What are the long metal things in stores like Walgreens that hold things like gummy bears or nuts or hair clips? The metal things are straight and then at the end they curve up, and they are connected to the wall to carry things without using shelves.
Why when a person is standing still on a floor we say that the force that this person acts on the floor equal to it's weight? , Isn't the weight the force that the earth pulls the person and acts only on the person, how then this force goes to the ground ?
My teacher told me that in anode ray experiment the electron were emitted from the gas present inside the vacuum tube and the ionized electron form cathode ray and ionized gas form anode ray. So I wanna know thus atoms present inside the vacuum tube were fully ionized and only their nucleus remain? So for my bad English.
From a point just north of the equator, A straight line to the Magnetic North would be through the earth. If a compass was turned on it's side, would the north pointing arrow point toward the ground along that straight line?
I know that currently dark matter and dark energy are separate things, not related and one not deriving from the other. But if both are included in a generalized gravitation theory, the picture can change. Then there may be a correlation between the dark matter and dark energy, and they may then have a common origin.
thank you all. I can translate from language to another manually. Are there any way to translate a lyx document, for example, from English to Arabic in the same way as in a Word document such that the mathematical expressions remain as they were? I want do this automatically by a lyx function if possible.
I have a hexagon with interior with the opposite sides being identified. In order find the identification space I did the following cutting and pasting. My question is : Is it correct way to do the identification? I have heard cutting is not a continuous operation. That's why I am confused. Could anyone give me some suggestions in this regard? Thanks for your time.
Modulational instabilities occur in waves which occur in nonlinear system. A linear stability analysis is done to examine the dynamics in the short-time regime to observe the structures which spontaneously form. What methods are there for examining the structures in the nonlinear regime?
The focus on the exterior of a building alone will lead to the increase in construction cost, making such an endeavour unjustified. I want to know about the grammatical structure of this part: making such an endeavour unjustified.
All chapters begin a new page by default. I want to remove this break between two short chapters. By the nopagebreak doesn't work. What can be the cause? Is there another way to do that? I don't give all my code there, but I can write some details if needed.
I already posed this question Negative energy solutions in Klein-Gordon and Dirac equations but I am not satisfied with the answers. Trying to be very sharp: does Klein-Gordon equation have negative energy solutions like Dirac one or are they (the solutions) somehow different? if they are the same, why the problem of negative energy is always referred to Dirac equation and not to KG?
In my complex analysis course I'm supposed to compute all entire functions with the given requirement for the Real part. How do I work on this? I hav no clue how to work this out. Can someone please give me a hint?
MPM combines elements of both the finite element method (FEM) and the particle-based methods. It is particularly suitable for problems involving large deformations or fluid-solid interaction. Would you apply it (after proper editing) to wave propagation problems, where there is no mass transportation, but only energy transportation?
How does protons collide and produce heavier particles if light particles can not decay into heavier particles ? considering particles can not decay into heavier particles irrespective of their energy. How can we see heavier particles at CERN if only the protons are colliding ?
I am doing a course on rotational movement of solid rigid objects and a professor of the MIT symbolizes the axis around which the object rotates with a symbol that is a letter with a vertical line on top of it and another one below it. Is there a simple way to do that in a line of LaTeX?
"In physics, gravity is a fundamental interaction which causes mutual attraction between all things that have mass" "Light or visible light is electromagnetic radiation that has no mass" My question is how can gravity swallow light ?
What do you think is a suitable word to use instead of the informal "stuff" here, and is "appropriate" used correctly in this context? I will give you the number of the appropriate team that will be able to help you with questions with regard to administrative or financial [stuff].
In English, when speaking about going to the center of the town, it's a matter of going to the "downtown" so, my question is about the origins of the connotation of some "descent" (going down) - moreover, I noticed that the same phenomenon is present in many other languages...
"As we look on on the conflict" I want to use the phrase "look on" but am not sure how to incorporate it into the sentence. Would be "as we look on at the conflict"?
Is there an adjective of intensity (or similar term related to force) that ends in "-al"? like: space > spatial, time > temporal, etc. Intensity is meant as the physical attribute/dimension of some physical phenomenon. Sample sentence: "... the high (...adjetive of intensity needed here...), temporal [adjective of time], and spatial [adjective of space] resolving powers of macroscopic observations require that ... "
I am new to topic " Algebraic Grid Generation". I want to find a simple example where we solve the host equation, let us say the heat equation, numerically in the computational domain then transform it back to the physical domain. All the references I found discuss the general steps without providing a single practical example
What does "which" refer to in the following sentence? The final jurisdiction over what an intellectual is resides in culture, which becomes almost coterminous with a singular public opinion.(https://dictionary.cambridge.org/ja/dictionary/english/coterminous) I think it refers to an intellectual, but I'm not sure.
