According to Merriam-Webster, a hero is defined as “exhibitionist or characterized by courage and daring” or a person who is “extremely noble or selfless,” meaning he or she does not have to be a superhero to be considered heroic. Doing something that has a significant effect on society or changing the way something seems to be makes one heroic; therefore, Albert Einstein is heroic in numerous ways. Throughout his life, Albert Einstein accomplished many extraordinary things that impact people today. For example, in 1905, “often called Einstein's “miracle year,” he published four papers in the Annalen der Physik, each of which would change the course of modern physics” (Michio, Kaku 13). In Einstein's four books, he “applied quantum theory to light to explain the photoelectric effect, offered the first experimental proof of the existence of atoms, expounded the mathematical theory of special relativity, and demonstrated the first mechanism to explain energy. source of the Sun and other stars” (13). During 1905-1915 Einstein began to realize that his theory of relativity was flawed, because it “made no mention of gravitation or acceleration” (19). “In November 1915 Einstein finally completed the general theory of reality” (20); “in 1921 he won the Nobel Prize for physics” (Belanger, Craig. 1). Albert Einstein began studying the motion of particles, which led to “the hypothesis that matter is composed of atoms” (“Albert Einstein” 2). This prompted Einstein to begin studying Brownian motion and explained why “the motion of pollen grains increased as the temperature increased but decreased if larger particles were used” (“Albert Einstein.”2). His reasoning was explained "as... half of the paper... a contribution to developing and successfully carrying out the general theories of relativity, with a lasting effect on science. In conclusion, Albert Einstein is noble because he did many things that have shaped science as it is today, such as developing and finalizing the theory of relativity and light and the hypothesis that matter is composed of atoms. Without Albert Einstein we would not be where we are today work and his achievements. Works CitedRM, plc. “Albert Einstein” Biographical Database (2011): 1. Historical Reference Center. 1 May 2014.
