I have been searching for some 11" Westronics chart paper CT014650-00 as the supply for the control room is apparently down to the last two rolls (will last until about February sometime). A switch to digital is in the works, but will take some time. Any help/leads would be appreciated!

Hello everyone! I am trying to replicate a folding machine, just as a fun project for home use. I understand this simple idea of a folding machine, and I know which measurements I should take. The question behind this project that I simply can´t understand is the spring linear clamp which...

Hi How do I use this formula: ni = (e^(B*(eH-ei))-1)*e^(-0.5772156649..) from this paper? https://ui.adsabs.harvard.edu/abs/2018DDA...49P...2C/abstract According to this site, (n0,n1,n2,n3,n4,n5,n6,n7) = (3,2,1,1,0,0,0,0) for N=7: https://bouman.chem.georgetown.edu/S02/lect21/lect21.htm Does...

https://arxiv.org/abs/1910.12817 As a layman I've come to share this paper, mainly to garner the opinions of others to see what you all think, it was fairly insightful and seems interesting at least.

https://www.sciencemag.org/news/2019/10/new-universe-miniproteins-upending-cell-biology-and-genetics Miniproteins are defined as proteins with relatively few amino acids. Until recently short DNA sequences that could code for a tiny protein were pretty much ignored. By definition. For...

Hi, We all have paper documents containing our personal info: general receipts, regular mail, etc., that we don't want others seeing. I have taken mine to a place that does shredding, but the cost is starting to add up. I can't realistically start a (controlled, of course) fire. I asked the...

Does paper, for example, old books, or any type of paper that is commonly used, could it trap any acteria/microorganism/virus etc over time?? How to "clean" paper?

I came across a problem regarding a paper being rolled into a tube. When a piece of paper is rolled into a tube and then left to unwind, it is always seen that the unwinding happens in jerks and not smoothly. Why is it so? What I have thought (and thanks to some discussions on reddit), that...

I am no engineer, just a physicist. I usually do not work with such problems, so I basically do not know what to look for to begin with. My question/questions goes like this, take the following situation: Fetch a paper, such single paper is easy to bend. If one takes glue, and glue this...

I'd be interested to hear comments from the forum on this paper. Is it a significant step forward? I haven't been able to make up my mind.

I would like to read about the Alcubierre warp drive. Is there a good introductory paper? I have done some GR, round about 8 months worth in undergrad [mumble] years ago. And my honors project was on interior solutions for stellar collapse. So I'm OK with GR at about the speed of Weinberg's...

I am currently reading a lot of papers about ion trap. I have searched some advices about reading paper. They suggest that I should write down some elements of a paper, such as key contents, research methods, problems, causes of the problems, solutions, innovations, and next steps. However, i...

Hi all, Just had a look at the 2016 paper by Wang, Zhu, and Unruh, "How the huge energy of quantum vacuum gravitates to drive the slow accelerating expansion of the Universe," Qingdi Wang, Zhen Zhu, and William G. Unruh, Phys. Rev. D 95, 103504 – Published 11 May 2017 The paper states...

Hi, I am studying a paper by Yann Bugeaud: http://irma.math.unistra.fr/~bugeaud/travaux/ConfMumbaidef.pdf on page 13 there is an inequality (16) as given below- which is obtained from - , on page 12. How the inequality (16) is derived? I couldn't figure it out. However one of my...

While the now infamous Frauchiger and Renner publication generated a lot of buzz, it was largely concluded that they drew way too premature conclusions with a too wide brush. Especially the topic of its implication that "Single Universe" interpretations were mostly ruled out garnered quite a lot...

Problem Statement: There is no precise problem statement since it's an homework to be done independently, but I will try my best to explain it concisely (I also apologize for my mistakes in English) : I want to reproduce the simulation of the model presented in the pdf file attached to this...

