نيكولا تيسلا

نيكولا تيسلا واحد من أذكى المخترعين في التاريخ، والرجل اللي غيّر حياتنا من غير ما نعرف. أغلب الأجهزة اللي نستخدمها اليوم تعتمد على التيار المتناوب اللي هو اخترعه قبل أكثر من 120 سنة.

📌 ١. يشوف الاختراع قبل ما يسويه
كان يتخيل الجهاز كامل في عقله: شكله، صوته، حتى حرارة القطع. يجربه ذهنياً، ويصلّح الأخطاء قبل ما يبنيه فعلياً.
الفائدة: يقلّل تجارب الخرابيط ويوفر وقت وجهد.

📌 ٢. أول من حاول ينقل كهرباء بدون أسلاك
بنى برج “واردنكليف” سنة 1901 بهدف يوصل كهرباء للعالم عن طريق موجات الأرض. مشروع سابق لعصره، لكن الفكرة نفسها رجعت شركات اليوم تشتغل عليها.
الفائدة: تخيّل كهرباء توصل لبيتك بدون أي سلك… حلم تيسلا من زمان.

📌 ٣. ينام ساعتين بس في اليوم
كان يعيش على نوم خفيف جداً… عقله شغّال 24 ساعة.
النتيجة: أكثر من 300 اختراع مسجّل باسمه.
طبعاً ما ننصح أحد يقلده.؟
