Posted by KawaPosted by al2fenrirYou're forgiven. I don't get them either. Maybe Blackhole does. Maybe. I daresay the math is some of the neatest stuff you'll ever find in terms of applications of math, it's the nitty-gritty real stuff like the problems with quantum teleportation and what we can do with it really. It's really lamentable that most physicists and scientists aren't on the cutting edge like guys like Witten and you only have a handful of mathematical physicists and geometers who really understand. There's one good website I go to by a certain mathematical physicist that has a sliding scale of difficulty from layperson to unbounded difficulty, but most of the hard stuff is delegated to papers and books (or other websites). A lot of it is just pretty pictures which is good, and enlightening diagrams--which are also good. Even if you don't know any math I'd encourage anyone to take a look at it, since you'll find a lot of interesting sciency stuff in one place without the erroneous popsci sort of stuff which tries to sell you unbelievable stories. But yeah I haven't really gotten to reading a lot of the physics stuff lately since I've been busy with math, but quantum field theory or more generally gauge theories are something I want to learn about, along with gravitation which I have a general understanding of. Not to speak for someone else, but I think blacky is also looking to get into this sort of stuff. If you just want to know how teleportation works it might be too much effort and it might be better to keep an eye on experimentalists' results, but from what I know there's been a lot of error when communicating information--far too much to do any of the futuristic trekkie sort of zap a pot of earl grey into existence stuff. |

Posted by al2fenrirPosted by SX I sort of thought that might happen so try this instead: Kindergarten Quantum Mechanics Start from section 3 on page 3 and keep on going, there's actually the same Alice and Bob problem sketched out. It uses pictographs! |

