    Metal inside a microwave oven -> ice?

    of course I assume you're not lying and you don't experiment with this stuff under hallucinogens, the fact keeps being puzzling...

    Metal inside a microwave oven -> ice?

    ok... I admit of course I know little about atomic level behaviour in phase transitions, though it seems still very unlikely, and unreasonable; you're sending microwave radiation centered around the resonating frequency of a water molecule (ideally) and you tell me that by sending energy inside...

    Why Is My Runge Kutta Implementation Not Working for Car Simulation?

    I have it! It finally works! Thank you again, I'll soon try out some different dynamics and see what I can get out of it.

    Measuring temperature in a microwave oven

    a thermocouple I guess will be metallic... that doesn't sound that smart, though I know little about microwave ovens. btw, this led me to asking myself: would any measure you could get be of any physical significance? we usually call it thermodynamics, but the meaning of a measure outside...

    Can Plasma Be Less Dense Than Vacuum?

    imho density is associated with mass per unit volume, so...by definition nothing can be less dense then vacuum. Maybe I'm not understanding what you mean...

    Why Is My Runge Kutta Implementation Not Working for Car Simulation?

    well, actually we have many different safe distance models we are working on, and the dynamics itself is all but done, there are many different models that are worth a try, the one I'm using is one, it doesn't take into account reaction times and it's linear, but before switching to a more...

    Why Is My Runge Kutta Implementation Not Working for Car Simulation?

    they say the proper formula is this s = v^2 / (2 · g · k) BUT I didn't want to be a square function of speed but a linear one, and putting all constants equal to one... this is not nonsense of course, everything might make sense dimensionally provided you multiply it by one the right number of...

    Average total energy of 3D harmonic oscillator in thermal equilibrium

    sorry but I fail to understand: a molecule and a 3d harmonic oscillator are two different things: the classic 1dimensional harmonic oscillator has a potential equal to kx/2, for a 3d harmonic oscillator in cartesian coordinates the potential is a function of the distance from the origin so...

    Metal inside a microwave oven -> ice?

    WHAT? I don't believe this...I firmly stand behind the second law of thermodynamics.

    Question about current in an infinite circuit

    well, reality is a totally different animal. a REAL generator will have an internal resistance, no wire will have no resistance at all, though for a small circuit it could be negligible compared to that of resistors, so you will have no infinite currents. And since now your system does have a...

    Why Is My Runge Kutta Implementation Not Working for Car Simulation?

    numbers in a calculator are just numbers; I want the safe distance to be a linear function of speed, and that's what I'm getting. How would you do that? The algorithm DOES reflect reality (somehow) it's called a "car following" model, and there's plenty of literature about that, and you're...

    Why Is My Runge Kutta Implementation Not Working for Car Simulation?

    I know... I'm trying to improve my programming habits, bur sometimes I just get lazy. no, C is ampli/omega, so the algebra was right, though as a matter of fact I have no use for that PI factor now, I'm removing it well, that doesn't make much sense, I'm not comparing quantities, I'm making...

    Why Is My Runge Kutta Implementation Not Working for Car Simulation?

    sure; actually the force function now has no use for the time variable, but in a previous version the leader car motion was determined by the force function and that's why I'm passing time to that, it's actually a mistake, but I'm pretty sure it's not that relevant, in the program now, and...

    Why Is My Runge Kutta Implementation Not Working for Car Simulation?

    I've been browsing the forum, but I haven't found a way to solve this thing, which has been frustrating me for quite a while, I'm trying to develop a simulation of cue formation and propagation on cars on a single lane road, and of course, I have to compute the acceleration of vehicles obeying a...
