1 янв 1835 г. - Man Made Eclectrical Lighting
Описание:
Before Edison made his incandescent light bulb, British inventors experimented with electricity using the arc lamp. In 1835, the world's first constant electric light was made, and for years after, inventors and scientists worked to perfect it. This would eventually give birth to a era of electricity across the world.Добавлено на ленту времени:
