Answer: was held on 26 April 1920 at the Smithsonian Museum of Natural History, between the astronomers Harlow Shapley and Heber Curtis. It concerned the nature of so-called spiral nebulae and the size of the universe; Shapley believed that distant nebulae were relatively small and lay within the outskirts of Earth's home galaxy, while Curtis held that they were in fact independent galaxies, implying that they were exceedingly large and distant.
The two scientists first presented independent technical papers about "The Scale of the Universe" during the day and then took part in a joint discussion that evening. Much of the lore of the Great Debate grew out of two papers published by Shapley and by Curtis in the May 1921 issue of the Bulletin of the National Research Council. The published papers each included counter arguments to the position advocated by the other scientist at the 1920 meeting.
In the aftermath of the public debate, scientists have been able to verify individual pieces of evidence from both astronomers, but on the main point of the existence of other galaxies, Curtis has been proven correct.

Obama's figure is the best example of his vision of the American dream, as he came from a humble family and became the first Afro-American president of the USA.
He highlights the opportunity, considering that all citizens should have equal rights and be able to get rich and successful. The most important thing is to give an opportunity to everybody.
To achieve the American dream society should create equal opportunities for everyone, people should open to each other and appreciate cooperative efforts rather than individual efforts.
The main reason why the Germans followed Hitler is because he was a strong and charismatic leader that identified with the humiliation Germany felt after World War I. People were eager to elect someone who would "take charge" and usher in a new era of German dominance and pride.
