who was one of the first to chart the course of forgetting over time
Hermann Ebbinghaus
title: Forgetting text: measures forgetting by the amount of training required to reach the previous level of performance. German psychologist Hermann Ebbinghaus (1885) used this method on himself. He memorized lists of nonsensical syllables until he could repeat the list two times without error. After a certain interval, he relearned the list and saw how long it would take him to do this task. If it took fewer times, then there had been less forgetting. His experiment was one of the first to study forgetting. For this type of measurement, a participant has to identify material that was previously learned. The participant is title: Hermann Ebbinghaus text: Hermann Ebbinghaus Hermann Ebbinghaus (January 24, 1850 – February 26, 1909) was a German psychologist who pioneered the experimental study of memory, and is known for his discovery of the forgetting curve and the spacing effect. He was also the first person to describe the learning curve. He was the father of the eminent neo-Kantian philosopher Julius Ebbinghaus. Ebbinghaus was born in Barmen, in the Rhine Province of the Kingdom of Prussia, as the son of a wealthy merchant, Carl Ebbinghaus. Little is known about his infancy except that he was brought up in the Lutheran faith and was a title: Forgetting text: German psychologist Hermann Ebbinghaus (1885). Using himself as the sole subject in his experiment, he memorized lists of three letter nonsense syllable words—two consonants and one vowel in the middle. He then measured his own capacity to relearn a given list of words after a variety of given time period. He found that forgetting occurs in a systematic manner, beginning rapidly and then leveling off. Although his methods were primitive, his basic premises have held true today and have been reaffirmed by more methodologically sound methods. The Ebbinghaus "forgetting curve" is the name of his results which he plotted out title: A Brief History of Time text: circles, because of "mystical reasons". Second-century Greek astronomer Ptolemy also pondered the positions of the sun and stars in the universe and made a planetary model that described Aristotle's thinking in more detail. Today, it is known that the opposite is true: the earth goes around the sun. The Aristotelian and Ptolemaic ideas about the position of the stars and sun were disproved in 1609. The first person to present a detailed arguments that the earth revolves around the sun was the Polish priest Nicholas Copernicus, in 1514. Nearly a century later, Galileo Galilei, an Italian scientist, and Johannes Kepler, title: Time travel text: en fût jamais" (1770) by Louis-Sébastien Mercier, "Rip Van Winkle" (1819) by Washington Irving, "Looking Backward" (1888) by Edward Bellamy, and "When the Sleeper Awakes" (1899) by H.G. Wells. Prolonged sleep, like the more familiar time machine, is used as a means of time travel in these stories. The earliest work about backwards time travel is uncertain. Samuel Madden's "Memoirs of the Twentieth Century" (1733) is a series of letters from British ambassadors in 1997 and 1998 to diplomats in the past, conveying the political and religious conditions of the future.
