I am looking for any resources which explain the RSA algorithm for the layman. I have found a number of sources but they all tend to end with a morass of technical details. This is for a first year undergraduate course in number theory who have covered some basic work on modular arithmetic.

I have extensively searched the internet but failed to find any exhaustive literature on the different collapse models of quantum mechanics.It would be really helpful if someone who knows can guide me on some exhaustive resources for the same.

What would tou suggest as the best resource for learning integrals? I need preferably some practical books videos or youtube channels that deal with application and problems rather than theory. Any thoughts? Thanks

I'm looking to start a healthy diet. I know next to nothing about what that means. I'm going to start studying up on nutrition. I want to structure my diet around what the most sound and up to date science says on the matter. I'd much appreciate the input of anyone with expertise in any...

I would appreciate it if someone could recommend something. I found a boiling point calculator by CalcTool but it doesn't seem that reliable.

My university lecturer is very new, his lectures and notes are hard to follow and understand. He was a replacement to the old solid state physics lecturer and has designed the module from scratch, so it is unpolished in its current form. Can you please suggest some alternative resources...

Hi everyone. I'll start my master's degree in physics next year. My plan is to continue my studies in theoretical condensed matter physics. So I've decided to increase my knowledge in this area. In my undergrad I took some courses like Intro. to QFT and Many-Body physics. Also I have studied...

I've become nauseated with the recent obsession with colonizing Mars, mining the moon or asteroids, and spending resources on intermittent power production from wind, solar, and batteries. I've looked at numerous sources of energy production and have come to the conclusion that instead of...

Hey everyone! I need your help. My new girlfriend is smart, but she's misled and attracted to pseudo-scientific ideas (i.e crystal healing, astrology). I find this fairly annoying. She is a true social scientist though and searches for valid science when it comes to psychology, so I know she is...

Hello, I need to learn how Solid State NMR and X-ray Crystallography work (theory and practical application). I'm primary interested in how those experimental techniques are used to determine molecular structures. I'm an undergrad physics student and I need this to pass my final exam. So if some...

In two months I'm going to take one Physics exam which covers all the undergraduate courses and I must confess I feel quite overwhelmed by the amount of content that there is to be reviewed. In truth I feel that for the purpose of preparing for one exame like this it is not really productive to...

I'm trying to self-study general relativity, but I encounter a problem. I can easily understand the ideas and the results, but there are some things related to 4-d geometry that I can't find, like what are Christoffel symbols and how to solve the equation of a geodesic line. I searched for those...

Hi everyone. Looking to get back into offering private tutoring in physics. (Mod note: changed "tuition" to "tutoring" here and in the thread title.) I used to carry a few textbooks with me and my paper notes with lots of printed exam papers for student to try. I am looking to go paperless...

I am planning to give the MATH GRE. I intend to go to physics graduate schools but I may have to given the MATH GRE according to my college's requirement. I very much like maths, but I'm overloaded with physics related work, including the GRE, since I have been making a transition from...

I am doing a BSEE and going power side. I am also applying for scholarships and bursaries, and would like to be able to talk specifically about power factors. More than this though, I want to understand it. Most of what I've found so far is very specialized and technical. What good resources...

Hello I am in my final year of schooling in South Africa. For Physics, we do a module called Vertical Projectile Motion & Graphs. This section uses equations of motion etc. I cannot seem to find the online resources for me to truly master this section. The sites I have are of projectile motion...
