Answer:
The differences include:
Japanese feudalism wasn’t based on hierarchy while the European was based on hierarchy.
The Japanese system was based on Chinese Confucian law and Buddhism while the European system was based on Roman and Germanic law.
The similarities is that the two systems causes series of war fare and societal unrest.
<span>The change came before World War Two rather than after the War. President Roosevelt and his advisors concluded that the United States needed to become involved in foreign affairs in both the Atlantic and the Pacific theaters. In the Atlantic sector, the key blow was the fall of France. This meant that the only anti-Nazi power in Europe was Britain. Even though Britain managed to weather the first great crisis, the Battle of Britain, Prime Minister Churchill knew that the British could not go on without help. The British simply could not maintain sufficient manufacturing, especially of big capital projects, without assistance. </span>
The correct answer is: "He developed mathematical principles"
René Descartes (1596 – 1650) was a French philosopher, mathematician, and scientist who lived more than 20 years in the Dutch Republic and was one of the main figures of the Dutch Golden Age.
His great influence in mathematics has been his major contribution to the Scientific Revolution, although his work in philosophy is outstanding too. He developed the the Cartesian system of coordinates. He is considered the father of analytical geometry, which connects both algebra and geometry and which has been used in the development of infinitesimal analysis and calculus .
Ladd-Franklin's mathematical interests ultimately led her to make important contributions to the field of psychology. In 1886, she became interested in the geometrical relationship between binocular vision and points in space and published a paper on this topic in the first volume of the American Journal of Psychology the following year. During the 1891-92 academic year, Ladd-Franklin took advantage of her husband's sabbatical leave from Johns Hopkins and traveled to Europe to conduct research in color vision in the laboratories of George Müller (1850-1934) in Göttingen, and Herman von Helmholtz (1821-1894) in Berlin, where she also attended lectures by Arthur König. In contrast to the prevailing three-color and opponent-color explanations of color vision, Ladd-Franklin developed an evolutionary theory that posited three stages in the development of color vision. Presenting her work at the International Congress of Psychology in London in 1892, she argued that black-white vision was the most primitive stage, since it occurs under the greatest variety of conditions, including under very low illumination and at the extreme edges of the visual field. The color white, she theorized, later became differentiated into blue and yellow, with yellow ultimately differentiated into red-green vision. Ladd-Franklin's theory was well-received and remained influential for some years, and its emphasis on evolution is still valid today.
