Summary: Technology Early


 Page 1:  Technology as Inspired Invention
 The medieval printing press is key to spreading ideas that lead to American independence, while advancing technology leads to the smartphone

 Page 2:  Ancient Technology
 Humans know how to control fire from the very beginning, then do on to develop the bow-and-arrow as their first important invention, before learning to make hard metals

 Page 3:  Medieval Inventions
 For 2,500 years after the Bronze Age, humans develop increasingly sophisticated stonework, but make few other important breakthroughs outside of weaponry

 Page 4:  Medieval Technology
 By the medieval period, iron-working forges are being used in early businesses, but with little effect on ordinary life, until the invention of the printing press changes everything

 Page 5:  Primitive American Tools
 Colonial settlers use axes, and other tools with metal blades, but fashion almost everything else they need from wood or cast iron

 Page 6:  Colonial Farming
 Colonial families spend most of their energy enlarging their simple dwellings, and farming small surrounding fields, while developing a surprising variety of wooden tools

 Page 7:  Iron and Blacksmiths
 Iron-working technology is slow, tedious and small-scale, using charcoal as the primary fuel, fanned with leather bellows to achieve the high temperatures required

 Page 8:  Homespun Fabric
 Few colonists can afford fabric imported from Britain, so most spin wool from sheep, or fiber from flax, to produce a course yarn, which is woven into cloth on wooden looms

 Page 9:  Colonial Printing Press
 Benjamin Franklin makes his fortune running a print shop, using a press that is little different from the one Gutenberg used to print his first bible, 300 years previously

 Page 10:  Waterpower
 In colonial America, the only sources of power are animals and waterwheels, the latter being used to drive sawmills and grist mills, while wagons are scarce

 Page 11:  Textiles and Cotton
 Free from British rule, former colonists copy British designs for spinning equipment, set up the country's first mills, and invent the cotton gin

 Page 12:  Steam Power
 Steam engines can be used anywhere, but are first adapted to power vessels, then early locomotives, while canals prove wildly successful

 Page 13:  Age of Sail
 Even as steamboats are appearing everywhere, great sailing ships are just entering their prime, as graceful clippers round the world, and whalers probe Arctic waters

 Page 14:  Animals on the Farm
 Steam engines are driving industrial equipment in greater numbers, while farmers still rely on the horse, and mechanical reapers make haying easier for the biggest farmers

 Page 15:  Blast Furnaces and Coal Trains
 As railroads open up Pennsylvania coalfields, iron production surges on newly cheap and abundant coal, while rolling mills produce wrought iron used to make industrial equipment

 Page 16:  Machines to Make Machines
 Machinery is assembled from many separate parts, which must each be formed into particular shapes, but tools to create these shapes out of iron are still rudimentary

 Page 17:  Steam Engines Get Bigger
 Early steam engines are so big and bulky that they are only useful on vessels, but gradual improvements allow for more compact engines used to power machinery

 Page 18:  Locomotives and Wagons
 American expansion is propelled locomotives, which still burn wood to produce the steam, while urban transportation remains firmly based on the horse-drawn wagon

 Page 19:  Iron-working Machines
 As the industrial revolution gears up, tools required to make machinery quickly transition from wood to cast-iron frames, for increased rigidity, allowing greater precision

 Page 20:  Big Tooling, from Catalogs
 As machines become bigger and more advanced, equipment wholesalers offer printed catalogs, allowing distant customers to order the latest machinery

 Page 21:  The Milling Machine
 The milling machine is a major breakthrough, being far more versatile for making complicated metal parts than earlier single-purpose tooling, and offering an expanded range of operations

 Page 22:  Rapid Industrial Transformation
 In just 80 years, America grows from a simple supplier of raw materials into a powerful industrialized society, based on abundant iron, coal and steam power
