Aside from a couple of holdouts (Uncle Al to name one, heh heh), the crusade to
ignore the worst trolls seems to be going well... I'm posting this to see if
I can add anyone else to the list of contributers who choose not to bang their
heads against the titanium barricades which ...

You need a force stronger than gravity to inflate the universe.
The orginal gravity of the universe must have therefore been a finite
quantity since only a finite gravity can be overcome by inflation.
The only way for gravity to be finite is for matter to have a

Is it true that fast moving water can exert pressure of up to four times its
speed against the legs of someone attempting to cross it, and if so why?

Given ... needs a brain. Wouldn't uncle Al be wiser on his position ?
Given ... needs a heart. Wouldn't uncle Al be more sensible than he?
For my feeling, uncle Al just needs the opportunity to display his charm.
A prudent king has all power but no choice. Take your chance ...

    My dad told me that Neon tubes became more efficient when they
switched from DC to radio frequency AC to power them. Anybody know _why_
this would be? Is the exact radio frequency used an even division of one
of the frequencies in the emission spectrum?

Hi, I'm a little confused about a one-dimensional heat equation
problem.  If anybody can guide me in the right direction I'd
appreciate it a lot.  Thanks!
We start with the heat equation

Follow my math and correct me if I am wrong.  This sounds too amazing
to be true.
The gravitational constant (G) is 6.6742E-11m^3/(kg s^2).  The mass of
the earth (M) is 5.9736E+24kg.

"The Einstein Hoax "
    "The Einstein Hoax" is intended for those who have been suspicious of the
premise that reality is so subtle that it can only be understood in terms of
sophisticated abstract mathematics to which only the elite was privy. The

i have started reading landau's course in theoratical physics and came
across hamilton's principle.in short it says that every mechanical
system has a function associated with it whose integral should be
minimum in any mechanical process with given initial conditions.

maybe any of you helps how to name it in english then I can use search
engines for more detailed information, working principles etc.
Unfortunately english is not my basic language, so I have to describe it
shortly.

If Bush stays in power maybe they'll just attack the whitehouse,
pentagon & bush supporting cities, and leave everyone else alone.
A vote for the bush regime is a vote for the most extremely idiotic
administration in the white house, that i've ever seen. It would be a

I am looking for a miniature vacuum pump that can pull about
-4 in Hg in a volume of about 1 in^2.  The pump also has to reside in
this volume.  The smaller the pump the better.
Can you please recommend some places to look for existing products or

Few things seem so self evident for us in our everyday's life as rigid
bodies. Indeed, one could argue that our visual perception is based
upon rigid bodies and the changes in their projected images at the
retiona, when they move.
