Section VIII: The Development of Modern Science
Tycho Brahe (1546-1601), a Dane, spent nearly his entire life making careful measurements of the positions of the stars and planets. Most of his work was done at Copenhagen under the patronage of the Danish king. He developed and refined astronomical instruments to an accuracy that was far superior to anything previously done. In his late years at Prague, he started on the reduction to order of the systematic observations that he had made over a period of decades. In 1600 a young German mathematician and astronomer, Johannes Kepler (1571-1630), visited Tycho and then stayed to help in the mammoth …

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]

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 …

Section VIII: The Development of Modern Science
Isaac Newton (1642-1727) was born and educated in England. He attended Trinity College, Cambridge, and there found the inspiration for his prodigious work that was to synthesize and extend the labors of Copernicus, Galileo, Kepler, and others beyond the wildest dreams of any of them. Newton was the intellectual giant who set the direction of the physical sciences on the paths they were to follow undeviatingly into the twentieth century. [excerpt]

Section XX: Meaning in the Physical Sciences
The twentieth century has seen two major revolutions in our theories of physics concerning nature, and these have made us change many of our concepts about the terms in which nature can be described. The new theories born in these revolutions are the theory of relativity and of quantum mechanics. The biological sciences had their revolutions in the nineteenth century, and while remarkable progress has been made since, nothing comparable to that upheaval has occurred in this century. Of the two massive changes in the concepts of the physical sciences, we can discuss but one here. [excerpt]

Section XX: Meaning in the Physical Sciences
Newton's laws of motion and their associated definitions encountered their first difficulty near the middle of the nineteenth century.
Newton had designed his theory to describe the behavior of matter in space and time by inventing a relationship between the force on a body and the resulting change in motion of the body. Such a description of nature came to be called mechanical, and a large part of physicists' efforts were directed toward reducing all aspects of physics to mechanics. These efforts were rewarded magnificently in the fields of heat, electricity, and sound, in addition to astronomy and other more …

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.

Section XIV: The Industrial Revolution, Classical Economics, and Economic Liberalism
While capitalism was making rapid strides toward dominating English industry, changes were taking place in agriculture which made it more efficient and productive, and which prepared it to be fitted eventually into the industrial capitalistic pattern. Actually, changes in the direction had been occurring in English agriculture since the revival of trade discussed in earlier chapters. [excerpt]
