{{helpme}} How and where would I get templates to put on my account pages?

There are many forms of templates. You can explore a vast number of them at Wikipedia:Template messages. However, based on the context of your question, I suspect you are looking for userboxes. Please see Wikipedia:Userboxes.--Fuhghettaboutit (talk) 04:20, 3 February 2008 (UTC)

[edit] Physics major and careers

I chose to answer on your talk page because my answer is likely to be rather long and not exactly pertinent to the question you asked on the reference desk. I myself am a sophomore at Duke University majoring in biophysics with plans to go onto graduate school, so maybe I can give you a heads up to some of the important questions to keep in mind whether you chose to be a physics major/grad student or not. Anyway, I scoped out your user boxes and I am going to assume that the information is current which makes you a 9th grader. It's good to start thinking about these sorts of things early, but before you pick out your ideal job you want to apply for in 11+ years, it is probably more important to figure out what kind of undergraduate college is right for you. Two things to think about...

  • What are your academic interests? Are you mostly interested in sciences only or are your interests more general? If you are primarily interested in the sciences, then you will want to make sure you consider tech and engineering schools. If your interests are more ranged then consider a liberal arts school which will allow you to take a variety of science and non-science classes. (Duke has both a liberal arts and an engineering program) You want to make sure that the college you go to can span your interests.
  • How dead set are you on physics? Have you taken a physics class yet? Did you decide this recently or has physics been your "gut instinct" for a while? Obviously if you think you could change your mind that will affect college choice. I thought I read somewhere that most people going to college aren't sure of what they are going to major in, so you don't have to have everything completely planned out yet.

I am going to have to cut myself short to keep myself from rambling, but if you have more questions, you can either ask me or post to the ref desk. Sifaka talk 21:49, 19 April 2008 (UTC)

[edit] Question to keep from Math refdesk

What is the name of this equation and what is it's significance? What does it mean? \langle\Omega|\mathcal{T}\{\hat{\phi}(x_1)\cdots \hat{\phi}(x_n)\}|\Omega\rangle=\frac{\int \mathcal{D}\phi \phi(x_1)\cdots \phi(x_n) e^{i\int d^4x \left({1\over 2}\partial^\mu \phi \partial_\mu \phi -{m^2 \over 2}\phi^2-{\lambda\over 4!}\phi^4\right)}}{\int \mathcal{D}\phi e^{i\int d^4x \left({1\over 2}\partial^\mu \phi \partial_\mu \phi -{m^2 \over 2}\phi^2-{\lambda\over 4!}\phi^4\right)}} Ζρς ι'β' ¡hábleme! 05:15, 5 June 2008 (UTC)

I think it means, "I really wanted to show off when I was writing this equation". Or maybe, "Nah, nah, my brain is bigger than yours!" « Aaron Rotenberg « Talk « 06:23, 5 June 2008 (UTC)
Holy shit, is that an integral inside an exponent inside an integral???? Someguy1221 (talk) 06:44, 5 June 2008 (UTC)

I think this actually belongs in the physics desk. This looks more like something a physicist would write. More precisely, it looks like statistical physics / quantum statistical physics / conformal field theory. I would not assume that this is necessarily show off. Oded (talk) 09:49, 5 June 2008 (UTC)

Yeah, looks like physics to me. I think some context would be useful - where did you find the equation? --Tango (talk) 14:32, 5 June 2008 (UTC)
I found it on Uncyclopedia and YouTube; however, it has been verified as a legitimate equation on the Science refdesk. Note: I didn't cross-post this so you don't have to tell me not to. I don't know who did though. Wisdom 89 did. Ζρς ι'β' ¡hábleme! 19:23, 5 June 2008 (UTC)

I think I've seen this before in a book about prime numbers. I think it's something to do with Srinivasa Ramanujan; although I'm most probably wrong... Jonny23415552 (talk) 19:52, 5 June 2008 (UTC)

Guessing: The left hand side is a Dirac bracket of quantum mechanics. Ω is a state vector and T is an operator. The right hand side includes covariant tensor derivations of a potential Φ. The denominator is a normalization constant that makes the fraction a probability. The integration inside the exponent is over a four-dimensional volume. The m is a mass and the λ is the cosmological constant. The value of this integral is a phase. The Planck constant does not enter explicitely into the equation, so the units chosen make the Planck constant equal to unity. So this may be an equation attempting to express quantum gravity. I am merely guessing. Bo Jacoby (talk) 21:53, 5 June 2008 (UTC).


'OPERATOR'

What does this operator mean (the "\bigoplus" one)? V=\bigoplus_{n=0}^\infty V_n --Ζρς ι'β' ¡hábleme! 19:23, 5 June 2008 (UTC)

Direct sum. --Tango (talk) 19:49, 5 June 2008 (UTC)
(ec) The "\bigoplus" is just a big version of "\oplus"; it can be used to depict iterated application of the operator, like the sigma is used for summation. Your formula \bigoplus_{n=0}^\infty V_n is thus equivalent to V_0 \oplus V_1 \oplus V_2 \oplus \cdots, as you probably know.
The interpretation of \oplus itself depends on context; I've seen it used for the XOR operation and for the intersection of constraints in constraint satisfaction literature (the latter is thus identical to the intersection operator \cap). Oliphaunt (talk) 19:56, 5 June 2008 (UTC)
With the Vs, though, it's extremely likely to be the direct sum of vector spaces. Algebraist 23:03, 5 June 2008 (UTC)
