Hello, I am looking for a comprehensive resource (paper, book or any kind of document) that contains the most relevant properties of most nuclear fuels. To be more specific, the information i am looking for are thermophysical properties, chemical compatibility with other materials and...

I would love to read about the different experiments that deal with the collapse of the wave functions and related items. Maybe summaries, I definitely don't want to get into math or anything. Just what causes it to collapse, what doesn't, can it partially collapse, can it collapse in these...

I am aware of the Newtonian model of Gravitation and I am interested in Relativistic Mechanics. I do not know anything about relativistic mechanics other than its more "accurate" at modelling gravitation and that it "reduces" to the classical formulation in some cases. I only want to be able...

Hello, I just learned the bases of IUPAC nomenclature and I couldn't find a good and reliable resource for problems to practice. if you know one please share it with me . thanks.

A lot of fictional examples of interstellar spaceships, be they generation ships or sleeper ships, have some sort of arboretum. However, those often just tend to be places for recreation, like a forest for joggers. Or, if the ship is transporting any animals, too, those might inhabit the...

Is there an online data resource for electrolyte conductivities showing molar strengths and temperatures? thanks.

Hey, I realized there are some parts (okay, a lot of parts) of Physics that I can't learn more about until I actually get a bit of practice solving PDEs. I'll cover it 'properly' next year but for now I'm just interested to learn about the most common solution techniques, types of boundary...

I want to take some courses that involve heavy math, so I have been learning maths on the khan academy site: precalculus, calculus, statistics etc. But one fundamental area of maths the khan academy site doesn't have is a course on linear algebra. I really need to learn and use linear algebra in...

I am planing to change my field (in PhD) and learn Machine Learning to differentiate different phases of strongly correlated matter. I learned Monte Carlo method in my MS and have intermediate level knowledge of topological insulators. Before completely getting into Machine Learning, I want to...

Hi all, can you recommend a textbook or other resource with comprehensive (meaning spanning multiple subjects) and challenging physics problems and also the solutions? I have already worked through Giancoli (no-calculus), Ohanian (calc based) and the two dummies workbooks. I have been working...

What I understand is, I have written something like this myself. What is a Static Proxy and a Dynamic Proxy then? Also, What is a Transient Proxy and a Persistent Proxy?

I am wondering if anyone knows of a good resource to see Newtons first law in action. For example, a block being pulled by increasing force until it moves?

I am looking for some interesting questions on quadratic residues. Anyone know of any resources for an elementary number theory course. I am not looking for drill problems to practice but some important results.

Hello, Can someone please let me know of a resource (book or other) that explains how to use ANOVA in linear regression? I didn't even know what ANOVA was until some days ago so I'm looking for something that explains it thoroughly with deductions. The resources I've read focused solely on...

Here's a simple article that presents the case that nuclear is actually a renewable resource. An excerpt: Any thoughts on the matter? Do other countries consider nuclear as renewable? Japan only comes to my mind.

Hi everyone, Does anyone know of a good intuitive resource for learning Yang-Mills theory and Fiber Bundles? Ultimately my goal is to gain a geometric understanding of gauge theory generally. I have been studying differential forms and exterior calculus. Thanks!

This is the code for Sensitivity Analysis via Rosenwasser's method. Code was for my Masters Thesis, so maybe it will be useful to someone in Dynamical Systems or Modeling with ODE's function ode45_both_age %-------------------------------------------------------------------------- % Solves...

Hello all. This is my first post. I am very passionate with physics even if i did not study them at university. I studied administation and another degree in economics and politics. However, i love physics so much and i decided to learn more about this subject. So, i searched MIT's undegraduate...

About to start reviewing for a math test but it has been ages since I was in school. Hoping some of you math savants could help me out. Will hope to understand and be able to complete these two exams. Starting with the first one below. (Do you guys know of a better exam to test and know...

Hello, I'm using James Stewart Calculus 8th edition. I love the book, but the lack of the student solution book. I bought it and is a great source. The problem I'm having is that some problems are simplified so much and they skip steps, which for me it frustrates me. I was wondering if there...

Classical mechanics: a minimal standard course by Sergei Winitzki. It is not probably going to help you if you already did not know the subject but is a great refresher nonetheless. He also includes a differential equations refresher that I found invaluable. Looks like he has a ton of other...

Hello, May I ask any civil engineers on this forum for their input of pros/cons of specializing in structural / water resources engineering? I am having a hard time choosing between the two because I really enjoy both subject. I enjoy both topics and I am afraid that if I choose one over the...

