“I call France…” "...ادعو فرنسا"

perbosc
:صوت تأتينا من الاسكندرية
"...ادعو فرنسا"
سمعنا نتائج مدارس الاسكندرية
وسمعنا ايضا نتائج المدارس في اسوان
:علينا ان نتكلم الآن
44°08'الزاويه : '40°20 شمال خط العرض
الملاحظه الاهم هي في منأى من الاسكندرية
في الجنوب من اسوان
بالضبط على مدار السرطان
.( 2296 كيلومتر في جنوب lafrançaise)
وهذه الملاحظه هي بداية الصيف
عند منتصف النهار والشمس والاشعه الشمسيه تأتي مباشرة من وضع الراسي
في هذا المكان ، في هذه اللحظة ، لا يوجد الظل

Calculation of the circumference of the Earth:
360 x 2296/(20+40/60) = 39.994 km
The voice comes to us from Alexandria: “I call France…”
We heard the results of the schools in Alexandria .We have also heard the results of the schools in Aswan. We must speak now: “20°40' for a latitude of 44°08' north.” The most important observation is far away from Alexandria: 72 km in the south of Aswan. Exactly on the Tropic of Cancer (2296 km in the south of Lafrançaise). This observation is the start of the summer. When it is solar midday, the solar rays are coming straight down from the vertical. At this place, at this moment, there is no shade.

Pupils, الطلاب

Céline

هي تصوير هذا الحدث
المجموعة الاولى هي انطباعات

She filmed this event. She collected the first impressions.

Anne-Justine
انني اقدر هذا الفيديو
ومن الغريب جدا والوعيد
ودعانا فرنسا
يمكننا ان نسمع صدى صوتنا


I appreciated this videoconference. It was very intimidating and strange. They called us: “France”. We could hear the echo of our voice.

Arnaud

في البداية ، أود أن معقد
بعد ذلك ، كان أفضل

At the beginning, I found that complicated. Afterwards, that was better

Marjorie

كان آخر ساعة
هو ما قال لنا الاستاذ لنا
في ندوة استغرقت نصف ساعة فقط
لذا اشعر بخيبه الامل قليلا

That was to last one hour. It is what our professor had said to us. The videoconference lasted only one half hour. Therefore I am disappointed a little bit

Cwisona

انني اقدر هذا الفيديو
نحن لا نرى في افلام الصور اسوان ، ومن المؤسف
كنت اتمنى ان نراهم
نحن لا نرى بداية ونهاية تلك كليب في الاسكندرية
تعديل العموديه هي مشكلة كبيرة بالنسبة لهم ولنا أيضا
وايضا هذه المشكلة التي لم نكن لقاء
المثبتات التي خففت تحت تأثير حرارة
ويشكروننا على جهودنا المقاييس
كلنا اعجاب كبير في مكتبة الاسكندرية

I appreciated this videoconference. We did not see the images filmed in Assouan, it is a pity. I would have liked to see them. We did not see the beginning and the end of those filmed in Alexandria. The adjustment of verticality was the big problem, for them and for us too. They had also this problem which we did not encounter. Fixings which softened under the effect of heat. They thanked us for our measurements. We all were very impressed by the great library of Alexandria .
