"لا تَقتصر الهندسة على بناء الأشياء فحسب، بل تتعلَّق بِحلِّ المُشكلات المعقَّدة الَّتي يُمكن أن تُغيّر العالم. يَحتاج العالم إلى المزيد من المُهندسين المتحمِّسين لخلق مُستقبل مستدام، والملتزمين بإحداث فرق. دعونا نُلهم ونمكِّن الجيل القادم من المُهندسين لمواجهة تحديات الغد."

THE ART OF ENGINEERING
"It all looked so easy when you did it on paper-where valves never froze, gyros never drifted, and rocket motors did not blow up in your face." -Milton Rosen, Director of Launch Vehicles And Propulsion
