Here in the 3d world, we have 2d paper where we can draw 2d representations of 3d objects. How would a 2d being draw a representation of a 2d object on a line? Is that even possible?

So i need to write a IB Extended Essay in physics. I have a research question already but am having trouble when it comes to writing it, I’ve looked at some example papers but all their layouts seem to be unintuitive. The essay should be around 3,800 words, the lab reports we usually write are...

Hi, i wanted to make a laser cutting device, not the big one but a small device just to cut a few mm thick paper. I just learned from a site(www.ehow.com/m/how_6692865_make-homemade-cutting-laser.html) that you can actually convert a laser pointer to a laser cutting device by rotating the...

What is a good review paper on modern medical physics? Thanks

Does anyone have an English translation of Einstein's 1906 paper "The Principle of Conservation of Motion of the Center of Gravity and the Inertia of Energy"? A copy would be greatly appreciated.

Hi everybody! I`m Russian scientist and work in area of biochemistry. The main tack of mine now is publishing a paper in a journal, it is desirable, with Impact factor. May be, you know some journals, non very captious, with friendly reviewers, where this is not so difficult to publish...

Homework Statement Two students threw a paper plane towards the bin, hitting a desk at time t=10. The trajectory can be modeled as follows: x=t-2sin(t), y=4-3cos(t) Then there were a few simple questions before: The students are curious about what would have happened to the paper...

Hi, Would anyone like to critique my physics paper "The Greenhouse Effect"... it's only in draft stage but would definitely like some feedback positive or negative... not just on the material but on the overall structure as this is the first science paper I have done at university; I don't...

I simply need to shoot a paper plane very far, the furthest distance. I cannot interfere with it during flight. I plan to have copper wires up a standing pole, from the pole, an extension (used as a ramp for the plane to gain acceleration), will stick out less than 90 deg/ Perpendicular). On...

Homework Statement I have attached the question Homework Equations The Attempt at a Solution so the first thing I did was find the frequency = 120 Hz The next thing I did was find the circumference = 0.2796 m (from pi*d) Now I know that the answer is no. magnets per disk *...

Question about the "reality of the quantum state" paper by Pusey, Barrettm and Rudolp In the paper I mentioned in the title (on arXiv and supposedly subsequently published in a journal), the authors claim to show that "if a quantum state merely represents information about a system, then...

I have to compare measurements in a normal distribution with a theoretical gauss curve on "probability paper" (the y-axis has percent). Does anyone know any online guide/ information? thanks, have wasted the last three hours on this

http://edition.cnn.com/2012/05/10/showbiz/texas-stripper-writer-fired/ If the paper has something against people working as strippers, it seems to me kind of stupid to fire them from the paper, because her main work option now is to go back to stripping. This kind of sends a message to anyone...

Hi everyone, I have a very general question about how to read a review book or paper? My tutor want to me read the book of deGennes and Tinkhan to start learning superconductor. Although I can unserstand the main features and even calculation,but i still can't "understand" BCS theory, I don't...

At our recycled paper mill we are planning to install a spray starch system to help with ply-bond . http://www.freeimagehosting.net/t/1h2ie.jpg The basic idea is to feed 14 % starch slurry and recycled water into a centrifugal pump. The diluted slurry then runs through rubber hosing, valves...

Dear everyone, I know this is not exactly on topic here, but I thought it was even more off topic in the other sub-forums, so please forgive me for posting it here. I'm looking for some advice and maybe some help. Recently I have finished my work on a paper about the emergence of the Born...

In medicine and biology they have Medline which is a complete database of research papers---kind of a complete search engine of research papers in medicine and biology---which has free access to public. Is there anything comparable to this in physics---...

I'm assignated to do a lab report which consist of a numerical molecular simulation of water with a very particular water model. My program is already running but my professor didn't talk a lot about the model in particular. At this point -and I think it's totally fair-, we're expected to...

Hey guys, I am a little confused with the concept of Capillary actions with specific regards to paper towels. I understand the mechanics behind a single capillary tube and the height that water reaches in relation to surface tension. However, my professor claims that paper towels absorb as...

I know that right now an A4 page sells for 0.8 cents at Walgreens. So presumably the thing is dirt cheap at the factory gates. For toilet paper I don't have any handy store prices to quote, but I do have a nagging suspicion of being overcharged. So, generally speaking, what is the economic...

i mean how to find conferences.?

I'm currently in high school Physics B AP, and we have been given a research project in which we can pick our own topic. The topic I have chosen to research is the Higgs boson, commonly known as the "god particle". We have to write a research paper (5-7 pages only), create a physical model of...

SR, Do you calculate closing speed to determine light arrival time? Please evaluate the paragraphs below... what I'm most concerned about the very last statement. Do I integrate the "motion" of the distant object to determine the arrival time of light or is that already in the calculation...

By Wheeler (and DeWitt), it's called "Superspace and the nature of quantum geometrodynamics", 1968. I googled it, but all I found were papers/books that had this paper as a reference...I can't find the paper itself, anyone have some good sources for where these things are? Surely it's online...

Hi everyone, my first post here. I have worked out some of the problems facing physics in general and quantum mechanics more specifically in my head and am planning to submit a paper to a scientific journal to put out the ideas and have them reviewed and hopefully accepted as new clues to...

I've noticed lately a lot of my professors use yellow paper pads to write out their lecture notes instead of white ones. I don't know if it's a generational thing, but I never liked yellow paper and always thought it felt cheap and not nice to write on, so I'm wondering what the appeal of it...

How do you publish a scientific paper? How do you know that your idea has not already been published somewhere? How would you go about making sure your idea is new? What happens if you wrote a paper in a field that someone already researched on without knowing? Who do you speak with to start a...

As part of an assignment, I have been asked to construct a tower that is completely made of paper and sticky tape. This tower must be built with 4 specifications: 1. Must be built of nothing but paper and tape no cutting devices, glue, ect ect. 2. Must be built within 5 minutes. 3. Must be...

Why does a wet piece of paper let through more light than a dry one?

I am writing a paper for my New Frontiers of Astronomy class on dark flow. Does anybody no any links to a great deal of info on dark flow. I've printed up the actually science paper on it. Any links relating to the causes of it or disproving it by other physicists will help.

I hope that a short discussion of the history of theoretical development is not too much off-topic here; this is a continuation of a discussion started under another, related topic: https://www.physicsforums.com/showthread.php?t=574624&page=2 The paper under discussion: Albert Einstein, "Über...
