NOTES:
Chapter 8: Electric streetcars replaced horse drawn trolleys. Street cars were above and below to avoid crowed areas. Henry Ford introduced the Model-T in 1908, bikes were popular, and paved streets came about in the late 19th century. Model T was created by Ford Motor Company. The assembly line advanced mass production. Model T was produced every 24 seconds. Power controlled airplanes were created by the Wright bros. Airplanes are now used in warfare and transportation. Buildings had to be built upwards instead of outwards because of the decreasing space. Sanitation was bad during this time. Parks were a way to get out of the city and enjoy life and not be so cramped. Central park was created in 1850. Buildings started to have steel frameworks and got even taller and the elevator created an easier way to go up. Vacuum was invented in 1901. Television created in 1923. Alex Flemming created antibiotics in 1938. Revolutionized medical sciences. End of first section of presentations.
