How do we weigh the earth ?
We use Newton's law that two masses attract each other with the force
equal to their masses multiplied and inversely proportional to the
distance squared between them .
Why should the force between them be proportional to inverse
squared and not inverses square of 2.5 or whatever is a great mystery
and something to do with the fabric of space which Uncle Al might know
about .
We can verify that the inverse square law is true by hanging
heavy masses in the lab and measuring how much they deflect a smaller
mass towards them . Nelkon's Scholarship Physics gives the details
From the force of deflections we can calculate G the gravitaional
constant to make the proportionality into an equal sign .
Now assuming all the mass of the earth M is at the center
where R is the radius of the earth , then its force of attraction on
a mass of m at the surface is MmG/Rsquared which we know is is equal
to mg , where g is gravity , and
So MmG/Rsquared=mg
m cancels out on each side , so M = grsquared /G
=5x10 exp 24 kg !!
mass of the earth M
Amazing how with a few simple experiments in the lab we can
calculate how much the earth and all the planets weigh !!
We can calculate the equatorial diameter of the earth by
measuring the angle which the sun makes at the Equator at noon - 90
with its angle say 200 miles farther on the same latitude . If its 86
degrees we know that the earth curves 4degree in 200miles or 1 degree
in 50 miles , so it must curve 180 degrees in 180x50 miles or 9000
miles , so its circumference must be 18000 miles etc.

It is not a "great mystery" to anyone that took high school physics.
Here's a grade school site that explains it; try reading it.

Having calculated the size of the earth , its easy to get the
distance to the moon . Take the angle of elevation above the horizon
from two points on the same latitude or longitude say moscow and
london and since we know the distance between the two , we cam
calculate since the angles of a triangle add to 180 . The Greek

One of the fascinating things about maths and science is their
relationship to the real world . For example caluclating the size of
the earth from common sense .
Here is the Habshi method . Assume the earth is a sphere . Now
since the center of the sun and the centre of the earth are in line
when the earth is upright and not tilted ie spring and autumn times
the sun must be overhead vertically at noon ie at an elevation of 90
degrees , at the Equator . Incidentally there is a town called Equator
near where I lived for a while (? which country is it in ) . At
noontime it follows that the sun over the North Pole will be on the
horizon ie elevation zero
Now you signal with lighs , so someone on the same longitude
100miles north and get them to measure how far the sun is below 90 ,
and another one another 100miles or so when it should be lower still .
These kind of repeat measurments are the essence of good science.
So say 400miles north you find the sun at noon is 6 degrees
below 90 . So in 400 miles it has lost 6 degrees . What will it lose
in 90 degrees ? . Obviously 400x 15= 6000 miles .
So the whole earth must be 6000 miles x 4= 24,000 miles .
Uncle Al please give me a pat on the back .
Also being directly overhead , on the equator the sun wont
cast a shadow on a vertical stick stuck in the ground , but 400 miles
to the north it will .A line drawn from the tip of this shadow to the
top of the stick gives the angle of elevation of the sun
How about the distance to the moon ?

Trouble is, the ancient Greeks did something like this thousands of years
ago. It was noted that on the summer solstice, there was no shadow in wells
in a particular town. Yet in a town some distance to the north, there was a
shadow in the wells. By noting the angle of the shadow (Greeks also loved
geometry), and the distance between the two towns, a pretty good estimate of
the earth's diameter was found.
Read some history/science books and find out what others have already done.
Then you wouldn't be 're-inventing' the wheel. Or in this case trying to
devise ways of doing things that have been known for thousands of years.

And by multiple methods. No doubt cartography was

but even U-2 flying planes could have presumably been
pressed into service for making pictures which formed
the basis for a drawn atlas.

