Enrich fermi was a scientist and a physicist .He discovered nuclear fission and he led several tests releated to the use of nuclear power and his work was mostly on induced radioactivity by neutron bombardment and the discovery of transuranic elements or a nuclear reactor .His new find followed Marie Curies and Joliot’s discovery of artificial radioactivity .At age 14 he lost his brother from a minor throat surgery accident.In order to escape the pain of losing his brother ,Fermi buried himself in books about physics that fascinated him and soon got him into college with an entrance exam essay that was judged worthy of a doctorates degree .So you could say that his own loss of his brother motivated him to start making discoveries of his own in physics and on experimenting with neutrons. Hope this helped !

Answer:
Nubia and Ancient Egypt had periods of both peace and war. It is believed, based on rock art, that Nubian rulers and early Egyptian pharaohs used similar royal symbols. There was often peaceful cultural exchange and cooperation, and marriages between the two did occur. Egyptians did, however, conquer Nubian territory at various times. Nubians conquered Egypt in the 25th Dynasty.
Egyptians called the Nubian region “Ta-Seti,” which means “The Land of the Bow,” a reference to Nubian archery skills. Around 3500 BCE, the “A-Group” of Nubians arose, existing side-by-side with the Naqada of Upper Egypt. These two groups traded gold, copper tools, faience, stone vessels, pots, and more. Egyptian unification in 3300 BCE may have been helped along by Nubian culture, which was conquered by Upper Egypt.
Nubia was first mentioned by ancient Egyptian trading accounts in 2300 BCE. Nubia was a gateway to the riches of Africa, and goods like gold, incense, ebony, copper, ivory, and animals flowed through it. By the Sixth Dynasty, Nubia was fractured into a group of small kingdoms; the population (called “C-Group”) may have been made up of Saharan nomads.
During the Egyptian Middle Kingdom (c. 2040-1640 BCE), Egypt began expanding into Nubian territory in order to control trade routes, and to build a series of forts along the Nile.

2. Division of Federal and State Power
