    B Time Dilation & Muon De Broglie Wavelength: Explained

    I'm trying to abide by the standards of the forum but I guess I don't see why my questions are considered invalid and comparable to asking chemistry questions using the 4 element "model". If I understand correctly, unlike the 4 element model of chemistry, the de Broglie model: 1) does make...

    B Time Dilation & Muon De Broglie Wavelength: Explained

    I see, so if I'm understanding correctly, basically the only measurable prediction we get from the de Broglie model is the diffraction patterns at the detector, and it would be unjustified to extrapolate this to some kind of actual sinusoid wave pattern of the muon during the interval between...

    B Time Dilation & Muon De Broglie Wavelength: Explained

    Is it not ok for me to ask here about what the logical consequences would be of using the de Broglie model and the special relativity model together?

    B Time Dilation & Muon De Broglie Wavelength: Explained

    I see, thank you for the response. It is evident to me that if phase is independent of reference frame then the number of cycles along a given curve will be independent as well. I have two follow up questions: 1) Have there been any experiments which directly verify this frame-independence of...

    B Time Dilation & Muon De Broglie Wavelength: Explained

    Thanks for the response I'm not sure I understand yet. Maybe a simpler question, is it the case that all observers would agree on the number of oscillations of the de Broglie wave across the spacetime interval traversed by the muon or is this observer-dependent?

    B Time Dilation & Muon De Broglie Wavelength: Explained

    I understand it's experimentally verified muons traveling at relativistic speeds relative to an observer will be observed to have longer half-life than would be observed in the rest frame of the muons, which is explained theoretically by a relativistic time dilation effect. Does this correspond...

    Extracting carbohydrates from food dissolved in hydrochloric acid

    If I understand correctly the concentration in the stomach is ~0.16 M/L, but also I'm not necessarily intending for kids to actually work with the acid, just to show

    Extracting carbohydrates from food dissolved in hydrochloric acid

    I know that food is dissolved in hydrochloric acid in the stomach, and carbohydrates are eventually extracted for use in cellular respiration which if I understand correctly is essentially a complex combustion reaction, using oxygen and releasing CO2. Outside the stomach, I can partially...

    When do you know you have understood physics?

    I'm surprised that none of the options was "When your understanding matches experiment"

    How does the free market prevent monopolies?

    I'm not exactly a market fundamentalist but the question as phrased seems a bit odd to me. "free market" is maybe too vague of a concept in general but I think the primary feature that I'd assume everyone could generally agree on is that "what it does" is largely determined by the free (albeit...

    B Does gas expanding in a container cause displacement of the container?

    Thank you all for the responses. So is the damping of the oscillation entirely due to the viscous stresses? i.e. without viscous stresses would the oscillations continue indefinitely?

    B Does gas expanding in a container cause displacement of the container?

    A couple more questions: would the container be expected to oscillate around the center of mass in a predictable way? i.e. if the removal of the barrier causes the container to undergo a large acceleration in the direction opposite to the expansion, will the particles colliding with the far wall...

    B Does gas expanding in a container cause displacement of the container?

    Regarding the collision theory, I think that makes sense informally Regarding the observer comoving with the container I guess I mean how does that observer account for the force that causes the movement No looks like the same scenario to me I see, thanks, I didn't account for whether the...

    B Does gas expanding in a container cause displacement of the container?

    If particles are trapped in one half of a massless container by a barrier, and the barrier is removed so that the particles are allowed to expand to fill the whole container, it seems the center of mass would be displaced to the center of the container, whereas before it was located at the...

    B Waste-to-energy question (not homework)

    Is this equivalent to the question of whether the trash material can sustain its own combustion without further energy input?
