Great Theorem - Help name the Sci-fi book read long ago I'm trying to find a book I read long back. This book may have won a Hugo/Nebula (Trust me I've googled to death this one!).  Don't remember much of the story (that's why I want to re-read it). What I remember is that some of the powers in the book are called "Gods". And they have brains the size of the planets (or planets being their brains).  The protagonist in the climax, solves a theorem (The Great Theorem, perhaps) by remembering one of the obscure theorems (Jacuzi (?)) and incorporating it. This [Great] theorem helps spaceships helps find the shortest route from point A to B. He surprises the antagonist by reaching the vantage point quickly with the help of his new knowledge, and blasts his enemy's spaceship.  The ending of the book - as I remember it is - that the protagonist wants to become a God himself.  Please let me know the title &amp; author of this book if you've read it.  PS #1:  BTW, It's not Asimov's The Gods Themselves :) PS #2:  It's published at the least before 1998 Is there always an equivalent metric which is not complete? How do I beat Uprising on Legendary difficulty? The achievement "Distinguished Service" requires that you beat Uprising on the regular gamemode on Legendary difficulty.  This means we can't pick our usual huge DPS heroes like Bastion and Orisa, and are stuck with Torbjorn, Reinhardt, Mercy, and Tracer.  The phases are as follows:   Hack all 3 terminals Defend the Payload until it's ready Escort the Payload until the gate Destroy all 4 Orisas.   So I ask this after having failed Uprising on Legendary dozens of times.   How do I beat Uprising on all 4 phases?   Specifically asking for the latter 3 phases.    Defending the payload is hard when it gets to the Bastions that drop in because Reinhardt's shield gets melted very quickly and Torbjorn has little to no DPS.  Tracer must be relied on but it seems there is no way to stop the perfect aim of Bastion as strafing around does nothing.  If and when we actually do manage to defend it, we're stuck on escorting, which is even harder thanks to the tank mode Bastions.  And finally, even if we do make it to the final fight, which has only happened once, the fight is so tough that even if we slowly inch ourselves closer to the end we run out of time.  The previous question I asked was different because Uprising (All Heroes) allows you to pick any 4 heroes to form your squad, but the original gamemode will not let you pick. Also, the achievement requires you to play the original mode -- Uprising (All Heroes) on Legendary does not reward players with the achievement. I am going to Santa Monica for 4 weeks to polish my English in July and would like to volunteer at the Planetary Society located in Pasadena.  I am a Swiss citizen and have a biometric passport. However, I don't have any special visa, as there is no visa needed for the school I am attending and using the Visa Waiver Program, I am allowed to stay up to 90 days in the US.  Am I allowed to do volunteer work during my stay? I'm in the following situation: In 3 months, I'll finish my PhD in theoretical physics, and I'm certain that I want to pursue an academic career. However, I'm just as certain that my PhD research is a dead end. (My advisor doesn't think so, but I disagree with him.) Thus, I seek to change the direction of my research, but I need a few months to obtain the necessary skills. Anyway, I missed the main application period for post-doc positions (in the US).  Given the following options (feel free to expand this list), which do you think provides the best perspective of leading me to a interesting post-doc position?   Finish my PhD. Get any post-doc position. Do the work I'm required to do there. Work hard in my spare time to teach myself the stuff I want to. After 1-2 years, find a post-doc position I'm really interested in. Finish my PhD. Get a well-paying job in the software industry. Do the work I'm required to do there. Work hard in my spare time to teach myself the stuff I want to. Work harder to keep publishing papers. After one year, find a post-doc position I'm really interested in. Abort my current work. Find a new subject and a new PhD advisor. Live on unemployment money as long as possible. Work hard in my spare time to teach myself the stuff I want to. Work harder to keep publishing papers. After one year, find a post-doc position I'm really interested in.   Pros:   Get the PhD title sooner. Stay in the scientific community. Get the PhD title sooner. Earn lots of money (6 figure). In a 9-to-5 job, have more spare time for private research than on a post-doc position, where work is never finished. Go to a foreign country. It's what I should've done 2 years ago. I'll have the education I want when I finish my PhD, not later (but be older anyway). No immediate advantages over the other options.   Cons:   If a logical continuation of my PhD work, I'll suffer from demotivation. My next advisor will not want me to work on other topics that I'm not paid for. Might have to stay for 2 years. I'll move out of the scientific community for some time. I know it's hard to get back in. I'll be even older when I finally get my PhD. Not sure if I would find another advisor. Open fight with my current advisor. I don't want to live on unemployment money for long.   