00:00:00.760 --> 00:00:03.735
لنتخيل نحاتاً يقوم بنحت تمثال،

00:00:03.760 --> 00:00:06.136
يحفر الرقاقات بإزميله.

00:00:06.160 --> 00:00:09.216
كان لدى (مايكل أجلو) طريقة أنيقة
في وصف ذلك عندما قال،

00:00:09.240 --> 00:00:12.136
"كل كتلة من الحجر تحمل تمثالاً بداخلها،

00:00:12.160 --> 00:00:15.256
وهي مهمة النحات أن يكتشفه."

00:00:15.280 --> 00:00:17.696
ولكن ماذا لو كان يعمل في الإتجاه المعاكس؟

00:00:17.720 --> 00:00:19.576
ليس من كتلة صلبة كن الحجر،

00:00:19.600 --> 00:00:21.296
لكن من كومة من الغبار،

00:00:21.320 --> 00:00:25.696
يقوم بلصق الملايين من تلك
الذرات معاً بشكل ما ليصنع تمثالاً.

NOTE Paragraph

00:00:25.720 --> 00:00:27.216
أعلم أنها فكرة سخيفة.

00:00:27.240 --> 00:00:28.976
إنها مستحيلة على الأغلب.

00:00:29.000 --> 00:00:31.936
الطريقة الوحيدة للحصول على
تمثال من كومة من الغبار

00:00:31.960 --> 00:00:34.296
هي إن قام التمثال ببناء نفسه

00:00:34.320 --> 00:00:38.456
لو كنا بطريقة ما قادرين على إجبار الملايين
من تلك الذرات على الإجتماع معاً

00:00:38.480 --> 00:00:39.760
لتشكّل التمثال.

NOTE Paragraph

00:00:40.320 --> 00:00:41.856
الأن، ورغم غرابة ذلك،

00:00:41.880 --> 00:00:46.016
هذه هي بالضبط تقريباً المشكلة
التي أعمل عليها في معملي.

00:00:46.040 --> 00:00:47.456
أنا لا أبني بالحجارة،

00:00:47.480 --> 00:00:48.856
أنا أبني بالمواد المتناهية الصغر.

00:00:48.880 --> 00:00:53.256
إنها تلك الأشياء المذهلة مستحيلة الصغر.

00:00:53.280 --> 00:00:56.576
إنها صغيرة جداً لدرجة أنه لو كانت
أداة التحكم هذه جزيئاً متناهي الصغر،

00:00:56.600 --> 00:00:59.536
ستكون الشعرة البشرية بحجم هذه الغرفة.

00:00:59.560 --> 00:01:02.376
وهي في قلب مجال نطلق
عليه تكنولوجيا النانو،

00:01:02.400 --> 00:01:04.215
وأنا متأكد من كوننا سمعنا به جميعاً،

00:01:04.239 --> 00:01:07.696
وسمعنا جميعاً كيف أنه سيغير كل شيء.

NOTE Paragraph

00:01:07.720 --> 00:01:09.216
عندما كنت طالب دراسات عليا،

00:01:09.240 --> 00:01:12.576
كان أحد أكثر الأوقات إثارة
للعمل في مجال تكنولوجيا النانو.

00:01:12.600 --> 00:01:15.816
كانت هناك اكتشافات علمية تحدث طوال الوقت.

00:01:15.840 --> 00:01:17.256
كانت المؤتمرات تضجّ،

00:01:17.280 --> 00:01:19.960
كانت أطنان من المال
تصب من المؤسسات الممولة.

00:01:20.760 --> 00:01:22.016
والسبب هو

00:01:22.040 --> 00:01:23.856
عندما تصبح المواد صغيرة جداً،

00:01:23.880 --> 00:01:27.496
فهي تخضع لفيزياء مختلفة
عن التي تحكم المواد العادية،

00:01:27.520 --> 00:01:29.016
مثل تلك التي نتعامل معها.

00:01:29.040 --> 00:01:30.976
