One of the biggest omissions in terrrestrial studies is the absence of
rotational dynamics applied to crustal evolution and motion,this being
mainly due to factors expressed here day in and day out.

The place to begin with rotational dynamics and its geological
consequences is to look at stellar rotational dynamics first in order
to get a clear perspective of the behavior of a rotating celestial
object with a viscous composition.It is well known that stars of
roughly the same size but with different maximum Equatorial rotational
speeds will demonstrate spherical deviation,there are many examples on
the web but the following one will do despite the difference in
stellar magnitudes -

http://www.jpl.nasa.gov/releases/2001/release_2001_150.html

There are 3 binding correlations involved for a given rotating
composition in a viscous state -

1 - Maximum Equatorial speed

2 - Differential rotation

3 - spherical deviation

I have a 9.25 inch Celestron SC scope ... and Im interested in getting
a new 13 mm Ethos eyepiece. Im interested mostly in galaxies and
Nebula ... would this eyepieve be appropriate for me or would the
magnificatin make everything too dim?
Many thanks

Does anyone know of a howto guide or article for Winjupos? I'm
reading the help file built into the application and am not
penetrating on how to use it. - Canopus56

I see no reason to be apprehensive about the Large Hadron Collider.
So far nothing untoward has hap

For the past few decades, there has been a lot of speculation, and
some proof, that things in or from the heavens can and do radically
and materially affect things here on Earth. It was around 1980 that
Luis Alvarez tied the extinction of the dinosaurs to the impact of a
sizeable asteroid striking the Earth about 65 million years ago. Now
another, more recent sequence of events has come to my attention, and
I thought I would share this with those who have an interest.

For the past week or so, I have been reading "The Cycle of Cosmic
Catastrophes: How a Stone-Age Comet Changed the Course of World
Culture" - by Richard Firestone, Allen West, Simon Warwick-Smith. The
authors attribute the extinction of the wooly mammoth, and other north
american megafauna, and the paleo-american Clovis culture, to a
probable comet strike at what is now Lake Michigan.

From the much heralded concept from 100 years ago -

"Einstein's first theory of relativity, which he published in 1905,
broke away from the Newtonian reliance on space and time as immutable
frames of reference. This theory was immediately recognized by the
scientific community as having profound implications for physics and
cosmology. "

http://archive.ncsa.uiuc.edu/Cyberia/NumRel/SpecialRel.html

The whole point of relativity is to expand the illegal choice Newton
give himself to an infinite amount of choices insofar as Newton
created an illegal hypothetical observer on the Sun (absolute frame)
as opposed to the Earth observer (relative frame) in applying a
resolution of retrogrades,again,the maneuver is both illegal and
false. . In relativity-speak these are known as 'frames of reference'
and you can create as many as you like to do whatever job is
needed.Like squirrels running around a circular cage,creating
scenarios occupies both the opponents and proponents of relativity,it
may be a nightmare for most people but they are content with their
lot.

There is nothing remotely difficult in determining natural noon and
applying the Equation of Time to create the 24 hour day and keep these
24 hour cycles rolling over as Monday into Tuesdays as we know them.

" hang two plummets, each by a small thred or wire, directly over the
said Meridian, at the distance of some 2. feet or more one from the
other, as the smalness of the thred will admit. When the middle of the
Sun (the Eye being placed so, as to bring both the threds into one
line) appears to be in the same line exactly you are then immediately
to set the Watch, not precisely to the hour of 12. but by so much
less, as is the Aequation of the day by the Table."

http://www.xs4all.nl/~adcs/Huygens/06/kort-E.html

There is no tilting Earth,no wandering Sun to the North,South,East or
West,just a simple observation when the threads line up and then the
24 hour day is created .The application to daily rotation in terms of
24 hours/360 degrees or 4 minutes of clock time for each degree of
East/West seperation is then possible making this a precious
astronomical feature with little to argue about.

This is how Nasa,following the lead of particpants here, treats the
same observation -

'THE SUN'S PATH IN THE SKY '

"There is another astronomical effect you should know about that can
change the time that the Sun is highest in the sky. This is a little
hard to explain, but it also has to do with us watching the Sun from a
tilted perspective. The Earth spins on its axis about 366 and 1/4
times each year, but there are only 365 and 1/4 days per year. This is
because we define a day not based on the Earth's period of rotation,
but based on the average time from noon one day to noon the next.
Gradually over the course of a year the Sun appears to go
'backwards' (West to East) around the Earth compared to the far away
stars (this is because we are really going around the Sun).
Subtracting this 1 time backwards from the 366 and 1/4 times forward,
we get the typical 365 and 1/4 days per year."

Scientific Accuracy of Quran amazes you

This message is based on an article titled "Highlights of Human
embryology in the Qur'an and Haidth" by Dr.Keith Moore, Professor of
Anatomy and Chairman of the Department, Faculty of Medicine, at the
University of Toronto.Dr. Moore points out that the study of how the
human embryo develops in the mother's womb could not progress
significantly without the use of microscopes. Microscopes were not
invented until the 17th century C.E., and were not used in this field
of study until the 18th century. Therefore, when Dr. Moore studied
certain statements in the Qur'an on this subject, he remarked, " I was
amazed at the scientific accuracy of these statements which were made
in the 7th century C.E.,"

The Qur'an in 39:6 states that God made us in the wombs of our mothers
in stages. Dr. Moore comments: "The realization that the embryo
develops in stages in the uterus was not proposed until the1940's...