Gee, isn't that what most people would call the definition of science
and math?

near where I lived for a while (? which country is it in ) . At
noontime it follows that the sun over the North Pole will be on the
horizon ie elevation zero
The Earth is allways tilted from perpendicular to the plane of the
ecliptic by about 23.5 degrees; it is never "upright".
At the vernal and autumnal equinox the tilt of the axis and a tangent
to the orbit lie in a plane orthogonal to the direction to the Sun.
This is high school stuff; did you sleep through it?
Now you signal with lighs , so someone on the same longitude
100miles north and get them to measure how far the sun is below 90 ,
and another one another 100miles or so when it should be lower still .
These kind of repeat measurments are the essence of good science.
Assume both observers are on equal height towers; how high must these
towers be to see each other from 100 miles away? Assume a smooth
Earth.
So say 400miles north you find the sun at noon is 6 degrees
below 90 . So in 400 miles it has lost 6 degrees . What will it lose
in 90 degrees ? . Obviously 400x 15= 6000 miles .
So the whole earth must be 6000 miles x 4= 24,000 miles .

Uncle Al would be more likely to beat you about the head and shoulders
with a blunt object.
Also being directly overhead , on the equator the sun wont
cast a shadow on a vertical stick stuck in the ground , but 400 miles
to the north it will .A line drawn from the tip of this shadow to the
top of the stick gives the angle of elevation of the sun

If you hold a child's arms and turn your body round fast , then the faster you turn , the
harder you have to hold on to the child until the outward force overcomes your muscle strength and
the child flies off . This outward force is called centrifugal and the muscle force which must
balance it inwards is called centripetal
The spinning earth also has a centrifugal force at the equator , but not at the poles which
are not turning . So a bit of earth is thrown out at the equator , enough so that its inward weight
balances this force ie the earth is like an egg , squashed from top to bottom , and bulging out at
the middle. The centifugal force is Mrwexp2 where w is the angular momentum related to the speed of
rotation and has to be balanced by mg where m is the mass of the earth displaced outwards . We can
calculate m and from the density of the earth , find that the earth bulges out about 10km at the
equtor .
Heavier bodies like Jupiter which are spinning fast are even more squashed and one can see
the sun and Jupiter are egg shaped while Venus and the Moon which spin very slowly are round.
What happens with neutron stars and black holes which are spinning at 60 times a second and
weigh as much as a billion suns ? They must be so squashed that they are actually disks !

Latest estimates are that the world will warm by an incredible
11C this century and its not likely stop there until it gets to
200C
.. Yanks and their big cars are to blame.
A major blow to the CO2-induced global warming hypothesis comes from
the instrumental
temperature record of the more recent past. This setback is manifested
in the contradiction between
observed and model-predicted Antarctic temperature trends of the past
three decades. According to
nearly all climate models, CO2-induced global warming should be most
evident in earth's Polar Regions;
but analyses of Antarctic near-surface and tropospheric air
temperatures tell a radically different story.
Antarctica. Comiso (2000) assembled and analyzed Antarctic temperature
data obtained from 21
surface stations and from infrared satellites operating since 1979.
They found that for all of
Antarctica, temperatures had declined by 0.08°C and 0.42°C per decade
respectively, when assessed
via these two data sets.
McMurdo Dry Valleys. Doran et al. (2002) examined temperature trends
in this area of Antarctica over
the period 1986 to 2000, reporting a phenomenal cooling rate of
approximately 0.7°C per decade.
This dramatic rate of cooling, they state, "reflects longer term
continental Antarctic cooling between
1966 and 2000," with the largest cooling centered around the South
Pole and Dome C. In addition, the
14-year temperature decline in the dry valleys occurred in the summer
and autumn, just as most of
the 35-year cooling over the continent as a whole also occurred in the
summer and autumn. The 13
authors laid down a challenge to the climate models which predict
polar warming, not the cooling actually
experienced, "Continental Antarctic cooling, especially the
seasonality of cooling, poses challenges to
models of climate and ecosystem change."
East Antarctica. Cremer et al. report that nearly all available
Antarctic terrestrial and marine records
show the latest thousand-year period "is generally marked by distinct
cooling leading to glacial readvances,
more extensive sea-ice, lower precipitation, and lower
bioproductivity."
Interior. Thompson and Solomon (2002) also report a cooling trend for
the interior of Antarctica, while
sea-ice concentration has increased and the length of the sea-ice
season has increased over much of
eastern Antarctica and the Ross Sea."
Sea Ice. Further evidence that the Antarctic as a whole is in the
midst of a cooling trend comes from
the study of Watkins and Simmonds (2000). Reporting on trends in a
number of Southern Ocean sea ice
parameters over the period 1987 to 1996, they found statistically
significant increases in sea ice area
and total sea ice extent, as well as an increase in sea ice season
length since the 1990s. Combining
these results with those from a previous study revealed these trends
to be consistent back to at least
1978. And in another study of Antarctic sea ice extent, Yuan and
Martinson (2000) report that the net
trend in the mean Antarctic ice edge over the last 18 years has been
an equatorward expansion of
0.011 degree of latitude per year. More recently, LIU et al. (2004)
confirmed a general increase of
Antarctic sea ice, on going since the late 1970s.
Scientifically, IPCC and S.139 policy advocates have a lot of
explaining to do before they can expect
whole societies to undergo an economically impoverishing culture shift
in deference to a theory which
appears so patently wrong on one of its key pillars.

