تعاليق : شخصيا أختلف مع من يدعي أن البشر على عقل واحد وقدرة واحدة ..
أعتقد أن هناك تمايز أوجدته الطبيعة ، وكرسه الفعل البشري اليومي , والا ما معنى أن يكون الواحد منا متفوقا لدرجة الخيال في حين أن الآخر يكافح لينجو ..
هناك تمايز لابد من اقراره أحببنا ذلك أم كرهنا ، وبفضل هذا التمايز وصلنا الى ما وصلنا اليه والا لكنا كباقي الحيونات لازلنا نعتمد الصيد والالتقاط ونحفر كهوف ومغارات للاختباء

The Voyager 1 and 2 Saturn encounters occurred nine months apart, in November 1980 and August 1981. Voyager 1 is leaving the solar system. Voyager 2 completed its encounter with Uranus in January 1986 and with Neputne in August 1989, and is now also en route out of the solar system.
