This question was answered here previously but i am re asking it since it a was no explained in detail I actually want to know the energy stored in electromagnetic waves move to the electron and gets scattered in different direction(Thomson scattering)how cum energy stored in field moves to the electron does the electron create opposite em wave which cancel the original wave so energy is bsorbed or any differnt phenomenan takes place please explain in detail
I was wondering how light or any electromagnetic radiation can be "absorbed" if it consists of electric and magnetic fields. For example if there is a charge at point A, and the  light reaches point A, it will cause that charge to move depending on the value of the electric field. However, why wouldn't this electric field continue on and influence others particles everywhere else? For example, if you have a static charge creating an electric field, then if you put a charge at point A it will feel its effects and then if you bring a charge at another location B it will also feel its effects, namely it will not have been absorbed. Please shed some light on this. Thanks  edit: Does this mean the electron that absorbs this light moves in such a way that it creates an electric field of its own canceling the initial one? Or am I way off?
My question is the same as .

Good luck! How to make a persistent live Ubuntu USB with more than 4GB I want to make a persistent live Ubuntu USB drive with more than 4GB of storage.   I know there is an option of installing directly on the drive but I don't want to do this as it will restrict the drive from working on different computers.   One option is to make an additional partition with extra space but if I do this how can I get newly installed software to be stored on this partition?

