Best books for mathematical background? I'm developing a multilanguage software. As far as the application code goes, localizability is not an issue. We can use language specific resources and have all kinds of tools that work well with them.  But what is the best approach in defining a multilanguage database schema? Let's say we have a lot of tables (100 or more), and each table can have multiple columns that can be localized (most of nvarchar columns should be localizable). For instance one of the tables might hold product information:  CREATE TABLE T_PRODUCT (   NAME        NVARCHAR(50),   DESCRIPTION NTEXT,   PRICE       NUMBER(18, 2) )   I can think of three approaches to support multilingual text in NAME and DESCRIPTION columns:   Separate column for each language  When we add a new language to the system, we must create additional columns to store the translated text, like this:  CREATE TABLE T_PRODUCT (   NAME_EN        NVARCHAR(50),   NAME_DE        NVARCHAR(50),   NAME_SP        NVARCHAR(50),   DESCRIPTION_EN NTEXT,   DESCRIPTION_DE NTEXT,   DESCRIPTION_SP NTEXT,   PRICE          NUMBER(18,2) )  Translation table with columns for each language  Instead of storing translated text, only a foreign key to the translations table is stored. The translations table contains a column for each language.  CREATE TABLE T_PRODUCT (   NAME_FK        int,   DESCRIPTION_FK int,   PRICE          NUMBER(18, 2) )  CREATE TABLE T_TRANSLATION (   TRANSLATION_ID,   TEXT_EN NTEXT,   TEXT_DE NTEXT,   TEXT_SP NTEXT )  Translation tables with rows for each language  Instead of storing translated text, only a foreign key to the translations table is stored. The translations table contains only a key, and a separate table contains a row for each translation to a language.  CREATE TABLE T_PRODUCT (   NAME_FK        int,   DESCRIPTION_FK int,   PRICE          NUMBER(18, 2) )  CREATE TABLE T_TRANSLATION (   TRANSLATION_ID )  CREATE TABLE T_TRANSLATION_ENTRY (   TRANSLATION_FK,   LANGUAGE_FK,   TRANSLATED_TEXT NTEXT )  CREATE TABLE T_TRANSLATION_LANGUAGE (   LANGUAGE_ID,   LANGUAGE_CODE CHAR(2) )    There are pros and cons to each solution, and I would like to know what are your experiences with these approaches, what do you recommend and how would you go about designing a multilanguage database schema. If $A = \tan6^{\circ} \tan42^{\circ},~~B = \cot 66^{\circ} \cot78^{\circ}$ find the relation between $A$ and $B$ My trigonometric problem is:     If $A = \tan6^{\circ} \tan42^{\circ}$ B = cot$66^{\circ} \cot78^{\circ}$ find the relation between $A$ and $B$.    Working :   $$B = \cot 66^{\circ} \cot78^{\circ} = 1- \frac{\tan24^{\circ}+\tan18^{\circ}}{\tan42^{\circ}}$$  $$A= \tan6^{\circ} \tan42^{\circ} = 1- \frac{\tan6^{\circ} +\tan42^{\circ}}{\tan48^{\circ}}$$  but it seems  this is the wrong way of doing this...please suggest. Thanks! Should the weight of downvotes be increased? What regex pattern would need I to pass to  java.lang.String.split()  to split a String into an Array of substrings using all whitespace characters (' ', '\t', '\n', etc.) as delimiters? What are best practices for choosing and pairing fonts? I've always found font selection to be a little bit of a mystery. What factors should be considered when choosing a font? How does one successfully incorporate two fonts into a design?  I realize that some factors will include things like:   Legibility Scalability Appropriateness/Mood/Emotion   However, how does one objectively judge legibility or appropriateness? Are there objective principles that can be applied for font selection? If possible, please list resources or examples in your answers. Studies focused on the effectiveness of different fonts would also be extremely useful. Flirtatious Primes Here's a possibly interesting prime puzzle. Call a prime $p$ flirtatious if the sum of its digits is also prime. Are there finitely many flirtatious primes, or infinitely many? Why do microcontrollers have so little RAM? Maybe this is more of a perceptional problem, but it seems like microcontrollers have advanced by leaps and bounds in the last 20 years, in almost all regards, higher clock speed, more peripherals, easier debugging, 32-bit cores, etc...  It is still common to see RAM in the 10's of KB (16/32&nbsp;KB).  It doesn't seem like it could be an issue of cost or size directly. Is it an issue of complexity with the RAM controller above some threshold?  Or is it just that it isn't generally required?  Looking over a parts matrix at a popular Internet supplier, I see one  with 256&nbsp;KB for less than US$8, and then for a few dollars more you can find a few more that are ROMless, but it seems pretty sparse...  I don't exactly have a need for a microcontroller with a MB of volatile storage, but it seems like somebody might... Max Planck, arguably the leading theoretical Physicist of his day, apparently used of experimental data to formulate his equation for , which was a major step in the birth of quantum mechanics. For this seminal event of the 20th century, I would expect a detailed explanation of how Planck arrived at his conclusion that energy MUST be quantized. I've even read his Nobel lecture but was non the wiser.  Can some kind person please explain it, or give me even just a hint? Searching for Google contacts not in Groups Possible Duplicate:          In Google Contacts, I've had Groups set up which look like this: All Contacts.. Family.. School.. Work.. etc.  Each contact I have is assigned to All Contacts. In addition, it is assigned to at least one more Group.  Sometimes when I add contacts, I forgot to bucket them in the respective groups, so I was wondering is there anyway I could do a search for contact that belongs toAll Contact-group, but does not belong to any other group ? The origin of spin is some what a puzzle to me, everything spin from galaxies to planets to weather to electrons.  