Pacey, Gunpowder as a tool of empires: 1450-1700 Background | argument | case | orgins & use of ballistics | dates | conclusion Background: how the authors sustain one another's arguments?
Asia and the slow diffusion of technical systems westward thanks to the Arabs. Technical advances in "seeing," conceptualizing, and painting the world. Content: 2. Voyages of trade & rediscovery 1400-1790, ships are a small example of a tool complex because of the necessity of timber, pitch, tar, ropes, pulleys, fine technology [in the shape of compasses, sextants and logs] barrels, rigging and sails.
What good is gunpowder without a means of delivery to a target? Ballistics was based on the practice and then knowledge of aiming artillery, later based on algebra before calculus was common in the 1680s and 1690s. Dates and sounds Key dates & words: 1150 use of explosive powder technology transfer east to west
New concepts: • Geometry of projectiles formed a parabolic path • Although heavy guns were often fired for maximum destructive effect at point blank range (with the barrel horizontal), greater range could be achieved by elevating the gun. Quadrants, sights and levels enabled the gunner to set the barrel at specified elevations. • The question of determining the correct elevation necessary to fire a shot a given distance (and its inverse, the prediction of range at a given elevation) was the most taxing problem of gunnery as a mathematical art. • Tartaglia set the terms of the debate by seeking to portray the geometry of a projectile's trajectory based on the opposed natural and violent motions of Aristotelian physics. His work provided the basis for many subsequent accounts in textbooks and manuals. • Galileo offered a new foundation in his Discorsi of 1638, demonstrating the parabolic path of projectiles and reinforcing the military relevance of his work with a complete table of ranges. • timeline as a measure of growing precision, performance and rates of diffusion for new inventions. • absolute necessity of a dialogue in technology transfer • blocks in technological innovation due to any of the three aspects or spheres
In the following chapter, as a consequence of guns, Pacey notes that: • regimentation and manufacture arose side by side as a synergistic process where the means to a strategic outcome depended on techniques and not merely possession of superior tools.
• The standardization of space in that artists and ballistics used a similar rationale:
These new tools and techniques coincided with the rise of: secularism, commercialism, rationalism, mechanization, atomistic philosophy produced such tensions in the agrarian based power structure of the Middle Ages and feudalism that a new order emerged in the cities of Italy, Flanders, and the Netherlands that was to challenge both the church and military power based in part on what sectors could acquire the new tools and with sufficient skills to employ them in commerce and warfare.
It was at once a war of liberation and a revolution in authority furthered by a technological sophistication of immense proportions.
This innovative process is called “the great titration!”
The great titration
List the contributions of each center of cultural diffusion:
titrate: to test a known mass by measuring volumetrically the precise amounts of different substances contributing bulk to a compound substance. The purpose of this titration is to measure the exact amount of a solution needed to produce a certain reaction. i.e. ammonium nitrate (fertilizer ) needed to create an explosive device (bomb).
"In one instance after another in Europe at this time, we find people analyzing how individual machines were operated, including musket's, surveying equipment, and spinning wheels."
