Inventions+(2-1)

Telegraph: Telegraph is a wire-based electrical system that run on a dot-and-dash morse code. The original telegraph was invented by Samuel Soemmering in Bavaria in 1809. It could recieve and send only one message at a time. The regular telegraphs were slow and cover limited distances. The first electric telegraph was invented in England in 1838 by William Cooke and Charles Wheatstone. In Great Britain during the 1840's, they used the telegraph to establish standardized time.

Electricity: Around 600 BC, a Greek mathematician named Thales rubbed amber and animal fur made a attracted light objects. Though many other had noticed this reaction, Thales was the first one to record his findings. Static electricity is electricity moving into you. Otto Von Guericke made the first electric generating machine in Germany in 1660. In the 19th century, Michael Faraday held experiments with electricity and magnetism that led to the modern inventions of themotor, generator, transformer, telegraph, and telephone. Faraday was interested in finding why things were reacting the way they did, he wasn't planning on making so many useful inventions.

Railroads: The U.S railroad greatly matured during the 1800's and reached its peak of 300,000 total railroad miles in the 1920's. Work began on the Central Pacific track in 1863 and on the Union Pacific in 1865. The railroads faced the gigantic task of crossing the rugged Rockies and the towering Sierra Nevada. Thousands of european immigrants worked on these railroads. On May 10, 1869 the completion of a Transcontinental Railroad was completed. These tracks met at promontary, Utah. The railroads continued to expand during the 1860's. They played a major role in the Civil War by moving troops and supplies to battle. The South was at a disadvantage because it had far fewer railroad tracks than the North. By the end of the 1800's, the United States had five transcontinental rail lines.

Bessemer Process: The Bessmer Rrocess was the industrial process for the manufacture of stell from molten pig iron. It was the first inexpensive way of making steel. This process was invented by Henry Bessemer in England in 1856.

All of these inventions connect to today because they started out as something brand new at the time with not much knowledge about it all. Then with all of the changes made today it is a huge part of our life. Of course it is way more high tech now. media type="file" key="Group1 Podcast2.mp3" 2 Group 1
