I need find the thickness of a piece of paper based on the known linear speed of the paper coming off the roll and the change in diameter of the roll. I have the ability to see the linear speed. It is consistant but changes from roll to roll. I know the starting radius, instantaneous radius...

The problem has been highlighted in the attached picture, it's an old exam paper question and I've been trying to do it in preparation for a university exam. I am confident in modelling the structure (into both shear panels and edge members), and confident that I am able to identify both...

In a paper says that the limit when \alpha \to 0 with \sigma = \pm 1 of: \frac{1}{4 \alpha}(1 + \sigma \sqrt{1 - \frac{8}{l^2} \alpha } ) has a well defined limit only when \sigma = - 1 , ¿why??...I don't understand

The title just came to me: "Doubly special relative locality of Bilson-Thompson braids in an asymptotically safe, exceptionally simple E8-valued spin foam"

Some matured opinions are needed here. After a paper being rejected by Phys.Rev. journals (I already signed the copyright transfer) while the editor suggested 'may consider publication on other sections', can I still submit this paper to other non-APS journals? Thanks in advance.

Hey guys, I have a question about email addresses in a journal paper. It is natural for authors who are professors to leave their .edu email addresses because are rarely changed. But what about for an undergrad? I am graduating in 2 years and the school will delete my account after I...

Hello there forum! I would like to present a paper on quantum computers. Idk where to start from. I have high school level knowledge on quantum mechanics, semester on quantum physics and also the knowledge the feynman lecture vol 3 would give its readers.

I want to write a research paper on general relativity or mathematical physics. I am a college freshman (will become sophomore after this summer) belonging to an engineering major. In this summer break, I have managed to learn about tensors. Currently, I am following the Respected Professor...

Don't expect to learn a lot. They don't prove life is rare and they don't prove it isn't rare. Basically they argue that the evidence we have so far (life's quick appearance on the Earth not long after the surface temperature stabilized in the liquid water range) is not sufficient. They argue...

http://arxiv.org/abs/1103.2732 Abstract "Rough estimates are presented to show that the bump at 1.7 to 1.9 TeV seen in ATLAS-CONF-2010-088 could arise from about 10^{30} approximately degenerate Kaluza-Klein states of the d = 11 supergravity multiplet in the s channel, that could arise from...

I have a paper to write for linear algebra, and it has some mathematical notation, (sums, matrices, things like that). I was wondering what program I might use to type it so it looks pretty like a math test. Always wondered how they did that... I have access to an assortment of programs via the...

Of these twelve candidates, please choose the paper or papers which you think will contribute most significantly to future quantum gravity research. Since multiple choices are possible in the poll, you may select several papers. Abstract summaries follow in the next post. Holonomy...

Hi I use word 2007 for my extended essay in mathe but I can't use subscript in any fraction or function. What program do you gus use to write a paper?

Finkelstein's "unidirectional membrane" paper The "unidirectional membrane" interpretation of black-hole event horizons originated with this paper: Finkelstein, Phys. Rev. 110, 965–967 (1958), "Past-Future Asymmetry of the Gravitational Field of a Point Particle," downloadable from his web...

I just found a paper which was thinking along similar lines: http://casimirinstitute.net/coherence/Jensen.pdf Any comments on why FTL is not possible (after browsing the paper)?

Hey guys, I have to write a term paper over the summer long semester in a University Physics class. I'm completely overwhelmed with topics, and have no clue of what might be too general of a topic as this is my first physics class ever! Of course, we have to use library databases and...

http://arxiv.org/abs/1106.0971" . I regard Koide's relation for the charged lepton masses as the most neglected clue in particle physics. It's amazing that it isn't routinely discussed when people talk about BSM physics. The inherent difficulty of explaining it ought to be attracting...

Hey I'm curious what sort of strategies people use to efficiently read and understand physics papers. I've never really thought much about it until now, but I'm sure some ways are more effective than others. A simple google search yields some excellent tips, but most are geared towards less...

Has anyone read Max Born paper in 1926 where he proposed about the probability amplitude interpretation of the wave function? The original paper is in german. Did he mention that that "Psi is the probability amplitude for an electron in the state n to scatter into the direction m, it is, in a...

