Dear Science and astronomy Friends,



“SUN has Mean equatorial radius: 696000 km (109.1 x Earth) and about similar
times of (the Diameter of The SUN) away from the Earth”


FEB 2004) : Measuring the Earth:


How long will it take and how far we need to go to measure the Earth. Similar to
the experiment “4)” above can do all for you. But all need to do is use local
time. When sun comes over head (No east or No West). And select two place A & B
of at least 2 KM distance apart NORTH and SOUTH and do the measurement same time
at both place as follows.



We can use one control place “S” in South or “N” in North about 50 Km away to
correct any minor errors from short distance “2 KM” experiment.



Example of Latitudes longitude finding at the Local time. – for tropical of
cancer @ Local time you need to find the correct time when sun is on the head
with no shadows East or West. and need to be there at LOCAL time of 12:00 NOON
which may be 12 + MM depending on the place where you go – Longitudes.



Experiments done at the Place A & B on 12 Noon IST will have shadow towards
East/West. Depending your positions in India (West/ East of 82.5 E Longitude).
And so accordingly you will get shadow East/West. Measure the length of that of
shadow of 3 Meter pole. and find the Tangent = shadow/ pole - will give u the
angle. Say example : shadow = 600 mm at that time. So 600/3000= 0.2

so anti tangent is an angle of 11o.30' degree. so you are 11..30' West/East of
IST line means IF shadow is East than U R WEST and at 82.30' - 11.30' = 71
degree East longitude.



(If shadow is in the EAST than - you are IN the East you need to do experiment
Next day before 12 IST and preferably to start more than an hour before to set
up all arrangements)



Now u find exact time when to take results of the experiment. when there is no
shadow to the EAST/WEST - at 12Noon + (11.3o' x4) = @12 + 46 PM U have 46
minutes to do that. To take the next accurate place readings. When there is no
shadow in East/West but to the NORTH/SOUTH ONLY (depending your position North
or south of the SUN in India or in the world) at that place at that time. GPS
may be in correct to show that but not the SUN.



Now measure the length of the shadow in accuracy of mm fractions @places “A”,
“B” & “N” or “S”@ same time.



If the Difference of the length of shadow is 1mm at places “A” and “B” same time
at Local time when sun comes over head –(NO shadow on East or West) the
calculations will be simplified as follows.



Anti tan 1/3000 gives the angle made by shadow on the Earth surface gives the
angle = at the centre of the Earth by the 2 KM distance on the surface of the
EARTH. Eg about 1.1' (1+') and find the Circumference of the Earth = 360 degree.
(around 40000 Km)



Similarly Controlled reading at “N” / “S” will help you to find accuracy eg long
distance measure will give more accuracy than 2KM and correct your readings from
that 50 KM distance experiments. (that will give you about 23.5mm shadow
Difference than that of “A” and 23.5+1 mm than that of “B”) so calculate the
tangent and angle and circumference of the Earth and Diameter or R for the
Earth.

TO SIMLYFY MORE and Easy work, Let One of the "N" OR "S" be Either Delhi Jantar
Mantar or JAIPUR - JANTAR MANTAR.

We are very rich in our Astronomy engineering - particularly JAIPUR is the
Richest in that sense. Jaipur has very good working observatory (VEDH SHALA)
with guiding facility.



According to an expert guide (Hanumant Singh - also expert in astronomical
calculations)- that ancient observatory place can measure 1/6 of the second in
time and that is equal to 0' 2.5" size of the angle of the sky observation
accuracy. And that all works local timing and longitude - latitude of the place.
Only the persons required to work for it.



We should utilize that place with aided observation with Venus transit of 8 June
2004. TEAM A - working with Local observatory guides and Team B working with
OPTICAL aids at the same place to complementary work. That is the best place for
us to utilize the observation at that place and that is relay a Golden
opportunity for Jaipur and users too.



(Delhi and Jaipur observatory – Vedh Shala are constructed such a way that it
can work locally @ that Longitude Latitude and also at a LOCAL time of that
place. So we do not need to find the place location of Longitude-Latitude while
working there nor the local time of that working place (Auto Sun Dial activity)
– nor we need toys like GPS nor sophisticated instruments. Not only that but
many of such astronomical activities – One like coming VENUS TRANSIT on 8 June
2004 also needs to be observed and activity to be worked in same environment
such as Local time and longitude Latitude, so many of planetarium places and
activity are just nothing in comparisons to such VITAL places as others has to
use their toys of GPS and telescopic compass and Leveling like a Theodolites).
So if we use this place on the day 8 June2004 for a Tenus Transit time activity
then instead of So called planetariums – as Venus transit is the phenomenon of
the place of JANTAR MANTAR and not Planeterium activity. – people will realize
the importance of such a place who even Astronomy lovers and planetarium
authority - who forgot that place and its importance.
