I have a document with quite a number of figures, some of which have a longer figure caption (in particular some take multiple lines). The image shows such a case: I would like the second and consecutive lines to be aligned with the 'F' from 'Figure', i.e. get rid of the white space below the figure label. The gecko expample from the wikibook (https://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captions) shows this. But they seem to do nothing special to achieve this. Maybe a different software version? How can this be done? Thanks Soraltan
We know that space cannot spread a sound wave as there is no "air" or a medium that would support the spread of a sound wave. However if we put ourselves in the vicinity of an exploding star, would it be possible to hear something? The question arises from the idea that within the explosion of a star (first few seconds or less) you may hear a noise due to the explosion of the star...
For me the relevant number of subgroups of a finite group is the number of non-isomorphic subgroups. Mathematicians seems to have an other opinion. There is a related classification called automorphic subgroups, when there is an automorphism on the main group that maps a subgroup on a subgroup, which seems to be a stronger condition. A weaker condition than automorphic subgroups is conjugate subgroups. What is the relation between conjugate subgroups and isomorphic subgroups? Why isn't isomorphic subgroups more interesting in mathematics?
Given the fact that the force stopping me falling through the ground is the electromagnetic repulsion between the electrons in my feet and the ground, would it be possible to increase this repulsive force? Also is friction generated due to this repulsion of angular faces at a very small scale ? if so could a material be made so smooth it had zero friction because the electromagnetic force simply kept the two apart instead of causing friction? Sorry if its a stupid question but im very interested to find out and why not if i am wrong.
I would like to understand the difference between reflection of light and re emission. Indeed in both case an observer far from the object will se an electromagnetic field coming to him. When we take a perfect conductor an a E.M wave going to it, we know that the wave is "reflected" but can we also see it in the way that the material absorbed the light and re emitted it ? Is the difference based on the fact that in re emission the energy is stored for a finite amount of time in the material and the re emitted as a ray whereas in reflection the energy of the incident beam is never stored by the material ? Thank you for your answers.
Experience and hardship come to mind but they seem too general and they don't communicate the end result. They can be used depending on the context of course but there might be a word for a type of experience that conveys this proverb better. (if not a single word, a two-word phrase). Example sentence: I've suffered through a lot of adversity in my life, experiences that didn't kill me, but made me stronger, turned me into a fighter. These ordeals were (my) _______.
This is a newbie question, but I don't quite understand the forces at work when an object is rotating. So I've read that i can use my right hand to determine the direction of the force at the axis which depends on the direction and the magnitude of a spinning wheel. (Fingers pointing in the direction of rotation, thumb is pointing in the direction of the resulting force.) Does that mean that in a car, the wheels on one side constantly want to fall off, while on the other side they want to move to the enter of the axis?
Suppose that in the future a highly resistant spacecraft went to the Sun and collected three samples of the Sun: one from its surface, one from its core, and one midway. The three samples were put into three high-tech jars which could preserve the samples perfectly (so the temperature, pressure, etc, of the three samples are not altered). The three jars were then brought back to Earth, and exposed into a museum. What would we see? Would the three samples look almost identical to each other? Would they look like some kind of fire/flames? Or would they just look like some kind of boring gas? Please provide pictures if you can.
The word visualization is often used to describe an image or interactive piece of media that represents a data set. I am trying to think if there is an equivalent for something that is not only visual, but also tangible. That is, an object that represents data and that people can touch and see. If there is no word for this, can you think of a neologism for it e.g."tangiblelization"? EDIT: By tangible I mean an object that can you can youch with your hands.
Any action of a finite group on a (non-empty) tree has a global fixed point (in the sense that there is a vertex fixed by all group elements or an edge fixed by all group elements). There is a hint which says we can consider the diameter of the corresponding orbit is minimal. However I don't find the definition of diameter in the book. Can someone clarify the diameter? Or give the details of proof? Thank you.
Why does special relativity exist? Via studying the outcome(s) of such relativity, one can end up with all the equations involved in special relativity. Thus one runs into things such as contraction, dilation, transformations, velocity addition, etc. But these are the outcomes. My question is what is the cause of special relativity, and is the knowledge of this cause currently being shared in the world of physics? Or, to put it another way, is it currently accepted despite there being no cause that is known of, thus an acceptance of an effect without a cause? If you give this question a negative vote, please present your reasoning and or evidence to support such a vote.
This question has been asked before under other guises. I am not a scientific profesional however i have some schooling in pyhsics and mathematics and have a keen interest in these subjects. It seems plausible to me and was a thought i had my self many years ago whilst at college, that the universe could possibly be expanding from within itself. Ie matter and space were expanding at the same rate as each other. I observe there is no relative distance increase between the objects i see on a day today basis and as such this type of expansion wouldn't change our perception of this relatively speaking. Everything we observe would remain the same and we would be unaware of the expansion..