I'm going to be a mathemagician and I hope I'll get to meet awesome people like Lurie, do algebraic geometry/topology and differential geometry and topos theory.
I'll tell you what I'm not going to do, and that's laze around doing nothing, indulging in petty leisures, since consumption is only for lazy faggots. Posted by KP9000Posted by TreliorI'm a stocker at Big Lots and I feel it's a totally relevant decision to gain experience in this field prior to my employment at NASA's moon base. Work experience, maybe, but you're just kidding yourself if you think it's a great idea to not finish your bachelor's degree--preferably in a science field. I've told you before on IRC that you can get tedious coursework out of the way through accredited community colleges, and then transfer over to a four-year university once you're gotten the hang of calculus, physics, linear algebra, differential equations, etc. If you want to be a pilot, you have to log 1000 flight hours on a (fighter?) jet, so going the military route might be easier if you're considering that. Without a degree or relevant work experience, you are just wasting valuable time and making yourself less and less of a viable candidate. If you don't hurry up, you'll be lucky to be working with anything related with spacecraft unless you go on that Virgin space thingy. The older you get, the less likely they'll consider you, and if you wait too long you'll be too old by the time you finish school and get a job doing anything tangentially related to spacecraft. You can't just be fit or smart, you truly have to be at the top of your class and be in top physical condition, or you might as well give up, seeing as there are only 10~20 spots for astronauts and not that many more for NASA employees doing outer-space stuffs. You might be better off doing astrology or taking an interest in it, since you'll be hard-pressed to find internships for "astronaut practice" although you can join programs where students stimulate being on Mars or the moon or whereever in the middle of the desert--maybe living in the middle of a racist shithole paid off! Posted by al2fenrir Seeing as you're already a nurse, you must have completed some math coursework, and the only thing holding back people from understanding things like physics is a pathetically meagre understanding of math--something which basically anyone can learn, just like I suggested to KP, you might want to start with calculus and linear algebra, and move on to things like differential equations or differential geometry if you want to understand nonlinear phenomena. It's not a matter of talent or anything like that, but just solving lots of problems and thinking seriously about the coursework. Since both of you might be interested in math/sciencey-stuff, I thought I might suggest this intro text modeled after the course taught to Russian schoolchildren which gives the reader a good feel for mathematics, without having to know a ton beforehand. Requisites are minimal, just knowing how to work with basic stuff like the quadratic equation, and not slacking off/giving up. If anyone wants to start up a thread to work through it together, I'd love to help anyone out. Of course if you want to continue living vicariously through the efforts of others it's always a plus in science where cheerleading results you understand nothing about is clearly the best option. This 80 page typset lecture notes will put you in shape to attack mathematical texts at will, and is very careful to define and motivate everything very carefully (it's for schoolchildren after all!). Right now you probably have the mathematical sophistication of a Middle Ages commoner, perhaps less, since at least they thoroughly went through Euclid's Elements. If anyone is interested, there are several good books on Calculus at the beginner level, several excellent books on linear algebra which is essential, and one good book for differential equations (VI Arnold's). Most modern treatments (younger than a few centuries old) of any physical theories will likely involve differential equations/geometry, for example everything from mechanics, electrodynamics, gauge theory, elasticity, gravitation, deformation theory, image processing, modern 3D game design (computational differential geometry involving meshes and stuff), fluid dynamics, anything involving MRIs, game mechanics...the list goes on, and that's just a few things that those two subjects (which are closely related) shed light on. Basically, math is super useful throughout the sciences, requires no expensive experiments or even a certain level of technology, yet has tremendous applicability with very little effort. I've found books like Fifty Challenging Problems in Probability with Solutions, a slim book with lots of "puzzle" like problems which you can piece together the math you need, can often be attempted by said Dark Ages denizens along with much of the classical geometry pioneered by H.M. Coxeter. On second thoughts, if you want to go for calculus, the traditionally-taught calculus of real numbers is not as intuitive and easy -to-grasp as its complex counterpart, which has lots of very nice geometric examples. In a similar line of thought, the famous popularizer of mathematics, John Conway, has written a beautiful book filled with pictures and aimed at a solidly lay-audience, called The Symmetries of Things will prepare you for the group theory used in quantum mechanics (or if you want to cut the foreplay and try a physicist's classic, The Theory of Groups and Quantum Mechanics by Hermann Weyl is a great place to start, just like how his groundbreaking (yet very accessible) essays on spaces that led to the idea of differential geometry, The Concept of a Riemann Surface keeps things simple and at the level of surfaces which we are familiar with, like a sphere, a saddle-surface or a paraboloid. For example Calculus, by Michael Spivak is an excellent introduction, although if you like applied books, Calculus, Vol. 1: One-Variable Calculus with an Introduction to Linear Algebra (Second Edition) (Volume 1) by Tom M. Apostol along with Calculus, Vol. 2: Multi-Variable Calculus and Linear Algebra with Applications by Tom M. Apostol will teach you calculus, differential equations and linear algebra all in one fell swoop with lots of motivating examples to make sure you understand stuff. Otherwise, Gilbert Strang wrote the book which goes with the MIT OCW linear algebra course, which can be helpful if you like that sort of thing. When you think you understand calculus and linear algebra okay, then trying out VI Arnold's Ordinary Differential Equations gives a good taste for what dynamical systems/time-evolving systems/differential equations in the modern language of differential geometry. Most of these books can readily be found online, but it'd just take forever to upload all of them, so only the first one links to a PDF (perhaps the only one you should read for a starter). If anyone is serious about learning some maths, I can start up a thread, and since this board has wonderous LaTeX maths it can be done very easily (or use unicode i guess). |

If you're not in a hurry, dealmein tends to pull up good deals if you check in often or put up an alert, and http://forums.somethingawful.com/showthread.php?threadid=3241890&pagenumber=1&perpage=40#post369821733 offered a lot of good advice on squeezing the most out of your budget for a gaming computer--it's aimed at a 1000$ budget roughly but i just thought it might be helpful. |

Posted by NightKev considering there aren't too many competitors for the "cheap white chocolate with cookie bits" i would agree that they are pretty good. Hershey's and a bunch of other American chocolatiers decided that pig Americans would rather have cheap crap which isn't actually chocolate as opposed to raising their chocolate prices. Currently only their premium lines use actual chocolate. 
kp should save these for his desert training--since y'know candy bars are the prototypical energy bars. |

i sort of want to make a snippy remark about feline healthcare...
--however cancer sort of sucks, but it can be treated if you can afford radiation treatment and you probably want to get your cat on some dosage of painkillers if they're suffering. gamma knife treatment would be the least invasive i think but because of the lovely healthcare system in the US (and the state of research i guess) i'm not sure how widespread it would be. depending on where the tumor is, surgery may or may not be a terrible idea, since it opens up a slew of potential problems. depending on how far the cancer has progressed you might really want to just make sure your pet isn't suffering, it'll be a lot easier on you and your family that way. but yeah, if you can afford it, try to get a second (or even third) opinion and talk to them about stuff like radiation treatment or surgery (if it's cancer). i don't know much about kidney/liver failure so good luck with that. |
