Observational evidence for cosmological coupling of black holes and its implications for an astrophysical source of dark energy Comments?

Is there any specialize articles that talk about how Astronomy can help learning Math and Physics? In particular, how observational astronomy can help in the learning process of Math and Physics.

I just read Feynman's The Value of Science and really appreciated his perspective. We generally value art, literature, and poetry but if you want to do science for the sake of science people take offense. It takes years to build a foundation before you can appreciate it, so the general public...

Summary: best publishing sites Hello. I have a theory on astrophysics. I want to find the best free website or platform to publish my articles on it. I want the website to be completely free, not asking for fee from me or the readers in any ways, and not having hidden fees either. please...

I've been toying around with a few problems in hamiltonian mechanics that I came up with, they're nothing special but nonetheless I think they're fairly interesting. Are there any student-friendly journals etc. which might accept these sorts of articles? [I haven't written anything up yet, btw 😜]

Hello everyone, I'm a mechanical engineering student, I'm italian, so, sorry for my bad english. In this moment i am studying the following subjects: Mathematical Analysis II (multivariable calculus), Physics II (eletctromagnetism), Mechanical design and fundamentals of structural mechanics...

photoelectric effect is now explained in quantum idea. Why the classical model fails? Are there articles computing it in detail using classical model?

Adding drama and controversy to scientific reporting and written articles for the public is not new new to me. For over 20 years I've seen it in the global warming/climate change discussion. What is new to me is a high level of drama in controversy added to a couple of subjects that are normally...

Is there something that visualizes the connection between different areas of all(/almost all) phyics? It could be easily done with wikipedia articles: every article is a point in a graph and two points are connected if there's a link (one or both ways) between them. Given this, it could help to...

If you have any material (books, links, articles) on transistors i would appreciate that. I am looking for a way to get more general knowledge on subject. Thank you.

Hi, I found this article very interesting, given the loads of question I have posted in this regard in the last months. I cannot recall where I got the link from, and if it came from Bill Hobba in some discussion, thanks Bill! If not, thanks anyway for your answers and contributions. Here is...

I just want to let you know what I suspect I got the virus from. I don't serve on questionable sites, no porn sites or anything close to like that. I read articles on Yahoo front page. Lately ( last year), they start to have articles like "How's you favorite tv stars from the 80s look like now"...

I would like to download articles of my favorite journalists. But they are in their newspaper's website. There are hundrends of article for one author. Is there a practical way to download a author's articles. I have to click hundreds of times. Is there any program for this case? For years ago I...

What's the procedure for commenting on articles? At the end of comments to an article, I see a link that says I must be logged-in to comment. When I click that link, the same page reappears. (And I'm already logged-in, in the sense that my "alerts" are shown when I'm on the physicsforums home...

I saw a link to an article by Edward R. Dougherty, a professor of electrical and computer engineering at Texas A&M, who apparently works in genomics and the cell. Then I noticed that on Public Discourse, he had a whole series of articles. I thought you all might enjoy them, as this guy can...

Hello everyone, New member here, love the site, but it is missing something I'd love ( or perhaps I can't find it ). I'm taking a physics course on Edx and the community TA's write up great short articles that aid in understanding a problem or particular concept. I'd love to have some sort of...

I have seen a number of references to apparent experimental "proof" of wavefunction collapse www.nature.com/articles/ncomms7665 However, I am still seeing propagation of the "Many Worlds" theory, which, and I admit that my understanding is limited, but the MW hass at its very core, a necessary...

I'm sorry but I didn't find any other place appropriate to post this other than General Physics. Say I have downloaded a pdf of a paper that's not open access for free via my university's VPN connection.Is it legal to e-mail the pdf to someone else?

I will be working as an assistant for the first time in my life soon. I wanted to ask your opinions on teaching people to learn from physics journals. When I started doing real research, I think the first problem I came across was that reading journals is hard, and learning from them is even...

Hello, As a person who is really interested in chemistry and physics, I like to learn more about things that seem interesting to me. Internet has bee n a good source for me so far, but sometimes there are papers-articles I want to read, for example in http://pubs.acs.org/ or...

I have seen the graphs of He abundance as a function of baryon number divided by photon number. these graphs are easy to find on any site discussing the BB and BB nucleosynthesis, they are very common and aimed at the general reader.I find it a fascinating graph, I would really like to see how...

I read many articles here about gravity but I can’t find the following specific subject: I need a help to find in this site or any other place, studies or experiments comparing the “virtual gravity” (1G acceleration inside of a spaceship for example) with 1G gravity perceived in the earth. Any...

Hi, I was interested in collecting around 3 very nice chemistry journal articles to use as example/inspiration for students writing lab reports. I thought I would ask here before wandering my libraries' archives for a few hours.

I'm looking for sites with historical journal articles -- ideally in English, but if there's none available, I can settle for the original. Specifically, I'm looking for stuff by (in no particular order, and certainly not exclusively) e.g. Heisenberg, Pauli, Dirac, Schrodinger, Feynman...

Hi I am looking for a good e-ink device with the following features: a. PDF support with annotations. The screen should be capable of displaying one full page with readable font. b. easy navigation to different parts of long article. Navigating by page number would be helpful. c...

The Wikipedia has a project for creating audio articles. https://en.wikipedia.org/wiki/Wikipedia:WikiProject_Spoken_Wikipedia What would be a good way to use audio in mathematical articles?

I have the rather fortunate task of reading to completion Eric Poisson's review article on point particle equations of motion in curved spacetime, http://relativity.livingreviews.org/Articles/lrr-2011-7/ . It's a rather long and very technical review. I've only ever read one review article in...

I am planning to do some work on quark fragment into hadrons, and I have heard some models like Lund Model, feynman-field model and so on. Is there any good review articles on the topic of fragmentation model? (Recent years is better) Best Regards!

Hello, I was wondering if anyone can recommend any good articles or journals with valid and good velocity data for flow from an impinging jet on a flat surface with an approximate Reynolds number of around 75,000 to 90,000? I have looked and seem to have lots of data for heat coefficients but...

Interesting articles online on academia and the "PhD problem" Hi everyone, I've linked here two articles I've found online that specifically address the issue of whether a PhD really prepares its students to careers outside of academia. One is an article from an environmental researcher...

A graduate student I know swears that there is some form of carbon and that it is very expensive to make the fuel pellets, especially to make them smooth for the ablation process. I have read they are extremely cheap but I may be thinking of just the DT fuel and not the pellet. Either way...

I'm an undergrad physics student and have to write an essay on the Higgs boson and the future of the standard model.

Hi all, Recently I read an article called the "History of noise" by Leon Cohen, and liked it a lot. It's essentially of a review of the developments that have taken place in the study of Noise over the past century. I realized that review articles are a great way to get a bird's eye view of...

Before the days of fast internet access, I eagerly made copies of interesting technical articles. I even bound them up using "stab binding". However, the way they piled up was a depressing reminder of all the knowledge that I was never going to take time to investigate. Now that the internet...

I want to find David Bohms original articles on his interpretation of quantum mechanics from 1952. And Paul Diracs 1932 paper on principle of least action in quantum mechanics. I searched for articles at my schools library and I could find articles that had sighted their names but I did not...

I'm a freshman who is going to declare biology as my major oin a few days (the first year was the common year).
