Нужен перевод. the gradual growth of our knowledge of electricity. the greek philosopher thales knew that amber rubbed with fur or wool would attract small pieces of straw and other light materials. early chinese also knew this. they used this knowledge to make a magnetic compass – a special iron needle that rotates in any horizontal direction. the natural magnetism of the earth attracts the needle so that it always tums to points towards the north. the compass made navigation of the ocean simpler and safer. one of the first books showings the connection between magnetism and electricity was written by dr. william gilbert in 1600. it was generally thought that there were two different kinds of electricity frictional and static electricity – the kind you make when you rub amber with wool – and kind stored in a cell that can be changed into electric current. now we know the two kinds are the same.
Греческий философ Фалес знал, что янтарь, протертый мехом или шерстью, привлечет небольшие кусочки соломы и других легких материалов. Ранние китайцы тоже это знали. Они использовали это знание для создания магнитного компаса - специальной железной иглы, которая вращается в любом горизонтальном направлении. Естественный магнетизм земли притягивает иглу так, чтобы она всегда тянулась к северу. Компас сделал навигацию по океану более простой и безопасной. Одним из первых показаний книги была связь между магнетизмом и электричеством, написанная доктором Уильямом Гилбертом в 1600 году. Обычно считалось, что существует два разных типа электричества: фрикционное и статическое электричество - то, что вы делаете, когда вы втираете янтарь шерстью - и вид, хранящийся в ячейке, который может быть заменен на электрический ток. Теперь мы знаем, что оба вида одинаковы.
