Hi
Einstein created theories which proved that things like light, gravity, and matter were connected with each other.
I hope that's help !

The Age of Exploration gave civilizations a concept of how big the world really was, started trading systems with other countries, led to expansion and gathering natural resources such as iron, coal, etc. The negative effects are that expansion led to the destruction of smaller cultures and civilizations.
Champollion inscribed this copy of the published paper with alphabetic hieroglyphs meaning ‘à mon ami Dubois’ (‘to my friend Dubois’). Champollion made a second crucial breakthrough in 1824, realising that the alphabetic signs were used not only for foreign names, but also for the Egyptian language and names. Together with his knowledge of the Coptic language, which derived from ancient Egyptian, this allowed him to begin reading hieroglyphics.
