Nugatory replied to the thread High School How a local interaction coordinate response of atom.You are describing non-relativistic quantum mechanics, the only kind you’ll encounter unless and until you’re well on the way to an... -
Nugatory replied to the thread Undergrad Bell's theorem and measurements not done.For the sake of the analogy, we're assuming that the couples have been preselected to meet the conditions that every couple consists of...

Nugatory replied to the thread Undergrad Are annulled gravitational fields detectable?.Native speaker here, agrees with your edit. A gauge produces measurements, a guide points out a path to a conclusion or destination.

Nugatory replied to the thread Undergrad Are annulled gravitational fields detectable?.Your intuition is mistaken here. Away from the edge effects and if the two slabs are identical the field is zero. That’s just another...

Nugatory replied to the thread Undergrad Problem in understanding how upwards acceleration works (General Relativity).Goethe (actually not Goethe, that’s a loose paraphrase from an English language translation) has a good point but you’ve misunderstood...
-
Nugatory replied to the thread Graduate How many interpretations of QM do you speak?.There remains the (rather discouraging) possibility that there is no natural interpretation.
-
Nugatory replied to the thread High School Why is g = 9.8 and from where/what triggers the upward acceleration?.There is no such thing as "real acceleration", at least until you provide a definition of this non-standard term. There is proper...

Nugatory reacted to Roberto Pavani's post in the thread High School Why is g = 9.8 and from where/what triggers the upward acceleration? with
Like.
Fair enough, I missed a comma. “We have an upward proper acceleration, with ‘upward’ defined relative to a local freely-falling frame.” -
Nugatory reacted to Dale's post in the thread High School Why is g = 9.8 and from where/what triggers the upward acceleration? with Like.
Proper acceleration is not relative. We have an upward proper acceleration. Full stop. Relative to a local freely-falling frame we also...

Nugatory replied to the thread Graduate Measurement of mass geometrically.It's four-dimensional spacetime that is curved, and it is far easier to measure the effects of curvature in the time direction than in...

Nugatory replied to the thread Undergrad Query on use of prism in delayed choice quantum eraser experiment.It's not "light", it's single photons and .7 mm is four orders of magnitude more than the 350 nm wavelength of the photons. They can...

Nugatory reacted to Herman Trivilino's post in the thread High School Einstein equations don't work at large scale? with Like.
The value is 9.80665 m/s². It came into existence when the now out-dated unit kilogram-force was defined. It's a relic. There is in...

Nugatory replied to the thread Undergrad A deep discrepancy between the classical and quantum models of ##L##.Nothing. When QM allows something that is classically forbidden, the explanation is that it isn't really forbidden and the classical...

If you build two concentric rings of different sizes around a spherical non-rotating mass ##M## and measure their circumferences ##C_1##...

Nugatory replied to the thread High School Randomness in quantum mechanics.Could be…. And if so would be aesthetically satisfying for many, it’s a major impetus behind consideration of hidden variable theories...
