History is the systematic study of history. All the major events occurring in human history since the beginning of time are categorized as history. Events taking place before the invention of written language are regarded as prehistorical. “history” is now an umbrella term that includes the collective memory, research, documentation, discovery, compilation, arrangement, presentation, and explanation of data about these major events. As such, history has a clear chapter structure with a beginning, middle, and end.
Historians make use of various methods in order to classify past events into a set of chapters, which form an ongoing history. Most historians fall under two general categories: political scientists who conduct research for the sake of understanding history; and anthropologists who study the physical remains of past events, or anthropology. While political scientists frequently write in a political manner, anthropologists generally write in a more casual way that leaves their readers with a good idea of what the author was thinking at the time.
One of the most influential historians of the last century was Theodore Adelson. He was born and grew up in Brooklyn, New York City. When he was five years old, his family immigrated to Great Britain. In addition to being a keen student, Theodore also became a great sportsman, known to be a gentle, caring, generous, and compassionate person. He earned a bachelor’s degree in mathematics at Harvard University, a master’s degree in physics from Cambridge University, a doctorate in physics from Harvard University, and a doctoral degree in mathematics from Cambridge University in Cambridge, Massachusetts.
