many people have the misconception that quantum nature is random
what the uncertainty principle states is that facets of quantum nature,
location and momentum, cannot be known at the same time
this means we are uncertain and will always be uncertain about quantum

Stanford Universities Nobel prizewinner, Robert Laughlin, has produced a
treatase about 1/3 e as a charge.
When I was a physics student at Portsmouth University in about 1968 we did
the students version of millikin, the oil drop experiment. I found there was

"Overview of the Einsteinhoax Website"
    The Einsteinhoax Website was setup to counter an intellectual "fast
shuffle" which used Dr. Einstein's Special Relativity (which is easily seen
to be a mathematical copy of the earlier Lorentz Transformations Aether

I was just wondering if anyone here could give me a rough estimate of
the number of particles that were confirmed after having been
hypothesized. Even just a guestimate, like "a large number, "a
moderate number, "a small number." "hardly any," etc. would do just

Thank you in advance for your time. I found a neat project to do with
my 14 year old son, but would like to know the science behind it so it
will be educational.
Here is the video link.

"Are Unified Field Theories Justified?"
    Modern physics seems to be searching for ways to incorporate all
physical phenomena into a single unified theory. The question that comes to
mind is why? The question arises as to the conceptual need for such an

I wondered if this was interesting to readers of this group:
http://overinflation.org/.  Overinflation.org is a particle phsyics
news site written by active researchers in the field. It provides an
insiders look at the world of experimental particle physics.  Please

It was said in one reference, that except for higgs boson, 61 in 62
elementary particles predicted by Standard Model has been supported or
discovered experimentaly.
what is the 62 elementary particles?

"The Brilliance of Our Teachers"
    A recent newspaper question and answer column raised an interesting
subject. The query noted that, for a science course at a local school, there
were two instructors. One of those instructors explained the concepts

I am writing a paper on Windows using WinEdt and i need to include
some feynman diagrams
Anybody knows of any free software one can use easily to make feynman
diagrams ?

I am trying to understand the following statement on photoelectric
effect:
"When light shines on a metal, electrons are emitted. However,
electrons are emitted only at specifc threshold frequency."
