Question about how steel beams fail30 Jul 2008 23:09 GMT1
Suppose you were pounding a steel beam into the ground with a pile driver.
After you had driven the
beam say five feet into the ground, you then arranged to hit the top of the
beam with a weight far heavier
Big Bang Energy Buildup30 Jul 2008 22:24 GMT3
The Dark Energy of the universe started at zero and built up. It was
then concentrated into neutrons on the inflated hypersphere surface of
which also started at zero or time zero. These neutrons decayed into
protons neutrons neutrinos and incidental radiation that we now call
361 clocks vs 1 moving clock30 Jul 2008 21:47 GMT62
Lets have fun as usual with clocks.
We take 360 clocks and set them up on a level circlular
platform.
The circle is 1 mile in circumferance.
Magnetically Coupled Resonance30 Jul 2008 20:43 GMT17
I was reading about magnetically coupled resonance recently, and a
question came to me. How is MCR any different than a radio transmitter
and receiver?
Gyroscope30 Jul 2008 20:41 GMT13
In a famous experiment in the Christmas lectures in London Prof Eric
Laithwaite had a small boy lift a huge gyroscope when not spinning.
the boy could hardly lift it. He then set it spinning and the boy
could lift it easily. Now when you push on a gyro it precesses and
Space's Time30 Jul 2008 20:03 GMT4
Two times: one for space(gravity) the other for matter in that space.
Space's time pushes light. Matter's time is always slower than space's
time becuase it moves and there is the transverse Doppler.

Rainbows only exist on Earth30 Jul 2008 19:36 GMT53
To see a rainbow a person must be in the right position for light of
specified wavelengths to enter the eye at certain angles.
On planets where humans do not exist there are no eyes and no color
vision to percieve the phenomenon of a curved multi-colored arc in the
New Technology for Energy Independence...30 Jul 2008 19:15 GMT3
What with the high price of gasoline and the energy crisis, clearly
new technology is needed to save the planet. Luckily many smart people
are thinking about these problems and have developed new technology to
save the earth. One example is seen below:
Does Relativity generate more heat than light?30 Jul 2008 17:36 GMT123
I suggest that if anyone wants to analysis
the utility of the various physical models,
that they take a look around and note what models
are used every day to make life better for mankind.
Where is Now?30 Jul 2008 17:26 GMT22
It is out there in the rest of the universe simultaneously. Space time
tells us Now is everywhere. The past no longer exists and the future
doesn' exist yet but will.

Twin Fallacy revisited30 Jul 2008 14:14 GMT59
The twin paradox has been analyzed many times, and many answers ar
given.  Dr. Parker has pointed to the multiplicity of the answers a
proof of its underlying error.
The standard answer brings in a new set of rules.  While the paradox i
South Dakota has 500,000 MW wind energy potential30 Jul 2008 12:23 GMT61
    This is more than 4 times what India produces in total
electricity at the moment or half what the USA does  , and wind energy
can be set up within two years

Which is the strongest structure : Honeycomb or Arch?30 Jul 2008 09:09 GMT22
Strongest structure for say a bridge where the force is mostly
downwards.
I've heard the honeycomb is the strongest structure in nature.  Bees
have evolved to use it over millions of years when building their
Acceleration slows time30 Jul 2008 09:08 GMT66
HIgh speed inertia keeps time slow.
Acceleration decelerates time.
