Summary:: I am in second year uni. So I know very basic maths. I need to write a paper. Any suggestions here will also be helpful. The paper doesn't have to be totally original. [Moderator's note: solicitation removed.]

Hi, there. I am starting writing my first paper now. But I do not feel very well. First, my brain is almost empty when I start to write the introduction section. I feel I have many things to say but they disappear when I really start to type. I am afraid the structure of this section will not...

I can choose any topic. The paper doesn't have to be original. Please suggest a simple paper to write which involves math and chemistry. I am in second year university.

Firstly, it might be worth asking if anyone is familiar with the above paper entitled 'Inflationary spacetimes are not past-complete' by Arvind Borde, Alan H. Guth, Alexander Vilenkin? If you are, you might be able to help me with this question. I was doing some reading trying to get a better...

On page 8, I don't understand the last paragraph. It says if ##|A \rangle = U|0\rangle ## and ##|B \rangle = U|0\rangle ## then ##\langle A | B \rangle = 1##. Of course ##U |0\rangle## is a unique state (##A## and ##B## are the same by this definition). So I assumed what he meant was more...

The paper I refer to, I found on the Big Think blog titled "Is human consciousness creating reality? And here is the actual link to the paper. Unfortunately, this paper is too technical for me, hence the request for a review for such a big claim.

Hi Pf I read several years ago an article written by Massimo Blasone. He wrote that quantum physics has a much logical description when it uses two fields one forward time and the other backward or something like that. I forgot in which paper . Did you read it? thanks

hi guys i am trying to write a paper based on someone previous paper in which he discussed a simple electric circuit on some topic , my question is : is it illegal for me to reproduce the circuit schematic using multisim or something and properly cite them in my paper ? or i need their...

A new pre-print makes a sensible and convincing, in my view, argument that phenomena attributed to dark matter are not exclusively or predominantly explained by primordial black holes formed at less than the mass of a star shortly after the Big Bang, by means other than stellar collapse. This...

I have a problem: in the same anime I saw that Senku estimated the time to start burning the paper in sixty seconds, one minute and with a lens. The data is as follows: The lens he used has a diameter of 5 centimeters. The solar constant, assuming it is the same as 3700 years ago, is 1362 watts...

Summary:: Is it possible to publish a paper contradicting Einstein's special relativity in any high-ranked Journal? Which Journal is the best, i.e. open minded, for such a paper? I plan to publish a new theory of electromagnetics in a Journal. The findings are purely through strict...

On another thread, now closed, Intrastellar asked: Unfortunately it seems that thread is closed before anyone pointed out Einstein's papers on this question: A. Einstein, L. Infeld and B. Hoffman, The gravitational equations and the problem of motion, Annals of Mathematics 39 (1938), 65-100...

I read a paper a long time ago. And i forgot who wrote it. The author said that information was not encoded on space time but on the boundaries of regions of space time. there was 3 parts on this boundaries. a space like part (for the initial conditions) . another one for the "out" state...

Stupid question. Is that possible form the style and language viewpoint to write such things in the article: is the environment "Fact" ok?

Hi, I was practicing writing a paper in MS Word 2019 and need your help with few important points. I understand it's little too many queries but they are all related so I thought asking them together would be a better idea. Thanks in advance! 1: Suppose once I was done adding all the...

I'm writing a physics simulation to mimic the old equipotential mapping experiment like this one. I can't find much information on how the voltage across this semi-conducting sheet relates to the E-field. Before I start heading down the path sheet resistance and the resistivity of thin-film...

The correct answer is 'C'. I don't understand why my working is wrong. What is the optimal way to do a question like this?

In class, we briefly discussed those experiments where a paper cup is filled with water and heated, and the cup does not end up burning while the water is able to boil. From what I remember of what was said, although I am not sure I understood correctly, the water has a much higher specific...

A new report based on Hubble Space Telescope observations is a big deal because it presents a new and independent apparent disparity between the lambdaCDM predictions for dark matter phenomena in galactic clusters and what is observed via gravitational lensing. The paper and its summary and...

For Q13 D) E) F), the model I had built was based on elastic collision with the blobs going out of the box, but colliding with air particles and then going back into the box. Thus, momentum would be redirected and it would be higher than what the answer says and kinetic energy would also be...