Like in adiabatic process there is closed system but in reality we know there is no such thing as closed system there will be still exchange of heat so it will not work adiabatically means it is only applicable for ideal gas not real gas?
I would like to know if it is possible to use the Concrete font together with the standard LaTeX mathematical font. If it is possible, could someone please tell me how to do this? My thanks in advance!
You encounter them periodically in movies, and, in certain places, in real life. I asked people who live in a region positively studded with castles, and all they could come up with was "the peeping slidy thingy in the entrance door." Which is amusing but doesn't answer the question. What's it called? And the slide - does it have a separate term?
A friend said something to their dog and it was meant for me. I told her that I am pretty sure that is passive aggressive, but don't think I am correct. What is this called? I attempted wording it several different ways, but continually received links that were not applicable.
Such as the natural linewidth is defined to be angular frequency, while the absolute frequency of laser is frequency. By far I haven't found a good way not to learn it by roting. Would anyone be willing to share with me your thoughts if you have a better way?
i am confused about a result in paper related to reflectivity from etched hole in silicon. The reflectance oscillation varies with surface roughness but i am not getting similar oscillation while simulating in fdtd lumerical. the model paper is based on fresnel equation.
It is possible to get quadrature squeezed light where on one quadrature the uncertainty is less than the of a coherent state while in the other one, orthogonal to it, it is larger. Is it possible, by doing an appropriate angle transformation, to go from a quadrature squeezed state to a photon-number squeezed state (sub-Poissonian distribution)?
I have a feeling that the word "ingredient" implies that it was intended to be there by human, while catechin is not an additive, but was naturally in the tea leaves. Giving another example, is polyphenol a healthy ingredient of wine, a composition, or a compound of wine?
I believe that electric current is a kind of force (even when we consider it to be opposite to the flow of electrons). If it is so then what is the nature of this force ? And also tell me if there are energy carriers in that constitute this force.
I've learned that the Hamiltonian Operator corresponds to the total energy of the system when applied to a general wave function. After applying and obtaining the measurement (energy), the wave function turns into the eigenfunction. Does the wave function before the operator is applied have to be an eigenfunction of the operator, or can the operator be applied to any wave function?
An interior point of an equilateral triangle ABC is M. The projections of M on the sides of the triangle respectively: points E, D, F. Let G be the centroid of the triangle EDF. Prove that G is the midpoint of OM if O is the circumcenter of triangle ABC.
I remember author of some textbook alluding to Zassenhaus and Knuth's bound of the zeros of a complex polynomial.Unfortunately after even after days of search I could not find some reference or source for it.I would be highly obliged if somebody could provide some source
Assuming that there is no form of resistance in the primary circuit, and that the secondary circuit contains resistance, will current in the primary circuit be infinite? Will resistance in the secondary circuit provide resistance in the primary circuit? Thanks in advance.
I came across a problem where a piston and gas arrangement was present and it was heated, so if the piston is free to move we call it isobaric. But is it only true if it is quasi static (reversible process) or also for a normal irreversible process, and if not will that process be some polytropic process.
This is from a test: What on earth have you done to your hair? Oh. I've had it cut, do you like it? I am wondering if the comma after "cut" is justified. Would a period, dash, or semicolon be better in its place?
Regarding linearly polarized electric fields that are produced by a dipole antenna and electric fields from a current carrying wire, are the equipotential surface the same as the magnetic fields? Because both are perpendicular to the electric fields.
I am writing a document using overleaf and spellcheker underlines all words with red, it looks like this: How can I fix it? By some reason it did't underline all words in other documents that I wrote.
I know that random forcing does not add unbounded reals. Is a Cohen real always unbounded? I can proof that the product of two random forcings adds a Cohen real. How can I show that the two step iteration of random forcings does not add cohen real?
Is the equation T=M/F where T is residence time, M is quantity and F is flow rate equivalent to W=L/lambda where W is waiting time, L is queue length and lambda is flow rate? It seems to me that the derivation of either equation would be equivalent to the derivation of the other.
I read a previous question "superconductor levitating in earth's magnetic field?" it seemed like the impact of gravity would make this unikely unless the superconductor was super light. Is it conceivable to combine the properties of aerogels and superconductors to create light material that repels the earth's field? basically is the synthesis even possible? and if so what might it require?
Programmer here. I sometimes catch myself saying that something is a Tautology False because it always evaluates to FALSE or OFF. I know Tautology means always True in discrete math but I use it to describe something that doesn't change. It's always constant in being False or Null, etc. Am I being illogical.
