smelting its own copper, alloying with
Tin or trading for it.
 The Rise of Civilizations
◦ Ancient Egypt
◦ Ancient Rome/Greece
◦ Chinese Dynasty
◦ Ancient Mayans

7.  Mankind had perfected the art of
crafting stone structures
 From Pyramids to Stone Coliseums
 Using metal to reinforce weapons,
early transportation

8. Seven Wonders of the
World consists of:
The Great Pyramid of
Giza (the most ancient as
well as the only surviving
structure), the Hanging
Gardens of Babylon,
the Temple of Artemis at

Halicarnassus,
the Colossus of Rhodes,
and the Lighthouse of
Alexandria.

9. Iron Age
 1200 BC – 400 AD
 Known for improvements with humans
working with metals and forming better and
improved weapons: (i.e. swords, daggers
as well as better farming equipment)

10. The Separation of the Iron Age to
the 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.

11. Pre-Scientific Age
 400~ AD – 1500~ AD
 Think 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

12. Industrial Age
 1750s- 1820s~1840s
 Now we are getting to the good stuff.

13. Poor Working Conditions

14. Second Industrial Revolution
 1860s~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 Radio
 Maritime Surge: Screw Propeller, oscillating
engine, iron steamboat, surface condenser, paddle
wheel and ironclad battleships.

15. Atomic Age
(1945~1954)

the first
atomic bomb
and
 the Red
Scare/
McCarthyism
(1947-1954)

16. Space Age
(1957~)

17. Information Age
 Also known as the Digital Revolution,
Computer Age, Digital Age
 Late 1970s to the present
 It is the change
from analog, mechanical,
and electronic technology to digital
technology

18. The Future?
 Robotics
 Electrical
 Bioengineering
