Technological Advances in the 1920's


 The media in the 1920's changed drastically due to the introduction of the AM and FM radio systems that

were put into use at this time period. The first station to take advantage of this new way of communication was the KDKA radio station in Pittsburg. The impact of this new system made if very easy for people that wanted to spread their ideas to the working class do it with less effort then actually going to the people. An example of this would be when president Warren G. Harding first came over the radio at his inauguration for president on March 4, 1925 to 25 million people.


The movie business was not as we know it today in the 1920's. The movies then mostly consisted of short (less than 60 minutes) and silent movies. The movie Birth of a Nation

changed this, D. W. Griffiths movie was composed of over 1500 movie cuts when most movies of the time just consisted of only 100-200 cuts at most (SparkzNotes, 1). He also introduced specialized lighting and sound editing to make the movie seem and sound better. This movie touched on some very sensitive topics at the time though which include segregation of black and whites. Also it followed two families that were fighting during the civil war and their conflicts after the war with each other. D. W. Griffith took ever chance to make the south look as might as he could though. Overall this movie revolutionized the length and quality that movies were produced from here on.

The Car

Henry Ford led the growing automobile industry in the 1920s. They produced new and better models every year. The wages for producing cars increased as the price of cars decreased. The cars were becoming model_T_production.jpgincreasingly affordable, though 3 out of 4 cars were bought on installment plans. The roads designed for horses were becoming inefficient, so new roads were built. These were made to accommodate the automobile, along with new driving rules, road signs, and methods of controlling traffic. In these days, roads were poorly made, so tires needed to be able to pass through mud with ease. Touring vacations soon became popular, since this activity was available with a car. Tourist parks were created to assist the families and serviced their needs.

Albert Einstein

He was born on March 14, 1879 in Württemberg, Germany. Then six weeks later they moved to Munich. He did not know at the time but he was to become one of the most well known scientists of all time. He did have his challenges though. One of those unexpected challenges was that he nearly didn't make it into college because he failed his college entrance exam. Another challenge was the out break of the nazi party in Germany.

He did though have his breakthroughs in science which include the discovery of the Theory of Relativity. This theory is that the only thing constant in the universe is the speed of light in a vacuum and that everything else just slows light down and/or distorts it off its original straight line. Another part to the theory of relativity is that it is the only physical barrier for how fast anything can travel. This is because if you get anything faster than that you would go back in time.

Charles Lindbergh

Charles Lindbergh was an aspiring engineer from his childhood. He entered the University of Wisconsin. He would rather fly planes, so after two years he left the University and became a barnstormer. After a few years of that, he entered the military as a pilot and graduated flight school, first in his class. Soon, the Orteig Prize became available. Many pilots died attempting to fly from New York to Paris without stopping, but Lindbergh overcame this challenge and won the 25,000$ reward. He became famous and went on a flight tour funded by Harry Guggenheim and his father. This tour promoted aviation and, as a result, air mail became popular. While in Mexico, he met Anne Spencer Morrow. Eventually, he married her. They went on many trips to various parts of the world, and planned routes for commercial airlines. One day, their son of twenty months was kidnapped. His body was found roughly ten weeks later and a carpenter was put to blame and executed. Lindbergh went to Germany to examine their airplanes and was impressed. The Nazis there gave him a German Medal of Honor, which caused an outcry in America. When Lindbergh returned, he became involved in the noninvolvement movement. This movement meant that America should not join in World War II. People criticized him as a nazi sympathizer and even the President, Theodore Roosevelt, publicly denounced him. He decided to resign from the military after this. When Japan attacked Pearl Harbor, however, he left the noninvolvement movement and attempted to reenlist into the army. His request was denied. He went down to the Pacific War Area as an adviser for the US Army, and, even as a civilian, flew 50 combat missions. After the war, Dwight D. Eisenhower promoted Lindbergh to Brigadier General in the Air Force, and he served as an adviser for multiple airline companies. He died of cancer in his home in Maui

Freudian Psychology

Sigmund Freud studied psychology and created the practice of psychoanalysis.
A book on Freudian Psychology
He stated that the mind was like an iceberg, only about 10% of it conscious while the other 90% was unconscious. This means that most of the brain is not used, but operating for reaching pleasure through sexuality and aggression. The model Freud made of the brain consisted of three overlapping theories: the Economical theory, the Topographic theory, and the Dynamic theory. The Economical theory is the hydraulics of an unpleasure-avoidance through pleasure. The Dynamic theory suggests libido movements through the id, ego, and superego. The Topographic theory is the psyche as structured into conscious, preconscious, and unconscious layers.
