اقتباس
(احتل التفكير بعلم الفلك عقل الانسان منذ بداية التاريخ،
بدأ علم الفلك التقليدي مع اكتشاف هيبارخوس مبادرة الاعتدالين المحورية في القرن الثاني قبل الميلاد، ومع ذلك، تظهر رسومات الكهوف التي تعود إلى عصور ما قبل التاريخ أن القدماء كانوا على علم بالاعتدالين والانقلابين قبل 40000 عام، وفقا لما اكتشفه)
اقتباس ٢
(في نحو عام 360 قبل الميلاد عندما اقترح أفلاطون فكرته لتفسير حركات الأجرام السماوية. ادعى أفلاطون أن الدوائر والكرات هي الشكل المفضل للكون وأن الأرض تقع في المركز وأن النجوم تقبع على الكرة الخارجية، تليها الكواكب والشمس والقمر. مع ذلك، لم يكن هذا كافيًا لشرح حركة الكواكب المرصودة. خلال الفترة من 127 إلى 141 بعد الميلاد، استنتج بطليموس أن الأرض كروية بناءً على حقيقة عدم قدرة الجميع على رصد الكسوف في نفس الوقت وأن الراصدين في الشمال لا يمكنهم رؤية النجوم الجنوبية.حاول بطليموس حل معضلة حركة الكواكب التي لم يكن فيها الرصد متسقًا مع المدارات الدائرية المثالية للأجرام. )