I need a word to describe going out and doing something, which is thought through but not necessarily fully planned. Like all of a sudden thinking "I want to go to a club" while sitting on your couch, then going out and just doing it. A contextual example will be: You're doing nothing and want to do something. You're presented with a list of possible chooses that may interest you. You pick one, and just do it.
My brother asked me this question: You can be disruptive, but can you be ruptive? For example, one can be disrespectful and it is also possible to be respectful... I thought ruptive would have to mean the opposite of disruptive (because...pattern?). I have looked up the definition of ruptive and it seems that both ruptive and disruptive have the same meaning. Why is this so and why is there a distinction if they both mean the same thing? Upon further investigation eruptive and irruptive are also in the same boat. Again why? Is this a common pattern? Examples?
I have been seeing phrases "The board of directors resolved on the budget." but have never heard, and in dictionaries have not found, a combination of "resolve" with preposition "on" to refer to the topic that a body must make a decision on. The OED says to resolve in this sense generally takes an object clause, such as "The Committee resolved that it accepts the chairman's proposal." or "The shareholders resolved to go forward with the takeover bid." But when the actual tenor of the decision is not stated, only the topic on which a resolution must be passed, is it correct to use "resolve on"?
How can an image pass through a window if the atoms in the glass randomly emit photons in any direction? I've read that glass is transparent because the atoms don't readily adsorb visible light, so it passes right through. But then how can a glass lens refract anything if it's not even interacting? Yet magnifying glasses burn ants! I've also read that refraction has to do with the difference of velocity of the wave in different mediums, but I thought that had to do with adsorption also. Maybe it's because a small number of photons get adsorbed and that holds the whole wave back some how? Or is this just another one of those places where classical intuition breaks and you have to go mathy/qm?
Does Gravity / curved space cause rotation? Meaning, if a spaceship is heading not directly toward Earth, but slightly off to one side, and when finally being close to the Earth it falls into earth orbit, does the spaceship continue to point in the same directions as it was when approaching the earth, or does it now rotate at a frequency that is equal to its orbital frequency? I would expect the spaceship to be pointing in the opposite direction after completing one half of an earth orbit.
Well, I guess the 'odds' in 'overcome the odds' means kind of 'diffculties'. But I cannot find such kind of explaining in dictionary (oxford dict online) nor in "Practical Everyday English (by Steven Collins)". The closest explaining, seem to me, is 'The chances, probalility of winning, being successful'. But then it doesn't explain well for the following sentence (from "BBC Life Story") Animals have just one goal at the end of this journey, to leave offspring, and everyone begins its life with an irrepressible instinct to survive and overcome the odds. What does 'odds' mean here?
I have following propositions: p:Grizzly bears have been seen in the area. q:Hiking is safe on the trail. r:Berries are ripe along the trail. I need to convert following compound statement to logical expressions by using logical connectives. If berries are ripe along the trail,hiking is safe if and only if grizzly bears have not been seen in the area What I think is true is: ~p <-> (r^q) Note:I have considered comma in above statement as and. But answer given at the end of book is: r -> ( q <-> ~p )
I used to think that things called "parabolic" must have something to do with parabolas or their defining quadratic equations. In fact, terms like parabolic coordinate, parabolic partial differential equation and so on, are indeed related to parabolas and their equations. But, why are parabolic groups in algebraic group theory (correspondingly, parabolic subalgebras in Lie algebra theory) named "parabolic"? Do they have anything to do with parabolas or parabolic equations? Thank you very much.
My guess is that when you throw a ball, which is held by your hand, using you arm, the radius of the circular path being constant, the outermost part of the ball has a bigger radius than the innermost part, therefore greater linear acceleration for the outermost part of the ball. And so when you release it, the outermost part is always ahead in the direction of rotation than the innermost part.
I am currently studying mathematical course at my college, and I cannot seem to grasp the concept of inequalities. What troubles me is that, like it's said, "triangle inequality matters because many other theorems are dependent of it". But I have no idea why triangle inequality matters, why bernoullie's inequality or why sin function inequalities matter? I would be grateful if anyone explained all of this. Practical examples would be much appreciated.
In my current project we are writing a program to convert a newer protocol to an older one. These conversion programs are being referred to as adapters, but the team cannot agree which spelling to use: adapter or adaptor. I personally plump for adapter, as adaptor sounds like its a person (like actor, realtor, etc.) rather than a device. Is there a case for using one rather than the other?
