Stone Age

<Paleolithic-Mesolithic-Neolithic>

Hunters and Gathers“Old Stone Age”, “Prehistory”,

The Separation of the Iron Age tothe Pre Scientific Age One thousand years ago,

superstition and the sword ruled.It was a time of darkness. It was a world of fear.

At this time mankind was choosing to not believe in myth and magic and scientific reasoning was beginning to set in.

Pre-Scientific Age400~ AD – 1500~ ADThink medieval times, with bows and

arrows, trebuchet/catapults and siege engines. Featuring guillitines and broader studies into the sciences of electricity, machinery and chemistry.

Let’s call this a Prelude to Steampunk

Poor Working Conditions

Second Industrial Revolution1860s~1914~  It is considered to have begun around the

time of the introduction of Bessemer steel in the 1860s and culminated in early factory electrification, mass production and the production line.

Also Railroads, highways, steam power, oil power

Telegraph, telephone and RadioMaritime Surge: Screw Propeller, oscillating

engine, iron steamboat, surface condenser, paddle wheel and ironclad battleships.

Atomic Age(1945~1954)Dropping

of the first atomic bomb and

the Red Scare/ McCarthyism (1947-1954)

Space Age(1957~)

Information AgeAlso known as the Digital

Revolution, Computer Age, Digital Age

Late 1970s to the present It is the change from analog,
