Nugatory's latest activity
-
Nugatory replied to the thread Vector/Phasor Addition.I'm not seeing what you're trying to do here. What are these ##X_i## quantities and where did they come from in your example? -
Nugatory reacted to PeterDonis's post in the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”? with
Like.
We already know Nature violates some premise of the Bell proof, because Nature violates the Bell inequalities. -
Nugatory replied to the thread I Wigner's friend and quantum tunneling.But it can, as long as the wave function has non-zero amplitude outside the box. Two consecutive position measurements will in general...
-
Nugatory replied to the thread B Simple mass/scale puzzle.I agree, but I find that the free body diagram of the two components of the scale (hook attached to the pointer, case) is how to do that.
-
Nugatory replied to the thread I Shape of wave function (probability distribution) of a single photon.It isn't. We explain the double-slit experiment with light by doing a classical calculation of classical electromagnetic waves passing...

Nugatory replied to the thread B Simple mass/scale puzzle.You can try a free body diagram that includes as separate components the hook on the scale and the case of the scale. The hook is...

Nugatory replied to the thread I Shape of wave function (probability distribution) of a single photon.You could, and then you would indeed get a wave function as an answer. If the process creating the electron allows the electron to be...

Nugatory reacted to div_grad's post in the thread I Phase and group velocity for the wave function with Like.
@hokhani Note that this issue of group velocity of a wave packet can be equally well formulated in, e.g., classical electromagnetism...

Nugatory replied to the thread B Conflict between the conservation of matter and the rapid expansion of our universe.A digression that was unhelpful to the thread and served only to make unnecessary work for the forum moderators has been removed. All...

Nugatory replied to the thread I Question about a Square Light Clock.Speed relative to what? Imagine two of these light clocks, identically constructed and moving relative to one another. Both will find...

I am also a retired college math teacher (over 40 years teaching). So I am on the side of Mark44 in this matter. I do not disagree...
-
Nugatory replied to the thread B Flatlander analogy of spherical surface as observable universe.You are basically right about what is meant by "observable universe", and also that the word "observable" is often left out. But I am...
-
Nugatory replied to the thread B How does the Riemann Hypothesis/Riemann Zeta function even work?.But do you want an answer that makes sense at the graduate level, or that makes sense to a high schooler with the math background that...

Nugatory replied to the thread Trying not to ruin what I edit.The only way I ever edit.

You can always switch to the BBCODE editor for any fine tuning. Thats what I do, especially when nesting quotes.
