1. Greek And Medieval Science, Robert L. Bloom, Basil L. Crapster, Harold A. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section VIII: The Development of Modern Science

What kind of questions did the Greeks ask themselves about the physical universe? We can paraphrase Plato: the stars move about the earth in circles, the perfect paths, and they move with uniform motion as befits divine and eternal beings. But five of these stars are planets (Greek for wanderers) which appear to have irregular motion, first moving forward, then actually stopping, and then moving backward for awhile. Since the heavens are incorruptible, the planets too must really be moving in uniform motion in circular paths. How then can we account for the apparently irregular motions? What uniform motions must …

4. Social Darwinism, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section XV: Biology and the Rise of the Social Sciences

The singular impact of Darwin in fields other than biology can be attributed largely to one man, Herbert Spencer (1820- 1903). It was Spencer, not Darwin, who coined the expression "survival of the fittest." Although neglected today except by historians of the nineteenth century thought, Spencer's influence on his own time was so great that Justice Oliver Wendell Holmes was able to wonder if "any writer of English except Darwin has done so much to affect our whole way of thinking about the universe." Herbert Spencer was born into a traditionally nonconformist English family of modest means. He refused a …

3. The Second Industrial Revolution, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section XIV: The Industrial Revolution, Classical Economics, and Economic Liberalism

There is abundant evidence for the opinion that after about 1850 the Industrial Revolution entered upon a new phase in its development. Inventions occurred at a more rapid pace than ever before in history. (Between 1850 and 1914 there were more than fifty times as many patents issued in the Unites States as during the preceding sixty years.) Increasingly these inventions were the work of scientists and engineers working in the research laboratory rather than of self-taught craftsmen, as had often been the case in the eighteenth century.

1. Charles Darwin And Organic Evolution, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section XV: Biology and the Rise of the Social Sciences

Evolution was not a new idea. The Greeks speculated on it. In the century before Darwin many different evolutionary theories were proposed, among them notable efforts by Buffon, Lamarck, and Goethe. Their common thread was the concept that the succession of biological changes in geological time represented a fact, if not a natural law. The stumbling block was for all of them, as it had been for Cuvier, the concept of fixed species, which clashed with the vision of a distant past populated with races of plants and animals now extinct. It became evident that the idea of fixed species …

5. Social Darwinism Reconsidered, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section XV: Biology and the Rise of the Social Sciences

Although the contemporary reaction to the implications of evolution was generally one of long-term optimism, an antithetical reaction did exist. Seen in stark terms, evolutionary theories were depressing to those who, on religious or humanitarian grounds, found the reduction of life to an irrational and brutal struggle for existence disturbing and provocative. There was, however, an important body of thought which accepted Darwin's findings without embracing the social or ethical implications of Social Darwinism. Many who studied Darwin came to the conclusion that it was possible to concede that man is an animal, but an animal capable of moral and …

2. The Theory Of Special Relativity, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section XX: Meaning in the Physical Sciences

Albert Einstein (1879-1955) published his first work on relativity in 1905, the same year in which he published remarkable papers on Brownian motion and the photoelectric effect. At the time he did this work, he was a patent examiner in the Swiss Patent Office. He was awarded the Nobel Prize for physics in 1921 "for his services to the theory of physics, and especially for his discovery of the law of the photoelectric effect." He became a professor of physics at several German universities, and in 1916, he took a position at the Kaiser Wilhelm Institute in Berlin.

As the …

2. Copernicus, Robert L. Bloom, Basil L. Crapster, Harold A. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section VIII: The Development of Modern Science

Nicolaus Copernicus (1473-1543), of German and possibly Polish extraction, spent three years at the University of Cracow and then ten years at Italian universities. In Italy he was introduced to the Pythagorean ideas, which left a permanent mark on his mind, and became interested in astronomical theories. He returned home to the position of canon of Frauenburg cathedral where he stayed until his death. [excerpt]

4. Roger Bacon And Medieval Science, Robert L. Bloom, Basil L. Crapster, Harold A. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section IV: The Medieval Ferment

Throughout the Middle Ages there was little interest in theoretical science as such. Not since the Greeks had nature been considered a sufficient object in and of itself for most of the study that we would call scientific. The Middle Ages ' concern with nature was not its primary concern. The medievalist was interested in nature either as a mirror of the supernatural or as something which could be used in reaching the supernatural. The reappearance of Aristotle's thought and the development of those practical and technical interests which grew up around the problems of trade and industry demanded a …
