2011 AP US PP - Science and Technology 1800 - 1850

  1. 1. Rob Scientific and Technological Developments: 1800-1850 Everett Davis and Rob Bultman EV
  2. 2. Everett Colt Revolver• Patented in 1836 by Samuel Colt who was 22 at the time.• It was modified and used by the U.S. Army in the Mexican War in 1846.• The Colt Revolver was the first rapid fire weapon ever invented and thus was a great leap forward in firearms technology. EV

  4. 4. Telegraph and Morse CodeEverett• In 1832-1837, Samuel F.B. Morse invented a feasible model of a one wire telegraph with his two partners Leonard Gale and Alfred Vail.• in 1837, the telegraph was announced to the public.• In 1838 Morse conceived the system of dots and dashes now known as the Morse Code and adopted the EV
  5. 5. Telegraph and Morse CodeEverett• Congress granted Morse $30,000 to fund his effort to wire the United States in 1842.• The first messages were in 1844 when Morse displayed the telegraph by sending the message, “What hath god Wrought?” from the chamber of the supreme court to baltimore’s mount Clair train depot.• Following railroad lines, the telegraph eventually spread across the United States and vastly EV

EV
  9. 9. Everett Electric Motor• The creation of the first electric motors is accredited to the British Michael Faraday, who created a model in 1831, and to the American Joseph Henry, who completed an improved model in 1831.• Henry’s model was more feasible than Faradays model, yet it still was not able to be implemented in any useful way. EV
  10. 10. Everett Electric Motor• In 1832 William Sturgeon invented the first electric motor that provided sustained rotation.• His device became the basis for most Direct Current electric motors today.• The electric motor has proved invaluable, being used in such things as new quiet military vehicles to cell phones.• Without them the new push for green vehicles would be severely hampered.

EV
  13. 13. Everett Steamboat• As the steam engine was relatively new technology, the steamboat did not become successful until Robert Fulton and Robert Livingston built the North River Steam Boat (a.k.a. Claremont) in 1807.• It took the new steamboat one day and six hours to go the 150 miles from New York City, NY to Albany, NY. EV
  14. 14. Everett Steamboat• Fulton and Livingston also built the New Orleans for travel along the Mississippi river between New Orleans, LA and Natchez, MS in 1812.• In 1809 John Stevens built the Phoenix, the first steamboat to travel in the ocean going from New York City to Philadelphia in 13 days.• The Savannah became the first steamboat to traverse the Atlantic, going from New York City to EV
  15. 15. Everett Steamboat• The steamboat primarily transported sugar, cotton, and people throughout the United States.• It had an exponential effect on the economy, turning any town on the river into a major city. EV

  17. 17. Rob The Sewing Machine• Elias Howe built the sewing machine in 1845.• The machine could stitch around 250 stitches per minute. (The fastest sewers could do about 50 per minute)• The machine could only sew short, straight distances at first. Elias would eventually take it to British companies to improve it. (Specifically Isaac Singer)• The invention gave commercial businesses the ability to produce more while cutting back on workers, causing industries like clothing to boom. EV

  20. 20. Rob John Deere’s Steel Plow• John Deere made his first steel plow in 1837.• The steel plow broke stubborn soil with ease and was also light enough to be pulled by a horse.• John’s invention would solve westerner’s problems of hard soil breaking their farm equipment, allowing westerner’s to develop their farmland.

  23. 23. Cyrus McCormick’s Mechanical MowerRob Reaper• In the 1830’s, Cyrus McCormick would create a machine that would reap crops at astounding rates.• The machine would be pulled by horses, and as the machine went over the grain it would cut it. A revolving wheel would then lay the grain beside it, where someone would rake it into piles.• McCormicks mower reaper, like other machines, reduced the amount of time it took to harvest. This meant they could grow more crops and have less workers. EV
