Nugatory's latest activity
-
Nugatory reacted to Dale's post in the thread I About the notion of non-standard inertial frame with
Like.
I think that the term “inertial frame” means what the author using the term defines it to mean. There are variations in the literature. -
Nugatory replied to the thread B Opposite law propose.There's not much point in proposing a greek letter for us in describing multiverses when the multiverse notion is an idle speculation...
-
Nugatory reacted to Dale's post in the thread B Why would an atmosphere without greenhouse gasses be colder than with them? with Like.
With GHG in the atmosphere the surface of the earth is in radiative “contact” with a reservoir that is at the temperature of the...
-
Just think about that for a minute. You are standing by the road and a passing car turns on its turn indicator. How are you and the...
-
Maybe it would help to imagine two flash bulbs, one in motion relative to the other. They both flash when one just passes the other. In...

Nugatory replied to the thread B Train Fall Paradox.Most relativity "paradoxes" are better described as "apparent contradiction resulting from a hidden bogus assumption, often used as a...
-
Nugatory replied to the thread Is this device possible (hope not)?.Sure, if you assume the simuulation hypothesis then anything is possible; the master software developer just has to hack together a few...
-
Nugatory replied to the thread Physics Career Prospects (outside of academia).With tongue somewhat in cheek, I've said that I used my undergraduate physics degree the way that a male peacock uses its tail feathers...
-
Nugatory reacted to Cthugha's post in the thread I Importance of Hanbury Brown and Twiss experiment with Like.
Michelson interferometers, Mach-Zehnder interferometers (and also the double slit) measure field correlations. The quantity you measure...
-
Nugatory replied to the thread I Prof Mike Wiest's proposed link between quantum and consciousness.It is not impossible that more years (decades?) of AI development will lead to conscious physical systems In which the underlying...
-
Nugatory replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.If it is at rest in the center of mass frame and we have arranged for a fully inelastic collision to happen inside it?
-
Nugatory replied to the thread I An invariant while crossing the horizon.This is tricky even without introducing the complexities of an evaporating black hole. "Crosses the horizon at a finite proper time...
-
Nugatory replied to the thread I I don't see how a black hole's event horizon can be crossed.This is a false dichotomy. For purposes of constructive discussion of special relativity, forty or so hours with Taylor and Wheeler’s...

Nugatory replied to the thread I I don't see how a black hole's event horizon can be crossed.The equivalence principle says that sitting in a box at rest on the surface of a gravitating body (for example, in a closed room on the...
