what is "local causality" in phisycs?

Every effect has a cause is one of the scentral guiding principles of Science. In physics, local causality refers to the effect demonstrated in the immediate neighourhood of the causing force

Hmm.... I can't seem to find one on the sites I've checked, but based on inference, I would guess it would be something like Argmt. or Agmt. These aren't official, mind you, but with a little hard work they could be ;) .

It might help if you specified where "local" was!

They might be in the paper "Inequalities for $&#92;sigma (n)$ and $&#92;varphi (n)$".  It was published in Mathematics Magazine volume 45 in 1972.  The Journal was also called Delta previously, so it might have been under this name at the time of publication.

Something involving atomic spectra.  For example see\nhttp://www.fas.harvard.edu/~scdiroff/lds/QuantumRelativity/StreetLampSpectra/StreetLampSpectra.html

The algebraic sum of the currents entering a node is equal to zero. Where current entering is positive and exiting is negative (or vice versa). In other words, what comes in must come out.\nNote: this is only true for DC signals.

I never thought about it but thank you for the idea. Now that i think i bet it most likely is. It would make sense because it is describing what happens in the area around you... thx !

The central limit theorem still applies.\n\nWhen variables are correlated a principal component analysis will find the independent variables for which the CLT applies.

Given enough imagination, you can explain almost anything with a sufficiently large dataset to draw on: see Slutzsky's Theorem and think about it in terms of things outside time series analysis...\n\nHaving said THAT, the theory has been advanced that these sightings actually could fall into numerous types of categories; some are quite probably purely psychological phenomona, others are probably illusions or misperceptions; some may well be a cockeyed chain of events that are (individually) quite mundane but which are bizarre as a chain--field effects and the like.\n\nWhat I have heard suggested by serious, rather free-thinking but otherwise hard-nosed physicists is that there may be the temporal equivalent of a wormhole: something that will transmit light across large spans of time, but little else, other than (perhaps) other fields and possibly pressure waves (=sound).  Do I buy that?  No--nor do I reject it out of hand, either.  HOWEVER, it is interesting to note that spectral appearances are invariably from the past, and often from the distant (but not too distant) past.  We're talking years to a few centuries, rarely if ever millenia, and I've never heard of a ghost CroMagnon or Astralopithicus or even Homo erectus or whatever.  This suggests that there is a distancing issue--you can only jump so far forward, so to speak, or the perception can only be so long delayed.\n\nThis thought is potentially one that is experimentally testable, actually--or at least potentially so.  Consider this thought: if there is something equivalent to a wormhole or quantum tunneling through time, it is reasonable to assume that the larger the distance in time "traveled" the more blurred the image is likely to be.  THUS, you can set up a "grid" of observations that allow you to rate how "clear" an apparation is--things like number of facial features clearly present, whether clothing is present, whether audible and discrete phonemes are heard in any sound made (you might want to go for just consonants; they's likely be disappearing before vowels, and that gets you past most barriers caused by languages differing); and you can set up some sort of tool (how, I don't know) to allow you to rate the probable age of the appearance.  That would probably need some sort of something to identify the period of the spectre--like period clothing, perhaps, which would require a fairly clear apparition, or the legend of who the spectre is supposed to be, and from when--but I leave that detail to you, because you've probably more data to sift and can find more in terms of datable stuff than I can dredge up out of my ol' brain.\n\nThe null hypothesis: there is no relationship between clarity of apparition and putative age of its source.\n\nActive hypothesis: the older the putative age of an apparition's source, the less distinct it is likely to be.\n\n\n\nJust remember: don't expect a single explanation to handle it all, because the odds are that there are multiple phenomona all being lumped together as "ghosts" or "hauntings"...

I hate to admit it, but only one of these theories existed when I was in school.  SHMO is in the realm of computer assisted quantum chemistry that has sprung up in the last few decades.  I'm too old of a dog for this level of stuff anymore.\n\nPlease accept my apologies!
