Secrets of the Deep Sky
As a digression, historians and philosophers of science have many times remarked on the ubiquitous, perhaps even necessary, element of public advocacy (or even propaganda) that is necessary for a controversial view to gain acceptance. One can go further and note that one of the problems in science is that there is, and always has been, a whole lot of fudging going on theory is routinely defended by selective use, presentation, collection, and manipulation of the evidence, ignoring some facts and stressing others, redefining terms, and retrospectively and conveniently reinterpreting data. This cannot be justified formally, but it in many classic cases was necessary, in the face of imperfect data or measurement (or understanding), in order to reach a general understanding of things. Gregor Mendel's supposed cheating in his analysis of pea plants is a famous example (Weiss 2002b), and so it was with the classical Copernican revolution in astronomy that occurred despite many totally wrong...
The readers of books extend or concentrate a function common to us all. Reading letters on a page is only one of its many guises. The astronomer reading a map of stars that no longer exist the Japanese architect reading the land on which a house is to be built so as to guard it from
The Incas occupied the highlands along the west coast of what is now Peru. The Mayan culture occupied the Yucatan Peninsula and surrounding areas of Central America, and the Aztecs controlled the central plateaus of Central America. When Columbus, Cortez, and their compatriots arrived in the new world, the Meso-American cultures were exposed to several devastating diseases, including measles, smallpox, and chickenpox, which were more lethal than the military armaments the invaders brought. The Pre-Columbian Americans still lived in a Stone Age culture, but were highly sophisticated in their knowledge of mathematics, astronomy, and language. Among the most useful drugs discovered in the New World was the Cinchona bark (quinine), which was used to treat fevers, including malaria. Diseases were believed to be caused by supernatural, magical, and natural causes. Treatment was related to the cause (56). One of the sources of information about disease in Pre-Columbian...
Galileo is mainly known for his physics and astronomy but in other ways he was the first modern scientist, advancing from the greats like Aristotle by the use of controlled experiments, newly invented instruments and a more critical approach to relating theory to observation. In his treatise on the philosophy of knowledge, The Assayer (Galilei 1622), Galileo gave a rather perceptive explanation of taste and smell particles from the detected object wafted on air to the tongue and nose, where, after mixing with water and mucus on the tongue and nasal membranes, they were detected. The outer part of the body was assumed to be insensitive to such small
