Hi all, Please help! I am reading the paper "A note on contiguity and Hellinger distance" by J. Oosterhoff and W.R. van Zwet. I have tons of questions. The following is just one of them. Question 1: in their paper, when they prove the asymptotic normality they claim that according to an...

I have to write, with two friends, a simulation based physics paper at school. The problem is, that will I am quite familiar with the concepts of calculus and algebra, my friends aren't. So, we could find a good topic. The task is, to write a paper about a physical topic, with the use of a...

What is Quantum Entanglement, and what does it do? I attempted at learning via online articles.

I made two conductive plates out of aluminum foil wrapped around cardboard pieces i don't have a micrometer with me to measure to the thickness of my paper, so i just googled the average thickness of paper; also just googled the relative permittivity of paper..$$C=\epsilon_r \frac{A}{d}$$...

Hello. I have a question. I have two glasses - one is full, one is empty. And I will take a long paper towel to them - the first end to full glass and the second end to empty glass to same height. A paper towel is absorbent. Water from full glass rises to empty glass. It will stop when the...

Do I need to worry about the pore size, or can I just assume that any/all paper filter will remove the organic compound while letting the smaller HCl molecules through? The molecular weight of the organic compound is listed as "240"

Eric J. Lerner, long time Big Bang opponent, has published a paper that I don't really understand but claiming it indicates the universe is not expanding. Can anyone actually help to point out why or why not his observations should be given consideration? It was Published in Int. Journal of...

In AP Physics B, for our physics olympics, for one event, we are required to make a paper rocket that will be launched straight up in the air by an air compressor and pump. (60 psi) We have already assembled the paper rocket, with one cylinder of paper, a cone paper nose, and a load of tape to...

Why did Verlinde in his paper suggest that information is a central concept in the emergence of gravity? I mean why information and not something else?

I've got a term paper due in a couple of weeks and I need to find a historical physicist to write it about. The paper will highlight his/her's contributions to physics and will be a bit on the technical side (including equations, maybe some derivations and proofs). I was wondering if anyone had...

John likes to play baseball with his friends in the local playing fields. Last week John hit his best shot ever. The trajectory of the baseball after he hit it can be modeled by the quadratic equation y= -x2/40 + 31x/ 40 + 4/5 where y represents the height in metres of the baseball above the...

I have just finished writing a paper that deals with particle physics (primarily neutrinoless double beta decay), but also introduces certain innovations to important concepts in logic, linguistics, and mathematics. (For example, I propose that a new axiom be added to ZFC.) It is not a long...

Parody math paper - defining "properties" And no, I don't mean properties in the mathematical sense, but rather in the "everyday" sense. In a parody mathematics paper I'm writing, I'm trying to define the "properties" of an object as a stepping stone to defining similarity. If we let P(o) be...

You're not supposed to flush it down the toilet! :eek: https://twitter.com/wyshynski/status/430734034113536000/photo/1

2013 AUG Paper - Hawking "...gravitational collapse produces apparent horizons but no event horizons behind which information is lost." "The absence of event horizons mean that there are no black holes - in the sense of regimes from which light can't escape to ininity."

Hello, I have attached a paper about Planar Interferometer Arrays. Now I’m trying to understand this paper but something confuses me. I am very thankful if somebody can help me with it. 1: It seems to me that direction cosines and phase differences are 1:1 correspondent, that is, a phase...

Has anyone tried to use software not just for typing math to produce good-looking documents after solving problems/doing research with paper&pencil, but for actually doing research/problem solving with lots of maths directly in electronic form? Has anyone managed to have the same productivity as...

Of the twenty candidates, indicate the ones you think will prove most significant for future QG research. I've included two papers from earlier in the year which I mistakenly overlooked when they first appeared. Since the poll is multiple choice, it's possible to vote for several papers...

Question For (i) I assumed that the light was plainly polarised as there is only a difference in amplitude For (ii) There is a negative sign infront of the amplitude which I ignored as it doesn't change the polarisation but one is cos and the other is sin, so there is a phase shift of...

I am a undergraduate student now and I have joined in a project in my college. I was assigned a job to simulate the deformation of an elastic membrane given the boundary and the exerted forces on it. It seems to be a homework problem and quite fundamental, but I really have spent much time on it...

As many of you may know, ray tracing was first introduced by Turner Whitted in 1979 in a paper titled "An improved illumination model for shaded display" (can be found on ACM digital library). On the 2nd page, in part 2 (Improved Model) there are a number of fairly simple vector calculations...

I am starting University in September, 2014. I have some knowledge already on classical mechanics as I took optional Applied Math courses (called Mechanics 1 and Mechanics 2) in my mathematics A-Level. I am also self-studying the book Classical Mechanics by Goldstein, Poole and Safko to gain a...

Hi y'all, I am new to the physics forums. I really like Astronomy and Physics. This is a sort of a homework question but I couldn't find the right category to put it in. I have an english paper due soon and I need to find a topic. The paper is supposed to be about a controversial issue. I've...

Hello, could someone please explain to me what happens between (3.6) and (3.7). In specific, I don't understand how substitution results in l^2/pie^2 and also what do they mean integrating over radial angle. And the x next to the dx at (3.7), where did it come from...

Homework Statement I am looking for reliable sources with decent information on monopoles, this is a freshman research paper. I am just looking for books websites and any useful information on the topic. thank you Homework Equations The Attempt at a Solution I've gone to the...

Well, what do you think? And why do you think what you think?

I will, however, point out that PLOS ONE rejected the paper (yay!) and that some Elsevier journals accepted it (jab!) http://www.sciencemag.org/content/342/6154/60.full

So, if we start with logarithm ln(2) assuming a base of 10, how would I solve this without a calculator? ln(2) 10^x = 2 And I get stuck there without a calculator. I could .. ln(10^x) = ln(2) x ln(10) = ln(2) x = ln(2) But that gets me back to where I started. So, how would I go...

http://arxiv.org/abs/physics/0511172v2 "Instantaneous Interaction between Charged Particles" by Wolfgang Engelhardt Submitted to Annales de la Fondation Louis de Broglie Has this paper undergone a good process of peer review? It seems in violation of Special Relativity.