A particular question concerning the options above: Does being out of academia for a year kill your prospects of obtaining a postdoc position later?  I do have some collaborators who will help me to keep publishing, provided that I put enough work into my research. Also, I'm willing to familiarize myself with other topics on my own (a prerequisite for an academic career anyway).  The next application period will be from October to December 2013, which isn't far away. I'm sure I'll have most of the skills I want by then (and a paper published proving that), but still would have to work until summer 2014 wherever I am applying now.  Please give me honest answers, even if they hurt. I'll provide more information as soon as possible, if anyone has questions. Space between 2 paths in Illustrator I have a Toshiba Satellite laptop. My charger has stopped working.  I have access to a Lenovo charger. Can I use this charger on my laptop? If apostrophe + s is the acceptable way of denoting a genitive in English, is it possible that possessive pronouns, such as hers, ours and yours, started life as possessive adjectives with apostrophe + s?  E.g. her's, our's, your's, their's? Perhaps, even his' ? Its and my obviously stick out from this tempting pattern.  Is there any evidence that this might be the case, or is the 's completely unrelated? Looking for sci-fi short story anthology with a particular story of an Earth/Mars war children inheriting the surface I read this in the early to mid 80's.  It was a textbook sized hardcover anthology with color illustrations throughout.  Each story had a few images, some were full page illustrations.  The particular story I remember the most involved Earth survivors living underground.  Robots controlled the war from the surface.  A teenage girl and boy decided to sneak away to the surface as no one had been up there in a long time.  The kids discover greenery and a healthy environment, with rusted robot guardians.  The robots had been keeping the humans fooled that the war was still going on, and had kept them under the surface.  Mars had been wiped out from nearly the first volleys of missiles.    The robots judge the teenagers as worthy and let them remain on the surface.  The kids had silver jumpsuits that dissolved when they got wet.  The robot illustrations were blocky, almost weathered stone-like statues.  They had nearly spherical feet and square simple heads.  The faces had eyes and simple mouths.  -edit- The robots were similar in shape to the one in this picture, but smoother, and no arms.  The illustrations with them had the robots being several stories tall.  I kind of remember that the kids emerged from the belly of one or something like that. Give an example about limits: $\lim\limits_{x\to0}f(x^{2})$ exists but $\lim\limits_{x\to0}f(x)$ does not. I have found that the question I want to ask someone had asked, here is the website:    Here is my question: Why $\dim(\hom(V,W))=\dim V * \dim W $?    Thanks for explanation~! Can helium disappear from Earth? In my Java application, I want to run a batch file that calls "scons -Q implicit-deps-changed build\file_load_type export\file_load_type"  It seems that I can't even get my batch file to execute. I'm out of ideas.   This is what I have in Java:  Runtime.    getRuntime().    exec("build.bat", null, new File("."));   Previously, I had a Python Sconscript file that I wanted to run but since that didn't work I decided I would call the script via a batch file but that method has not been successful as of yet. I know how to define a package or a class, but how do I make it available (to myself) at all times?  Say I have the package file commonstuff.sty (or myprettyclass.cls), that I want to be able to include in any .tex file I create on my computer. Where do I put it? Do I need to run some installer on it, or is it enough to keep it in a certain folder?  Note: I know I can just place it in the same folder as the .tex file, but that's not what I'm after here. I'm looking for a way to "install" the package centrally on my computer. As we know, any proposition can translate to Godel numbers, such as  $$( \exists x)\space (x=sy)$$Its Godel numbers is $2^8 × 3 ^4 × 5^ {13} × 7^ 9 × 11^8 × 13^{13} × 17^ 5 × 19^ 7 × 23^ {17} × 29^ 9=a \space big \space number $  We also could get the character sequence "$( \exists x)\space (x=sy)$" through prime factorization of this big number.  Such as$$243,000,000=2^6×3^5×5^6 $$ $$6\space\space\space\space\space 5\space\space\space\space\space 6 $$ $$\downarrow\space\space\downarrow\space\space\downarrow$$ $$0\space\space\space=\space\space\space 0 $$ So $243000000$ is the Godel numbers of "$0=0$"   There are four axioms in Godel's PM system, here are two of them: $$(p\lor p)\subset p$$ $$p\subset (p\lor q)$$ through these two axioms, we can prove "$(p\lor p)\subset(p\lor q)$" is a true theorem.   And these two axioms and a theorem all have a corresponding Godel numbers, can we prove this theorem is true through Godel numbers? If it works, how?
