Study Notes
The Telegraph and Its Impact
- The telegraph, developed in the 1840s, revolutionized communication by sending electric signals across wires.
- Samuel Morse, who began work on the telegraph in the 1830s and developed Morse Code, was key in its establishment despite competition from numerous claimants.
- The initial telegraph offer to the U.S. government was rejected, but in 1843, Morse secured Congressional funding for a system linking Washington, D.C., to Baltimore.
- The first long-distance message, sent on May 24, 1844, was "What hath God wrought?"
- By 1861, Western Union completed the first transcontinental telegraph line, highlighting the speed and reach of this communication method.
- The 1858 transatlantic cable allowed near-instant communication between the U.S. and Europe, altering global relations and business.
- The telegraph's expansion led to Western Union's value skyrocketing by 11,000 percent between 1857 and 1867, with a network of about 100,000 miles by 1866.
Inō Tadataka: Japan's Pioneer Cartographer
- Inō Tadataka meticulously surveyed Japan from coast to coast, providing highly accurate maps based on modern scientific techniques.
- His work, initiated at the age of 55, took 17 years and was funded by the Tokugawa shogunate after impressing Tokugawa Ienari with initial results.
- Inō applied celestial observations to determine geographical positions, achieving remarkable latitude accuracy despite challenges like weather and equipment limitations.
- His maps, produced at varying scales (1:36,000, 1:210,000, 1:430,000), influenced modern Japanese cartography, though many official copies were lost due to disasters.
- Inō's legacy was commemorated during the 2001 centennial of his first survey expedition.
Historical Maps: Key Figures and Contributions
- Strabo: Greek geographer known for "Geographica," providing a descriptive history rather than precise locations, influencing geographical understanding during the Byzantine era.
- Eratosthenes: Known as the "father of geography," he created a detailed world map, introduced grid systems, and divided Earth into climate zones.
- Hecataeus of Miletus: First known historian and geographer, he detailed the geography of Europe, Asia, and Africa in his comprehensive work "Periodos ges."
- Anaximander: Credited with the first world map emphasizing inhabited lands as known to ancient Greeks, providing significant geographical insight.
Ancient Map Examples
- Babylonian Map of the World: Circular design showcasing key cities and geographical features like rivers and mountains.
- Turin Papyrus Map: The oldest topographical map, created around 1160 BCE, illustrating the local distribution of geological features for quarrying purposes.
- Mammoth Tusk Map: Possibly the oldest map in Western Europe, depicting the landscape of the Pavlov region in a hunting context.
- Lascaux Cave Star Map: Believed to show celestial patterns and constellations, likely created for religious ceremonies.
Map Projections and Their Implications
- Maps or globes present different advantages and disadvantages regarding the representation of the Earth's surface.
- Globes accurately convey the Earth's geometry, true spatial relationships, and consistent scale but are impractical for extensive mapping.
- Various projection types inherently introduce distortions in area, shape, and distance:
- Cylindrical projections: Wrap around the Earth, but distort polar areas.
- Conic projections: Best for regional maps, useful for thematic representations.
- Azimuthal projections: Useful for polar maps and navigation, showing angles accurately from a central point.
- Pseudocylindrical projections use curved lines for meridians and parallels, facilitating thematic representation.
- Projections can also be categorized by their purpose, such as equal-area, conformal, equidistant, and compromise projections, each serving specific geographic needs.### Stereographic Map Projection
- Known as the azimuthal conformal projection, used since antiquity.
- A perspective projection that maps a sphere onto a plane using polar coordinates.
Lambert Azimuthal Equal-Area Projection
- Transforms a sphere to a disk while accurately representing area.
- Named after Swiss mathematician Johann Heinrich Lambert (1772).
- Also referred to as the Lambert zenithal equal-area projection.
Mercator Projection
- Created by Gerardus Mercator in 1569 as a conformal cylindrical projection.
- Maintains direction and shape but distorts sizes, especially away from the equator.
- Became essential for navigation.
Robinson Projection
- Developed by Arthur H. Robinson in 1963 for Rand McNally.
- Introduced in 1974, adopted by the National Geographic Society in 1988.
- Aesthetically pleasing; compromises on equal-area and conformal properties.
Goode Homolosine Projection
- A pseudocylindrical, equal-area composite map projection.
- Often presented with multiple interruptions to maintain area accuracy.
- Developed by John Paul Goode in 1923 as an alternative to Mercator.
Winkel Tripel Projection
- A modified azimuthal projection proposed by Oswald Winkel in 1921.
- Minimizes distortions in area, direction, and distance through arithmetic means.
AuthaGraph Projection
- An equal-area world map projection crafted by Hajime Narukawa in 1999.
- Uses triangles and tetrahedron methodology to minimize distortions, notably in Antarctica.
Miller Cylindrical Projection
- A modified version of the Mercator projection by Osborn Maitland Miller in 1942.
- Adjusts latitude scaling to retain equatorial scale while modifying polar regions.
Conformal Projections
- Preserve shapes of small areas, maintaining local angles at intersections.
- Useful for maps requiring accurate angles but varying area representation.
Changing Map Use Trends
- Younger users increasingly prefer platforms like Instagram and TikTok for discovery over Google Maps and Search.
- Google may adapt by indexing social media content for enriched search results.
- Younger generations lack familiarity with traditional paper maps, influencing expectations.
Blue Marble Photograph
- Taken by Apollo 17 in 1972, it was the first full image of the Earth.
- Influenced environmental awareness by showcasing Earth without borders.
Pale Blue Dot Concept
- Captured by Voyager 1 from 3.7 billion miles away in 1990.
- Carl Sagan emphasized Earth's fragility and humanity's shared experience.
Nighttime Earth Observations
- NASA's VIIRS satellite detects nocturnal lights, highlighting economic disparities globally.
- Dark areas indicate less economic development, especially in parts of Africa.
Daylight Savings Time
- Proposed by Benjamin Franklin in 1784 to maximize sunlight use and save candle usage.
- Introduced in Germany during WWI and adopted in the US in 1918.
- Ongoing debates over its effectiveness and potential alternatives; public divided on year-round implementation.
Time Zone Health Impacts
- Research suggests residing on the late sunset (western) end of time zones leads to reduced sleep and health issues.
- Individuals in later sunset areas face higher obesity and heart attack rates, and diminished productivity.
China's Unique Time Zone Policy
- Despite its vast size, China operates on a single time zone (Beijing Standard Time, GMT+8).
- This change, enacted in 1949, intended to enhance national unity and streamline operations.### Time Zones and Daylight Saving Time in China
- Western provinces, predominantly home to ethnic minorities, often perceive the standard time (BST) as oppressive.
- Farming communities prioritize agricultural work times based on sunlight, disregarding the official time.
- China briefly implemented daylight saving time from 1986 to 1991, but it was deemed inconvenient.
Fare Evasion and Technological Solutions
- Many commuters evade subway fares, leading to innovative technological controls.
- Washington D.C. is testing two new fare gates; one mimics saloon doors while the other features half-discs to prevent jumping.
- The DC Metrorail aims to gather data on these prototypes before expanding the program.
MTA's Fare Gate Pilot Program in New York
- The MTA in New York City has introduced high-tech gates to improve subway access but faces issues like 'piggybacking' where multiple people enter on a single fare.
- Pilot program costs around $700,000 and operates at major transport hubs, leading to a 20% increase in paid ridership at tested stations.
Speed Limiters in the UK
- New European regulations mandate speed limiters in all new vehicles sold in Europe starting July 6, 2022.