Is there a name for a pair of words or phrase that can have a double meaning? I was thinking homophones, but I thought that homophones are only applied to single words (ie their, there, and they're). The example: The term "werewolf hunter" can have two meanings A hunter who is also a Werewolf A hunter who hunts werewolves The term "English teacher" can have two meanings A teacher who is English in race A teacher who teaches English Is there a specific term for this kind of phrase?
I am making a video game, and when player tries to walk into wall he should slide along it. However I am confused how to resolve the vectors for it. Here is image illustrating problem: I know the v vector, as well as angles A and B (although angle A is wrongly illustrated here, it should be counter clockwise). How do I find b vector?
It might be a silly question, but one of my friends just got asked this question at an oral exam, and he could not answer it, and didn't receive the answer either (Or at least he forgot). And I've been thinking a while, and I'm not sure what would really happen. If I take, lets say a wedding ring, made from a conducting material, placed it on a table, and turned on an external electric field, what would happen ? The inside of the ring is field free, right ? So does anything even happen, and if so, is it only on the surface of the ring ?
If decoherence time of quantum decoherence is zero, or if off-diagonal elements of density matrix of quantum system (without environment considered) vanished immediately after interaction with environment, then one can say that "classical" probability transition occurred, and this is why we get appearance of wavefunction collapse and measurement. However, decoherence time is almost always not zero, and off-diagonal elements of density matrix of system, as far as I know, do not vanish to zero even though they remain very close to zero. If this observation is correct, then I wonder how quantum decoherence explains how/when measurement occurs - with emphasis on "when".
Since the Lagrangian of our quantum field theories is covariant under Lorentz transformations I'm asking myself if there is any link to some symmetries (like that we get from gauge transformations which also let the Lagrangian unchanged)? So is it possible to apply Noether's theorem to this invariance or doesn't this makes any sense? So what is the mathematically difference between this two transformations and their behavior?
Possible Duplicate: Biblatex: remove commas between last and first names in bibliography Is there an easy work-around with the last-first biblatex macro so that the comma after the last name in the bibliography entry can be removed? The goal is to print Kruse, JS as Kruse JS To see some more background to this question, you may refer to my post: biblatex conditional for printing an extradate.
I'm working on package that (among other things) writes an external file during compilation. I'd like to provide an option to the package to not write the external file. I know I can set up a boolean and test for it everywhere in the package the writes take place. But it would be nice to just set the openout command at the beginning to write to /dev/null or its equivalent. Is that possible? I need to keep this package supported on Windows, Mac, and Unix.
The last couple of days i have been thinking about temperature and heat and i thought : What happens to temperature if i continually supply a particle with energy? Then i thought at sometime i would run out of energy (the energy of the whole universe) so that would be the limit of temperature. But temperature is proportional to the jiggling of the particle but the particle cannot move as fast as light so i used an equation from thermodynamics from Kinetic theory of gases which suggests that: So i figured the limit of Temperature would be : Can you follow this possibly crazy train of thought? Please explain to me: Does temperature have a limit? If so what is it?
I am trying to find the correct opposite of a delegate in the context of a person being a representative of someone else that have allowed or chosen them to be their delegate. What would you call that "someone else?" The only word I could find is a delegator (which isn't a real word in English) or assigner, but they are technical words rather than descriptive. Any other word I could use? Think of it in a sentence like this: Here is a list of all the delegates in the company. But that is the list of their _ _ _ _ _ (what can go here?). I am trying to avoid fillers such as: bosses, agents, managers, etc.
How can I visualize Lorentz transformations? I know it's four dimensional, but without a visual picture in my mind I can't understand any of this. For example how do: Time reflection Space reflection Proper Lorentz transformations Improper Lorentz transformations Homogeneous Lorentz transformations Orthochronous Lorentz transformations Antichronous Lorentz transformations look like? I don't have any idea about how they look like. Maybe this can be explained with Minkowski diagrams or in some other form.
Question: If air was significantly compressed, and then the force compressing it suddenly disappeared (no container), what would happen? Side Question: I'm imagining significantly compressed, but what kind of pressure would be necessary for that? Thoughts: It has been a while since I took chemistry and physics, but what I think is that it would rapidly expand and exert similar pressure to whatever the container was exerting on it in all directions? So similar to what an explosion from heating gas or what not would do?
In my dialect of American English, the word "tush" or "tushy" is a dimminuitive of "rear end" (e.g., something you'd say about a baby, not as harsh as "butt" and a word you aren't ashamed to say to your mother). The word derives from Yiddish, and I am from a Jewish family in the New York area, so I'm generally understood when I say it. How broadly is this word understood? What do folks who don't use it say in its stead?
