Answer:
Einstein's greatest equation, E = mc2, is a triumph of the power and simplicity of fundamental physics. Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously. Thinking about problems in this way enabled us to discover the fundamental particles that make up our Universe, to invent nuclear power and nuclear weapons, and to discover the theory of gravity that describes how every object in the Universe interacts. And the key to figuring the equation out? A humble thought experiment, based on one simple notion: that energy and momentum are both conserved. The rest? It's just an inevitable consequence of the Universe working exactly as it does
Answer:
A controversial Creek Indian leader in the 1780s and 1790s, Alexander McGillivray was one of many Southeastern Indians with a Native American mother and European father.
More men were drawn to the Roman army than to Alexander's army. The Alexandrian army was made up of Greek and Macedonian warriors. Alexander's troops fought for Greece and dignity. The Greek warriors' dignity provided them an advantage in those important fights. The Greeks had been fighting the Persians for so long that they had developed a loathing for them. Some of Alexander's warriors were not as powerful because, unlike the Romans, he had to seek support wherever he could find it. Alexander had no primary spot to which he returned after fights.
