Howdy, mate! Good day? I'm a 22 yo student of Bachelor's Degree in Guidance and Counseling. You might be wondering why I'm here since I'm not a regular science person, but I'm interested in discovering different, new, attracting knowledge! I might often be online here for many questions. Hope...
I am at a crossroads in my life. After graduating high school, I went into the ministry. I had no plans to continue my education, and I was content with my perfect little Christian-centered world. Eventually, my faith was shattered and I came to the realization that my entire worldview for the...
Hello respected members,
I hope this message will find you all well.
I want to ask a question that I had for a long time, which is: Does the GRE physics have any importance in countries other than U.S? if you think that “other countries” is too unspecific statement then please tell me if you...
Hello respected members.
I hope this message will find you all well,
I have came across a brand new textbook on quantum mechanics by J. D. Jackson, not his previous book (mathematics for quantum mechanics) but a new one edited by another physicist based on his lecture notes... I first thought...
Hello esteemed members, I have a question with regard to what a physicist should study in mathematics.
I tried hard to find a solution to this question but I couldn't, I have just reached to some conclusions I think they are true but I am entirely not sure, thus I decided to put this question...
Hello esteemed members,
Recently I have been using this site for getting help, and I have found it very helpful, thanks to the helpful members who I may not be able to thank them fully.
However, part of my method of studying is to do a self-contained study guide or summary or notes... to the...
Hey, I was just contemplating career opportunities after my Undergrad. I am slightly interested in theoretical physics but I can't imagine doing it the rest of my life. My main interests are nano-photonics and quantum technologies and I am planning to do research in these fields. I am not...
I feel compelled to note a valuable new article in the magazine Science about the task of writing scientific papers in English when your native language is not English. The article is written by a Chinese scientist who did his PhD in the U.K.

This was a trivial question I had (which I posted here on the PF EM Forum: https://www.physicsforums.com/threads/bound-charges-polarisation-of-a-half-cone.1015308/).
As I received no response on the above link I decided to post the same as a self formulated HW problem. Below I have attached an...
My project is on threat modelling and prediction. The use of threat modelling with machine learning. So far I've found articles that use MITRE ATT&CK repository with STIX used with machine learning and data mining with CVSS, but I'm unsure if this is the right track. I basically just need to...
In my textbook on EM, the formula for self inductance of a finite solenoid is given as:
L= (μ(o)* N^2*A * {√(a^2+ l^2) - a} )/l^2 where a=Radius of each turn, l=length of solenoid.
I am having trouble and extreme difficulty in trying to ascertain how this formula was derived in the book and...
I am about to start writing a fairly important lab-report and have a few questions about structure.
The experiment can be broken down into three “sub-experiments”, which have their own methodologies and conclusions. Each involves investigating the behaviour of a different part of the apparatus...
(EDIT: I have also added 2 snippets of the syllabus of the entire Math Physics course in my curriculum as reference).

I wanted to purchase a new math text to expand both my library and my knowledge. I transferred to UCSB College of Creative Studies (it is said to be a grad school for undergrads) as a math major and proceeded to take nothing but full quarter loads of every math class that looked interesting to...
Hi everyone,
My university has completely scrapped an undergrad Intro to QFT course and I am essentially left with no choice but to do self-study with no (worst-case scenario) external guidance.
Are there notes or texts that can be used for such a purpose? Would be a nice bonus if there's a...

I was assigned a project where I need to have a heat sensor send a signal to my phone and cause it to sound an alarm. If my phone is an android what is a good app programming tool for this project, I’ve never done app programming. Would I be able to send a signal from the sensor to the phone...
Is there anyone on here who could help me fill in my gaps in quantum field theory up to renormalization? I know how to canonically quantize a theory and how to use scalars (spin 0), vectors (spin 1) and spinors (spin 1/2) but lack more advanced knowledge like renormalization which I could...
First of all, some background:

Hi,
I'm not used to communicate physics in English, so my language may be a bit off.
This task is fairly simplistic. It's a figure which is held up in points A and B (both having an x and y force exerted on them), and the figure has a joint C. It is depicted in attached files.
The answers...

TL;DR: I seriously screwed up when I was in my undergrad physics program and ended up essentially dropping out. Several years (and 'careers') later, I ended up becoming a software engineer. I make very good pay, but feel an itch to return to science. I feel an urge to to return to school and...
Hi all
In general I'm experimenting with an old split air conditioner which i would turn into some kind of homemade heat-pump.The basic idea is to replace the indoor unit with some kind of heat exchanger so the AC heats up water instead of air ,which in turn circulates over radiators in...
Hi,
I’m currently at college for my B.S. in physics and I’m working toward my minor in bio. My original goal was to go for a B.S. in physics and then through the program offered by my school, get a M.S. in engineering. However, I had a change in heart beginning of last semester and dropped the...