By default the hyperlink in the list of acronyms is in the page number. Is there a way to change this such that by clicking on both the acronym and page number it takes you to its first occurrence? Kind of like using linktoc=all in for the table of contents.
when I look up into the night sky I see planets, not twinkling like the other stars, but still illuminated. However, when the Hubble or James Webb telescopes approach planets we see the local features instead of an illuminated sphere in space. why is that?
I am looking for the very first published experiment in a relevant journal with all the following features: Michelson or Mach-Zender light interferometry is demonstrated The arms of the interferometer are optical fibers The light used is a slow sequence of single quanta (aka single-photons) generated with on-demand methods (e.g. Quantum dots). Does anyone know the reference of this article?
A red light and blue light enter a rectangular glass block normal to its surface at the same time. Strictly speaking, after passing through the block, which pulse exits first? Should I consider their paths inside glass slab to be same as the lights are entering normal to the surface?
I am building an online LaTeX editor and now face issues with slow compilation for documents of increased size. Everytime the user changes the document, the compiler has to recompile the whole document. Is it possible to only compile the changed part and speed up compile performance that way?
I know a and l, and that the dotted lines are parallel, how can i determine the angle alpha in terms of a and l? I've been working on it non-stop for the past two days and I can't find a solution, although my system seems fully constrained. Figure
The magnetic field is pointing upwards and uniform. Part C: Since the magnetic field does not do any work, the initial velocity of the bar should remain constant through time. But in the solution of the problem, the velocity is a function of time. Can anyone please explain this inconsistency?
I would like to use something that looks like the following table in my document, but I have no idea of how to make this using TikZ or other packages. Using a matrix leaves too much empty space above in my tries. The cells should be editable, so I can show the parsing steps.
Please could someone help explain to me the choice of delta here. I am unsure how the definition of uniform continuity is being applied. I guess it is something to do with when x and u fall in different intervals J or I? Thanks for your help!
While i'm doing the math homework, I find something very strange. I am confused by a textbook's answer. The Question The textbook's answer So, Does differentiation change the units of measurement in mathematical equations?
Is there a word for "a diverse amount of knowledge"? I would be used in a sentence like this: Trying to give a diverse amount of knowledge covering many fields and genres of text.
Electrons have a magnetic dipole moment. If a permanent magnet was held against one end of a copper rod, the delocalised electrons close to the magnet would be attracted and concentrate around the magnetic pole. This should result in the creation of a weak electret because of the uneven electron distribution.
As in, is there a manual for how to get good typography using the LaTeX typesetting system that is similar to Matthew Butterick's web-based book? MB's Practical Typography only shows examples for web, MS Word and Pages which is why I'm asking. That website is linked here: https://practicaltypography.com/
Which statement is correct? The change adds more info to the changelog about the previous commits on May xx, xxxx. Or: The change adds more info about the previous commits on May xx, xxxx to the changelog.
The problem I have is that the line around which the circle must be rotated cuts the circle in two parts. Any hint or help with what to do with it will be useful. Thanks.
I just don't understand how the voltage is adjusted to suspend the droplet. What do we use to adjust the voltage? Because, normally, even when electric and gravitational forces are balanced, the charge will moves with uniform velocity towards the oppositely charged direction.
I see a lot of books of Nonequilibrium QFT and they study the thermodynamics on quatum realms, but what is the difference about that and Quantum Thermodynamics? They study the same thing only with different approach?
Needs to prove that integral can be reduced to another form with specific substitution. Not sure how it can be proved. I think that t=sin(phi) on second stage but I can't understand how to start.
I want to see and compare all the beamer outer themes. Something like this. Is this available somewhere? I know I can generate examples myself, but I prefer to use something already available.
In the below sentence, The mission of the entity may include goals other than maximizing profit. is it implied that "maximizing profit" is a goal of the entity OR is it referring to only non-profit-maximizing goals?
I am student of mathematics and I have started to learn algebraic topology . I want to learn visual things . Can you please suggest books that can help me to increase visualization ?
Can Sagnac effect be observed in coiled, rotating electrical cables conducting electric signals, in a similar way to that observed in coiled, rotating optical fibers? And if so then who demonstrated it first in electric cables?
Consider a gas. Now, we already know the particle's duration of a collision is very small and it immediately bounces away from there. Can these be thought of as topological holes in one's phase space (since the particle barely spends anytime there)? What is the volume of these holes and do they obey extensivity?
Some people say that when the electrons are excited beyond the Mott gap, the electrons will just hop to the neighbor ions and stop there so will not contribute to electrical conductivity. Is this true?
One to the power of infinity seems to be undefined. Is the infinite power tower of one also undefined? EDIT What about one to the power of the cardinality of an infinite set? Does that do away with the issue of the (alleged) undefinedness?
