Francis Hauksbee (1 янв 1705 г. – 1 янв 1705 г.)
Описание:
Francis Hauksbee, created electrical effects by putting some mercury into a glass globe, pumping out the air and then spinning it. When he did this in the dark, and then rubbed the globe with his bare hand, it glowed. (He didn't realise it, but he had invented the neon light!)Добавлено на ленту времени:
