1 янв 1749 г. - Invention of Lightning Rod
Описание:
Benjamin Franklin invented the lightning rod as part of his scientific mission to prove the existence of electricity in lightning. The lightning rod was a sharpened metal pole that would, in theory, and as it turned out in practice, attract lightning if it was made of electricity.Добавлено на ленту времени:
