Homework Statement What interactions are at play in the following scenario, and what objects are involved in the interactions? A tiny bit of paper jumps from a tabletop toward an electrically charged comb. (Consider the bit after it has left the tabletop but before it reaches the comb.)...

Hi, I've just completed a paper looking at the possiblity of adding a new force between neutrinos. And I'm looking to get an Endorsement from a publishing physicist so i can uploaded it to arXiv. Its almost an fully orignal idea, although L.M. Slad, did derive a similar force, he didn't look...

I'm doing some research in which I'm using homology theory to solve a problem in computer science / engineering. Most of the work is on the CS part, but I know enough homology to get me around. I'm not really coming up with any new math per se. I'm not doing any hardcore proofs or anything. My...

For the first time the Immirzi has found its way into spinfoam. they also got a Lorentzian version. I think this is an important paper. both these guys are top QG researchers since like 1998 (when spinfoam and groupfieldtheory started to happen). this paper has to be major...

I have submitted a publication to physics Letters A in the field of supersymmetric quantum mechanics (SUSYQM) my teacher says this is a pretty big deal but would like to hear some others opinion. I will obviously mention this when I apply but is it THAT big of a deal? Should I make a big deal...

I've been trying to figure out this paper by W. Smilga: Spin foams, causal links, and geometry-induced interactions I don't have the knowledge and background to be able to determine whether his derivation of an estimate to the fine structure constant is interesting, or just a trick. I am...

I am trying to develop a mechanism for automatically scanning documents which involves picking up pages or sheets of paper. I need a method for determining whether an extra page has been picked up. I have considered using a beam of light that would pass through the page or pages and a sensor...

I can't seem to find double-sided 8 1/2 by 11 graph paper. I've tried looking at Office Depot but they only have one-sided ones. Does anyone know of the cheapest way to buy graph paper online? Does Staples sell any 2 sided-graphing paper? By the way, I'm talking about the boxed ones that are...

I don't know how they hope to get away with it, but I guess in string theory, anything and everything goes, especially with unrefereed "papers". These string theorists actually used a non-existent word "embiggens" from an episode of The Simpsons (BTW, the movie is hilarious!) in a "paper". I...

And I'd like to write it and do the work on my own. It's a project that would probably take me a few months. I'm wondering : What are the best places to check to make sure no one has done anything like it? Article searches I mean. I currently do not have access to the search engines that are...

JB starts This Week's Finds talking about the paper Garrett just presented at the Loops '07 conference http://math.ucr.edu/home/baez/week253.html what the Standard Model looks like and why steps toward unification (like Garrett's) look the way the do.

I found a very elegant proof of a very well known calculus level result. The result, I don't want to say which yet, has been definitely proven by other means. I researched all the proofs, in a few books and all google, never have I seen my result there. I asked a math professor about it, but...

Homework Statement I need to derive some equation that are on the paper "does the inertia of a body depend on it's energy content". http://www.fourmilab.ch/etexts/einstein/E_mc2/www/" I just don't know where to start and if someone can point me to the right direction, it will be so much...

Some body please explain quantum mechanics to me in ENGLISH please... I have a paper due on the stability of the quantum science but I don't even get it much less write a paper about it.. Thank you your help is aprreciated..

I'm extremely excited to embark on my physics project and it has all to do with ripping toilet paper rolls. As it is commonly known, when a full toilet paper roll is given a fast jerk, a sheet breaks off. However, as the roll is gradually used up, a faster jerk has to be applied or the...

Hi there, I wasn't really sure where to post this but here seemed the best place. I'm trying to find a journal article but having a bit of trouble and was wondering if anyone knew where I could find it. It's an article from The Journal of Experimental and Theoretical Physics USSR from 1947...

Very important new paper here. http://www.sciencemag.org/cgi/content/abstract/1138679v1 A little more descriptive: http://www.eurekalert.org/pub_releases/2007-05/teia-csh051107.php I think that this may fit a lot better to certain pet idea than to all the warming talk.

Hi all, I'm trying to understand someone's PhD thesis on the topic of variational surface evolution and its application in computer vision, and I'm having trouble working out how he evaluates some particular types of expressions involving the gradient. I think it'll be easier if I specify the...

In another thread, alec_tronn posted My basic reaction: Write a term paper for a calc 3 class?? My first and continued impression is that this requirement is just shovel work. It hinders rather than aids mathematical education. The time taken to write the paper is time not taken to learn...

Homework Statement A cone-shape drinking cup is made from a circular piece of paper of radius R by cutting out a sector and joining the edges CA and CB. Find the maximum capacityof such a cup. This is page#312 In James stewarts Calc book, 3rd edition by the way. Homework Equations...

Firstly, this is NOT a homework question although it may sound like it. My question pertains to http://youtube.com/watch?v=H5NwRfMJgOQ". My question is this: Could an Infrared Laser (there are varying power output lasers of 2W - 20mW) SPIN a paper of say 25 grams as seen in the vid on the tip...

Hi, I am designing an experiment for an individual project and it happens to involve aerodynamic. I wonder if someone can give me some idea of the drag coefficient of a square piece of flat paper (the normal 80grams photocopying paper) traveling through air against its face? (i.e. not...

I can't think of a way to "show that y=...". Do I compare to x values? Thx

Hi, I have a question tThe number 40 can be written as 2^m x n, where m and n are prime numbers I managed to guess that m = 3 and n = 5 by trials and error by using low prime numbers. Is this the proper/best way to work out the answer. If not can someone show me a proper way Thx

As some may have noticed, I have already mentioned that this paper doesn't really seem to be very clear but now I believe its mathematical basis is fundamentally flawed. I believe this a model used by the US Navy and cited many times in recent years so I'm assuming that I must be wrong on this...

Each quarter last year we put down our predictions about which recent papers will have most impact on future QG research: efforts to reach a fundamental empirical understanding of spacetime geometry and matter. For example, here's the forecast poll from third quarter 2006...

Hi all, As part of my differential equations class, I must choose a real-world event that can be modeled through a system of ordinary linear differential equations and write a five page paper on it. My professor was vague on the requirements but basically wants us to solve the equations...

Hi all, Whilst reading http://www.jhuapl.edu/techdigest/td1703/thomas.pdf I found one of the equations a little difficult to interpret. On page 3, there is a function defined as f. On the denominator there it appears that they have differentiated n(z''(Z')) as a function of z'' and then...

Can anyone reccomend a website for finding papers that have cited a particular paper? Google scholar can't even find the original, and Web of Science seems to only go back as far as 1970, and my paper was published in 1969.

Hey everyone, My question may show my modest experience regarding research papers legal procedures but i hope i will be excused. I have a reaseach paper i want to submit which i think it may be, or may be not, be of a significant importance. I have not finished it yet and thinking to...

Hello all! I have to write a review paper of several current articles for my Gas Dynamics course. My research is in Welding and Automation, so I have very little experience in the area of aerodynamics. However, I have recently read a book on Lockheed Skunk Works and think that I would like to...

By my judgment as a bystander watching from the sidelines, this is a fantastically high quality paper. Unless someone finds an error---which I don't think they will. It just came out. http://arxiv.org/abs/hep-th/0702016 Multi-Particle States in Deformed Special Relativity Sabine...

Please ,physics gurus analyse this paper and enlighten me about the validity of the paper. Is the person correct.I can't tell as i don't know the mathematics involved

technology assignment= PAPER TOWER you can only use one 8 1/2 by 11 sheet of paper and 3 feet of tape you can tape it to the floor has to stand for 5 minutes there are other threads about paper towers but none of them are specific enough to understand. i was going to do the eiffel...

I have been confronted with a strange and vague, but oddly interesting assignment of creating a research paper on an egg through the perspective of a physics. Does anyone have any ideas as to what i can research online or in a book over the PHYSICS of an egg? Thanks

Homework Statement A large, cylindrical roll of paper of initial radius R lies on a long, horizontal surface with the open end of the paper nailed to the surface. The roll is given a slight shove (initial velocity is negligible) and begins to unroll. Determine the speed of the center of mass...

This sounds like a stupid question... probably because it is. :-p But what program(s) is commonly accepted as the standard for writing and publishing papers? Obviously as an undergrad I just use Word (and Excel for the graphs) and get away with it, but when I compare the composition (not...

Hi, I was interested in writing a technical paper related to aerodynamics but the whole subject seems so vast. I'm finding it hard to zero in on a topic which would be technically interesting at the same time important with respect to the current practical requirements of planes. Would...

Hello, I have been working very hard over the past few weeks and have managed to confirm a theory I have been harboring for a long time (mainly, that Einstein was incorrect about light and that it is in fact not a constant but varies according to the region of space you are in). This has...

Topic of Paper -- What should it be? I'm looking for a topic to write a 5-6 page paper on. I'm talking Calc 1 now so the phyics class that I'm in doesn't really have any calculus in it. Any suggestions on what might make a good topic?
