  • Inventors, Inventions and Transportation of the 19 th Century
  • Slide 2
  • Guglielmo Marconi Inventor of: The Radio By: Vivian www.nrao.edu/whatisra/ hist_prehist-s.shtml
  • Slide 3
  • Marconis Early Life He was the son of an Italian father and an Irish mother. He liked to experiment with physics and electronics. He successfully managed to send wireless signals over 1.5 miles away. He moved to England in 1879 to show off his new invention, the radio.
  • Slide 4
  • The First Radio In 1895, in Italy, Marconi sent the first radio signals. Users of the first radio sets had to listen using headphones. It was popular since the television had not been invented. Large radios were found in most homes. The existence of the radio waves was predicted in 1864, long before it was discovered. http://inventors.about.com/library/inventors/blradio.htm Click here to read more www.sierrapapa.it/ sp-ruoli.htm
  • Slide 5
  • How a Radio Works Sound waves vibrating at different frequencies are picked up in the studio by microphones and changed into electrical oscillations of the same frequencies. These signals are then passed through amplifiers to magnify them. www.ixbt.com/.../ barebone-asus-terminator2.shtml
  • Slide 6
  • How it has Changed our Lives Without radio, we would not have music. It has been a communication tool. Many famous people are heard on the radio. It helps us relax.
  • Slide 7
  • How Radio has Changed Now we have portable radios. There are more stations. Little radios have been invented that are known as walkie-talkies because theyre portable and you can talk to someone within miles away. Thanks to Mr. Marconi, we have the radio.

  • What is in a Radio? an antenna the intermediate-frequency amplifier and detector the audio-frequency processor and amplifier, the speakers. www.nrao.edu/whatisra/ hist_prehist-s.shtml

  • Todays Radio Today radios have more features. New features are always being added. Radios no longer look identical. They all look different. www.tuckerdogdesign.com/ vrooom/pics.html

  • Typewriter By: Alexander Samuel Soule and Carlos Glidden invented the first typewriter in 1867. www.lazybee.co.uk/1884/
  • Slide 11
  • Why did We Need this Invention? Writing on paper takes time. They invented the typewriter to help speed up communication. The typewriter makes it easier to read someones work. www.jsonline.com/.../ stories/0405sesqui.stm
  • Slide 12
  • Why was this Invention Important? This was important because it has changed life all over the world. This has changed the future by writing faster than a person writing. It was used before people got computers.
  • Slide 13
  • Typewriter vs. Writing on Paper Typewriter Pros: It doesnt take as long as writing with a pencil. You can keep on going without breaking a pencil. Cons: When you make a mistake you have to start all over. It is easy to mess up and hit the wrong keys. You might run out of ribbon or typing paper. Writing on paper Pros: You can still go on when you have a mistake because you would just erase it. You have a chance to change something when writing on paper. Cons: It takes a little longer than on a typewriter. If you dont have a pencil, how are you going to write. If you dont have an eraser, how are you going to erase your mistakes.
  • Slide 14
  • How has the Typewriter Changed our Lives? This has changed our lives by letting us type faster than a person can write. Without this invention, the idea of making computers might not have happened. This invention is so good because papers looked neater.

  • Transportation Improvements Clarissa Vivian Alex

  • Wagon & Stagecoach Wagon Was pulled by either oxen or horses It would take months to get mail and other belongings sent. People began looking for faster ways to send people and mail across the United States. Stagecoach In 1858, travelers found a new way to travel the stagecoach Were horse-drawn wagons that traveled in stages Moved more quickly than wagons Only traveled if weather was good www.temmeseed.com/ farm-antiques.htm www.ohtm.org/ 1849concord.html

  • Pony Express & Transcontinental Railroad Pony Express Young men delivered mail on horseback from Missouri to California in just 10 days. It lasted only 1 years and was like a 2,000 mile relay race Riders were mostly teenagers, some as young as 13 and paid $25 a week (which was a lot). It ended after telegraphs were invented. Transcontinental Railroad In 1862, the U.S government gave two companies the right to start building the Transcontinental Railroad. The Union Pacific began building tracks west from Omaha, Nebraska and the Central Pacific began building east from Sacramento, California. Both sides met in 1869 in Promontory Point, Utah. Train travel was a faster way to travel. www.americanwest.com/ pages/wexpansi.htm bushong.net/dawn/ about/college/ids100/

  • T-Model vs. Airplane Model T Car Henry Ford invented it in 1908. It cost only $950 at first and cost as little as $280 later. It was the first time cars were mass produced, making it keep enough for the average person to buy. It could only go 8 miles per hour. Airplane The Wright brothers build Flyer, the worlds first successful airplane in 1903. The flight lasted 12 seconds. Air flight today is possible because of them. www.musclecarclub.com/.../ ford-model-t.shtml www.first-to-fly.com/.../inventin.htm

  • The Effects of Transportation We hate to ride on slow transportation. We can get frustrated because it takes a long time. We would like faster transportation than riding on horses. People think faster is better than slower and so they kept inventing transportation that could go faster. Cars today can go as faster than 100 miles per hour. Cars back than could only go 8 miles per hour. Planes also go much faster and farther than they used to. Without faster transportation, we most likely would not be able to travel all over the world like we do today.