I'm about to sell a scientific paper (give authorship to another person), publishable to a moderately high impact factor journal. What would be the price range? :-)

In "Does the inertia of a body depend upon its energy content?," http://fourmilab.ch/etexts/einstein/E_mc2/www/ , Einstein says: My interpretation of this is that these energies contain both potential and kinetic terms. A potential energy U is only defined up to an additive constant. If, for...

Consider question 1 in this paper: http://www.maths.cam.ac.uk/postgrad/mathiii/pastpapers/2002/Paper65.pdf How do we "read off" the Feynman rules? I can see that the interaction terms give contributions \lambda_3 , \lambda_4 , \lambda_6 to the relevant 3,4 and 6 point vertices respectively...

Bousso and Susskind have a http://arxiv.org/abs/1105.3796" . I have two reasons for creating a thread about a paper which one might otherwise prefer to ignore, as it contains no new quantitative results or ideas for how to obtain them. The first reason is that the paper is bound to get...

Does anyone know what paper this news article is referring to? http://www.cbc.ca/news/technology/story/2011/05/19/science-dark-energy-einstein-blake.html I'm thinking it must be this one, http://arxiv.org/abs/1105.2862 but what the paper is saying and the way the article is...

Two years ago an intriguing paper of De Raedt's team concerning Bell's Theorem appeared in Europhysics Letters (http://arxiv.org/PS_cache/arxiv/pdf/0907/0907.0767v2.pdf). Now (officially next month), an elaboration on those ideas has been published: Hans De Raedt et al: "Extended...

Hi, I need to find an important, very recent paper in observational astronomy for a journal club presentation. It would help if it is short and easy to read :) . Could someone please suggest one to me? Thanks.

Hi all, I was looking at the buckling problem of a piece of paper with both ends clamped. When the two ends come closes they form a bulb-like shape and I was interested in deriving the shape numerically by solving NL ODE, which comes from energy methods (neglecting gravity). The ODE I got...

Homework Statement Okay, I am using my desk lamp right now to see better when I read, but it's making it more difficult to read because my texts are white sheeted based and it's reflection is making it impossible to read The Attempt at a Solution I don't have color filters, so I need...

Yesterday i was reading this new paper by Gerard 't Hooft. Its a complex paper, does anyone of you skimmed the paper yet ?. It certainly gives me fruit fot thoughts http://arxiv.org/abs/1104.4543 A class of elementary particle models without any adjustable real parameters Authors: Gerard 't...

Hello everyone! I am planning on writing a paper about the angle of repose of different granular materials (i.e.the cone that sand makes in an hourglass). My research will involve both experimental and theoretical work; I am going to collect data regarding the shape that different materials...

I've made an experiment similar to the one found here: http://classes.yale.edu/fractals/fracanddim/boxdim/PowerLaw/CrumpledPaper.html The result was: the mass of crumpled paper balls is proportional to D^n, being D their mean external diameter, and n ≈ 2,5. As n is not an integer, the...

I have read the Einstein June 30, 1905 paper "On the Electrodynamics of moving bodies" but I can't see how he did the following (the text I've quoted below is on page 6 in my .pdf version): " 1/2 [ T(0,0,0,t) + T(0,0,0,t + x'/(c-v) + x'(c+v)] = T[x',0,0,t + x'/(c-v)] Hence, if...

I only have a BSME with a very small amount of work experience (I graduated recently). I'm hoping that there is a decent scientific journal out there that would seriously look at my paper regardless of my credentials (or lack thereof), review it, and if they find it correct publish it. Also, I...

Hi, I initiated a discussion that got over heated before this simple question was answred so perhaps someone would like to comment on it. This began as a simple question regarding evolution and for me has become the focal point of a series of papers for a writing class. The discussion was...

Hi, My situation is just like someone who is running on a treadmill. He is running without getting anywhere! A couple of years ago I got my masters in physics (condensed matter) working on Density Functional Theory and simulation. My masters thesis ended with two papers which I submited one of...

I was glad to see this paper for several reasons. The volume operator in Loop Gravity is the locus of some interesting unresolved questions. The kind that requires and attracts creative mathematicians IMHO. This first paper from Gene Bianchi and Hal Haggard is just a 4-page letter I guess for...

I was reading a recent paper on arXiv.org on a novel simulation of MOND, and surprisingly they addressed the Bullet Cluster, which I guess is one of the more serious problems for MOND. What was even more surprising was that they said this posed a problem for Lamda-CDM models as well. Here is the...
