Movement & Geography
Time, Distance, Communication & Movement[edit | edit source]
- time measure by distance
- defined by geography & distances
- technological advance is to overcome barriers to movement of geography and distance
Forms of Human Movement[edit | edit source]
- walking / running
- Greece: marathona
- Inca runners served to communicate across empire
- water
- currents
- paddle/ oars
- sail
- animal propulsion
- domestication of animals for transport
- mechanized propulsion
Animal Propulsion[edit | edit source]
- horses
- prior to domestication horses were hunted for food
- cattle
- camels
- ability to cross large distances with heavy loads (25-30 miles / day)
- ability to survive distances without water
- related to metabolism and not the "hump" which is made of fat and provides energy (food) and not water
- ability to withstand absence of water related to conserve water and to adjust its body temperature in order to avoid sweating
- originally from the Americas: related to the Llama
- sources:
- migrated to Asia where they were domesticated in central Asia
- camels to Arabia
- camels to Nile and Sahara/ Sub-Sahara Africa
- horses
Human-Powered Boats[edit | edit source]
- easiest movement by boats designed to flow with the current
- Babylonian inflatable boats made of animal skin/ guts
- oars, paddles, etc.
- review various forms
- Polynesian canoes and catamarans
Sail[edit | edit source]
- wind propulsion
- Egypt
Mechanized Transportation[edit | edit source]
- revolution in distance and time
- cultural diffusion accelerated
- steamboats
- prior to steam boats, the Mississippi River provided transportation in one direction only, downstream. With steam, boats could journy upstream, which allowed for trade to flow both norht and south.
- railroads caused need for time zones
- before the need to create regular schedules across great distances, time was measured locally by the position of the sun
- with rapid movement by rail, the need for a comman, relative measurement of time became important in order to organize the rail system and its schedules: time zones were the solution, creating a single period of time across a large distance that could be calibrated against other time "zones"
- local rail / trolleys
- automobiles
- trucks
- airplanes
Communication & Time, Space & Distance[edit | edit source]
- communication across distance was a function of movement
- writing revolutionizes time by bringing distances together through communication across distance
- with new forms of transportation, communication was speeded over time (horse, boat, sail, railroad, airplane, etc)
- modern communications revoluation
- speed of correspondences measured by distance (letter-writing)
- telegraph revolutionizes abiltity to send messagaes over distance instaneously
- trans-Atlantic cable
- origins of the Associated Press
- Morse Code
- photographs transmitted by telegraph
- trans-Atlantic cable
- telephone
- transmission of voice over distance (still using wires)
- radio
- transmission of voice or code over distance without wires
- television
- transmission of moving or live images over distance without wires
- facsimile machines
- ability to send copies of documents over telephone lines
- cellular phones
- more practical than radio
- internet
