  let me take the simplest covalent bond i.e in H_2^+ (basically two
hydrogen nuclei..i.e protons, bonded via a single electron).
Here one can see why there sould be energy stabilization...the electron
instead of being bound to a single proton is now delocalized between two

   I am  a second year physics major, and have just dipped my toes into the
realm of particle physics. Its a very interesting field, but I was left
unsatisfied after the class i took ended. It seems that there is a great
deal of fuss made in physics about symmetry, especially as ...

Can someone explain to a layman (me) how Quantum Entanglement occurs?
So far what I've heard about it is that two particles (beit two
photons or two electrons or something) are somehow connected together
and synchronized in their spin states -- or actually

I am French and would like to present you with a new high-performance
heat pump process using a micro-electronic manufacturing process.
Besides the traditional heat pump use, this process would allow for a
system of electrical production by cooling the environment. Be

How does the sigma-0 and lambda particles differ?  According to the
tables of particles, they have the same quarks (uds), same spin, same
baryon number, same everything.  A sigma is heavier and will decay into
the lambda and a gamma.  What happens internally (what do the quarks

The classical EM equation for conservation of charge is
div J + @\rho/@t = 0
where J is the current density, @/@t is the partial derivative with
respect to t, and \rho is the charge density.

Where Is The Kinetic Energy of a Bullet Stored?
    When a bullet is fired, an explosive charge imparts kinetic energy to the
bullet. That kinetic energy travels with the bullet and is transferred to the
target when the bullet strikes. The question to be answered is where that

Sometimes even physicists  do not realize the difference between
Data extrapolation and  '*physical understanding extrapolation*
And the weigh of importance that has to be related to the two different cases
Let me try and give some example just off hand to explain what I mean

    MODES OF THOUGHT
    The primary question then becomes - what is thought and what
does it provide us in measurable terms?
    Imagine a fictitious animal that can survive but is incapable

Here's an interesting article:

This is a rare example of the electronic world influencing the nuclear
world.

Please excuse my complete and utter ignorance when it comes to this
subject but I really am only starting to learn about Quantum
mechanics, and even then only on a recreational-paper-back level.
I thought I would come to the guys who actually study it and ask them

Suppose you have a simple  electroscope charged with electrons so that the
leaves diverge.
My  understanding is that the explanation for the forces is this :
By the uncertainty principle, mass/energy multipied by time is constant, so

I'm looking for a book (paper or electronic) or document that shows
entirely the proof of the Planck radiation law with all mathematics
developements (the document can be in french, english or german).
Thanks for yours advices

I would like to propose for discussion, in a purely conceptual way, a
possible alternative to the currently "accepted" theories of Quantum
entanglement.  First let me say, I am not a physicists, I spend my
time programming computers.  That being said, I ran a across a few

Hi,simpel question is anyone can help me:
Is the decay rate of positive muons different for "stopped" positive
muons (as in stopped in a scintillator) and free positive muons?
Thanks.
