In science, what are diverging lenses used for? I know some
applications of converging lenses, but none really of diverging
lenses.
Are diverging and converging lenses often used together in one

Yes, it's for geeks only, geeks dominated by mighty barbarians like me
who force the geeks to do what we want !

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

                       GLOBAL EMERGENCY ON PLANET EARTH!
            The human race is being systematically  exterminated by a
race of malevolent alien beings that possess a remarkably human
appearance.  This human(hybrid) alien race has been  living amongst the

I never met in physics books a look upon the Pauli principle as a kind
of interaction between 1/2-spin particles. Can anyone answer is such a
consideration possible and if not why?

I have no idea and can't find out what the optical band gap is

Has anyone here seen this move?  ("what the bleep do we know?")  I'm
wondering what you guys think about it.  I was appalled to see such
misrepresentation of science and was even more appalled afterwards to
find very little negative information about the movie on the web.  It

Nobel Prizes boost U.S. science
Americans have captured or shared in all three 2004 Nobel Prizes
awarded in scientific fields, a result that seems to contradict
complaints of declines in U.S. scientific research and science

One of the main techniques used by the Communist ANC to discipline
anyone that opposed them is called "necklacing." In case you don't
know what necklacing is, I will describe it for you. Usually the
tendons are cut in the victim's arms and legs, so that he cannot flee

A Snapshot of a Photon    
     The photon has been viewed as a somewhat mysterious entity which
sometimes has the properties of a particle and sometimes has the properties oaf
a wave. It would seem interesting to see, therefore, whether we can determine

Here is a new, cool product being co-developed between NTT and Fujitsu Labs
in Japan: a FOMA (3G) phone recharger... apparently, Fujitsu found the right
formula for the mix:

Quantum fluctuations can also disrupt circuit performance. According

My question pertains specifically to classical mechanics.  I am
interested in Newton's principle of determinacy, which states that
specification of the initial coordinates and velocities of a particle
uniquely determines the state of the particle for all time.  Is this