I've been struggling with a somewhat-recent paper by Charles Francis, "A construction of full QED using finite dimensional Hilbert space," available here: https://arxiv.org/pdf/gr-qc/0605127.pdf But also published in...

https://arxiv.org/pdf/1812.06239.pdf In this paper,the authors use ricci flow to construct Lifshitz spaces. But it is known that ricci flow is limited by Riemannian manifold, which has a positive metric. but in this paper the author use ricci flow in a lorentz manifold, whose signature...

should n't it be a maximum number to achieve less than 0.5% uncertainty for the last question as you add more disks would there not be more uncertanity therefore as the number of disks for 0.5% is 9.5, 10 would give an unceranity of greater than 0.5% so it should be 9? the answer is 10.

I assumed that i had to take 5 time constants which would give the time taken to charge fully i assume then divide by 10 giving me a total number of readings of 34 , the answer is 6 yet they only used a single time constant to determine the number of readings? as this give me an answer of 68 or...

I am not sure in which direction this induced current would be I am assuming you have to use the dynmo rule or the right hand rule as this is the induced current, and the soft iorn core will cause a force to be produced in the coil which causes the current. If so in which direction would the...

As you can see when the switch is open it measures the voltage across the battery or emf I am assuming when calculating the internal resistance when the switch is closed voltage is 6 right so the internal resistance is 6/2 =3 which is not correct. answer is A Does this mean when the switch is...

https://www.ocr.org.uk/Images/471908-question-paper-unit-h556-02-exploring-physics.pdf 24 A right near the end there is energy relased in this reaction of nuclear fusion but they want the binding energy per nucleon does that mean the binding energy released, as a gamma photon, per nucleon of the...

the answer is 2.16*10^-11 what i don' t understand about the question is why did they not use the constant Eo 8.85418782 × 10-12 in this case as there is a insulator occupying the area inbetween does that mean then their is no free space ?? Also in this equation the variable A is the area of...

I thought some folks here might be interested in this new paper in PNAS. https://www.pnas.org/content/pnas/116/20/9785.full.pdf J. Nathan Matias, PNAS, 2019, vol. 116, no. 20, p.9785–9789. Abstract: Theories of human behavior suggest that people’s decisions to join a group and their...

https://arxiv.org/abs/gr-qc/0306101 I am now reading this attached paper. But i can not get energy result(2.8), and I calculated it and found it is zero. here is my process: firstly, i use Gauss law and rewrite the (2.6): ##E=\frac{1}{8 \pi} \iint \chi_{0}^{0 \beta} \mu_{\beta} d S## where µβ is...

If i were to take one point as my origin and draw the two momentum, one for the initial collestion and one going from the wall after, from the origin point, then drawing horizontally i would get the answer as B as the resultant? Should i assume that for any resultant vector the direction can...

The answer is f/square root 2 If F = 1/2l * square root ( Tension/ mass per unit length ) ---------> this becomes I am assuming 1/2l * square root ( length * Tension/ mass ) this would give an answer of F yet the answer is F/ square root (2)

I am attempting to write a software app based on a research paper: "Predicting Ambulance Demand: a Spatio-Temporal Kernel Approach" by Zhou and Matteson . Here is a link to the paper https://arxiv.org/pdf/1507.00364.pdf . I have questions on how to go about implementing the equations. In...

A couple of questions on this. How would the sound get reflected back from the surface of the water? And therefore create a stationary wave would the sound not travel though the water at a faster speed then reflect back and intefere? Or does a small amount of the sound reflect back? Part B...

Can anyone please provide me the paper by Peebles,P.J.E in 1980 and 1993 where linear perturbation work is done...I am unable to find it... Thanks. Or if possible the link to the books by Peebles ""large scale structure of the universe"" and ""principles of physical cosmology""

This question is a bit werid because would there be a resulatant electric potential equal to zero as we have a positive and negative charge in which case there's no neutral point. As E1-E2 , they have to be acting in oppostie directions , in this case would they be acting in the same direction.