Can we say the ability of computers to make decisions is based on a quantum property? I refer to the PN junction in semiconductors, is the phenomena related to PN junction a quantum property? Why I asked that, I wanted to know if the finest element able to make a decision is necessarily at quantum level. In example can we make a choice mechanically?
I know in an isosceles triangle, the height, median and angular bisector to the base are coincidental by SSS or other congruent theorems, but I searched all over the world and can't find whether there's a name for this property.
If object A's momentum is decreased, will it produce less force on object B upon collision, in comparison to a situation where A object had greater momentum? If this is true, does it follow that the velocity of an object is proportional to the amount of force it can produce on another object?
In this Penrose diagram for a charged/Rotating black hole, once your in the new universe you can continue onward to an infinite sequence of black holes/white holes. So I'm asking, where do those black holes and white holes come from?
When water is absorbed by soil for example, it gets dark. But when water is absorbed by tissue paper, and kept closer to another object, that object can be seen pretty clearly through the tissue paper. Isn't it possible that soil becomes translucent and the tissue paper becomes darker in colour?
I have seen that the electric field of a dipole antenna detaches and propagates. For a section of the detached electric field, will the antenna experience recoil if the detached field moves a charged object?
Ball is free to move in hollow tube, if you rotate tube ball will move outward. What force push ball outward in inertial frame and how ball trajectory looks? (I know that centrifugal force don't exist in inertial frame, but without this force I can't explain what force move ball outward...)
Ligo works by destructively interfering light from a laser using an interferometer. Its said that no light enters the photo detector when all mirrors are the same distance. However,based on my research,the light would just create an interference pattern and never completely destructively interfere. How exactly does ligo do this? Can I get it done on a smaller scale?
I am new in the community. I am reading the book "Linear models in statistics" of Rencher & Schaalje. Can someone argue if that's correct? How can you express "some simple sum of squares as quadratic forms in y"? picture from book "Linear models in statistics"
if a matrix A is m by n , and m>n , in this case we have one solution? i don't understand how more rows of a matrix can still have one solution
Hoping for some assistance with my possessive conundrum. If you were going on a trip for leaders (not run by leaders/organised by leaders), would it be: a Leaders Trip or Leaders' Trip? Thank you!
I am writing lyrics to a song, and the first two lines I have written read as follows: The spiral begins as these thoughts are imbued, "I'm hideous sin and I have no value." The idea I want to convey is the negative thoughts that saturate or permeate a person causes a downward spiral that can lead to despair.
The existence of Magnetic monopoles has not been proven or disproven. There are equartions for Charge black holes, There are equations for Rotating black holes, but are there equations for Magnetically charged black holes?
We say "I had to leave," but not "I'd to leave." Why? This is also unlike other auxiliary usage of the verb "had" (e.g. in past perfect tense), so the difference is more nuanced than the had being an auxiliary verb or not; why is this not contracted like other auxiliary usage of the verb?
Examples: I can throw a good throw. I want to run a long run today. Scoop me a scoop, please. She gave me drinks to drink. I really like these simple sorts of sentences, but I've never seen any specific term for them.
If I am taking takeout home in a plastic bag, is it better to remove all air from the bag when sealing it so no heat is lost to the surrounding air or keep air in the bag acting effectively like insulation? Let's assume the air is room temp/colder when I seal the bag.
The Theorem on the Textbook Is there anyone who can explain the theorem to me. I find it hard to understand. Thanks! By the way, what's the formal name of this theorem, I found nothing online.
Do you have interesting books presenting abelian variety (over an arbitrary field k) using the scheme point of view? Most of the lectures I know use the point of view presented in the first chapter of Hartshorne (so without scheme). I'm looking for something which presents the modern aspects/questions of those objects.
How to find the lateral surface of elliptical cone? Equation of lateral surface is Lateral surface equation but how to find the value of E in this equation? Here is an example. Example
Why does a rotating body, like a rod or a spring, exhibit elongation instead of compression even though every part of it experiences "centri-seeking" force? Is it plausible to understand this in an inertial frame of reference, rather than the conventional pseudo refrence frame?
While it's not too difficult to derive Snell's Law for acoustics e.g. from Huygen's principle like for light, I find surprisingly little resources on an equivalent to Fresnel formulas linking the reflected and refracted amplitudes, mostly limited to perpendicular incidence and sound intensity in dependence of acoustical impedance, but what are the formulas for e.g. pressure or density continuity at arbitrary angles of incidence?
If A and B are two normal matrices with the same eigenvectors, but different eigenvalues, where, A = UVU' and B = UWU', which operations with A and B (sum, multiplication, inverse, etc,.) will change the eigenvectors of the resultant matrix and which will not?
