of the diver is greatest. Then the diver begins to reach terminal velocity where the force of resistance = the force of gravity. So while the force of air resistance increases to equal the force of gravity is the sky diver decelerating?
I am looking for exact or perturbative solution realistic lotka-volterra (the one with logistic term in one of the equations) equations in population dynamics. Any reference where they have done it will be useful.
I'd like to know whether the phrase "where I be" is grammatically incorrect or whether it is correct if in the subjunctive mood. If it is in the subjunctive mood, what exactly would it mean? The entire example sentence is: I look for a place where I be free.
Idiomatically we do say "a strong will". But can we say "strong wills"? The context is The optimism and (the) strong will(s) of the handicapped children touched me deeply. Also, do I need a "the" before "strong will(s)" in this sentence? Thanks.
Does a direct limit of projective need to be projective? And is the inverse limit of injectives injective? I guess they need not, but I can't find an example. Can you help please?
Is this sentence grammatically correct? [This method] binds a handler to one or more events to be executed once for each matched element. source Is it just a contraction of the following sentence? This method binds a handler to one or more events, that is (supposed) to be executed once for each matched element.
Did Feyman suggest even though Q.M. has great predictive power no one will ever really understand it ? Some people have said there may be hidden variables that explain underlying principles of Q.M. but has this been ruled out? Has Q.M. been put in an axiomatic framework?
I have difficulties in using each. Which would be correct in the following sentences? They are each connected to a hydrogen atom/hydrogen atoms. They each are connected to a hydrogen atom/hydrogen atoms. They are connected to each hydrogen atom/atoms. [Assuming that each of them is connected to one H atom.] We each have our own car/cars. [Assuming that each of us has one car.]
After reading the Wikipedia article about procuration, I'm still confused. Here's what I want to know: What does the author mean by "the phrase per procurationem is ambiguous if used with undeclinable English names"? If I sign a letter on behalf of someone, is this protocol acceptable? Sincerely, Secretary's Signature p.p. Account Owner's Name The author implies this method is debatable. What's the debate?
How is the meaning of a sentences affected by chosing one of those words? For instance, what's the different between The screech cicadas reverberated through the forest. and The screech cicadas reverberated throughout the forest.
This is the word problem. If they work together, John and Vince can finish their project in Biology in two days. If they worked individually, it will take John three days longer than Vince to complete the task. How long will it take each to do the job alone? Thanks in advance ;)
In soccer, if a player waits for another player to get into a proper position before passing the ball to him then can I say "That was a nicely waited pass" or would that be grammatically correct?
I see the British normally use plural form of the verbs associated with collective nouns. An example, "The team have fired its coach" versus "The team has fired its coach". I have been told this is slang that has become mainstream. Any idea as to its real origin?
I understand the nature of light can be complex and has extensive theories/experimental data. We hear light can be both a wave and particle, so why can't it be both, a wave of particles?
By this, I mean someone who is not extremely religious, but, in a time of crisis, will turn to religion for hope. An example would be a mother who prays if her daughter is kidnapped, but does not pray on a daily basis. Is there a word for this?
Here are two sentences patterns: Have you ever been to the opera when you lived in Milan? and Did you ever go to the opera when you lived in Milan? What is the difference between them? How can we say, which is right sentence?
My native language has a word for that process hence I am curious to find out if English has one. I searched for it on the Internet without success. Apart from "removing stem", I found "removing leaves" from cilantro.
Assuming inter-universal (see here) travel is possible, can a perfectly mathematically describable universe exist inside a multiverse? If it could, would that mean that the multiverse is mathematically describable as well? (A perfectly mathematically describable universe would be perfectly predictable as well. Can one predict the future of such a universe when inter-universal travel is possible and the multiverse is not perfectly mathematically describable?)
And if so, then why does everybody keep asserting nothing can go faster than light speed (I'm implicitly assuming there could be something which we do not observe, which goes faster than light)?
Consider a solid yogurt. Can we assign a specific state of matter to it? I mean, it behaves like solid. However, if we "mix" it with a spoon, it becomes liquid, or at least in the usual sense. It is also quite plastic, which complicates. My current guess is that it is either a glass or a gel, but I'm quite unsure about it.