Where has all the angular momentum come from? Why is it so natural?  I was also thinking do photons spin? we always think of the wave as a standard 2d sin wave but could this rotate in 3d? What implications would this have?   And what about spacetime how does all the spinning effect?  This has always been avoided in all lectures and classes I ever went to. Comprehensive Rules for Game of Thrones Lines of Succession I'm three quarters through the third book, "Storm of Swords" right now (so please, no spoilers from too late in the book or any subsequent books).  I just read a part where Tyrion is discussing with Prince Oberyn and they mention the difference between Dornish law and Westerosi law in Line of Succession (ie women can rule under Dornish law).  I'm a little confused trying to puzzle out what the exact LOS rules are.  At first I though it was: at the moment a king/lord dies, to find who holds the title next, you do a depth-first search down the family tree starting with the oldest sibling (ignoring anyone who isn't true-born or has given up their claim ie as Night's Watch or Kingsguard etc.).  Then, for Dornish law you take the first living person and for Westerosi law the first living male person found in this way (so succession can pass through a woman in both cases, but only Dornish law actually allows them to claim the title). If there are no valid living heirs, then you work backwards along the paternal line until you find an ancestor who has living heirs and start from them.  But there were various references to if Sansa's brothers were all dead, then her child would claim Winterfell.  It seems to me that that's only true if somebody else doesn't get it first.  In other words, if Sansa's brothers are killed before she has a child (even if she's already married), doesn't that mean Winterfell would pass to the nearest cousin along her father's line (whomever that may be)?  And then because that cousin has already held Winterfell, when they die the next in the line of succession starts from them so Sansa's children's family would not have claim to Winterfell again unless that cousin has no valid heirs.  What am I missing here? Is there some exception?  Are there no valid cousins? Why are there two ticker symbols for Google — GOOGL and GOOG?  They seem to be mostly identical, but their market values are different: currently, 551.64 for  and 548.79 for . This is a homework problem and I'm having trouble just getting a basic understanding.  I understand that $S_6$ is a symmetric group of degree $6$.  I'm not sure how to start looking for elements. Distribution of Dark Matter around galaxies It is well-known that measurements of the velocity profile in galaxies are not compatible with Newtonian laws. A way to circumvent the problem is to assume that galaxies are surrounded by a spherical halo of Dark Matter. The density of mass of this Dark Matter can then be computed from the velocity profile with Newton's laws.   My question is the following: the formation of a galaxy involves essentially only the gravitational interaction. According to Newton (and General Relativity too), the trajectory of a particle does not depend on its mass. As a consequence, I do not understand how usual matter and Dark Matter could have followed different trajectories leading to such different mass distributions nowadays. Can somebody explain this (apparent) paradox ? Is the space $\mathbb{N}$ is a baire spaces ? yes/No Is  the  space $\mathbb{N}$  is a  baire  spaces ?  My attempts :   No ,  It  will not form a  baires  spaces ,  let $C_n= \mathbb{N}\setminus\{n\}$. This is open (since $\{n\}$ is closed in $\mathbb{R}$, hence in the induced topology of $\mathbb{N}$) and dense, since every open ball with center in $\mathbb{n}$ intersects ${C_n}$. But  $$\bigcap_{n\in\mathbb{N}} {C}_n = \emptyset$$  So $\mathbb{N}$ is not a baires  spaces because for  Baire Space the intersection of a countable family of open dense sets must be dense.   Is  Its correct or not ? Short circuit or disconnect to bypass a compressor I have an Altec Lansing ATP3 2.1 audio system PCB which I reverse-engineered, and I would like to bypass the JFET compressor that's on it. Its active components are a JFET and four op-amps. I will connect the input to the output so it gets forwarded to the next stage.  My question is: should I disconnect the input and output from the compressor (in that case should I remove power supply as well, which would be very annoying), or can I leave it connected but short-circuited?  The block I want to short-circuit is the pink one on the left.    I realize the image is very small. The sound comes in on the right, in the green box. In the middle yellow box there's some trebble/volume/bass control. The small green box on its left merges the left and right channels to forward it to the subwoofer section, which is the complete left half of this diagram (except the red box on the left, which is just power). Signal then goes through a low-pass, a small equalizer and a compressor (the big purple box). It finally gets amplified in the brown power amp. How can I draw a tangent ending smoothly in a circle? I'm trying to draw a tanget on a circle, but I'm not happy with the result I get from the tangent option.    particularly, I'd like to have the lines ending smoothly in the circle. The problem is shown enlarged here:      Here is the code for this mininmal example  \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{calc}  \begin{document}   \begin{tikzpicture}[thick]     \node[draw,circle,xshift=2.2cm] (big) [minimum size=25mm] {};     \node[draw,circle] (small) [minimum size=2mm] {};     \draw (small.south) -- (tangent cs:node=big,point={(small.south)});     \draw (small.north) -- (tangent cs:node=big,point={(small.north)},solution=2);    \end{tikzpicture} \end{document}   I'd greatly appreciate any advice allowing me to do this!
