Roberto Pavani's latest activity
-
Roberto Pavani replied to the thread Undergrad Ampère's mercury experiment and Aharonov-Bohm: same message?.The symmetry I refer to: current approaches the bar through one trough and leaves through the other, in opposite directions. These two... -
Roberto Pavani posted the thread Undergrad Ampère's mercury experiment and Aharonov-Bohm: same message? in Classical Physics.I'd like to share an observation and ask if others find it compelling. Consider a current-carrying loop that tends to expand. This...

Roberto Pavani reacted to Baluncore's post in the thread High School Another dumb SocMed quiz with
Like.
Apparently birds warm their feet on bare wires. Maybe their bodies are actually being dielectrically heated by the AC field near the... -
Roberto Pavani replied to the thread High School Another dumb SocMed quiz.The effect is very different between DC and AC current. With DC, if you hang with both hands, the scenario is similar to...

Roberto Pavani replied to the thread Undergrad The effect of a radio wave on an electron.Just a small note: the TV signal mentioned is DC-coupled at baseband, the asymmetry exists only because there's a ground reference. Once...
-
Roberto Pavani replied to the thread Undergrad The effect of a radio wave on an electron.As others have noted, the drift direction is phase-dependent, so it's really an artifact of the initial conditions rather than a general...

Roberto Pavani reacted to sophiecentaur's post in the thread Undergrad The effect of a radio wave on an electron with Like.
The printed passage starts by mentioning the Ionosphere so it's not really an idealised situation unless it's a sinusoidal wave. In the...

Roberto Pavani reacted to tech99's post in the thread Undergrad The effect of a radio wave on an electron with Like.
-
Roberto Pavani reacted to Peter Morgan's post in the thread A question about quantum entanglement with Like.
Classical measurement theory in the presence of thermal noise can and should include contextuality as noncommutativity, because it's a...

Roberto Pavani replied to the thread Undergrad Why ##a^0=1##?.x=:doh:= 42
-
This is getting to be a very boring thread. It's as if someone thinks it could be possible to prove this stuff actually wrong!
-
Roberto Pavani reacted to Matterwave's post in the thread High School The problem of energy appearing out of nowhere with Like.
Note that in non of my discussion w/Peter did either of us try to find the "energy momentum tensor of the gravitational field". We were...

Roberto Pavani replied to the thread High School The problem of energy appearing out of nowhere.Very interesting discussion. I'd note that the arXiv preprint I referenced in a related thread (Hobson, Barker & Lasenby...
-
Roberto Pavani replied to the thread A question about quantum entanglement.Perhaps worth noting: the "information" that cannot travel FTL is not just the measurement outcome, it's the outcome plus its spacetime...

Roberto Pavani replied to the thread Graduate Is Energy conservation among sectors (EM,GR,QM) a principle?.I came across a recent arXiv preprint that seems relevant to this discussion: Hobson, Barker & Lasenby (arXiv:2605.19719, May 2026) show...