What is the best strategy to survive a free fall naked out of a jetliner at cruising altitude (ignoring temperature)? For instance, my strategy would be to streamline my fall so that my terminal velocity was very high. Then at some critical distance above the ground I would pitch upward and attempt to use my forward velocity to achieve lift. Presumably this would slow my fall to some survivable speed. (This is roughly what the space shuttle does after all.) Would it work? And idea if it would be survivable?
My question is this: suppose we create two different standing waves in a string . So, is the energy of the standing wave dependent on the frequency of the wave ?(assume that the amplitude is unchanged) My guess is this: the energy of the standing wave is equal to the sum of the energy of the individual waves. Since the energy of individual waves remain the same( as the amplitude is constant) , the energy of the standing wave remains constant too. Am I right?
What do you call the practice of using (overly) complex words specific to a subject? I am thinking of scientific or academic fields where the common terminology used in the field is very unapproachable to someone not in the field. The situation I am imagining is when one professor gives a lecture using field specific language and the topic seems very difficult to approach to the lay person. On the other hand, another professor may give a lecture conveying the same information using terminology and phrasing easily understood by outsiders. Is there a word to describe this difference in style practice?
"I would like to talk today about what I think is one of the greatest adventures." In this sentence, is "what I think" is used like this "I would like to talk today about what, I think, is one of the greatest adventures." or like this? "I would like to talk today about what I think is (the thing I think is) one of the greatest adventures." Any explanations please? Which is correct?
I was going through the book HANDBOOK OF PRODUCT GRAPHS by Richard Hammack, Wilfried Imrich, and Sandi Klavzar. In the preface section, application of direct product of graphs is mentioned. I am interested in gaining more information about the real life applications of other graph products. Can anyone suggest me a link or good book as a reference? This will be very helpful to me. Thanks a lot for giving time.
I am interested on drawing (I suspect that using pgf/tikz is one of the easiest ways to accomplish this) a picture like the following one It is supposed to be a grid of the plane (I only care about the points with natural coordinates), where there are some "red bags" which contain some of these points , and there is a region that is coloured on yellow (one of the red bags corresponds exactly to the points in the yellow region). Any idea about how to use pgf/tikz to draw something like this?
The following sentence is from a mathematical lecture note here: It takes a little bit of getting used to the idea of a function that cannot actually be evaluated at any specific point, but with some practice you will find that it will not cause any significant conceptual difficulty. Is there anything wrong with this sentence? I guess it is supposed to be "It takes a little bit of time for getting used to the idea...". Any idea for understanding the sentence?
I would like to know about the larger picture, current state and future prospects of the sequence of papers that were written by Sheldon Katz and Cumrun Vafa on F-theory. (Freddy Cachazo was also a co-author in many of these papers) I guess the same is also known as "geometric engineering". (Kindly explain if that is not the same) There have been recent works on F-theory by Cumrum Vafa, Jonathan Heckman and others. I would like to know of how this recent work fits in with the earlier work by Katz and Vafa and where do people see this pursuit to be going and what does the community think of its future prospects. Are these Katz-Vafa works a prospective field for beginning grad students?
Lots of people have wondered why English seems to be one of very few languages with such irregular spelling, far from its pronunciation. The answers include the Norman invasion, and the Great Vowel Shift. Ok, cool. But why did all those other languages not have the same thing happen to them? German, Spanish, Italian, all Slavic languages, etc. They don't have a silent 'e', they don't have the day/date poke/soak treat/tree vowel dualities, etc. They still ascribe vowels the same sounds they ascribed them many centuries ago. Is it because England had more trade contact and colonies? Or because they're on an isolated island? Or why?
I'm trying to figure out the angle between the direction to an objective point relative to a player looking a certain direction. This will be used in making a direction indicator for a game. Here's a diagram made in Geogebra that shows the scenario Updated diagram to avoid confusion I have X,Y coordinates of the player and objective and I have the rotation of the player to work with.
Say, you buy some new office furniture. You get the furniture parts delivered including the service to put the different parts - for example the desk top and the desk legs - together to complete furniture ready for usage. Is the person who carries out this service called "Assembler", "Installer" or "Fitter" and is his service called "Assembly", "Installation" or "Fitting"? Are the words interchangeable? Do they have different connotations? Are there other contexts where they are not interchangeable?
I am searching for math competitions for college students. Of course I am familiar with Putnam, but I am looking for a lower ranking competition. Either US-national or regional (South/Texas). I tried this list but my first three links were stale. So I thought I ask a live audience. If you have organized such competitions for your students I would like to hear your reviews and rankings. Also, if you have used high school-level competitions for university students I would like to hear your views about that as well.
