| An accelerometer in free fall measures zero force.

Right. So the command module and occupants are accelerating toward
Earth by a = dx2/dt2 and F/M is irrelevant, the forcemeter reads zero.
Fucking simple, nothing to argue over or debate. It's fact.
Lay flat on you back in bed at home, the forcemeter reads positive in
the z-axis, 0 in the x- and y-axes (and they do, I've worked with them)
you are not accelerating up or down or you'd go through the roof or
floor. Fucking simple, nothing to argue over or debate. It's fact.
An inertial guidance system on a plane (and I've worked on them)
integrates (yes, analogue computers integrate) the signal from the
forcemeter divided by the calculated mass of the plane as fuel
is depleted to give the velocity, that is then integrated to give x,y and z,
the plane knows where it is relative to its start point.

It's not quite that simple, winds can affect the calculation and the pitot
tube
http://www.grc.nasa.gov/WWW/K-12/airplane/pitot.html
is used also.
The lunar excursion command capsule hasn't got a fucking clue
where it is using aircraft technology. Today, of course, GPS is used,
but military planes are still equipped with INS because in the event
of a nuclear holocaust with the former USSR the western world
anticipates the GPS will be destroyed, Oz and Europe do not have
a backup GPS yet and Britain quit rocketry at Woomera a long time
ago, too expensive, our women need cosmetics to look good and tattoos
are in vogue yet again.

C'mon... this *** is so basic and obvious, Einstein was just a dickhead.

Ok, so the runway moves under the plane. That kinda fucks up F= ma,
it takes a lot of force to accelerate the Earth. Actually force is relative
too,
we intuitively assume the Earth is at rest but it isn't. When a rocket
leaves Earth the Earth's orbit changes, but the change is too small
to measure.

This what I'm looking for:

It's got TWO curves at the bottom of the loop.


I thought you really had it, you came fucking close with
http://www.androcles01.pwp.blueyonder.co.uk/rrlyr2.jpg
but then you went off on a tangent about Wilson Cool Heavies
or some such *** to boost your stupid fucking ego, got into a
waste of time argument with that stupid *** Andersen and that arsehole
Dishwater and the whole thing petered out to nothing. Here you are,
jaw-jaw about how fucking right you think you are and refuse any help,
prattling over Newton's laws like a 13-year-old.
What you don't realise is that if you do this right you can make a
serious contribution to physics and astronomy, but as things are you
look like a fuckin' crackpot aetherialist.
That's the FUCKIN' DATA. Model it properly, the star is beyond
critical distance, you fuckin' deadbeat. You are a fuckin' joke, Wilson,
you've have six years in that program and got nowhere past an ordinary
cepheid.

I can see these from where I live:
http://www.yes2wind.com/nonflash_details.php?Region=South+Coast&SiteId=470
and I like 'em, offshore, silent, little environmental impact, no smoke, no
radiation.
Welsh mountains are covered with them.
Why wind?
http://www.yes2wind.com/whywind.html
I'm no Greenpeace fanatic, but wind, wave, hydroelectric makes sense.
Where you are, sunlight. All your energy needs for your house falls on its
roof,
add a battery for night time use, charge in daylight and you are all set.
Same with
your car. *** the uranium, *** the oil, *** the gas, leave it all in the
ground.
Chernobyl was pretty bad.
