Scientific subjects are very important to your and I's daily lives! Astronomy, chemistry, and basic cell science takes place all around us! It would be scary to live in a world we don't understand, wouldn't it? But, studying the science around us can ease that. There's even a science to making a daily cup off coffee, as the coffee beans saturate hot water in the coffee maker. Understanding these types of things is very important, otherwise we wouldn't know how many things work, like how ice melts or how many days a year we have due to the orbit of the Earth!
Caesar's bad traits were really a matter of perception. He achieved much success as a military leader who consolidated power and defeated enemies which led to amassing large amounts of foreign territory. He was very unpopular with the aristocrats of his time due to a number of his policies. He favor the poor and that angered the wealthy in his land. He also was suspected of aiming to become King of Rome due to his massive amount of power, this was not supported by the political system or the people of his time. He also had no fear of violence, even on massive scales. He committed many massacres on people, some in other lands, some who he promised retribution to due to being held captive as a child.
