This thread is essentially the Ancient Giza Rubic cube part 2, and in this thread I will demonstrate how the Ancient builders of the Giza pyramids
applied a practical use to them in calculating the rotational speed of earth.
In this thread I will do a set of calculations which demonstrates that the distances 411, 440, 201.5 (the side base distances of the pyramid
represents time displacement values). I will show how the gaps distances between the pyramids represent displacement distances, how the side base
values and gap displacements can be fed into velocity = distance / time calculations to measure rotational speed of earth.
I have placed this in Skunk works because i don't want this thread to get into tit tat arguments over appropriate thread category.
Firstly for a basic definition on the nautical mile.
The perimeter (circumference of earth) is divide-able into 360 degrees and then each degree divide by 60 minutes of arc. The 360 x 60 = 21600
nautical miles for measuring the circumference of earth. Therefore 1 nautical mile is the angular distance of 1 minute of arc on the earth's surface
and at the equator the single nautical mile measures as = 1852 metres.
If you try and go into the history of where the nautical mile originated you will find no definitive answer, other than pointing to ancient origins.
What i am presenting in my thread collaborates that the contemporary use of 1852 metres was also in use at the time the pyramids at Giza were built,
(indicating what we consider/refer to be a contemporary value is in fact very old usage). The above was my words but in the quotes below is a more
Ok i hope you like calculations because this is where it starts:
The nautical mile or minute of an arc at the equator is made up of 1852 metres. The Egyptians Royale cubits 0.52375 metres converts this to 3536.03818
egyptians Royale cubits.
The equatorial diameter of earth allows is 21600 nautical miles x 3536.03818 eyptians Royale cubits = 76378424.688 eygptians Royale cubits cubits.
Therefore the ratio of distance of the Giza east west (longitudinal) 1417.5 Plateau direction divided by the earth equatorial diameter.
= (76378424.688/ 1417.5)
= 53882.48655 ( which represents the number of times the Giza East West intervals divides up the equator)
Recap a single nautical mile is the arc distance of about 1 minute of a degree out 360 degrees that divide the circumference. A single
1 minute of a degree is divide-able into 60 arc seconds.
Therefore the total arc seconds in 360 degrees = 360 x 60 x 60 = 1296000 arc seconds
1296000/ 53882.48655 = 24.052342 arc seconds. This value means that is there are 24.052 arc seconds in the east-west length of Giza length 1417.5.
I will round to 24 arc seconds.,
The rounding effect (24.052342 -24) x 53882.48655 = 2820 arc seconds variance, (or look at it as 2820 / 24 = 117.5 lengths of giza) as the variation
factor in earths circumference distance at equator, (because the surface has hills, moutains , bumps etc). I will show later the effect of rounding is
negligible on the result.
Recap a few things again:
There are 24 arc seconds in the east-west length of Giza 1417.5 plateau length ( 1417.5 measured in Eygptians Royale cubits) in the plateau east west
longitudinal direction .
The total circumferential arc seconds in 360 degrees = 360 x 60 x 60 = 1296000.
Therefore (86400/ 1296000) x 24 (arc seconds)= (0.066666) x 24 = 1.6 seconds which is the number of seconds that pass on the 24 hr clock/watch hand
for every 24 arc seconds.
Note: In the 24 hour time scale there are 24 hours 60 minute and 60 seconds. That makes for 24 x 60 x 60 = 86400 seconds, which is where the value
came from above. The arc second quantities cancel eachother so 1.6 second result is seconds measured on the 24 hr clock/watch minute/sec hand.
I will do a set of calculations below which demonstrates that the distances 411, 440, 201.5 represents time displacement values (measured in the 24 hr
clock/watch minute/sec time scale). I will show how the gaps distances between the pyramids represent displacement distances, and the side base
distances of the pyramid are time displacements values (which are determined in calculations which I perform). The displacements and times can be fed
into velocity = distance / time calculation to measure rotational speed of earth.
The gap distances ( 152 + 213) = 365
(365/ 1417.5) x 1.6 seconds = 0.4119929
the diagram above shows the 152 gap = (353.5 - 201.5)
and the other is the 213 gap
The arc seconds in 1732 north south distance 24 x (1732/1417.5) = 29.32486
Therefore (86400/ 1296000) x 29.32486 = (0.066666) x 24 = 1.9549 seconds the number of seconds that pass on the 24 hr clock/watch hand for every 24
(365/ 1732) x 1.9549 seconds = 0.4119929 ( seconds in 24 hr/minute second clock)
What does this value 0.411 mean then. I see it as meaning the fraction of time on the 24 hour clock (in seconds) when the earth moves ( rotates its
position) against the sun (stationary point). From an observer standing on ground they appear stationary and its the sun which is the thing moving in
an arc across the sky. Therefore think of it in terms of the earth is rotating its position in increments of 1417.5 (east west direction) distance,
and with each increment taking 24 arc seconds (or 1.6 seconds as measured on the 24 hr wrist watch of the ground observer).
This 0.411 seconds appears to me to be a value which the Ancients used for a velocity measurement of the earths rotation, i.e. 365 cubits per 0.4119
seconds, they were happy with 0.411 seconds accuracy and this rounding has negligible effect on accuracy of rotational speed value.
365 cubits per 0.411 seconds = 885.9375 cubits/ second earths circumferental rotational speed.
convert 885.9375 cubits/ second to metres per second using 0.52375 metres converter factor
= 464.01 metres/ second
quote value below from internet comparing result above with known rotational speed of earth
Then we divide the length of a day into the distance a point on the equator travels in that period: 40,075 km/23.93 hours = 1,675 km/hour, 465
meters/second. The speed of the Earth's rotation changes as you go North or South away from the equator.
My next few posts to this thread will add calculations for 201.5 and 440 and demonstrate that the pyramids had practical application, certainly not
just static tombs for Bronze/copper age civilisation.
