Hominids started using primitive stone tools millions of years ago. The earliest stone tools were little more than a fractured rock, but approximately 75, years ago,  pressure flaking provided a way to make much finer work.
Bison had yielded to cattle; mountains had been blasted and bored. Great swaths of land that had once whispered grass now screamed corn and wheat. Nation-states had conquered Indian peoples, slaughtering some of them and confining and controlling most of them.
Population had increased across much of this vast region, and there were growing cities along its edges. A land that had once run largely north-south now ran east-west. Each change could have been traced back to the railroads. These changes mutually fueled the Second Industrial Revolution which peaked between and The need Technological advancements of the 1960s massive industry was obvious: Questions abounded about the character this new American territory would take: Still, others believed the technological innovations of the Second Industrial Revolution was the unstoppable culmination of modern civilization propelling the fulfillment of Manifest Destiny.
Questions of this nature were not new in American history.
Throughout the first half of the nineteenth century, Americans were forced to adjust to the implications of the First Industrial Revolution.
After the invention of steam power and the cotton gin by Eli Whitney incotton could be shipped from the American South by New England ships to the vast textile factories of Great Britain, producing a reverse triangle trade around a single global commodity.
The following maps demonstrate the advancement of the railroad before the Civil War as always, click to enlarge image: Railroad Map, 19th Century. The Second Industrial Revolution took local communities and their new products out of the shadow of large regional agricultural based economies which was assisted by new labor forces and production techniques.
During the Second Industrial Revolution, innovations in transportation, such as roads, steamboats, the Eerie Canal, and most notably railroads, linked distant, previously isolated communities together.
Transporting Products For the first time, goods from the American interior could be shipped directly to the Atlantic, and vice versa.
Being able to ship products great distances transformed the nature of economic activity in the United States. Before the development of this elaborate transportation and communication system, economies were localized and often based on a barter system.
The transportation revolution opened up new markets for farmers, industrialists, and bankers who could now bring crops cotton in the Mississippi River Valley, wheat in the Midwest, and manufactured goods in upstate New York into a global market based on credit. Government Involvement The federal government actively participated in this growth by promoting industrial and agricultural development.
High tariffs were enacted to protect American industry from foreign competition, land was granted to railroad companies to encourage construction, and the army was employed to forcibly remove Indians from western land desired by farmers and mining companies.
The rapid growth of factory production, mining, and railroad construction all boosted the new industrial economy and stood in stark contrast to the previous small farm and artisan workshop economy of the pre-Civil War era.
The living standards and the purchasing power of money increased rapidly, as new technologies played an ever-increasing role in the daily lives of working- and middle-class citizens. Between andalmost 11 million Americans moved from farm to city, and another 25 million immigrants arrived from overseas.
Byfor the first time in American history, the census revealed more people lived in cities than on farms.

Meet people as they travel for work and pleasure, and as they move to new homes. Life expectancy has increased rapidly since the Enlightenment.
Estimates suggest that in a pre-modern, poor world, life expectancy was around 30 years in all regions of the world. In the early 19th century, life expectancy started to increase in the early industrialized countries while it stayed low in the rest of the world.
This led to a very high inequality in how health was distributed. The IT revolution drives the extraordinarily rapid decline in the cost and rapid increase in the processing power of digital technologies. The digital device whose technological advance has perhaps been most crucial to the IT revolution is the microprocessor, the collections of millions of tiny circuits that serve as the “brains” of personal computers and that are embedded in an ever.
