Egypt Magic [1321]
January 4, 2014, ·
How did the ancient Egyptian prove the earth’s spherical shape by calculating the diameter of the Earth?
A scientific heritage based on simplicity in thought and union with nature:
From about 270 BC in the great city of Alexandria
The circumference of the Earth was measured …
In the modern era, this required satellites, missiles, measurements and monitoring.
And they knew that the circumference of the earth is approximately 40,030 km.
Bs Eratosthenes in Alexandria from about 270 BC
He calculated that 40,000 km had already met it without him
No satellites, no planes, no need …
He knew it with the mind and knowledge of Alkmtayn
What was based on simplicity in thought and solutions before anything …
Eratosthenes, born in the city of Sirin, Quria, or Shahat, in eastern Libya today
On the Mediterranean coast …
I was raised, educated and lived in Alexandria …
Eratosthenes heard that he was in Son, which is Aswan
It’s at the summer solstice on June 21
The sun’s rays are completely perpendicular to the obelisks
And no shadow appears to her …
Speech entered his brain and stuck with him …
He told you, well, stay like that on the day of the summer solstice
If sticks were placed on the ground here in Alexandria, they would not appear …
But of course, he appeared strayed to the sticks …
He went along the angle of the stave from the side of the sticks to the ground.
And 7.2 degrees of tilt ratio of stray …
With his application of the theory that the Earth is round
Of the sciences Alkmettin, as well as philosophers such as Pythagoras and Aristotle
And also, the theory of cuboid rectangles
It is any line that cuts two parallel lines while the inner angle of the first line remains.
It is the same as the outer angle at the second line …
It simply means that the Eratosthenes operator is like this for the Earth
And two lines are tightened
A line representing the ray of the sun on Aswan
And a parallel line represents the ray of the sun on Alexandria
And complete the two lines for the whole ball
Of course, at the midpoint of the circle
The intersection of the ray line drawn with the stick line
The beam had the same inclination of 7.2 degrees …
Makdbash, news of Eratosthenes went for one hire.
It measures the distance from Alexandria to Aswan, which met approximately 800 km.
Or with their scale of 5000 students
And this Greek scale is approximately 185 meters.
The important factor will be the proportion, and the proportionality factor is 7.2 degrees to 360 degrees.
A ratio of 1 to 50 appeared.
He went to 50 times the 5000 stadiums or 800 km to get the result
Which is 250,000 stadia or 40,000 km …
And this is the circumference of the Earth …
The important thing here is how to think simple atypical
And how to use your data efficiently without complications …
It also highlights the importance of obelisks and the measurement of shadows and times of passage of the sun …
I mean, the topic will not remain easy on Eratosthenes
If it were not for it, there were searches for it
Sunlight, its perpendiculars, its times and its accurate calculation
And also research on the spherical Earth …
Quantities were geniuses at exploiting nature.
The great scientific heritage that our ancestors left for us can all be based on
Simplicity in thought and union with nature and dealing with it as it is
A puzzle that carries its solutions together at the same time …
