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...

Homework Statement I have a basic understanding of electrostatics. I know that when I rub a balloon with wool, both the wool and the balloon will become charged. I know that if I bring my charged balloon near neutral paper, the paper will be attracted because of charge polarization. I thought...

Need a Topic! I’m in the 3rd year of Electrical & Electronics Engg. and well it’s high time I started work on a Technical paper. Primarily I’m interested in Power Electronics and love doing work on Electric Circuit Theory. Also love working in anything related to Mechanics. Microcontrollers...

I've attached the paper in Q, please see Q 8. Not sure what to do. Also confused about the fact it says 'calculate', when it depends on p and delta, so I don't see why I should get a numerical value. I don't know how to get an expression for N here, apart from a really messy and horrible...

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...

Guys, I need your help. I am now doing a research paper for my English class. It is about Micro-transactions. I am trying to prove that Micro-transaction will help solve or lessen piracy. I need your opinions about micro-transaction. What are the benefits you get from it? What is/are...

After watching the video below, I came up with the idea of using a piece of paper as a keyboard much like Mistry did for a mouse. I am only in high school, but I'm sure you can measure position via sine waves which relates to the sin trig function (the reason I posted here; if wrong thread, mods...

Hi Everybody :) Recently I have been thinking on the concept of reusing paper instead of recycling it by using a special kind of photo-chromic ink, as chemistry is not my profession ia m writing here just to have your opinions about viability of this concept: what is the concept about...

They can only be carbon-neutral or better if sustainably harvested, of course. And only if the lumbar companies plant trees after they fall them. But if these assumptions hold (which I believe they do in many regions of the U.S.), then cutting down trees helps sequester carbon. Trees grow...

what title say, how?

Hello everyone. I have been looking for a book or any article where I can get a good description about classical theory of energy transfer from electromagnetic field to a particle. I am particularly interested in how much work is done by the field when it interacts with the partciel (for...

Penrose and Gurzadyan are not giving up without a fight. They posted a second paper today, answering their critics: http://arxiv.org/abs/1012.1486 More on the low variance circles in CMB sky V.G.Gurzadyan, R.Penrose 2 pages (Submitted on 7 Dec 2010) "Two groups [3,4] have confirmed the...

Hi I want, once and for all, to abolish pencil and paper in my studies. At least in what concern mathematics. I mean, I want to do my "pencil and paper calculations" electronically. Note that I'm not talking about using any computer algebra system. The problem is that I haven't found...

Homework Statement I have an extra credit assignment. I can write on any topic involving quantum mechanics (graduate level class). I needs to be a technical paper. I have tried to obtain more details about format from the professor but she does not help much. I have never written a physics...

Thank you Marcus for spotting this paper. Fotini Markopoulou takes a non reductionist view of Planckian physics in this latest writing, where more fundamental physics doesn't have to be more or less simpler than the physics emerging from it. This line of thinking remind me P.W. Anderson's...

LINES + GRAPHINGZ OH EMG EE!11oen1!1one Seriously though, does anyone use Doane paper? It seems excellent and I've heard great things. I am going to order some, and see how it goes. Unless there is a reason not to I haven't discovered, so, does anybody use this paper? Alternatively, does...

This is a bit of a silly question, but one I'm curious about ... It all started when I made a status update on facebook proclaiming that if you could fold a piece of A4 paper in half 44 times it would reach the moon. One of the commenters made an interesting point by saying: I...

Didn't really know what board to put this post on, but anyway... After finishing a 10 day lab project, I'm expected to produce a 2 (possibly 3) page conference paper about it. Having never written a conference paper before I'm not too sure what to include and what not to... I have...
