I have a simple minded theory of elementary particles that people may be
interested in.
String theory started as a simple way of modelling the characteristics of
elementary particles as the result wave movement on a tiny circular string

Can any1 help me this one. I ahve been trying grabbing it, but, i
couldn't. So, plz help me doing that.

"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

"The Right Angle Lever Paradox"
    The "Right Angle Lever Paradox is a classic construct which is taught
in most courses in Special Relativity. As with all paradoxes, it reveals
that and error has been made in our thinking. It may be interesting then to

Are there still poor souls out there who believe that the photon is
massless?
If so, come into the 21st century and recognize that the photon has
mass.

My physics book uses the expression;
psi(x) = A exp(ikx) + B exp (-ikx)
to model the incident and reflected components of  a steady state beam of
particles of well defined momentum as they scatter normally from a surface.

"Is There a Force of Gravity?"
    In undergraduate physics, the Newtonian concept of an attractive force
between masses that is proportional to the product of the masses divided by
the square of their separation is taught. When one advances to the more

I'm really hoping someone out there can help me, I've checked the web my
textbooks and I can't seem to figure this out. When it comes to a sampling
calorimeter we get resolutions of the form
