Before the 1400s: Books were handwritten (manuscripts), time-consuming, and expensive, making them very rare.
Johannes Gutenberg: Invented the moveable type printing press in the mid-1400s.
Process: Individual metal letters were placed in a frame to form words, coated with ink, and pressed onto paper. The first book printed was the Gutenberg Bible.
Spread: By 1500, printing presses were operating in every major European city.
Impact and Contribution to Historical Change
Cheaper and Quicker: Printed books were far less expensive and faster to produce.
Increased Literacy: More people learned to read and write, leading to widespread reading and the introduction of new ideas.
Decline of Church Control: The Catholic Church’s control over learning and ideas weakened.
Rise of Vernacular: Books were published in native languages, not just Latin.
Renaissance Spread: The printing press was crucial in spreading Renaissance ideas across Europe.
Advances in Navigation
Before the Age of Exploration: Sailors stayed close to shorelines.
New Maps: Cartographers used detailed maps from Constantinople and developed portolan charts to map coastlines, harbors, currents, tides, and depths accurately.
New Equipment
Quadrant and Astrolabe: Used to determine a ship’s latitude.
Compass: Located north and identified direction.
Log and Line: Measured a ship’s speed in knots.
Line and Lead Weight: Measured water depth to ensure safe sailing.
Logbook: Captains recorded travel information regularly.
New Ship Innovations
Caravel: Large, sturdy ships with triangular lateen sails for better maneuverability.
Carvel-Built Hulls: Planks fitted edge to edge, making ships lighter and larger.
Rudder: Improved steering.
Castle: At the back of the deck, provided lookout and defensive area.
Impact and Contribution to Historical Change
Accurate Navigation: Allowed sailors to determine their exact location and make long voyages safer.
Exploration and Colonization: Enabled European exploration, conquest, and colonization of the Americas and beyond.
World War II
Improved Submarines and Torpedoes: Research into sonar (ASDIC) and radar.
Aircraft Carriers: Mobile airbases at sea.
Tanks: Development of Panzer tanks, dummy tanks, and amphibious tanks.
Weapons: Improved grenades, pistols, rifles, and machine guns, like the MG 42.
In the Air
Aircraft: British Hurricane and Spitfire, US B-29 Superfortress, and Luftwaffe
Manhattan Project: US research program developing the atomic bomb, used on Hiroshima and Nagasaki in 1945.
Impact and Contribution to Historical Change
Mobile Warfare: Technology allowed rapid movement and more extensive destruction.
Civilian Impact: Increased civilian casualties and city destruction.
Cold War Tensions: The atomic bomb threat loomed over US-Soviet relations.
