Astronomy:
A structure known as the African Stonehenge in present-day Kenya (constructed around 300 B.C.) was a remarkably accurate calendar. The Dogon people of Mali amassed a wealth of detailed astronomical observations. Many of their discoveries were so advanced that some modern scholars credit their discoveries instead to space aliens or unknown European travelers, even though the Dogon culture is steeped in ceremonial tradition centered on several space events. The Dogon knew of Saturn’s rings, Jupiter’s moons, the spiral structure of the Milky Way and the orbit of the Sirius star system. Hundreds of years ago, they plotted orbits in this system accurately through the year 1990 . They knew this system contained a primary star and a secondary star (now called Sirius B) of immense density and not visible to the naked eye.

Answer:
"Washington appears to have been one of those rare individuals in world history who fit the needs of his time. What made Washington a great leader was his understanding of what had to be done. As president, Washington realized that the new Constitution had to be made to work if democracy was to take root on American soil. This would not happen if he had chosen to become a lifetime king or if federal laws were ignored. It was also clear to Washington that the new experiment in a representative government would likely fail if the infant nation became involved in European conflicts."
