Hey all! I'm new to Physics Forums. I'm going through Hawking's famous 1975 paper "Particle Creation by Black Holes" which presents the phenomenon later known as Hawking radiation. I'm going through it for the sake of my own learning and benefit since the paper is a bit ahead of my edge as a...

http://advances.sciencemag.org/content/2/8/e1600162.full They claimed to have shown that non local causaulity models of QM do not work. But does that include the Transactional interpretation, which is non local and retrocausal?

For my senior project I am writing a paper on the Higgs Boson. Whatever project we decide to do we have to have an accompanying research paper. I am unable to write about anything that I mention in my paper (everything involving the Higgs). What are some related topics that I could do my second...

Is it possible to get a PhD degree if you publish a good paper ? And if so , what are the terms of the quality of that paper(s) ?

If you had something particularly nasty like ##log_{10}(9)## = ? I asked my teacher about how to begin approaching that kind of computation of logarithm. He was not very interesyed in explaining the procedures of estimating the value of the log. Perhaps the procedure went beyond the scope of...

Hello, I have been reflecting over this for the past few days. We can charge two insulators by rubbing them against each other. The two materials end up having an equal amount of opposite charge. For example, a glass rod rubbed with silk will become positively charged and the silk negatively...

This isn't exactly homework or coursework, it is a past paper question that I cannot find a solution to (my university doesn't like releasing answers for some reason unknown to me). The question is attached as an image (edit: the image displays while editing but not in the post, so I'll try to...

Hi guys, This is my first time posting on PF! I have a question on §3 of Einstein's paper "On the electrodynamics of moving bodies."My problem is with the following mathematical statements: Hence, if x' is chosen to be infinitesimally small, or I have just finished high school, and...

This question is mainly geared toward @ZapperZ, since I know you have a good deal of expertise in superconductivity and in STS/STM. I saw this paper in my journal alerts early early last year: http://journals.aps.org/prl/pdf/10.1103/PhysRevLett.115.237002 "Mapping the Electronic Structure of...

In the paper John Corcoran & Hassan Masoud (2014): Existential Import Today: New Metatheorems; Historical, Philosophical, and Pedagogical Misconceptions, History and Philosophy of Logic, http://dx.doi.org/10.1080/01445340.2014.952947, already in the introduction it says, as self-evident, that...

I am writing a paper. I am looking for a journal that: -Accepts theoretical physics papers -Is reputable -Peer reviews submitted papers -Will not charge me very much in terms of a publishing fee (or any other fees) -I keep the copyright on my paper An online only journal is fine. Does anyone...

A Design for a Quantum Time Machine Andrew Gray, submitted 2 Apr 1998 ABSTRACT "In the new ``History Selection'' formulation of Quantum Mechanics an entire cosmic history is selected over all space and time, with a probability for selection assigned to each possible history. As this...

NOTE: I seem to have a dental implant in which there has been a mechanical failure of the abutment, which has piqued my interest in this. The paper is here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4668729/ About 40% down, there is: *** The most commonly used retaining screws are either...

The critical geometry of a thermal big bang Niayesh Afshordi, Joao Magueijo (Submitted on 9 Mar 2016 (v1), last revised 8 Nov 2016 (this version, v2)) We explore the space of scalar-tensor theories containing two non-conformalmetrics, and find a discontinuity pointing to a "critical"...

So I know that AG is 30cm, what else do I do?

Here is the arxiv link. I'd be interested to hear comments from people more expert than I. The claim is that both dark energy and dark matter can be understood as consequences of gravity as an entropic force.

hello, a bit of topic. we're having an exhibition at my university to display outstanding papers. my paper was about my passion for mathematics. I am seeking some ideas to make visitors want to read my paper. I don't want something too childish. I was thinking of making a string model of some...

can dark matter explain Tully-Fisher relation, or is modified MONDlike gravity a better explanation for this? new paper The Radial Acceleration Relation in Rotationally Supported Galaxies Stacy McGaugh, Federico Lelli, Jim Schombert (Submitted on 19 Sep 2016) We report a correlation between...

I have some questions about the first discovery paper that was released about gravitational waves, especially some of the maths. How did they: 1. Calculate the masses of the black holes that merged 2. Calculate the energy radiated away in gravitational waves 3. Calculate how far away the event...

http://arxiv.org/abs/1609.04813 Quantum gravity on foliated spacetime - asymptotically safe and sound Jorn Biemans, Alessia Platania, Frank Saueressig (Submitted on 15 Sep 2016) Asymptotic Safety provides a mechanism for constructing a consistent and predictive quantum theory of gravity valid on...

Every once in awhile I'll change my writing set up to use thicker lead, differently lined paper, type of notebook, etc. I never seem to be satisfied with anyone of them and it can be a hassle trying to keep everything in one place if they're all in different formats. At the moment, I'm writing...

Ok I can't tell if this should go in academic guidance or homework questions so I'll just put it here. I decided to do my high school senior project writing a paper on a recent discovery in physics. I narrowed my topic choices down to either photonic particles, exotic hadrons, or the Higgs. I...

I'm currently writing a paper on the Multiverse. I do have a theory of my own and have made the outline and started working on it. However, the language seems to unscientific, in the sense, its not very objective and crisp. How do i improve the quality of language and content of the paper. Any...

How to submit paper to physical review letter? is there any specific criteria such as recomendation from expert? or can we submit without recomendation?

