I have just recently started learning about quantum contextuality and can only seem to find examples where contextuality is need to explain measurements of spin. So I am curious as to whether quantum contextuality only applies to measurements of spin? Also, If someone could clarify where the...

I am at the moment working on a project in which I try to minimize the annual running costs of a chemical manufacturing plant. To predict annual running costs I created a model with over 50 inputs, including things such as the type of chemicals and equipment used at different points in the...

I hope this question doesn't have too obvious of an answer. Basically, I still cannot grasp why Bernoulli's equation applies for wind tunnels and pitot-static probes. According to my textbook ("Introduction to Flight" by Anderson), Bernoulli's equation holds only when comparing two points...

1. The problem statement, all variables and given/know Say I have a can of water, and I am rotating it about its central axis at a constant angular rate. The water in the tank should make a 3D almost parabolic curve as it touches the the walls of the tank. Can I use Bernoulli's equation along...

Suppose y is a positive vector. Let p and x be two positive matrices with N rows, where ##p_j## and ##x_j## denotes the j:th row in these matrices, so that j = 1,…,N. Does the following hold: \inf_{k=1,...,N} [\sup_{l=1,...,N} [p_k(y-x_k)]] = \inf_{k=1,...,N} [p_k(y-x_k)] where ##p_k(y-x_k)##...

Hi I'm a final year MSci student (kind of an undergrad masters) in physics and have been thinking about my next steps for a while now. I have a high 2:1 average from my first 3 years and I was just wondering if getting a PhD is realistic at all (what with all the impressive results other people...

Hello! me and my friends were discussing a few ideas earlier this week and then we suddenly started talking about Einstein's biggest mistake. I was a bit lost because I am not all that familiar with the Cosmological constant and I was wondering how can probability be applied to that mistake?? I...

Hello everyone. I am glad I came across this science oriented Forum site. I actually get there from Google and what I am deeply curious to know about is the amount of Maximum Voltage my 3.5kg Air Core Electromagnet can bear. The Core of the Solenoid is 120mm in height and 13inches in...

Because I'm only in pre-calculus right now (I'm still not in ninth grade yet), I haven't been able to find a way to back up my theories on physics which are mostly based off of reason and logic (I know this is a bad way to back up my theories, I just want to know what you think of them and how I...

Hello, everybody. I'm an undergraduate student interested in QFT (especially CFT, String theory, quantum gravity etc). I have already worked through several serious books in QFT and related topics of mathematics (including all problems from books). Of course I don't mean I'm an expert for now...

Hi first post so forgive any break in widely accepted conduct, Currently involved in a physics competition one of the question is to investigate geysers. Time and time again I have stumbled upon reference to Clausius-Clapeyron relation. Probably the best source I have come across is a youtube...

Ideally I'd like to apply to graduate school for physics (leaning towards Astrophysics or Condensed matter); however, I don't think my course work or research is sufficient. I'm already using an extra year to complete the degree (I changed to physics the end of my Sophomore year) and wouldn't...

So my question is when to apply conservation of angular momentum?When there is no external force ,right?But in the case below A mass m moves in a circle on a smooth horizontal plane with velocity v0 at a radius R0. The mass is attached to a string which passes through a smooth hole in the plane...

Greetings all, I'll be applying to grad school in the fall, and I am uncertain on how to proceed. By the time I graduate, I will have done research with an AMO theory group for four years and will have four publications. However, all of these publications are on numerical work/methods, not pure...

Can we apply Euler's Equation and continuity equation to compressed air flow from tank or orifice.

So it seems straightforward to me that if time dilated, then so would size, mass and energy, but I don't know how to prove that mathematically. I understand the concepts of special relativity and the lorentz transform, and why it is applied to time, but I can't recall or figure out why Einstein...

My temporal agreement is coming to an end and there's an opening in Supply Chain for a bit higher pay grade. However, I'd like to work as a Project Engineer more but there're no openings. Should I apply for the job anyways just to gain some more experience in a hope to move up in the future?

we can use avogadro's law and gay lussacs law to find atomicity of gases but what about solid elements

Hello! Well, I am in trouble with this question for some time. I am making a simulator with autonomous cars and its movement is done applying constant impulses to the wheel. My question is: if the vehicle is in the intertia state and I start to apply this impulses, the vehicle will assume a...

The electron paths in the path integral formulation of qm are in ordinary space-time. The end-points of the paths in the steady states must be in ordinary space-time as well. The electron's potential is exact or nearly exact either by measurement or by calculation. The electron's locations...

Hi! Does the Lagrange equation ONLY apply when the constraints are holonomic? What about the constraining forces acting on the system (i.e. normal force, or other perpendicular forces), do they make a system holonomic? What about the Lagrange equation with the general force on the right hand...

I'm currently a master student in the field of physics, so indeed it's not in US instead in Europe. Now I'm approaching the end of my master studies and planning to go to a PhD program. I have found more than one destinations (which exclude my own current university) which seem to suit my...

Dear PhysicsForumers, I will be applying for University soon. I am in a dilemma now. How do you know if physics is for you? I mean, i do like physics but I really have no idea if I'm able to make this last me a lifetime. How do you really know you don't like, but LOVE physics? I have been...

I made this pic to illustrate my problem. A spaceship (labeled B) departs from a space station (labeled A) at 80% the speed of light (0.8c). A applies the time dilation principle and calculates that B's clocks are running slower than his. Some time later a smaller craft (labeled C) detaches...

My question relates to wave/particle duality. If light is regarded as possessing both wave like and particle like properties, and visible light is just part of the whole EM spectrum of radiation, is it correct to say that radio waves for instance, ( being themselves part of the whole spectrum...

I'm reading Halliday's chapter or rigid body rotation. In the derivation of Newton's second law for rotation, it is assumed that the object is hinged about some axis ( the connection would be a frictionless pin). The law is derived for such a connection, but is later applied to objects that...

Hello everyone, A university has two positions open: one is tenure track and the other is full time year-to-year. I am definitely fit for both, but I probably have a higher chance getting the full time (non-tenure track). Should I apply for both or it is better to just apply for the one I have...

Hi, I am filling up graduate school applications, but I am asked to list the universities I am applying for. Any ideas about the reasons they ask us? Should I tell them? I am afraid this information will affect the admission in a bad way.

do any of you know how it would apply ?

I know escape velocity. in order to get out of Earth's orbit the object has to maintain 11.2 km/s speed. But If I want to throw a 1kg stone out of orbit... how much force I have to apply?

I'm beginning to apply to grad schools (primarily in observational or computational cosmology and extragalactic astronomy) but have a deep interest in M-theory and quantum gravity although I haven't been able to study it. I very much enjoy theory and think that I would find studying M-theory or...

Hi! (Wave) Find an exact asymptotic solution of the recurrence relation $T(n)=4T \left ( \frac{n}{2}\right )+n^2 \log_2{(\log_2 n)}$, using the master theorem or show that the master theorem cannot be applied. In this case, the master theorem cannot be applied, right? (Thinking) But, how...

Can anyone tell me if the following is correct? Traveling directly towards a source of light at some constant speed, we will measure its frequency to be higher (compared to rest frequency) than what we would expect when using Newton’s laws. Just as traveling away from the source, we would...

I know when the initial state (##\Psi(x,0)##) is given, ##\frac{d<x>}{dt} \not=<p>##. I thought you can only apply Ehrenfest's theorem when ##\Psi## is a function of x and t, however it seems like you can also apply it to the time-independent part (##\psi(x)##) by itself as well. Can someone...

What I mean by this is the following: -know what the inside of a closed shape (defined by an equation) is -recognize objects in a picture (2d plane?) using parameters -know the relations of a certain variable in a group -a system in which the input changes the output but at the same time changes...

For example; Please tell me which are false and true. If false explain why, don't just say because so and so said so, please EXPLAIN the concept otherwise I will never learn or explain the true answer! Can infinity odd or even? If not what state is it in? Or the fact that it is never...
