Charles Fulton lived a relatively private life compared to his father's notable achievements in transportation and engineering.

A hydrologist is a scientist who studies the distribution, movement, and properties of water in the Earth's atmosphere and on its surface. They analyze water cycles, assess water quality, and manage water resources to address issues like flooding, drought, and pollution. Hydrologists often work in fields such as environmental science, geology, and engineering, contributing to sustainable water management and conservation efforts.

Gunpowder is considered one of the most important inventions of the golden age because it revolutionized warfare and military strategies, leading to the rise of powerful empires and the decline of feudal systems. Its introduction changed the dynamics of conflict, allowing for more effective artillery and firearms that transformed both defensive and offensive tactics. Beyond military applications, gunpowder also spurred advancements in mining and construction, facilitating infrastructure development.