The spring constant of a helical spring is 28 N mñ1. A 0.40 kg mass is suspended from the spring and set into simple harmonic motion of amplitude 60 mm. i use the equation 1/2 change in extension times by force where the force i assume is mass times by 9.8 but the mark scheme uses 1/2 kx ^2 and...

Consider a block on a sheet of paper. If the sheet is pulled without sliding the block, who has done work on the block (since it has undergone a kinetic energy variation)? I can not see another force doing work other than the static frictional force on the block.

Hello. I'm trying to pin down something Stephen Hawking was referring to in his book, A Brief History of Time. During the next few years I developed new mathematical techniques to remove this and other technical conditions from the theorems that proved that singularities must occur. The final...

I am re-reading paper(s) by Huw Price and Ken Wharton that present an interesting explanation of entanglement. I will see if I can paste a link, otherwise one can find them on arXiv: one is for example, “Disentangling the Quantum World”. The idea is that there could be retro-casual communication...

Hello everyone,I have been working on a project for the last two and half years-maybe three (irregularly), since I was an undergraduate. I nearly finished the project, and I am not sure if it is worth publishing or not. It is a correction to a space flight using one specific phenomena. As far...

Can anyone please suggest which books or articles can be taken which would start from a preliminary one for a newcomer like me for understanding the Brans-Dicke theory . Thanks.

... effects the first author.I am in the process of completing my writing for my PhD and will be submitting my papers to the journal shortly. I would like to understand more how the number of authors on a paper affects the viewed contribution of the first author.I have two situations at...

Wald and Zoupas discussed the general definition of ``conserved quantities" in a diffeomorphism invariant theory in this work. In Section IV, they gave one expression (33) in the linked article. I cannot really understand the logic of this expression. Would you please help me with this?

I've been up all night writing and I want to go to bed, but for the life of me I can't find the paper or even the title of the paper that has been referenced in another paper. All I have is... M.A. Margulis, A.N. Maltsev. Russ J Phys Chem, 42 (1968), p. 1412 Which should be enough to locate...

I'm writing a thesis for my high school research paper on dark matter. It's difficult to come up with a claim that is argumentative, engaging, and related to the research I've done on the scientific process in relation to theories about dark matter. Do you think I could reasonably argue that...

Firstly I apologise for the most basic of questions... I want to know the odds for the game Paper Rock Scissors. What are the odds of winning What are the odds of drawing Thanks in advance :)

Hi, Anyone here still buy paper technical books? Most of the material in them is available on the web, although nor in the organized format provided by the book. So it would seem for it to be worthwhile buying a book on topics one is mostly unfamiliar with, in that the value of the book is in...

Who can help me? My paper was submitted to Physical Review Letters in October 25, 2018. But the paper first rejected by Associate Editor of PRL in October 30, 2018, and he gave me a few comments on my manuscript. But I found that his comments were incorrect, so I resubmitted my manuscript to PRL...

I teach group theory for physicists, and I like to teach it following some papers. In general my students work with condensed matter, so I discuss group theory following these papers: [1] Group Theory and Normal Modes, American Journal of Physics 36, 529 (1968) [2] Nonsymmorphic Symmetries and...

Hey, This is more of a discussion rather than a question. A lot of movies (e.g. interstellar, Event Horizon), have a go at trying to explain how the Warp/Alcubierre drive could work, and usually, the argument goes like this: They take a point A and a point B, connect them with a line on the...

I'm writing a mathematical paper on time dilation. Does anyone have any suggestions on how to incorporate math into the topic? I'm considering applying a Loedel diagram. The emphasis needs to be on the math, and not the physical aspects, though they can be introduced through the use of math. The...

Does anyone have any recommendations for databases or other (presumably online) resources that I might use to determine citations of a particular scientific paper. That is, I wish to see not only how many times a particular paper was cited, but I would also, if possible, like to see...