Could quasars be us looking on from the top of black holes with

There is no such thing as centrifugal force.

Latest estimates are that the world will warm by an incredible
11C this century and its not likely stop there until it gets to
200C
.. Yanks and their big cars are to blame.
In April 2, 2001 a Time-CNN poll that says a majority of Americans
are concerned about global warming. Now why would that surprise
anyone? For the last decade the media has conducted an all out
campaign to push the concept of global warming. In fact, the former
Vice President conducted a seminar for Television Weather
Broadcasters on how to sell global warming. It must be emphasized
that during all this time the media never once presented a
conflicting opinion. However, there are, in fact,
17,000 scientists who signed the Oregon Institute Petition which
states that there is no scientific evidence to support human caused
global warming.
The media has also failed to cover the fact that in a briefing on
global warming before congressional staff, members of the press and
scientists, Professor Richard S. Lindzen of the Massachusetts
Institute for Technology assailed the politically driven work of the
United Nations’’ Intergovernmental Panel on Climate Change (IPCC),
specifically its pattern of misrepresenting the work of its
contributing scientists to fit a preconceived agenda.
Richard S. Lindzen is the Alfred P. Sloan Professor of Meteorology at
the Massachusetts Institute of Technology. He is a lead co-author of
Chapter 7 of the IPCC’’s forthcoming Third Assessment Report. He is
also a consultant to the Global Modeling and Simulation Group at
NASA's Goddard Space Flight Center and a Distinguished Visiting
Scientist at California Institute of Technology's Jet Propulsion
Laboratory. One of the world’’s foremost atmospheric scientists, Dr.
Lindzen received his AB, SM, and PhD degrees from Harvard University.
There is a whole another side to the story, but it is not politically
correct to mention it in any media outlet. After all, if you don’t
believe in global warming you are against Mother Earth.

click on 'more shows' , then radio 4 and science
Maybe if you spent less time listening and watching "shows" and more
time with real books, or better yet, got a job in the real world, you
wouldn't be pulling silly ideas out of your ***** on a regular basis.

A quote from Bill Bryson:
"I don't have any ambition to make great literature. I'll do anything to
keep my kids in Reeboks."
And here's a quote from a review by physics.about.com:
"Unfortunately, the very nature of a book which intends to chronicle
the universe in all its glory is limiting, and even a skill such as
Bryson's cannot overcome the shallowness of the science contained therein."
Gee, I'm impressed.

Due to centrifugal forces the equatorial diameter is bigger than the polar one , and one
weighs less at the poles . What about spinning stars like neutron or black holes . They must be like
flattened discs . So light could escape from the North and South poles , we might even be able to
visit one and get near its north pole and then escape blowing a raspberry
Could quasars be us looking on from the top of black holes with light climbing out of the
gravitational well and undergoing an enormous red shift ?