Is open mapping theorem true for a analytic function in several variable ? I've encountered a problem, which can be solved easily if that's true. But I couldn't find that after doing some Googling
I am looking for a expression, phrase or word that describes a person or behavior that pretends a mistake made was intentionally done so as to save face. There is a phrase in my language saying "To pretend that the fall was a technique/stunt". I am looking for an equivalent for this in English.
And you may not really expect an answer or want/need an answer. Not quite rhetorical. For example you may be talking about something that happened and wondering who did it and everyone knows who did it including yourself but you ask, 'I wonder who that was.'
Sorry for the daft question, but, is the following a correct thing to say? "The preimage of a function f is a function iff for any element b in the range, there exists exactly one a in the domain such that f(a) = b" "A function is injective iff its pre-image is a function." Thank you.
While showing my work to my adviser, he uttered a sentence, "You could do it better!". Is it analogous to: You could have done better OR You can do it better (so improve it)? It seems to me this sentence can mean both of these.
Is it possible to create a certain design of a conductor to reduce eddy currents greatly? So that the magnetic "breaking" can be reduced? Is it even possible for the force generated by the eddy currents to become negligible?
I know that when some of the previously unsolved problems were solved they created new fields in mathematics. May someone explain to me what would be the result of a major problem like the Hodge Conjecture being solved vs a "smaller" problem like "Do quasiperfect numbers exist?" in today's society. Thank you in advance.
What exactly does a phrase 'we need to take contingency on them' mean? This is an expression I heard from a project manager so I presume it has to do smth with risk mitigation. However, I'd rather not guess. Thanks.
I know there're various types of rhyme in English, such as slant rhyme. There're also things called assonance and consonance. I plan to rhyme "pan" with "screen". Essentially two monosyllabic words ending with "n". Obviously this is imperfect rhyme at best. Is there a linguistic term to describe this type of pairing? If so, what is it called? Thank you.
How would I indicate, for example, that I am going to use "toms" to mean "tomatoes". Something like: Tomatoes (toms) are red. This is false as some toms are green. I like toms.
Is the usage of "though" in the following sentence correct? It's said that it is a picture of a rabbit, but I'm sure enough that what I see is, though, a fish. Don't mind the contents. What I want to ask is whether I can use "though" that way or not. If not, why?
"Small initial discrepancies may not be seen as meet for a federal case, particularly when the employee, trying to succeed in a nontraditional environment, is averse to making waves." Is there a legalistic meaning for meet or did the author mean to use the word meat in the text quoted above?
I dont think so, because then the rays will intersect and the image will be real. Please let me know if you know a case in which a virtual image is formed in front of the mirror.
I ask a question about "What is a wavefront?" which follows the question "What makes the radiation behind a slit coherent". For the wavefront it was answered, that "In electromagnetics ...(that are) the points that are at the same height." Now I'm wondering, are the wavefronts moving?
A lemma in my lecture notes claims, as in the title, given a surjective ring homoromorphism from R to S, ideals in S are the R submodules of S (in the first paragraph - picture attached), but I can't see why this is true. Note that we are assuming all rings are commutative. . Any help very much appreciated
What is (if any) the name of the operation of changing the root of a rooted tree? Picking a vertex which is not the root, then reorienting the edges in such a way that the vertex becomes the root?
I know that through the Abel Ruffini Theorem the general solution to a polynomial of degree five or more cannot be found explicitly. But are there are any other ways to find the roots of such a polynomial besides exhaustive methods like Newton's Method? The question of finding such roots arose when trying to find the the y maximum of the unit lemniscate.
What would you call a triangular object with two sloping, concave sides? See the following image. Consider object A, object B and the entire structure as a whole; object C. What do we call object C? It is related to architecture. I'm trying to describe the structure of an opera house design proposal.
Is it the same as the space of all possible descriptions of a single electron? If not, how do they differ? Please give the mathematical name or specification of this space or these spaces.
What I want to know is: the preimage of an integer by a valuation map is an open set? Otherwise: Can we cover a valuation field by open sets with elements with fixed valuation?
