Я только перевод)) Вот : Характер электричества
Древние греки знали, что когда кусок янтаря протирается шерстью или мехом, он достигает силы притягивания легких предметов. Позже было изучено явление, а слово «электрический», после греческого слова «электрон», означающее «янтарь». Многие ученые исследовали электрические явления, а в течение девятнадцатого века много открытий о природе электричества и магнетизма, которые было установлено, что если стержень-воск-стержень протирается шерстяной тряпкой, а стержень из стекла протирается шелковой тканью, электрическая искра пройдет между швом-восковым стержнем и стеклянный стержень, когда они прижаты друг к другу. Кроме того, было обнаружено, что между ними действует сила притяжения. Однако восковой стержень отталкивает наэлектризованный герметизирующий воск, а также электрифицированный стеклянный стержень отталкивается аналогичным стеклянный стержень.
Были разработаны идеи, что есть два вида электричества, которые называются смолистым электричеством, и что противоположные виды электричества привлекают друг друга, тогда как подобные виды отталкивают друг друга.

Ivan Tsarevich - one of the main characters of Russian folklore. As a fairy tale character, he appeared in the late XVIII-early XIX century.
Ivan Tsarevich appears in fairy tales in two different guises:
positive character, struggling with evil, which helps an injured or weak. Very often in the early tales Ivan Tsarevich poor, lost parents, pursued by enemies, is not aware of his royal ancestry. In such tales as a reward for heroic behavior and good works, Prince Ivan gets back his kingdom, the throne, or finds his royal parents. But even if it was originally the prince, in the end of the story, he usually gets kind of prize in the form of another half a kingdom, the royal or king's daughter, magic or an expensive horse, precious or magical objects, or even further mind or magical abilities
