This is one of the cases "chemistry vs. physics" approach sounds different. The word "actual" means nothing to me. All we do is try to explain a complex reality with some models. Whether it is Schrödinger or Dirac eq or LCAO, etc... In this sense every explanation is an approximation.
They are as real as "actual" (??) wavefunctions. Schrödinger equation is a linear equation and linear combinations of solutions are perfectly valid solutions.
I take a wire of metal X which has a diameter d. Let the total length of it be L and I roll it around a cylinder with diameter D to create a spring. Is it possible to predict the spring constant of this system (and relate it to the elastic constants of the metal)?
Has anybody seen/heard/know a...
Actually the original olympiad preperation question was an equivalent problem represented below:
Magnetic field from below, charged bob with mass m. There is no Earth rotation so no Coriolis term but an equivalent Lorentz force perpendicular to the plane and proportional to the velocity. The...
I start by the definition of Coriolis force. The ##\Omega## was first introduced there. I am not sure what is your point really? May be you should elaborate your objection please.
Sorry, I should have made last point more clear: what it tells us that this ratio ##\omega/\Omega## is the number of oscillations required to complete one cycle of the plane rotation. From this since you know the period of SHM as ##2\pi/\omega = T## you can get the period of the plane rotation...
In many standard texts the behavior of Foucault’s pendulum is solved by adding the Coriolis force term to equation of motion and deriving two coupled differential equations. Here’s an alternative approach:
4 assumptions are made:
Mathematical pendulum (point mass attached to massless rigid...
OK, 1955 is definitely related topics but 1978 is a good example of two completely different subjects. Thanks for pointing that out. (And even better they were honest in their presentation by not forcing them under a vague umbrella term.)
Sorry for the speculative title but, I kind of think so. Both subjects are great discoveries and maybe they deserve the prize on their own (maybe not that is not my point). My point is how are they connected to each other under the vague umbrella term: "Complex systems". Their subjects are WAY...
Hi guys,
I think I have persuaded the administration to install a Foucault pendulum in my university building where a high roof and open spaces are available. The thing is I have to project it with design, cost, etc. Those are domains which I don't have much expertise as a simple physicist. So...
Oh sorry, I should have been more clear. What I mean is the difference between the work functions of metals create some activation in the contacts leading to higher risk of corrosion, oxidation (or even electrolysis if working in an aquaeous (or damped?) environment) which eventually might alter...