How to understand the combination formula? I'm reading an algorithm book. In which it mentioned:     Imagine (once again) you have n people lined up to see a movie, but   there are only k places left in  the theater. How many possible   subsets of size k could possibly get in? That’s exactly $C(n,k)$, of   course,  and the metaphor may do some work for us here. We already   know that we have $n!$ possible orderings of  the entire line. What if   we just count all these possibilities and let in the first $k$? The only   problem then is  that we’ve counted the subsets too many times. A   certain group of k friends could stand at the head of  the line in a   lot of the permutations; in fact, we could allow these friends to   stand in any of their $k!$  possible permutations, and the remainder of   the line could stand in any of their $(n–k)!$ possible  permutations   without affecting who’s getting in. Aaaand this gives us the answer!       $$C(n,k)= \frac{n!}{k!(n −k)!}$$      This formula just counts all possible permutations of the line (n!),   and divides by the number of  times we count each “winning subset,” as   explained.   I'm not quite understand why the reminder can in any $(n-k)!$ permutation, if he stands at the end of the queue, won't he let all these people in?  And why I should use $n!$ to divide by $k!(n-k)!$ ? Didn't see that consequence from the metaphor.  If you have better ideas to explain this formula, you can use them of course. Get the real width and height of an image with JavaScript? (in Safari/Chrome) I am creating a jQuery plugin.  How do I get the real image width and height with Javascript in Safari?  The following works with Firefox 3, IE7 and Opera 9:  var pic = $("img")  // need to remove these in of case img-element has set width and height pic.removeAttr("width");  pic.removeAttr("height");  var pic_real_width = pic.width(); var pic_real_height = pic.height();   But in Webkit browsers like Safari and Google Chrome values are 0. For every set $A$, the empty set is a subset of $A$. The empty set is a set. Therefore, the empty set has a cardinality $\geq 1\ldots$ How is the value of $\pi$ ( Pi ) actually calculated? When I was a child I was taught $\pi$ (Circumference/Diameter) is an irrational number  and can be approximated to $22/7$ but $= 3.(142857)(\ldots)$.      But where does this value comes from?  In short How do I derive $\pi$? Java; String replace (using regular expressions)? As part of a project for school, I need to replace a string from the form:  5 * x^3 - 6 * x^1 + 1   to something like:  5x&lt;sup&gt;3&lt;/sup&gt; - 6x&lt;sup&gt;1&lt;/sup&gt; + 1   I believe this can be done with regular expressions, but I don't know how to do it yet.  Can you lend me a hand?   P.S. The actual assignment is to implement a Polynomial Processing Java application, and I'm using this to pass polynomial.toString() from the model to the view, and I want do display it using html tags in a pretty way. While revising for exams, I came across a question where at the end of it, we had to determine whether the below series was convergent or divergent:  $$\sum_{n=1}^\infty \frac{(-1)^n}{n(2+(-1)^n)} $$  Unfortunately, other than knowing that as the series $ \sum_{n=1}^\infty \frac{(-1)^n}{n} $ converges, this series will most likely converge as the $(2 + (-1)^n)$ terms are bounded, I can't see a way of using this to determine if it converges or not.  Here's a list of some of the other ideas I've tried, which don't seem to get me anywhere:   Generalising the series - By this, I mean replacing the $-1$ for $z$ and then try and use the ratio test to see whether $-1$ is inside or outside or on the boundary of the circle of convergence - however, when I did so, I believe that the ratio test is inconclusive for all values of $|z|$, which while disappointing, is an interesting feature of the series.  - While this is usually a nice tool to use for when dealing with awkward sums, I can't see any good choice of sequences $ (a_n) $ and $(b_n)$ to choose to use. Summing consecutive terms - By this, I mean evaluating the series by looking at the sum of    $$\sum_{k=1}^\infty \frac{(-1)^{2k}}{2k(2+(-1)^{2k})} + \frac{(-1)^{2k-1}}{(2k-1)(2+(-1)^{2k-1})}$$  $$ \Rightarrow \sum_{k=1}^\infty \frac{1}{2k} - \frac{1}{3(2k-1)}$$  $\quad$ but then as we are left with parts of the harmonic series this doesn't seem like a nice way to  $\quad$evaluate it.  Other than that, I'm completely out of ideas, so any new ones (or ways to make my old ones work) would be much appreciated! Is there something like python's interactive REPL mode, but for Java? Is there something like python's interactive REPL mode, but for Java? So that I can, for example, type InetAddress.getAllByName( localHostName ) in a window, and immediately get results, without all this public static void nightmare() thing? Why do cars gain lift while going at a high speed? I've been researching the physics involved with spoilers and I've just been turning up the same information about spoilers giving the back wheels of a car more traction by acting as an up side down airfoil.   So my question is, what exactly causes the car to apparently gain lift while moving quickly, so as to merit the use of a spoiler, and is this entirely due to the aerodynamics of the vehicle in question?   Edit: Clarity of question. Exporting QGIS contour attributes in DXF file? I have a .tiff data file that generates contours in QGIS. I save it as .dxf. The contours don't have any attributes or data. That's bad, because I want to make a 3D landscape in Revit using the information.   How do a save/export the contour lines from QGIS so that they have a z-elevation attribute or at least some information?    I ticked the attributes box when extracting the contours, but the attributes doesn't show in the dxf. EU flight compensation distance for connecting flight I recently had a flight from Valencia to London, going through Düsseldorf, cancelled. According to EU regulations there are different levels of compensation for flights below and above 1500 km in distance. I assume that this distance refers to start and end airport regardless of connection. Is this the case? I haven't found a proper definition online. Here, it would make a difference as VLC to LHR is around 1350 km, but the complete itinerary is above the 1500 km threshold. Have red shifted photons lost energy and where did it go?

Connect to a MySQL server over SSH in PHP Exporting animation created with animate package Consider the following minimal working example.   It's great to have an animation in pdf format.   But sometimes it would be good to be able to export it into an animated gif or something else (swf, video file, svg?).  How do I achieve this?   Note: I often have animations together with pgfplots.     \documentclass{article}  \usepackage{animate}  \usepackage[active,tightpage]{preview} \PreviewEnvironment{animateinline}  \begin{document}  \begin{center} \fboxsep1mm     \begin{animateinline}[autoplay,loop]{2}     a     \newframe         b     \newframe       c                      \end{animateinline} \end{center}  \end{document}   Remark   The animation is not visible in all PDF viewers. It surely works with a current Adobe Reader. I read (or do I say "have read"?) many rules for when to use the present perfect. I found them complex and hard to understand (or do I say "have found"?). I am finding it hard to apply these rules in real sentences.  Is there a simple and clear way to explain the difference between past simple and present perfect? If there is a simple explanation, please tell it! If there is no simple explanation, please tell why it is so complicated. Maybe if I knew why there is no simple explanation, that would help me understand what work I need to do in order to learn the difference. How to move files to specific folders based on CSV entries?