My class is currently doing thing like centripetal acceleration, momentum etc. and I am not quite getting it. We are also meant to know how to rearrange and combine formulas really well, but I have missed a lot of algebra on previous years so I only know the basics... Can someone please...

I've been looking for quite some time for some tutorial/video online explaining a working circuit. I mean, consider some simple analoge circuit, with resistors and voltage dividers, caps, maybe even transistors etc etc... If this circuit performs some understandable task, then what do these...

Hello, I was wondering if there exists some videos that explain quantum mechanics. Something similar to Khan Academy, but that website only has introductory material. I am not looking for online lectures, but more like Khan Academy or some sort of step by step problem solving skills that is...

What are your opinions on this book? I know that many physicists like to present even the experimental results of quantum mechanics in a distorted way; does this book do so? All I am looking for is a resource where I can learn, in layman's terms for now, about quantum mechanics. I don't want to...

I haven't found the link for Mathtype yet, has anyone else tried to find it yet?

As per another thread I have mentioned that I am looking for information on Lie groups (and related Algebras). My personal library has come up dry in my Math texts, and the Physics texts where this comes up are so brief in their Mathematics that I can't really glean any useful (new) information...

I was planning on using Richard Feynman's lectures on physics to study for high school ap tests on mechanics and electromagnetism. I don't know how in depth Feynman's lectures go, since there are no problems but I've heard it works when you're trying to grasp the material. However, I don't know...

As titled I am mostly looking for logic puzzles that doesn't require too much indepth mathematics, but rather creative thinking to get to the solution example of problems I am looking for: the chessboard corners removed problem is it possible to use fewer than 6 cuts to get...

Hey, I've been struggling a little with rotational mechanics in my AP physics, any ideas for good resources to help? Thanks a lot in advance.

Greetings everyone, I know this is not the right place for this post but I cannot post in the science education subforum so I post my question here. I need a good resource - textbook, online resource, video lecture etc.- that explains the multivariate calculus really well; the topics I want...

So I am trying to learn this. It is not making sense to me. Every single resource I have found tells me I need to make some weird substitution, and then it becomes a differential equation that has the Airy equation as a solution, and then skips to finding the energy eigenvalues as a function of...

Greetings, I learned E&M from Griffiths, and for the most part I understood everything - I am very comfortable using Maxwell's equations, at least in the E and B form. However, the same is not true of D and H, which I really don't understand at all. The reason that I am having trouble...

Next semester, I need to take Calc 3 to finish my AA. However, our college will not be offering it at that time, though they know of an online course I can take. Since I know an online course is unlikely to provide the support needed to really get the material down, I am looking for a decent...

Resource to supplement physics I being taught through "Spiral Physics" I just started Physics I this semester. Though our instructor has given a ton of downloadable PDF files to supplement our textbook, it is all information to read through and study. He has given us absolutely no practice...

I'd like some help working out the probability of my model animal finding water in a day. In my 'model' there is a square landscape 17km^2 The water pool is a circle of 500m radius (so approx 0.7854km^2) So in a one off shot the chances of hitting the water is 0.7854/17 = 0.0462 right...

I'll be starting a summer research thing soon which involves using VASP to do materials science/electron structure calculations. I've only taken a semester of quantum mechanics. What are some good intro resources for this subject area?

Homework Statement I have a chemistry teacher who discourages students from asking questions (long story, but he's just not a good teacher). We have an online textbook, which fails to explain a lot when it comes to formulas. One thing I want to understand is what the different letters and...

I'm a senior in high school currently taking AP Physics BC (mechanics) without having taken a physics course previously. I normally do well in my classes as I'm 10th in my class and am taking the most difficult level of classes I can. I can't say this for my AP physics class, which I currently...

What would you guys say is the best book to self-teach oneself classical physics .. or a few books in conjuction? I am currently using Physics for scientists and engineers by Serway and I am not sure if this is good enough? THanks !

Does anyone know where I find second order damped wave equation worked where the overdamped, underdamped, and critically damped cases are all taken into account? I found resources where they throughout the overdamped and just focus on the underdamped.

First post here in PF, so forgive me if this question is in the wrong place. I'm a student in computational plasma physics. The code I work with utilizes magnetic field aligned coordinates, and as a necessity, it is sometimes useful to convert between spatially regular coordinates (cartesian...
