Meter General Research

What is Your opinon on EMF(Electromagnetic Field) Meters and What are your beliefs of High EMF Readings?
Just a curious paranormal researcher getting the general public's Theories?
and what is your guys opinon on why ghosts exist how about this one if you can't answer the others what is the most common paranormal activity (Not just ghosts) takes place in a location claimed to be haunted ? Thoughts?

Hi,
According to what I've read from various ghost hunter outfits, EMF is often used at least a couple ways: (1) fluctuations in EMF are taken as evidence of ghost activity; and (2) high EMF is chalked up as a possible cause for hallucination. It seems to depend on how credulous the ghost hunting team is, but both concepts are very common if the various ghost hunting websites are any indication.
There is some amount of evidence that (2) is a possibility. Electromagnetic fields have been used to induce hallucinations and changes in mood or feeling. Interestingly enough, EMF has also been used to eliminate hallucinations! (See Yale link).
As far as (1), I have to agree with AlBro that there is no mechanism supported by scientific theory that would predict fluctuations in EMF due to spirit activity, let alone that spirits even exist. As far as can be determined, EMF detectors are only indicators of EMF and nothing more. So using the EMF in this mode really is a matter of individual belief.
You may not be aware of the this web site, but ASSAP seems to be one of the better pro-paranormal websites out there which doesn't fall into a lot of the pseudoscience traps. Check it out. I certainly don't agree with all of it, but it's far better than most. It does have a lot to say about EMF which I'm sure you'll find interesting. Interestingly enough, they assert that EMF meters are actually a poor tool for detecting the kind of magnetic fields which lead to psychological effects.

Society for General Systems Research $71.7 High Quality Content by WIKIPEDIA articles The Society for General Systems Research (SGSR) is predecessor of the current International Society for the Systems Sciences (ISSS), known to be one the first interdisciplinary and international cooperations in the field of systems theory and systems science. This organization was initiated in 1954 as Society for the Advancement of General Systems Theory, got formally underway as Society for General Systems Research and was eventually renamed in 1988.

Light Meter $95.59 A light meter is a device used to measure the amount of light. In photography, a light meter is often used to determine the proper exposure for a photograph. Typically a light meter will include a computer, either digital or analogue, which allows the photographer to determine which shutter speed and fnumber should be selected for an optimum exposure, given a certain lighting situation and film speed. Light meters are also used in the fields of cinematography and scenic design, in order to determine the optimum light level for a scene. They are used in the general field of lighting, where they can help to reduce the amount of waste light used in the home, light pollution outdoors, and plant growing to ensure proper light levels.

Medical Research $184.81 High Quality Content by WIKIPEDIA articles Biomedical research or experimental medicine, in general simply known as medical research, is the basic research, applied research, or translational research conducted to aid and support the body of knowledge in the field of medicine. Medical research can be divided into two general categories: the evaluation of new treatments for both safety and efficacy in what are termed clinical trials, and all other research that contributes to the development of new treatments. The latter is termed preclinical research if its goal is specifically to elaborate knowledge for the development of new therapeutic strategies. A new paradigm to biomedical research is being termed translational research, which focuses on iterative feedback loops between the basic and clinical research domains to accelerate knowledge translation from the bedside to the bench, and back again.

Noisetube: citizen noise pollution monitoring using mobile phones
What IS acceleration (besides a confusing concept) and a Newton / Joule?
Well, I've researched my textbooks and wikipedia.
I think I may know the general idea of what it is, but I want to be sure.
This is what I think....
-So I read that Acceleration is the rate of change, and a Newton is the force required to accelerate 1 kg of a substance by 1 meter per second squared (1 kg * m / s2).
So if I have my meaning of Acceleration correct, then if something had an acceleration of 5 Newtons, then for every second passed, 1 kg of that substance would speed up 5 meters per second more? So if it starts out at 10 m/s, then in 3 seconds it would be going at a speed of 25 m/s? Is that right?
And I know that a Joule is "the energy expended by a force of one newton moving an object one meter along the direction of the force." but can someone explain that to me more?
So...if a block of concrete that weighed 1 kg was sliding down a hill with a force of one newton (meaning it sped up 1 meter more per second?) then for every meter it slid, that would be 1 Joule?
Hmm...Acceleration (from here on "a") is the rate of change of velocity (from here on "v"). So in other words, how many meters per second an object goes faster per second. The unit of a becomes then: meters/second² ("m/s²"). So in your problem you would have an "a" of 5"m/s²" and not 5Newton.
Newton is indeed the unit of force. And any force (you know the drill "F") is defined by the formula: F= mass ("m" m not being meters, but mass and thus in units of kg) *acceleration = "m"*"a".
Your first derivation is correct despite the incorrect use of units.
Joule is the unit of Work ("W"), work is defined as you said. This gives the formula (for a straight line that is) "W"="F"*"distance traveled". For an inclination (a hill of some sort) this becomes much more complicated, because the force acting on it isn't parallel to its distance travelled.
So lets say, you have a concrete block of 1kg which you pull forward with a force of 30 Newton along a path of 12 meters. The formula yields:
"W"=30Newton * 12metres = 360 Joules. So indeed, if you pull the same block with a force of 1 newton during 1 meter you get 1 Joule.
I hope this clarifies things a bit, just be carefull with those units, teachers can be picky on those