I am currently writing my first mathematics paper but I don't know how to formally represent and show the process of rearranging a certain equation; for example what symbols would I use etc..?

what is the chemical composition of common processed paper and what does the molecule's structure look like?

So I want to write a research paper and publish it before I complete my engineering degree this year. I have selected the topic which is "Analysis of the voltage regulation of Self excited induction generator using STATCOM". I have collected all the resources required and am also doing research...

robphy submitted a new PF Insights post Relativity on Rotated Graph Paper Continue reading the Original PF Insights Post.

A new paper on arXiv today claims that relationsism allows one to evolve the universe through the big bang. Alas I am not familiar with relationsism, is it related to shape dynamics? can anyone explain? https://arxiv.org/pdf/1607.02460v1.pdf

Hi. I am an electrical engineering student in my final year. I want to write a research or review paper this year before completing my degree. I haven't written any paper before. I don't know where to start. Will someone please guide me? In addition to that I haven't selected any topics so I...

I am looking for a small journal to submit my recent paper. I hope it can 1. have printed version 2. free of publication fee (therefore all IEEE journals are out) 3. listed on SCI It does not matter which country does it belong to. Nor do I mind whether is it small or not. Has anyone any...

My professor wants to give me (and another kid) a problem in quantum cosmology. To that end, he asked me to read through his recent paper that appeared in the Physical Review Letters. He said that I should be able to go through it since all the paper employs is (quantum) scalar field theory...

Many phisicists writed scientific papers at early age like maxwell who wrote one at 14 another one at 16 then at 18 but these 3 papers weren't a new theory or discovery right ? So why a scientific paper is always noted in the biography of physicists if it's not important because it's not a...

Hello, A ways back I was reading something on Aharanov's flavor of QM, Time Symmetric Quantum Mechanics (TSQM), which referenced an upcoming paper. To be covered in that paper was the following. It's been mentioned that within TSQM there are three seemingly mutually exclusive "principles"...

I have recently read a paper called "Engineering of Gravity and Time" for an undergraduate student. It contains a theory of gravity and time depending on rotation. Well.., I think it looks quiet percussive. However, fairly, it contains some worthwhile ideas, especially it answers some elementary...

Trying to move a discussion over a paper I had here too... I'm referring to this paper : https://arxiv.org/abs/1604.05394 and in particular Table 2, the mass of the 2nd heavy neutralino m_{\tilde{\chi}_2} is negative: m_{\tilde{\chi}_2}=-135.3 \text{ GeV} . Can it be a typo? (it has to be)...

I am not sure this is the right forum for this -- I have a question about a particular paper: http://www-users.cs.umn.edu/~sboriah/PDFs/ChandolaCBK2009.pdf The authors describe 4 heuristics that can be derived from categorical data -- this is in order to map categorical data to numerical...

Hello, I'm looking for a free copy of Wien's seminal paper "On the division of energy in the emission-spectrum of a black body", in which he introduces his important blackbody approximation.

Can someone point me to the seminal (or any other) paper explicitly showing and proving the formation of singularities in black holes? I'd like to learn about the exact physical processes which occur during the collapse of a star into a black hole and how the progress of those physical...

I posted this in discussion because it was interesting, IMO, and does not fit anywhere on PF http://www.nature.com/nature/journal/vaop/ncurrent/full/nature17159.html Ritual human sacrifice promoted and sustained the evolution of stratified societies The hypothesis is: more use of human...

Hi. I'm looking for this paper, which is referenced in some papers I've been reading. The thing is I don't know how to get it, or where to buy it. I thought that perhaps someone here could help me. This is it: "Kaltenbach and Kaschke (1993): Frequency and time-domain modelling of light...

I am considering taking a PhD position in stochastic stability and control within the mechanical engineering department at a university which has offered me a lucrative RA. In discussing my topic with my potential advisor he gave me a paper to read this week. After I read the paper it was clear...

As far as I can tell Eberhard and Ross didn't "prove" quantum entanglement can't implement FTL communication in "QUANTUM FIELD THEORY CANNOT PROVIDE FASTER-THAN-LIGHT COMMUNICATION", 1988 (http://link.springer.com/article/10.1007%2FBF00696109). But it's often cited as such a proof, in threads on...

Or will there be a good chance of it being stolen?

I want to write a paper that includes some inovative experiment results. It's a high school project so many things in physics are unknown for me. What topic whould you recomend(based on what hasn't been fully discovered and yet doesn't include complex knowledge of mathematics)?

Can someone help me understand exactly what a0 is in the following paper (page9)? http://arxiv.org/pdf/1405.1283v1.pdf "where a0 ≡ be−∆/2 (60) is a fixed length that can only be determined by experiment." Found it in this article which has a better diagram...

I'm not sure if this should go here. I followed the guidelines of the MIT motor challenge for physics 8.02 and came up with this: I thought it would be a nice example of what one can accomplish with some very basic materials. This could make a nice high school science project in the right...

[Moderator's note: link deleted] Does it have any validity?

Hello all! I am a senior in high school with a love for physics. In English, we were assigned an argumentative research paper with a topic of our choice. So, naturally, I chose String Theory, since it is a semi controversial topic in theoretical physics today. My only problem is that I have a...

Each of the two BHs in the collision brought in matter and energy prior to merge, neither emitting any significant energy prior to merge. Same for the combined BH after merger was complete. So, my question is, what is the source or mechanism for the 3 Sun M worth of energy release into...
