Notes 2

3 Requirements for a new technology:

-A new concept

-Technological capability

-Individual/social/political will power


Technology throughout history
    -Stone Age- when people first started using tools and using fire. These tools were rudimentary and often simply based on readily available materials, such as wood, stone, flint and animal products.  The stone age represented the earliest evidence of people using tools. We mark its end with the earliest use of metals. This period runs from prehistoric times until about 2000 b.c.  Some significant advances of the stone age include:
-the first fire-making techniques and machines
- the first use of fire  
-the earliest cooking tools 
-early stone weapons including spears, bows and arrows
-stone knives and saws
-early stone and wood musical instruments

    -Bronze Age- the Bronze Age marked the first discovery and use of metals. Tin and copper were used to make bronze which was used to fashion tools. This period runs form about 3000 b.c. to about 1000 b.c. ,although the prevalence of metallurgy varies significantly (by hundreds, if not thousands of years) from one geographical area to the next.   Some significant advances of the bronze age include:
-swords
-horse drawn carriages
-the crossbow
-irrigation
-early drills

    -Iron Age- Iron is first discovered and replaces bronze as the primary material for making weapons and tools. This time period runs from about 1000bc. to about 500 a.d., although, again there is some significant variation between different regions with regard to technology. With the coming of iron comes much more widespread use of metals, as iron was stronger and more practical than bronze for most applications.  Some significant advances of the iron age include:  
-many farming implements including plows
-armor
-better knives, swords, axes etc.
-coins for money

    -Middle Ages- The Middle Ages began after the fall of the Roman Empire and lasted nearly a millennium. From the beginning to the middle of this time period, there is very little technological advance in the West.  The end of the middle ages are often marked by the invention of the printing press.
 
   -Renaissance-The Renaissance was a time of "rebirth". The printing press and other related technologies helped increase communication and the sharing of ideas. The Church played a less pronounced role limiting social and scientific discourse. Science and technology flourished, bringing many new inventions and ideas Some significant advances of the renaissance include:
-The water mill
-The wind mill
-The hour glass
-eye glasses
-the spinning wheel
-the printing press
-the mechanical clock
-the pendulum
-flushing toilets
-gunpowder
 -Industrial Revolution- The industrial revolution brought the birth of modern manufacturing. There were two inventions/discoveries that helped bring on the modern era of technology, electricity and the combustion engine, but thousands of other inventions and innovations that helped define the times. Inventions and industries that were central to the industrial revolution include:
-external, then internal combustion engines
-electricity
-the telegraph, the telephone
-the textile industry- mills, factory work
-the power loom
-efficient steel-making
-the steam engine- steam powered trains, boats and machines


    -Information Age- Our current age is referred to as the information age. Since the 1980s with the advent of personal computing and cellular technology, western society has been characterized by high tech communication devices.  The three primary technologies associated with the information age are the computer, the internet and cellular communication, but there are thousands of others.
